特徴とするパツフア式ガス遮断器。 A puffer has a pair of electrodes that are arranged opposite each other so that they can come and go, and extinguishes the arc generated when the pair of electrodes open by spraying high-pressure insulating gas formed in a puffer chamber through an insulating nozzle. In the type gas circuit breaker, the distance of the gas flow path from the outlet of the puffer chamber to the throat portion of the insulating nozzle is approximately 3.5 times the diameter of the throat portion of the insulating nozzle, and the blowing angle of the insulating gas is is set at approximately 30° with respect to the operating axis of the pair of electrodes.
