摘要
中低压配电网络设备有主变高压侧备自投和主变低压侧备自投两种模式,其中高压侧备自投分为进线备自投和分段桥备自投.为防止误合闸于永久故障造成母线的二次振荡,须根据不同主接线方式闭锁相应备自投.分析了上海市市区供电公司配电网不同主接线的备自投方式及其闭锁原因并进行总结.最后列举了相应的闭锁方式.
Abstract
Two modes of spare power automatic switching which equip in the high and low voltage side of main transformers are used in the low voltage distribution network.The former one is divided into FBZT and LBZT.To prevent the secondary oscillation caused by closing switches on the permanent failure,the automatic switching should be looked according to the different main electrical wiring diagram.This paper analyzes the different modes of BZT used in corresponding wiring diagram of Shanghai urban power supply company distribution networks.The reason for the spare power automatic switching interlock is summarized.Finally,the technology of interlock is introduced in this pa
