[0002] Power equipment refers to various equipment used for power generation, transmission, transformation, distribution and consumption in power systems; low-voltage distribution cabinets play an important role in the process of power distribution. Low-voltage distribution cabinets will generate heat during operation, which will cause the temperature inside the low-voltage distribution cabinet to rise, resulting in untimely heat dissipation of electrical components and even damage to electrical components. Therefore, a cooling structure will be installed on the low-voltage distribution cabinet to cool the inside of the low-voltage distribution cabinet and reduce the adverse effects of high temperature on electrical components.

[0003] After searching, a cooling structure for electrical components of a high and low voltage distribution cabinet is disclosed in the patent document with patent announcement number CN213753700U. Aiming at the problem of low heat dissipation efficiency of high and low voltage distribution cabinets in the prior art, the following scheme is proposed, which includes a cabinet and a heat dissipation mechanism installed inside the cabinet, characterized in that a top cover is fixed on the top of the cabinet, an opening is provided on the front of the cabinet, a cabinet door is hinged on one side of the opening, an air inlet is provided on one side of the outer wall of the cabinet, a filter is fixed inside the air inlet, and a plurality of heat dissipation holes are provided on the inner wall of the cabinet opposite to the air inlet; the heat dissipation mechanism includes two threaded columns rotatably installed on the inner wall of the bottom of the cabinet, a moving block threadedly connected to the two threaded columns, and a fan installed between the two moving blocks.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The existing cooling structure of electrical components in high and low voltage distribution cabinets, during use, starts the transmission motor to make the fan move up and down, increasing the air cooling range of the electrical components inside the cabinet, which is beneficial to improving the air cooling effect of the electrical components, but it is not convenient to clean the blockage on the filter, which will reduce the ventilation effect of the filter and the heat dissipation effect of the electrical components inside the cabinet;

The existing cooling structure of the electrical components of the high and low voltage distribution cabinet is used to connect the fan and the moving block through the provided connecting blocks, connecting grooves and fixing bolts during use, so as to facilitate the control of the transmission motor to drive the fan to move. However, in the process of disassembling and assembling the fan, multiple fixing bolts need to be disassembled and assembled, and even the thread hair may be stuck, which brings inconvenience to the disassembly and assembly of the fan and reduces the disassembly and assembly efficiency of the fan.

[0007] To this end, we provide a cooling structure for electrical components of a low-voltage distribution cabinet to solve the above-mentioned problems. Utility Model Content
