[0002] An electrical installation cabinet refers to a protective cabinet used to install and place electrical equipment. It plays the role of protecting electrical equipment. Since the electrical equipment in the electrical installation cabinet will generate more heat when working, in order to facilitate heat dissipation, more ventilation holes are usually opened on the electrical installation cabinet. However, more holes will easily lead to more dust entering the electrical installation cabinet, which will cause pollution to the electrical equipment inside. Therefore, it is necessary to set up a dustproof mechanism in the electrical installation cabinet to clean the dust.

[0003] When using an electrical installation cabinet, a filter plate is generally installed at the vent. The function of this filter plate is mainly to prevent dust from entering the cabinet. However, this filter plate has limited dust prevention effect. In addition, the electrical equipment needs to be placed inside the filter frame during use. When cleaning the filter frame, the electrical equipment and the filter frame need to be taken out in turn. After cleaning, they need to be placed again.

There are two ventilation components. The symmetrically arranged ventilation components can form stable convection of air inside the cabinet. The airflow can flow evenly through various parts under the action of the symmetrical ventilation components, effectively preventing local overheating of the cabinet and improving the heat dissipation efficiency. At the same time, the symmetrical layout can evenly distribute the pressure on the cabinet and improve the structural stability of the power distribution cabinet. The two ventilation components are respectively arranged on two adjacent surfaces of the cabinet door; Among them, the ventilation component includes a fixed frame, which is fixedly installed on the outside of the cabinet body, and a partition is fixedly connected to the middle of the inner wall of the fixed frame. An annular hole is opened on the outside of the partition, and the annular holes are evenly distributed on the dustproof plate, so that the air flow in the distribution cabinet is more balanced and local overheating is avoided. Compared with the traditional single vent, the layout of the annular holes can make the heat dissipated more evenly, and the heat dissipation efficiency is improved. The center line of the annular hole is vertically arranged, and the number of the annular holes is several, and the several annular holes are evenly arranged on the outside of the partition.
