SF6 Decomposition Analysis for middle voltages

Correlation analysis between SF6 decomposedTo obtain and understand the decomposition characteristics and decomposition process of sf 6 gas under different negative DC voltages, a physical model of the needle‐plate defect is used to conduct decomposition experiments of sf6-gas gas. Experimental results show that, under different negative DC voltages, the partial discharge (PD) caused by the needle‐plate defect decomposes sf6 gas

  • The SF6 Decomposition Mechanism: Background and

    2017-1-24Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition

  • SF6 Decomposition in Gas-Insulated Equipment - IEEE

    Abstract: The increasing application of SF6 as an insulating gas has led to many studies on SF6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, SF6 decomposes to a wide variety of chemically active products which possess completely different properties from SF6.
