Sulfr hexafluoride Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of sf 6 as an insulating gas has led to many studies on insulating gas 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 Sulfr hexafluoride.Get price

The decomposition products of sulfur hexafluoride (sf6 gas

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

The gaz sf6 Decomposition Mechanism: Background and Significance

Jan 24, 2017 · Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (Sulfr hexafluoride) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of Sulfr hexafluoride to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition phenomenon would greatly reduce theGet price

Theoretical study of the decomposition mechanism of sf 6/Cu

Sep 10, 2018 · Among all the decomposition pathways, the favorable decomposition reactions of SF 6 + Cu mixtures are found: reaction R1 contributes more than reaction R2 in the decomposition of SF 6 + Cu mixtures due to its lower energy released; reaction R3 is dominant in the decomposition of SF 5 + Cu other than multi-step reactions; the chemical processes of SF 4 + Cu → IM x → TS y (where x stands for 9, 10 and 13, and y denotes 7, 8 and 9) may play the same role in SF 4 + Cu decomposition, but theGet price
