1、摘要摘要本课题实现了某机械修造厂全厂总降压变电所的设计。首先确定总体放案，并通过全厂负荷情况确定主变压器及容量，并对功率补偿进行计算，确定合适的电容器，再确定变压器的接线方式。第三章对短路电流进行计算，以确定电器设备，然后进行校验，用以确定高压开关柜的型号，高压侧采用JYN1-35型，低压侧选用JYN2-10型，且均能满足要求，性能较为优良。在第五章中，对主变压器，线路进行气体、过电流、过负荷、电流速段保护、差动保护，并对保护进行了整定计算，做出保护设计图。同时，在考虑到地形、环境、经济、节约土地及方案的要求，确定了总降压变电站的平面布置图，最后对接地防雷进行了设计。设计还对功率补偿
2、方式进行了专题设计，采用无功功率补偿方式，是目前较为先进的补偿方式，用来降低由于被补偿电容的不合理造成的功率因数不稳定和电网的波动。关键词负荷计算，功率补偿，短路电流计算，电器选择校验，设备保护，接地防雷51摘要AbstractThistopichasrealizedsomemechanicalrepairshopentirefactoryalwaysvoltagedroppingresistortransformersubstationdesign.Firstdeterminedtheoverallputsthedocument,andthroughtheentirefactory
