Decomposition of sf6 gas in an RF Plasma Environment

sf6 gas clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η Sulfr hexafluoride exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η sf6 gas was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W). The addition of oxygen to the reactor re-Get price

sf6 gas Decomposition in Gas-Insulated Equipment - IEEE Journals

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

Decomposition Characteristics of insulating gas and Partial Discharge

The decomposition characteristics of sf 6 under four types of negative DC partial discharge (DC-PD) are obtained. The relationship between the decomposition characteristics of sf6 gas and the PD types was further studied. Moreover, back propagation (BP) neural network algorithm [29–38] is used to recognize the PD types.Get price
