Description

Technical Field

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

[0002] The common-enclosure busbar consists of connections between circuits, substations, small hydropower stations, generators, and transformers, and features a unique circular structure capable of providing current ratings up to 4000A and voltage ratings up to 10KV. The common-enclosure busbar is used for current transmission between the leads of generators below 100MW and the low-voltage side of the main transformer, or between the low-voltage side of the station service transformer for units of 75MW and above and high-voltage distribution equipment; it can also be used for generator AC / DC excitation circuits, substation power supply busbars, or power leads for other industrial and civil facilities.

[0003] Traditional common-enclosure busbars typically use insulators, hardware, and fasteners or screws to install and fix the copper busbar conductors. Each fixing point of each copper busbar conductor needs to be installed independently, which is cumbersome and involves a lot of repetitive work. Furthermore, the copper busbar conductors can only be inserted through mounting holes on the top of the enclosure or from one side of the enclosure. During insertion, the conductor busbar needs to be lifted to move it, making installation time-consuming and labor-intensive. In traditional common-enclosure busbar fixing methods, the copper busbar conductors are in direct or indirect contact with insulators, hardware, fasteners, or screws. Since most of these components, except for the insulators, are made of metal, in practical applications, partial or complete insulation of the copper busbar conductors, hardware, fasteners, or screws is required, such as by installing insulating sleeves on the copper busbars, increasing costs.

[0004] Therefore, it is necessary to explore how to modify the common busbar to improve installation efficiency and reduce installation costs. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1-3 , Figure 1 This is a front view structural schematic diagram of an embodiment of the common busbar provided by this utility model; Figure 2 This is a side view structural schematic diagram of an embodiment of the common busbar provided by this utility model; Figure 3 This is a schematic diagram of the bracket structure of one embodiment of the common busbar provided by this utility model.

[0025] In one specific embodiment, the common busbar includes a box body 1, an upper bracket 2 and a lower bracket 3 disposed within the box body 1. The upper bracket 2 and the lower bracket 3 are provided with support blocks 6, which are insulating support blocks. The upper bracket 2 and the lower bracket 3 support the two ends of the copper busbar conductor 4 through the support blocks 6.

[0026] By setting an upper bracket 2 and a lower bracket 3 in the housing 1, and setting support blocks 6 in each of them, the copper busbar conductor 4 is supported at both ends by using insulated support blocks 6. The copper busbar conductor 4 only contacts the support blocks 6. The support blocks 6 are made of insulating material, so no additional insulation treatment is required to ensure insulation performance, which can adapt to various insulation requirements. During installation, the copper busbar conductor 4 can be easily pushed in by simply aligning it with the support blocks 6 of the upper and lower brackets. Similarly, when disassembling, the copper busbar can be quickly pulled out, reducing workload and eliminating the need for hardware, fasteners and screws, thus saving the corresponding material and installation costs.

[0027] The setting of the support block 6 is not limited in this application. The upper bracket 2 and the lower bracket 3 can be set directly at the top and bottom of the box 1, and then the support block 6 can be set. Other structural settings can also be used.

[0028] To improve space utilization efficiency and increase the structural strength of the enclosure 1, and to avoid structural damage caused by directly setting brackets at the top and bottom, in one embodiment, the common busbar also includes support rods 5 set on the upper bracket 2 and the lower bracket 3. Multiple support blocks 6 are sleeved on the support rods 5. The two ends of the support rods 5 are connected to the support frames on the side of the enclosure 1. The spacing between adjacent support blocks 6 on the upper bracket 2 and the lower bracket 3 is equal.

[0029] By setting support rods 5 on the upper bracket 2 and the lower bracket 3, and connecting them to the side of the box body 1, the box body 1 can be horizontally strengthened while the support block 6 is being installed, thereby improving the structural strength. At the same time, there is no need to control the structure of the bracket; only the installation position needs to be controlled to control the installation height, which improves the convenience and reliability of installation, increases the space utilization efficiency of the box body 1, and provides convenience for the installation of the support block 6.

[0030] In this application, since it is necessary to fix the copper busbar conductor 4 to the support block 6, in order to improve the fixing efficiency and avoid slippage, in one embodiment, the common busbar further includes at least one annular groove for engaging the copper busbar conductor 4, which is provided perpendicular to the length direction of the support block 6 and the support rod 5.

[0031] By setting an annular groove, the copper busbar conductor 4 can be snapped into the annular groove. During the fixing of the copper busbar conductor 4, the fixing effect can be determined by judging whether it is located in the annular groove, thereby improving installation efficiency and reliability.

[0032] This application does not impose any restrictions on the structure, shape, or number of the annular grooves, but it is generally advisable to allow all copper busbar conductors 4 to be snapped together.

[0033] To further improve the insulation effect, in one embodiment, the common busbar further includes a flexible insulation layer disposed on the surface of the annular groove, the flexible insulation layer being a rubber layer or a soft plastic layer.

