PLUNGER TYPE WATER PUMPFIELD OF THE INVENTIONThe present disclosure generally relates to the technical field of positive5displacement hydraulic pumps, and particularly, to a plunger type water pump. More particularly, the present disclosure relates to a fully water-lubricated ultra-high-pressure plunger type water pump.BACKGROUND OF THE INVENTION10With the advent of the worldwide energy crisis and enhancement of people’s environmental protection awareness, water hydraulic technologies have been found to have advantages over oil hydraulic systems in many application fields (e.g., duringunderwater operations, or in buoyancy adjustment of manned submersibles) owing to the special physicochemical properties of the water medium. Accordingly, water hydraulic 15technologies have experienced a rapid development.However, because viscosity of the water is only about 1/30~1/50 of that of the commonly used hydraulic oil, it is less apt to form a water film and also has poorlubricity. Meanwhile, because of the strongly corrosive nature of the water andparticularly the sea water, selection of materials used in water hydraulic systems is20limited. This imposes great difficulties in design of friction couplings of waterhydraulic elements. For these reasons, in contrast to oil hydraulic pumps, matured axial water hydraulic pumps are mostly designed to work at a medium or high pressure, which is usually 12 MPa ~21 MPa.A fully water-lubricated sea-water/fresh-water pump in the prior art adopts a plate25valve for flow distribution, and has a flow rate of 10 L/min~170 L/min, a pressure of 14 MPa~16 MPa and an overall efficiency of higher than 82%. A schematic structuralview of such a pump is shown in FIG. 1. As shown, this fully water-lubricatedsea-water/fresh-water pump features a compact structure, full water lubrication of thefriction couplings, and easy maintenance. Unfortunately, such a pump also suffers from the following shortcomings:1. The maximum working pressure is 16 MPa, which cannot satisfy the needs inparticular applications, for example, in the buoyancy adjusting system of a large-depth(i.e., the submerging depth exceeds 3,000 meters) manned submersible.52. Distributing the flow by use of a valve plate is, on one hand, unsuitable foropen systems because the valve plate is sensitive to pollutants, and on the other hand,makes it difficult to ensure the volumetric efficiency when the water is high-pressurized.3. As a mechanism comprised of a swash plate and a shoe is used, a large lateralforce is applied by the plunger to the cylinder. Hence, serious abrasion will occur to the 10friction coupling after the water is high-pressurized.For water hydraulic pumps of higher pressures, a crank-shaft and connecting-rod structure is usually adopted, and a mineral oil lubricated structure with the oil and thewater being separated is used for the primary frictional coupling. Water hydraulicpumps of this structure are one of the kinds that are the most widely used around the15world, an example of which is a triple plunger pump in the prior art whose pressure range is 55 MPa~275 MPa. However, the water hydraulic pumps of this structure mainly have the following problems:1) They have a low rotation speed (100 rev/min ~500 rev/min), a bulky volume,and a small power-to-weight ratio. If the rotation speed is increased to decrease the20volume of the pump, the seal between the water cavity and the lubricant oil cavity would be overheated and even fail, which is particularly the case under high-pressureconditions. Meanwhile, the temperature of the oil in the closed lubricant oil cavity may also increase due to poor heat dissipation to cause degradation of the oil.2) Lubricant oil must be used for lubrication, which tends to cause oil pollution;25furthermore, when the water hydraulic pumps are used in deep sea environments, anadditional pressure compensation device must be used, which makes the whole structure very complex.SUMMARY OF THE INVENTIONAn objective of embodiments of the present disclosure is to provide a plunger type water pump that can achieve water lubrication of all friction couplings, surely have a high volumetric efficiency and a high power-to-weight ratio under ultra-high-pressureworking conditions, and reduce the frictional abrasion of the friction couplings under5high-speed heavy-load conditions so as to prolong the service life of the pump. Theplunger water pump can suitably adopt the sea water or fresh water as a working medium, and can also suitably adopt other fluids of a low viscosity as a working medium.To achieve the aforesaid objective, the plunger type water pump of the present disclosure comprises a pump body, a rotary unit and a plunger flow-distributing unit.10The pump body comprises a cavity body, a water pump inlet and a water pump outlet; the rotary unit comprises a rotary main shaft and is disposed in the pump body; and theplunger flow-distributing unit is