Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure is more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0035] As described above, in a conventional power distribution cabinet, in order to achieve phase-to-phase isolation between busbars, special developed insulation components, such as insulation grids of specific specifications and models, are required. These insulation components are installed independently or with additional support structures in the power distribution cabinet, which has poor application flexibility and has problems such as large space occupation, high cost, and complicated assembly.

[0036] Embodiments of the present disclosure provide a busbar support device and a power distribution cabinet. In the busbar support device, a first support member and a second support member are spaced apart. A plurality of first grooves are respectively provided on adjacent sides of the first support member and the second support member. A plurality of second grooves are respectively provided on top and bottom of the first support member and the second support member. The plurality of first grooves are respectively used to fix a plurality of busbars between the first support member and the second support member. The plurality of second grooves are respectively used to fix a plurality of phase insulation partitions between the busbar support device and another busbar support device. A plurality of external insulation sleeves are provided between the first support member and the second support member and respectively correspond to the plurality of second grooves. A plurality of connecting assemblies are respectively penetrated through the plurality of external insulation sleeves and coupled to the first support member and the second support member. With this arrangement, the busbar support device can not only fix a plurality of busbars, but also fix a plurality of phase insulation partitions. In use, the phase insulation function can be realized on the busbar support device without relying on specially developed insulation components, which is conducive to cost control and installation convenience, and can also save space in the cabinet. The principles of the present disclosure will be described in detail below with reference to the accompanying drawings. Figures 1 to 5

[0037] As shown in Figure 1 and Figure 2 , the busbar support device 100 includes a first support member 10a, a second support member 10b, a plurality of external insulation sleeves 21, and a plurality of connecting assemblies 30. The first support member 10a and the second support member 10b are kept at a certain interval, which can provide a basis for the installation of other components. A plurality of first grooves 11 are respectively provided on adjacent sides of the first support member 10a and the second support member 10b. A plurality of busbars 220 can be respectively inserted into the plurality of first grooves 11 of the first support member 10a and the second support member 10b, thereby fixing the plurality of busbars 220 between the first support member 10a and the second support member 10b. In this way, the busbars 220 will not displace during use, thereby ensuring the reliability and safety of power transmission.

[0038] As an example, the plurality of first grooves 11 can be rectangular grooves. With this arrangement, a plurality of rectangular busbars 220 can be provided between the first support member 10a and the second support member 10b, and the plurality of rectangular busbars 220 are respectively inserted into the plurality of rectangular grooves.

[0039] As another example, the plurality of first grooves 11 can be special-shaped grooves. With this arrangement, a plurality of irregularly shaped busbars 220, such as K-shaped busbars, can be provided between the first support member 10a and the second support member 10b, and the plurality of irregularly shaped busbars 220 are respectively inserted into the plurality of special-shaped grooves.

[0040] ​As another example, the shapes of the plurality of first grooves 11 combine the features of rectangular grooves and irregularly shaped grooves. For example, the first grooves 11 include both rectangular and irregularly shaped areas. In this way, not only rectangular busbars 220 but also busbars 220 of other irregular shapes can be installed between the first support member 10a and the second support member 10b, thereby improving the compatibility of the busbar support device 100.

[0041] like Figure 1 and Figure 2 As shown, multiple second grooves 12 are provided at the top and bottom of the first support member 10a and the second support member 10b, respectively. The function of the multiple second grooves 12 is to fix the interphase insulating partitions 230. The interphase insulating partitions 230 are partitions made of insulating material and can be installed between adjacent busbars 220 or on both sides of the busbars 220, thereby enhancing the insulation performance between adjacent busbars 220 and the insulation performance between the busbars 220 at the edge and the cabinet body 240 of the distribution cabinet 200. By fixing the multiple interphase insulating partitions 230 in the multiple second grooves 12, electrical short circuits or other safety accidents caused by the close distance between the busbars 220 can be prevented.

[0042] like Figures 1 to 3 As shown, multiple outer insulating sleeves 21 are disposed between the first support member 10a and the second support member 10b and correspond to the multiple second grooves 12, respectively. Multiple connection assemblies 30 are respectively inserted into the multiple outer insulating sleeves 21, and each connection assembly 30 is coupled to the first support member 10a and the second support member 10b at both ends, forming a stable connection structure. In this way, the outer insulating sleeves 21 provide insulation protection for the connection assembly 30, ensuring that electrical short circuits or leakage do not occur at the connection assembly 30. In addition, interphase insulating partitions 230 are disposed at the top of the first support member 10a and the second support member 10b, and interphase insulating partitions 230 are also disposed at the bottom of the first support member 10a and the second support member 10b. The area between the two interphase insulating partitions 230 is enclosed by the outer insulating sleeves 21. Therefore, an insulating layer is provided along the entire height direction between two adjacent busbars 220, thereby improving the electrical safety between the busbars 220.

