Switchgear

A switchgear comprising:

• a sealed tank with an insulating gas enclosed therein;
• a fixed contact disposed in the sealed tank;
• a movable contact coming into contact with or separating from the fixed contact;
• an operating mechanism allowing drive force for movement of the movable contact to be generated, the operating mechanism for operating the movable contact generating operating force through current reception;
• a power supply that drives the operating mechanism;
• a control device that controls a pattern and/or timing of a current to be applied from the power supply to the operating mechanism;
• and
• outside the sealed tank, an earthing-switch fixed electrode, an earthing-switch movable electrode that comes into contact with or separate from the earthing-switch fixed electrode, and an operating mechanism for operating the earthing-switch movable electrode, wherein
• the operating mechanism includes a mover including permanent magnets or magnetic materials arranged in a motion axis direction of the mover while N poles and S poles are alternately inverted, magnetic poles disposed to be opposed to the N poles and the S poles of the mover, and windings, and allows the mover to stop linearly at three or more positions.
