Claims

[Claims for Utility Model Registration] 1. The contact part of the fixed electrode is formed in the main body case filled with arc-extinguishing gas so that the center protrudes, and the movable electrode part is connected to the arm fixed to the rotating shaft. The movable electrode part is attached rotatably in the center, and the contact part provided at the tip thereof faces the fixed electrode so as to be able to come into contact with and separate from it, and when the rotary shaft is turned in or out, the movable electrode part By rotating the movable electrode part around the attachment part of the movable electrode part, the contact part of the movable electrode part can slide into contact with the contact part of the fixed electrode, and the rotation shaft completes the closing operation. A biasing member is provided that biases the contact portion of the movable electrode portion in the pressure contact direction with respect to the fixed electrode when the contact portion of the movable electrode portion is pressed against the fixed electrode. and a ferromagnetic adsorption member fixed to the base end of the movable contact so as to surround the movable contact, and when current flows through the movable contact, the fixing plate and the adsorption member A gas switch characterized in that a magnetic circuit is formed to cause the adsorption member and the fixed plate to adsorb each other, thereby making it possible to press the contact part of the movable electrode part against the fixed electrode which is the contact part of the fixed chamber pole part. Electrode structure. 2. The movable electrode part is inserted into the arm in a direction orthogonal to the rotation axis, and has a bent part in the center that rotatably locks on the fixed electrode side side of the arm, and the biasing member is attached to the movable electrode part. A support rod that is wrapped around the support rod, one end of which is locked to the upper end of the arm, and the other end of which is locked to the upper part of the arm, is inserted through the upper part of the arm so as to be movable up and down, and the lower end is attached to the base end of the movable electrode part. An electrode structure for a gas switch according to claim 1 of the registered utility model. 3. A utility model registration claim characterized in that the contact part of the movable contact is bent in a step-like manner through the locking part so that the rotation shaft is located at the center of the contact part of the fixed electrode when the closing operation is completed. An electrode structure for a gas switch according to item 1 or 2. 4. The gas switch according to any one of claims 1 to 3 of the claims registered as a utility model, characterized in that a stirring plate for stirring arc-extinguishing gas is provided at the tip of the movable electrode part. Electrode structure.
