LSF₆의 교류 및 직류전압에 대한 절연특성연구

In this paper the experiments of breakdown characteristics SF? liquid (LSF?) in model GIS(Gas Insulated Switchgear) were described. From the experiments results, The ability of LSF? insulation is higher than high-pressurized SF? gas. The breakdown characteristics of LSF? were produced by bubble formed evaporation of LSF? and bubble caused by high electric emission. It is considered in this paper that the results are fundamental data for electric insulation design of superconductor and cryogenic equipments machinery which will be studied and developed in the future.
