一起750 kV隔离开关故障原因分析

A 750 kV Isolating Switch Fault Analysis

GIS设备主要是由导电材料及绝缘材料组成,绝缘材料在运行过程中受到电、热、化学、环境等因素的影响逐步裂化,造成设备故障,引起供电中断。本文就一起750 kV GIS设备隔离开关内部故障进行原因分析并提出相关建议。

GIS equipment is mainly composed of conductive materials and insulation materials,insulation materials in the process of operation by electrical,thermal,chemical,environmental factors such as the impact of gradual cracking,resulting in equipment failure,resulting in power supply interruption.This paper analyzes the causes of an internal fault of 750 kV GIS equipment disconnecting switch and puts forward relevant suggestions.
