Description

Technical Field

[0001] This invention relates to the field of equalizing ring technology, specifically to a split-type adjustable combined equalizing ring and its method. Background Technology

[0002] In high-voltage transmission lines, the equalizing ring acts as an additional conductor, guiding the electric field lines around the high-voltage power line to make their distribution more uniform, reducing the potential difference between the two ends of the insulator, improving the surface electric field, and preventing flashover caused by excessively high local field strength.

[0003] In transmission lines, equipotential bonding rings are typically installed on the connecting plates of insulation strings. Each ring consists of a ring body and a support, with the support welded to the ring body to form a three-dimensional enclosed device. Small equipotential bonding rings are also installed on composite insulators. During construction, the large equipotential bonding ring must be fitted into the composite insulator and then fitted with the connecting plate, often causing interference between the large and small rings. Furthermore, the shielding height of the large equipotential bonding ring is fixed and cannot be adjusted according to the elevation angle of the composite insulator. The ring body and support are made of aluminum tubing, and their irregular three-dimensional shape makes transportation, installation, and maintenance difficult, leading to damage and deformation during transport. These limitations and shortcomings are further compounded by the equipotential bonding ring's susceptibility to bird damage during use. Therefore, we propose a split-type adjustable combined equipotential bonding ring and its design. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a split-type adjustable combined equalizing ring and its method, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a split-type adjustable combined pressure equalization ring, comprising a large pressure equalization ring body and a small pressure equalization ring body. Four large pressure equalization welding plates (first type) and two large pressure equalization welding plates (second type) are fixed to the inner side of the large pressure equalization ring body. Two of the four large pressure equalization welding plates (first type) form a group. A large pressure equalization bracket is bolted between the two large pressure equalization welding plates (first type). A fixing plate is bolted to each of the two large pressure equalization welding plates (second type). A positioning post is fixed to the top of one fixing plate, and a screw is rotatably mounted on the top of the other fixing plate. A fixing ring is slidably mounted on the outside of the positioning post. Another fixing ring is threaded onto the outside of the screw. Small pressure equalization brackets are fixed to the outer walls of both fixing rings. Two small pressure equalization welding plates are fixed to the inner side of the small pressure equalization ring body. The two small pressure equalization brackets are bolted to the two small pressure equalization welding plates respectively.

[0006] According to the above technical solution, the large equalizing ring is made of bent aluminum tube, and the ring is open. Two anti-halo balls are welded to the two ends of the large equalizing ring.

[0007] According to the above technical solution, the small equalizing ring is made of bent aluminum tube, and the ring body of the small equalizing ring is open, with semi-circular sealing balls at each of the two ends of the ring body.

[0008] According to the above technical solution, both large and small pressure equalizing supports are made of bent aluminum rods. Both ends of the large pressure equalizing support and the end of the small pressure equalizing support near the small pressure equalizing ring are flattened. A small pressure equalizing support, a fixing ring, a positioning post and a fixing plate constitute a support group, and a small pressure equalizing support, a fixing ring, a screw and a fixing plate constitute another support group.

[0009] According to the above technical solution, multiple mounting holes are provided on the outer walls of the four large equalizing welding plates and the two small equalizing welding plates, and the multiple mounting holes of the four large equalizing welding plates and the two small equalizing welding plates are used to adjust the installation height of the large equalizing bracket and the fixing plate.

[0010] According to the above technical solution, a bird-repelling device is provided at the large equalizing ring body. The bird-repelling device includes a notched track ring, which is fixed to the outside of the large equalizing ring body. A notched rotating ring is rotatably installed inside the notched track ring. Several round shafts are rotatably installed on the outside of the notched rotating ring, and torsion springs are provided between the round shafts and the outer wall of the notched rotating ring. A metal rod is fixed to the outside of the round shaft, and a wind-bearing plate is fixed to the outside of the metal rod.

[0011] According to the above technical solution, an abutment plate is fixed on the outer wall of the circular shaft, and several limiting plates are fixed on the outside of the notched rotating ring. The limiting plates are located on the movement trajectory of the abutment plate and are used to limit the position of the abutment plate.

[0012] According to the above technical solution, a notched ring shell is fixed to the outside of the notched swivel ring, and the notched ring shell is used to protect the round shaft.

[0013] According to the above technical solution, an arc-shaped telescopic rod is fixed to the outer wall of the notched annular shell, and several triangular locking rods are fixed to the top of the telescopic end of the arc-shaped telescopic rod. A flat groove is opened on the inner wall of the wind-bearing plate, and the triangular locking rods are engaged with the flat groove of the wind-bearing plate.

