摘要

分析了一起363kVGIS充电时闪络故障的原因

提出了GIS交接试验中做交流耐压试验的同时应进行局部放电的测量

并在条件许可的情况下进行操作冲击电压试验

以避免如绝缘子伤痕和裂痕、自由微粒、悬浮电位和异物遗留在GIS内部等原因而造成GIS故障。

Abstract

The paper gives the analysis of flashover fault of 363 kV gas insulated switchgear

and put forward that partial discharge should be measured during alternating current withstand voltage test in GIS handover tests.If conditions permit

switching impulse withstand voltage test should be carried out

which can detect GIS defects caused by insulator scar

free particle

suspension electric potential

and remain substance in GIS etc.effectively.
