Take the prefabricated cabin secondary combination equipment as an example. It is composed of prefabricated cabins, secondary equipment cabinets, secondary equipment, etc. The whole set of equipment is integrated by the manufacturer, and the assembly and wiring are completed in the factory. It is transported to the installation site as a whole and installed by a crane on the previously built base to connect the equipment and lines. This is the formation of the so-called modular prefabricated cabin.

The utility model has the advantage of good heat dissipation effect, but for the pre-installed substation in the above technical solution and the existing substation, in order to prevent external objects from hitting the substation box during use, more protective fences are usually installed on the outside for protection. However, during the use of such protective facilities, since they are installed on the periphery of the substation, operations such as drilling and inserting piles are required, and the steps are very troublesome, and the area occupied is large, and it is not easy to disassemble in the later stage, which reduces the convenience of using the device.

[0008] In one example, a heat dissipation groove is opened in the middle position of the bottom of the top plate, and the inner wall of the heat dissipation groove is connected to the interior of the prefabricated cabin of the substation.
