Technical Field

[0001] The present application belongs to the technical field of pressure equalizing rings, and in particular, relates to a double-layer pressure equalizing ring. Background Art

[0002] The grading ring is a ring-shaped hardware that improves the voltage distribution of insulator strings. According to different uses, the grading ring can be divided into arrester grading ring, lightning protection grading ring, insulator grading ring, transformer grading ring, high-voltage test equipment grading ring and power transmission and transformation line grading ring, etc. Its main function is voltage grading, which can evenly distribute the high voltage around the object to ensure that there is no potential difference between the various parts of the ring, thereby achieving the effect of voltage grading. It is used in high-rise buildings and is also widely used in the field of architectural design.

[0003] The utility model with the existing authorization announcement number CN217931902U discloses a double-layer grading ring. Although the grading ring can be fixed to the transformer bushing by means of a supporting structure, the fixation is more stable, the wind resistance is stronger, and it is not easy to be damaged by shaking. The diameter of the grading ring of the utility model is larger than that of an ordinary grading ring. When conducting a local discharge test in high-altitude areas, it is not easy to have a continuous discharge phenomenon, thereby ensuring the stable operation of the power grid. However, the double-layer grading ring only uses a bushing to connect to the transformer, and there is no stabilizing mechanism in the double-layer part, so that after long-term use, it is inevitable that the connecting parts will become loose, which will cause the double-layer grading ring to shake, resulting in the problem of the grading device falling from a high altitude.

[0004] To this end, we propose a double-layer pressure equalizing ring to solve the above problems. Utility Model Content

[0005] The purpose of this application is to solve the problem in the prior art that the double-layer part has no stabilizing mechanism, so that after long-term use, the connecting parts will inevitably become loose, causing the pressure equalizer to fall from a high altitude, and to propose a double-layer pressure equalizing ring.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A double-layer pressure-equalizing ring comprises a sleeve, wherein two first L-shaped plates and two second L-shaped plates are fixedly mounted on the outer surface of the sleeve respectively, a first ring body is fixedly mounted on the bottom surfaces of the two first L-shaped plates together, a second ring body is fixedly mounted on the upper surfaces of the two second L-shaped plates together, two fixing openings are provided on the outer surface of the first ring body and the outer surface of the second ring body, a nut is fixedly mounted on the inner wall of each group of the fixing openings, a fastening bolt is threadedly connected to the inner wall of each group of the nuts, one end of each group of the fastening bolts close to each other passes through the nut and is fixedly mounted with a bearing, a fastening half-ring is fixedly mounted on the outer ring of each group of the bearings, the two groups of the fastening half-rings are respectively located inside the first ring body and the second ring body, and one end of each group of the fastening bolts away from each other passes through the nut and is fixedly mounted with a handle.

[0008] Preferably, the outer surface of the sleeve is provided with a plurality of installation openings, and the installation openings are provided in at least two groups.

[0009] Preferably, first fastening blocks are fixedly mounted on the front and back sides of the first L-shaped plate, and the bottom surface of each group of the first fastening blocks is fixedly connected to the upper surface of the first ring body.

[0010] Preferably, second fastening blocks are fixedly mounted on both side surfaces of the second L-shaped plate, and the upper surface of each group of the second fastening blocks is fixedly connected to the bottom surface of the second ring body.

[0011] Preferably, first reinforcement blocks are fixedly mounted on the upper surfaces of the first L-shaped plates, and the side surfaces of two first reinforcement blocks close to each other are fixedly connected to the outer surface of the sleeve.

By setting the first fastening blocks 3, the purpose of fastening the connecting position between the first L-shaped plate 4 and the first ring body 2 can be achieved, thereby achieving the effect of improving the connectivity between the first L-shaped plate 4 and the first ring body 2, and minimizing the problem of separation of the first L-shaped plate 4 and the first ring body 2 during their use.

[0025] Two fixing openings 9 are provided on the outer surface of the first ring body 2 and the outer surface of the second ring body 7, and a nut 14 is fixedly installed on the inner wall of each group of fixing openings 9. Second fastening blocks 17 are fixedly installed on both side surfaces of the second L-shaped plate 8, and the upper surface of each group of second fastening blocks 17 is fixedly connected to the bottom surface of the second ring body 7. By setting the second fastening blocks 17, the connection position between the second L-shaped plate 8 and the second ring body 7 can be fastened, thereby achieving the effect of improving the connectivity between the second L-shaped plate 8 and the second ring body 7, and avoiding the problem of separation of the second L-shaped plate 8 and the second ring body 7 during their use.

[0026] The inner wall of each set of nuts 14 is threadedly connected with a fastening bolt 10, and the end of each set of fastening bolts 10 that is close to each other passes through the nut 14 and is fixedly installed with a bearing 16, and the upper surface of the first L-shaped plate 4 is fixedly installed with a first reinforcement block 11, and the side surfaces of the two first reinforcement blocks 11 that are close to each other are fixedly connected to the outer surface of the sleeve 1. By setting the first reinforcement block 11, the purpose of reinforcing the position of the first L-shaped plate 4 after connection can be achieved, thereby achieving the effect of improving the stability of the first L-shaped plate 4 and avoiding the problem of the first L-shaped plate 4 being separated from the sleeve 1 during use.

[0027] The outer ring of each group of bearings 16 is fixedly installed with a fastening half ring 6, and the bottom surface of the second L-shaped plate 8 is fixedly installed with a second reinforcement block 18. The side surfaces of the two second reinforcement blocks 18 close to each other are fixedly connected to the outer surface of the sleeve 1. By setting the second reinforcement blocks 18, the position of the second L-shaped plate 8 after connection can be reinforced, thereby achieving the effect of improving the stability of the second L-shaped plate 8 and avoiding the problem of the second L-shaped plate 8 being separated from the sleeve 1 during use.

[0028] The two groups of fastening half rings 6 are respectively located inside the first ring body 2 and the second ring body 7. Two stabilizing blocks 13 are fixedly installed on the outer surface of the fastening half rings 6. The side surfaces of each group of stabilizing blocks 13 that are close to each other are fixedly connected to the outer surface of the bearing 16. By setting the stabilizing blocks 13, the position of the bearing 16 can be stabilized, so that the bearing 16 can be used better and the problem of position movement of the bearing 16 during use can be avoided as much as possible.

[0030] The working principle of the utility model is as follows: when in use, the staff first sets the sleeve 1 where it needs to be used, and then fixes the sleeve 1 at the position where it is set under the action of the installation port 12. After the installation is completed, the staff rotates the handle 5 so that the fastening bolt 10 can be driven to rotate under the thread provided by the nut 14 under the rotation of the handle 5. The inner ring of the bearing 16 can be driven to rotate through the rotation of the inner ring of the bearing 16 and the rotation of the fastening bolt 10, which can drive the fastening half ring 6 to move. By moving the fastening half ring 6, it can contact the components at the installation position, so that the first ring body 2 and the second ring body 7 can be fastened and fixed, thereby improving the stability of the double-layer voltage equalizing ring, ensuring that the double-layer voltage equalizing ring can be used better, and avoiding as much as possible the problem that some of the original double-layer voltage equalizing rings, when installed and used, only use the sleeve to connect to the transformer, and the double-layer part has no stabilizing mechanism, so that after long-term use, the connecting parts will inevitably become loose, which will cause the double-layer voltage equalizing ring to shake, causing the voltage equalizer to fall from a high altitude.
