고체절연물에 따른 N₂:O₂ 혼합가스의 연면절연파괴특성

recently, The development of SF? gas with replaceable environmentally friendly gas is important from power facilities. insulation gas at institutional limitation complying with global warming, insulating oil weakness of volume and weight but when solid insulator was usefully used by insulation design because a solid better of dielectric strength than the gas, environmentally friendly and proper method are manufactured. in this paper describe the surface breakdown characteristics after teflon resin, Bakelite, Polyethylene of extensively to use solid insulator are installed between the electrodes in environmentally friendly N₂:O₂ mixture gas(10:0, 8:2, 6:4, 4:6) of experiment and measurement with surface breakdown voltage.
