Type DTL, De-energized Tap Changer Application, Installation & Selection GuideIZUA 4643-212Instruction LeafletScopeThis leaflet contains general information about ordering and installing the type DTL de-energized tap changer. These in-structions do not describe all possible contingencies that may arise during installation, operation, or maintenance of the tap changer, nor does it describe all details and variations of the equipment. If you require additional information regarding this installation and the operation or maintenance of your equip-ment, contact the local representative of ABB.Safety DefinitionsSafety notations are intended to alert personnel of possible personal injury, property damage, or even death. They have been inserted in this instructional text prior to the step in which the condition is cited.The safety notations are headed by one of three hazard intensity levels, which are defined as follows:DANGER- immediate hazard that will result in severe personal injury, property damage, or death.WARNING- hazard or unsafe practice that could result in personal injury, property damage, or death. CAUTION- hazard or unsafe practice, which could result in minor personal injury, or property damage. IntroductionT he type DTL de-energized tap changer is one of a family of ABB tap changers for power transformers. A de-energized tap changer is a switch that is connected to the winding taps of the transformer. When the tap changer is moved from one position to another the amount of the tap winding connected into the circuit is changed. This permits the adjustment of the voltage ratio of the transformer to best suit the voltage require-ments at the transformer’s installation site. The de-energized tap changer is usually installed into the high voltage circuit of the transformer, and most of the time, it is used to adjust the primary voltage of the transformer within a 10 percent range in 5 steps.D A N GE RTHE TYPE DTL TAP CHANGER IS A DE-ENERGIZED TAP CHANGER AND MUST BE OPERATED ONLY WHEN THE TRANSFORMER IS COMPLETEL Y DE-ENERGIZED. THIS TYPE OF TAP CHANGER MUST NEVER BE OPERATED WHEN THE TRANS FORMER IS ENERGIZED. OPERA-TION WHEN THE TRANS FORMER IS ENERGIZED IS DANGEROUS AND WILL RESULT IN SEVERE PERSONAL INJURY, PROPERTY DAMAGE, OR DEATH.The type DTL tap changer is a modular, electrically, linear-type tap changer with an external operating mechanism. It is most commonly available as a 5-position device. (See Figure 1) The DTL is designed to be mounted in the space between adjacent transformer coils and to be held in place by an insu-lating framework, which is attached to the transformer super-structure. Figure 2 shows a typical DTL installation.RatingsThe type DTL tap changer is available in two basic current ratings, 500 A (Figure 3) and 1000 A ( Figure 4), and is of-fered with, or without, electrostatic shielding (see page 3). The ability to locate the type DTL tap changer in between each phase coil permits very direct tap lead routing with a minimum of bends.Figure 1.Tank Wall or GroundFigure 2.2ABBABB31See Figure 42This is dependant on how the tap changer is applied to the transformer (electrical clearance distances) and electronstatic shielding used.3Based on a steady state contact temperature of 15º C at a continous current equal to 120% of the rated current.Figure 3. Type DTL 500 AFigure 4. Type DTL 1000 ATable 1. Presents the ratings4ABBConstruction Details and FeaturesBasic InformationThe type DTL de-energized tap changer is constructed from six major components:1. Main Housing2. Sliding Rack3. Moving Contact (Sliding Contact)4. Common Contact5. Stationary Contacts6. Drive Shaft and External Operating Mechanism Figure 5 shows the first six major components and somemounting details.Main HousingThe main housing consists of two flat insulating plates fastened together with insulating bolts and spacers to form a sandwich-like structure. The stationary contacts and the common contact are bolted to the main housing at its upper end and the driving gear pinion and shaft connector are attached at its lower end. The main housing contains two sets of mounting holes, which are used to bolt the tap changer to the transformer framework. The flat insulat-ing plates are machined from high strength, electrical grade, low power factor Micarta™. This structure carries all of the mechanical loads created by the weight of the tap leads and the thrust and weight of the drive shafts.Sliding RackThe sliding rack rides in the space between the two main housing plates. The moving contacts are attached to the sliding rack at its top end. The