气体绝缘开关设备局部放电检测及定位实例分析

摘要

The on-site GIS partial discharge detection methods are introduced,and by comparing the various detection means,this study identifies with the partial discharge detection and positioning method using ultrasonic and UHF simultaneously. Field case analysis proves the proposed positioning method conducive to accurate fault location.%对现场使用的气体绝缘开关设备（GIS）局部放电检测手段进行了介绍,通过对各种局部放电检测手段的比较,确定了采用超声波和超高频同时进行局部放电的检测和定位的方法。对现场实例进行分析,确定文中采用的定位方法有助于对故障进行精确定位。
