Description

Technical Field

[0001] This utility model relates to the field of GIS busbar support technology, specifically a windproof and sand-proof sliding support for GIS busbars. Background Technology

[0002] The GIS busbar is the core conductive component of GIS. Its main function is to connect circuit breakers, disconnect switches, transformers and other equipment inside the GIS to realize the collection, distribution and transmission of power. The GIS busbar windproof and sandproof sliding bracket is a bracket device specially designed for GIS busbars. It has both sliding function and windproof and sandproof function.

[0003] The supports currently used for GIS busbars lack omnidirectional sliding adjustment capabilities, making it difficult to adapt to the displacement requirements of the busbars under complex working conditions. This can easily lead to localized stress concentration, which in turn can cause damage to the busbar structure.

[0004] Therefore, a windproof and sand-resistant sliding bracket for GIS busbars is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a windproof and sand-proof sliding support for GIS busbars to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a windproof and sand-proof sliding bracket for GIS busbars, comprising a sliding unit and a protective unit;

[0007] The sliding unit includes a sliding component and an anti-detachment component. When the GIS busbar slides due to the thermal stress released by thermal expansion and contraction, it can be released in all directions through the sliding component. The anti-detachment component is used to ensure that the sliding component can stably release the stress generated by the external GIS busbar.

[0008] The protective unit includes a protective component and a monitoring component. The protective component is used to cover the sliding unit to form a protective layer, and the monitoring component is used to monitor the displacement data of the external GIS busbar. When the GIS busbar is in use, it is installed on the top surface of the support through the sliding unit. Under the restriction of the sliding unit, the stress accumulated inside the GIS busbar can be released in all directions, avoiding stress damage to the GIS busbar and affecting its safe operation. Under the restriction of the protective unit, a good sliding environment can be provided for the sliding unit, avoiding the influence of external foreign objects and impurities on the sliding unit's sliding, thereby affecting the stress release of the GIS busbar. At the same time, the protective unit can monitor the displacement of the GIS busbar and determine the deformation state of the support.

[0009] Preferably, the sliding assembly includes a mounting frame, a support frame connected to the bottom of the mounting frame, a sliding cover connected to the outer wall of the support frame, a limit frame slidably connected inside the sliding cover, a stainless steel plate slidably connected to the bottom of the limit frame, and a support sleeved on the bottom of the stainless steel plate.

[0010] The mounting frame is connected to the GIS busbar via a third bolt group, the bearing frame is connected to the sliding cover via a second bolt group, and the support is connected to the bracket via a first bolt group.

[0011] Preferably, the anti-detachment component includes a sleeve block, an anti-detachment tube is sleeved inside the sleeve block, and a screw pin is sleeved inside the anti-detachment tube.

[0012] Preferably, the inner side of the limiting frame is slidably connected to the top surface of the stainless steel plate, and the outer wall of the limiting frame is slidably connected to the inside of the sliding cover. Under the restriction of the limiting frame, the support frame can slide laterally and longitudinally to release stress on the GIS busbar in all directions.

[0013] Preferably, the outer wall of the screw pin is threaded to the inside of the anti-detachment tube, and there are two screw pins symmetrically distributed along the center line of the anti-detachment tube. Under the constraint of the screw pin and the anti-detachment tube, the support frame can be prevented from detaching.

[0014] Preferably, the protective component includes a first mounting cover, a first rubber cover on the outside of the first mounting cover, a first pressure plate on the outside of the first rubber cover, a second rubber cover below the first rubber cover, a second mounting cover on the inside of the second rubber cover, and a second pressure plate on the outside of the second rubber cover.

[0015] The first mounting cover is connected to the first rubber cover and the first pressure plate by a fourth bolt group, and the second mounting cover is connected to the second rubber cover and the second pressure plate by a sixth bolt group;

[0016] The first rubber cover and the second rubber cover are connected by a fifth bolt group.

[0017] Preferably, the monitoring component includes a longitudinal pointer, and a lateral pointer is provided on the side of the longitudinal pointer near the first mounting cover.

[0018] Preferably, the first and second rubber covers are made of rubber. The second mounting cover is connected to the top surface of the bracket by the first bolt group. The first mounting cover is connected to the sliding cover. With the support of the first and second mounting covers, the first and second rubber covers can be installed outside the sliding unit to protect the sliding unit.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This windproof and sand-resistant sliding bracket for GIS busbars consists of a sliding unit. When the busbar experiences stress, it drives the mounting bracket and support frame to slide on a stainless steel plate. The support frame drives the sliding cover to slide longitudinally along the limiting frame. When the busbar slides laterally, the limiting frame slides directly on the stainless steel plate. The stainless steel plate ensures smooth sliding, and the anti-detachment tube prevents the limiting frame from falling off. Compared with traditional fixed or unidirectional sliding brackets, this structure can release busbar stress from all directions, avoiding localized tensile damage, while providing overall support for the busbar, improving operational reliability and safety, and reducing maintenance costs.

