Patent ID: 8878092

Claim:
A gas-insulated switchgear comprising: a fixed-side electrode including: a tubular fixed-side conducting contact, and a fixed-side shield that is disposed radially outward of, and surrounds, the fixed-side conducting contact, a movable-side electrode including a movable conductor driven by a driving unit to be connected to and separated from the fixed-side conducting contact, and a fixed-side arc shield in the form of a circular plate thinner than the fixed-side shield, and made of a material different from the material of the fixed-side shield, the fixed-side arc shield having an opening with a diameter larger than an outer diameter of the movable conductor, the opening being formed on a side of the fixed-side shield facing the movable-side electrode, the fixed-side arc shield causing an arc current to flow outward in a radial direction during contact parting of the fixed-side conducting contact and the movable conductor to generate magnetic flux on a surface thereof in a circumferential direction that produces a force acted on an arc in a direction of toward a central axis, the fixed-side arc shield containing an arc-resistant member for restricting the arc in the vicinity of the opening.
