Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct with an anti-deformation reinforcement structure. Background Art

[0002] In modern power transmission systems, busbar ducts, as a crucial conductive device, are widely used in high-rise buildings, large factories, data centers, and other locations. Busbar ducts' primary function is to efficiently and safely transmit electrical energy, and their performance directly impacts the stability and safety of the entire power system.

[0003] However, traditional busbar trunking is susceptible to deformation over long-term use due to electrodynamic, thermal, and mechanical forces. This not only affects its electrical conductivity but can also pose safety risks. Current busbar trunking products on the market primarily enhance their deformation resistance by increasing the shell thickness or using high-strength materials. While these methods enhance the strength of the busbar trunking to a certain extent, they also have some drawbacks. On the one hand, increasing the shell thickness increases the busbar trunking's weight, making installation and maintenance inconvenient; on the other hand, using high-strength materials increases production costs, hindering product promotion and application.

[0012] Through the above technical solution, when the two reinforced shells are tightened, by setting a number of dividing strips to abut against the outer surface of the copper busbar, the four copper busbars can be kept in close contact with each other, thereby improving the overall structure of the bus duct and making it occupy less space. At the same time, the several dividing strips can also increase the structural strength of the entire reinforced shell.

[0015] Preferably, flame-retardant silicone strips are filled between the separation strips.

[0016] Through the above technical solution, the insulation can be further enhanced by arranging flame-retardant silicone strips to fit the outer surface of the copper busbar.

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.

[0028] See also Figure 1-Figure 4 A bus duct with an anti-deformation reinforcement structure includes a copper busbar 1, a reinforcement shell 2 is provided on the outer surface of the copper busbar 1, a cover plate 3 is connected to both sides of the reinforcement shell 2, a rectangular groove 4 is formed on the outer surface of the cover plate 3, a fastening block 5 is slidably connected in the rectangular groove 4, an L-shaped hook plate 6 is fixedly connected to one side of the fastening block 5, and the inner thread of the fastening block 5 is connected to a double-threaded rod 7;

[0029] The reinforced housing 2 includes a side panel 21 , a partition bar 22 , heat dissipation fins 23 and a clamping bar 24 . The inner side of the side panel 21 is fixedly connected to the partition bar 22 , and the outer side of the side panel 21 is fixedly connected to the heat dissipation fins 23 and the clamping bar 24 .

[0030] Specifically, four groups of copper bars 1 are provided, each group of copper bars 1 being closely attached to one another and coated with an insulating medium. Advantageously, these four groups of copper bars 1 provide the bus duct with excellent current transmission capabilities. The close contact between the copper bars 1 saves space, making them suitable for space-constrained applications. Furthermore, the close contact between the copper bars improves the rigidity and stability of the overall structure, and the insulating medium coating on their outer surfaces prevents mutual conduction.

[0031] Specifically, a plurality of dividing bars 22 are fixedly connected at equal intervals to the inner side of the side plate 21, and the end of the dividing bar 22 away from the side plate 21 contacts the outer surface of the copper busbar 1. The advantage is that when the two reinforced shells 2 are fastened, by providing a plurality of dividing bars 22 to contact the outer surface of the copper busbar 1, the four copper busbars 1 can be kept in close contact with each other, thereby improving the overall structure of the busbar duct and making it occupy less space. At the same time, the plurality of dividing bars 22 can also increase the structural strength of the entire reinforced shell 2. After the various components of the busbar duct are assembled, it has good structural strength and will not cause deformation or bending problems.

[0032] Specifically, three equally spaced snap-in strips 24 are fixedly connected to the outside of the side panel 21. The L-shaped hook plate 6 is hooked with the snap-in strips 24. Three sets of through holes are provided on both sides of the cover plate 3, and the double-threaded rods 7 are rotatably connected to the through holes.

In this way, the two fastening blocks 5 drive the L-shaped hook plates 6 closer to each other. In this way, the L-shaped hook plates 6 abut the outer surface of the snap-in strips 24, thereby driving the two reinforcement shells 2 to cling to the outer surfaces of the four copper bars 1, and also protecting the four sides of the four copper bars 1.

[0033] Specifically, flame-retardant silicone strips 11 are filled between the separator bars 22. Advantageously, by attaching the flame-retardant silicone strips 11 to the outer surface of the copper busbar 1, insulation can be further enhanced. Furthermore, the flame-retardant silicone strips 11 can slow or prevent the spread of fire when exposed to high temperatures or fire, thereby protecting the electrical equipment within the busbar trunking and the safety of the entire system. The silicone strips have a certain degree of elasticity, absorbing and buffering vibrations and shocks that may be generated during operation of the busbar trunking, protecting it from damage. Together with the heat dissipation fins 23, they can effectively dissipate the heat generated by the copper busbar 1.

The advantage is that the edge banding 9 can be fixedly connected to the two ends of the cover plate 3 by using the matching screws. In this way, the reinforced housing 1 and the cover plate 3 can further protect the main part of the copper busbar 1, and the joint side guard 10 can protect the joints at both ends of the copper busbar 1.

[0035] When in use, first arrange the four groups of copper bars 1 and fit them together, then fit the two reinforcement shells 2 on both sides of the four copper bars 1, and then fit the cover plate 3 on the other two sides of the four copper bars 1, and then rotate the double-threaded rod 7 to drive the two fastening blocks 5 threadedly connected on their outer surfaces to move toward each other, so that the two fastening blocks 5 drive the L-shaped hook plates 6 to approach each other, so that the L-shaped hook plates 6 are against the outer surface of the clamping strip 24, thereby driving the two reinforcement shells 2 to be close to the outer surface of the four copper bars 1, and then use screws to fix the edge sealing plates 9 to the two ends of the cover plate 3 to complete the assembly of the bus duct.
