It is a very high advancement to the development from two - pressure arc - quenching chamber and single - pressure arc - quenching chamber to the self - energy arc - quenching chamber now for arc - quenching theory of sf6 cb make use of the arc blocking effect , namely arc - self - energy , to increase sf6 gas pressure in the arc - quenching chamber and get the efficient blasting effect to extinguish the arc when the arc current is zero Sf _ 6斷路器從雙壓式、單壓式發展到如今的自能式是斷路器滅弧原理的一個重大飛躍。自能式sf _ 6斷路器利用電弧阻塞效應即利用電弧本身的能量使滅弧室內sf _ 6氣體的壓力升高,在電弧過零時產生有效的氣吹而熄滅電弧。
