Safety high and low voltage power distribution cabinet

Abstract

The invention discloses a safe high and low voltage power distribution cabinet, which comprises a cabinet body. The interior of the cabinet body has an installation cavity. Two door body installation cavities are respectively provided on both sides of the cabinet body. Two door panels are installed in the door body installation cavity. , one end of the door panel is hinged with the cabinet body, and the other side of the door panel is fixed by mutual attraction through an electromagnetic lock. An elastic mounting plate is vertically arranged inside the cabinet close to the door panel, and the bottom side of the elastic mounting plate is bent and fixed on the cabinet On the inner wall of the installation cavity of the body, a dust-proof device is protruded from the inner surface of the door panel close to the root of the elastic installation plate. When the two adjacent door panels are closed, the inwardly convex dust-proof device pushes the elastic installation plate out and closes it. It is inclined, and the invention has very good heat dissipation performance. It adopts an inclined air guide structure to pass all the fresh air through the power distribution module for fast, orderly and efficient heat dissipation. problems, and more convenient maintenance.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a safe high and low voltage power distribution cabinet. Background technique [0002] The existing high and low voltage power distribution cabinets generally include a cabinet body, a cabinet door, and a power distribution module installed in the cabinet. Since the power distribution modules are all fixedly installed on the framework inside the cabinet, the power distribution module The heat between the groups is concentrated, and a large amount of heat energy is generated during work. The heat energy is extracted by the negative pressure fan, but due to the unreasonable structural design, the airflow is chaotic inside, and the heat dissipation effect is not uniform, resulting in general heat dissipation performance and reducing the overall use. life; [0003] In addition, due to the use of negative pressure fans, air intake filters are installed on the cabinet body.

Problems solved by technology

[0002] The existing high and low voltage power distribution cabinets generally include a cabinet body, a cabinet door, and a power distribution module installed in the cabinet. Since the power distribution modules are all fixedly installed on the framework inside the cabinet, the power distribution module The heat between the groups is concentrated, and a large amount of heat energy is generated during work. The heat energy is extracted by the negative pressure fan, but due to the unreasonable structural design, the airflow is chaotic inside, and the heat dissipation effect is not uniform, resulting in general heat dissipation performance and reducing the overall use. life;

[0003] In addition, due to the use of negative pressure fans, air intake filters are installed on the cabinet body. These air intake filters often adhere to a large amount of dust, making cleaning difficult;

[0004] Moreover, since the power distribution cabinet is in the working state for a long time, there are often combustion problems caused by overheating and spontaneous combustion or other reasons, resulting in the burning of the entire power distribution cabinet, causing serious economic losses and affecting power consumption;

[0005] Since the power distribution cabinet is equipped with a large door body, it is necessary to open the door body during inspection and maintenance. At this time, all power distribution modules will be exposed, but in this case, it is generally not necessary to expose them all, so outdoor inspections are performed in rainy days It is particularly inappropriate when it is used, it is easy to short circuit due to water ingress, or it will damage other good power distribution modules due to misoperation of maintenance tools;

[0006] Finally, due to the large number of power distribution modules and their close proximity, the heat transfer between them is rapid and the mutual influence is large. The power distribution modules are located in a closed environment, and the light is not good during maintenance, which is not conducive to maintenance
