Claims

[Scope of utility model registration request]

It has a vacuum container made of an insulator and a metal container, and an electrode that is placed in the vacuum container and moves toward and away from the vacuum container, and a part of the metal container is configured to surround the electrode and surround the electrode. A vacuum interrupter is provided in which a portion of the metal container is covered with a first insulating layer and the other portion of the metal container is covered with a second insulating layer, and the vacuum interrupter is surrounded through a gap. In a vacuum breaker configured to include an insulating frame, and a lead-out conductor electrically connected to the electrode and fixed to the insulating frame, the vacuum breaker is located between the lead-out conductor and the insulating frame, and the vacuum incrector. An insulating barrier is provided, and the insulating barrier is composed of a plate interposed between the lead-out conductor and the vacuum interrupter, and a cylindrical part having one end fixed to the plate part, and the cylindrical part is connected to the lead-out conductor side. and a first insulating layer in the vicinity of at least a lap portion between the second insulating layer and the first insulating layer. Vacuum breaker.
