arc extinction
基本例句
灭弧
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.在电弧向灭弧栅片运动的过程中，聚合体材料受到电弧的烧蚀，灭弧室内充满空气和聚合体蒸气的混合气体。
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.它采用多个栅片的灭弧室，利用近极压降将进入到灭弧室中的电弧电压提升到一个较高的值，从而在开断电路的同时还起到对短路电流的限制。 |