disposed in the pump body. The plungerflow-distributing unit comprises a flat valve assembly, a plunger-shoe assembly and asupporting valve assembly. The plunger-shoe assembly is disposed inside the cavity15body and divides the cavity body into a high-pressure cavity, a low-pressure cavity and a lubrication cavity independent of each other; the supporting valve assembly is in fluidcommunication with the low-pressure cavity; the flat valve assembly is in fluidcommunication with the high-pressure cavity; and the rotary unit is disposed inside the lubrication cavity and is in fluid communication with the low-pressure cavity via a flow 20passage and the supporting valve assembly. Driven by the rotary main shaft, theplunger-shoe assembly reciprocates to impel the flat valve assembly and the supporting valve assembly to cooperate with each other so that the flat valve assembly takes in and discharges water through the water pump inlet and the water pump outlet respectively and the supporting valve assembly provides fluid lubrication for the rotary unit at the same25time.According to a preferred embodiment of the present disclosure, the flat valve assembly comprises an intake valve and a delivery valve formed integrally, an inlet of the intake valve is in fluid communication with the water pump inlet, an outlet of the deliveryvalve is in fluid communication with the water pump outlet, and an outlet of the intakevalve is in fluid communication with an inlet of the delivery valve.According to a preferred embodiment of the present disclosure, the rotary unitfurther comprises a reset spring, a set plate and a swash plate disposed in sequence on therotary main shaft; the plunger-shoe assembly comprises a stepped plunger, a connecting 5rod and a shoe, wherein the connecting rod is movably connected to the stepped plungerand the shoe respectively at both ends thereof by means of ball friction couplings; and aplunger passage is further disposed in the cavity body, with an end of the stepped plungerbeing slidably disposed in the plunger passage, wherein: one side of the set plate makescontact with the reset spring, the other side of the set plate makes contact with the shoe, 10and under the action of the reset spring, the set plate presses a bottom of the shoe tightlyagainst a surface of the swash plate so that rotating movement of the swash plate istransferred by the shoe and the connecting rod to the stepped plunger to impel the steppedplunger to reciprocate in the plunger passage, and the high-pressure cavity and thelow-pressure cavity independent of each other are formed between a small-diameter end 15of the stepped plunger and the plunger passage and between a large-diameter end of thestepped plunger and the plunger passage respectively.According to a preferred embodiment of the present disclosure, the plunger-shoeassembly further comprises a stepped plunger casing disposed in the plunger passage, andthe stepped plunger is disposed inside and slidably makes direct contact with the stepped 20plunger casing.According to a preferred embodiment of the present disclosure, the steppedplunger comprises recesses disposed on a surface thereof and damping holes that aredisposed radially and in fluid communication with the high-pressure cavity, and therecesses are in communication with the damping holes.25According to a preferred embodiment of the present disclosure, the surface of theswash plate that makes contact with the bottom of the shoe is applied with a polymericwear-resistant layer, and the polymeric wear-resistant layer is made of one ofpolyetheretherketone (PEEK) and polytetrafluoroethylene (PTFE).According to a preferred embodiment of the present disclosure, a ball end of the connecting rod that forms one of the ball friction couplings with the stepped plunger is formed of two semi-spherical rings tightened together, a surface of each of thesemi-spherical rings is formed with threads, and the semi-spherical rings are connected with one of the stepped plunger and the connecting rod by means of the threads.5According to a preferred embodiment of the present disclosure, the supporting valve assembly comprises a supporting intake valve and a supporting delivery valve, and the low-pressure cavity is in fluid communication with an outlet of the supporting intake valve and an inlet of the supporting delivery valve; the rotary unit further comprises an axial slide bearing and a radial slide bearing that mate with the rotary main shaft; and a 10fluid passage is disposed in the rotary main shaft and the pump body respectively toallow the supporting delivery valve to keep in fluid communication with the axial slide bearing and the radial slide bearing so that lubrication and supporting are achieved for the axial slide bearing and the radial slide bearing.According to a preferred embodiment of the present disclosure, a stepped15supporting cavity in fluid communication with the low-pressure