[0043] With this arrangement, the busbar support device 100 can not only secure multiple busbars 220, but also multiple interphase insulation partitions 230. During use, without relying on specially developed insulation components, by upgrading the busbar system structure and components, the interphase isolation function can be achieved on a universal busbar support device, which helps control costs, improves installation convenience, and saves space within the cabinet.

[0044] In some embodiments, as Figures 1 to 3As shown, a third groove 210 is provided at the top and bottom of each outer insulation sleeve 21, and the third groove 210 corresponds to the second groove 12 on the first and second supports 10a, 10b. Specifically, the third groove 210 at the top of the outer insulation sleeve 21 corresponds to the corresponding second groove 12 at the top of the first and second supports 10a, 10b, thereby forming a continuous groove at the top of the first support 10a, the outer insulation sleeve 21, and the second support 10b. In addition, the third groove 210 at the bottom of the outer insulation sleeve 21 corresponds to the corresponding second groove 12 at the bottom of the first and second supports 10a, 10b, thereby forming another continuous groove at the bottom of the first support 10a, the outer insulation sleeve 21, and the second support 10b.

[0045] In this way, after the busbars 220 and the busbar support device 100 are fixed in the power distribution cabinet 200, the phase-to-phase insulation partition 230 can be inserted and fixed in the grooves at the front or rear side of the power distribution cabinet 200. The phase-to-phase insulation partition 230 is pullably inserted into the corresponding second groove 12 and the third groove 210, improving the assembly efficiency of workers. In addition, the phase-to-phase insulation partition 230 can be firmly fixed between the outer insulation sleeve 21 and the support, and a continuous insulation layer can be formed between the busbars 220, thereby enhancing the electrical insulation performance between adjacent busbars 220.

[0046] In some embodiments, as shown in Figure 1 and Figure 2 , two protruding ribs 211 are respectively provided at the top and bottom of each outer insulation sleeve 21. The two protruding ribs 211 are spaced apart, and a third groove 210 can be formed between the two protruding ribs 211. In this way, the phase-to-phase insulation partition 230 can be inserted and fixed between the two protruding ribs 211. In addition, at the position where the phase-to-phase insulation partition 230 and the outer insulation sleeve 21 contact, the insulation structure is partially overlapped to ensure its continuity, thereby enhancing the electrical insulation performance between adjacent busbars 220.

[0047] In some embodiments, as shown in Figure 2 and Figure 3 , a plurality of limiting seats 13 are respectively provided at the adjacent sides of the first and second supports 10a, 10b, and each limiting seat 13 is inserted into the corresponding outer insulation sleeve 21. With this arrangement, the limiting seat 13 can limit the movement of the outer insulation sleeve 21, preventing it from shifting or loosening when subjected to external forces or vibrations, thereby increasing the structural stability of the busbar support device 100.

[0048] In some embodiments, as shown in Figure 2 and Figure 3As shown, the limiting seat 13 comprises an error-proof structure, such as an edge or a circular arc structure arranged on the outer side wall of the limiting seat 13. When the limiting seat 13 is inserted into the outer insulation sleeve 21, the abutting angle of the limiting seat 13 and the outer insulation sleeve 21 is unique. At this angle, the second groove 12 can be corresponded with the third groove 210. In this way, the installation efficiency of workers can be improved, and the structural stability of the busbar support device 100 can be increased.

[0049] In some embodiments, as shown in Figure 2 and Figure 3 The busbar support device 100 further comprises a plurality of inner insulation sleeves 22. The plurality of inner insulation sleeves 22 are respectively arranged in the plurality of outer insulation sleeves 21 and surround the plurality of connecting assemblies 30. In this way, the inner insulation sleeves 22 can further increase the insulation performance between the connecting assemblies 30 and the busbar 220. When the busbar 220 is irregularly shaped, the distance between the busbar 220 and the connecting assembly 30 is close, which can easily cause electrical safety hazards. In this case, it is necessary to provide the inner insulation sleeve 22 to provide an additional insulation layer, which can effectively prevent electrical short circuit or leakage phenomenon caused by too close distance.

