Description

Technical Field

[0001] This utility model relates to a corner busbar trunking, and more particularly to a corner busbar trunking, belonging to the technical field of corner busbar trunking. Background Technology

[0002] Corrosion-resistant busbar trunking is a type of electrical equipment specifically designed to prevent damage to busbar trunking systems from corrosive environments. It features corrosion resistance, high protection level, temperature difference resistance, waterproof performance, insulation performance, large current carrying capacity, strong overload capacity, convenient installation, and low cost. As a result, corrosion-resistant busbar trunking has been widely used in various fields such as industry, construction, and power, especially in situations where high corrosion resistance and safety are required.

[0003] However, existing corner busbar trunking does not have a fast heat dissipation component at the bottom bend of the casing. This causes the cross-sectional area of ​​the conductor to increase due to the bend, which increases the resistance and the amount of heat dissipated. As a result, the heat accumulates at the bend and cannot be dissipated quickly, which greatly reduces the service life of the corner busbar trunking.

[0004] Therefore, it is urgent to improve the corner busbar trunking to solve the above-mentioned problems. Utility Model Content

This device can quickly dissipate heat from the conductors that have increased cross-sectional area, resistance, and heat dissipation due to bending by using a fixed plate in the heat dissipation base plate, several heat dissipation slots, and rapid heat dissipation components.

[0007] Preferably, the rapid heat dissipation assembly includes a mounting frame ring screwed onto the bottom surface of the fixed plate, a fixed bracket disposed on the mounting frame ring, a heat dissipation fan snapped onto the fixed bracket, and a metal mesh mounted on the mounting frame ring.

[0008] Preferably, the connecting support plate consists of two symmetrically installed fixed support plates, each with a first limiting groove on its upper surface, and a first limiting block adapted to the first limiting groove is provided on the lower surface of the fixed top plate.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figures 1-6As shown, the corner busbar trunking provided in this embodiment includes a busbar trunking fixing frame 1, in which several conductive busbars 2 are embedded. The busbar trunking fixing frame 1 includes a fixed top plate 3, a heat dissipation base plate 4 installed below the fixed top plate 3, and a connecting support plate 5 installed between the fixed top plate 3 and the heat dissipation base plate 4. The heat dissipation base plate 4 includes a fixed plate 6, several heat dissipation slots 7 opened on the fixed plate 6, and a fast heat dissipation assembly 8 symmetrically screwed onto the bend of the fixed plate 6. Fixed frame end caps 13 are installed at both ends of the busbar trunking fixing frame 1. The busbar trunking fixing frame 1 is usually made of steel plate or aluminum alloy plate, which facilitates the fixing and protection of the several conductive busbars 2 and the insulating material. The several conductive busbars 2 are the core part of the busbar trunking, usually made of copper or aluminum, and are responsible for transmitting electricity. The fixed top plate 3, the heat dissipation base plate 4, and the connecting support plate 5 can be easily assembled into a busbar. The busbar fixing frame 1 and the heat dissipation base plate 4 facilitate rapid heat dissipation for the several conductive busbars 2 in operation. The connecting support plate 5 facilitates the fixed connection between the fixed top plate 3 and the heat dissipation base plate 4. The fixing plate 6 facilitates the support for the several conductive busbars 2. The heat dissipation slots 7 and the rapid heat dissipation components 8 facilitate rapid heat dissipation for the several conductive busbars 2 operating in the busbar fixing frame 1. The cross-sectional area of ​​the several conductive busbars 2 will increase to a certain extent at the bend, which will lead to an increase in resistance, resulting in more heat generated at the bend. The rapid heat dissipation components 8 can then quickly dissipate heat at the bend, which greatly reduces the service life of the corner busbar. The fixing frame end cap 13 facilitates the sealing of both ends of the busbar fixing frame 1, and also facilitates the connection of several of these devices together, and can also provide a certain degree of protection for the exposed ends of the several conductive busbars 2.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, the rapid heat dissipation assembly 8 includes a mounting frame ring 9 screwed onto the bottom surface of the fixed plate 6, a fixed bracket 10 disposed on the mounting frame ring 9, a heat dissipation fan 11 snapped onto the fixed bracket 10, and a metal mesh cover 12 mounted on the mounting frame ring 9. The mounting frame ring 9 facilitates screwing the rapid heat dissipation assembly 8 onto the heat dissipation base plate 4, the fixed bracket 10 facilitates mounting the heat dissipation fan 11 onto the mounting frame ring 9, the heat dissipation fan 11 facilitates the rapid dissipation of heat at the bend of the busbar trunking fixed frame 1, and the metal mesh cover 12 prevents foreign objects from entering the busbar trunking fixed frame 1.

