When the line needs to be repaired, the personnel first insert the key column 33 into the keyhole through the rib plate 37, and then rotate the key column 33 through the rib plate 37. The rotation of the key column 33 drives the locking column 32 to rotate, and the rotation of the locking column 32 drives the connecting plate 34 to rotate, so that the torsion spring 35 is elastically stretched. At the same time, the rotation of the locking column 32 drives the insulating rib 3, and the insulating rib 3 toggles the switch valve upward. , so that the isolating switch 6 is opened, thereby preventing the primary circuit of the high-voltage switch cabinet from being in a high-voltage energized state, and putting the equipment in a locked and operation-free state. When the force applied to the key column 33 through the rib plate 37 ends, the elastic force of the torsion spring 35 drives the connecting plate 34 to rotate in the opposite direction, and the reverse rotation of the connecting plate 34 drives the locking column 32 to rotate in the opposite direction, and then drives the insulating rib 36 to rotate in the opposite direction. At the same time, the key column 33 rotates in the opposite direction to realize the resetting of the locking mechanism 3, and then the personnel opens the cabinet door 2 through the handle to carry out equipment maintenance work.
