  • A review on SF6 substitute gases and research status of

    Nov 01, 2018SF6 is a non-combustible gas with good insulating properties and quenching arc performance. By 1938, Cooper from American suggested it as an insulating medium. In the same year, V. Grosse from German has proposed SF 6 as arc media of the high-voltage circuit breaker. SF6 gas was supplied commercially in 1947.Cited by: 12

  • The SF6 Decomposition Mechanism: Background and

    Gas 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 phenomenon would greatly reduce the
