Description

Technical Field

[0001] The invention relates to the technical field of bus ducts, and in particular to a novel intensive bus duct. Background Art

[0002] Bus duct is one of the important equipment for power transmission and transformation. It is a new type of conductor formed by using copper or aluminum as conductor, supported by non-inert insulating material, and then installed in a metal trough. It has many advantages such as large current capacity, convenient tapping, strong overload capacity, and easy maintenance. It is widely used in large buildings, factories and other places with large electricity demand.

[0003] The applicant has found that the prior art has at least the following technical problems:

[0004] Most of the existing multiple bus ducts are connected by external splicing, that is, multiple separate bus ducts are combined side by side, and their shells are connected by connecting structures, which takes up a lot of space and requires manual precise alignment and fixing of the bus duct, which requires a high level of technical skills of the operators and increases the difficulty and time of assembly. Moreover, due to the use of external splicing, the connection points are exposed and there are many of them, the connection stability and reliability are poor, and under stress or vibration, the connection points are easy to loosen, affecting the overall performance of the bus duct.

[0005] In addition, the existing bus duct shell design has defects. It is formed by four side panels screwed together, and moisture and dust can easily enter the shell through the joints. Moreover, the side panels form closed grooves on all sides, which are prone to water or dust accumulation. Water accumulation will increase the risk of moisture and corrosion of the bus duct, while dust accumulation will affect the heat dissipation performance of the bus duct.

[0006] For example, application number CN202220660574.1 discloses a double bus duct.

[0007] In view of this, the present invention is proposed. Summary of the invention

[0008] The purpose of the present invention is to provide a new type of dense bus duct to solve the technical problems that the existing bus duct splicing in the prior art mostly adopts the external splicing method, which requires manual precise alignment and fixation of two sets of bus ducts, requires high technical level of operators, increases assembly difficulty and assembly time, and the external splicing method leads to more connection points, poor stability and reliability, and affects the overall performance of the bus duct.

[0027] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0028] like Figure 1-Figure 3 As shown, the present invention provides a new type of intensive bus duct, which includes a shell 1, a connecting side plate 2, a partition 3 and a busbar 4. The shell 1 has a accommodating cavity with openings at both ends, and the accommodating cavity is divided by the partition 3 to form a plurality of accommodating slots, and the busbar 4 is arranged in a one-to-one correspondence with the accommodating slots; the connecting side plate 2 is relatively arranged at the open end of the shell 1, for protecting the joint part 41 of the busbar 4, and is nested and connected with the busbar connection structure; the shell 1 and the connecting side plate 2 are integrally formed.

[0029] The housing 1 and the connecting side plate 2 of the present invention adopt an integrated design to improve the overall mechanical strength. There is no need to manually align and fix the housings 1 of the two sets of bus ducts, which simplifies the assembly process, reduces the difficulty and time of assembly, and reduces the risk of failure due to the reduction in the number of external connection points, thereby improving the stability and reliability of the bus duct. In addition, the accommodating cavity is divided into a plurality of accommodating slots by a partition 3, and the busbars 4 are arranged one by one with the accommodating slots to form an internal splicing structure. In this way, a plurality of busbars 4 can be integrated in a housing 1, which optimizes the spatial layout, improves the space utilization, and also helps to dissipate heat, thereby improving the performance and service life of the bus duct.

[0030] Compared with the prior art housing 1 formed by splicing four side panels, moisture and dust can easily enter the housing 1 through the splicing seams, which has an adverse effect on the bus duct. The housing 1 of the present invention adopts an integrated molding design, which completely eliminates the possibility of moisture and dust entering the housing 1 through the splicing seams, and improves the overall sealing protection performance and reliability of the bus duct.

[0031] As an optional implementation, Figure 3 As shown, the separator 3 includes two square tube profiles to divide the accommodating cavity into three accommodating slots. The number of busbars 4 is three groups, which are respectively installed in the corresponding accommodating slots to form an internal three-piece structure.

[0032] Furthermore, the partitions 3 are evenly arranged along the height direction of the housing 1. The partitions 3 are used to divide the accommodating cavity into three accommodating slots and provide support for the busbar 4.

[0033] Compared with the external splicing method used in the prior art, each bus duct has an independent shell 1, and the shells 1 are connected to each other through a connecting structure, which occupies a large space and has a poor heat dissipation effect. The present invention divides the accommodating cavity of a shell 1 into three accommodating slots through a separator 3. Under limited external dimensions, the internal space is fully utilized, so that the bus duct can integrate three groups of closely arranged busbars 4, greatly improving space utilization, and also facilitating heat dissipation, thereby improving the performance and service life of the bus duct.

