摘要
气体绝缘金属封闭开关设备(GIS)相对于常规敞开式开关设备具有占地面积小、运行可靠性高、防污闪能力强等众多优点,近年来被大量应用于电力系统.GIS的绝缘水平是现场交接试验最重要的试验项目之一,试验现场一般通过进行串联谐振试验来考核 GIS的绝缘水平.基于此,文章详细介绍了试验现场 GIS进行串联谐振试验的方法及流程,并结合案例分析了串联谐振耐压试验对发现GIS内部异常情况所起的作用.
Abstract
Gas insulated switchgear(GIS)has many advantages over conventional open switchgear,such as small footprint,high operational reliability,and strong anti pollution flashover ability.In recent years,it has been widely used in power systems.The insulation level of GIS is one of the most important test items for on-site handover testing.Generally,the insulation level of GIS equipment is evaluated through series resonance testing on site.This article provides a detailed introduction to the method and process of conducting series resonance testing on GIS equipment on site,and analyzes the role of series resonance withstand voltage testing in discovering abnormal situations inside GIS through case studies.