cavity is disposed at the bottom of the shoe of the plunger-shoe assembly; and the rotary unit further comprises a damper disposed inside the pump body, the axial slide bearing is formed with an annular groove on an end surface thereof, the annular groove is in fluid communication with the damper, and the damper is further in fluid communication with an outlet of the supporting 20delivery valve through a flow passage formed inside the pump body.The embodiments of the present disclosure have but are not limited to the following technical benefits:1. Because all the friction couplings of the pump are lubricated by water as aworking medium, the volume of the pump is reduced, and the heat generated during25operation of the pump can be carried away by the working medium to ensure a lowthermal equilibrium temperature of the pump. Because the full water lubrication makes it unnecessary to replace the lubricant oil of the pump periodically, the maintenance issimplified and the operational cost is reduced; meanwhile, the potential environmentalpollution caused by leakage of the lubricant oil is avoided, which makes the pumpenvironment friendly.2. As the two closed cavities formed between the stepped plunger and the steppedplunger casing communicate respectively with the flat valve assembly and the supportingvalve assembly that are independent of each other, the high-pressure water output by the 5ultra-high-pressure pump and the low-pressure water used for static-pressure supportingand lubrication are separated from each other, which can ensure a high volumetricefficiency of the ultra-high-pressure water pump under ultra-high-pressure conditions andsurely provide the fluid supporting and lubrication for the friction couplings underhigh-speed heavy-load conditions.103. Through the static- and dynamic-pressure mixed fluid supporting, the problemof serious frictional abrasion of the slide bearings lubricated by water under high-speedheavy-load conditions is solved, and full water lubrication is achieved for thehigh-pressure water pump. The fully water-lubricated ultra-high-pressure water pump isenvironment friendly and easy to maintain; and particularly when used in deep sea15environments, it eliminates the need of an additional pressure compensation device ascompared to the conventional high-pressure water pump where the oil and the water areseparated from each other, and this can simplify the structure and improve the reliability.4. The drive mechanism in the form of a swash plate and a connecting rod canreduce the lateral force applied by the plunger to the stepped plunger casing, thus easing 20the abrasion of this friction coupling.5. The stepped plunger can reduce the contact specific pressure between the ballend of the connecting rod and the shoe under ultra-high-pressure conditions and increasethe fluid supporting area of the shoe, thus improving the fluid supporting and lubricationperformance between the shoe and the swash plate.256. The spherical recesses formed on the plunger further communicate with thehigh-pressure cavity via fine damping holes to form a dual damping effect between theplunger and the stepped plunger casing, which can prevent sticking of the plunger andreduce the direct abrasion therebetween. The recesses on the surface of the plunger alsohelps to reduce the contact pressure between mating surfaces, restrict movement ofabrasive particles and locally form a dynamic-pressure supporting effect, thus solving the problem of abrasion of the plunger coupling under high-speed heavy-load conditions and prolonging the service life of the ultra-high-pressure pump.7. The flat valve is an integrated assembly in which the intake valve and the5delivery valve are formed integrally, so it can be replaced promptly during maintenance to shorten the maintenance time. The flat valve is of a compact ball valve structure and adopts a soft material and a hard material in combination for sealing. Specifically, the valve seat is made of polyetheretherketone (PEEK) and the valve core is made of aceramic material. This not only improves the sealing reliability under high-pressure10conditions, but also reduces the impacting noise between the valve core and the valveseat, thus reducing the noise of the overall pump. The valve core is made of anengineering ceramic material. Because of the higher hardness and lower density of the ceramic material as compared to metal materials, this improves the resistance tocavitation corrosion, decreases the weight of the valve core, and improves the response 15characteristics and shortens the lagging time of the flat valve, thus improving thevolumetric efficiency under high-speed conditions.BRIEF DESCRIPTION OF THE DRAWINGS20In order to more clearly describe the technical solutions of the embodiments of the present disclosure, attached drawings to be used in the detailed description of thedisclosure will be briefly described hereinbelow.

