Claims

[Scope of Claim for Utility Model Registration] A fitting part is formed on the fixed side base, a fixed main contact is provided on the inner peripheral surface of the fitting part, and a rod-shaped fixed arcing contact having a large diameter part is attached to the bottom side of the fitting part. A biasing means is provided at a position eccentric to the axis of the fixed side base so as to be able to slide a certain amount along the axis, and biases the large diameter part toward the bottom of the insertion part, and the insertion part of the fixed side base and Opposing puffer cylinders are fixedly provided, and a movable main contact that makes sliding contact with the fixed main contact is provided in the puffer cylinder so as to be movable back and forth, and is interlocked and connected to a drive means, and is slidably provided in the puffer cylinder and is connected to the puffer chamber. A piston forming the movable main contact is coupled to the movable main contact, and a movable arcing contact is provided at the tip of the movable main contact, and a flow path formed by penetrating the movable arcing contact toward the base end of the movable main contact is communicated with the puffer chamber. A gas disconnector characterized in that a fixed arcing contact can be inserted into a flow path of a movable arcing contact so as to freely make sliding contact.
