要約(日本語): In DC circuit breaker , the application of magnetic flux density is used to extinguish the arc plasma. However, it is difficult to extinguish the arc because high temperature gas and metal vapor existing makes conductivity high in sealed arc quenching chamber. The pressure on the advanced side becomes high, because high temperature gas collide to the wall. As a result, the arc returns to the inter-electrode area because of this pressure distribution. In this paper, the pressure distribution of high temperature gas reflection from the walls in arc quenching chamber was analyzed.
