Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, and specifically refers to a busbar sliding support structure. Background Technology

[0002] In large substations using GIS equipment, when the busbars are relatively long, the axial deformation of the casing caused by thermal expansion and contraction is significant and the deformation is large. This may damage the internal conductive rods and insulation components, posing a significant threat to safe operation and maintenance.

[0003] In existing technology, when multiple busbars need to be installed in a "stacked" manner, the lower busbar is usually mounted on the ground or base using fixed brackets or other equipment, while the upper busbar is mounted parallel to the lower busbar using connecting plates or connecting brackets. All connections are rigid. Because the busbar housing is prone to axial deformation in outdoor environments, the connecting plates / connecting brackets will deform under stress, potentially causing the upper and lower busbars to become non-parallel, i.e., the internal conductive rods will no longer be parallel and will become misaligned. The consequences of this phenomenon are: (1) The conductive rod is deflected, and the distance between the conductive rod and the non-insulating part is less than the safe distance, resulting in discharge breakdown; (2) The insulation plate at the end of the busbar may break, posing a risk of insulation failure. Utility Model Content

[0004] The main purpose of this utility model is to provide a busbar sliding support structure to solve the problems existing in the prior art, so that the supported busbar can adapt to its own axial deformation and avoid damage to the support structure.

[0005] To achieve the above objectives, the solution of this utility model is: A busbar sliding support structure includes two sets of busbars that are vertically adjacent to each other, and a support assembly. Each set of busbars includes at least one first busbar and at least one second busbar. The second busbar and the first busbar are arranged vertically parallel, and a support assembly is provided between their adjacent ends. The support assembly includes a lower connector fixedly connected to the end flange of the first busbar and an upper connector fixedly connected to the end flange of the second busbar. A groove extending along the axial direction of the first busbar is provided above the lower connector. A sliding plate slidably engages within the groove at the lower end of the upper connector. Sliding pieces are provided between the upper and lower surfaces of the sliding plate and the inner wall of the groove to reduce friction.

[0006] Both sides of the lower connector are provided with side plates; the lower end of the side plate is fixedly connected to the lower connector, and the upper ends of the two side plates extend towards each other in the horizontal direction to form a limiting flange; the side plate and the lower connector enclose to form the sliding groove, and the distance between the limiting flanges is less than the width of the sliding plate.

[0007] Preferably, the upper surface of the lower connector is configured as a support plate, and connecting plates extending along the axial direction of the first generatrix are provided on both sides of the support plate, and the lower end of the side plate is fixedly connected to the connecting plate.

[0008] Preferably, the lower connector, the upper connector, and the side plate are all made of metal.

[0009] The sliding plate includes a first sliding plate disposed on the lower wall of the slide groove, and second sliding plates disposed on the upper walls of both sides of the slide groove; the lower surface of the slide plate is slidably engaged with the first sliding plate, and the upper surface of the slide plate is slidably engaged with the second sliding plates on both sides respectively.

[0010] Preferably, both the first sliding piece and the second sliding piece are made of polytetrafluoroethylene.

[0011] The lower end face of the lower connector and the upper end face of the upper connector are provided with a first arc surface and a second arc surface that respectively match the circumferential shape of the first busbar and the second busbar.

[0012] Both sets of busbars are equipped with connecting components for connecting axially adjacent busbars; the connecting components include end caps that are fixedly connected to the end flanges of the two end busbars respectively, and several telescopic rods connected between the opposite surfaces of the end caps.

[0013] Preferably, the connecting assembly further includes a connecting ring; the telescopic rod includes an outer rod and an inner rod; the two ends of the outer rod are respectively fixedly connected to the connecting ring and one end cap; one end of the inner rod is fixedly connected to the other end cap, and its other end is telescopically fitted inside the outer rod.

[0014] Preferably, the telescopic rods are arranged at equal angular intervals around the axis of the end cap.

[0015] After adopting the above technical solution, the present invention has the following technical effects: This invention improves the rigid connection between the ends of the busbars in the prior art by replacing it with a sliding support. This allows the lower first busbar to stably support the upper second busbar, maintaining their relative distance and parallelism. Furthermore, the sliding cooperation of the upper connector's slide plate within the groove above the lower connector compensates for the stress generated during the axial deformation of the busbars. The support assembly as a whole will not be deformed by axial stress, resulting in a more stable structure and a longer service life, thereby avoiding a series of safety risks. In addition, by setting a sliding plate, the friction between the slide plate and the groove can be reduced, making it less prone to jamming. Attached Figure Description

Detailed Implementation

[0022] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0023] refer to Figures 1 to 5 As shown, this utility model discloses a busbar sliding support structure, including two sets of busbars that are adjacent to each other, and a support component 1; The two sets of busbars each include at least one first busbar 2 and at least one second busbar 3; the second busbar 3 and the first busbar 2 are arranged vertically parallel to each other, and a set of support components 1 is provided between the adjacent ends of the two. The support assembly 1 includes a lower connector 11 fixedly connected to the end flange 21 of the first busbar 2 and an upper connector 12 fixedly connected to the end flange 31 of the second busbar 3. A groove 100 extending along the axial direction of the first busbar 2 is provided above the lower connector 11. A slide plate 121 slidingly engaged in the groove 100 is provided at the lower end of the upper connector 12. Sliding pieces are provided between the upper and lower surfaces of the slide plate 121 and the inner wall of the groove 100 to reduce friction.

