摘要

气体绝缘金属封闭开关(gas insulated switchgear

GIS)设备内部自由颗粒缺陷对GIS设备安全稳定运行构成较大危害

通过对GIS自由颗粒特性进行分析

提出采用超声波局部放电检测技术检测GIS中自由颗粒缺陷的方法。应用结果表明:超声波局部放电检测能有效检测出GIS设备内部自由颗粒缺陷

提前发现潜伏性缺陷

保障设备安全运行。

Abstract

The free particle defection inside gas insulated switchgear(GIS)harm safe and steadyoperation of GIS equipment. By analyzing the characteristic of free particle in GIS

puts forward themethod to detect free particle defection in GIS using ultrasonic partial discharge detection technology.The application result shows that ultrasonic partial discharge detection technology can effectively findout free particle potential defection inside GIS equipment

ensure the safe operation of GIS equipment.
