Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated substation power transmission and distribution equipment, specifically to a busbar trunking and prefabricated substation that is easy to assemble. Background Technology

[0002] As compact power distribution equipment, prefabricated substations have limited internal space. Therefore, traditional busbar trunking suffers from the following drawbacks during installation: the length and number of branches of traditional busbar trunking are fixed at the factory and cannot be flexibly adjusted according to the actual number of switches inside the substation. This necessitates custom-made specifications or on-site cutting and modification, increasing costs and construction time. Furthermore, existing busbar trunking often uses bolted segmented connections, requiring precise alignment of holes and segmented tightening during installation. This is difficult to operate within the confined space of the substation and can easily lead to overheating due to poor contact.

[0003] For example, Chinese patent CN223124557U discloses a heat-dissipating busbar trunking, including a busbar trunking body comprising multiple slots. Each slot contains one or more busbars, and heat-dissipating slots are provided between adjacent slots. The extension direction of the heat-dissipating slots is consistent with the extension direction of the slots, and the heat-dissipating slots are not connected to the slots on either side. By providing heat-dissipating slots between adjacent slots, heat dissipation between the slots can be achieved.

[0004] While the aforementioned heat-dissipating busbar trunking improves the safety of busbar trunking to some extent, it cannot meet the different branch numbers and length requirements in different prefabricated substations.

[0005] Based on this, this utility model designs a busbar trunking and box-type substation that is easy to assemble to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a busbar trunking and prefabricated substation that is easy to assemble.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A conveniently assembled busbar trunking includes a busbar trunking housing and conductive plates. The busbar trunking housing is composed of a first-end busbar enclosure frame, several middle-section busbar enclosure frames, and an end-end busbar enclosure frame that are detachably connected from right to left. The number of middle-section busbar enclosure frames can be changed according to the number of parallel switches in the transformer substation. Multiple sets of conductive plates can be detachably connected inside the first-end busbar enclosure frame, the middle-section busbar enclosure frame, and the end-end busbar enclosure frame. Connecting components are installed between adjacent conductive plates.

[0009] Furthermore, a connecting protrusion is fixedly connected to the upper left end of the first busbar enclosure frame, a connecting groove is provided on the upper right end of the middle busbar enclosure frame to be slidably connected to the connecting protrusion, a connecting protrusion is fixedly connected to the upper left end of the middle busbar enclosure frame, and a connecting groove is provided on the upper right end of the last busbar enclosure frame to be slidably connected to the connecting protrusion. Adjacent first busbar enclosure frames, middle busbar enclosure frames and last busbar enclosure frames are connected by connecting protrusions and connecting grooves.

[0010] Furthermore, a fixing hole for the connecting part is provided on the connecting protrusion and the connecting groove, and a thread is provided on the inner wall of the fixing hole for the connecting part. The adjacent first end busbar enclosure frame, middle section busbar enclosure frame and end busbar enclosure frame are fixedly connected by bolts passing through the fixing hole for the connecting part.

[0011] Furthermore, the conductive sheet has three sets, which are equidistantly staggered from top to bottom, and the conductive head is equidistantly staggered from right to left. The three sets of conductive sheets and the three sets of conductive heads correspond one-to-one. The front end of the conductive sheet is fixedly connected to the conductive head. The conductive head has an L-shaped structure and the front end of the conductive head extends forward.

[0012] Furthermore, the rear ends of the first busbar enclosure frame, the middle busbar enclosure frame, and the last busbar enclosure frame are fixedly connected to a rear end enclosure baffle. The front end of the rear end enclosure baffle is fixedly connected to a conductive sheet placement block. The number of conductive sheet placement blocks is the same as the number of conductive sheet groups and they correspond one-to-one. The conductive sheet placement block has a conductive sheet placement slot for inserting the conductive sheet. The front end of the conductive sheet placement block is fixedly connected to a conductive head baffle. The number of conductive head baffles is the same as the number of conductive head groups and they correspond one-to-one. The conductive head baffle has a U-shaped structure and is used to surround the outer wall of the conductive head to limit and fix it.

[0013] Furthermore, the connecting components include a clamping connecting block and an inclined connecting block. The left end of the conductive sheet in the closed frame of the first busbar is fixedly connected to the clamping connecting block, the right end of the conductive sheet in the closed frame of the middle busbar is fixedly connected to the inclined connecting block, the left end of the conductive sheet in the closed frame of the middle busbar is fixedly connected to the clamping connecting block, and the right end of the conductive sheet in the closed frame of the last busbar is fixedly connected to the inclined connecting block.

[0014] Furthermore, the clamping connecting block is made of wavy copper-aluminum alloy, and the tilting connecting block is made of downward tilting copper-aluminum alloy. The height of the right end of the tilting connecting block is lower than the height of the left end of the clamping connecting block. When the clamping connecting block and the tilting connecting block are close together, the arc-shaped part of the clamping connecting block will press against the upper end of the tilting connecting block.