bottom end of the sliding rack is machined into a linear Geneva gear, which is moved vertically by the rotary actionFigure 5. Major Components of the DTL Tap Changerof the drive pinion. One full turn of the drive pinion moves the sliding rack from one stationary contact to the next. The sliding rack is machined from the same Micarta™ material as the main housing plates.ContactsThe stationary contacts and the common contact are machined from 3/4 of an inch (19 mm) diameter copper bar stock.In the 500-Ampere switch, these contacts are bolted between two Micarta plates of the main housing. Two bolts are used for each contact. The bolt heads and nuts are shielded with special toroidially shaped washers to minimize electrical stress concentration.In the 1000-Ampere switch, there is a set of two stationary and two moving contacts for each tap position. A copper connector is bolted between each pair of stationary contacts. Four bolts are used to secure each set of stationary contacts and connector.The connection between the stationary contacts and the transformer’s tap leads is made using the standard ABB UZ tap changer cable lug (see UZ technical guide 1ZSE 5492-104). This lug accepts the tap cable into a tubular recess; the cable can be held in place by either crimping or brazing to the lug. The other end of the lug contains a captive steel, M10 (0.40 inch) bolt with a hex recess. The cable lug attaches to the stationary contact by means of this bolt, which is threaded into a tapped cross-hole on the end of the stationary contact. In the 1000-Ampere switch, the tap lead is connected to the copper connector between the contacts. The cable lug is available in several sizes to suit the tap cable diameter.The moving contact assembly is a clam-shell type of contact. The spring loaded contact plates slide over the stationary contacts. All stationary and moving contacts are made from silver plated cop-per.Two springs precisely control contact pressure. These springs are designed to interact with the contact plates and the support struc-ture to provide uniform and consistent contact pressure. This fea-ture permits the tap changer to have a relatively low driving torque and high fault current withstand capability by preventing contact bounce and arcing during faults.The action of the sliding contact over the moving contact during a tap change creates a good wiping action that cleans contact sur-faces. This wiping action insures a solid, low resistance electrical connection.2. Sliding Rack4. Common Contact Linear Geneva GearElectrostatic Shield5. Stationary Contacts (5)6.Drive Shaft1. Main Housing Lower Mounting Holes (2)Upper Mounting Holes (2)3. Sliding Contact AssemblyABB5tap action allows the driving mechanism system to absorb any backlash in the entire tap changer structure and still provide pre-cise positioning of the tap changer contacts.To make a tap change the operator must perform two separate actions:1. Pull a fixing pin which frees the mechanism shaft2. Turn the operating handle 360 degreesA number on a Geneva wheel that is visible through a view-port indicates the position number. A position number is only fully vis-ible when the tap changer is in position. Positive mechanical stops are built into the tap changing mechanism that will prevent turning past the lowest and highest positions. The external mechanism can be padlocked in any position.Electrostatic ShieldingElectrical spacing requirements between the tap decks and the tank wall and between the tap decks and adjacent phases or other metallic objects is a complex subject. When designing the transformer, required distances should be calculated between phases and between phase and ground for the DTL tap changer.Two levels of shielding and insulation are available for the tap decks.1. Unshielded decks are typically used for applications that have an impulse voltage withstand requirement of 250 kV or less (Figure 8).2. For applications that require an impulse voltage withstand of greater than 250 kV , up to 650 kV , two epoxy coated, aluminum electrostatic shields are bolted to the tap deck (Figure 9).Figure 8. No Shield The linear Geneva gear is machined into the sliding rack that carries the sliding contacts. The drive gear pinion is installed between the two main plates such that the drive pinion engages the linear Geneva gear.The interphase shafts are Micarta tubes that are attached to the drive pinions by means of a bolt through a slotted hole in the shaft. The main drive shaft is a telescoping tube assembly. This assembly connects the first tap deck drive pinion to