[0005] At present, low-voltage power cabinets are often installed outdoors, such as on both sides of municipal roads. In rainy and foggy weather, due to the adhesion of the side of the cabinet, some water droplets will adhere to the outdoor power cabinets. If the rainwater cannot be wiped off in time after the rain, the outer wall of the power cabinet is easily corroded by liquid; the inside of the power cabinet does not have moisture-proof capability, and the temperature difference between inside and outside is prone to condensation, which makes the equipment wet and leaves a safety hazard; the humidity in rainy and snowy weather is high , if humid air enters the heat dissipation holes, it is also prone to corrosion; in dry weather, the cabinet body is prone to static electricity, if it cannot be removed in time, it will also be rusted under the action of electrostatic force, and high temperature exposure weather not only affects the power cabinet shell The service life of the body, and the equipment in the power cabinet is subjected to the heat transfer of the shell and also the heat radiation, which causes the equipment in the power cabinet to not dissipate heat quickly, resulting in potential safety hazards

Abstract
The invention discloses a moisture-proof and sun-proof outdoor low-voltage power cabinet. The moisture-proof and sun-proof outdoor low-voltage power cabinet comprises a double-layer cabinet body, a protective shed arranged on the top of the double-layer cabinet body, a moisture-proof layer arranged between double layers of the double-layer cabinet body and a ventilation component arranged on the double-layer cabinet body; the double-layer cabinet body comprises an outer cabinet body and an inner cabinet body fixed inside the outer cabinet body; and four corners of the interior of the outer cabinet body are fixed to the four corners of the exterior of the inner cabinet body through L-shaped fixed parts. The moisture-proof and sun-proof outdoor low-voltage power cabinet is reasonable in structure and convenient to use, the temperature of equipment inside the inner cabinet body is adjusted, and the humidity of power equipment is dried, so that the effect of protecting the power equipmentinside the inner cabinet body is reached. A shade is formed by the tower-type protective shed, the direct sunshine area of the power cabinet body is reduced, and the service life is prolonged. Electric energy is provided for a warm air machine by using green solar energy, the waste of energy sources is reduced, the requirement of the warm air machine on energy sources also can be met, and ventilation is provided for the power equipment inside the cabinet body.
Description
technical field [0001] The invention relates to the technical field of electric equipment, in particular to an outdoor low-voltage power cabinet that is moisture-proof and sun-proof. Background technique [0002] Electricity is an energy powered by electric energy. It was invented in the 1870s. The invention and application of electric power set off the second industrialization climax and became one of the three scientific and technological revolutions in the world since the 18th century in human history. Since then, technology has changed people. Electric power is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution, and power consumption. It converts primary energy in nature into electricity through mechanical energy devices, and then passes through power transmission, power transformation, and power distribution. To supply power to various users, power distribution equipment is a general term ...
