摘要： A switchgear includes a fixed contactor provided in a tank filled with insulating gas, and a movable contactor provided in the tank, the movable contactor being connected to and disconnected from the fixed contactor so as to move forward and backward. The switchgear includes an arc extinction member including a surrounding portion which is slidably connected to the outer circumferential surface of the movable contactor halfway in a movement range from a close contact state to an open contact state and is formed so as to surround an arc space portion in a sealed manner, the surrounding portion being formed with a through hole through which the arc space communicates with the outside of the arc space.

摘要： A gas-insulated electric device, by which a cross-sectional area of a central conductor can be reduced. The gas-insulated electric device includes an insulation tube that ranges to portions facing to ground potential portions for a central conductor and to upper-lower portions along the grounding potential portions, and is coaxially arranged along the central conductor in a state where a gap intervenes between the central conductor and the insulation tube; a conductive layer that is formed on an inner surface of an insulation tube and is electrically connected to the central conductor; and a ground layer that is formed on an inner surface or an outer surface of the insulation tube and is grounded; in which heat generated from the central conductor is radiated by convecting the insulation gas through the gap between the central conductor and insulation tube.
