SF6-N₂混合 가스에서 正.負極性 捧對平板 電極에 대한 충격파괴전압 및 코로나 特性 = Impulse Breakdown and Corona Characteristics of Positive & Negative Rod-Plane Gaps in ?? Mixtures

국문 초록 (Abstract)

SF6-N₂ 혼합가스에서 불평등 전계에 의한 충격파괴전압(50% FOV)과 코로나에 대해서 조사 연구하였다.
본 실험결과에 의하면 SF6 에 대한 SF6-N₂혼합가스의 경제적 대체이용은 SF6(50%)- N₂(50%)의 혼합으로 가능하다는 것을 절연파괴 실험과 코로나 발생에 대한 도형분석으로 알 수 있었다.

Sulphur-hexafluoride(SF6) has extensively been used as an insulating gas electric power equilpment in substation for it's high dielectric strength, but it is very exensive and it is very senible to the locally high electric field strength.
To resolve these problems, I studied 50%FOV and corona characteristics of SF6-N₂ -N₂Mixtures under positive and negative Impulse voltage using a rod-plane gap. 50%FOV of SF6(50%)-N₂(50%) Mixtures was about 85% of fure SF6and it was known that SF6-N₂ Mixtures can be used as an economic insulation gas for SF6.
