Abstract

Abstract—In order to analyze the gas decomposition products under partial discharge by quality and by quantity, designed a 126kV AC industrial frequency power supply, a GIS partial discharge testing platform and a gas detection system, simulated the fault model of ground discharge, used pulse current method on discharge intensity monitor, concluded the characteristic of the concentrations of decomposition as well as its change in concentrations over time. The experimental results indicate that: SF6 gas decomposed into SOF2, SO2, S2OF10; SOF2, SO2 under partial discharge, this procedure has positive correlation with PD duration and partial discharge severity, adsorbent also has effects to the decomposition products.
