Advantages of sf6 gas switchgear sensor

Dec 19, 2019SF6 gas has been used extensively since the mid 1950s to replace oil as an insulator in electric equipment, and more recently in gas insulated switchgear (GIS) and gas insulated lines (GIL). It is also used in medium voltage switchgear primarily outside the United States and extensively worldwide in low switching capacity gear.

  • Nanomaterials Based Gas Sensors for SF6 Decomposition

    Authored by Xiaoxing Zhang. The insulating medium used in gas-insulated switchgear is SF6 gas, which has been widely used in substations. Energy generated by discharge will cause the composition of SF6 and generate characteristic component gases. Diagnosing the insulation defect through analyzing the decomposed gases of SF6 by chemical gas sensors is the optimal method due to its advantages.
