要約(日本語): GCB (Gas Circuit Breaker) should be downsizing in order to decrease the size and cost. However, the downsizing has a limit because of the pressure rising, the ablation gas and metal vapor. It is important for the radiation power and temperature distribution of arc to determine the appropriate wall radius, because the ablation gas is affected by the radiation power and heat transfer of arc. In this paper, the radiation power increment emitted from argon and metal vapor affected by the temperature and volume effect in wall-stabilized arc of water-cooled vortex type is elucidated with the theoretical simulation and experiment. As a result, the radiation power emitted from argon and metal vapor increased with increasing the temperature and volume effect which is defined by the current and wall radius, respectively.
