50hz sf6 Components Detection for gis

Oct 01, 2020 · Sulfur hexafluoride (SF 6) has been widely applied in GIS as an effective insulating medium due to its excellent chemical stability and high dielectric strength . However, partial discharge caused by internal impurity or inevitable sharp edge can decompose SF 6 into several gas components such as H 2 S, SO 2, SO 2 F 2, SOF 2 and HF, which will further accelerate insulation deterioration and equipment aging [3], [4], [5] .
