Abstract

Recently, the vacuum interrupters have been most widely used in medium voltage level. In the vacuum circuit breaker the most influential part is vacuum interrupter. By performing the precise electromagnetic analysis of the interrupter, we increase the capability of large current interruption. In this paper, diffuse arc and constricted arc are modeled to perform 3D electromagnetic analysis, and also flux distributions and electromagnetic force is calculated at the contacts' separation. It is expected these results will be used importantly in developing the new vacuum interrupters.
