摘要： A gas-insulated bus is provided with: a current-carrying conductor disposed along the axial direction of a metallic container that is filled with an insulating gas; a shield fitting through which passes the current-carrying conductor and that has a depressed portion formed on a portion of a barrel-shaped outer surface; an insulating support that has a first end thereof fixed in the depressed portion of the shield fitting and has a second end thereof fixed to the metallic container, and that supports the current-carrying conductor via the shield fitting; an internal conductor that is implanted in the second end of the insulating support and that, along with the second end, is positioned in the depressed portion and fixed to the shield fitting; and a contact that is attached to the inner surface of the shield fitting, that is disposed in a space formed on the inside of the shield fitting, and that makes contact with the current-carrying conductor so as to maintain the shield fitting and the current-carrying conductor at the same electric potential, wherein the internal conductor has such a shape that the internal conductor and the shield fitting together form a substantially barrel-like profile.

摘要： A transformer (10) includes a leg iron core (14) including a plurality of magnetic sheets stacked in one direction (Z axis direction), and a coil (21) wound around the leg iron core (14). A slit (16) is formed in at least a magnetic sheet which faces an inner peripheral surface of the coil in a stacking direction of the plurality of magnetic sheets, of the plurality of magnetic sheets. Since eddy current is divided by the slit (16), eddy current density can be reduced. By reducing the eddy current density, loss density in an iron core (15) can be reduced. By reducing the loss density in the iron core (15), loss in the transformer (10) can be reduced.

摘要： A gas-insulated switchgear (91-97) includes a fixed-side electrode (10) and a movable-side electrode (20) facing each other in a container filled with an insulating gas. The fixed-side electrode (10) includes a tubular fixed-side conducting contact (11) and a fixed-side shield (12) for housing the fixed-side conducting contact (11). The movable-side electrode (20) includes a movable conductor (21) driven by a driving unit to be connected to and separated from the fixed-side conducting contact (11). The gas-insulated switchgear (91-97) includes a fixed-side arc shield (13) in the form of a circular plate. The fixed-side arc shield (13) is made of an arc-resistant member and has an opening (13x) of a diameter larger than the outer diameter of the movable conductor (21), the opening (13x) being formed on the side of the fixed-side shield (12) facing the movable-side electrode. The fixed-side arc shield (13) is formed into a thin plate so that the fixed-side arc shield (13) causes an arc current to flow outward in a radial direction during contact parting of the fixed-side conducting contact (11) and the movable conductor (21) to generate magnetic flux on a surface thereof in a circumferential direction that produces a force acted on an arc in the direction of a central axis, thereby restricting the arc in the vicinity of the opening (13x).