[0050] In other embodiments, the inner insulation sleeve 22 can also be arranged according to actual needs to further improve the electrical safety and reliability of the device. With this arrangement, through multiple layers of insulation, the busbar support device 100 not only can stably operate in various complex electrical environments, but also can adapt to busbars 220 of different shapes and sizes, can expand its application range and flexibility, while avoiding the problems of large space occupation, high use cost, and complicated installation of special phase-to-phase isolation parts.

[0051] In some embodiments, as shown in Figures 1 to 3 The first support 10a and the second support 10b are respectively provided with a plurality of through holes 14. The connecting assembly 30 comprises a first threaded part 31, a second threaded part 32, and a double-headed threaded sleeve 33. In this way, the first support 10a and the second support 10b can be fixed together by the first threaded part 31, the second threaded part 32, and the double-headed threaded sleeve 33.

[0052] In one embodiment, the first threaded member 31 penetrates through the corresponding through hole 14 of the first support 10a and is inserted into the corresponding outer insulation sleeve 21. The second threaded member 32 penetrates through the corresponding through hole 14 of the second support 10b. The double-headed threaded sleeve 33 is arranged in the corresponding through hole 14 of the second support 10b and is detachably coupled to the corresponding first threaded member 31 and second threaded member 32. Here, the length of the first threaded member 31 is greater than the length of the second threaded member 32. In this way, the first threaded member 31 can pass through the outer insulation sleeve 21 from one side of the first support 10a and enter the double-headed threaded sleeve 33 on the side of the second support 10b, and the connection is achieved through the double-headed threaded sleeve 33 and the second threaded member 32. When there are other structures on the rear side of the power distribution cabinet 200 that hinder installation, the installation of the connection assembly 30 can be completed from the front side, improving the convenience and flexibility of installation.

[0053] In another embodiment, the first threaded member 31 penetrates through the corresponding through hole 14 of the second support 10b and is inserted into the corresponding outer insulation sleeve 21. The second threaded member 32 penetrates through the corresponding through hole 14 of the first support 10a. The double-headed threaded sleeve 33 is arranged in the corresponding through hole 14 of the first support 10a and is detachably coupled to the corresponding first threaded member 31 and second threaded member 32. Here, the length of the first threaded member 31 is greater than the length of the second threaded member 32. In this way, when there are other structures on the front side of the power distribution cabinet 200 that hinder installation, the installation of the connection assembly 30 can be completed from the rear side, also improving the convenience and flexibility of installation.

[0054] In another embodiment, the connection assembly 30 can include a first threaded member 31. The first threaded member 31 penetrates through the corresponding through hole 14 of the first support 10a and the corresponding through hole 14 of the second support 10b, thereby achieving the fastening connection of the first support 10a and the second support 10b.

[0055] In another embodiment, the connection assembly 30 can include a second threaded member 32. The second threaded member 32 penetrates through the corresponding through hole 14 of the first support 10a and the corresponding through hole 14 of the second support 10b, thereby achieving the fastening connection of the first support 10a and the second support 10b.

[0056] It should be understood that when there is a shielding structure at the installation position of the busbar support device 100, due to the greater length of the first threaded member 31, the first threaded member 31 can be inserted into the corresponding support after penetrating through the shielding structure. Or the first threaded member 31 and the second threaded member 32 can be respectively sunk into the corresponding through hole 14 of the first support 10a and the corresponding through hole 14 of the second support 10b, thereby avoiding the influence of the shielding at the installation position of the busbar support device 100.

[0057] Through the above examples, workers can choose the appropriate installation method according to the actual situation, avoiding installation difficulties caused by space limitations.

[0058] In some embodiments, as shown in Figure 1 and Figure 2 , the opposite ends of the first support 10a and the second support 10b are provided with connecting parts 15 for fixing the busbar support device 100 to the power distribution cabinet 200. Specifically, the connecting parts 15 can include some standardized interfaces or fixing points, such as bolt holes, buckles, card slots, limiting protrusions, etc. These connecting parts 15 can match the corresponding fixing points on the power distribution cabinet 200, and the busbar support device 100 can be fixed on the power distribution cabinet 200 through bolts, nuts or other fasteners. In this way, the busbar support device 100 can be conveniently disassembled and maintained, improving the maintainability and flexibility of the equipment.

[0059] The second aspect of the present disclosure provides a power distribution cabinet 200. As shown in Figure 4 and Figure 5 , the power distribution cabinet 200 includes a cabinet body 240, a plurality of busbars 220, a plurality of groups of phase-to-phase insulation partitions 230, and a plurality of busbar support devices 100 of any one of the above.

