배전급 전력설비를 위한 N₂-O₂ 혼합가스의 절연성 평가

Breakdown Characteristics Assess of N₂/O₂ Mixture Gas for Distribution Power Facilities

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 focuses on breakdown characteristics of N₂/O₂ Mixture gases (N₂ : O₂ = 100:0, 79:21, 60:40, 40:60) which are considered as environmentally friendly gases used for High Voltage insulation equipment. The characteristics of N₂/O₂ gases are compared with the breakdown characteristics of SF6 gas. As following results, this study contributes to provide a 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 maintaining dielectric strength by N₂/O₂ Mixture gas which generates a lower lever of the global warming effect.
