Claims

[Scope of Claim for Utility Model Registration] Forming a fitting part on the fixed side base into which the movable contact is fitted and removed, providing a fixed main contact on the inner peripheral surface of the fitting part, and providing a fixed arcing contact at the axial center position of the fitting part, A puffer cylinder facing the stationary side base is fixedly provided, a movable main contact is provided in the puffer cylinder so as to be able to move back and forth, and a piston is interlocked with the drive means and is slidably provided in the puffer cylinder to form a puffer chamber. A first movable arcing contact is formed at the distal end of the movable main contact, and a flow path formed from the distal end to the proximal end of the movable main contact is connected to the puffer chamber. A second movable arcing contact that does not block the flow path and is movable is accommodated in the channel, and a biasing means for biasing the second movable arcing contact toward the first movable arcing contact is provided. A gas disconnector characterized in that a stopper is formed to prevent an arcing contact from coming off from inside a flow path.
