220 kV GIS母线分段开关刀闸气室SF_6气体突发泄漏分析及处理

Analysis of SF_6 Gas Outburst in 220 kV GIS Bus Sectional Switch Switch Gas Chamber

GIS设备在电力系统中已普遍推广使用。当前,GIS设备已投入运行10多年,GIS气室SF6气体泄漏问题日益突出。因此,介绍2010年投运的500 kV变电站,在220 kV系统双母双分段母线接线方式下,对母线分段开关刀闸气室SF6气体突发泄漏的紧急处理、预案措施进行分析,并提出相关合理化的建议。

Equipment of GIS has been widely used in power systems.At present,the equipment has been put into operation for more than 10 years,the existing problem of SF6 gas leakage is becoming more and more prominent.This paper introduces a 500 kV transformer substation which is put into operation in 2010,It offer proposal on the emergency treatment and plan measures of SF6 gas leakage problem in gas chamber of busbarsegment switch isolator.which is based on dual bus dual subsection connec mode of 220 kV system.
