摘要
本文论述了横磁触头真空灭弧室开断实际短路电流时的零前过程,开断电弧的一般特性,着重介绍了起始金属桥爆炸引燃的收缩型电弧的停滞现象,收缩型电弧的运动特性及其转变成扩散型电弧的条件等问题。
This paper describes arc motion and transition in vacuum interrupter between radial magnetic type contacts during actural short-circuit-current interruption.The arc immobility phenomemnon at beginning of interruption and then the arc motion and transition are discussed in detail.The suggestion on research task in pre-current-zero process of the arc interrupting is proposed.
