Analysis of surface flashover along shield gap inner vacuum interrupter

진공 인터럽터 내부 쉴드간 gap에 따른 연면방전 특성파악

this paper describes the electric field distribution analysis along a shield gap inner vacuum interrupter(VI). The equipotential line and electric field and field vector in a VI are analysed by a finite element method and experiment at shield gap. in result, The equipotential line and electric field distribution was affected to VI shield gap. The reason is as it gets distortion of equipotential line done. finally, this paper recognized whether or not affected, and proposed gap with the most suitable shield length and an external insulation.
