工厂变电所配电系统中英文翻译

1、河南理工大学万方科技学院电气与自动化工程系2014届毕业生英文文献专业： 电气工程及自动化班级：10电一 1班学号： 1016303085姓名：许永辉时间：年 月曰目录原文1.汉译英7原文距离企业附近往往有多条可用电源，可以根据电源的电压等级和距离企业的距离， 电价等多种因素考虑选用合适的电源来达到经济，可靠的目的。本次设计共提出两套方 案：方案1采用两个35Kv的电源供电。电源A, B各负荷一台35Kv变压器，其下一级 设有10Kv变压器。方案2采用两个10Kv的电源供电。电源C, D直接各负荷一台 10Kv变压器。根据供配电技术表 4-1中，4电源均符合输送功率和输送距离的要 求。方案一优

2、点是电价较低，但距离企业较远，线路损耗较大。又要用到多个不同级 的变压器，造成初投资和运行费较高。方案 2只用到10Kv变压器，电源距企业较近， 维修和运行简单。所以选择方案2。这种方案适合全厂需求，初投资和以后的运行费用 都比较低廉且可靠性相对较高。本企业无大型高压设备。所以综合3个指标，全厂供电系统电源选择方案采用方案2。变电所的主接线是实现电能输送和分配的一种电气接线，在变电所的主接线图中 将电线或电缆、电力变压器、母线、各种开关避雷器电容器等电气设备有序的连接起 来，只表示相对电气连接关系而不表示实际位置。通常用单线来表示三相系统。对变电所的主接线主要有以下几个基本要求：(1) 安全主

3、接线的设计应符合国家标准有关技术规范的要求，能充分保证人身和设备 的安全；(2) 可靠 应满足用电单位对供电可靠性的要求；(3) 灵活 能适应各种不同的运行方式，操作检修方便；(4) 经济 在满足以上的前提要求下，主接线设计应简单，投资少，运行管理费用低， 一般情况下，应考虑节约电能和有色金属的消耗量。供配电系统变电所常用的主接线基本形式有线路-变压器组接线、单母线接线和桥 式接线3种类型。(1) 线路-变压器组接线 当只有一路电源供电和一台变压器的时可采用，有接线简单， 所用电气设备少，配电装置简单，节约投资等优点，但当该单元中任一设备发生故障或检修时，变电所全部停电，可靠性不高，所以线路

4、-变压器组接线方式只适用于小容 量三级负荷、小型企业和非生产性用户。(2) 单母线接线 母线又称汇流排，用于汇集和分配电能。单母线接线又可分为单母线 不分段和单母线分段两种。单母线不分段接线：当只有一路电源进线时，常用这种接 线，每路进线和出线装设一只隔离开关和断路器。当电源线路、母线或母线隔离开关 发生故障或检修时，全部用户供电中断。所以这种接线方式适用于对供电连续性要求 不高的三级负荷用户，或者有备用电源的二级负荷用户。单母线分段接线：当有双电源供电时，常采用单母线分段接线。可采用隔离开关或短 路器分段，隔离开关因操作不便，目前以已经不采用。单母线分段接线可以单独运行， 也可以并列同时运行

5、。(3) 桥式接线所谓桥式接线是指在两路电源进线之间跨接一个断路器，犹如一座桥。 断路器跨接在进线断路器的内侧，靠近变压器，称为内桥式接线。若断路器跨接在进 线断路器的外侧，靠近电源侧，称为外桥式接线。其适用范围为有两路电源供电及两 台变压器的情况。综合考虑以上因素，经过认真分析讨论，提出以下两种主接线图的设计方案，具 体如下。本变电站有两路电源同时供电，所以应该采用双回路电源进线，方案1采用低压单母线分段接线。1号方案是通过从两个电源进线，设两台10kV变压器。两台 10kV变压器，为两段低压母线提供0.4kV供电。在0.4kV低压母线上做母线联络。1 号方案的优点是经济，整个系统使用安全，

6、各变电所相对独立，系统简单，有一定可 靠性，能满足可靠性要求。缺点是10k V母线无联络，自闭母线和贯通母线可靠性低。 由于本变电所有两路电源同时供电，所以应该采用双回路电源进线。方案2一、二次侧均采用母线分段主接线，由于进线开关和母线分段开关均采用了断路器控制，操作 十分灵活，供电可靠性较高，适用于一、二级负荷供电。2号方案也是通过从两个电源进线，设两台10kV变压器。两台10kV变压器，为两段低压母线提供 0.4kV供电，并 且2号变电所的左右0.4kV低压母线上做母线联络，为低压设备提供可靠供电。除此 之外，2号方案在10kV的主母线上做母线联络，不仅提高了 2号变电所的供电可靠性， 而

