DescriptionThe Ag8000 series of modules are designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af Power-over-Ethernet (PoE) standard.IEEE 802.3af allows for two power options for Category 5 cables and the Ag8000 series have two pairs of power inputs pins: - VA1&2 and VB1&2 to accommodate this, see Figure 1.The Ag8000 signature and control circuit provides the PoE compatibility signature and power classification required by the Power Sourcing Equipment (PSE) before applying up to 15W power to the port. The Ag8000 is compatible with Class 0 to Class 3 equipment.The high efficiency DC/DC converter operates over a wide input voltage range and provides a non-isolated regulated low ripple and low noise output. The DC/DC converter also has built-in output overload, output short-circuit and over-temperature protection.PbV1.3 July 2006 Ag8000 Data Sheet Power-Over-Ethernet ModuleTable of Contents1.

The output voltage can be adjusted from isnominal value, by connecting an external resistor from this pin toeither the +VDC pin or the -VDC pin. 10 IC Internal Connection. Do not connect to this pin.5. Functional Description5.1. InputsThe Ag8000 has two internal bridge rectifiers (see Figure 1: Block Diagram) connected to the VA1-VA2and the VB1-VB2inputs. This allows the Ag8000 to be compatible with equipment that use the different power options, see Figure 3: Typical System Diagram. It is important that the PSE does not apply power to the VA and VB outputs at the same time (Refer to IEEE802.3af for more information).Figure 3: Typical System Diagram5.2. PD SignatureWhen the Ag8000 is connected to the Cat 5e cable, it will automatically present a Powered Device (PD) signature to the Power Sourcing Equipment (PSE) or Midspan Equipment, when requested. The equipment will then recognise that a powered device is connected to that line and supply power.5.3. IsolationThe Ag8000 series conforms to the IEEE 802.3af standard except for the 1500V isolation, which must be done externally. This is usually achieved without additional components, contact Silver Telecom for further details.5.4. Power ClassificationThis is optional from the PSE and is used for power management. The Ag8000 allows the current class to be externally programmed by connecting a resistor between the CP1 and CP2 pins, see Figure 4: Class Programming Option. If no resistor is fitted the Ag8000 will default to Class 0, a full list of programming resistor values are shown in Table 2: Class Programming.CLASSProgrammingResistance (Ohms)Min Power(W)Max Power(W)0 Do not fit 0.44 12.951 698 0.443.842 383 3.846.493 243 6.4912.954 TBD ReservedReservedTable 2: Class ProgrammingFigure 4: Class Programming Option5.5. DC/DC ConverterThe Ag8000’s DC/DC converter provides a non-isolated regulated low ripple and low noise output, that has built-in overload and short-circuit output protection, as well a built-in thermal cut-off - see Table 1: Ordering Information for voltage and power ratings.Because the Ag8000 series is non-isolated the +VDC output is connected to the positive input through a diode bridge.5.6. GroundingIf the Ag8000 is supplied from a grounded source (e.g. a standard multi-channel PSE) it is important that the –VDC output is NOT connected to ground.Connecting both input and output to ground will short circuit the input diode bridge, this prevents correct operation of the Ag8000.5.7. Output AdjustmentThe Ag8000 has an ADJ pin, which allows the output voltage to be increased or decreasedfrom its nominal value.Figure 5: Output Adjustment shows how the ADJ pin is connected: -Figure 5: Output AdjustmentReducing the output voltage, connect R between ADJ and -VDCValue of R Ag8003 output Ag8005 output Ag8012 outputOpen Circuit 3.3V 5.0V 12.0V15K 3.0V 4.3V 9.0V0 Ohms 2.5V 2.5V 7.5VIncreasing the output voltage, connect R between ADJ and +VDCValue of R Ag8003 output Ag8005 output Ag8012 outputOpen Circuit 3.3V 5.0V 12.0V15K 3.5V 5.3V 12.5V0 Ohms 4.5V 7.5V 13.0VTable 3: Output Adjustment Resistor (R) Value*Note: the results in Table 3 are under minimum load conditions5.8. Typical ConnectionsThe Ag8000 only requires one external component as shown in Figure 6: Typical Connection Diagram, a minimum of 470µF is recommended.The value of C1 will be related to the maximum load step change that the output needs to drive. For example, in an application