GIS在局部放电下的SF6气体分解产物实验研究
Experimental Study on Relationship of SF6 Decomposition Products and Partial Discharge in Gas Insulated Switchgear
摘要
Abstract
A 126 kV AC power frequency power supply,a GIS partial discharge testing platform,and a gas detection system are designed to simulate the fault state of discharge to ground.Subsequently,SF6 decomposed characteristic gas components induced by partial discharge are analyzed quantitatively,where the intensity of partial discharge is monitored with the pulse current method.The results show that:①The characteristic gas components from partial discharge-induced SF6 decomposition are SOF2,SO2,and S2OF10;②The volume fractions of SOF2 and SO2 exhibit positive correlation with duration and intensity of partial discharge; ③Adsorbent imposes effect on measurement of SF6 decomposition products.关键词