[0034] By setting a flexible insulating layer on the surface of the annular groove, a higher insulation effect can be achieved, so that the copper busbar conductor 4 can be placed directly in use without worrying about additional insulation issues.

[0035] This application does not impose any restrictions on the material, thickness, or deposition method of the flexible insulating layer.

[0036] To further reduce the resistance of the copper busbar conductor 4 entering and exiting and improve installation efficiency, in one embodiment, the common busbar also includes bearing seats 7 disposed at both ends of the support rod 5, and the support rod 5 is connected to the bearing seats 7 by bearings.

[0037] By setting bearing seats 7 at both ends of the support rod 5, the support rod 5 will rotate during the insertion and removal process. Therefore, the copper busbar conductor 4 can be pushed in or pushed out simply by aligning the position, which improves the efficiency of use.

[0038] This application does not impose any restrictions on the structure or installation method of the bearing housing 7.

[0039] In this application, the copper busbar conductor 4 is supported by brackets, and the arrangement of the brackets is not limited. In one embodiment, there are multiple upper brackets 2 and multiple lower brackets 3. Multiple upper brackets 2 are located on a first plane, and multiple lower brackets 3 are located on a second plane. The first plane is parallel to the second plane, and the upper brackets 2 are parallel to the lower brackets 3.

[0040] The bracket can be matched with several support blocks 6 according to the actual number of copper busbar conductors 4 to meet the requirements, such as three-phase or four-phase, single row or double row, etc., to further meet the adaptability of different usage scenarios; and the support blocks 6 and support rods 5 can rotate independently around the axis, so they will not affect or interfere with adjacent copper busbars when the copper busbar conductors 4 are installed; the bracket integrates support blocks 6, support rods 5 and bearing seats 7, and only the bracket needs to be fixed during installation.

[0041] It should be noted that the number of upper and lower brackets 3 can be selected according to the actual use. The length of each section of the common busbar is not fixed. It may be 2 meters, 3 meters, or other lengths. Moreover, the specifications of the copper busbar are also selected according to the actual current. It may be 10*100, 8*80, etc. The weight of copper busbars of different specifications is also different. Based on this, it is possible to use 3 lower brackets 3 and 1 or 2 upper brackets 2, or 32 lower brackets and 21 upper brackets, etc., to meet the actual needs.

[0042] This application does not limit the positional relationship between the upper bracket 2 and the lower bracket 3. The upper bracket 2 and the lower bracket 3 are arranged vertically correspondingly, or the upper bracket 2 and the lower bracket 3 are arranged horizontally and staggered, or other arrangements, etc.

[0043] To prevent other copper busbar conductors 4 from colliding during their entry and exit, in one embodiment, the common busbar further includes isolation elements disposed on the upper bracket 2 and the lower bracket 3 for isolating adjacent copper busbar conductors 4.

[0044] By setting up an isolator, adjacent copper busbar conductors 4 are isolated, preventing interference during the entry and exit of the copper busbar conductors 4 and improving the reliability of use.

[0045] This application does not impose any restrictions on the materials or installation methods of the isolation rooms.

[0046] Regarding the efficiency of the copper busbar conductor 4 entering and exiting the enclosure, in one embodiment, the common busbar further includes a mounting surface disposed on the side of the enclosure 1 for the copper busbar conductor 4 to enter and exit the enclosure 1, and the mounting surface is parallel to the length direction of the support rod 5.

[0047] By setting up an installation surface, entry and exit can be made through the installation surface, thus improving entry and exit efficiency.

[0048] This application does not impose any limitations on the structure, shape, or size of the mounting surface.

[0049] Since the support block 6 may move relative to the support rod 5, reducing safety, in order to improve safety, in one embodiment, the common busbar also includes limiting blocks disposed on the support rod 5 and located on both sides of the support block 6, for limiting the support block 6.

[0050] By setting a limiting block, the support block 6 is positioned to maintain its position, ensuring that the copper busbar conductor 4 remains in place within the housing 1 after installation on the support block 6, thus improving safety. If a position change is required, only the position of the limiting block needs to be adjusted.

[0051] This application does not impose any restrictions on the material, size, or installation method of the limit block; generally, insulating material can be used, i.e., an insulating limit block can be used.

[0052] In one embodiment, the common busbar includes a box 1, brackets, etc., with the brackets arranged in upper and lower layers inside the box 1, and the copper busbar conductors 4 installed and fixed between the upper and lower brackets.

[0053] Support frames are provided on the inner walls of both sides of the box 1 for mounting brackets.

[0054] The bracket consists of a support block 6, a support rod 5, and a bearing seat 7. The support block 6 is fitted onto the support rod 5, and the support rod 5 is equipped with bearing seats 7 at both ends to enable the support rod 5 to rotate around its axis. The bracket is installed and fixed inside the housing 1 by the bearing seats 7 at both ends.