were the output needs to cope with a 1.8 Amp load step change, a minimum of 1000µF should be used. This can be a standard low cost electrolytic and does not need to be a low ESR type.Figure 6 shows a 16V capacitor that would cover all product variants up to and including the Ag8012, see Table 1: Ordering Information.The Class programming and the Output Adjust inputs are optional and are provided to give great flexibility to the Ag8000 product range. Further information on using these inputs can be found in sections 5.4. Power Classification and 5.7. Output Adjustment.Figure 6: Typical Connection Diagram6. Typical ApplicationThe Ag8000 can be used in numerous applications. In the example shown in Figure 7: Typical Application, the data outputs from the switch are connected to the inputs of a midspan. The midspan will then add power (to the data) on each output that supports Power over Ethernet (PoE).In this example port 1 is connected to an ethernet camera and port 2 is connected to a wireless access point, both of these devices have a built-in Ag8000. When the midspan is switched on (or when the device is connected), the midspan will check each output for a PoE signature. On ports 1 and 2 the Ag8000 will identify themselves as PoE enabled devices and the midspan will supply both data and power to these peripherals.The other ports (shown in this example) will not have a PoE signature and the midspan will only pass the data through to these peripherals. The midspan will continuously monitor each output to see if a PoE enabled device has been added or removed.Figure 7: Typical Application7. Typical RecommendationsFigure 8: Typical Layout gives an example of the tracking needed for the Ag8000. R1, R2 and R3 are optional components, but C1 needs to be positioned close to the output pins of the Ag8000 as possible to minimise the current loop. The thermal performance of the Ag8000 can be improved by increasing the surface area of the output tracks (+VDC and -VDC) this is not applicable if the Ag8000 is in a socket.Figure 8: Typical Layout8. Operating Temperature RangeBecause the Ag8000 is a power component, it will generate heat, so it is important that this be taken into consideration at the design stage.The heart of the Ag8000 is a DC/DC converter, which like any other power supply will generate heat. The amount of heat generated by the module will depend on the load it is required to drive and the input voltage supplied by the PSE. The information shown within this section of datasheet is referenced to a nominal 48Vdc input voltage supplied by the PSE.The Ag8000 has a maximum ambient operating temperature of 70O C see Figure 10, Figure 11 & Figure 12. These results are in still air without any heatsinking, the performance of the Ag8000 can be improved by forcing the airflow over the part or by using a heatsink (see the Ag8000 application note on heatsinking for more information).The output stage of the Ag8000 has a built-in thermal protection circuit, to prevent the module from being damaged if operated beyond its power / temperature specification.Because each application is different it is impossible to give fixed and absolute thermal recommendations. However it is important that any enclosure used has sufficient ventilation for the Ag8000 and a direct airflow if possible.One simple method for drawing some of the heat away from the Ag8000 is shown in Figure 9. Power planes connected to the +VDC and GND pins of the Ag8000 can be used to draw heat away from the DC/DC converter via the output pins.These power planes must be on the outer layers of the PCB and the Ag8000 must not be fitted into a socket (this example is suitable for both –S and –D variants).Figure 9: Power Plane Heatsink for Ag8000 (-S or -D)Figure 10, Figure 11 & Figure 12 show the maximum ambient temperature under different load conditions. These figure have been recorded in a sealed enclosure (in still air) using a heater element to elevate the ambient temperature (within the enclosure).-20-1001020304050607014253O u t p u t P o w e r (W )Ambient Temperaure (°C)Figure 10: Ag8003 Operating Profile-20-1001020304050607014253O u t p u t P o w e r (W )Ambient Temperaure (°C)6Figure 11: Ag8005 Operating Profile-20-1001020304050607014253O u t p u t P o w e r (W )Ambient Temperaure (°C)6789101112Figure 12: Ag8012 Operating Profile9.

