On Gas Supervisory Detection for Sulphur Hexafluoride Gas-insulated Metal-enclosed Switchgear in Operation

Weijian Wang

Abstract

Sulphur hexafluoride(SF6) gas-insulated metal-enclosed switchgear(GIS) has found wider and wider applications in China's power system.As a result,it is especially important to establish effective detecting means for gas analysis in operation and conduct supervisory management of such power equipments.Based on the problems in the operation of the 110 kV GIS and corresponding treating experience of 220 kV Fenjin Substation under Shenzhen Power Supply Bureau,this paper offers some proposals about the gas supervisory detection for SF6 GIS,thus supplying reference to the safe operation and supervision of SF6 GIS.
