摘要： In an enclosed switchboard in which a circuit breaker in a cubicle is drawn out from or pushed in toward a disconnecting switch, a controlling circuit housed in the cubicle for supplying a signal to the driving device of the circuit breaker and for transmitting a signal relating to the state of the circuit breaker to an external circuit. The controlling circuit is provided with a position switch which responds to the position of the circuit breaker, and two contactors which are constituted so as to be contacted with a contactor mounted on the circuit breaker in the connecting and the testing positions of the circuit breaker.

摘要： An enclosed electrical switchboard, in which a circuit breaker including a movable contact is drawn out from or pushed in toward a stationary contact of a disconnecting switch, is provided with a cover for covering the stationary contact of the disconnecting switch. The cover is provided with a window facing the stationary contact, and a shutter cover is provided to close the window. A mechanism moves the shutter cover to close or clear the window in accordance with the draw out and push in movements of the circuit breaker.

摘要： An enclosed switchboard in which an upper chamber and a lower chamber are formed within a switchboard frame in the form of a box for accommodating electrical apparatus such as circuit breakers. At the free surfaces of the frame facing the two chambers a top level door and a bottom level door facing the two chambers are mounted so as to be capable of being opened and closed separately from one another. A middle level door for the mounting of instruments is mounted between the top level door and bottom level door, and instruments needed for regular inspection and control, for instance meters, operating switches, indicator lamps and the like, are mounted on the door surface of the middle door.