[0014] The method of using a split-type adjustable combination equalizing ring includes the following steps: S1. One large equalizing ring, two large equalizing supports, one small equalizing ring and two support sets can be packaged and transported separately and assembled on the construction site. S2. When installation is required, fix the two large equalizing brackets to a large equalizing ring with bolts, and then install the small equalizing ring on the large equalizing ring through the two bracket groups. After installation, it can be placed on the composite insulator for use. S3. When it is necessary to adjust the height of the small equalizing ring, the operator rotates the screw. Under the coordinated action of the screw, the positioning column and the two fixed rings, the screw drives the fixed ring on one side to move the small equalizing support and the small equalizing ring upward. S4. Staff will move the small pressure equalization ring to the position where the anti-dizziness effect is best.

[0015] This invention provides a split-type adjustable combined equalizing ring and its method. It has the following beneficial effects: (1) In this invention, a large equalizing ring, two large equalizing supports, a small equalizing ring and two support groups can be packaged and transported separately and assembled on the construction site, which is convenient for transportation and protects the appearance quality of the product. At the same time, the screw, positioning column and two fixing rings work together to drive the small equalizing support and the small equalizing ring to move upward, thereby achieving the purpose of adjustable shielding height of the small equalizing ring, ensuring that the small equalizing ring achieves the best anti-corona effect. The linear drive is achieved by rotating the screw. Compared with the traditional hole spacing adjustment or shim adjustment, stepless fine adjustment can be achieved. This mechanical structure can accurately control the millimeter-level displacement of the small equalizing ring, ensuring that it is at the "best anti-corona point" calculated by electric field simulation, directly improving the equalizing effect. At the same time, such adjustment mechanism is not a single point of force, but is carried out under the guidance and constraint of the positioning column. This ensures that the small equalizing ring does not wobble or rotate during the lifting process, avoiding changes in electrical clearance caused by shaking.

[0016] (2) In this invention, the multiple mounting holes of the four large equalizing welding plates and the two small equalizing welding plates can be adapted to the site requirements to install the large equalizing ring and the small equalizing ring at a suitable height, thereby ensuring that the installation height and balance of the large equalizing ring and the small equalizing ring can be adjusted according to the site terrain, thus ensuring the equalizing shielding effect and enabling it to perform at its best working condition; both the small equalizing ring and the large equalizing ring are open type, and the small equalizing ring and the large equalizing ring can be separated from the composite insulator through the opening of the small equalizing ring and the opening of the large equalizing ring, thereby facilitating maintenance by the staff.

[0017] (3) By setting up a bird-repelling device, the circular shaft drives the metal rod to rotate and forms a dynamic protective sector around the large and small equal pressure rings, making it difficult for birds to find a stable foothold on the large and small equal pressure rings, directly depriving birds of the physical conditions for nesting or roosting. At the same time, the reflective surface of the metal rod will flash and shake during rotation, thereby stimulating the birds' vision and further improving the bird-repelling effect. Meanwhile, the metal rod, notched rotating ring, notched ring shell, flat groove of the wind-bearing plate, triangular clamp, and arc-shaped telescopic rod work together to retract the metal rod and wind-bearing plate, which is conducive to the bird-repelling device being transported together with the large equal pressure ring. At the same time, the notched ring shell will protect the retracted metal rod and wind-bearing plate, avoiding the problem that the metal rod and wind-bearing plate are easily bent and deformed due to shaking during transportation.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please see Figures 1-10One embodiment of the present invention is a split-type adjustable combined pressure equalization ring, comprising a large pressure equalization ring body 1 and a small pressure equalization ring body 13. Four large pressure equalization welding plates 1-4 and two large pressure equalization welding plates 2-6 are fixed to the inner side of the large pressure equalization ring body 1. Two of the four large pressure equalization welding plates 1-4 form a group, and a large pressure equalization bracket 3 is bolted between the two large pressure equalization welding plates 1-4. Fixing plates 7 are bolted to both large pressure equalization welding plates 2-6. A positioning post 11 is fixed to the top of one fixing plate 7, and a screw 9 is rotatably mounted on the top of the other fixing plate 7. A fixing ring 8 is slidably mounted on the outside of the positioning post 11, and another fixing ring 8 is threadedly connected to the outside of the screw 9. Each of the two fixed rings 8 has a small equalizing support 10 fixed to its outer wall. A small equalizing support 10, a fixed ring 8, a positioning post 11 and a fixing plate 7 constitute a support group. A small equalizing support 10, a fixed ring 8, a screw 9 and a fixing plate 7 constitute another support group. Two small equalizing welding plates 12 are fixed to the inner side of the small equalizing ring body 13. The two small equalizing supports 10 are fixedly connected to the two small equalizing welding plates 12 by bolts. In the above structure, one large equalizing ring body 1, two large equalizing supports 3, one small equalizing ring 13 and two support groups can be packaged and transported separately and assembled on the construction site, which is convenient for transportation and protects the appearance quality of the product.

