徴とする接地タンク式パツフア形ガス遮断器。 A fixed contact and a movable contact are provided in a metal container filled with arc-extinguishing gas, and when the movable contact shuts off, the gas in the cylinder is compressed, and this gas is transferred between the fixed contact and the In a circuit breaker that extinguishes an arc by blowing air onto the generated arc, a cylindrical insulating container is provided to house the movable and fixed contacts, and the insulating container is partitioned by providing an inner flange in the middle of the insulating container. In addition, a piston is disposed in one of the partitioned chambers in the insulating container, and is in sliding contact with the inner wall of the insulating container, and is also provided with a through hole that serves as a gas outlet, and this piston is inserted through the inner flange. The movable contact is fixed to one end of an operating rod that forms a part of an energizing path that is slidably arranged between two chambers in an insulating cylinder, and a movable contact is attached to the piston. When the insulating rod is operated by the operating mechanism and the operating rod is operated to shut off, the gas is compressed between the inner flange and the gas is sprayed onto the arcing contact of the fixed contact. A grounded tank type puffer type, characterized in that a shield for electric field mitigation is attached to the insulating rod connection part of the operating rod, and the other chamber side of the insulating container is fixed to a lid plate that covers one end of the metal container. Gas circuit breaker.
