[0001] This utility model relates to the field of dense busbar trunking technology, and in particular to a high-protection dense busbar trunking. Background Technology

[0002] High-protection dense busbar trunking is commonly used in power transmission and distribution systems, especially in environments with high electrical safety requirements. As a highly efficient power transmission device, busbar trunking can provide a safe and reliable power transmission solution in both low-voltage and high-voltage power distribution networks. It is mainly composed of busbars, supports, and housings. The protective design of the housing can effectively avoid safety hazards such as electrical accidents and fires.

[0003] The applicant discovered through a search that a Chinese patent discloses "A High-Protection, High-Dissipation Dense Busbar Trunking", with publication (announcement) number "CN218415742U". This patent mainly uses a protective plate on the outside, and the protective plate is slidably connected to the busbar trunking body and fixed by fasteners, which facilitates installation and disassembly. However, the protective plate in this device is a whole and cannot be flexibly adjusted according to different needs or installation environment. When maintenance or inspection is required, the entire protective plate may need to be disassembled or moved, which is quite troublesome. Therefore, we propose a high-protection dense busbar trunking. Utility Model Content

[0004] The purpose of this utility model is to provide a high-protection dense busbar trunking to solve the problem mentioned in the background art that the protective plate is a whole and cannot be flexibly adjusted according to different needs or installation environment. When maintenance or inspection is required, the whole plate protection may need to be disassembled or moved, which is more troublesome to operate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-protection dense busbar trunking, comprising a busbar trunking structure, on which a protective structure and an installation structure are installed. The busbar trunking structure includes a busbar trunking, and the protective structure includes a sliding groove, a limiting block, a first fastening bolt, a first protective plate, and a second fastening bolt. The first fastening bolt is installed on the busbar trunking via the limiting block. The first protective plate is slidably installed on the busbar trunking via a sliding rail and a sliding groove. The second fastening bolt is threaded onto the side wall of the first protective plate. A second protective plate is slidably installed inside the first protective plate. A threaded hole is formed at one end of the first protective plate.

[0006] As a preferred embodiment, the busbar structure includes lugs, fixing rods, and fixing plates. The lugs are fixedly installed at both ends of the busbar, the fixing rods are fixedly installed at the top of the lugs, and the fixing plates are fixedly installed at the top of the fixing rods.

[0007] As a preferred embodiment, the chute is formed on the side wall of the busbar trough, the limiting block is fixedly installed at the top position on one side of the busbar trough, and the first fastening bolt is threaded onto the limiting block.

[0008] As a preferred embodiment, the slide rail is fixedly installed on the inner wall of the first protective plate, and the first fastening bolt limits and fixes the first protective plate through the threaded hole.

[0009] As a preferred embodiment, the installation structure includes a support plate, a slot, an insulating partition, a support member, a first vent hole, a rectangular box, a cover plate, and a second vent hole. The support plate is fixedly installed inside the busbar trough. The slots are respectively provided on the bottom wall of the busbar trough and the support plate. The insulating partition is installed on the busbar trough and the support plate through the slots. The support member is fixedly installed on the busbar trough and the support plate. The first vent hole is provided on the support member.

[0010] As a preferred embodiment, the rectangular box is fixedly installed on both sides of the busbar trunking, the rectangular box contains a desiccant, the rectangular box is provided with a second vent hole, and a cover plate can be detachably installed on the other side of the rectangular box.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. In the designed protective structure, the first fastening bolt extends into the threaded hole to fix the first protective plate, ensuring that the protective plate will not loosen or shift, thus guaranteeing the stability of the busbar trunking protective structure. The second protective plate slides within the first protective plate, and the second fastening bolt is rotated to limit the position of the second protective plate. The adjustment of the second protective plate is more flexible, and it can be precisely positioned according to actual needs to meet different environments or installation requirements. Since the second protective plate can slide and is limited by the second fastening bolt, maintenance personnel can easily adjust the state of the protective plate or replace the protective plate as needed without disassembling the complex structure.

[0013] 2. The installation structure reduces contact between the busbar and the busbar trough through the support components, avoiding wear or damage caused by friction and extending the service life of the busbar trough. The first vent on the support component effectively dissipates heat from the busbar, preventing equipment failure or efficiency reduction due to excessive temperature. It also maintains air circulation within the busbar trough, reducing the long-term impact of high temperature on the busbar. The insulating partition separates the busbars, effectively isolating the electrical connections between different busbars, thereby reducing the probability of short circuits or electrical faults. The rectangular box contains a desiccant to absorb moisture in the busbar trough. Attached Figure Description

