To provide a switch unit that has a structure in which triple points do not occur, and the occurrence of cracks is suppressed even when heat stress is applied.SOLUTION: A switch unit includes a switch in which a fixed electrode and a movable electrode are disposed so as to be freely contactable with each other, an air insulation operation rod connected to the movable electrode, an electromagnetic actuator that drives an air insulation operation rod, an insulating case that covers the switch, a mechanical case that covers the electromagnetic actuator, and a bushing to which a cable is connected, and the surface of the insulating case and the surface of the mechanism case are electrically connected, and these surfaces are at the ground potential.SELECTED DRAWING: Figure 3

    【課題】開閉器ユニットにおいて、三重点が生じない構造とし、熱ストレスが加わる場合であってもクラックの発生を抑制する。【解決手段】固定電極と可動電極とを接離自在に配置した開閉器と、可動電極に接続された気中絶縁操作ロッドと、気中絶縁操作ロッドを駆動する電磁操作器と、開閉器を覆う絶縁ケースと、電磁操作器を覆う機構ケースと、ケーブルを接続するブッシングと、を備えた開閉器ユニットであって、絶縁ケースの表面と機構ケースの表面とが電気的に接続され、これらの表面が接地電位となるように構成されている。【選択図】図3
