Working principle: when the sliding block is to be reset, the reset rod is pressed down, so that the large sliding block and the small sliding block slide in opposite directions. The sliding of the large sliding block mainly plays a role in yielding, so that the reset rod has a larger downward stroke. The small sliding block slides to drive the lifting frame to be lifted by the linkage rod. After the small sliding block slides in place, the lower end of the lock catch slides into the second positioning groove of the tripping sliding sheet, the upper end of the lock catch is inserted into the first positioning groove of the small sliding block, locking is completed, and the lifting frame after lifting is fixed. And the lifting frame is lifted to drive the movable contact piece to lift at the same time, so that the movable contact piece contacts with the static contact piece, and finally, the reset operation is finished. When the electromagnetic tripping mechanism receives a tripping signal, the movable iron core of the electromagnetic tripping mechanism retracts to pull the tripping sliding sheet outwards, so that the lower end of the lock catch leaves the second positioning groove of the tripping sliding sheet, and meanwhile, the lock pin at the upper end of the lock catch also leaves the first positioning groove of the small sliding block, thereby completing unlocking, and at the moment, the movable contact and the lifting frame return to the original positions to realize tripping. After the tripping is finished, the movable iron core is reset through a fourth reset spring, and the reset of the movable iron core drives the reset of the tripping sliding sheet to wait for the next reset operation.