[0024] Through the above solution, this utility model improves the rigid connection between the ends of the busbars in the prior art into a sliding support, so that the lower first busbar 2 can stably support the upper second busbar 3, maintaining the relative distance and parallel state between the two. It can also compensate for the stress generated by the axial deformation of the busbar through the sliding cooperation of the slide plate 121 of the upper connector 12 in the slide groove 100 above the lower connector 11. The support component 1 as a whole will not be deformed by axial stress, its structure is more stable and its service life is longer, thereby avoiding a series of safety risks. In addition, by setting the sliding plate, the friction between the slide plate 121 and the slide groove 100 can be reduced, making it less likely to jam.

[0025] The following are specific embodiments of the present invention.

[0026] Both sides of the lower connector 11 are provided with side plates 13; the lower ends of the side plates 13 are fixedly connected to the lower connector 11 by bolts, welding or other means, and the upper ends of the two side plates 13 extend towards each other in the horizontal direction to form limiting flanges 131; the side plates 13 and the lower connector 11 enclose each other to form the sliding groove 100, and the distance between the limiting flanges 131 is less than the width of the sliding plate 121, which plays the role of limiting and preventing detachment.

[0027] Furthermore, the upper surface of the lower connector 11 is configured as a support plate 111, and connecting plates 112 extending along the axis of the first generatrix 2 are provided on both sides of the support plate 111. The lower end of the side plate 13 is fixedly connected to the connecting plate 112. By extending to form a longer and wider connecting plate 112, the connection strength between the side plate 13 and the lower connector 11 can be improved.

[0028] Secondly, the lower connector 11, the upper connector 12, and the side plate 13 mentioned above are all made of metal materials to meet the requirements of structural strength and hardness.

[0029] The aforementioned sliding piece includes a first sliding piece 4 disposed on the lower wall of the slide groove 100, and a second sliding piece 5 disposed on the upper walls of both sides of the slide groove 100; the lower surface of the slide plate 121 is slidably engaged with the first sliding piece 4, and the upper surface of the slide plate 121 is slidably engaged with the second sliding pieces 5 on both sides respectively, thereby reducing the friction between the slide plate 121 and the slide groove 100.

[0030] Furthermore, both the first sliding piece 4 and the second sliding piece 5 mentioned above are made of polytetrafluoroethylene.

[0031] Meanwhile, the first sliding piece 4 and the second sliding piece 5 can be fixedly installed in the slide groove 100 by means of bolt locking, welding or other methods.

[0032] The lower end face of the lower connector 11 and the upper end face of the upper connector 12 are provided with a first arc surface 113 and a second arc surface 122 respectively matching the circumferential shape of the first busbar 2 and the second busbar 3, so as to achieve adaptive installation and ensure that the lower connector 11 and the upper connector 12 are respectively attached to the first busbar 2 and the second busbar 3.

[0033] Both of the above busbar sets are equipped with Figure 5 The connecting assembly 6 shown is used to connect axially adjacent busbars (i.e., the first busbar 2 or the second busbar 3). The connecting assembly 6 includes end caps 61 and 61' that are fixedly connected to the end flanges 21 and 31' of the two end busbars, respectively, and a plurality of telescopic rods 62 connected between the opposite faces of the end caps 61. Thus, through the telescopic structure of the telescopic rods 62, the axial deformation of the busbars can be adapted to avoid stress being applied between axially adjacent busbars.

[0034] Furthermore, the aforementioned connecting assembly 6 also includes a connecting ring 63; the telescopic rod 62 includes an outer rod 621 and an inner rod 622; the two ends of the outer rod 621 are respectively fixedly connected to the connecting ring 63 and one end cap 61; one end of the inner rod 622 is fixedly connected to the other end cap 61, and its other end is telescopically fitted inside the outer rod 621. Thus, when the end spacing of the busbars is large, the telescopic rod 62 can be fixed by the connecting ring 63 to prevent it from deforming under stress. Specifically, the connecting ends of the outer rod 621, the inner rod 622 and the corresponding end caps are respectively provided with a ring 64 and 64', which are used to lock in place with the flange hole of the end cap 61.

[0035] Meanwhile, the aforementioned telescopic rods 62 are arranged at equal angular intervals around the axis of the end cap to achieve uniform arrangement.

[0036] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