[0015] Furthermore, the lower ends of the first busbar enclosure frame and the last busbar enclosure frame are respectively connected to fixing components;

[0016] Furthermore, the fixing components include connecting plates, connecting blocks, fixing blocks, and fixing plates. The lower ends of the first busbar enclosure frame and the last busbar enclosure frame are respectively fixedly connected to two sets of connecting plates symmetrically distributed front and rear. The lower ends of the connecting plates are fixedly connected to connecting blocks. The connecting blocks and fixing blocks are in a limiting sliding connection. The lower ends of the fixing blocks are fixedly connected to the fixing plates. The outer wall of the fixing plates is fixedly connected to the inner wall of the transformer substation.

[0017] In order to better achieve the purpose of this utility model, this utility model also provides a busbar trunking that is easy to assemble installed in the box-type substation. The busbar trunking is connected to the inner wall of the box-type substation through a connecting plate (231), a connecting block (232), a fixing block (233), and a fixing plate (234).

[0018] Compared with the prior art, the advantages of this utility model are as follows: 1. The number of groups of the middle busbar enclosure frame can be changed according to the number of parallel switches in the box-type substation. The modular design can adapt to different box-type substation structures, increasing the practicality and flexibility of the busbar trunking.

[0019] 2. The busbar modules are easy to assemble and disassemble, and the busbars are easy to install and remove from the inner wall of the transformer substation, which can adapt to the relatively small space inside the transformer substation. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A conveniently assembled busbar trunking includes a busbar trunking housing and conductive plates 17. The busbar trunking housing is composed of a first-end busbar enclosure frame 11, several middle-section busbar enclosure frames 12, and an end-end busbar enclosure frame 13 arranged sequentially from right to left and detachably connected. The number of middle-section busbar enclosure frames 12 can be changed according to the number of parallel switches in the transformer substation. Multiple sets of conductive plates 17 can be detachably connected inside the first-end busbar enclosure frame 11, the middle-section busbar enclosure frame 12, and the end-end busbar enclosure frame 13. Connecting components are installed between adjacent conductive plates 17.

[0032] A connecting protrusion 14 is fixedly connected to the upper left end of the first busbar enclosure frame 11. A connecting groove 15 is provided on the upper right end of the middle busbar enclosure frame 12, which is slidably connected to the connecting protrusion 14. A connecting protrusion 14 is fixedly connected to the upper left end of the middle busbar enclosure frame 12. A connecting groove 15 is provided on the upper right end of the last busbar enclosure frame 13, which is slidably connected to the connecting protrusion 14. The adjacent first busbar enclosure frames 11, middle busbar enclosure frames 12 and last busbar enclosure frames 13 are connected by the connecting protrusion 14 and the connecting groove 15.

[0033] A connecting part fixing hole 16 is provided on the connecting protrusion 14 and the connecting groove 15. The inner wall of the connecting part fixing hole 16 is threaded. The adjacent first end busbar enclosure frame 11, middle section busbar enclosure frame 12 and end busbar enclosure frame 13 are fixedly connected by bolts passing through the connecting part fixing hole 16.

[0034] The conductive sheet 17 has three sets, which are distributed at equal intervals from top to bottom. The conductive head 18 is distributed at equal intervals from right to left. The three sets of conductive sheets 17 and the three sets of conductive heads 18 correspond one-to-one. The front end of the conductive sheet 17 is fixedly connected to the conductive head 18. The conductive head 18 has an L-shaped structure and the front end of the conductive head 18 extends forward.

[0035] The front end busbar enclosure frame 11, the middle section busbar enclosure frame 12, and the rear end busbar enclosure frame 13 are fixedly connected to a rear end enclosure baffle 26. The front end of the rear end enclosure baffle 26 is fixedly connected to a conductive sheet placement block 20. The number of conductive sheet placement blocks 20 is the same as that of conductive sheets 17 and they correspond one-to-one. The conductive sheet placement block 20 has a conductive sheet placement slot 21 for inserting into the conductive sheet 17. The front end of the conductive sheet placement block 20 is fixedly connected to a conductive head baffle 22. The number of conductive head baffles 22 is the same as that of conductive heads 18 and they correspond one-to-one. The conductive head baffle 22 has a U-shaped structure and is used to surround the outer wall of the conductive head 18 to limit and fix it.

[0036] The front ends of the first busbar enclosure frame 11, the middle busbar enclosure frame 12 and the last busbar enclosure frame 13 are fixedly connected to a front end enclosure baffle 25. The front end enclosure baffle 25 is provided with a conductive head avoidance hole 27 for avoiding the front ends of the three sets of conductive heads 18.

