Claims

[Scope of utility model registration request]

The lower contacts of the 1000 sets of disconnecting contacts installed above and below the pull-out path of the breaker placed on the base and guided so as to be freely pulled out, and the lower contacts of the 1000 sets of disconnecting contacts installed near the front side of the 1000 sets of the disconnecting contacts. In the grounding device, the grounding device includes a grounding potential drive shaft which is pivoted horizontally and at right angles to the drawing direction of the container and is integrated with the lower contact and a rod-shaped movable contact that can be brought into and out of contact with the lower contact. a rectangular movable arc contact rotatably supported on a rod-shaped portion thereof so as to be rotatable in the same direction as the contact; a fixed arc contactor having a closed holding groove until the contact and the lower contact reach a predetermined opening distance; 1. A grounding device for a disconnecting contact for a draw-out type breaker, characterized in that it is provided with a quick-cutting mechanism that allows the arc movable contact to be quickly disconnected and to be able to recover after disconnection.
