Abstract (en)
[origin: EP4277057A1] Provided is a gas insulated switchgear that enables adjustment of the interruption speed while stabilizing the position where a fixed electrode is separated from a movable electrode. The gas insulated switchgear includes: a movable electrode (8) having a movable electrode rod (6) and a movable-side shaft rod (7); a fixed electrode (14) provided coaxially with the movable electrode; a driving portion which linearly drives the movable electrode; and an opening mechanism which separates the fixed electrode from the movable electrode. The movable electrode has a taper portion (7a) and a protrusion (6a) at a part to contact with the fixed electrode. The fixed electrode includes a latch portion (24) composed of a claw (20) having an engagement portion (20a) to be engaged with the protrusion and a slope portion (20b) to contact with the taper portion, and a contact-pressure spring (22) applying a restoring force to the claw.