[0022] The large equalizing ring 1 is made of bent aluminum tube and has an open shape. Two anti-corona balls 5 are welded to the two ends of the large equalizing ring 1. The small equalizing ring 13 is also made of bent aluminum tube and has an open shape. Semi-circular sealing balls are provided at the two ends of the small equalizing ring 13. In the above structure, the small equalizing ring 13 and the large equalizing ring 1 can be separated from the composite insulator through the openings of the small equalizing ring 13 and the large equalizing ring 1, which facilitates maintenance by the staff.

[0023] Both large equalizing supports 3 and small equalizing supports 10 are made of bent aluminum rods. Both ends of the large equalizing support 3 and the end of the small equalizing support 10 near the small equalizing ring 13 are flattened. Multiple mounting holes are provided on the outer walls of the four large equalizing welding plates 4 and the two small equalizing welding plates 12. These mounting holes are used to adjust the installation height of the large equalizing supports 3 and the fixing plate 7. In the above structure, the multiple mounting holes can be adapted to the site requirements to install the large equalizing ring 1 and the small equalizing ring 13 at appropriate heights. This ensures that the installation height and balance of the large equalizing ring 1 and the small equalizing ring 13 can be adjusted according to the site terrain, thereby ensuring the equalizing shielding effect and enabling them to perform at their best.

[0024] In use, one large equalizing ring 1, two large equalizing supports 3, one small equalizing ring 13, and two support groups (one support group consists of a small equalizing support 10, a fixing ring 8, a positioning post 11, and a fixing plate 7; the other support group consists of a small equalizing support 10, a fixing ring 8, a screw 9, and a fixing plate 7) can be packaged and transported separately and assembled on-site for easy transportation and to protect the product's appearance. When installation is required, the two large equalizing supports 3 are bolted to one large equalizing ring 1, and then the small equalizing ring 13 is installed on the large equalizing ring 1 using the two support groups. The large equalizing ring 1 and the two large equalizing supports 3 are detachable. The small equalizing ring 13 and the two support groups are bolted to the large equalizing ring 1. This installation method avoids interference and collision. After installation, it can be placed on a composite insulator for use. When the height of the small equalizing ring 13 needs to be adjusted, the operator rotates the screw 9. Under the coordinated action of the screw 9, the positioning post 11, and the two fixing rings 8, the screw 9 drives the fixing ring 8 on one side to move the small equalizing bracket 10 and the small equalizing ring 13 upward, thereby achieving the purpose of adjustable shielding height of the small equalizing ring 13 and ensuring that the small equalizing ring 13 achieves the best anti-scanning effect. By rotating the screw 9 for linear drive, compared with the traditional hole spacing adjustment or shim adjustment, stepless fine adjustment can be achieved. This mechanical structure can precisely control the millimeter-level displacement of the small equalizing ring 13, ensuring that it is at the "optimal anti-scanning point" calculated by electric field simulation, directly improving the equalizing effect. At the same time, this adjustment mechanism is not a single-point force, but is carried out under the guidance and constraint of the positioning post 11. This ensures that the small equalizing ring 13 does not wobble or rotate during the lifting and lowering process, avoiding changes in electrical clearance caused by shaking.

[0025] It should be noted that the multiple mounting holes of the four large equalizing welding plates 14 and the two small equalizing welding plates 12 can be adapted to the site requirements to install the large equalizing ring 1 and the small equalizing ring 13 at appropriate heights. This ensures that the installation height and balance of the large equalizing ring 1 and the small equalizing ring 13 can be adjusted according to the site terrain, thereby ensuring the equalizing shielding effect and enabling them to perform at their best.

[0026] It should also be noted that both the small equalizing ring 13 and the large equalizing ring 1 are open-type, and can be detached from the composite insulator through the openings of the small equalizing ring 13 and the large equalizing ring 1, thus facilitating maintenance by the staff.

