要約(日本語): A three-dimensional electromagnetic thermal fluid simulation program is developed to simulate the movement of arc plasma with considering the metal vapor generated from the molten metal bridge along with electrode opening when an external magnetic field applied. In order to find out the change of arc voltage increment rate in different circumstances, and provide design feedback for improving the current direct current circuit breaker performance. It found out that the arc voltage increment rate became more rapidly when the electrode opening velocity is faster.
