[0002] Busbar ducts are enclosed metal devices made of copper and aluminum busbars. They are used to distribute high power to various components in a distributed system. Busbar ducts are often combined together. The simultaneous use of multiple busbars generates significant heat, which, if not dissipated promptly, can affect the busbar's normal operation. Therefore, it is necessary to propose a lightweight modular busbar duct to address this issue. Utility Model Content

[0003] The purpose of the utility model is to provide a lightweight modular bus duct to solve the problem that when multiple bus ducts are used at the same time, more heat will be generated. If the heat cannot be discharged in time, the normal use of the bus duct will be affected.

[0006] Preferably, an electromagnet is provided on one side of the power connection plate and the power supply connection plate, and the two electromagnets are magnetically attracted to each other.

[0007] Preferably, a transparent observation window is provided on one of the plastic connecting tubes, and the transparent observation window is arranged opposite to the micro resistance tester.

[0008] Preferably, U-shaped protective covers are slidably provided on both ends of the plastic bus duct housing.

[0009] The technical effects and advantages of this utility model are:

[0010] 1. During operation, insert the square inner tube at one end of the plastic connecting tube on one bus duct into the square inner groove at the other end of the other plastic connecting tube, and insert the connecting bolt into the corresponding connecting groove. Turn the connecting bolt to fix the two bus ducts together, with high connection stability.

[0011] 2. The plastic connecting pipes of the two bus ducts form a channel.

At this time, if the bus duct is damaged, the internal conductive sheet breaks and separates. At this time, the micro resistance tester detects that the bus duct has no resistance, indicating that the bus duct is damaged. The damaged bus duct can be automatically detected, thereby saving maintenance time and improving maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides Figure 1-Figure 3 A lightweight modular bus duct shown includes a plastic bus duct shell 1, a conductive sheet is arranged inside the plastic bus duct shell 1, and busbar connectors 2 electrically connected to the conductive sheet are arranged at both ends of the plastic bus duct shell 1. The plastic bus duct shell 1 is made of plastic, which can reduce the weight of the bus duct. This type of setting belongs to the existing technology and is therefore not limited.

[0020] In order to solve the problem that more heat will be generated when multiple bus ducts are used at the same time, and if the heat cannot be discharged in time, it will affect the normal use of the bus duct, the utility model is fixed with plastic connecting pipes 3 on both sides of the plastic bus duct shell 1, and heat conducting plates 4 are provided at both ends of the plastic bus duct shell 1. One end of the heat conducting plate 4 is arranged inside the plastic connecting pipe 3, and one end of the plastic connecting pipe 3 is provided with a square inner pipe 5. The other end of the plastic connecting pipe 3 is provided with a square inner groove 6. The square inner pipe 5 is arranged in coordination with the square inner groove 6. One side of the square inner pipe 5 at one end of the plastic connecting pipe 3 is threadedly connected to a connecting bolt 7, and one side of the square inner groove 6 at the other end of the plastic connecting pipe 3 is provided with a connecting bolt The card slot 8 and the connecting bolt 7 are arranged in conjunction with the connecting card slot 8. A heat dissipation fan 9 is provided inside the two plastic connecting tubes 3. When working, the square inner tube 5 at one end of the plastic connecting tube 3 on one of the bus ducts is inserted into the square inner groove 6 at the other end of the other plastic connecting tube 3. At the same time, the connecting bolt 7 is inserted into the corresponding connecting card slot 8. The two bus ducts can be fixedly connected together by rotating the connecting bolt 7. The connection stability is high. At the same time, the plastic connecting tubes 3 of the two bus ducts form a channel. The heat conducting plate 4 on the bus duct can guide the heat inside the bus duct into the channel, which can quickly dissipate heat. At this time, starting the heat dissipation fan 9 can quickly export the heat inside the channel, and the heat dissipation effect is good.

[0021] Furthermore, the utility model is provided with an electrical connection plate 10 on the top of the heat dissipation fan 9, and a power supply connection plate 11 is electrically connected to the conductive sheet, and the power supply connection plate 11 is located inside one of the plastic connecting tubes 3, and the electrical connection plate 10 and the power supply connection plate 11 are arranged in coordination, and an electromagnet 12 is provided on one side of the electrical connection plate 10 and the power supply connection plate 11, and the two electromagnets 12 are magnetically attracted to each other. When the bus duct is working normally, the electromagnet 12 connected to the conductive sheet is in an energized state, so the two electromagnets 12 are magnetically attracted to each other, so that the power supply connection plate 11 is electrically connected to the electrical connection plate 10. At this time, the bus duct can supply power to the heat dissipation fan 9, so the heat dissipation fan 9 can work normally to dissipate heat for the bus duct.

[0022] It should be noted that a micro transformer can be installed between the power connection plate 10 and the heat dissipation fan 9 to ensure that the voltage of the bus duct can drive the heat dissipation fan 9 to operate normally after the voltage is reduced. This technology belongs to the existing technology and is not limited thereto.

[0023] Furthermore, in order to solve the problem that when multiple bus ducts work together, it takes a lot of time to find the damaged bus ducts among the multiple bus ducts, resulting in low maintenance efficiency, the utility model is provided with a micro resistance tester 13 inside one of the plastic connecting tubes 3, and the bottom of the micro resistance tester 13 is fixedly connected to one end of a tension spring 14, and the other end of the tension spring 14 is fixedly connected to the power supply connection plate 11. The power supply connection plate 11 and the micro resistance tester 13 are arranged in cooperation. During operation, when one of the bus ducts is damaged, the electromagnet 12 inside the plastic connecting tube 3 is powered off, and under the tension of the tension spring 14, the power supply connection plate 11 moves up and contacts the micro resistance tester 13. At this time, if the bus duct is damaged, the internal conductive sheet breaks and separates. At this time, the micro resistance tester 13 detects that the bus duct has no resistance, indicating that the bus duct is damaged. It can automatically detect the damaged bus duct, thereby saving maintenance time and improving maintenance efficiency.

[0024] A transparent observation window 16 is provided on one of the plastic connecting tubes 3 , and the transparent observation window 16 is arranged opposite to the micro resistance tester 13 . The setting of the transparent observation window 16 facilitates observation of the micro resistance tester 13 .