the ball joint coupling on the inner end of the operating mechanism.The combination of slotted interphase shaft connections and telescoping drive tube allows for minor misalignments between tap changer components and permits the shafts and operating mechanism to adjust to the dimensional changes that occur as the transformer responds to temperature variations.The operating mechanism uses a packing gland backed up by a secondary o-ring to form a redundant shaft seal between the transformer and the atmosphere. The flange of the operating mechanism is gasketed and bolted to a mounting boss, which is welded to the transformer tank.The external operating mechanism drives the tap changer’s operating shafts so that one complete revolution of the external handle indexes each tap deck one position. This one-turn-per-Figure 9. With ShieldsContact Plating:•The sliding contacts are silver plated.•The stationary contacts are silver plated.•The common contact is silver plated.Details of the contact system can be seen in Figure 6.Driving SystemThe drive system consists of four parts:1. Linear Geneva gear 2. Drive pinion3. Interphase shafts (insulating material)4. Main drive shaft and external mechanism These parts are illustrated in Figure 7.4. External Mechanism2. Drive Pinion and Shaft3. Interphase Drive Shaft1. Linear Geneva Gear Telescoping Drive ShaftFigure 7.6ABBStandard ConfigurationsThe type DTL tap changer is built in one standard configuration. The operating mechanism may be ordered for mounting on either the left or right hand side of the tap decks.An ordering data sheet is provided to permit the customer to specify mechanism location, critical spacing dimensions, and crimp lug sizes.The standard switch configuration consists of three vertically mounted single tap decks (three tap decks total). The vertical units are connected together by interphase shafts (two). One of the vertical decks is also connected to the external operating mechanism.This configuration is shown in Figure 10.Figure 10.Installation and MountingInspection Upon Receiving• Check for visible damage.• All DTL tap changers are shipped with moving contacts of all decks in the same position. Please check to verify that the moving contacts are indeed in the same position before continuing.• Verify that the shipment is complete and contains all compo- nents ordered.• Check that the type designation and shop order number agree with the delivery documents (i.e. the packing list or ABB’s ordering acknowledgement). The shop order number is stamped on the rating plate.Required Tools and MaterialsOnly standard tools are required.Pre-Installation Work Required by Customer• Make the appropriate size hole in the transformer tank according to the dimensions shown in the tap changer outline drawing.• Weld mounting boss (not supplied by ABB) to the transformer wall. This weld must be gas tight.• Prepare the superstructure with holes for the assembly of each DTL deck.The DTL is usually mounted vertically, parallel to the windings.The information that follows is intended for this type of installation.If some other orientation is being considered, please consult ABB.The type DTL tap changer requires a support structure constructed of appropriate insulating materials to secure the tap changer decks vertically. This structure, which is part of the transformer design,usually also supports the HV cleats and leads. Clearance must be provided for the tap changer shaft operating system that is lo-cated at the lower end of the deck frames.Refer to the DTL dimension drawings for complete mounting details.Installation of tap changer decks:1. Make sure that all decks are in the same position.2. Install the first deck with bolts of insulating material through the two mounting holes at the top and bottom ends.3. To mount the second deck, insert one bolt of insulating material at the top to loosely hold it in place.4. Install the operating shaft between the first and second decks as follows ( Figure 11):•Slide the end of the inter-phase shaft over the U-joint ball,lining up the holes in the switch shaft and the operating shaft.•Place the spring washer, shield washer and spacer over the bolt.•Insert the spacer and bolt through the slotted hole in the operating shaft and thread into the threaded hole in the switch shaft.