The invention discloses a distribution network electric cabinet and a control system thereof, comprising a cabinet body, a partition plate, a base, a thermal fan, a heating pipe and a flow guiding device. The invention has the beneficial effect that, At first, by arrange that heating tube under the hot fan, As that distribution cabinet can be heat dissipated in sum, and the distribution cabinet can be heated in winter, Secondly, by configuring the shutter and the spherical arc groove, the air inside the cabinet is guided, ensure that heat is dissipated and heated everywhere in the distributioncabinet, Ensure the safe operation of the equipment, In addition, the air guide plate can make the air in the cabinet form eddy current, prolong the stay of the hot air in the cabinet through the collision between the different eddies, ensure the heating effect and achieve a certain heat preservation effect, and finally, the base keeps the cabinet body and the ground at a certain distance, so that the natural air can pass through the bottom surface of the cabinet body and improve the heat dissipation capacity of the cabinet body.
