施耐德低压电气考试考试答案（题库版）1、问答题选择电涌器要遵循哪些步骤？正确答案：根据当地雷暴日天数、建筑物类型、建筑物有否接闪器和对供电连续性要求的高低确定电涌保护器所需达到的最大放电电流Imax（江南博哥）。

对有接闪器的建筑物，其雷电冲击电流形成的辐射电磁场可在闭合回路中产生过电压，此时应在进线处安装Imax=60KA（10/350微秒）的PRF1电涌保护器。

根据被保护设备的Uchoe确定电涌器的Up。

确定被保护回路类型（1P、1P+N、3P、3P+N）及其接地系统类型（TT、TN-S、TN-C、IT）确定配电网络的Us.max和电涌器的Uc。

根据基本原则Us.max<up<uchoe对照电涌器的参数表选定电涌器。

br="">在PRF1和二级电涌保护器之间串联一LA40解藕器，以实现PRF1和低残压电涌保护器的保护动作配合。

2、问答题要求NS断路器完成远方监控测量功能时，如何选配和联接Digipact元件？正确答案：需做如下配置：NS400630断路器需配置带COM通讯功能的电子脱扣器STR53UE或STR43ME（NS100250断路器无此项）；断路器根据所需要传输的状态量可以选择配置标准辅助接点OF、SD、SDE、SDV、CD、CE；断路器根据控制要求选配标准的电动操作机构；每台断路器配一台指示与控制接口SC150；以上三项与SC150联接。

PM150电力参数测量仪。

多台断路器（具体数量要求参见问题4.7）共用一台数据集中器DC150，每台SC150和PM150通过内部总线与DC150联接，DC150通过Modbus/Jbus总线与PC 机、PLC通讯。

另外，CompactNS断路器可以选配带通讯功能的辅助接点和电动机构，此时它们直接通过内部总线与DC150联接，不再与SC150联接。

这种配置方案尤其适用于NS100250断路器。

当电力参数测量仪选用PM300时，PM300表不通过内部总线与DC150联接，其直接通过MODBUS/JBUS通讯总线向监视器或PLC传输数据。

有源电力滤波器(APF)品牌排行
当前，市场上生产有源电力滤波器的厂家很多，各个品牌参差不齐，且国家标准未正式出台，所以只能挑选出一些市场上一些主流的APF品牌，从质量、稳定性各方面介绍一下当前市场上主流有源电力滤波器品牌的市场情况：
合资主流品牌：霍尼韦尔、GE、诺基亚、ABB、施耐德、
传统的电气行业的几大合资品牌从稳定性、可靠性来说都依然是值得可靠信赖，但是技术参数比得上国内品牌，国内品牌因为竞争的缘故一味追求性能参数，产品稳定性大打折扣，合资品牌的价格都相对较高，一般市场标价达2000~4000元/A。

传统的合资品牌西门子貌似还没有APF。

国产一线品牌：南京亚派麦克斯韦电气深圳盛弘上海思源赛博电气深圳英纳仕追日电气........数百家品牌
估计国内生产APF的厂家有上百家，以上品牌都是最近2年广告比较多的品牌，推广力度比较大而已。

但是参差不齐。

国产品牌的通病就是质量不稳定，国产品牌没有7年以上的应用案例，价格也不一定便宜，国产品牌的价格一般是合资的50%~100%。

有源电力滤波器的核心器件比如IGBT、电容器、CPU等国内电子元件技术都不稳定，所以国内生产APF 的厂家大多依靠进口国外品牌的核心元器件，然后再在国内组装，所以成本总体也不低，主要是人工成本较低。

另外国产有源电力滤波器的通病就是并联技术，IGBT并联技术还不过关。

但是未来的趋势肯定是核心器件国产化后，国内APF厂家的价格也许才会真正降到很低。

另外，有源电力滤波器出来10年左右，市场上有部分打着国外欧美公司品牌(如意大利、美国)的旗号，游龙混杂，有些品牌名字看着大气，实际上是国内生产的，满足国内市场扬眉崇外的心理，所以要注意辨别。

