電弧電接觸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
可以說是電網中樞紐,而實施斷路器重要作用的核心部件就是弧觸頭,如果在動態使用中由於觸頭的失效而不能有效開斷的話,斷路器就會整機爆炸,後果就是它所連接的整個電網處于癱瘓狀態,電網的輸變電電壓越高,波及的面積越大,所以有必要對觸頭的動態燒損和失效進行詳盡的分析,減少或避免實際使用過程中的燒損和失效,從而穩定整個電網。Standard guide for arc erosion testing of electrical contact materials
