Estimate of Flashover Position from E-field Calculation along Electrode Gap Distance

진공인터럽터 극간 랩거리 조정에 따른 각 부위의 전계값 계산을 통한 진공인터럽터 내부 절연파괴부위 예측

Because of power consumption increase, global warming, and limitation of installation, not only high reliability and interruption capability but also compact and light power apparatuses are needed. In this paper, various models that short and long gap distance were used to analyze E field of each model. Calculation value was estimated of flashover position. As a result, short and long gap distance that vacuum interrupter inner between move electrode and fix electrode not coincided flashover position of each model. short gap distance estimated flashover position at electrode edge. but long gap distance model confirmed $E_{max}$ value at center shield. in this paper was compared electric field value. and estimated of flashover position from electric field calculation.
