The invention relates to the technical field of high-voltage cabinets, in particular to an energy-saving and heat-dissipating high-voltage cabinet, comprising a cabinet body, two long pillars and two short pillars, wherein the two long pillars and the two short pillars are both connected to the cabinet body, and the cabinet body passes through The two thrust bearings are connected with a vertical shaft, and the vertical shaft is connected with a plurality of driving sleeves and a plurality of driving strips. The vertical shaft is connected with a plurality of fan blades through an installation ring, and the installation ring is connected with a traction mechanism. The traction mechanism is close to the two thrust bearings. A tension spring is connected between the thrust bearings on the upper side, an annular filter dust-proof plate and a back plate are installed in the cabinet, two long and two short columns are connected with an inclined frame, and the long and short columns are connected by a wing bracket. The fan-shaped bracket, the wing bracket is connected with the traction mechanism, the solar panel is installed on the back plate, the inclined frame, the wing bracket and the fan-shaped bracket, the battery and the generator are installed in the cabinet, and the cabinet is connected with two installation door mechanisms, which are relatively Energy saving, clean use, stable heat dissipation, and more practical.
