The Characteriztics of Insulation and Discharge with a Variation of Temperature in $SF_6$
$SF_6$ 가스의 온도변화에 따른 절연특성
Abstract
In this paper the experiments of insulation characteristics by temperature change of SF6 gas and insulation characteristics about liquid SF6 in GIS(Gas Insulated Switchgear) were described. From this result, at low temperature, the breakdown voltage was increased with a drop of temperature and an increase of the inner pressure in GIS. The ability of insulation in liquid SF6 was higher than that of the highly pressurized SF6 gas.
