Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a novel high-density busbar. Background Technology

[0002] Busbar trunking is one of the important equipment for power transmission and transformation. It is a new type of conductor that uses copper or aluminum as conductor and non-inert insulating material as support, and is then installed in a metal trough. It has many advantages such as large current capacity, convenient tapping, strong overload capacity, and convenient maintenance. It is widely used in large buildings, factories and other places with high power demand.

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

[0004] Most existing busbar connections use an external splicing method, where multiple individual busbars are arranged side-by-side, with their shells connected by a joint structure. This method occupies a large space and requires manual, precise alignment and fixing of the busbars, demanding a high level of skill from operators and increasing assembly difficulty and time. Moreover, the external splicing method results in numerous exposed connection points, leading to poor connection stability and reliability. Under stress or vibration, these connection points are prone to loosening, affecting the overall performance of the busbar.

[0005] In addition, the existing busbar trunking housing design has defects. It is formed by screwing together four side plates, which allows moisture and dust to easily enter the housing through the joints. Moreover, the side plates have enclosed grooves on all four sides, which can easily accumulate water or dust. Water accumulation increases the risk of dampness and corrosion of the busbar trunking, while dust accumulation will affect the heat dissipation performance of the busbar trunking.

[0006] For example, application number CN202220660574.1 discloses a double-section busbar trunking.

[0007] In view of the above, this utility model is hereby proposed. Utility Model Content

[0008] The purpose of this utility model is to provide a novel high-density busbar trunking system to address the technical problems in existing busbar trunking systems, which mostly employ external splicing methods. This requires manual and precise alignment and fixing of two sets of busbar trunking, demanding a high level of skill from operators, increasing assembly difficulty and time. Furthermore, the external splicing method results in numerous connection points, leading to poor stability and reliability, and affecting the overall performance of the busbar trunking. The various technical effects of the preferred solutions provided by this utility model are detailed below.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] This utility model provides a novel high-density busbar trunking, comprising a housing, connecting side plates, partitions, and busbars. The housing has a receiving cavity with openings at both ends, and the receiving cavity is divided into multiple receiving slots by the partitions. The busbars are arranged in a one-to-one correspondence with the receiving slots. The connecting side plates are disposed opposite to the opening ends of the housing to protect the joints of the busbars and are nested with the busbar connection structure. The housing and the connecting side plates are integrally formed.

[0011] Preferably, the separator comprises two square tube profiles to divide the accommodating cavity into three accommodating slots, and the busbars are in three sets, each installed in a corresponding accommodating slot to form an inner three-part structure.

[0012] Preferably, the top plate and bottom plate of the housing are L-shaped, and L-shaped connectors are provided at intervals on the horizontal sections of the two, and the connectors form partially open connection grooves with the top plate and the bottom plate respectively.

[0013] Preferably, the housing further includes a first reinforcing rib. The housing has a first side plate and a second side plate disposed opposite to each other. The first reinforcing rib is correspondingly disposed on the first side plate and the second side plate. Bolts pass through the first reinforcing rib on the first side plate, the first side plate, the partition, the second side plate, and the first reinforcing rib on the second side plate in sequence to fix the partition.

[0014] Preferably, the vertical section of the connector is positioned close to the first side plate.

[0015] Preferably, it further includes a second reinforcing rib, which is disposed on the first side plate and corresponds to the connector, and is connected to the first side plate by bolts.

[0016] Preferably, the joint of the busbar is connected to the busbar connection structure by a double-headed torque single bolt.

[0017] Preferably, the central axis of all the busbars is collinear with the central axis of the receiving cavity.

[0018] Preferably, the connecting side plate expands outward in a direction away from the opening end to form a bent structure.

[0019] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0020] This invention effectively avoids the technical problems of existing busbar trunking systems, which mostly use external splicing methods, requiring manual and precise alignment and fixing of two sets of busbar trunking. This demands a high level of operator skill, increases assembly difficulty and time, and results in numerous connection points, leading to poor stability and reliability, thus affecting the overall performance of the busbar trunking. This invention provides a novel high-density busbar trunking system, comprising a shell, connecting side plates, partitions, and busbars. The shell has accommodating cavities open at both ends, which are divided by partitions to form multiple accommodating slots. Each busbar corresponds to one of these slots. The connecting side plates are positioned opposite each other at the open ends of the shell, protecting the joints of the busbars and nested with the busbar connection structure. The shell and connecting side plates are integrally formed. This integrated design of the shell and connecting side plates improves overall mechanical strength, eliminates the need for manual alignment and fixing of the two sets of busbar trunking, simplifies the assembly process, reduces assembly difficulty and time, and lowers the risk of failure due to fewer connection points, thus improving the stability and reliability of the busbar trunking. In addition, the receiving cavity is divided into multiple receiving slots by partitions, and the busbars are set one-to-one with the receiving slots to form an internal splicing structure. This setting allows multiple busbars to be integrated into one housing, optimizing the space layout, improving space utilization, and also helping with heat dissipation, thereby improving the performance and service life of the busbar trunking.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-3 As shown, this utility model provides a novel compact busbar trunking. The novel compact busbar trunking provided by this utility model includes a housing 1, a connecting side plate 2, a partition 3, and a busbar 4. The housing 1 has a receiving cavity with openings at both ends. The receiving cavity is divided into multiple receiving slots by the partition 3. The busbar 4 is arranged in a one-to-one correspondence with the receiving slots. The connecting side plate 2 is arranged opposite to the opening end of the housing 1 to protect the joint part 41 of the busbar 4 and is nested with the busbar connection structure. The housing 1 and the connecting side plate 2 are integrally formed.

