したことを特徴とするパツフア式ガス遮断器。 It is equipped with a fixed arc contact and a movable arc contact disposed opposite to the fixed arc contact so as to be able to move toward and away from the fixed arc contact, and an arc generated between the fixed and movable arc contacts when the fixed and movable arc contacts are separated. In a puffer type gas circuit breaker that extinguishes the arc by spraying compressed and pressurized insulating gas in a puffer chamber, the blowing of the insulating gas is provided inside the movable arc contact and on the outside of the movable arc contact and has a throat part. A fitting part is provided on the fixed arc contact side of the movable arc contact through a flow path formed between the movable arc contact and the insulating nozzle. 1. A puffer type gas circuit breaker, characterized in that the inner diameter on the side opposite to the fixed arc contact element with respect to the fitting part of the child is approximately the same diameter as or smaller than the minimum inner diameter of the fitting part.