7、且提高了自闭母线和贯通母线的供电可靠性。2号方案的优点是整个系统安全性较高， 并且可靠性能进一步提高，尤其提高自闭母线的供电可靠性意义重大，此方案可大大 提高其安全稳定运行。缺点是系统相对复杂和接线复杂使经济上的投入有了一定的增 加。对以上提出的两种方案进行比较讨论。在安全性方面，两套方案不相上下，都能 保证系统运行的安全。在可靠性方面，2号方案要略优于1号方案。因为2号方案在1 号方案的基础上增加了一次侧母线联络，可靠性得到提高。在使用灵活性方面，2号方案要优于1号方案。因为2号方案的电源转换和故障切换均可以在高压部分的一号变 电站处的母线连接中实现，也可以在低压部分实现，这样的使用灵活，方

8、便。在经济 性方面，1号方案有优势。1号方案在保证了可靠性的同时在10kV处比2号方案少了 一个母线连接的高压柜，节省了部分资金。其它方面双电源进线独立变电所的主接线采用一、二次侧单母线分段接线。这种接线 适用于有一、二级负荷的企业，变电所有两台或两台以上变压器。双回路电源进线高 压侧采用单母线分段后，供电可靠较高，操作灵活方便。综合以上五个方面的考虑， 结合实际设计中的各方面的需求，最终选择使用 2号方案的设计，作为该企业供电系 统的主接线图。变电所二次回路是保障一次回路正确、安全、可靠运行的系统。供配电系统的二 次回路包括用来控制、指示、监视和保护一次电路运行的回路，以及操作电源回路等。

9、二次回路按功能可分为断路器控制回路、信号回路、保护回路、监测回路和自动化回 路、操作电源回路等。操作电源向断路器控制回路、继电保护装置、信号回路、监测 系统等二次回路提供所需的电源。电压互感器、电流互感器还向监测、电能计量回路 提供电流和电压参数。二次回路的操作电源主要有直流操作电源和交流操作电源两类， 直流操作电源有蓄电池和硅整流直流电源两种。交流操作电源有电压互感器、电流互 感器。经比较：硅整流操作电源价格便宜，维护工作量小，体积小。所以此系统采用 硅整流直流操作电源。电磁操动机构的断路器工作原理：（1）断路器的手动控制手动合闸设断路器处于跳闸状态，此时控制开关 SA处于“跳闸后”（TD）

10、位置，其触电接 通，QF闭合，绿灯亮。因电阻1R存在，流过合闸接触器线圈KM的电流很小，不足以 使其动作。将控制开关SA顺时针旋转90度，至“预备合闸”位置（PC，将信号灯接于闪光 小母线（+） WF上，绿灯HG闪光，表明控制开关的位置与“合闸后”位置相同，但断 路器仍处于跳闸后状态，这是利用不对应原理接线，同时提醒运行人员核对操作对象 是否有误，如无误后，再将SA置于“合闸”位置（C）（继续顺时针旋转45度）。SA接 通，使合闸接触器KM接通于+W（和-WC之间，KM动作，其触点KM1和 KM2闭合，合闸 线圈通电，断路器合闸。断路器合闸后， QF1断开使绿灯熄灭，QF2闭合，由于SA接 通

11、，红灯亮。当松开SA后，在弹簧作用下，SA自动回到合闸后位置，红灯发出平光， 表明断路器手动合闸。同时表明跳闸回路完好及控制回路的熔断器完好。在此通路中， 因电阻存在，流过跳闸线圈的电流很小，不足以使其动作。手动跳闸将控制开关SA逆时针旋转90度置于“预备跳闸”位置（PT）,红灯发出闪光，表 明SA的位置与跳闸后的位置相同，但断路器仍处于合闸状态。将SA继续旋转45度而置于“跳闸”位置（T），使跳闸线圈接通，此回路中的跳闸线圈通电跳闸，QF1合上， QF2断开，红灯熄灭。当松开SA后, SA自动回到“跳闸后”位置，绿灯发出平光，表 明断路器手动跳闸，合闸回路完好。断路器的自动控制断路器的自动控

12、制通过自动装置的继电器触点的闭合分别实现合、跳闸的自动控 制。自动控制完成后，信号灯 HR或HG将出现闪光，表示断路器自动合闸或跳闸，又 表示跳闸回路或合闸回路完好，运行人员需将 SA旋转到相应的位置上，相应的信号灯 发平光。当断路器因故障跳闸时，保护出口继电器触点闭合，SA的触点被短接，跳闸线圈通电，断路器跳闸，HG发出闪光，表明断路器因故障跳闸。信号继电器电流型线圈通 电后将发出信号。同时由于 QF3闭合而SA只置“合闸后”（CD位置，事故音响小母 线WAS与言号回路中负电源接通（成为负电源），则起动事故音响装置，发出事故音响 信号。如电笛或蜂鸣器发出声响。断路器的防跳若没有防跳继电器，在

