SF6 Decomposition process for extra high Voltages

SF6 Decomposition process for extra high Voltages

As a promising alternative for pure SF6, the mixture of SF6/N2 appears to be more economic and environment-friendly on the premise of maintaining similar dielectric properties with pure SF6. But less attention has been paid to the thermal properties of an SF6/N2 mixture, especially with insulation materials overheating happening simultaneously. In this paper, thermal decomposition

  • Chemical Decomposition of High Pressure SF6/N2 (5:95

    Abstract. Sulfur hexafluoride (SF 6) is the insulator gas used in most of equipments handling high and very high voltages.Owing to its high global warming potential, SF 6 has been classified during the Kyoto conference on climate change among the greenhouse gases. Its emission in the atmosphere must therefore be reduced 1.InCited by: 1

  • 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 decompositionCited by: 1

    2018-11-1SF 6 gas is widely used in electric power apparatus as an insulation and arc-quenching medium. However, the application of SF 6 gas faces two serious problems, including the heavy global warming effect and high toxicity of its decomposition products. So, scholars committed to finding environmental-friendly alternative to SF 6
