Abstract

THE INVENTION PROVIDES A SWITCHGEAR HAVING AN INTERLOCK FUNCTION THAT A CIRCUIT BREAKER CANNOT MOVE TO THE CONNECTED POSITION SIDE WHEN AN EARTHING SWITCH IS IN A TURNING-ON STATE AT THE DISCONNECTED POSITION OF THE CIRCUIT BREAKER. WHEN A CIRCUIT BREAKER 11 IS AT THE DISCONNECTED POSITION, BY TURNING AN ES OPERATING MAIN SHAFT 22 TO TURN ON AN EARTHING SWITCH (ES) , AN ES INTERLOCK CAM 37 FIXED TO THE ES OPERATING MAIN SHAFT 22 IS TURNED, AN ES INTERLOCK LEVER 36 IS DRIVEN TO TURN IN COOPERATION WITH THIS TURNING OPERATION, A DRAW OUT DEVICE INTERLOCK FRAME 32 IS PRESSED TO MOVE, AND AN END THEREOF IS ENGAGED WITH A PROTRUSION 31 DISPOSED AT A MOVING SHAFT 25 OF THE DRAW OUT DEVICE TO INHIBIT THE ROTATION OF THE MOVING SHAFT 25.
