High-heat-dissipation management cabinet for electric power distribution network

The invention discloses a high-heat-dissipation management cabinet for an electric power distribution network, and the cabinet comprises a main body unit, a positioning unit disposed at the top of a main body part, and a plurality of equipment storage units disposed on the positioning unit. The main body unit comprises a base, a positioning plate and a top plate, and the central position of the rear side of the top of the base is vertically provided with the positioning plate. A U-shaped pipe at the bottom of a base is inserted into the ground, the stability of the invention is improved, air holes are uniformly formed in the middle of the U-shaped pipe, water in the ground can enter the U-shaped pipe through the air holes and be stored by water retained particles, a fan rotates to suck humid and low-temperature air in the U-shaped pipe into the moisture cavity, moisture is removed through the moisture absorption cotton and then enters the fixing pipe, due to the fact that the fixing pipe is communicated with