[0027] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, a bird-repelling device 2 is provided at the large equalizing ring 1. The bird-repelling device 2 includes a notched track ring 21, which is fixed to the outside of the large equalizing ring 1. A notched rotating ring 22 is rotatably installed inside the notched track ring 21. Several round shafts 26 are rotatably installed on the outside of the notched rotating ring 22, and torsion springs are provided between the round shafts 26 and the outer wall of the notched rotating ring 22. A metal rod 24 is fixed to the outside of the round shafts 26. The surface of the metal rod 24 is a reflective surface, and a wind-bearing plate 2 is fixed to the outside of the metal rod 24. 5. A contact plate 27 is fixed to the outer wall of the circular shaft 26. Several limiting plates 28 are fixed to the outside of the notched rotating ring 22. The limiting plates 28 are located on the movement trajectory of the contact plate 27. The limiting plates 28 are used to limit the position of the contact plate 27. Through the above structure, the circular shaft 26 drives the metal rod 24 to rotate and forms a dynamic protective sector around the large equalizing ring 1 and the small equalizing ring 13. This makes it difficult for birds to find a stable foothold on the large equalizing ring 1 and the small equalizing ring 13, directly depriving birds of the physical conditions for nesting or roosting.

[0028] A notched ring shell 23 is fixed to the outside of the notched swivel 22. The notched ring shell 23 is used to protect the round shaft 26. An arc-shaped telescopic rod 29 is fixed to the outer wall of the notched ring shell 23. Several triangular locking rods 210 are fixed to the top of the telescopic end of the arc-shaped telescopic rod 29. A flat groove is opened on the inner wall of the air-bearing plate 25. The triangular locking rods 210 are engaged with the flat groove of the air-bearing plate 25. Through the above structure, the notched ring shell 23 can protect the retracted metal rod 24 and the air-bearing plate 25, avoiding the problem that the metal rod 24 and the air-bearing plate 25 are easily bent and deformed due to shaking during transportation.

[0029] In use, under the elastic force of the torsion spring corresponding to the circular shaft 26, the circular shaft 26 drives the contact plate 27 to always abut against the limiting plate 28. The limiting plate 28 restricts the rotation trajectory of the circular shaft 26 through the contact plate 27, so that the circular shaft 26 drives the metal rod 24 and the wind-bearing plate 25 to be in a vertical state. At the same time, the wind-bearing plate 25 will be pushed by the wind force. The wind-bearing plate 25 drives the notched rotating ring 22 to rotate along the outside of the notched track ring 21 through the circular shaft 26, so that the circular shaft 26 drives the metal rod 24 to rotate and form a dynamic protective sector around the large equalizing ring 1 and the small equalizing ring 13. This makes it difficult for birds to find a stable foothold on the large equalizing ring 1 and the small equalizing ring 13, directly depriving birds of the physical conditions for nesting or roosting. At the same time, the reflective surface of the metal rod 24 will flash and shake during rotation, thereby stimulating the vision of birds and further improving the bird deterrent effect.

[0030] When it is necessary to retract the metal rod 24, the operator pushes the metal rod 24 downwards, causing it to retract between the notched rotating ring 22 and the notched ring shell 23. Simultaneously, the flat groove of the wind-bearing plate 25 moves to the triangular locking rod 210, which then engages with the groove. This restricts the position of the wind-bearing plate 25, thus confining the metal rod 24 between the notched rotating ring 22 and the notched ring shell 23. At this point, the purpose of retracting the metal rod 24 is achieved, facilitating the bird deterrent device 2 as it moves along with the large equalizing ring 1. When the metal rod 24 needs to be unfolded, the telescopic end of the arc-shaped telescopic rod 29 is moved, causing the telescopic end of the arc-shaped telescopic rod 29 to move the triangular locking rod 210 away from the flat groove of the air-bearing plate 25. At this time, the triangular locking rod 210 no longer restricts the air-bearing plate 25. Under the action of the torsion spring corresponding to the round shaft 26, the round shaft 26 drives the contact plate 27 to always abut against the limiting plate 28. The limiting plate 28 restricts the rotation trajectory of the round shaft 26 through the contact plate 27, so that the round shaft 26 drives the metal rod 24 and the air-bearing plate 25 to be in a vertical state.

[0031] It should be noted that the notched ring shell 23 protects the retracted metal rod 24 and the air-bearing plate 25. After the triangular locking rod 210 is inserted into the flat groove of the air-bearing plate 25, a rigid lock is formed, fixing the metal rod 24 between the notched rotating ring 22 and the notched ring shell 23, thus preventing the metal rod 24 and the air-bearing plate 25 from bending and deforming due to shaking during transportation.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
