Description

Technical Field

[0001] The present invention relates to the technical field of insulators, and specifically to a self-cleaning UHV ceramic insulator. Background Art

[0002] In the power system, UHV ceramic insulators play a crucial role. They are widely used in transmission lines to ensure the safe transmission of electric current. However, traditional ceramic insulators face some challenges during use. In particular, the accumulation of dirt on the surface area can lead to a decline in their performance and even cause flashover accidents. This not only increases the cost of manual maintenance but also may affect the efficiency of power transmission.

[0003] To solve this problem, the industry has been committed to developing ceramic insulators with self-cleaning properties. Self-cleaning ceramic insulators can automatically remove the accumulated dirt on their surfaces through special treatments or designs on their surfaces, thereby reducing the cost of manual maintenance and improving the efficiency of power transmission. These special treatments or designs usually include applying a layer of coating with special properties on the surface of the insulator, such as a nano-molecular structure layer, a hydrophobic material, etc. These coatings can change the physical and chemical properties of the insulator surface, making it difficult for dirt substances to adhere or easier to be washed away by rainwater.

[0004] Although certain progress has been made in the technology of self-cleaning ceramic insulators, there are still some deficiencies in practical applications. For example, the structural design of some self-cleaning ceramic insulators is not reasonable enough, resulting in inconvenience during installation and use. In addition, some self-cleaning ceramic insulators are vulnerable to the invasion of pollutants such as dust during idle storage or turnover transportation, thereby affecting their self-cleaning performance and service life.

Detailed implementation manners

[0035] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear and understandable, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 14, the present invention provides a technical solution: a self-cleaning UHV ceramic insulator, including a self-cleaning ceramic insulator 1, the surface of the self-cleaning ceramic insulator 1 is specially treated or designed to be able to automatically remove the accumulated dirt on the surface, thereby reducing the manual maintenance cost and improving the power transmission efficiency of the ceramic insulator. Its characteristics include high strength, high toughness, wear resistance, corrosion resistance and excellent self-cleaning performance; by applying a layer of coating with special properties on the surface of the self-cleaning ceramic insulator 1, such as a nano-molecular structure layer, a hydrophobic material, etc., these coatings can change the physical and chemical properties of the insulator surface, making it difficult for dirt substances to adhere or easier to be washed away by rainwater; a connecting handle 2 is fixed at the top of the self-cleaning ceramic insulator 1, a wire slot 3 is opened on the top surface of the connecting handle 2, and a wire bundling plate 4 is arranged above the connecting handle 2. The wire bundling plate 4 is in an "Ω"-shaped plate structure; the connecting handle 2 is in a cylindrical structure, the wire slot 3 is in an arc-shaped groove, a rubber gasket 5 is fixed on the surface of the wire slot 3, and a rubber gasket 6 is fixed on the inner ring surface of the wire bundling plate 4. The thickness of the rubber gasket 6 is greater than the thickness of the rubber gasket 5. Screws 9 are fixed on the bottom surfaces of both end plates of the wire bundling plate 4. A side groove 7 is opened on the surface of the connecting handle 2. One end of the screw 9 is inserted into the side groove 7, and a nut 10 is sleeved and screwed at the bottom end of the screw 9. Traction plates 11 are fixed on both end plates of the wire bundling plate 4; there are two side grooves 7, and the two side grooves 7 are symmetrically distributed with respect to the connecting handle 2. A through hole 8 is opened on the top surface of the side groove 7, and the side groove 7 is inserted into the through hole 8. The rod length of the side groove 7 is greater than the height of the through hole 8; the traction plate 11 is in an arc-shaped plate structure, a through port 18 is opened on the surface of the traction plate 11, a card slot 19 is opened on the bottom surface of the through port 18, the card slot 19 is in an arc-shaped groove, a rubber sealing piece 20 is fixed on the top surface of the through port 18, and the bottom end of the rubber sealing piece 20 is inserted into the card slot 19. The width of the rubber sealing piece 20 is equal to the width of the through port 18.

[0037] During use, place the cable against the wire slot 3, and then press the wire bundling plate 4 against the cable. At this time, the screw 9 passes through the through hole 8 and extends into the side groove 7. Push the rubber sealing piece 20 with your finger. After the rubber sealing piece 20 deforms, its bottom end extends out from the rubber baffle 21. Then lift the rubber sealing piece 20, extend the nut 10 into the side groove 7 and sleeve and screw it on the screw 9. As the nut 10 is tightened, the wire bundling plate 4 is pulled by the screw 9 to tightly clamp the cable, realizing the clamping and fixing of the cable by the connecting handle 2 and the wire bundling plate 4. Then, move the bottom end of the rubber sealing piece 20 into the rubber baffle 21. At this time, the rubber sealing piece 20 covers the through port 18, that is, the exposure of the nut 10 and the screw 9 is reduced.

