gaz sf6 Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of sf 6 as an insulating gas has led to many studies on sf 6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, sf 6 decomposes to a wide variety of chemically active products which possess completely different properties from sf6 gas.Get price

Decomposition Characteristics of sf6 gas under Flashover

In this paper, the flashover discharging experiment was carried out on epoxy resin surface in an Sulfr hexafluoride atmosphere under pin-plate electrodes, with the electrodes distance from 5 mm to 9 mm. The concentration of seven characteristic gases was detected, indicating that the concentration of SOF2 and CF4 was the two highest, followed by SO2, CO2, SO2F2, CS2, and H2S. Based on the changes in theGet price
