弧触头 meaning in Chinese

arc-rupturing contact
arcing contact

Switches play transmitting and cutting electrical current role during the working electrical net as a hinge , the important role will be brought into effect by the key part in switches - arc contact . if the contacts have invalidated and could not accomplished the important role during the working electrical net , switches would detonate , which result in the paralysis of whole net linked by the switches , the higher the transmitting voltage of net is , the bigger the affected area is , therefore , in order to decrease or avoid the arc eroding and invalidation during the net working , it is necessary to study the arc eroding and invalidation mechanism of contacts , sequentially make the whole net stable
可以说是电网中枢纽，而实施断路器重要作用的核心部件就是弧触头，如果在动态使用中由于触头的失效而不能有效开断的话，断路器就会整机爆炸，后果就是它所连接的整个电网处于瘫痪状态，电网的输变电电压越高，波及的面积越大，所以有必要对触头的动态烧损和失效进行详尽的分析，减少或避免实际使用过程中的烧损和失效，从而稳定整个电网。
