要約(日本語): The molded case circuit breakers (MCCBs) are applied in the low-voltage power distribution system to interrupt the fault current._x000D_ When a MCCB interrupts the fault current, the arc is generated and raises the internal pressure of the MCCB._x000D_ Therefore, the MCCB structure must withstand an increase in internal pressure._x000D_ To calculate the internal pressure, we have used 3D magneto-hydrodynamic(MHD)._x000D_ However, this method takes time. Therefore, we established one-dimensional numerical model that can analyze internal pressure in a short time._x000D_ In this paper, we report the internal pressure analysis during current interruption for MCCB structures.