•In the same manner, attach the shaft to the second deck.Figure 11.5. Repeat this process for the third deck.6. To confirm that the installation has been done correctly, turn the operating shaft and observe the movement of the bridging contacts. All three phases should move together smoothly from one end to the other.7. The operating shaft between the outside deck, left or right end depending on what was ordered, and the external operating mechanism is installed after the active part has been installed in the tank. This shaft is slotted to provide some flexibility in the length to compensate for the expan- sion and contraction of the transformer tank during operation.ABB78. For attachment of the drive shaft to the first deck, first slide the slotted drive shaft back to allow for aligning the drive shaft with the switch shaft, then slide the drive shaft over the switch shaft. Insert the spacer and bolt through the slotted hole in the operating shaft and thread into the threaded hole in the switch shaft.9. Connecting tap leads:•Cut tap leads to the correct length for connection to the appropriate tap changer terminal. Crimp the supplied connectors to the tap leads. Connect the tap leads to the correct tap changer terminal. The tap leads are connected to alternate sides of the switch ( See Figure 12)Installation TipTo ease the installation of the tap changer ABB recommends that the assembly technician build a replica of the tap changer and the connection points. This replica can be installed in the place of the tap changer, allowing the tap leads and insulation to be cut to the proper length and installed without risk of damaging the tap changer. After the tap leads have been fully assembled on the replica, undo the connectors, remove the replica and then install the tap changer in its place.External Mounting BossAn external mounting boss must be fabricated and welded to the transformer tank in order to seat the operating mechanism.Processing TemperaturesT he type DTL tap changer is designed to operate properly in the transformer environment. However, the transformer manufacturer must not thermally over-stress the tap changer during transformer manufacturing and processing. The maximum temperature that the DTL tap changer can be exposed to during transformer manu-facturing is 125°C. If the tap changer will be exposed to tempera-tures greater than 125°C during manufacture, ABB should be consulted for technical guidance. Processing within the tempera-ture range of 105°C to 125°C should not exceed 48 hours total exposure time.Renewal PartsIf renewal parts are required, order them through the nearest ABB Inc. representative. Please provide the item description and the identification numbers (model, style, catalog).RepairsIn normal use, the DTL tap changer will not require repairs. We recommend that the transformer manufacturer be contacted before any repairs are made.MaintenanceABB de-energized tap changers require little or no mainte-nance to ensure proper mechanical and electrical operation of the switch. The transformer should be de-energized before operating the tap changer. The external operating mechanism should be inspected for any damage and gears should be lubricated to ensure proper operation. Operate the tap changer across its full range a minimum of twenty times to assure proper mechanical operation and cleaning of the contacts. The above should be performed if the position of the switch is changed for any reason.W A R N I N GBEFORE ATTEMPTING ANY DIS AS SEMBLY OR RE-PAIRS, DE-ENERGIZE THE TRANSFORMER AND THE AUXILIARY POWER S OURCE. FAILURE TO DO S O COULD RES ULT IN PERS ONAL INJURY, PROPERTY DAMAGE, OR DEATH.Technical SupportIf a technical question arises regarding the product detailed in this Technical Product Literature contact customer service at the address below.CommentsABB Inc. continually strives to make its instruction literature current, accurate, and easy to understand.

General safety instructions WARNING! All electrical installation and maintenance work on the drive should be carried out by qualified electricians. The drive and adjoining equipment must be properly earthed. Do not attempt any work on a powered drive. After switching off the mains, always allow the intermediate circuit capacitors 5 minutes to discharge before working on the frequency converter, the motor or the motor cable. It is good practice to check (with a voltage indicating instrument) that the drive is in fact discharged before beginning work. The motor cable terminals of the drive are at a dangerously high voltage when mains power is applied, regardless of motor operation. There can be dangerous voltages inside the drive from external control circuits even when the drive mains power is shut off. Exercise appropriate care when working on the unit. Neglecting these instructions can cause physical injury or death.
