項記載のガス開閉器。[Claims for Utility Model Registration] An annular arc extinguishing device consisting of a magnetic field generating device and an arc runner located on the lower surface of the magnetic field generating device in an insulating gas atmosphere, and an annular arc extinguishing device disposed near a hollow portion of the lower surface of the arc extinguishing device. A fixed contact and a movable contact having a butt contact structure are provided, and the arc generated by the opening of both the contacts is transferred from the fixed contact to the arc runner, and the arc is caused by the magnetic field of the magnetic field generator. In a gas switch configured to extinguish an arc by rotating at high speed on the lower end circumference of the hollow portion by electromagnetic force, a gas switch located above the movable contact on the central axis of the hollow portion below the arc runner. A gas switch equipped with an arc electrode with the same potential as the movable contact. A substantially annular shield electrode having the same potential as the arc electrode and cut out in the vicinity of the fixed contact is provided below the arc runner at a position substantially at the same height as the arc electrode so as to surround the outside of the arc electrode. Gas switch as described. A gas switch according to claim 1, wherein the surface of the shield electrode is coated with an insulating material.
