1000 kV特高压GIS绝缘故障及实例分析

Insulation Fault and Example Analysis of 1 000 kV UHV GIS

结合一起特高压站1 000 kV设备绝缘故障缺陷,介绍了绝缘故障的定位、分析方法,通过保护动作信息、设备带电情况、SF6气体组分测试情况、设备结构可以准确定位故障区域并分析故障原因,可作为特高压GIS设备故障定位、判断、分析工作的参考。

In this paper, the fault location and analysis method of insulation fault is introduced combined with an insulation fault of 1 000 kV equipment in UHV station. The fault area is accurately located and the fault cause is analyzed by protecting action information,the equipment electrification,the test situation of the SF 6 gas component and the structure of the equipment. This kind of fault is very typical in UHV GIS equipment,and can be used as reference for fault location, judgment and analysis.
