[0002] High-voltage power distribution cabinets are crucial equipment in power systems, mainly used for power distribution, control, and protection. Its main function is to distribute high-voltage electrical energy from power plants or substations and ensure the safe and stable operation of the power system through various protection devices. High-voltage power distribution cabinets are widely used in various fields such as industry, commerce, and civil buildings, and are key equipment to ensure power supply and electrical safety.

[0003] Traditional high-voltage power distribution cabinets use a single cavity structure, which has high electrical safety risks, difficult maintenance and repair, poor heat dissipation performance, and electromagnetic interference. In addition, when an electrical fault or short circuit occurs inside the high-voltage power distribution cabinet, it is easy to cause a fire. When a fire occurs in a traditional power distribution cabinet, due to the lack of effective isolation measures, the fire is easy to spread to the external environment, leading to more serious safety accidents. This not only causes devastating damage to the power distribution cabinet itself, but also poses a significant threat to surrounding equipment, personnel safety, and the continuous operation of the power system. SUMMARY

[0060] A plurality of heat dissipation holes 22 are opened on both sides of the cabinet body 1, and a dustproof shell 23 is fixed outside the heat dissipation holes 22; a ventilation groove 24 is opened at the bottom of the dustproof shell 23; a filter screen 25 is movably placed outside the heat dissipation hole 22, and a connecting plate 26 is fixed at the bottom of the filter screen 25; a positioning frame 27 is fixed on one side of the connecting plate 26.

[0061] In combination with the accompanying drawings Figure 1and the accompanying drawings Figure 10 As shown in the drawings, the bottom of the cabinet 1 is provided with a positioning groove 28, and a positioning strip 29 is movably connected inside the positioning groove 28. One side of the positioning strip 29 is fixed with a mounting strip 30, and the mounting strip 30 and the surface of the cabinet 1 are both provided with threaded holes 31. The threaded holes 31 are internally threadedly connected with bolts 32. The side of the positioning strip 29 away from the mounting strip 30 is fixed with a baffle 33, and the positioning frame 27 is located between the baffle 33 and the outside of the cabinet 1. The top of the partition box 10 is fixed with a first air pipe 34, and one end of the first air pipe 34 is fixed with an air pump 35. The first air pipe 34 penetrates the through hole 6. The input end of the air pump 35 is fixed with a second air pipe 36, and one end of the second air pipe 36 is fixed with a carbon dioxide storage tank 37.

[0062] The top of the partition box 10 is fixed with a pressure sensor 38, and the inner wall of the partition box 10 is fixed with a temperature sensor 39.

[0063] Firstly, the cabinet 1 is placed in a suitable position, and the positioning strip 29 is placed into the positioning groove 28 at the bottom of the cabinet 1. At this time, the filter screen 25 is just clamped outside the heat dissipation hole 22. After adjusting the position, the mounting strip 30 and the threaded holes 31 on the surface of the cabinet 1 are fixed by using the bolts 32 to stabilize the positioning frame 27. At this time, the positioning frame 27 is located between the baffle 33 and the outside of the cabinet 1, and the installation of the filter screen is completed. In this way, both ventilation and heat dissipation can be ensured, and dust can be prevented from entering the inside of the cabinet. During daily maintenance, the filter screen 25 can be conveniently taken down for cleaning or replacement by disassembling the bolts 32 and taking out the positioning strip 29, so that the ventilation effect of the heat dissipation hole 22 is not affected. The filter screen 25 is arranged outside the heat dissipation hole 22, which can effectively intercept dust, impurities and other particles in the air. During the operation of the power distribution cabinet, a large amount of air will enter and exit the cabinet 1 through the heat dissipation hole 22. If there is no filter screen 25, dust is easy to enter the inside of the cabinet and accumulate on the power distribution box 2 and other electrical elements. Dust accumulation may affect the heat dissipation performance of the electrical elements and may also cause short circuit of the elements. The filter screen 25 can prevent dust from entering, ensure that the internal elements are in a clean environment, and ensure the stable operation of the power distribution cabinet.
