Description

Technical Field

[0001] This application relates to the field of power equipment, and more particularly to a pollution-proof insulator. Background Technology

[0002] Insulators are widely used in national power grids at all levels. Their main function is to mechanically connect conductors and towers, while also providing electrical insulation. However, over long-term use, insulators (especially suspension porcelain insulators) accumulate dirt. If this dirt is not cleaned in time, it can lead to "flashover" accidents in the power grid, causing power outages and seriously affecting the normal operation of the power grid and the stability of power supply.

[0003] Among insulator contaminants, bird droppings are the most damaging. Bird droppings are corrosive; if they adhere to and erode the insulator surface, they further reduce the insulator's insulation performance, making flashover accidents more likely and even causing grid flashover, posing a threat to grid safety. This situation is particularly severe in outdoor areas, as birds like to build nests on power towers, and it's common to see large numbers of birds roosting and defecating on high-voltage lines.

[0004] Currently, the power industry commonly uses regular cleaning and applying anti-fouling coatings to address insulator fouling. However, these methods have some limitations: regular cleaning requires significant manpower and resources and is difficult to implement in certain geographical locations; while traditional anti-fouling coatings can reduce fouling to some extent, their protective effect against highly corrosive fouling such as bird droppings is limited. Furthermore, existing anti-fouling measures often neglect the impact of bird behavior and lack targeted bird deterrent designs.

[0005] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0006] The purpose of this application is to provide a pollution-resistant insulator that effectively prevents the adhesion and corrosion of various types of dirt (especially bird droppings), and achieves a bird-repelling effect through special surface treatment or pattern design, thereby comprehensively improving the pollution-resistant performance and service life of the insulator, reducing the occurrence of power grid flashover accidents, and improving the safety and reliability of the power grid.

[0007] According to one aspect of this application, a pollution-resistant insulator is provided. The pollution-resistant insulator includes an insulator body, a functional layer, and a patterned layer. The insulator body includes an upper surface region and a lower surface region, wherein the upper surface region includes a first patterned region and a second patterned region. The functional layer at least covers the second patterned region. The patterned layer at least covers the first patterned region, such that the first patterned region and the second patterned region are visually distinguishable.

[0008] In some embodiments of this application, the functional layer covers the upper surface area, and the functional layer is a transparent layer located on the pattern layer. In other embodiments of this application, the functional layer covers the upper surface area, and the pattern layer is located on the functional layer.

[0009] In some embodiments of this application, at least one of the patterned layer and the functional layer comprises a fluorosilicone-based material, a solution gel material, or a nano-hydrophilic material.

[0010] In some embodiments of this application, the patterned layer is formed by sintering pigments coated on the insulator body or patterned stickers attached to the insulator body together with the insulator body.

[0011] In some embodiments of this application, the pattern layer and the functional layer comprise different materials.

[0012] In some embodiments of this application, the pattern layer is used to present bird-repelling patterns.

[0013] In some embodiments of this application, the anti-pollution insulator is a suspension insulator.

[0014] In some embodiments of this application, the anti-pollution insulator is a porcelain insulator.

[0015] The technical solution of this application effectively prevents the adhesion and corrosion of various types of dirt (especially bird droppings) by forming functional layers and patterned layers in different areas of the insulator surface. At the same time, the special pattern design has a bird-repelling effect. From two perspectives, it more comprehensively and effectively suppresses the possibility of flashover caused by birds, comprehensively improves the service life and anti-pollution performance of the insulator, and improves the safety and reliability of the power grid.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that throughout the accompanying drawings, the same elements are represented by the same or similar reference numerals. In the following description, some specific embodiments are used for descriptive purposes only and should not be construed as limiting this application in any way, but are merely examples of embodiments of this application. Conventional structures or constructions will be omitted where they may cause confusion in understanding this application.

[0019] As mentioned above, bird droppings are corrosive. If they adhere to and erode the surface of insulators, they will severely impact the insulation performance of the insulators, increasing the probability of flashover accidents and creating hidden dangers. This situation is particularly serious on high-voltage transmission lines in remote areas. For example, on high-voltage transmission lines in mountainous areas rich in bird resources, insulator strings typically consist of 20-30 suspension porcelain insulators. During spring and autumn bird migrations, large numbers of birds will briefly stop on the transmission lines, causing at least some insulator surfaces to quickly accumulate large amounts of bird droppings. This corrosive droppings also absorb dust and moisture from the air, forming potential conductive channels. Over time, the dirt layer on the insulator surface gradually thickens, and the soluble salts in it dissolve in the humid environment, forming an electrolyte solution with a certain degree of conductivity. In this case, the surface resistance of the insulator drops sharply, and the leakage current increases significantly. When the leakage current reaches a certain level, it will trigger flashover discharge, ultimately leading to a flashover accident. Therefore, if the problem of dirt on the insulator surface is not effectively solved, it will have a serious impact on the entire power transmission system.

