For example, the patent with the announcement number CN210430532U includes a movable connected cabinet door, a handle and an electric button are arranged on the front side of the cabinet door, a lock hole part matched with the cabinet door is arranged in the interior of the cabinet body, and an electric lock mechanism matched with the lock hole part is arranged. The electric lock mechanism includes a lock shell, a bolt and a motor. Through the driving of the motor, the bolt can be reversely rotated in the bolt cavity in the lock shell, so as to realize the closing and locking of the cabinet door. The device has simple structure, convenient operation, can save time, and can enhance the safety protection function through secondary locking.

[0004] However, the existing high-voltage switch cabinet mostly depends on manual opening of the cabinet door, especially in emergency situations, the staff needs to manually open the cabinet door, which not only wastes time, but also may have certain safety hazards. In the process of maintenance and repair of high-voltage power equipment, the staff often needs to react quickly, but when manually operating the cabinet door, the best opportunity is often missed, and unnecessary danger may be caused by improper operation.

[0005] Although the prior art has made efforts to improve the safety of the switch cabinet, there are still problems of frequent manual operation and low efficiency. Especially in high-voltage environment, the operation of opening the cabinet door may increase the risk of personnel due to excessive dependence on manual operation. UTILITY MODEL CONTENTS