It is preferable to store the unit in its original shipping container to protect the unit from potential damage.2. SAFETY PRECAUTIONS This chapter contains important safety precautions that must be followedbefore attempting to install, service, or maintain electrical equipment. Carefullyread and follow the safety precautions outlined below.3. INSTALLATION3.1 General3.2 Location and Mounting 3.2.1 Enclosed Units This section provides the information required to properly install AccuSine PCS and associated equipment for proper operation and performance. Frequently start-up difficulties are the result of incorrect wiring. Every precaution must be taken to assure that the wiring is done as instructed. Read and understand all instructions in this section prior to installation.Note:• AccuSine PCS may not perform properly if power-factor correction capacitors are connected to the AC-bus down-stream from theAccuSine PCS current transformers (CT’s). Consult Section 3.5 inthis manual to properly deal with this situation. In addition to stand-alone connection, power factor capacitors may be enclosed inequipment. Refer to site one-line diagrams/equipment schematics toverify their absence. Consult Square D if in doubt.• The following information is a guide for proper installation. Square D Company does not assume responsibility for compliance with anycode, national, local or otherwise, or for the proper installation of thisequipment. Personal injury and/or equipment damage may result ifcodes and instructions are ignored during installationThe AccuSine PCS unit must be mounted in a vertical position on a smooth, non-flammable surface using the mounting holes provided. Refer to Figures 3-1,3-2 and 3-3 for mounting dimensions and location of mounting holes. Lifting lugs are provided for hoisting. Mount in a clean, dry location with an ambient temperature between 00C (320F) and 400C (1040F) and with a humidity not greater than 95%, non-condensing.3.2.2 Chassis UnitsChassis -type AccuSine PCS units must be installed in a NEMA-rated enclosure such as a motor-control center. For optimal cooling the chassis must be mounted in a vertical position using the mounting holes provided. See Figures 3-4, 3-5 and 3-6 for mounting dimensions and position of mounting holes. Chassis -mount units may be mounted directly side-by-side. The remote Digital Interface Module (DIM) including its connecting cable are optional for chassis-type AccuSine PCS units and must be ordered and installed separately if a DIM is required. Refer to Appendix A, Specifications, for model numbers. The DIM should not be installed in close vicinity to a heat-source, power-wiring, or high-power switching elements. The cable-assembly connecting the DIM to J3 and J4 of the Control PCB must not be routed in parallel with or attached to power-wiring.Figure 3-1: 50A, NEMA1 Dimensional DrawingAll dimensions in inches [mm]Figure 3-2: 100A, NEMA1 Dimensional DrawingAll dimensions in inches [mm] Lifting lugs Lifting lugs Mounting holesLifting lugsAll dimensions in inches [mm]3/8" (10mm) mountinghardware recommended All dimensions in inches [mm]3/8" (10mm) mountinghardware recommended All dimensions in inches [mm]All dimensions in inches [mm]3.3 Power and Ground Connections3.3.1 Connecting AccuSine PCS3.3.2 Circuit Breaker andManual Disconnect Selection 3.3.3 Conduit Routing Figure 3-7 shows four possible ways to connect AccuSine PCS within a power system. However, almost every individual installation will be somewhat different.AccuSine PCS may not perform properly if power-factor correction capacitors are connected to the AC-bus down-stream from the AccuSine PCS current transformers (CT’s). Consult Section 3.5 in this manual to properly deal with this situation. In addition to stand-alone connection, power factor capacitors may be enclosed in equipment. Refer to site one-line diagrams/equipment schematics to verify their absence. Consult Square D if in doubt.For all configurations the following points must be observed:• The phase sequence of the 3-phase power wires feeding the AccuSine PCS must be positive sequence, i.e. a phase rotationmeter should indicate “clockwise”.• DC-drives must have a 3-phase AC reactor (3% minimum) or a drive isolation transformer inserted between the AccuSine PCS connection point and the drive AC input.• Variable-frequency AC-drives must have a 3-phase AC reactor (3% minimum) or a drive isolation transformer with electro-static shielding inserted between the AccuSine PCS connection point and the drive AC-input, unless the drive is a PWM type drive with a diode rectifier and has a DC-bus reactor incorporated. In that case AccuSine PCS may beconnected directly to the drive AC input terminals.• A third CT (current transformer) is required if single– or three-phase line-to-neutral connected loads are present downstream from the chosen location of the two CT’s needed by the Accusine PCS unit.An external circuit breaker or manual disconnect is required as an isolation device. Per NEC, this circuit breaker must be rated for at least 125% of the rated load current. A circuit breaker/manual disconnect rated at no less than 65Amps is suggested for the 50Amp AccuSine PCS, 125 Amps for the100Amp AccuSine PCS, and 400Amps for the 300Amp AccuSine PCS.Note: Local codes and regulations must be checked to ensure compliance.Power cables connected to AccuSine PCS must be placed in metal conduit to reduce noise coupling. Entry for all power and control wiring has to be made through the removable conduit-entry plates on the bottom or top of the AccuSine PCS enclosure (see Figures 3.1,3-2 and 3-3). In accordance with NEC rules, metal conduit has to be grounded to the AccuSine PCS ground-terminal located adjacent to the main fuses.Instrumentation and CT wiring has to be routed in a separate grounded metal conduit. Per NEC, sizing of the conduit depends on the selected wire size (See Section 3.3.4)Utility transformer or Upstream panel Accu - Sine PCS Distribution Panel or Motor Control Center Load CT Location Load Other Loads Other Loads Harmonic cancellation and/or power -- factor correction of a selected load on panel Utility transformer or Upstream panel Accu - Sine PCS Distribution Panel or Motor Control Center Source CT Location Corrected Load Corrected Load Corrected Load Harmonic cancellation and/or power - factor correction of all loads on panel Three possible Utility transformer or Upstream panel Accu - Sine PCS Distribution Panel or Motor Control Center Source or Load CT Location Other Loads Other Loads Corrected Load Less than 25 feet per NEC 240 - 21 CT locations shown Utility transformer or Upstream panel Accu - Sine PCS Distribution Panel or Motor Control Center Source or Load CT Location Other Loads Other Loads Corrected Load Junction Box Breaker or fused disconnect Four possible CT locations shown More than 25 feet per NEC 240 - 213.3.4 Power and Ground Wire Selection 3.3.4.1 50 & 100A Wire SelectionUsed as a harmonic current compensation device, AccuSine PCS producescurrents at frequencies that are multiples of the AC line fundamentalfrequency. To avoid excessive heating, power cables, as well as inputdisconnect devices, should be properly rated to carry these currents whileaccounting for any skin effect resistance increase of these higher frequencies.Note:Local codes and regulations must be checked to ensure compliance.Accusine PCS has regulatory approval for use with copper wire only(rated 75 deg. C or higher)Table 3-1: Wire Derating Factors (50 & 100A models)Table 3-2 lists the range of acceptable wire gauges and the required torque forthe power terminations for the 50 Amp and 100 Amp AccuSine PCS model: Table 3-2: Wire sizes and Terminal Torque (50 & 100A models)A dedicated ground conductor must be used. Per NEC, its size depends onthe selected power cable. An 8 AWG (10mm2) THHN copper ground wire isrecommended for the 50 Amp unit, whereas a 4 AWG (25mm2) THHN copperground wire should be used for the 100 Amp unit.All power wiring has to be routed directly from the conduit entry plate to theterminations on fuse-block FB1 (and the earth grounding terminal) withoutloops.Wire Size(AWG|mm2)3|N/A 2|35 1|N/A 1/0|50 2/0|N/A3/0|74/0|N/ADiameter (DIA)in inches (mm)0.260(6.6)0.292(7.4)0.332(8.4)0.373(9.5)0.419(10.6)0.470(11.9)0.528(13.4)Wire DeratingFactor1.00 0.99 0.98 0.95 0.93 0.89 0.86AccuSine Model Wire Size Rangein AWG|mm2Required Terminal Torquein lbs.-in.