Referring to the drawings, like numbers indicate like parts throughout the views. As used in the15description herein and throughout the claims that follow, the meani ng of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein and throughout the claims that follow, the meaning of “in”includes “in” and “on” unless the context clearly dictat es otherwise.A schematic structural view of a plunger type water pump according to an20embodiment of the present disclosure is shown in FIG. 2. The plunger type water pump comprises a pump body, a rotary unit and a plunger flow-distribution unit. The pump body comprises a cavity body, a water pump inlet and a water pump outlet. The rotary unit comprises a rotary main shaft 1. The plunger flow-distributing unit mainlycomprises a plunger-shoe assembly 23, a flat valve assembly 13 and a supporting valve 25assembly. The supporting valve assembly comprises a supporting intake valve 17 and a supporting delivery valve 18. The plunger-shoe assembly 23 is disposed in the cavity body and divides the cavity body into a high-pressure cavity 16, a low-pressure cavity 19 and a lubrication cavity 28 independent of each other. The supporting valve assembly isin fluid communication with the low-pressure cavity 19, the flat valve assembly 13 is in fluid communication with the high-pressure cavity 16, and the rotary unit 28 is disposed inside the lubrication cavity 28 and is in fluid communication with the low-pressurecavity via a flow passage and the supporting valve assembly.As shown, the pump body is mainly comprised of an end cover 10, a cylinder 95and an enclosure 3. An end of the cylinder 9 is connected to the enclosure 3, and theother end of the cylinder 9 is provided with the end cover 10. Cavities in the end cover 10, the cylinder 9 and the enclosure 3 together form the aforesaid cavity body. Therotary main shaft 1 is fixed in the lubrication cavity 28 formed by the cylinder 9 and the enclosure 3. A plurality of plunger flow-distributing units (generally there are three to 10seven plunger flow-distributing units depending on different requirements on flowpulsing of the water hydraulic pump in different service environments) are uniformlydistributed along a same circumference with the rotary main shaft 1 as a center.Hereinbelow, the structure and the operation process will be detailed.A left end surface of the back end cover 10 is formed with two threaded holes for15use as an inlet and an outlet of the ultra-high-pressure water pump respectively, and aright end surface of the back end cover 10 is formed with a flow hole 11 and an annular flow groove 14. Stepped holes, a number of which is equal to the number of the plunger flow-distributing units, are formed in a radial direction and uniformly distributed in acircumferential direction of the back end cover 10. Each of the stepped holes is formed 20with threads at the outer side for installing and fixing the flat valve assembly 13. Once the flat valve assembly is installed in place, a locking nut 12 is used to lock the flat valve assembly 13 so that loosing of the flat valve assembly 13 under the action of the cycling