PROBLEM TO BE SOLVED: To improve movement of a breaker body simply into an electrically operated type even in an existing breaker shifter for an enclosed switchboard having no long- sized space in a front, by effectively utilizing the dead space of the enclosed switchboard rationally without requiring large remodeling and resulting in scaling-up. SOLUTION: An electrically operated shifter 4 having a U shape in a plan view consisting of two speed reducers 6, 6, comprising a motor 5, a couple of decelerators 6 disposed at both sides in the cross direction of a breaker body 1 and being mutually interlocked through a connecting shaft 8 for decelerating the rotation of the motor 5, two jacks 7, 7 disposed on both sides in the cross direction of the breaker body 1 and reciprocated along the moving direction of the breaker body 1, and breaker moving metal fittings 15 fixed and coupled over a section between movable embers 7B, 7B of these two jacks 7, 7 while being bonded and connected for integral movement with the breaker body 1, is arranged and fastened onto the floor face of an enclosed switchboard 2 on the rear side of the breaker body 1. An electrically operated type enclosed switchboard is so improved as to be capable of moving the breaker body 1 to the place of connection and the place of disconnection by electric power through the electrically operated type shifter 4. |