When using copper wire, no de-rating is needed for wire sizes smaller than 3AWG. For copper wire sizes larger than3AWG, Tables 3-1 and 3-3 list de-rating factors.3.3.4.2 300A Model Wire SelectionTable 3-3: Wire Derating Factors (300A models) Note: AccuSine PCS has regulatory approval for use with copper wire (rated 75 deg. C or higher) only. Paralleling of conductors is another option to avoid this de-rating penalty. For general guidelines on employing conductors in parallel, refer to NEC. The 300 Amp AccuSine PCS model has been designed for paralleled power cables only. If only one single conduit is being used, 250 MCM (120 mm 2) cable must be used (2 conductors/phase, 75 deg. C min.). If two conduits are being used, 4/0 AWG (95 mm 2) cable (2 conductors/phase, 75 deg. C min.) is adequate. A dedicated ground conductor must be used. Per NEC, its size depends on the selected power cable. A 1 AWG (50 mm 2) THHN copper ground wire is recommended for the 300 Amp rated unit. All power wiring has to be routed directly from the conduit entry plate to the bus-bar terminations (and the ground terminal) without loops. The terminal bus-bars are designed to accept 3/8” SAE Grade 5 (M10) bolts. The recommended fastener torque is 300 lbs.-in. (33.9 Nm).

