The method according to claim 8, wherein in step 300, each group of distribution cabinets are distributed in parallel from inside to outside, each distribution cabinet opens the sliding plate in sequence according to the respective operating temperature to dissipate heat, and the specific implementation steps for the heat dissipation operation of the single distribution cabinet are as follows:
determining a power distribution cabinet with the temperature exceeding the safety range, and pulling a sliding plate on the back of the power distribution cabinet outwards by a distance equal to the thickness of the sliding plate;
the sliding plates are pulled along the moving direction and are stacked on the outer surfaces of the sliding plates of the adjacent power distribution cabinets, and when the temperature is reduced to a safe range, the stacked sliding plates are shifted inwards to reset;
when the temperature of the power distribution cabinet positioned on the inner side of the stacked sliding plates exceeds the safety range and at least one power distribution cabinet is away from the stacked sliding plates, the stacked sliding plates are shifted inwards to reset, and then the sliding plates of the power distribution cabinets with the temperature exceeding the safety range are stacked in sequence.
10. The method of claim 8, wherein in step 400, when the operation temperature of the outermost switch board exceeds the safety range, the extension panel is rotated to be parallel to the back surface of the switch board, and the sliding plate of the outermost switch board is transferred to the extension panel.