[0021] 2. This windproof and sand-resistant sliding support for GIS busbars consists of a protective unit as one component. To prevent impurities and foreign objects from corroding the sliding unit and affecting its sliding effect, the protective unit is protected by first and second rubber covers to ensure long-term stable operation. Furthermore, longitudinal and transverse pointers are installed on the outer sides of the two rubber covers via a fourth bolt group. When the busbar slides, causing the rubber covers to deform, monitoring equipment can be used to determine the busbar sliding trend and support deformation state by observing the pointer sliding position, with the support as a reference. Simultaneously, the toughness of the rubber covers can buffer busbar stress and help release some of the stress. Attached Figure Description

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model, which provides a windproof and sandproof sliding bracket for GIS busbars, including a sliding unit 1 and a protective unit 2;

[0032] The sliding unit 1 includes a sliding component and an anti-detachment component. When the GIS busbar 3 slides due to the thermal stress released by thermal expansion and contraction, it can be released in all directions through the sliding component. The anti-detachment component is used to ensure that the sliding component can stably release the stress generated by the external GIS busbar 3.

[0033] The protection unit 2 includes a protection component and a monitoring component. The protection component is used to cover the sliding unit 1 to form protection, and the monitoring component is used to monitor the displacement data of the external GIS busbar 3.

[0034] When in use, the GIS busbar 3 is installed on the top surface of the bracket 4 through the sliding unit 1. Under the restriction of the sliding unit 1, the stress accumulated inside the GIS busbar 3 can be released in all directions, avoiding stress damage to the GIS busbar 3 and affecting its safe operation. Under the restriction of the protection unit 2, a good sliding environment can be provided for the sliding unit 1, avoiding the influence of external foreign objects and impurities on the sliding of the sliding unit 1, thereby affecting the stress release of the GIS busbar 3. At the same time, the protection unit 2 can monitor the displacement of the GIS busbar 3 and determine the deformation state of the bracket 4.

[0035] Example 2

[0036] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as detailed below:

[0037] The sliding assembly includes a mounting frame 18, a support frame 17 connected to the bottom of the mounting frame 18, a sliding cover 15 connected to the outer wall of the support frame 17, a limit frame 14 slidably connected inside the sliding cover 15, a stainless steel plate 13 slidably connected to the bottom of the limit frame 14, a support 12 sleeved at the bottom of the stainless steel plate 13, the mounting frame 18 is connected to the GIS busbar 3 by a third bolt group 19, the support frame 17 is connected to the sliding cover 15 by a second bolt group 16, and the support 12 is connected to the bracket 4 by a first bolt group 11. The anti-detachment assembly includes a sleeve block 110, an anti-detachment tube 111 sleeved inside the sleeve block 110, and a screw pin 112 sleeved inside the anti-detachment tube 111.

[0038] The inner side of the limiting frame 14 is slidably connected to the top surface of the stainless steel plate 13, and the outer wall of the limiting frame 14 is slidably connected to the inside of the sliding cover 15. Under the restriction of the limiting frame 14, the bearing frame 17 can slide laterally and longitudinally to release stress on the GIS busbar 3 in all directions.

[0039] Among them, the outer wall of the screw pin 112 is threadedly connected to the inside of the anti-detachment tube 111. There are two screw pins 112, which are symmetrically distributed along the center line of the anti-detachment tube 111. Under the restriction of the screw pin 112 and the anti-detachment tube 111, the support frame 17 can be restricted from detachment.

