Description

Technical Field

[0001] This utility model relates to the field of horizontal busbar structures, specifically a horizontal busbar with a semi-covered film. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all industries has increased rapidly, especially with the rise of numerous high-rise buildings and large factory workshops. Traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems, and the parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Plug-in busbar trunking, as a new type of power distribution conductor, has emerged. Compared with traditional cables, it fully demonstrates its superiority in high-current transmission. Furthermore, due to the adoption of new technologies and processes, it significantly reduces the contact resistance and temperature rise at the connection points of both ends of the busbar trunking and at the branch line insertion points. High-quality insulation materials are also used in the busbar trunking, thereby improving its safety and reliability and making the entire system more complete.

[0003] Chinese patent CN201051637Y discloses an aluminum alloy-cased busbar trunking. It features two aluminum alloy side plates on either side of parallel conductors covered with an insulating layer. Two aluminum alloy cover plates are assembled on these side plates without screws using pressure plates, pressure blocks, and retaining springs. The side plates and cover plates constitute the aluminum alloy casing. This invention improves the insulation reliability, current carrying capacity, casing protection level, and corrosion resistance of busbar trunking products, extending their service life. The screwless assembly technology between the busbar trunking casing cover plates and side plates enhances the protection level. The dovetail grooves and serrated heat sinks on the side plates increase the current carrying capacity of the busbar trunking. The insulating coating formed by the hot-coating process of fast-curing epoxy powder on the conductors improves the heat resistance and dielectric strength, and is non-flammable, halogen-free, and non-toxic, meeting environmental protection requirements.

[0004] In summary, the existing busbar system has many drawbacks, which are summarized as follows:

[0005] ① Existing busbars occupy a large amount of space, and the application scenarios that can be expanded based on busbars are limited;

[0006] ② The existing busbar insulation strips or air-type heat dissipation are poor, with a large temperature difference between the inside and outside, requiring a larger copper busbar interface. Moreover, the overall product has not been realized, and prefabrication and quick on-site installation cannot be achieved.

[0007] ③ Polyester insulation film is also used in dense busbars. Polyester insulation film is characterized by good insulation performance, film thickness within 0.2mm, and good thermal conductivity. However, if the film comes into direct contact with the aluminum alloy shell, it is easy to be scratched at the cross-section of the shell. Utility Model Content

[0008] In view of the shortcomings of the prior art, this utility model provides a horizontal busbar with a semi-covered film to solve the above problems.

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0010] A horizontal busbar with a semi-covered film includes a busbar trunking body, copper busbars, a film, and a fixing device. The copper busbars are sequentially and spaced apart within the busbar trunking body. The film is integrally connected between the busbar trunking body and the copper busbars. The fixing device secures the copper busbars to the busbar trunking body. The busbar trunking body has a connecting end and a fixing end. The fixing end extends through both sides of the busbar trunking body. The connecting end has several copper busbar fixing slots for mounting the copper busbars and the film. Chamfers are provided at the turning points of the copper busbar fixing slots. The overall design is horizontal with side-mounted cabling. By exchanging horizontal space for vertical space, the busbar achieves rapid heat dissipation through the combination of membrane, copper busbar, and busbar trunking. In addition, the fixing device on the busbar trunking simplifies the overall structure and enables rapid on-site installation. Chamfers are provided at the turning points of the copper busbar fixing groove, so there are no sharp edges in contact with the membrane, eliminating the risk of being scratched. This not only takes advantage of the side connection of the horizontal busbar, but also uses the pressure fixing blocks and end cap fixing parts of the fixing device to fix the middle and sides of the copper busbar, solving the disadvantage of difficult thermoforming of horizontal busbars.

[0011] Preferably, the fixing device includes a pressure fixing block and an end cap fixing component. The pressure fixing block is connected to the fixing end and is used to fix the middle part of the copper busbar. The end cap fixing component is connected to both sides of the fixing end and is used to fix both ends of the copper busbar.

[0012] Preferably, the end cap fixing component includes an end cap body and an end cap pressure plate, wherein the end cap body and the end cap pressure plate are engaged.

[0013] Preferably, the end cap body is provided with an end cap fixing groove, an end cap snap-fit ​​groove, and an end cap limiting groove. The end cap fixing groove is connected to the fixing end by bolts. The shape of the end cap limiting groove is adapted to the shape of the copper busbar fixing groove for placing the copper busbar.

[0014] Preferably, the end cap pressure plate includes a pressure plate fixing groove, a pressure plate snap-fit ​​groove, and a pressure plate limiting groove. The pressure plate fixing groove is connected to the fixed end by bolts. The shape of the pressure plate limiting groove is adapted to the shape of the copper busbar fixing groove and is used to limit the copper busbar by combining with the end cap limiting groove.

[0015] Preferably, the shape of the pressure plate locking groove and the end cap locking groove are correspondingly engaged.

[0016] Preferably, the busbar trunking body has a heat dissipation groove on the other side opposite to the copper busbar fixing groove.

[0017] Preferably, a protective plate is connected above the fixed end of the busbar trunking body, and the protective plate is distributed at intervals between the pressure fixing blocks.

[0018] Preferably, the upper end of the copper busbar is provided with an insulating cap.

[0019] Preferably, the film is a polyester insulating film.

[0020] Compared to existing technologies, this utility model discloses a horizontal busbar with a semi-covered film, comprising a busbar trunking body, copper busbars, a film, and a fixing device, which work together to fulfill their functions.

[0021] ① The overall layout adopts a horizontal orientation with side wiring, using horizontal space to gain vertical space;

[0022] ② The busbar can be rapidly cooled by combining the thin film, copper busbar, and busbar trunking body. In addition, the fixing device on the busbar trunking body simplifies the overall structure and enables rapid on-site installation.

[0023] ③ Chamfers are provided at all turns of the copper busbar fixing groove, so there are no sharp edges in the places that come into contact with the film, and there is no risk of being scratched;

[0024] ④ It not only takes advantage of the side connection of the horizontal busbar, but also completes the fixation of the middle and both sides of the copper busbar through the pressure fixing block and end cover fixing of the fixing device, thus solving the disadvantage of the difficulty of hot forming of the horizontal busbar.