[0025] The protective structure 2 includes a slide 21, a limiting block 22, a first fastening bolt 23, a first protective plate 24, and a second fastening bolt 26. The slide 21 is formed on the side wall of the busbar trough 11. The limiting block 22 is fixedly installed at the top of one side of the busbar trough 11. The first fastening bolt 23 is threaded onto the limiting block 22. The first protective plate 24 is positioned above the busbar trough 11. The limiting block 22 is used to limit the first protective plate 24 and prevent it from sliding out of the busbar trough 11. A slide rail 25 is fixedly installed on the inner wall of the first protective plate 24, and the slide rail 25 extends into the slide rail. In the groove 21, the first protective plate 24 is slidably connected to the slide rail 25 and the slide groove 21, so that the first protective plate 24 slides on the busbar groove 11. The second fastening bolt 26 is threaded on the side wall of the first protective plate 24. The second protective plate 27 is slidably installed inside the first protective plate 24. The second fastening bolt 26 limits the second protective plate 27. A threaded hole 28 is opened at one end of the first protective plate 24. The first fastening bolt 23 limits and fixes the first protective plate 24 through the threaded hole 28. This structure can ensure the stability and safety of the first protective plate 24.

[0026] Specifically, in the protective structure 2, the first fastening bolt 23 extends into the threaded hole 28, thereby fixing the first protective plate 24 and ensuring that the first protective plate 24 will not loosen or shift, thus ensuring the stability of the busbar trough 11. The second protective plate 27 slides in the first protective plate 24, and the second fastening bolt 26 is rotated to limit the position of the second protective plate 27. The adjustment of the second protective plate 27 is more flexible and can be precisely positioned according to actual needs to meet different environments or installation requirements. Since the second protective plate 27 can slide and is limited by the second fastening bolt 26, maintenance personnel can easily adjust the state of the second protective plate 27 without disassembling the complex structure.

[0027] Example 2:

[0028] Please see the appendix Figure 6 and attached Figure 7The installation structure 3 includes a support plate 31, a slot 32, an insulating partition 33, a support member 34, a first vent 35, a rectangular box 36, a cover plate 37, and a second vent 38. The support plate 31 is fixedly installed inside the busbar trough 11, dividing the busbar trough 11 into upper and lower parts. The slot 32 is respectively set on the bottom wall of the busbar trough 11 and the support plate 31. The insulating partition 33 is installed on the busbar trough 11 and the support plate 31 through the slot 32. The support member 34 is fixedly installed on the busbar trough 11. On the support plate 31, a first vent 35 is provided on the support member 34. A rectangular box 36 is fixedly installed on both sides of the busbar trough 11. The rectangular box 36 contains a desiccant to absorb moisture. The rectangular box 36 is provided with a second vent 38 facing the inside of the busbar trough 11. A cover plate 37 is detachably installed on the other side of the rectangular box 36 to facilitate maintenance and replacement of the desiccant, effectively preventing moisture accumulation in the busbar trough 11 and providing a convenient function for inspection and replacement of the desiccant.

[0029] Specifically, in the installation structure 3, the support member 34 reduces the contact between the busbar and the busbar trunking 11, avoiding wear or damage caused by friction and extending the service life of the busbar trunking 11. The first vent hole 35 on the support member 34 can effectively dissipate heat from the busbar, effectively helping to dissipate heat from the busbar and preventing equipment failure or efficiency reduction due to excessive temperature. It also maintains air circulation in the busbar trunking 11, reducing the long-term impact of high temperature on the busbar. The insulating partition 33 separates the busbars, effectively isolating the electrical connection between different busbars, thereby reducing the probability of short circuits or electrical faults. The rectangular box 36 contains a desiccant, which absorbs moisture in the busbar trunking 11.

[0030] Working principle of this utility model: This utility model is a high-protection, high-density busbar trunking. The busbar trunking 11 is provided with stable installation and support through the combination of lugs 12, fixing rods 13, and fixing plates 14. The first protective plate 24 is slidably installed on the busbar trunking 11 through slide rails 25 and slide grooves 21. The first protective plate 24 is brought into contact with the limiting block 22. The first fastening bolt 23 is rotated, and the first fastening bolt 23 extends into the threaded hole 28, fixing the first protective plate 24 through the threaded hole 28. The second protective plate 27 slides in the first protective plate 24. The second fastening bolt 26 is rotated to fix the second protective plate 27. Limiting is achieved by using the first protective plate 24 and the second protective plate 27 to protect the busbar trough 11. The busbar is arranged on the support member 34, which reduces the contact between the busbar and the busbar trough 11. The first vent hole 35 on the support member 34 can effectively dissipate heat from the busbar. The insulating partition 33 separates the busbar, thus providing additional isolation protection. The rectangular box 36 contains desiccant, which absorbs moisture in the busbar trough 11, keeping the busbar trough 11 dry. The cover plate 37 can be opened to facilitate inspection and replacement of the desiccant, ensuring the long-term stable operation of the equipment.