[0029] The housing 1 and connecting side plate 2 of this utility model adopt an integral molding design, which improves the overall mechanical strength. It eliminates the need for manual alignment and fixing of the housing 1 of the two sets of busbar trunking, simplifying the assembly process, reducing assembly difficulty and time. Furthermore, by reducing the number of external connection points, it lowers the risk of failure and improves the stability and reliability of the busbar trunking. In addition, the receiving cavity is divided into multiple receiving slots by the partition 3. The busbars 4 are arranged one-to-one with the receiving slots to form an internal splicing structure. This arrangement allows multiple busbars 4 to be integrated into one housing 1, optimizing the space layout, improving space utilization, and also aiding in heat dissipation, thereby improving the performance and service life of the busbar trunking.

[0030] Compared to the existing technology where the housing 1 is formed by splicing four side plates, moisture and dust can easily enter the housing 1 through the splicing seams, adversely affecting the busbar trunking. The housing 1 of this invention adopts a one-piece molding design, completely eliminating the possibility of moisture and dust entering the housing 1 through the splicing seams, thus improving the overall sealing and protection performance and reliability of the busbar trunking.

[0031] As an optional implementation, such as Figure 3As shown, the separator 3 includes two square tube profiles to divide the accommodating cavity into three accommodating slots. The busbars 4 are in three sets and are installed in the corresponding accommodating slots to form an inner three-part 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 receiving cavity into three receiving slots and to provide support for the busbar 4.

[0033] Compared to the external splicing method used in existing technologies, where each busbar trunking has an independent housing 1 connected to the others via a connecting structure, this method occupies a large space and has poor heat dissipation. In contrast, this invention uses a separator 3 to divide the accommodating cavity of one housing 1 into three accommodating slots. Within limited external dimensions, it fully utilizes the internal space, allowing the busbar trunking to integrate three closely arranged busbars 4, greatly improving space utilization, aiding heat dissipation, and enhancing the performance and lifespan of the busbar trunking.

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

[0035] Furthermore, there are four connectors 5, which are respectively located at the four ends 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. The third vertical section 52 of the connector 5 is arranged parallel to 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, for connection with the cover plate of the connector. Furthermore, the spacing between the connectors 5 facilitates drainage, preventing water accumulation on the surface of the housing 1 and protecting the busbar trunking from moisture damage.

[0037] As an optional implementation, it also includes a first reinforcing rib 6. The housing 1 has a first side plate 13 and a second side plate 14 disposed opposite to each other. The first reinforcing rib 6 is correspondingly disposed on the first side plate 13 and the second side plate 14. Bolts pass through the first reinforcing rib 6, 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 separators 3.

[0039] By passing bolts sequentially 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, the two partitions 3 are securely fixed inside the housing 1, thereby ensuring the stability of the relative position of the busbar 4 and the housing 1.

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

[0041] As an optional implementation, a second reinforcing rib 7 is also included. The second reinforcing rib 7 is disposed on the first side plate 13 and is disposed correspondingly to the connector 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 their ends are respectively connected to the two connecting pieces 5 located at the same end, so as to improve the structural strength of the first side plate 13 and at the same time provide a certain support for the connecting pieces 5.

[0043] A first reinforcing rib 6 corresponding to the second reinforcing rib 7 is also provided on the second side plate 14. Bolts are used to 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 housing 1, thereby improving the overall performance of the busbar trunking.

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

[0045] The double-headed torque single bolt provides sufficient clamping force, with an average rated clamping torque ≥90 N·m, to ensure that the pressure on the joint 41 is uniform and reliable.

[0046] As an optional implementation, the central axis of all busbars 4 is collinear with the central axis of the receiving cavity.

[0047] Since the housing 1 and the connecting side plate 2 are designed as a single piece, their relative positions are fixed, which improves the accuracy of the busbar 4 during the assembly process. There is no need to use positioning fixtures to ensure the alignment of the busbar 4 and the housing 1, which simplifies the positioning process of the busbar 4 assembly, improves the assembly accuracy, and ensures the overall performance and reliability of the busbar trunking.

[0048] As an optional implementation, the connecting side plate 2 expands outward in a direction away from the opening 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 design improves structural stability while increasing the contact area between the connecting side plate 2 and the busbar connection structure, thereby enhancing the stability and reliability of the connection.