[0038] The bottom end of the traction plate 11 is fixed to the top surface of the connecting ring 12. A connecting sleeve 15 is rotatably connected below the connecting ring 12, and the connecting sleeve 15 is screwed to the connecting handle 2. The connecting ring 12 is in a circular plate-like structure, the inner ring diameter of the connecting ring 12 is larger than the top surface diameter of the connecting handle 2, a turntable 13 is fixed to the bottom surface of the connecting ring 12, the turntable 13 is in a ring plate with a "convex" cross-section, and the turntable 13 is rotatably connected in a limiting groove 14. The limiting groove 14 is opened on the top surface of the connecting sleeve 15, and the limiting groove 14 is in a ring groove with a "convex"-shaped break. The height of the connecting sleeve 15 is equal to the distance from the bottom surface of the side groove 7 to the bottom surface of the connecting handle 2. An internal thread 17 is provided on the inner ring surface of the connecting sleeve 15, and an external thread 16 is provided on the outer wall of the connecting handle 2. The external thread 16 is below the side groove 7, and the external thread 16 and the internal thread 17 are in mating connection.

[0039] During use, when the connecting handle 2 and the wire bundling plate 4 are used to clamp the cable, first, the connecting sleeve 15 is sleeved on the top of the connecting handle 2. Pushing the connecting sleeve 15 downward will not affect the insertion of the cable into the space between the connecting handle 2 and the wire bundling plate 4. Then, the cable is inserted between the connecting handle 2 and the wire bundling plate 4, and the connecting sleeve 15 is pulled along the connecting handle 2 until the connecting sleeve 15 reaches the external thread 16. During the process of screwing the connecting sleeve 15 down along the connecting handle 2, the external thread 16 and the internal thread 17 are in mating connection. And during the rotation of the connecting sleeve 15, the top of the connecting sleeve 15 rotates with the turntable 13 as an annular guide rail, that is, when the connecting sleeve 15 descends, it pulls the wire bundling plate 4 to descend through the turntable 13 and the connecting ring 12. When the storage groove 25 is screwed to the bottom end of the connecting handle 2 and the bottom surface of the storage groove 25 is coplanar with the bottom surface of the connecting handle 2, the through port 18 corresponds to the side groove 7, and the screw 9 passes through the corresponding through hole 8. The screw 9 is fixed in the side groove 7 by using a nut 10, so that the storage groove 25 is screwed to the connecting handle 2, and the wire bundling plate 4 is pulled by the traction plate 11 to clamp the cable, that is, the first connection structure between the wire bundling plate 4 and the connecting handle 2 is completed. And after the screw 9 extends into the side groove 7, it is locked by the nut 10 to realize the second connection structure for connecting the wire bundling plate 4 and the connecting handle 2. The connection between the wire bundling plate 4 and the connecting handle 2 is strengthened by two groups of connection structures to prevent the cable from loosening between the wire bundling plate 4 and the connecting handle 2.

[0040] The top surface of the connecting ring 12 is fixed with a rubber baffle 21. The rubber baffle 21 is in the shape of an arc-shaped plate structure. The inner ring diameter of the rubber baffle 21 is equal to the top surface diameter of the connecting handle 2. There are two rubber baffles 21, and the two rubber baffles 21 are symmetrically distributed about the inner ring opening of the connecting ring 12. After the first rubber gasket 5 is screwed onto the connecting handle 2, the rubber baffles 21 and the traction plate 11 are alternately distributed. The height of the rubber baffle 21 is greater than the height of the side groove 7, and the rubber baffle 21 shields the end groove body of the side groove 7; an embedding groove 22 is formed on the inner ring surface of the rubber baffle 21. The height of the embedding groove 22 is equal to the height of the rubber baffle 21. An elastic plastic strip 23 is fixed inside the embedding groove 22. The elastic plastic strip 23 is in the shape of an arc-shaped sheet. The inner ring diameter of the elastic plastic strip 23 is equal to the inner ring diameter of the rubber baffle 21. The elastic plastic strip 23 leans against one side of the connecting handle 2.

[0041] During use, the reason for installing the rubber baffle 21 on the top surface of the rubber sealing piece 20 is to cover the part of the side groove 7 not shielded by the traction plate 11 through the rubber baffle 21. That is, after the connecting sleeve 15 is screwed onto the bottom of the connecting handle 2, the rubber baffle 21 and the traction plate 11 cooperate with the rubber sealing piece 20 to jointly cover the side groove 7, preventing the screw 9 and the nut 10 from being corroded; and an elastic plastic strip 23 is installed on the inner ring side of the rubber baffle 21 to enable the rubber baffle 21 to always adhere to the surface of the connecting handle 2 when not being tensioned.