They may be used to power indicating lights or other low power control circuits. Each contact is an isolated, dry contact rated at120/240 VAC and 1 Amp.Table 3-4 shows the pin layout (1 – 12) of the user output contacts located on J2 of the AccuSine PCS Control.“C” means common terminal, “NO” means normally open, “NC” means normally closed. See section 6.2 for contact operation details.AccuSine requires two (2) external current transformers (CT’s) to measure the load current waveforms. Standard CT’s rated for 400 Hz (accuracy better than 3%) can be used. AccuSine can be readily configured for CT’s rated at 500A, 1000A, 3000A, and 5000A. The output rating for any of these CT’s must be 5 amperes. Three (3) external CT’s are required if line-to-neutral connected loads (4-wire systems) are included.CT’s must be selected for:1) The maximum load current through the conductor on which they areinstalled with an output rating of 5 Amp.2) The maximum burden (in VA) on the CT formed by the CT wiring and theAccuSine burden (Note: AccuSine burden is 2.5 VA, or 0.1 Ohms).3) The inside dimensions of the CT must exceed the dimensions of theconductor arrangement on which the current transformers are to beplaced.The CT's have to be mounted on phases A and B (and C, if required for 4-wire systems) with the orientation arrow pointing toward the load. CT's may be installed on the source side or on the load side of the AccuSine power connection, see Figures 3-11 and 6-2, Chap. 6-2., and Chap.5.3.3. for proper setup. See Table 3-6 for maximum allowable CT-wire lengths. Do not allow the conductor on which the CT is mounted to be lodged in the joint-area of a split-core CT because inaccurate operation of the filter will result.Refer to Appendix B for details on the CT’s which Square D provides for use with AccuSine PCS.Note: AccuSine PCS will not function properly if power-factorcorrection capacitors are connected to the bus downstream from theCT's. These capacitors may be part of existing equipment or connected separately. For proper functioning of the AccuSine PCS, the CT’s need to be inserted downstream of these capacitors. However, if the CT’s are needed to be inserted upstream of the capacitors, then the signals from these CT’s are to be added with signals of additional CT’s measuring the capacitor currents with the orientation arrows pointing toward the loadTable 3-4: Dry Contact LayoutPower On Run Fault At Max.