hydraulic pressure can be prevented, thus improving the reliability in use of the seawater/fresh water pump in underwater environments.25As shown in FIG. 3, the flat valve assembly comprises a valve body 27, an intake valve and a delivery valve. An inlet of the intake valve communicates with an inlet of the water pump via the annular flow groove 14, an outlet of the intake valvecommunicates with an inlet of the delivery valve, and an outlet of the delivery valvecommunicates with an outlet of the water pump. As shown, the delivery valve isinstalled at a top portion of the valve body 27, and the intake valve is installed at abottom portion of the valve body 27. The delivery valve comprises, in sequence from top to bottom, a delivery valve locking nut 35, a delivery valve spring 34, a deliveryvalve core 33 and a delivery valve seat 32; and the intake valve comprises, in sequence 5from top to bottom, an intake valve spring 31, an intake valve core 30, an intake valve seat 29 and an intake locking nut 28. An interface between the delivery valve and an intake valve serves as both the outlet of the intake valve and an inlet of the deliveryvalve. By designing the intake valve and the delivery valve into a single assembly, the flat valve assembly can be replaced as a whole during the maintenance period to shorten 10the mean time to repair (MTTR) and to improve the on-site maintenanceability.The radial arrangement of the flat valve assembly reduces the axial dimension of the water pump and increases the power-to-weight ratio. The flat valve adopts a seal form of a ball valve and adopts a soft material and a hard material in combination forsealing; specifically, the valve seat is made of PEEK and the valve core is made of15ceramic. Such a compact structure not only improves the sealing reliability underhigh-pressure conditions, but also reduces the impacting noise between the valve coreand the valve seat, thus reducing the noise of the overall pump. Because the valve core is made of a ceramic material which has a higher hardness and a lower density than metal materials, this improves the resistance to cavitation corrosion, decreases the weight of the 20valve core, and improves the response characteristics and shortens the lagging time of the flat valve, thus improving the volumetric efficiency under high-speed conditions.The cylinder 9 is formed with a flow passage 8 in order for the water pump inlet to communicate with the lubrication cavity. In the axial direction, the cylinder 9 isformed with a stepped hole in communication with the plunger piston, and in the radial 25direction, stepped holes twice as many as the plunger flow-distribution units aredistributed and communicate with the axial stepped hole in groups of two. The stepped plunger casing 7 is installed in the axial stepped hole, and each group of radiallydistributed stepped holes is used to install the supporting intake valve 17 and thesupporting delivery valve 18. The inlet of the supporting intake valve 17 communicates with an inlet of the ultra-high-pressure sea water pump via the flow passage 15 and the annular flow groove 14 of the back