Substations are usually located at the node of the power transmission and distribution network to achieve the transmission, distribution and control of electric energy. They play an important role in the power system to ensure the safe, stable and efficient transmission and distribution of electric energy.

[0003] After searching, it was found that the substation in the prior art, such as a prefabricated substation disclosed in publication number CN216312521U, can quickly introduce the heat in the prefabricated substation body into the water circulation heat dissipation pipe with the cooperation of the heat absorption plate and the heat conductive sheet, and drive the aqueous solution to circulate in the water circulation heat dissipation pipe for cooling through the circulating water pump. At the same time, the water storage tank collects rainwater to keep the aqueous solution in the water circulation heat dissipation pipe sufficient.