[0060] As shown in Figure 4 and Figure 5 , a plurality of busbar support devices 100 are installed in the cabinet body 240. Each busbar support device 100 is composed of a first support 10a and a second support 10b, which maintain a certain interval between them and are respectively provided with a plurality of first grooves 11 on the adjacent sides. A plurality of busbars 220 are respectively inserted into the plurality of first grooves 11 of the first support 10a and the second support 10b. In addition, each group of phase-to-phase insulation partitions 230 includes a plurality of phase-to-phase insulation partitions 230. Each group of phase-to-phase insulation partitions 230 is detachably coupled to the plurality of second grooves 12 on the adjacent two busbar support devices 100.

[0061] In this way, the plurality of busbar support devices 100 form a stable support structure in the cabinet body 240, which not only fixes the busbars 220, but also isolates each busbar 220 through the phase-to-phase insulation partitions 230. During use, without relying on specially developed insulation components, the phase-to-phase isolation function can be realized on the general busbar support device through the upgrading of the busbar system structure and components, which is conducive to controlling the cost and improving the installation convenience, and can also save the space in the cabinet.

[0062] In some embodiments, when arranging the busbars 220, the phase-to-phase insulation partition 230 occupies less space, so the physical distance between the busbars 220 can be reduced, thereby saving space in the power distribution cabinet 200. In addition, even if the busbars 220 have irregular shapes, the phase-to-phase insulation partition 230 can still meet the necessary electrical safety standards without increasing the distance between the busbars 220, thereby increasing the application range of the busbar support device 100.

[0063] In addition, in the power distribution cabinet 200, various support schemes can be formed by different combinations, thereby being applied to different scenarios, which is conducive to accurately controlling costs and improving installation convenience.

[0064] In some embodiments, as shown in Figure 4 and Figure 5 , the cabinet 240 includes a first side support 241 and a second side support 242. The first side support 241 and the second side support 242 are arranged side by side on both sides of the plurality of busbar support devices 100 and are detachably coupled to the plurality of busbar support devices 100. With this arrangement, the first side support 241 and the second side support 242 are detachably connected to the plurality of busbar support devices 100. When it is necessary to adjust or replace the busbar support devices 100, they can be quickly disassembled and reinstalled, improving work efficiency and flexibility.

[0065] In some embodiments, as shown in Figure 4 and Figure 5 , the first side support 241 and the second side support 242 are provided with a plurality of cooperating portions 243. The plurality of cooperating portions 243 can be detachably coupled to the connecting portions 15 of the first support 10a and the second support 10b of the plurality of busbar support devices 100.

[0066] Specifically, the connecting portion 15 of each busbar support device 100 can be flexibly fixed to any one of the plurality of cooperating portions 243, thereby achieving the installation of the busbar support device 100 in the cabinet 240. In addition, the number of the plurality of cooperating portions 243 is greater than the number of the plurality of busbar support devices 100. Therefore, each busbar support device 100 has a plurality of optional installation positions. In this way, the arrangement height and distance of the plurality of busbar support devices 100 between the first side support 241 and the second side support 242 can be flexibly adjusted to adapt to different electrical configuration requirements and space layout requirements.

[0067] In some embodiments, the plurality of cooperating portions 243 are equally spaced. In this way, the plurality of busbar support devices 100 can be evenly distributed in the entire cabinet 240, ensuring that the distance between two adjacent busbar support devices 100 is consistent.

[0068] In other embodiments, the spacing between the plurality of engaging portions 243 can also be different. Here, the spacing between the plurality of engaging portions 243 still needs to satisfy certain safety regulations. In this way, the non-equidistant arrangement can avoid other structures within the switchgear 200, and can provide more flexibility and adaptability.

[0069] In some embodiments, as shown in Figure 4 and Figure 5 , the connecting portion 15 can be a limiting slot, and the engaging portion 243 can be a limiting protrusion. In this way, the limiting protrusion can be inserted into the limiting slot, so as to realize the detachable connection between the busbar support device 100 and the first side support 241 and the second side support 242.

[0070] In other embodiments, the engaging portion 243 can be a limiting slot, and the connecting portion 15 can be a limiting protrusion. In this way, the limiting protrusion can be inserted into the limiting slot, so as to realize the same coupling function.

[0071] It should be understood that the limiting slot and the limiting protrusion can also be arranged on the first support 10a and the second support 10b at the same time, for example, the limiting slot is arranged on one side of the first support 10a and the second support 10b, and the limiting protrusion is arranged on the opposite side. In this way, the first support 10a and the second support 10b can be installed on the first side support 241 and the second side support 242 in different ways.
