Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage cabinets, in particular to a low-cost and high-heat dissipation modular unit type low-voltage cabinet. Background Art

[0002] Low-voltage cabinet refers to the switch cabinet used in the low-voltage power distribution system, which is mainly used to distribute and control electric energy. It generally includes incoming switch cabinet, outgoing switch cabinet, capacitor switch cabinet, motor control cabinet, etc. The main function of the low-voltage cabinet is to distribute, protect, control and monitor the low-voltage power supply to ensure the safe and stable operation of the power system.

[0003] During operation, the current low-voltage cabinet is limited by the space inside the cabinet, and various components are densely arranged inside the low-voltage cabinet. Because the components will have energy loss in the form of heat during operation, the heat generated by the components in the low-voltage cabinet during operation is prone to accumulation. Therefore, the existing low-voltage cabinet is usually equipped with an active or passive heat dissipation mechanism to maintain the stability of the internal heat of the low-voltage cabinet and ensure the stable operation of the components. However, during the heat dissipation process, since the low-voltage cabinet is connected to the external space, the external air can easily carry dust into the interior of the cabinet, thereby causing certain interference to the normal operation of the components. In view of this, we propose a low-cost and high-heat dissipation modular unit low-voltage cabinet. Utility Model Content

In this process, the protective component 7 filters the dust carried in the air. After the air enters the receiving drawer 401, it can carry the heat generated during the operation of the components and dissipate it, thereby achieving the effect of cooling and dissipating the components. In addition, by arranging mutually on one side of the outer protective net 701 The overlapping and covering inner protective nets 1 703, 704, 705 and 706 are conducive to forming a multiple filtering protection structure at the opening position of the vent 1 403, that is, it is conducive to improving the filtering and protection effect on dust in the external air.
