摘要
在简要介绍我国800kV高压套管首起绝缘故障情况的基础上,重点分析了故障原因,指出了高压套管绝缘薄弱部位,并提出了相应的措施,为后续750kV工程电气主设备高压套管的生产、运输、安装和运行维护提供了指导。
Following a brief description of the first insulation accident on the China-made 800 kV high voltage(HV) Bush,this paper focuses on exploring the origins of the default,and then reveals the weak part of the bush,and based upon the analysis,it comes up with the proper measures in preventing the similar accidents.This paper serves to offer useful guidance for manufacturing,transportation,erection and operation and maintenance of the HV bushes for main equipment in the coming 750 kV power transmission projects...
