自助式GIS设备超声波局部放电在线检测方式探讨

摘要

By comparing ultrasonic-based on-line partial-discharge detection method and the ultra-high fre-quency on-line partial discharge monitoring system for GIS (gas insulated switchgear) equipment, the paper analyzes their shortcomings in test time and location. A self-service scheme of ultrasonic-based on-line partial discharge monitoring for GIS equipment is investigated, which owns better test effect and can make up the shortcomings of conventional test schemes.%通过对比超声波局放带电测试和特高频局放在线监测这2种现行常用的GIS(气体绝缘金属封闭开关设备)设备检测方式，分析两者在测试时间和测试位置上的不足，有针对性地研究一种新型的自助式GIS设备超声局放在线检测方式，获得了更好的测试效果，也弥补了常规检测方式的不足。