end cover. The stepped plunger assembly 23 isinstalled in the stepped plunger casing 7, as shown in FIG. 4. The stepped plungerassembly 23 comprises a stepped plunger 36, semi-spherical rings 38, a connecting rod537 and a shoe 39. The connecting rod 37 is formed with an elongate damping hole thatcommunicates with the supporting cavity 42 located at the bottom of the shoe 39, and the supporting cavity 42 is of a multi-step structure. At a large-diameter end of the stepped plunger is formed with a stepped threaded hole, and a ball socket is formed at the bottom of the threaded hole. Each of the stepped plunger assemblies 23 has two semi-spherical 10rings 38 as shown in FIG. 5, which are formed by fabricating a part having male threads and a ball socket and then splitting the part into two pieces. The male threads of the two semi-spherical rings 38 mate with female threads of the plunger, and the ball socketmates with the ball end of the connecting rod. The two ends of the connecting rod 37 are ball ends of different sizes, with the smaller ball end being adapted to mate with the 15ball socket of the plunger. Then, the pair of semi-spherical rings is threaded into thethreads of the stepped plunger 36 so that the connecting rod is connected to the stepped plunger 36 with a ball friction coupling being formed therebetween. This structureeliminates the plastic deformation that would occur on the plunger surface when thesmaller ball end of the connecting rod is connected to the plunger by means of the20common rolling process, so the accuracy of fit between the plunger surface and theplunger hole is improved to result in both an improved sealing performance andimproved friction behaviors. The larger ball end of the connecting rod and the ballsocket of the shoe mate with each other, and may be connected together through a rolling process to form a ball friction coupling. The stepped plunger 36 is formed with25spherical recesses 41 and fine damping holes 40 on a surface of the small-diameter end, as shown in FIG. 6.The drive mechanism in the form of a swash plate and a connecting rod mainly helps to reduce the lateral force between the stepped plunger 36 and the stepped plungercasing 7 as well as the bending moment borne by the stepped plunger 36. Between the small-diameter end of the plunger and the stepped plunger casing 7 is formed thehigh-pressure cavity 16, which communicates with the water pump outlet via the flatvalve located on the end cover so as to output the ultra-high-pressure water; and between the large-diameter end of the plunger and the stepped plunger casing 7 is formed the5low-pressure cavity 19, which communicates with the supporting cavity 42 of the shoe 39 so as to provide the static-pressure supporting between the shoe 39 and the swash plate.The static-pressure supporting and the dynamic-pressure supporting generated by thesupporting cavity 42 of the multi-step structure at the bottom of the shoe 39 coact toimprove the supporting performance between the shoe and the swash plate. The water 10medium used for supporting flows through an axial gap between the shoe 39 and theswash plate