[0034] As an optional implementation, the top plate 11 and the bottom plate 12 of the housing 1 are L-shaped, and L-shaped connectors 5 are arranged at intervals on the horizontal sections of the two, and the connectors 5 form connecting grooves with the top plate 11 and the bottom plate 12 respectively.

[0035] Furthermore, the number of the connecting members 5 is four, and they are respectively arranged at four end positions of the first horizontal section 111 of the top plate 11 and the second horizontal section 121 of the bottom plate 12 .

[0036] The third horizontal section 51 of the connector 5 is connected to the first horizontal section 111 and the second horizontal section 121 by bolts, and the third vertical section 52 of the connector 5 is arranged in parallel with the first vertical section 112 of the top plate 11 and the second vertical section 122 of the bottom plate 12, so that a partially open connection groove is formed between the connector 5 and the top plate 11 and between the connector 5 and the bottom plate 12, which is used to connect with the cover plate of the connector. And because there is a spacing between the connectors 5, it is helpful to drain water, the surface of the housing 1 will not accumulate water, and moisture is prevented from damaging the bus duct.

[0037] As an optional embodiment, it also includes a first reinforcing rib 6, the shell 1 has a first side plate 13 and a second side plate 14 arranged opposite to each other, the first reinforcing rib 6 is correspondingly arranged on the first side plate 13 and the second side plate 14, and the bolts pass through the first reinforcing rib 6 on the first side plate 13, the first side plate 13, the partition 3, the second side plate 14 and the first reinforcing rib 6 on the second side plate 14 in sequence to fix the partition 3.

[0038] Furthermore, the first reinforcing rib 6 extends along the width direction of the first side plate 13 to cover the two partitions 3 .

[0039] The two partitions 3 are firmly fixed in the shell 1 by bolts passing through the first reinforcing rib 6 on the first side plate 13, the first side plate 13, the partition 3, the second side plate 14 and the first reinforcing rib 6 on the second side plate 14 in sequence, so as to ensure the stability of the relative position of the busbar 4 and the shell 1.

[0040] As an optional implementation, the vertical sections of the connecting member 5 are all arranged close to the first side plate 13 .

[0041] As an optional implementation, it further includes a second reinforcing rib 7, which is disposed on the first side plate 13, is disposed corresponding to the connecting member 5, and is connected to the first side plate 13 by bolts.

[0042] Furthermore, the second reinforcing ribs 7 are respectively arranged on both sides of the first side plate 13 , and the ends thereof are respectively connected to the two connecting members 5 located at the same end, so as to improve the structural strength of the first side plate 13 and at the same time, play a certain supporting role for the connecting members 5 .

[0043] A first reinforcing rib 6 corresponding to the second reinforcing rib 7 is also provided on the second side plate 14. Bolts pass through the second reinforcing rib 7, the first side plate 13, the partition 3, the second side plate 14 and the corresponding first reinforcing rib 6 in sequence to further increase the fixation of the two partitions 3. The multi-point connection method further enhances the connection strength and stability between the partition 3 and the shell 1, thereby improving the overall performance of the bus duct.

[0044] As an optional implementation, the joint portion 41 of the busbar 4 is connected to the busbar connection structure by a double-headed moment single bolt.

[0045] The double-headed moment bolt provides sufficient clamping force, and the average rated clamping torque is ≥90 N·m, so as to ensure that the pressure of the joint part 41 is uniform and reliable.

[0046] As an optional embodiment, the central axes of all busbars 4 are colinear with the central axis of the accommodating cavity.

[0047] Since the shell 1 and the connecting side plate 2 are of one-piece design, the relative position between the two is fixed, which improves the accuracy of the busbar 4 during the assembly process. There is no need to use positioning tooling to ensure the alignment of the busbar 4 and the shell 1, which simplifies the assembly positioning process of the busbar 4, improves the assembly accuracy, and ensures the overall performance and reliability of the bus duct.

[0048] As an optional implementation, the connecting side plate 2 expands outwardly in a direction away from the open end to form a bent structure.

[0049] Furthermore, the connecting side plate 2 is integrally connected to the first side plate 13 and the second side plate 14 respectively.

[0050] This arrangement improves the structural stability while increasing the contact area between the connecting side plate 2 and the busbar connecting structure, thereby improving the stability and reliability of the connection.
