Abstract
This paper introduces one GIS breaker short-circuit accident in some 220 kV substation.By comprehensively analy-zing fault recording,gas components,breaker disintegration and factory original data after the short-circuit fault,the main reason for the accident was considered to be defect of breaker interelectrode insulating cylinder caused by breakdown and discharge in factory lightning impulse test.Meanwhile,by review on the accident,correctness of accident reason analysis was verified from another angle and relevant suggestions were proposed for providing references on similar GIS fault handling a-nalysis.关键词