into the lubrication cavity 28 (as shown in FIG. 2) which communicates with the pump inlet. The low-pressure cavity 19 further communicates with the outlet of the supporting intake valve 17 and the inlet of the supporting delivery valve 18 to providepressure supporting for the axial slide bearing 6 and the radial slide bearings 5 and 20 via 15the supporting delivery valve 18, thus accomplishing the static- and dynamic-pressuremixed supporting and lubrication. The spherical recesses 41 on the surface of thestepped plunger 36 communicates with the high-pressure cavity 16 via the fine damping holes 40 and a row of recesses located on an end of the stepped plunger so as to provide a dual damping effect between the stepped plunger 36 and the stepped plunger casing 7.20This solves the problem of sticking of the plunger caused by reducing the gap between the stepped plunger casing 7 and the stepped plunger 36 in order to improve thevolumetric efficiency of the ultra-high-pressure pump, and makes it less likely for thestepped plunger 36 and the stepped plunger casing 7 to make direct contact with eachother. These recesses not only reduce the contact stress between the mating surfaces25and restrict movement of abrasive particles, but also locally form a dynamic-pressuresupporting effect. By means of the connecting rod mechanism, the two-stage damping and appropriate design of the surface morphology, abrasion of the plunger frictioncoupling under high-speed heavy-load conditions is avoided.。
美国发明专利文章格式
美国发明专利文章结构以美国的「发明专利」为例,专利内容通常分为四大部份:(一)封面:包括专利的基本数据﹙如专利号码、专利申请日、发明人姓名等﹚和发明摘要;(二)图示:包括描绘发明的图示;(三)说明书的内容部分:包括文字描述;以及(四)申请专利范围:包括请求项(或称权利项)定义专利的保护范围。
(一)封面:封面提供专利的基本数据,在每一笔基本数据旁都印有以[ ]框起来的号码,也就是大家熟知的INID 码(Internationally agreed Numbers for the Identification of Bibliographic Data code;INID code)。
每个INID 码各代表不同的数据项,例如[54] 代表发明名称,[76]代表发明人姓名与户籍地。
由于INID 码是国际统一的号码,因此各国的专利都是以[54] 来表示发明名称。
封面上还包括摘要,对发明作简单描述,在摘要下方还会指出专利所包括的请求项与图示张数。
另外,封面还可能包括专利的代表图示。
以下是美国专利中常见INID码及代表的意义:[19] 公告的国家或组织:出现在2001年1月2日前公告的美国专利中,显示在专利封面左上角的United States Patent 右方,位于下方的英文为第一发明人的姓。
[12] 公告型态:出现在2001年1月2日后公告的美国专利中,会显示United States Patent,位于下方的英文为第一发明人的姓。
[11] 专利号码:出现在2001年1月2日前公告的美国专利中,不同的专利种类有不同格式的专利号码。
举例来说,「发明专利」的专利号码为纯数字的序号,如6,666,666。
「新式样专利」的专利号码以字母D开头(D表示Design)后加数字序号,如D333,333。
「植物专利」的专利号码以PP开头后加数字序号,如PP8,112。
[10] 专利识别码:出现在2001年1月2日后公告的美国专利中,举例来说,US 6,541,321 B1 代表美国发明专利第6,541,321 号,其中的B1 表示专利在获准前并没有被早期公开过。

美国专利荧光灯镇流器及其保护电路(专利号:5387846 授权日:1995.2.7)李志刚译摘要:本专利公布了一种能够实现节能的电子镇流器电路(1A),用以驱动荧光灯管。
该电路具有功率因素高,谐波失真低,射频干扰小的特性。
它包括一个独特的直流电源(4),该电源是由接收交流输入信号的高通滤波器(8)、二极管整流桥(6)和快速恢复二极管(D2)组成。
整流桥作为第一级整流,快速恢复二极管作为第二级整流,第一级是低频整流,第二级是高频整流。
稳流电容(C4)接在直流电源的第一级整流和第二级整流连接点之间,用来驱动荧光灯管。
第二级整流后,接入触发器和高频振荡器,并提供镇流器电路工作所必需的直流。
该镇流器接有保护电路(30),一旦灯管故障,或灯与镇流器断开,或发生异常工作状态,振荡器立即停振,防止镇流器损坏。
参考专利文献:本专利是对Ser.No.07/799,209专利(1991.11.27,现已失效)的部分延续。
发明背景1. 技术领域本专利发明了一种紧凑节能的电子镇流器电路,能有效驱动荧光灯及紧凑型荧光灯,具有功率因素高、总谐波失真低、射频干扰小的特性,适合各类厂家生产的灯管。
此外,它还接有保护电路,一旦灯管故障,或灯管与镇流器断开,或发生异常工作状态,能防止镇流器损坏。
2. 技术背景荧光灯及紧凑型荧光灯系统是人们熟悉的照明装置。
荧光灯系统包括灯管和驱动灯管的独立式电子镇流器或适配器。
紧凑型荧光灯系统,灯管与镇流器是一个整体。
传统的荧光灯镇流器较重,体积大,能耗高,功率因素低。
对于一般的紧凑型荧光灯镇流器,如果不牺牲尺寸,其功率因素也较低。
在大多数情况下,这些镇流器的总谐波失真不能完全符合政府的规定。
