[0013] A power theft prevention metering cabinet for power transmission, the method of use is as follows: when it is necessary to control the cabinet door to open, an external split control device is used to drive the first electric push rod to extend so that it opens the cabinet door, rotates it to a state parallel to the inside of the partition, and then a driving motor drives the screw to rotate so that it drives the threaded block and one side of the cabinet door to move toward the inside of the partition until the cabinet door is completely moved to the inside of the partition, completing the opening of the cabinet door.

[0017] 2. The inner layer is sealed by the first sealing gasket and the second sealing gasket to prevent the entry of external dust. The heat is then absorbed and transferred to the inside of the interlayer by means of heat transfer using the heat conduction plate, the cooling sheet, the heat conduction rod and the heat dissipation fins. The heat dissipation fan then ventilates and dissipates the inside of the interlayer, thereby achieving the purpose of heat dissipation. While ensuring heat dissipation, the entry of external dust when the cabinet door is closed is effectively prevented.

[0018] 3. By using a movable connecting seat to movably connect the cabinet door with a movable threaded block, the cabinet door can be stored inside the compartment after it is opened, thereby facilitating the staff to disassemble and repair the parts inside the inner layer, improving its convenience, and avoiding the cabinet door from shaking during the staff's maintenance process, causing the cabinet door to close accidentally, affecting the staff's operation.