[0037] The connecting assembly includes a clamping connecting block 191 and an inclined connecting block 192. The left end of the conductive sheet 17 in the first busbar enclosure frame 11 is fixedly connected to the clamping connecting block 191. The right end of the conductive sheet 17 in the middle busbar enclosure frame 12 is fixedly connected to the inclined connecting block 192. The left end of the conductive sheet 17 in the middle busbar enclosure frame 12 is fixedly connected to the clamping connecting block 191. The right end of the conductive sheet 17 in the end busbar enclosure frame 13 is fixedly connected to the inclined connecting block 192.

[0038] The clamping connecting block 191 is a corrugated copper-aluminum alloy, and the inclined connecting block 192 is a downwardly inclined copper-aluminum alloy. The height of the right end of the inclined connecting block 192 is lower than the height of the left end of the clamping connecting block 191. When the clamping connecting block 191 and the inclined connecting block 192 are close together, the arc-shaped part of the clamping connecting block 191 will press against the upper end of the inclined connecting block 192.

[0039] In this utility model, with the cooperation of the connecting protrusion 14, the connecting groove 15 and the connecting fixing hole 16, the first end busbar enclosure frame 11, several middle busbar enclosure frames 12 and the last end busbar enclosure frame 13 can be fixedly connected end to end using bolts. During the installation of the first end busbar enclosure frame 11, the middle busbar enclosure frame 12 and the last end busbar enclosure frame 13, the adjacent first end busbar enclosure frames 11, the middle busbar enclosure frames 12 and the last end busbar enclosure frames 13 move closer to each other, so that the adjacent conductive pieces 17 move closer to each other, that is, the adjacent pressing connecting blocks 191 and the inclined connecting blocks 192 move closer to each other. After the first end busbar enclosure frame 11, the middle busbar enclosure frame 12 and the last end busbar enclosure frame 13 are installed, the arc-shaped part of the pressing connecting block 191 will press the upper end of the inclined connecting block 192, and the adjacent conductive pieces 17 will be connected.

[0040] The number of groups of the middle busbar enclosure frame 12 can be changed according to the number of parallel switches in the box-type substation. Furthermore, the first busbar enclosure frame 11, the middle busbar enclosure frame 12, and the last busbar enclosure frame 13 are installed using a quick-release structure. As a result, the busbar trunking can be applied to box-type substations with different structures and different numbers of parallel switches.

[0041] The conductive sheet 17 can be replaced and repaired by removing the front end sealing baffle 25. The conductive sheet placement block 20, the conductive sheet placement slot 21 and the conductive head baffle 22 work together to prevent the conductive sheet 17 from being misaligned.

[0042] Example 2: In some embodiments, such as Figure 4 and Figure 6 As shown, in a preferred embodiment of the present invention, the lower ends of the first busbar enclosure frame 11 and the last busbar enclosure frame 13 are respectively connected to fixing components 23.

[0043] The fixing component 23 includes a connecting plate 231, a connecting block 232, a fixing block 233, and a fixing plate 234. The lower ends of the first busbar enclosure frame 11 and the last busbar enclosure frame 13 are respectively fixedly connected to two sets of symmetrically distributed connecting plates 231. The lower end of the connecting plate 231 is fixedly connected to the connecting block 232. The connecting block 232 and the fixing block 233 are in a limited sliding connection. The lower end of the fixing block 233 is fixedly connected to the fixing plate 234. The outer wall of the fixing plate 234 is fixedly connected to the inner wall of the transformer.

[0044] The prefabricated substation is equipped with a busbar trunking that is easy to assemble. The busbar trunking is connected to the inner wall of the prefabricated substation via a connecting plate 231, a connecting block 232, a fixing block 233, and a fixing plate 234.

[0045] The connecting block 232 and the fixing block 233 are provided with fixing holes 235 that are slidably connected to the pin block. The connecting block 232 is fixedly connected to the fixing hole 235 through the pin block, thereby making the first busbar enclosure frame 11 and the last busbar enclosure frame 13 fixedly connected to the inner wall of the transformer.

[0046] In this utility model, the connecting block 232 on the connecting plate 231 is placed in the fixing block 233 on the fixing plate 234, and then the pin block is inserted into the fixing hole 235. This allows the first busbar enclosure frame 11 and the last busbar enclosure frame 13 to be fixedly connected to the inner wall of the box-type substation. This enables the quick and easy installation of the inner wall and busbar trough of the box-type substation, making it applicable to box-type substations.

[0047] Example 3: In some embodiments, such as Figure 3 As shown, in a preferred embodiment of the present invention, the rear closed baffle 26 has multiple sets of heat dissipation holes 24 that are equidistantly distributed on the left and right sides, and each set of heat dissipation holes 24 is equidistantly distributed on the top and bottom.

[0048] Heat dissipation fins corresponding to the heat dissipation holes 24 are fixedly connected to the rear end closed baffle 26 behind the heat dissipation holes 24, thereby increasing the heat dissipation effect by increasing the specific surface area.

[0049] In this invention, the heat dissipation efficiency can be increased by the heat dissipation holes 24 and heat dissipation fins on the rear closed baffle 26.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
