초록

산업사회의 발달과 더불어 신뢰성 높은 양질의 전기에너지와 운전 및 보수의 간편화, 계통 운용의 신뢰성, 안전성 확보가 요구되고 있다. 따라서 본 논문은 각종 전력설비에서 $SF_6$을 대체할 수 있는 친환경절연제로 연구되고 있는 $N_2-O_2$ 혼합가스($N_2:O_2=100$ : 0, 79 : 21, 60 : 40, 40 : 60) 절연파괴특성을 구명(究明)하여 이를 $SF_6$가스의 특성과 비교하였다. 이상의 연구 결과, 제조공기와 Dry-Air 절연특성을 구명함으로서 각종 전력응용 설비의 절연설계에 $SF_6$ 대신 친환경적인 모의공기를 사용 가능함을 본 연구에서 구명(究明)하였다. 제조공기를 이용한 친환경적인 절연재 사용으로 지구의 온난화현상 감소에 크게 기여할 것으로 기대된다.

With the improvement of industrial society, the high quality electrical energy, simplification of operation and maintenance, ensuring reliability and safety are being required. This paper compares breakdown characteristics in $SF_6$ gas with $N_2/O_2$ Mixture gas($N_2:O_2=100$ : 0, 79 : 21, 60 : 40, 40 : 60) as using widely in High Voltage insulation equipment with the characteristics in different media which are focused on environmentally friendly gases. As an append result of research the results are fundamental data for electric insulation design of Distribution Power Facilities which will be studied and developed in the future. And we could make an environment friendly gas insulation material with mataining dielectric strength by $N_2/O_2$ Mixture gas which generates a lower lever of the global warming effect.
