However, since the power distribution components and circuit board welded in the box are difficult to remove and the space inside the protective box is limited, it is difficult to repair the power distribution components when they fail. In view of this, we propose a power protection structure for a power DC panel. Utility Model Content

[0029] Embodiment 2:

[0030] As shown in the attached figure of the instruction manual Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a power protection structure for a power DC screen is used. When in use, the controller 9 is used to control the cooling fan 12. The wind blown by the cooling fan 12 dissipates the heat inside the inner box 11.