[0040] When in use, the GIS busbar 3 is installed with the mounting bracket 18 via the third bolt group 19. The outer wall of the mounting bracket 18 is provided with a slot to accommodate GIS busbars 3 of different sizes and types. The sleeve 110, fixedly installed at the bottom of the support frame 17, is fitted onto the outer wall of the stainless steel plate 13 and the support 12. The anti-detachment tube 111 passes through the sleeve 110, and the screw pin 112 is threaded into the anti-detachment tube 111. At this time, the sliding cover 15 is fitted onto the outer wall of the limiting frame 14. Then, the support 12 is installed on the top surface of the bracket 4 through the first bolt group 11, thus completing the installation of the GIS busbar 3. When the GIS busbar 3 generates stress, it drives the mounting frame 18 and the support frame 17 fixedly installed at the bottom of the mounting frame 18 to slide on the top surface of the stainless steel plate 13. The support frame 17 drives the sliding cover 15 to slide longitudinally on the outer wall of the limiting frame 14 through the second bolt group 16. When the GIS busbar 3 slides laterally, the limiting frame 14 slides on the top surface of the stainless steel plate 13. Under the restriction of the stainless steel plate 13, the sliding surface is kept smooth, making the sliding smoother. Under the restriction of the anti-detachment tube 111, the limiting frame 14 is kept sliding on the top surface of the stainless steel plate 13, preventing it from falling off. Compared to traditional fixed or unidirectional sliding frames, this structure can release stress on the GIS busbar 3 in all directions, avoiding localized pulling damage to the GIS busbar 3. At the same time, the sliding unit 1 can support the GIS busbar 3 as a whole and be installed on the top of the bracket 4, ensuring the reliability and safety of the GIS busbar 3 operation and reducing maintenance costs.

[0041] Example 3

[0042] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below:

[0043] The protective assembly includes a first mounting cover 21, a first rubber cover 25 on the outside of the first mounting cover 21, a first pressure plate 23 on the outside of the first rubber cover 25, a second rubber cover 27 below the first rubber cover 25, a second mounting cover 29 on the inside of the second rubber cover 27, and a second pressure plate 211 on the outside of the second rubber cover 27. The first mounting cover 21 is connected to the first rubber cover 25 and the first pressure plate 23 by a fourth bolt group 22. The second mounting cover 29 is connected to the second rubber cover 27 and the second pressure plate 211 by a sixth bolt group 210. The first rubber cover 25 and the second rubber cover 27 are connected by a fifth bolt group 26. The monitoring assembly includes a longitudinal pointer 24, and a transverse pointer 28 is provided on the side of the longitudinal pointer 24 near the first mounting cover 21.

[0044] The first rubber cover 25 and the second rubber cover 27 are made of rubber. The second mounting cover 29 is connected to the top surface of the bracket 4 through the first bolt group 11. The first mounting cover 21 is connected to the sliding cover 15. With the support of the first mounting cover 21 and the second mounting cover 29, the first rubber cover 25 and the second rubber cover 27 can be installed outside the sliding unit 1 to protect the sliding unit 1.

[0045] When the stress generated by the sliding unit 1 on the GIS busbar 3 is released during use, in order to prevent external impurities and foreign objects from corroding the sliding unit 1 and thus affecting the sliding of the sliding unit 1, the sliding unit 1 can be completely covered with a first rubber cover 25 and a second rubber cover 27 for protection, so as to ensure the long-term stable and reliable operation of the sliding unit 1. When protected by the first rubber cover 25 and the second rubber cover 27, the first rubber cover 25 is fitted onto the outside of the first mounting cover 21 fixedly installed on the outer wall of the sliding cover 15, and then the first pressure plate 23 is placed on the outside of the first rubber cover 25. The first pressure plate 23, the first rubber cover 25 and the first mounting cover 21 are installed by the fourth bolt group 22. Since the second mounting cover 29 is installed on the top surface of the bracket 4 by the first bolt group 11, the second rubber cover 27 is fitted onto the outer wall of the second mounting cover 29, and the second pressure plate 211 is placed on the outside of the second rubber cover 27. The second pressure plate 211, the second rubber cover 27 and the second mounting cover 29 are installed by the sixth bolt group 210. Then the first rubber cover 25 and the second rubber cover 27 are connected and installed by the fifth bolt group 26. Thus, the sliding unit 1 can be protected by the first rubber cover 25 and the second rubber cover 27. Then, the longitudinal pointer 24 and the transverse pointer 28 are installed on the outside of the first rubber cover 25 and the second rubber cover 27 through the fourth bolt group 22. When the GIS busbar 3 slides through the sliding unit 1, it causes the first rubber cover 25 and the second rubber cover 27 to deform. By using the sliding position of the longitudinal pointer 24 and the transverse pointer 28 and cooperating with the monitoring equipment, and taking the bracket 4 as the reference point, the sliding trend data of the GIS busbar 3 is judged, and the deformation state of the bracket 4 is judged. When the first rubber cover 25 and the second rubber cover 27 deform, their toughness can buffer the stress of the GIS busbar 3 and release part of the stress of the GIS busbar 3.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
