Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet equipment technology, specifically to a low-voltage switchgear with a dehumidification structure. Background Technology

[0002] In the field of power equipment, low-voltage switchgear, as an important component of the power system, undertakes key tasks such as power distribution, control and protection. The electrical equipment installed inside it has strict requirements for the operating environment.

[0003] Traditional low-voltage switchgear mostly relies on fluid exchange with the outside air for heat dissipation and moisture protection, such as by setting up ventilation openings or using an external circulation cooling system. However, this method has many drawbacks. Dust and impurities in the outside air can enter the switchgear body with the airflow and adhere to the surface of the electrical equipment. This not only affects the heat dissipation performance of the equipment, causing the equipment temperature to rise and accelerate aging, but may also cause faults such as short circuits. At the same time, corrosive gases in the outside air can also corrode the electrical equipment, damaging the insulation performance and mechanical strength of the equipment and shortening its service life.

[0004] In addition, in humid environments, moisture can easily enter the switch cabinet body through ventilation openings, causing electrical equipment to become damp, leading to problems such as decreased insulation performance, rust and corrosion, which seriously affect the safe and stable operation of the equipment.

[0005] To address this issue, we propose a low-voltage switchgear with a dehumidification structure. Utility Model Content

[0006] The purpose of this invention is to provide a low-voltage switchgear with a dehumidification structure to address the aforementioned shortcomings in the technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage switchgear with a dehumidification structure, comprising a switchgear body, hollow plates installed on the inner walls of both sides of the switchgear body, circulation holes evenly distributed on the outer walls of the hollow plates, a cooling box and a drying box fixedly installed on the top outer wall of the switchgear body, air guide pipes connected to one side of the outer walls of the two hollow plates through openings, the other ends of the two air guide pipes connected to the cooling box and the drying box respectively, a fan duct connected to the adjacent outer walls of the cooling box and the drying box through openings, a fan installed inside the fan duct, and strip-shaped filling boxes evenly distributed on the inner wall of the drying box, the inside of the strip-shaped filling boxes filled with drying cotton, and adsorption ports evenly distributed on the outer walls of the strip-shaped filling boxes.

[0008] Preferably, the bottom inner wall of the cooling box is equipped with vertically upward cooling fins that are evenly distributed, and the cooling fins extend through the outer wall of the cooling box to the top of the cooling box.

[0009] Preferably, a positioning frame is fixedly provided on the top outer wall of the cooling box, and two cooling fans are installed on the positioning frame.

[0010] Preferably, the inner wall of the switch cabinet body is fixed with equally spaced electrical mounting plates by screws.

[0011] Preferably, a door is movably connected to one side of the outer wall of the switch cabinet body via a hinge, and a door handle is fixedly provided on one side of the outer wall of the door.

[0012] Preferably, a moisture-proof base is placed at the bottom of the main body of the switch cabinet.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] Air from inside the switchgear is drawn in through circulation holes on the hollow plates on both sides by a fan, enters the cooling box through an air duct, and then flows into the drying box through another air duct. The drying cotton in the strip-shaped filling box inside the drying box absorbs moisture from the air through the adsorption port, thus dehumidifying the switchgear and protecting the internal electrical equipment.

[0015] Because this invention does not exchange fluids with the outside air, it effectively prevents harmful substances such as dust, impurities, and corrosive gases from entering the switch cabinet body. At the same time, it can prevent moisture from entering the switch cabinet body, thus providing good moisture protection. Attached Figure Description

Example 1

[0025] Refer to the instruction manual appendix Figure 1-4 A low-voltage switchgear with a dehumidification structure includes a switchgear body 1. Hollow plates 2 are installed on the inner walls of both sides of the switchgear body 1. The outer walls of the hollow plates 2 have equally spaced circulation holes 3 to allow air to circulate between the switchgear body 1 and the hollow plates 2. A cooling box 4 and a drying box 5 are fixedly installed on the top outer wall of the switchgear body 1. One side of the outer wall of the two hollow plates 2 is connected to an air guide pipe 6 through an opening. The other ends of the two air guide pipes 6 are connected to the cooling box 4 and the drying box 5 respectively, so that air inside the switchgear body 1 can enter the cooling box 4 and the drying box 5 through the air guide pipes 6. An air duct 7 is connected to the adjacent outer wall of the cooling box 4 and the drying box 5 through an opening. A fan 8 is installed inside the air duct 7. When the fan 8 is started, it can promote the air circulation between the cooling box 4, the drying box 5 and the switchgear body 1. Example 2