警告：操作或修理本泵前，没有阅读使用说明书和采取 适当安全防范，可能会引起严重的伤害。
1 概述
1.1 概要
LG系列螺杆真空泵是一种干式运行，无接触，等螺距的螺杆型真空泵。它的
工作原理，是利用两个相平行的等螺距螺杆，在泵腔中作同步高速反向旋转而产
生吸气和排气作用。两螺杆经过精细动平衡处理，由轴承支撑，安装在泵壳中，
从泵的内表面上清理下来。当抽有腐蚀性的或有毒的气体，或像树脂一样有粘性
的材料时，本操作就显得尤其重要。
泵蒸汽冲洗：
当泵每次工艺过程结束后，关闭进气口主阀，无负载运行真空泵10-20分钟（干
运行，清洗净化）。本操作是消除或清洗在抽气过程中积聚在泵腔内的工艺气体
或可凝性蒸汽。这些残留在泵腔内的工艺材料是导致泵重新起动时发生过载的罪
本型泵采用了等螺距的螺杆型线，在螺杆的末端有内部压缩设计，即绝大部 分的压缩工作时在气体与排气口相通的时候完成的，也就是泵排出的最后阶段。 图3显示的是螺杆泵的P-V图表：（a）无内压缩；（b）最后阶段有压缩。PV图表 中显示的几个面积与泵吸取的能量成正比的。很明显地，采取适当的内压缩，有 利于降低功率的消耗，同时也减少了发热量。

基于高压输电线路节能导线选型的研究
基于高压输电线路节能导线选型的研究发布时间：2022-09-14T06:28:28.370Z 来源：《中国电业与能源》2022年5月9期作者：陈启正[导读] 随着国家节能减排产业政策的推行，中国南方电网有限责任公司在电力基本建设过程中采用新技术、新材料、新工艺建设资源节约型、环境友好型的绿色输电线路日益受到重视。
陈启正深圳供电规划设计院有限公司广东，深圳518000摘要：随着国家节能减排产业政策的推行，中国南方电网有限责任公司在电力基本建设过程中采用新技术、新材料、新工艺建设资源节约型、环境友好型的绿色输电线路日益受到重视。
推行全寿命周期管理，将全寿命周期管理理念与方法应用到绿色输电线路设计和建设中是实现电网科学发展、和谐发展之路。
关键词：节能导线、绿色输电线路1节能导线的定义及类型1.1节能导线的定义与广泛采用的铝线导电率为61%IACS的钢芯铝绞线相比，在等外径（等总截面）条件下，直流电阻（20℃）更小的导线称之为节能导线。
1.2节能导线的类型近年来，国内陆续研制出多种新型节能导线和增容导线，其中增容导线虽然可以提高输送容量，但其电阻损耗非常大，使用起来非常不经济，故目前国内比较常见和最具有代表性的主要有钢芯高导电率硬铝绞线、铝合金芯铝绞线和中强度全铝合金绞线三种节能导线，该三种节能导线与常规钢芯铝绞线相比，铝（铝合金）导体材料性能不同，导电率有所差异，下面分别介绍其特点。
1.2.1钢芯高导电率硬铝绞线高导电率电工硬铝以多根镀锌钢线为芯，外部同心绞合多层导电率在61.5%IACS至63%IACS之间的硬铝线构成，与铝截面相同的普通钢芯铝绞线相比，铝线导电率的提高，可使导线整体直流电阻值降低，电能损耗减少。
1.2.2铝合金芯铝绞线铝合金（铝镁硅合金）的基体为电工硬铝，以多根导电率为52.5％IACS或53％IACS之间的硬铝线构成。
在等总截面的应用条件下，由于铝合金芯替代了基本无导电能力的钢芯，其直流电阻小于普通钢芯铝绞线，提高了导电能力。
