The operation principle of the switching off/on device is specially：When needing to carry out sub-switching operation, the motor drives worm screw
Rotate to drive worm gear to be reversely rotated, worm gear, which reversely rotates, can cause the connecting rod left-hand for engaging connection movement, even
The mobile of extension bar can drive catch bar to move, and because linear chute defines that catch bar can not be moved left and right, promote
Bar and connecting rod be hinged, then under the limition orientation of linear chute, the left-hand of connecting rod is moved be converted into catch bar along
The slide downward of linear chute, the gangbar for being right against linear chute notch design can be promoted during catch bar slide downward, linked
Bar and then driving breaker open operation, realize sub-switching operation；When needing to carry out closing operation, motor driving worm screw rotate with
Drive worm gear rotated forward, and it is foregoing similarly, worm gear rotate forward can so that engage connection connecting rod dextrad move
It is dynamic, under the limition orientation of linear chute, the dextrad movement of connecting rod is converted into catch bar sliding up along linear chute
Dynamic, catch bar is away from the gangbar for being right against linear chute notch design, while worm gear rotates forward can drive worm gear projection just
To rotation, when worm gear is raised to be abutted with the transmission boss of dish type driving member, worm gear is raised to drive dish type driving member to rotate, dish type
Driving member is rotated to drive combined floodgate axis of rotation, combined floodgate rotating shaft and then the divide-shut brake handle rotation of drive breaker to realize conjunction
Lock, realize closing operation.
A kind of breaker, including at least one breaker body and foregoing switching off/on device, the switching off/on device driving
