When the arc is moving to the splitters, the polymer is vapourized and the mixture of air and polymer vapour is filled in the arc chamber. 在電弧向滅弧柵片運動(dòng)的過(guò)程中，聚合體材料受到電弧的燒蝕，滅弧室內充滿(mǎn)空氣和聚合體蒸氣的混合氣體。
With an arc quenching chamber having splitters, the breaker makes the arc voltage,which can limit the short circuit current, to a higher value through the near polar voltage drop. 它采用多個(gè)柵片的滅弧室，利用近極壓降將進(jìn)入到滅弧室中的電弧電壓提升到一個(gè)較高的值，從而在開(kāi)斷電路的同時(shí)還起到對短路電流的限制。
