Abstract
PD(partial discharge) of UHV substation GIS is more serious than EHV substation,on-line UHF partial discharge monitor can detect inside partial discharge,however,there are still some problems such as poor reliability and high misinformation rate.This paper expounds the application status and configuration situations of partial discharge on-line monitoring technologies for UHV substation GIS,analyses the existing problems,and presents corresponding promotion measures.Combined the application situation of on-line monitoring in UHV Substation,it is proved that GIS partial discharge on-line system has foreseeability of some GIS internal failure.After taking the improvement measures,with mobile charged detection technology,the failure of GIS partial discharge can be traced and found effectively,and the major UHV equipment failure can be avoided.关键词
