查询词典 striking of arc

Many researchers have investigated the influence of AMF on vacuum arc. And most of them point out that uniformly distributed AMF is preferable. However, at higher current even under very uniform AMF, vacuum arc still tends to constrict, which will result in the failure of break. Further more, very strong uniform AMF has some disadvantages also.
