要約(日本語): The magnetic driven arc doesn’t advance smoothly between the parallel electrodes with edges. The anode spot stagnates on the ignited point when the arc column and cathode spot move forward. According to the experimental pictures, when the high temperature gas exists near or contacts with the anode, a new anode spot appears and the electrical breakdown occurs. In the meantime, the original anode spot disappears. It is well-known as re-strike phenomenon. In this paper, a 3-dimensional electromagnetic thermal fluid simulation program is developed, in order to elucidate the re-strike phenomenon derived from distribution of the conductivity and concentration of Cu vapor. As a result, the re-strike phenomenon depend on the distribution of them.
