sf 6 Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of sf 6 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, gaz sf6 decomposes to a wide variety of chemically active products which possess completely different properties from gaz sf6.Get price

Insights on decomposition process of c-C4F8 and c-C4F8/N2

It was found that the decomposition of c-C 4 F 8 /N 2 mainly produces CF 2, F, CF 3, CF, C, CF 4 and C 2 F 4. c-C 4 F 8 can decompose to C 2 F 4 by absorbing 43.28 kcal/mol, which is the main decomposition path and this process easily occurs under high temperature. There is a dynamic equilibrium process among the various produced radicalsGet price

Optical technology for detecting the decomposition products

PD can cause decomposition of SF 6 gas, resulting in the production of various low-fluorine sulfides, such as SF 4, SF 3, SF 2, and S 2 F 10. 1 – 3 Because of the presence of trace impurities, such as H 2 O and O 2, in the equipment, these low-fluorine sulfides generate many more stable decomposition products, such as SOF 2, SO 2 F 2, SO 2, and H 2 S.Get price
