摘要：

The epoxy spacers in SF6 Gas Insulated Switchgear (GIS) are vulnerable to discharge. Once the surface of the epoxy spacers is deteriorated under discharge, insulation break down may occur subsequently. From a number of experiments carried out on 110 kV GIS, a new gas CS2 was detected when creeping discharges occur on the epoxy spacer surface. In order to verify the correlation between CS2 and the degradation of epoxy spacers, the quantum chemistry analysis was used to investigate the mechanism of CS2 development. Based on the results, the relation between CS2 and spacer insulation degradation was determined.