[0042] Two installation hoops 24 are sleeved on the top end of the self-cleaning ceramic insulator 1. An elastic protective cover 28 is arranged below the installation hoops 24. After the elastic protective cover 28 is unfolded, it is sleeved on the self-cleaning ceramic insulator 1. The installation hoop 24 is in the shape of an "Ω"-shaped plate structure. Through holes 26 are formed on the end plates of the two installation hoops 24. After the two installation hoops 24 are sleeved on the top end of the self-cleaning ceramic insulator 1, bolts 27 are inserted into the through holes 26 of the end plates of the two installation hoops 24. After the bolts 27 are tightened, the two installation hoops 24 tightly clamp the top end of the self-cleaning ceramic insulator 1; a storage groove 25 is formed on the bottom surface of the installation hoop 24. The storage groove 25 is in the shape of an arc-shaped groove. The top end of the elastic protective cover 28 is fixed on the top surface of the storage grooves 25 at the bottoms of the two installation hoops 24. The elastic protective cover 28 is in the shape of a circular tube cover. After the elastic protective cover 28 is removed from the self-cleaning ceramic insulator 1, the elastic protective cover 28 is stuffed into the storage grooves 25 of the two installation hoops 24.

[0043] In use, when the self-cleaning ceramic insulator 1 is in the state of idle storage or turnover transportation, first expand the tensioning elastic band loop 29, and pull the tensioning elastic band loop 29 and the elastic protective cover 28 to be sleeved on the self-cleaning ceramic insulator 1 from the top of the self-cleaning ceramic insulator 1, and sleeve the elastic band loop 29 on the bottom shaft body of the self-cleaning ceramic insulator 1. The elastic band loop 29 is fixed at the bottom end of the elastic protective cover 28; then tension two mounting hoops 24 to bypass the connecting handle 2, and buckle the two mounting hoops 24 on the top rod body of the self-cleaning ceramic insulator 1, and fix the two mounting hoops 24 together by means of bolts 27. At this time, the elastic protective cover 28 expands to protect the self-cleaning ceramic insulator 1 and reduce the hidden danger of dust adhesion; after tensioning the elastic band loop 29, turn up the elastic protective cover 28, cancel the tension of the elastic protective cover 28 towards the top of the self-cleaning ceramic insulator 1, and insert the elastic protective cover 28 into the storage groove 25 at the bottom of the two mounting hoops 24 to realize the storage of the elastic protective cover 28 when it is idle. When it is hot, the mounting hoops 24 can also be removed from the top end of the self-cleaning ceramic insulator 1.

[0044] The usage process of the self-cleaning extra-high voltage porcelain insulator is as follows:

[0045] Lean the cable against the cable trough 3, and the rubber gasket 5 provides additional protection. Press the cable bundling plate 4 against the cable to ensure that the screw 9 passes through the perforation 8 and extends into the side groove 7. Push and squeeze the rubber sealing piece 20 to deform and lift it, and extend the nut 10 into the side groove 7 and then sleeve and thread it on the screw 9. Tighten the nut 10 to tightly clamp the cable with the cable bundling plate 4. Dial the bottom end of the rubber sealing piece 20 to extend into the rubber baffle 21 to cover the through port 18. Install the connecting sleeve and the connecting ring: sleeve the connecting sleeve 15 on the top of the connecting handle 2 to ensure that the external thread 16 and the internal thread 17 correspond. Screw the connecting sleeve 15 to make it descend along the connecting handle 2, and at the same time the turntable 13 rotates in the limit groove 14. When the connecting sleeve 15 is completely screwed, ensure that the through port 18 and the side groove 7 correspond, and use the nut 10 to fix the screw 9 again. Install the rubber baffle and the elastic plastic strip: ensure that the rubber baffle 21 and the elastic plastic strip 23 are correctly installed to cover the unobstructed part of the side groove 7 and provide additional protection. Install the elastic protective cover (non-use state), prepare the elastic protective cover: if the self-cleaning ceramic insulator needs to be stored or transported, prepare the elastic protective cover 28 and the tensioning elastic band loop 29. Install the elastic protective cover: expand the tensioning elastic band loop 29 and sleeve the elastic protective cover 28 from the top of the self-cleaning ceramic insulator 1. Sleeve the elastic band loop 29 on the bottom shaft body of the self-cleaning ceramic insulator 1. Tension two mounting hoops 24 to bypass the connecting handle 2 and buckle them on the top rod body of the self-cleaning ceramic insulator 1. Use bolts 27 to fix the two mounting hoops 24 together. Dismantle the elastic protective cover: tension the tensioning elastic band loop 29 and turn up the elastic protective cover 28. Cancel the tension of the elastic protective cover 28 towards the top of the self-cleaning ceramic insulator 1. Insert the elastic protective cover 28 into the storage groove 25 at the bottom of the two mounting hoops 24. Dismantle the mounting hoops: if necessary, the mounting hoops 24 and the bolts 27 can be removed.
