평등/불평등 전계하에서 제조공기(I-Air)와 SF₆에 대한 압력별 절연파괴특성

In this paper approves AC high voltage by experimental GIS(Gas Insulated Switchgear) chamber and AC 300[㎸] power source to study breakdown characteristics by pressure(P) change and change of electrode distance(d) at AC high voltage of Imitation Air(I-Air, N₂ : O₂ = 79[%] : 21[%]) to alternate SF? and achieved research. Gave P change of I-Air to study I-Air's breakdown characteristics using uniform(Sphere-Sphere electrode) and non-uniform fields(Needle-Plane electrode) and studied relations breakdown voltage (V B ) by each P different d.
