要約(日本語): The GCB (Gas Circuit Breaker) has a problem of the thermal re-ignition which occurs after the arc interruption. In this paper, the re-ignition voltage with changing the gas bluster shape using the electromagnetic thermal fluid simulation was elucidated. As a result, the arc interruption performance improved because the arc temperature decreased because of the dominant radial convection in the case of the appropriate gas bluster shape.