[0020] There are two common approaches to addressing this issue in existing technologies: one approach is to coat the insulator surface with a comprehensive anti-fouling coating. This method can effectively prevent dirt from adhering by relying on the properties of the coating. However, this approach is costly and only addresses the symptoms, not the root cause, and cannot suppress the source of dirt. The other approach is to use mechanical cleaning equipment and manually climb to clean the insulator surface regularly. This approach has more drawbacks, including significantly increased labor costs, safety hazards, and difficulty in implementation in certain geographical locations.

[0021] The inventors of this application summarized the drawbacks of existing technologies and proposed an innovative solution: by forming functional layers and patterned layers in different areas of the insulator surface, and by applying a special pattern design, the possibility of bird-induced flashover is suppressed more comprehensively and effectively from two perspectives, thereby comprehensively improving the service life and anti-pollution performance of the insulator and enhancing the safety and reliability of the power grid.

[0022] The following detailed description of embodiments of this application uses a suspension disc insulator as an example, but those skilled in the art will understand that the scope of protection of this application is not limited thereto. For a bird in flight, any insulator of any shape or structure has an upper surface area visible from above and a lower surface area that is not easily seen. Specific coating settings for these areas can achieve the technical solutions of this application.

[0023] Figure 1a and Figure 1b Side and top views of an anti-pollution insulator 100 according to one embodiment of this application are shown respectively.

[0024] As shown in the figure, the anti-pollution insulator 100 is a suspension disc insulator, which includes an insulator body 110, a pattern layer 120 and a functional layer 130.

[0025] The insulator body refers to the main structure that provides mechanical support and electrical insulation, and can be made of porcelain, glass, or composite materials. In a preferred embodiment of this patent, the insulator body is a porcelain structure, that is, the anti-pollution insulator 100 can be a porcelain insulator.

[0026] At least one of the pattern layer 120 and the functional layer 130 is a material layer with anti-fouling function that can be applied to the insulator body by means of coating or the like. In some embodiments, at least one of the pattern layer 120 and the functional layer 130 may be a fluorosilicone-based material, a solution gel material, or a nano-hydrophilic material.

[0027] The selection of antifouling materials can be used to achieve different desired functions. For example, using fluorosilicone-based materials can provide good hydrophobicity and low surface energy, helping to prevent the adhesion of moisture and dirt. Specifically, copolymers of fluorinated acrylates and silicone-modified acrylates can be used as the main components. As another example, using nano-hydrophilic materials can allow moisture (such as rainwater) on the insulator surface to form a water film, isolating dirt from direct contact with the insulator surface.

[0028] The selection of these materials needs to be optimized based on the specific application environment and requirements (such as average environmental precipitation). For example, fluorosilicone-based materials may be preferred in arid regions; hydrophilic nanomaterials may be more suitable in rainy regions; and dense protective films formed by solution gel materials may be more advantageous in areas with severe industrial pollution.

[0029] The insulator body 110 includes an upper surface area and a lower surface area. The upper surface area refers to the surface area of ​​the insulator that is visible to birds flying overhead during operation and where bird droppings may adhere from top to bottom. Figure 1a and Figure 1b The areas shown are the upper surface areas of the disc suspension insulator. The lower surface area refers to the area of ​​the insulator that is not visible to birds flying overhead during operation and where bird droppings cannot adhere from top to bottom. Figure 1a and Figure 1b The lower surface region is not shown.

[0030] Further, the upper surface region includes a first patterned region and a second patterned region. In some embodiments, such as Figure 1a and 1b In the middle, the first pattern area and the second pattern area can be combined to form the entire upper surface area (therefore, Figure 1a and 1b (The first and second pattern areas cannot be labeled after 120 and 130 below). In some embodiments, the upper surface area includes other areas in addition to the first and second pattern areas.

[0031] The pattern layer 120 is arranged to at least cover the first pattern area. After the pattern layer 120 covers the first pattern area, the first pattern area and the second pattern area are visually distinguishable, that is, the upper surface area presents a visually recognizable pattern.