[0055] The support block 6 is cylindrical with a central hole for fitting onto the support rod 5. An annular groove is provided in the middle of the support block 6, which can limit and fix the conductor copper busbar. A bearing can also be embedded in the support block 6 so that the support block 6 can rotate around the axis of the support rod 5 after it is installed on the support rod 5. The support block 6 can be made of insulating materials such as rubber, plastic, or ceramic.

[0056] The support rod 5 can be a cylindrical shape such as a round bar or a round tube.

[0057] The copper busbar conductor 4 only contacts the support block 6. The support block 6 is made of insulating material, which can ensure insulation performance without additional insulation treatment and adapt to various insulation requirements. When installing the copper busbar conductor 4, it is inserted from one side of the housing 1. Since the support rod 5 and support block 6 on the bracket can rotate, the copper busbar conductor 4 only needs to be aligned with the groove of the support block 6 on the upper and lower brackets. It can be easily pushed in by the rolling rotation of the insulating block and the insulating rod. Similarly, when disassembling, the copper busbar can be quickly pulled out, reducing the workload. Since the support of the copper busbar conductor 4 mainly relies on the lower bracket 3, the upper bracket 2 only serves to fix and limit the copper busbar conductor 4. The number of upper brackets 2 does not need to correspond one-to-one with the number of lower brackets 3. The number of upper brackets 2 can be reduced according to the actual situation. The spacing between the upper and lower brackets 3 is set according to the height of the copper busbar conductor 4 to ensure that the copper busbar conductor 4 is fixed and limited. This method saves parts such as hardware, fasteners and screws, thus saving the corresponding material and installation costs.

[0058] The bracket can be matched with several support blocks 6 according to the actual number of copper busbar conductors 4 to meet the requirements, such as three-phase or four-phase, single row or double row, etc., to further meet the adaptability of different usage scenarios; and the support blocks 6 and support rods 5 can rotate independently around the axis, so they will not affect or interfere with adjacent copper busbars when the copper busbar conductors 4 are installed; the bracket integrates support blocks 6, support rods 5 and bearing seats 7, and only the bracket needs to be fixed during installation.

[0059] The number of upper and lower brackets 3 can be selected according to the actual use. The length of each section of the common busbar is not fixed, it may be 2 meters or 3 meters, etc., and the specifications of the copper busbar are also selected according to the actual current, it may be 10*100 or 8*80, etc., and the weight of copper busbars of different specifications is also different. Based on this, it is possible to use 3 lower brackets 3 and 1 or 2 upper brackets 2, or 32 lower brackets and 21 upper brackets, etc., to meet the actual needs; or you can directly understand it as the main view, that the upper bracket 2 is set between the corresponding lower brackets 3.

[0060] The bearing seat 7 allows the support rod 5 to rotate, thereby driving the support block 6 to rotate. Even when the support block 6 does not rotate, the copper busbar conductor 4 can still enter and exit. When both the support rod 5 and the support block 6 can rotate, the efficiency of the copper busbar entering and exiting will be improved, and the copper busbars can be free from interference. Of course, the bearing seat 7 can also be removed, and the support rod 5 does not rotate. The copper busbar conductor 4 can still enter and exit without interference by only rotating the support block 6.

[0061] The copper busbar is fixed by the annular grooves of the upper and lower support blocks 6. The relative positions of the upper and lower brackets 3 are set according to the specifications of the copper busbar. The annular grooves of the upper and lower support blocks 6 can limit the copper busbar and ensure that the copper busbar is between the annular grooves. The surface of the annular groove can also be wrapped with a layer of flexible insulating material (such as rubber or soft plastic) to allow the copper busbar to have a certain amount of interference with the annular groove. The interference fit fixes the copper busbar.

[0062] The common busbar and copper busbar are installed in sections along the length. The ends of each copper busbar section are overlapped. After the final installation is completed, the two ends of the copper busbar in the entire common busbar are overlapped and fixed with the copper busbars reserved for the equipment at both ends.

[0063] The left and right positions of the support block 6 can be set according to actual needs (such as insulation electrical clearance); the support block 6 can also be fitted onto the support rod 5, and limit blocks can be set at both ends of the support block 6 to keep the support block 6 in the required position. The left and right positions of the support block 6 can be adjusted by adjusting the limit blocks.

[0064] In summary, the common busbar provided by this utility model embodiment, by setting an upper bracket and a lower bracket in the enclosure and setting support blocks respectively, and using insulated support blocks to support both ends of the copper busbar conductor, allows the copper busbar conductor to only contact the support blocks. The support blocks are made of insulating material, so no additional insulation treatment is required to ensure insulation performance, adapting to various insulation requirements. During installation, the copper busbar conductor can be easily pushed in by simply aligning it with the support blocks of the upper and lower brackets. Similarly, during disassembly, the copper busbar can be quickly pulled out, reducing workload and eliminating the need for hardware, fasteners, screws, and other parts, thus saving corresponding materials and installation costs.