埃斯顿伺服电机技术解答
伺服电机技术解答三相交流永磁同步伺服电机简称交流伺服电机（AC server motor)或伺服电机，由于它具有高响应、高精度、运行平稳、恒转矩输出、能过载、低噪声、结构简介、可靠性高、免维护等优点，是目前旋转电机中最佳的控制电机。
本章以EDB驱动器和其配套伺服电机为例，简述伺服电机在应用中的有关问题及注意事宜，其原则和方法同样适用于其它型号的驱动器配伺服电机。
伺服电机选型：伺服电机的选型是多个因素综合考虑、合理选择的过程，一般应着重注意这几个参数的选择：电机的额定转矩、电机运行的最高转速、负载惯量及电机转子惯量、加减速时所需要的过载能力、电机起停频率等。
通过机械传动机构加在电机上的负载有二种，即负载转矩和负载惯量。
负载转矩如由下图运动方式形成：则：图中Ta为因加速时间t1形成的加速转矩，Tb为由于减速时间t3形成的制动转矩，Tf 为在t2时间内产生的负载转矩，T0为在停止时间t4产生的锁定转矩，n为工作时电机的转速。
Ta、Tb、Tf、T0、n均为通过机械传动装置折算到电机轴上的参数。
Ta、Tb可参见下式确定：式中：Jm—电机转子惯量（），Jl—折算到电机轴上的负载惯量（），t单位：sec，n单位：rpm，Ta、Tf单位：Nm。
由下式确定一个周期电机转矩的均方根值：确定预选电机的额定转矩大于Trms值；确定预选电机的额定转速大于实际运行的最高转转速；其过载转矩大于Ta、Tb中最大值，即可选定伺服电机。
加在电机轴上的负载惯量，对伺服电机的灵敏度及快速移动、精确定位有很大的影响。
较大的负载惯量，当指令速度发生变化时，电机达到指令速度的时间会较长；多轴同时运动时，会使形成的轨迹偏离指令轨迹过大，造成较大的误差。
所以，选择机械传动机械，使折算到电机轴上的负载惯量合适，是伺服电机选型中重要的过程。
机械传动不仅要满足脉冲当量、转矩（功率）放大等技术要求，更要注重负载惯量与电机的适配。
负载惯量是否与电机相适配的标准，是指负载惯量折算到电机轴上的负载惯量Jl，其数值与电机转子惯量的倍数关系。
旋转变压器(resolver)原理教学资料
旋转变压器( r e s o l v e r ) 原理§4—1旋转变压器旋转变压器是一种常用的转角检测元件，由于它结构简单，工作可靠，且其精度能满足一般的检测要求，因此被广泛应用在数控机床上。
一、旋转变压器的结构旋转变压器的结构和两相绕线式异步电机的结构相似，可分为定子和转子两大部分。
定子和转子的铁心由铁镍软磁合金或硅钢薄板冲成的槽状心片叠成。
它们的绕组分别嵌入各自的槽状铁心内。
定子绕组通过固定在壳体上的接线柱直接引出。
转子绕组有两种不同的引出方式。
根据转子绕组两种不同的引出方式，旋转变压器分为有刷式和无刷式两种结构形式。
图4-1是有刷式旋转变压器。
它的转子绕组通过滑环和电刷直接引出，其特点是结构简单，体积小，但因电刷与滑环是机械滑动接触的，所以旋转变压器的可靠性差，寿命也较短。
图4-1有刷式旋转变压器图4-2无刷式旋转变压器图4—2是无刷式旋转变压器。
它分为两大部分，即旋转变压器本体和附加变 压器。
附加变压器的原、副边铁心及其线圈均成环形，分别固定于转子轴和壳体 上，径向留有一定的间隙。
旋转变压器本体的转子绕组与附加变压器原边线圈连在 一起，在附加变压器原边线圈中的电信号，即转子绕组中的电信号，通过电磁耦 合，经附加变压器副边线圈间接地送出去。
这种结构避免了电刷与滑环之间的不良 接触造成的影响，提高了旋转变压器的可靠性及使用寿命，但其体积、质量、成本 均有所增加。
常见的旋转变压器一般有两极绕组和四极绕组两种结构形式。
两极绕组旋转变 压器的定子和转子各有一对磁极，四极绕组则有两对磁极，主要用于高精度的检测 系统。
除此之外，还有多极式旋转变压器，用于高精度绝对式检测系统。
旋转变压器的工作原理由于旋转变压器在结构上保证了其定子和转子 （旋转一周）之间空气间隙内磁通 分布符合正弦规律，因此，当激磁电压加到定子绕组时，通过电磁耦合，转子绕组 便产生感应电势。
图4—3为两极旋转变压器电气工作原理图。