[0032] In some embodiments, the pattern layer 120 may be, for example, a coating applied only to the first pattern area, and the first pattern area and the second pattern area may be visually distinguishable by the color, texture and other characteristics of the pattern layer 120 itself.

[0033] In other embodiments, the pattern layer 120 may be, for example, a sticker, with the patterned portion of the sticker corresponding to a first patterned area and the blank transparent portion (i.e., the non-patterned portion) of the sticker corresponding to a second patterned area. The difference in the presentation of these two portions makes the first patterned area and the second patterned area visually distinguishable.

[0034] It is understandable that the visual distinguishability described above can be determined entirely by factors such as the color, texture, or shape of the first pattern area, or by a combination of factors such as the color, texture, or shape of the first and second pattern areas.

[0035] In some embodiments of this application, the pattern layer is used to present bird-repelling patterns. That is, based on the fact that the first pattern area and the second pattern area can be visually distinguished due to the arrangement of the pattern layer 120, the upper surface area, in whole or in part, presents a pattern that can be identified by birds as a predator or danger, such as eagle's spectacles, flames, concentric circles, etc.

[0036] exist Figure 1a and Figure 1b In this process, the anti-pollution insulator 100 also includes a functional layer 130. The functional layer 130 at least covers the second pattern area.

[0037] In some embodiments, the functional layer 130 may be a transparent layer covering the entire upper surface area, and the functional layer 130 is situated above the pattern layer 120. In these embodiments, an antifouling material may be used to form the functional layer 130, while the pattern layer 120 may be formed by sintering pigments coated on the insulator body 110 or patterned stickers attached thereto with the insulator body 110. The functional layer 130 serves to prevent fouling and, on the other hand, acts as a protective layer for the pattern layer 120.

[0038] In other embodiments, the functional layer 130 may cover the entire upper surface area and serve as a base layer beneath the pattern layer 120. In this case, two coatings are provided within the first pattern area, allowing for a more optimized effect through the combination of the two coatings within the same area.

[0039] For example, the functional layer 130 uses a solution gel material to cover the entire upper surface area. The protective film formed by the solution gel material has a porosity of less than 5%, forming a dense protective film on the entire surface and enhancing the anti-fouling ability. The pattern layer 120 uses a fluorosilicone-based material with a contact angle greater than 150°, forming a hydrophobic surface in the first pattern area and reducing dirt adhesion.

[0040] In other preferred embodiments of this application, the functional layer 130 can be disposed on the same layer as the pattern layer 120, respectively covering the second pattern area and the first pattern area. Of course, in this case, the functional layer 130 and the pattern layer 120 can also be made of different materials, such as fluorosilicone-based materials, solution gel materials, or nano-hydrophilic materials, to achieve different effects. For example, the functional layer 130 can be made of a material with certain anti-fouling capabilities but lower cost, such as ordinary fluorosilicone-based materials, providing good hydrophobicity and low surface energy in the second pattern area at a lower cost, inhibiting the adhesion of moisture and dirt; the pattern layer 120 can be made of a material with stronger anti-fouling capabilities, such as high-performance nano-hydrophilic materials, allowing moisture on the insulator surface to form a water film in the first pattern area at a slightly increased cost, making it difficult for dirt to directly contact the insulator surface. Thus, compared with the prior art, better anti-fouling capabilities are achieved while controlling the overall cost, and the combined pattern of the two areas achieves the effect of reducing bird droppings sources as described above. Furthermore, the different properties of the two coatings result in significant differences in the physical or chemical properties of adjacent areas, which helps the overall removal of bird droppings and other dirt.

[0041] In other embodiments of this application, the functional layer 130 can be used to achieve other functions. For example, the functional layer 130 can be made of a material that can be used for de-icing in winter. Thus, by combining the functional layer 130 with the pattern layer 120, not only can it repel birds and prevent dirt, but it can also achieve another additional function, namely, reducing the icing phenomenon on the surface of the insulator in winter (especially in cold regions) when birds are not active.

[0042] Compared with existing technologies, the anti-pollution insulator of this application significantly improves the anti-pollution and bird-repelling capabilities of the insulator through innovative pattern layer and functional layer design and pattern area layout, based on traditional insulators, and better solves practical problems in power grid operation.

[0043] In addition to the above embodiments, this application may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this application.
