Prediction of Performance considering Ablated PTFE in High Voltage Self-blast Circuit Breaker
PTFE 용삭을 고려한 초고압 복합소호 차단기의 성능 예측
- Published : 2008.03.26
Abstract
Self-blast circuit breakers utilize the energy dissipated by the arc itself to create the required conditions for arc quenching during the current zero. During the arcing period, high pressure, temperature and radiation of the arc could burn in pure SF6 gas and PTFE nozzle. Ablated nozzle shape and
