Safety high-low voltage distribution cabinet

Abstract

The invention discloses a safety high-low voltage distribution cabinet comprising a cabinet body which is internally provided with a mounting cavity. The two sides of the cabinet body are respectivelyprovided with a door body mounting cavity which is internally provided with two door plates. One end of each door plate is hinged with the cabinet body, and the other side of each door plate is sucked and fixed with each other by an electromagnetic lock. An elastic mounting plate is vertically arranged in the cabinet body close to the door plate. The bottom side of the elastic mounting plate is bent and fixed on the inner wall of the mounting cavity of the cabinet body. A dust prevention device is arranged on the inner side of the door plate near the root of the elastic mounting plate in a protruding way. When two adjacent door plates are sucked together, the inward protruding dust prevention devices eject out the elastic mounting plates to be inclined. The cabinet has extremely high heatdissipation performance and uses the inclined air guide structure for passages of all the fresh air through the power distribution module to realize rapid and orderly high-efficiency heat dissipationand also has good fireproofing performance so as to solve the problem of the fire of the power distribution cabinet and further facilitate 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
