Description

Technical Field

[0001] This utility model relates to the field of power facility technology, specifically a terminal block system suitable for high power. Background Technology

[0002] High-power terminal blocks are core power distribution devices used in high-load scenarios, widely applied in industrial production lines, data centers, power base stations, large venues, and medical facilities. Their design must meet core requirements such as high current carrying capacity, efficient heat dissipation, safety protection, and long-term stability. Existing conventional conductor materials generally have high resistivity, resulting in significant temperature rise under high current, which easily accelerates oxidation and aging, leading to poor contact or even melting. Their current carrying capacity per unit cross-sectional area is insufficient, necessitating increased volume or parallel connection. However, simply increasing resistance is space-consuming and costly, and enclosed devices lack sufficient heat dissipation capacity, relying on natural convection or simple ventilation holes, which cannot cope with prolonged high loads. Localized hot spots can easily cause carbonization of the insulation material, and excessively high temperatures can lead to system derating. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a terminal block system suitable for high power. By reducing the length of the copper busbar, differentiating the distribution density of the heat dissipation fins, and combining the cooling fan with the ventilation structure, it solves the problem of excessive temperature rise caused by uneven heating of copper busbars in different phases under high current.

[0004] To achieve the above objectives, a suitable high-power terminal block system is designed, including a copper busbar branch box. Inside the copper busbar branch box, a mounting plate is vertically connected. On one side of the mounting plate, a first copper busbar, a second copper busbar, a third copper busbar, a fourth copper busbar, and a fifth copper busbar are installed side by side in sequence. A cooling fan is provided on the other side of the mounting plate. The lengths of the first copper busbar, the second copper busbar, the third copper busbar, the fourth copper busbar, and the fifth copper busbar decrease sequentially. The first copper busbar, the second copper busbar, the third copper busbar, the fourth copper busbar, and the fifth copper busbar are provided with copper busbar sleeves of different colors, and each of them has heat dissipation fins on its inner side.

[0005] The copper busbar branch box has an openable door on one side with a handle, a ventilation and protective net on the other side, a side ventilation hole on the side of the copper busbar branch box, and a wiring hole at the bottom of the side of the copper busbar branch box.

[0006] The first copper busbar is the N-phase busbar, the second copper busbar is the A-phase busbar, the third copper busbar is the B-phase busbar, the fourth copper busbar is the C-phase busbar, and the fifth copper busbar is the PE busbar.

[0007] The heat dissipation fins form a 10° angle with the horizontal planes of the first, second, third, fourth, and fifth copper busbars, and the distribution density of the heat dissipation fins on the first, second, third, fourth, and fifth copper busbars decreases sequentially.

[0008] The mounting plate has a fixing stake on one side, and an insulating sleeve is fitted on the fixing stake for installing the first copper busbar, the second copper busbar, the third copper busbar, and the fourth copper busbar.

[0009] Compared with the prior art, this utility model customizes the copper busbar length and heat dissipation fin distribution according to the phase current characteristics to dissipate heat and protect against short circuit accidents and wiring risks. It has strong heat dissipation performance and safety protection and can meet the needs of high-power power consumption scenarios with multiple users. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 3 As shown, the copper busbar branch box 1 is vertically connected to the mounting plate 4. The vertical installation of the mounting plate 4 saves space, and its modular design facilitates future maintenance or expansion. On one side of the mounting plate 4, the first copper busbar 9, the second copper busbar 10, the third copper busbar 11, the fourth copper busbar 12, and the fifth copper busbar 13 are installed side-by-side. The other side of the mounting plate 4 is equipped with a cooling fan 6. The lengths of the first copper busbar 9, the second copper busbar 10, the third copper busbar 11, the fourth copper busbar 12, and the fifth copper busbar 13 decrease sequentially. This different length arrangement effectively prevents short circuits. The first copper busbar 9, the second copper busbar 10, the third copper busbar 11, the fourth copper busbar 12, and the fifth copper busbar 13 are equipped with copper busbar sleeves 14 of different colors, each with heat dissipation fins 15 on its inner side. The copper busbar sleeves 14 are fixed to the surface of the copper busbar by clips. Figure 4 , 5As shown in the diagram, the two copper busbars at the two ends are the most representative. The other copper busbars differ only in size and the arrangement of heat dissipation fins 15, so they are not listed separately. The first copper busbar 9 is the N-phase busbar, the second copper busbar 10 is the A-phase busbar, the third copper busbar 11 is the B-phase busbar, the fourth copper busbar 12 is the C-phase busbar, and the fifth copper busbar 13 is the PE busbar. The copper busbar sheath 14 of the N-phase busbar is blue, the copper busbar sheath 14 of the A-phase busbar is yellow, the copper busbar sheath 14 of the B-phase busbar is green, and the copper busbar sheath 14 of the C-phase busbar is red. The different colored copper busbar sheaths 14 clearly distinguish the phases and reduce the risk of wiring errors.

[0018] like Figure 1 , 2 As shown, the copper busbar branch box 1 has an operable door 2 on one side with a handle 3, and a ventilation and protective mesh 7 on the other side. The side of the copper busbar branch box 1 also has side ventilation holes 8. The ventilation and protective mesh 7 and the side ventilation holes 8, combined with the cooling fan 6, enhance natural convection and achieve heat dissipation. A wiring hole 5 is located at the lower side of the copper busbar branch box 1.

[0019] The heat dissipation fins 15 form a 10° angle with the horizontal planes of the first copper busbar 9, the second copper busbar 10, the third copper busbar 11, the fourth copper busbar 12, and the fifth copper busbar 13. The distribution density of the heat dissipation fins 15 on the first copper busbar 9, the second copper busbar 10, the third copper busbar 11, the fourth copper busbar 12, and the fifth copper busbar 13 decreases sequentially. The specific distribution density can be reasonably allocated according to the heat generation of different copper busbars.

[0020] One side of the mounting plate 4 is provided with a fixing post 16 for installing the first copper busbar 9, the second copper busbar 10, the third copper busbar 11, and the fourth copper busbar 12. An insulating sleeve 17 is fitted on the fixing post 16. The insulating sleeve 17 and the fixing post 16 are designed to enhance electrical isolation and prevent short circuits.

[0021] During installation, the mounting plate 4 is vertically fixed in the center of the copper busbar branch box 1, ensuring it is perpendicular to the bottom and side walls of the box. Long bolts are inserted into the four corners of the mounting plate 4 and the back of the copper busbar branch box 1 for fixation. The first copper busbar 9, the second copper busbar 10, the third copper busbar 11, the fourth copper busbar 12, and the fifth copper busbar 13 are installed sequentially from left to right, decreasing in length. Each copper busbar is fixed to the mounting plate 4 using fixing posts 16. An insulating sleeve 17 is fitted onto the surface of the fixing posts 16 to ensure electrical isolation between the copper busbars and the mounting plate 4. A heat dissipation device is welded to the inner side of each copper busbar. The fins 15 are inclined at a 10° angle to the copper drain plane, forming a flow channel. Since the first copper busbar 9, i.e. the N-phase busbar, generates the most heat, it is equipped with more heat dissipation fins 15. A cooling fan 6 is installed on the other side of the mounting plate. Cool air enters through the side ventilation hole 8, is guided by the heat dissipation fins 15, and is forced out by the cooling fan 6, forming a circulating air duct. Through structural innovation and systematic design, this utility model achieves efficient heat dissipation, safety protection, and compact layout of high-power terminal blocks, significantly improving the reliability and economy of the power distribution system.