CT wiring must be routed in a separate metal conduit. Per NEC, this conduit must be grounded to the AccuSine PCS ground terminal. CT-wiring and wiring connected to J2 must be routed directly from the conduit entry-plate to TB1 (and J2 of the Control PCB). Terminal X1 of the Phase A CT is connected to terminal 1 of TB1, terminal X2 is connected to terminal 2. Terminal X1 of the Phase B CT is connected to terminal 3 of TB1, terminal X2 is connected to terminal 4. Terminal X1 of the Phase C CT (if required) is connected to terminal 5 of TB1, terminal X2 is connected to terminal 6. Terminate shields on one of the terminals marked “earth ground” on TB1.Note: Do not connect any additional burden for other measurement purposes into the secondary circuit of the current transformers. Use an additional, separate current transformer if such measurements are required.If the total harmonic current exceeds the rating of a single AccuSine PCS, up to a maximum of 5 parallel units can be installed using the same set of or more sets of current transformers (CT's), provided that the same CT ratio is selected.The number of units operating in parallel using the same set or multiple sets of CT’s on the same location has to be entered via the Digital Interface Module (See Chapter 5.3.3 and Table 5-2). In parallel operation, the total current supplied is divided amongst the units as an equal percentage of its rating.Each AccuSine PCS includes on terminal block TB1 terminals for interconnection to TB1 of another AccuSine PCS unit, see Figure 3-12.The primary unit is the unit receiving the CT secondaries on TB1, terminals 1, 2, 3, 4, 5, and 6. From this unit, TB1 terminals 7, 8, 9, 10, 11, and 12 are connected to TB1 terminals 1, 2, 3, 4, 5 and 6 of the next unit. Each additional unit is connected in the same manner. Observe the wiring diagram of Figure 3-12 and Table 3-6 for maximum allowable cable-length and wire gauge. The interconnection requires two (three if C phase requires a CT) shielded twisted-pair cables. Each wire pair carries up to 5 Amps current rated at not more than 10 volts.Note: On the last unit in the loop, terminals 7-13 on TB1 should already have been shorted by jumpers in the factory. Do not remove these shorting jumpers.Figure 3-12: Multiple Unit Interconnect CT WiringUsing shielded twisted-pair cable make the following connections on the terminal block TB1 of the primary unit (the unit which is connected to the current transformer) and TB1 of the secondary unit (see Figure 3-12). Note:Connect shields to one of the TB1 terminals marked “earth ground” of the primary unit only. Do not connect shields to ground of secondary unit.Table 3-5: CT Wiring for Multiple Unit OperationPrimary Unit Secondary Unit Pin 7 Pin 1 Connect First Pair (for phase A) Pin 8 Pin 2 Pin 9 Pin 3 Connect Second Pair (for phase B) Pin 10 Pin 4 Pin 11 Pin 5 Connect Third Pair (for phase C) (If required for 4-wire system) Pin 12 Pin 6 wire systemsNote:q If AccuSine PCS units are connected in parallel, 1000, 3000 and 5000Amp current transformers (CT) with CT ratio’s of respectively 1000:5, 3000:5 and 5000:5 are required.q The preferred method of operation for paralleled units is with the CT’slocated on the “Load-Side” or downstream of the AccuSine PCS units. When it is desired to place the CT’s on the “Source-Side” or upstream of the AccuSine PCS units, then for this case:• units connected in parallel (restricted to 5) must have the same set ofCT’s,• observe the additional CT-requirements of Appendix C: Multiple UnitOperation with source-side connected CT’s.The CT’s have a limited output-VA. Therefore, it is imperative to observe the following wire-length limits (maximum total loop-length between the CT’s and all AccuSine PCS units in line). In the following Table 3-6, the wire lengths for the different wire sizes are specified for the case that the output-VA is 10 VA. As indicated also in Table 3-6, different CT’s have different output-VA. If a CT is selected with an output-VA differing from 10, then the wire length limits specified in the table have to be multiplied by a factor equal to one-tenth of the output-VA of the selected CT. For example, the choice of using the 5000:5 CT leads to the need to multiply the wire length limits as specified in Table 3-6 by a factor of 4.5.Table 3-6: CT Wire length limitsMaximum CT-wire length for 10 output-VA(ft | m)Number of parallel units on same CT12 318 | 0.7519 | 5.7812 | 3.656 | 1.82 16 | 1.530 | 9.1220 | 6.08 10 | 3.04 14 | 2.548 | 14.6032 | 9.73 16 | 4.86 12 | 477 | 23.4152 | 15.8125 | 7.60Wire Gauge(AWG|mm 2)10 | 6248 | 75.39165 | 50.1683 | 25.23Note : For 500:5 CT, output-VA = 3. Thus, multiply lengths in table above by 0.3 For 1000:5 CT, output-VA = 10. Thus, lengths as indicated in table applyFor 3000:5 and 5000:5 CT’s, output-VA = 45. Thus multiply lengths in table above by 4.54. START-UP 4.1 General4.2 Installation Inspection4.3 Digital Interface Module (DIM)This section provides the sequence of steps required to start-up AccuSine PCS. Before applying power read and understand this information thoroughly.Be sure the input voltage matches the voltage rating of the unit installed. Inspect all connections for both power and control wiring. Insure that the correct termination points have been made for each wire. Insure that all connections are firmly tight prior to start-up.The DIM is located on the front of the enclosure. See Figure 5-1. Note that for chassis-type units the DIM and its connection cable are optional and have to be ordered and mounted separately.The pre-charge contactor activates within 3 seconds after application of AC power. The DIM will initialize within approximately 3 seconds. Refer to Chapter 5 for operating AccuSine PCS.Note: If a 'Fault' message appears on the screen upon application of AC power, do not attempt to operate AccuSine PCS. Refer to Table 7-6 for fault diagnosis.5. DIGITAL INTERFACE MODULE5.1 General5.2 Keypad Functions The information provided in this chapter describes the various controls and indicators contained in the DIM. Read the entire chapter before proceeding. Operation is with simple keystrokes. The DIM is used to access parameters and read status and warning codes. The commands entered through the keypad are seen on the display.The full DIM is displayed on the next page.Individual keys control functions as follows:RUN - Starts the AccuSine PCS. A green LED lightsup to indicate “RUN“-state. (Touchpad color: Green)STOP - Stops the AccuSine PCS. Run light isextinguished when “STOP” is depressed.(Touchpad color: Red)SETUP - Selects the SETUP mode to changeparameters.ADJUST - Moves the cursor up or down by one lineat a time. The cursor cycles back to the firstparameter at the end of the list.ENTER - Selects the parameter to adjust in theSETUP mode.