由于紧凑型节能灯和电子镇流器是一个整体,当灯管损坏和寿命终结时,整个紧凑型照明系统都将废弃,造成不必要的浪费。
实际上,镇流器的生产成本比灯管高,预期寿命更长。
由于荧光灯故障,镇流器也会同时发生故障,从而降低镇流器的寿命,增加更换频率,提高营运费用。
当灯管(即负载)与镇流器断开,或接线错误,或故障灯管与镇流器相连,或灯管遭到浪涌电压的冲击,或环境温度高使灯管电气特性改变时,如果加电,也会使镇流器发生故障。
因此,我们希望克服上述荧光灯照明装置的缺陷,提出一种重量轻、紧凑型节能的电子镇流器,要求总谐波失真低、射频干扰小、功率因素高(达0.9以上)。
我们还希望镇流器与灯管分体,便于更换灯管,不必将镇流器扔弃。
此外,镇流器也必须遵守政府的有关规定,能与各类厂家生产的灯管相匹配。
我们希望镇流器本身带有保护电路,减少因灯管故障而发生镇流器故障损坏的现象。

专利的详细说明如图1所示,本专利公布的分体式电子镇流器线路1能实现相对紧凑、重量轻、成本低、高效节能,与荧光灯管2相接,也能用于紧凑型荧光灯。
它包括一个独特的直流电源4,能接入120V60Hz 的输入信号。
电源4包括一对滤波电容器C1和C2,它们相互并联。
接在滤波电容C1、C2之间的是一对铁氧体扼流圈L1A和L1B。
电容C1、C2和铁氧体扼流圈L1A、L1B相互连接形成高通滤波器8。
注意,滤波器8的铁氧体扼流圈L1A和L1B必须反接,有助于抑制对交流电网产生的射频干扰,从而符合政府对于干扰的有关规定。
滤波器8与二极管整流桥6相连,以通常的方法提供全波整流。
直流电源4还包括一对整流级输出电容C3和C5,它们相互并联,与二极管整流桥6相连。
快速恢复二极管D2接在输出电容C3和C5之间。
输出电容C5的容量与输出电容C3相比非常大,有益于实现高功率因素。
镇流器电路1直流电源各元件的最优值举例如下:C1=0.1~0.22μFC2=0.005~0.01μFC3=0.005~0.01μFC5=22~33μF1A=0.01~0.015HL1B=0.01~0.015H电源4的第一级整流输出端10是整流桥6、二极管D2、输出电容C3、稳流电容C4和电阻R1的公共端。
稳流电容C4通过电容C7与荧光灯灯丝12和14串联,电容C7接在灯丝12和14之间,既可以作为荧光灯2的一部分(如图所示),也可以作为镇流器电路1的一部分。
灯丝14与铁氧体扼流圈L2、铁氧体振荡变压器16的线圈L3A串联。
变压器16的次级线圈L3B经限流电阻R3与功率晶体管TR1的基极相连。
电源4的第二级整流输出端11是快速恢复二极管D2、输出电容C5和晶体管TR1集电极的公共点。
二极管整流桥6和快速恢复二极管D2对电源4两次进行整流,为线路1提供能获得高功率因素所必需的直流功率。
第一级整流输出端10是电流的总驱纽,二极管D2对二极管整流桥6整流后的输出电流以及流经稳流电容器C4和灯管2的高频电流进行再整流。
因而,镇流器电路1其余各部分工作所必需的全部直流可以由第二级整流输出端11提供。
晶体管TR1的射极经电阻R11与铁氧体振荡变压器16的线圈L3A、L3B和电阻R7相连作为公共点18。
电阻R11在反馈回路内与晶体管TR1射极、基极之间的电阻R7相连。
功率晶体管TR2的集电极与公共点18相连,射极经电阻R12接地。
电阻R12在反馈回路内与晶体管TR2射极、基极之间的电阻R6相接。
晶体管TR2的基极经限流电阻R4和触发二极管D4接到公共点20。
线圈L3C 与线圈L3A、L3B形成磁耦合,为铁氧体振荡变压器16提供电抗,线圈L3C通过电阻R2接到公共点24,电阻R4、R6和晶体管TR2的基极也接到公共点24。
在荧光灯2接入镇流器电路1的情况下,功率晶体管TR1、TR2,铁氧体扼流圈L2,铁氧体变压器线圈L3A、L3B、L3C,电容C3、C4和快速恢复二极管D2相互连接,使镇流器电路1提供高频振荡和大功率输出,有效地驱动荧光灯2。
当灯管2从镇流器卸下时,高频振荡将停止。
电阻R1和R8串联,组成分压器网络。
电阻R9的一端经公共点20接到触发二极管D4,另一端与电阻R1、R8相接。
电阻R1、R4、R9,触发二极管D4和电容C6相互连接,为镇流器电路1提供触发功能。
二极管D5跨接在与晶体管TR1射极相接的电阻R11和晶体管TR1集电极的两端,电阻R5与二极管D5并联。
另一个二极管D6接在公共端18和地之间,跨接在与晶体管TR2射极相接的电阻R12和晶体管TR2集电极的两端。
二极管D5、D6用于保护晶体管TR1、TR2,防止因浪涌电压而损坏。
二极管D3的一端与触发二极管D4、电阻R9和电容C6的公共点20相连,另一端经电阻R10与变压器16的线圈L3A的公共点18相连。
在镇流器电路1开始高频振荡后,二极管D3和电阻R10使触发停止。
现在,我们来叙述一下图1镇流器电路1的工作原理。
60Hz的电源或线路电压信号首先经过直流电源4的高通滤波器8,然后被二极管整流桥6整流。
120Hz半波整流信号通过稳流电容C4调制成高频电流(数十千赫)(见图4b的波形)。
电容C4的大部分高频电流流过电源4的第一级整流输出端10,经二极管D2整流后流到输出电容D5。
然而,也有少量流过电容C4的高频电流经输入端10流到输出电容C3。
如前所述,高通滤波器8的电感量较小,60Hz 线路电压采用小电抗,高频电流采用大电抗,并与输出端10的120Hz电流相迭加。
对于镇流器电路1触发器的工作,流过电阻R1、R9的正向电流将被加到电容C6。
当电容C6两端的电压增加到30~32V时,触发二极管D4将产生脉冲电流,经电阻R4流至功率晶体管TR2的基极,使镇流器电路1的振荡器被触发。
当电容C6两端的电压下降到3V时,触发停止。
铁氧体振荡器16的线圈L3A的电流被磁耦合到线圈L3B、L3C,因此,功率晶体管TR1、TR2以一般半桥方式工作,轮流导通,振荡器将在40-70KHz的范围内工作(视所使用的荧光灯2的特点而定)。
振荡器为一般镇流器所共有,我们在此不再详述镇流器电路1振荡器的工作原理。
铁氧体线圈L2与灯丝14、变压器16的线圈L3A串联,提供两种重要的功能。
在荧光灯2电离和点火之前,铁氧体扼流圈L2与电容C7相配合,在灯丝12、14之间提供点燃灯管2气体所必需的高压。
当灯管2点燃之后,铁氧体扼流圈L2限流,使灯管2的工作稳定。
假设 XL =2лfL,式中:XL =L的电抗(等效电阻)f =频率L =电感如果2лL已知,则RL与f 成正比。
也就是说,频率增加,电抗也增加,因而输入电流的波形也会产生相应的变化。
对于图2-4,以上是最好的说明。
图2a、3a、4a是一般电子镇流器的波形,图2b、3b、4b是图1电子镇流器电路1的直流电源4波形。
实际上,一般镇流器电源的输出电容的充电时间很短。
因而,其输入电流是脉动的(如图2a 所示),电流有效值很大,功率因素仅为0.5左右,谐波电流一般在90%以上。
在镇流器电路1的直流电源4中,输出电容C3上的120Hz半波电流与镇流器电路1振荡器产生的40-70kHz电流互相调制。
高通滤波器8和二极管D2使电流通过第二级整流输出端11加到输出电容C5上,波形非常平滑(如图4b所示)。
因此,对照图2a和图2b,与一般镇流器的交流输入电流有效值相比,图1直流电源4的交流输入电流有效值约减少39%或更多。
改变图2a所示的输入电流脉冲波形,使图2b的输入电流更接近于正弦波形,将大大降低输入电流的谐波成分,使功率因素从0.5上升到0.9以上。
