The decomposition products of sulfur hexafluoride (Sulfr hexafluoride

Abstract. Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol.Get price

insulating gas Decomposition in Gas-Insulated Equipment - IEEE Journals

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

Decomposition Characteristics of gaz sf6 under Flashover

Derdouri et al. [ 12] designed a study on the SF 6 decomposition products when water vapor exists and found that SOF 2 and SO 2 F 2 generate stably in existence of water vapor. Later, it was found that SF 6 decomposition byproducts, including SOF 4, SOF 2, SO 2 F 2, SO 2, HF, would appear as long as water vapor and oxygen existed [ 13 ].Get price
