It is well known that the melting of electrodes (mainly anode melting) in vacuum arc can increase the metal vapor density around current zero and even lead to interruption failure. In order to clarify the anode activities and their influence on arc appearance and interruption capacity, series experiments of cup-shaped axial magnetic field copper electrodes were conducted. Obvious anode melting was detected, the liquid copper flowed on the contact plate of anode and formed a clockwise swirl flow. The appearance of anode melting is correlated to the transition of arc mode. The melting of anode was severer than cathode and was influenced by the distribution of cathode spots. The material lost of anode was mainly in form of liquid droplets sputtering out of gap or flow into the cup of electrode, the copper vapor evaporated into arc column only accounted for a few portions.
Keywords:Anode melting;axial magnetic field contacts;contact erosion;vacuum arcs
