The current research about SF 6 switchgear failures mainly focuses on various troubleshooting methods, while ignoring the impact of SF 6 gas decomposition products on equipment and the types of failures they reflect, and the application of SF 6 gas decomposition products to diagnose equipment failures still needs to be further explored and improved. Therefore, this paper focuses on the study of the decomposition process of SF 6 under partial discharge failure, and conducts theoretical analysis of the decomposition product composition of SF 6 under partial discharge failure, and detects SF 6 gas decomposition products by gas chromatography. Finally, it can be concluded that when the concentration of S 2 F 10 and S 2 OF 10 is about 5μL/L, the switchgear is likely to have a partial discharge failure. At this time, the maintenance personnel should deal with it in time to ensure that the switchgear can be put into use normally.
