High-voltage power distribution cabinet with good heat dissipation performance

Abstract

The invention provides a high-voltage power distribution cabinet with good heat dissipation performance, belongs to the technical field of high-voltage power distribution cabinets, and aims to solve the problem that the service life of electronic components in the high-voltage power distribution cabinet is shortened due to the fact that heat dissipation holes in an existing high-voltage power distribution cabinet are easily blocked by external flying dust. The cabinet comprises a cabinet body, the top of the cabinet body is provided with a rain shielding mechanism, the right end face of the cabinet body is fixedly provided with a labor protection storage mechanism and a control box, and the left end face of the cabinet body is provided with a cleaning mechanism at the heat dissipation holes. After a human body induction switch induces a human body, a cleaning motor is started through a control box, then a second driving belt wheel is driven to rotate through a rotating shaft of the cleaning motor, then a second driven belt wheel is driven to rotate through a belt, and then a cleaning brush is driven through the upper end of a connecting rod to do up-down reciprocating cleaning motion at heat dissipation holes formed in the rear end face of the cabinet body. Therefore, the heat dissipation effect in the high-voltage power distribution cabinet is not affected, and the service life of electronic components in the high-voltage power distribution cabinet is prolonged.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power distribution cabinets, and more specifically relates to a high-voltage power distribution cabinet with good heat dissipation performance. Background technique [0002] Power distribution cabinet: It is the collective name of the motor control center. The power distribution cabinet is used in occasions where the load is relatively scattered and there are few circuits. Generally, we see that the distribution cabinets are installed in relatively hidden corners. The high-voltage power distribution cabinet refers to electrical products with a voltage level of 3.6kV~550kV that are used for on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. [0003] For example, application number: CN201910863761.2 The present invention discloses a high-voltage power distribution cabinet, including a mounting plate, a side plate rotata...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a high-voltage power distribution cabinet with good heat dissipation performance, so as to solve the problem that although there are cooling holes on the rear wall of the existing high-voltage power distribution cabinets, the cooling holes are easily damaged. If it is blocked by flying dust from the outside, once it is blocked, it will affect the heat dissipation effect inside the high-voltage power distribution cabinet, thereby reducing the service life of the electronic components inside the high-voltage power distribution cabinet; and due to the lack of effective warning structure on the existing high-voltage power distribution cabinet, When the maintenance personnel open the cabinet door to maintain the inside of the cabinet, some maintenance personnel will forget to wear safety measures such as labor insurance and cause safety accidents, thereby reducing the safety of the high-voltage power distribution cabinet during maintenance; and the existing outdoor high-voltage Although there is a rain-shielding structure on the top of the power distribution cabinet, the leak hole on the rain-shielding structure is easily blocked by fallen leaves and other debris from the outside. Rainwater flows into the cabinet along the gap, thus reducing the service life of the high-voltage power distribution cabinet