13、合闸后，如果控制开关 SA的触点或自动装置触点被卡死， 而此时又遇到一次系统永久性故障，继电保护使断路器跳闸，QF1闭合，合闸回路又被接通，则出现多次“跳闸一合闸”现象，这种现象称为跳跃。如果断路器发生多次跳 跃现象，会使其毁坏，造成事故扩大。所以在控制回路中增设了防跳继电器。自动重合闸装置简介：自动重合闸装置主要用于架空线路，本系统中，到变电所 的线路采用架空线路，所以用自动重合闸来保护线路的瞬时故障。电气一次自动重合闸装置（1）故障跳闸后的自动重合闸过程线路正常运行时， SA1和SA2是在合上的位置, 途中出1 3, 2123接通之外，其余接点均是不接通的， ARD投入工作，QF（1 2）

14、是 断开的。重合闸继电器KAR中电容器C经4R充电，其通电回路是+W&SA34FHC- WC同时指示灯HL亮，表示母线电压正常，电容器已在充电状态。当线路发生故障时，由继电保护（速断和过电流）动作，是跳闸回路通电跳闸，防 跳继电器KTL电流线圈起动，KTL（12）闭合，但因SA1 58不通，KTL的电压线圈不 能自保持，跳闸后，KTL电流电压线圈断电。由于QF（12）闭合，KAR中的KT通电动作，KT（1 2）打开，使5R串入KT回路， 以限制KT线圈中的电流，仍使KT保持动作状态，KT(3 4)经延时后闭合，电容器C 对KM线圈放电，使KM动作，KM( 12)打开后HL熄灭，表示KAR动作。

15、KM(34), KM(56), KM(78)闭合，合闸接触器 KM1 经 +W&SA3KM(3-4),KM(5 6) KM电 流线圈f KSXBKTL(3 4) QF(3 4)接通正电源，使断路器重新合闸。同时后加 速继电器KM2也因KM(7 8)闭合而起动，KM2辅助触点闭合。若故障为瞬时性的，此时故障应已消失，继电器保护不会在动作，则重合闸合闸成功。QF(12)断开,KAF内继电器均返回，但后加速继电器 KM2触点延时打开，若故障为永久性的，则继电 保护动作，KT1长开闭合，经KM2的延时打开触点，接通跳闸回路跳闸，QF(12)闭合，KT重新动作。由于电容器还来不及重组点，KM不能动作，即

16、使时间很长，因电容 器C与KM线圈已经并连，电容C将不会充电至电源电压值。所以，自动重合闸只重合 一次。(2) 手动跳闸时，重合闸不应重合因为人为操作断路器跳闸是运行的需要，无需重合闸，利用SA1的21 23和2 4来实现。操作控制开关跳闸时，SA1的2123均不通，跳闸后仍保持断开状态，从而可靠切断了重合闸的正电源，重合闸不可能动作。此外，在操作控制开关跳闸时， 在“预备跳”和“跳闸后” 24接通，使电容器与6R并联，C充电不到电源电压而不 能重合闸。(3) 防跳功能当ARD重合于永久性故障时，断路器将再一次跳闸，若 KAF中 KM(34)， KM(56)触点黏住时，KTL的电流线圈因跳闸而

17、被起动，KTL (12)闭合并能自锁， KTL电压线圈通电保持，KTL (34)断开，切除合闸回路，防止跳跃现象。继电保护装置的基本要求有四点：即选择性、灵敏性、速动性和可靠性1. 选择性 当供电系统中发生故障时，继电保护装置应能有选择性地将故障部分切 除。也就是它应该首先断开距离故障点最近的断路器，以保证系统中其它非故障部分 能继续正常运行。2. 灵敏性 灵敏性是指继电保护在起保护范围内，在发生故障或不正常运行状态的 反应能力。在继电保护的范围内，不论系统的运行方式，短路的性质和短路的位置如 何，保护都应正确动作。3. 速动性 速动性是指保护装置应能尽快地切除短路故障。缩短切除故障的时间，

18、就可以减轻短路电流对电气设备的损坏程度，加快系统电压的恢复，从而为电气设备 的自启动创造了有利条件，同时还提高了发电机并列运行的稳定性。4. 可靠性 保护装置应能正确的动作，并随时处于准备状态。如不能满足可靠性的要 求，保护装置反而成为了扩大事故或直接造成故障的根源。为确保保护装置动作的可 靠性，则要求保护装置的设计原理、整定计算、安装调试要正确无误；同时要求组成 保护装置的各元件的质量要可靠、运行维护要得当、系统应尽可能的简化有效，以提 高保护的可靠性。汉译英From anu mberof en terprisesareofte n available nearthe power suppl
