Abstract
Target gas monitoring of partial discharge (PD)is an important basis and means to achieve defect warning of gas insulated switchgear(GIS).To explore the relationship between the potential target gases of HF and H2S and PD in GIS,four typical PD patterns were set up on experiment platform,studying the variation of decomposition products HF and H2S under different kinds of discharge.On the basis,the effect of three typical molecular sieve adsorbents was also considered.Experiments results showed that HF and H2S were two important target gases of PD in GIS,HF to reflect strong PD,and H2S to characterize serious solid dielectrics discharge of epoxy resin such as basin-type insulator.Because of the chemical properties of the two gases and the strong adsorption of molecular sieve adsorbents,the target gases of HF and H2 S are difficult to long-term stabilize in GIS.Therefore,the research and application of HF and H2S on-line monitoring technology will be of great significance to accurately assess the insulation state of GIS by chemical diagnosis method.关键词
