Description

Technical Field

[0001] This utility model relates to the field of power distribution technology, and in particular to a modular, openable, waterproof and heat-dissipating top cover for a low-voltage switchgear. Background Technology

[0002] With the rapid development of electrical technology, electrical equipment plays an increasingly important role in people's lives. However, continuous operation of electrical equipment can lead to overheating, affecting the safety of the equipment and current system. Therefore, an effective heat dissipation system is needed to ensure the normal operation of electrical equipment. Meanwhile, low-voltage switchgear is used unattended for extended periods, requiring protection of the internal components from moisture. The top cover cannot completely conceal the top of the cabinet, failing to prevent condensation from entering the cabinet from the distribution room, nor effectively preventing dust from entering through the top cover. Existing waterproof heat dissipation top covers cannot be opened, resulting in insufficient ventilation and hindering the installation of main busbars.

[0003] Therefore, it is necessary to develop a waterproof and heat-dissipating top cover for low-voltage cabinets that can be opened to overcome the above problems. Utility Model Content

[0005] Technical Solution: This utility model discloses a modular, openable, waterproof, and heat-dissipating top cover for a low-voltage switchgear. The top cover comprises several front and rear top plates. The front top plate is connected to a top cover with heat dissipation holes via a front and rear welded component. Several lifting rings are provided on both the front and rear top plates. The rear top plate may or may not have lifting rings on its side. The top cover is fixed with several self-tapping screws. A welding wire mesh, a sealing strip, and a top cover lock are provided on the inner side of the top cover. The top cover is flipped via a top cover hinge.

[0006] The number of the front and rear roof panels is 3 or 4.

[0007] The front and rear top panels are located on three or four cabinets.

[0008] The front roof panel includes front roof panel one, front roof panel two, and front roof panel three; the rear roof panel includes rear roof panel one, rear roof panel two, and rear roof panel three.

[0009] The front and rear top panels are equipped with waterproof pads, and the rear top panel is equipped with waterproof pads.

[0010] The self-tapping screw is equipped with a second waterproof gasket.

[0011] The cabinet is a low-voltage cabinet, and the cabinets are connected by a welded structure.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention provides an effective natural ventilation and heat dissipation method, and increases the area of ​​the top ventilation holes; ensures that the internal components of the power equipment are not damaged by moisture, strengthens the waterproofing between cabinets, and meets the needs of different numbers of cabinets; effectively prevents dust from entering from the top cover; the two-section split structure of the top cover with hinged door locks makes it easy to open and facilitates the installation of the main busbar when assembling cabinets.

[0013] This utility model can not only meet the requirements of preventing vertical dripping water, but also ensure natural ventilation of the top cover, and meet the protection requirements of the sides and between the cabinets. With the use of sealing strips, the protection level of the cabinet can reach IP41, which can effectively ensure the safe operation of the components inside the cabinet. Adjusting the number of top covers can also meet the needs of different numbers of cabinets. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model relates to a modular, openable, waterproof, and heat-dissipating top cover for a low-voltage switchgear, comprising several front and rear top plates. The front top plate is connected to a top cover 6 with heat dissipation holes via a front part 4 and a rear part 5 of a top cover welding component. Several lifting rings 7 are provided on the front and rear top plates, while the rear top plate may or may not have lifting rings 7 on its side. The top cover 6 is fixed by several self-tapping screws 9. The inner side of the top cover 6 is provided with a welding wire mesh 11, a sealing strip 12, and a top cover lock 14. The top cover 6 is flipped over by a top cover hinge 18.

[0025] This utility model has 3 or 4 front and rear top panels. The front and rear top panels are located on 3 or 4 cabinets. The front top panels include front top panel one 15, front top panel two 16, and front top panel three 17; the rear top panels include rear top panel one 1, rear top panel two 2, and rear top panel three 3. Waterproof gasket one 8 is provided at the lifting ring 7 on the front and rear top panels, and waterproof gasket three 13 is provided at the lifting ring 7 on the side of the rear top panel. Waterproof gasket two 10 is provided at the self-tapping screw 9. The cabinets are low-voltage cabinets, and the cabinets are connected by a welded structure.

[0026] This invention achieves the requirements of natural heat dissipation and ventilation of the cabinet while preventing vertical water dripping intrusion. Welded wire mesh is used to protect the ventilation holes, preventing solid objects larger than φ1mm from entering the top cover. Waterproof gaskets one at the lifting rings and two at the self-tapping screws on the top cover prevent direct vertical water dripping intrusion. The 45° top cover, with a width far exceeding that of the ventilation holes, effectively prevents water droplets from rebounding and entering through the ventilation holes. The widening of the left side of top cover one and the right side of top cover three, along with the downward U-shaped bends on the right sides of top cover one and two, increases the water droplet collection area of ​​the top plate, meeting the protection requirements for the sides and between cabinet units. This waterproof top cover not only meets the requirements of preventing vertical water dripping and ensuring natural ventilation, but also meets the protection requirements for the sides and between cabinet units. Combined with the use of sealing strips, the cabinet's protection level reaches IP41, effectively ensuring the safe operation of the components inside the cabinet. Increasing the number of top covers two can meet the needs of different numbers of cabinet units.

[0027] The second rear top panel can be equipped with multiple panels to meet the needs of different numbers of cabinets. The top cover is bent at 45° around its perimeter, and its dimensions far exceed the width of the ventilation holes. The ventilation holes of top panels one, two, and three are protected with welded wire mesh. Waterproof gaskets one and two prevent direct vertical intrusion of dripping water. The front and rear welded parts of top panels one, two, three, and the top cover are welded together to ensure a gapless connection. The left side of top cover one is widened, and the right side of top cover three is widened. The downward U-shaped bend on the right side of top covers one and two increases the water droplet collection area of ​​the top panels, meeting the protection requirements of the sides of the cabinets and between cabinets.