[0027] Furthermore, such as Figure 1 , Figure 3 as well as Figure 5As shown, the connecting support plate 5 consists of two symmetrically installed fixed support plates 14. The upper surface of each fixed support plate 14 is provided with a first limiting groove 15. The lower surface of the fixed top plate 3 is provided with a first limiting block 16 that is compatible with the first limiting groove 15. The fixed support plate 14 facilitates the fixed top plate 3 and the heat dissipation base plate 4 to be fixedly connected together, while leaving space for installing several conductive bars 2. The first limiting groove 15 and the first limiting block 16 cooperate with each other to facilitate the fixed top plate 3 to be snapped into the connecting support plate 5.

[0028] Furthermore, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the lower end face of the fixed support plate 14 is provided with a second limiting groove 17, and the lower surface of the fixed plate 6 is provided with a second limiting block 18 that is compatible with the second limiting groove 17. The second limiting groove 17 and the second limiting block 18 cooperate with each other to facilitate the heat dissipation base plate 4 to be snapped into the connecting support plate 5.

[0029] Furthermore, such as Figure 1 , Figure 4 as well as Figure 6 As shown, several conductive busbars 2 are inserted and fixed in an insulating fixing frame 19. The insulating fixing frame 19 is installed in the busbar trunking fixing frame 1. The insulating fixing frame 19 facilitates the tight connection of several conductive busbars 2 together, and the tightly connected several conductive busbars 2 are installed in the busbar trunking fixing frame 1.

[0030] Furthermore, such as Figure 1 , Figure 3 , Figure 4 as well as Figure 6 As shown, an embedded fixing block 20 is provided on the outer surface of the insulating fixing frame 19, and a fixing slot 21 that is compatible with the embedded fixing block 20 is provided on the inner side of the fixing support plate 14. The embedded fixing block 20 and the fixing slot 21 cooperate with each other to facilitate the insertion and installation of several conductive bars 2 that are inserted and fixed in the insulating fixing frame 19 into the busbar fixing frame 1.

[0031] Furthermore, such as Figure 1 and Figure 6 As shown, the fixed top plate 3 is fixedly installed on the connecting support plate 5 by bolts, and the heat dissipation bottom plate 4 is fixedly installed on the connecting support plate 5 by bolts, which facilitates tightening the bolts.

[0032] Furthermore, such as Figure 1 and Figure 6 As shown, the fixed frame end caps 13 are all fixedly installed at both ends of the busbar trunking fixed frame 1 by bolts, which facilitates tightening and fixing by bolts.

[0033] like Figures 1-6As shown, the principle of the corner busbar trunking provided in this embodiment is as follows: When using the device, the rapid heat dissipation component 8 should be taken out first, and the rapid heat dissipation component 8 should be screwed and installed at the bend of the heat dissipation base plate 4. Then, the connecting support plate 5 should be taken out and the connecting support plate 5 should be fixed and installed on the heat dissipation base plate 4 with bolts. At this time, it is ensured that the second limiting block 18 is embedded in the second limiting groove 17.

[0034] Then, insert and fix several conductive busbars 2 into the insulating fixing frame 19, and then install the insulating fixing frame 19 with several conductive busbars 2 inserted between the two fixing support plates 14. At this time, it is necessary to ensure that the embedded fixing block 20 is locked in the fixing slot 21.

[0035] Then, the fixed top plate 3 is installed on the connecting support plate 5 and fixed with bolts. At this time, ensure that the first limiting block 16 is embedded in the first limiting groove 15. Then, the fixed frame end cap 13 is fixedly installed on both ends of the busbar trunking fixed frame 1 with bolts.

[0036] When the device is in operation, the heat dissipation slots 7 on the fixed plate 6 will provide basic heat dissipation for the conductive busbars 2 at the non-bending points. At this time, the heat dissipation fan 11 in the rapid heat dissipation component 8 will start to operate, so that the heat generated by the conductive busbars 2 at the bending points will be quickly discharged from the busbar fixing frame 1, thereby preventing the temperature at the bending points from getting too high and thus greatly reducing the service life of the corner busbar.