[0026] Based on Embodiment 1, the inner wall of the drying chamber 5 is equipped with equally spaced strip-shaped filling boxes 12, which are filled with drying cotton 14. The outer wall of the strip-shaped filling boxes 12 has equally spaced adsorption ports 13. When air enters the drying chamber 5, the moisture in the air can be absorbed by the drying cotton 14 through the adsorption ports 13, thereby achieving a dehumidification effect. The bottom inner wall of the cooling chamber 4 is equipped with equally spaced vertically upward cooling fins 9. The cooling fins 9 extend through the outer wall of the cooling chamber 4 to the top of the cooling chamber 4, which can increase the contact area with the air and improve the cooling effect. The top outer wall of the cooling chamber 4 is fixedly equipped with a positioning frame 10, and two cooling fans 11 are installed on the positioning frame 10. When the cooling fans 11 are activated, they can accelerate the airflow, enhance the heat dissipation effect of the cooling fins 9, and thus reduce the air temperature entering the switch cabinet body 1. Example 3

[0027] Based on Embodiment 1, the inner wall of the switch cabinet body 1 is fixed with equally spaced electrical mounting plates 18 by screws for installing various electrical components. One side of the outer wall of the switch cabinet body 1 is movably connected to a cabinet door 15 by a hinge. A door handle 16 is fixed on one side of the outer wall of the cabinet door 15 to facilitate the opening and closing of the switch cabinet body 1 by staff for maintenance and repair of the internal electrical components. A moisture-proof base 17 is placed at the bottom of the switch cabinet body 1 to effectively prevent ground moisture from entering the switch cabinet body 1 and further protect the internal electrical components.

[0028] Working principle of this utility model:

[0029] Refer to the instruction manual appendix Figure 1-4During installation, the hollow plate 2 with equally spaced circulation holes 3 on both inner walls is first installed onto the inner walls of both sides of the switch cabinet body 1. The cooling box 4 and the drying box 5 are then fixedly installed on the top outer wall of the switch cabinet body 1. Next, the air duct 6, whose two ends are connected to the hollow plate 2 and the cooling box 4 and drying box 5 respectively, is connected. Then, a fan duct 7 with a fan 8 is connected to the outer wall of the adjacent side of the cooling box 4 and drying box 5, and the fan 8 is installed inside the fan duct 7. Equally spaced strip-shaped filling boxes 12 are installed on the inner wall of the drying box 5, and drying cotton 14 is filled into the strip-shaped filling boxes 12. Equally spaced cooling fins 9 extending vertically upwards to the top are installed on the bottom inner wall of the cooling box 4. Finally, the cooling box 4 is fixedly positioned on the top outer wall. The frame 10 is assembled, and two cooling fans 11 are installed on the positioning frame 10. Electrical mounting plates 18, which are evenly distributed, are fixedly installed on the inner wall of the switch cabinet body 1 with screws. The cabinet door 15 is movably connected to one side of the outer wall of the switch cabinet body 1 by a hinge, and a door handle 16 is fixedly installed on one side of the outer wall of the cabinet door 15. Finally, the switch cabinet body 1 is placed on the moisture-proof base 17. When in use, the fan 8 and the cooling fan 11 are turned on. The fan 8 causes the air in the switch cabinet body 1 to enter the cooling box 4 and the drying box 5 through the air guide pipe 6. The air is cooled in the cooling box 4 by the cooling fins 9 and the cooling fan 11. After being dehumidified in the drying box 5 by the drying cotton 14, it returns to the switch cabinet body 1 through the air duct 7 and the air guide pipe 6, realizing air circulation, cooling and dehumidification.
