摘要电能是现代工业生产的主要能源和动力.随着现代文明的发展与进步，社会生产和生活对电能供应的质量和管理提出了越来越高的要求。工厂供电系统的核心部分是变电所。因此，设计和建造一个安全、经济的变电所，是极为重要的。此工厂供电设计包括：负荷的计算及无功功率的补偿；变电所主变压器台数和容量、型式的确定；变电所主接线方案的选择；进出线的选择；短路计算和开关设备的选择；二次回路方案的确定及继电器保护的选择和整定；防雷保护与接地装置的设计；车间配电线路布线方案的确定；线路导线及其配电设备和保护设备的选择；以及电气照明的设计，还有电路图的绘制。关键词：电能变电所变压器继电器接地装置ABSTRACTElectricenergyisthemainenergyanddynamismofmodernindustryproduction．Withdevelopmentandprogressofmoderncivilization,socialproductionandisitputforwardhighrequestmoreandmoretoqualityandmanagementthatelectricenergysupplytolive．Thesystemnucleusoffactorysuppliespoweristransformer．Itisveryimportanttodesignandbuildonesafeeconomicalsubstation．Thisfactorysuppliespoweranddesignsincluding:Calculationofloadandcompensationoftheinactivepower;Transformersubstationmainvoltagetransformerplatformcountandcapacity,surenessofpattern;Mainlywirethechoiceoftheschemeinthetransformersubstation;Passinandoutthechoiceofthethread;Choiceofshortingoutandcalculatingandswitchgear;Tworeturncircuitsurenessandchoicethatrelayprotectofschemeexactlymake;Defendthethunderandprotectthedesignwiththeearthdevice;Theworkshopdistributionlineconnectsupthesurenessofthescheme;Circuitwireanddistributionequipmentandprotectingthechoiceoftheequipment;Andtheelectricdesignthatlighted,thereisdrawingofcircuitdiagram.Keyword:ElectricenergySubstationTransformerTnterruptorThedesignwiththeearthdevice目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc105561360"前言1HYPERLINK\l"_Toc105561361"1原始资料及设计任务2HYPERLINK\l"_Toc105561362"2HYPERLINK\l"_Toc105561364"2变电所所址的选择4HYPERLINK\l"_Toc105561365"4HYPERLINK\l"_Toc105561366"4HYPERLINK\l"_Toc105561367"3负荷统计及无功补偿计算5HYPERLINK\l"_Toc105561368"5HYPERLINK\l"_Toc105561369"6HYPERLINK\l"_Toc105561370"10HYPERLINK\l"_Toc105561371"4变电所主变压器台数和容量的确定11HYPERLINK\l"_Toc105561372"11HYPERLINK\l"_Toc105561375"4.2变电所变压器的台数和容量的选择12HYPERLINK\l"_Toc105561376"5变电所主接线的选择14HYPERLINK\l"_Toc105561377"14HYPERLINK\l"_Toc105561379"5.2变电所的主结线方式16HYPERLINK\l"_Toc105561382
