断器。[Scope of Claim for Utility Model Registration] A hollow movable arcing contact in which a fixed arcing contact is fixed in an insulating gas, and a driving rod is provided so as to be movable along the axis of the fixed arcing contact, and the fixed arcing contact can be freely inserted and removed. is formed at the tip of the drive rod, a puffer chamber surrounding the drive rod is provided outside near the tip of the drive rod, a flow guide is provided to cover the outer peripheral surface of the movable arcing contact, and an insertion hole is provided through which the fixed arcing contact is inserted. By providing the formed insulating nozzle so as to surround the flow guide, a discharge path extending from the puffer chamber to the vicinity of the insertion hole is formed between the flow guide and the insulating nozzle, and the insulating gas can be sucked into and discharged from the puffer chamber. In a puffer-type gas circuit breaker equipped with a suction/exhaust means, the tip of the flow guide is made of an insulating material that thermally decomposes to generate insulating gas and has heat resistance, so that the heat of the arc in the insulating material is directly absorbed. A puffer-type gas circuit breaker characterized in that the surface of the receiving part is covered with a heat-resistant metal material, and a hole or the like is formed in the metal material so that a part of the insulating member is exposed.
