Claims

[Scope of utility model registration request]

A lock plate is fixed to the floor of the power distribution board housing that houses the drawer type and disconnector, and a lock hole with a bottom surface higher than the floor is formed in the lock plate from top to bottom. The disconnector is equipped with a first lock pin extending vertically that can be raised and lowered to push it into the lock hole, and a handle lever is fixed to the first lock pin so that the lower end of the first lock pin is at the height of the bottom of the lock hole. When the vacuum interrupter in the drawer type or disconnector is in the position and the vacuum interrupter is turned on, one end substantially contacts the upper surface of the handle lever, and when the vacuum interrupter is suddenly disconnected, the intermediate part of the first lock lever is rotated. The second end is movably supported and the other end is connected to the movable lead rod of the vacuum interrupter, and the upper end is rotatably supported by a drawer or disconnector, and the lower end hangs down to prevent the handle lever from moving upward. A plug is provided with two lock levers and is detachable from a drawer type or disconnector from the horizontal direction, and a push rod that presses near the middle part of the second lock lever to turn the second lock lever into a non-vertical state only when the plug is attached, and a push rod located above or above. A hook having a concave portion opening downward is provided, and a rotating plate rotatably provided on a drawer or disconnector is interlocked and connected to the first lock pin, and the lower end of the first lock pin is at the uppermost position or in the lock hole. An interlock device for a drawer type or disconnector, characterized in that a second lock pin that fits into the recess of the hook only when it is in the bottom position is fixed to the rotating plate.
