Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the high internal temperature of the current high-voltage power distribution cabinet is likely to cause fires, and the power distribution cabinet is a place where fires frequently occur in the entire power grid system, and the high internal temperature of the power distribution cabinet is more likely to cause aging of components and reduce the use of Therefore, the heat dissipation problem of the power distribution cabinet needs to be solved urgently; in order to solve the heat dissipation problem, many heat dissipation holes are often installed on the power distribution cabinet, but too many heat dissipation holes are easy to enter the rainwater, and when the rainstorm comes, the water on the ground is very deep, and the ground area Water easily enters the inside of the power distribution cabinet through the gap in the door of the power distribution cabinet or through the ventilation and cooling holes.
Some existing power distribution cabinets solve the heat dissipation by blowing air into the inside of the power distribution cabinet to dissipate heat through the flow of air, but when the blower blows the air outside the power distribution cabinet into the cabinet, it is easy to bring in a lot of dust , the dust is scattered on the components inside the cabinet, which greatly reduces the service life of these components

Abstract

The invention discloses a high-voltage power distribution cabinet having waterproof heat-dissipation dustproof performance. The high-voltage power distribution cabinet comprises a cabinet body, wherein the cabinet body consists of a left side plate, a right side plate, a top plate, a base plate, a rear plate and a cabinet door, the cabinet door is formed in the front portion of the cabinet body. The high-voltage power distribution cabinet further comprises a semi-circular rain-sheltering canopy, a bucket-shaped waterproof device, four transverse partition plates, a temperature sensor, a controller, an air blower and a dust filtering device, wherein the temperature sensor is arranged inside the cabinet body, a temperature signal acquired by the temperature sensor is input to the controller, and the controller controls start and stop of the air blower. By means of the high-voltage power distribution cabinet, the water proofing, heat-dissipation and dust proofing problems are effectively solved.
