This paper describes the causes of SF6 gas decomposition products, and proposes the use of SF6 gas decomposition products to diagnose the internal faults of GIS and other equipment through the correlation analysis of decomposition products. Practice shows that the use of detecting the components and content of SF6 gas decomposition products can judge the internal faults of GIS. It has a good guiding significance for the operation monitoring and fault diagnosis of GIS in power switching station.

In fact, in the process of SF6 gas production will be affected by the material of the production equipment, process conditions and other factors, in addition to the water generated in the synthesis process, in the gas filling process may also be mixed with a small amount of water. In order to prevent the possible harm of sulfur hexafluoride gas moisture, the state has strict regulations on the quality indicators of SF6 gas, requiring manufacturers to provide biological test non-toxic certificate
