文档介绍：..摘要展望未来,我国能否在本世纪中叶基本实现现代化,相当大的程度上取决于能源。电力工业是国民经济的基础,是重要的支柱产业,它与国家的兴衰和人民的安康有着密切的关系,随着经济的发展和现代工业的建设的迅速崛起,供电系统的设计越来越全面、系统,工厂用电量迅速增长,对电能质量、技术经济状况、供电的可靠性指标也日益提高,因此对供电设计也有了更高、更完善的要求。变电站作为电能传输与控制的枢纽必须改变传统的设计和控制模式,才能适应现代电力系统、现代化工业生产和社会生活的发展趋势。本设计讨论的是220kV变电站电气部分设计(一次系统),首先根据原始资料进行分析,负荷计算选择主变压器,然后在此基础上进行主接线设计,再进行短路计算,导体和电气设备的选择,最后进行防雷接地设计。关键词:变电站;负荷计算;短路电流;设备选择;..ABSTRACTLookingahead,ourabilitytoachievethemiddleofthiscentury,modernization,,theriseandfallwiththeStateandthepeoplecloselyrelatedtothewell-being,alongwitheconomicdevelopmentandtherapiddevelopmentofmodernindustryrise,prehensive,systematic,rapidgrowthofplantconsumptionforpowerquality,onditions,reliabilityofelectricitysupplyareincreasing,andthereforealsohavehigherpowersupplydesign,,toadapttothemodernpowersystem,(asystem),Firstofall,analyzetheoriginaldataandchoosethemaintransformer,basedonit,designthemainwiringandShortCircuitCalculation,atlastchooseequipment,:substation;short-circuitcurrent;equipmentselection;distributionequipment..目录摘要...............................................................................................................................IABSTRACT................................................................................................................II1引言............................................................................................................................12电气主接线的设计..............................................................................................................................................................................................
