Description

Technical Field

[0001] This utility model relates to the field of insulator technology, and in particular to a hydrophobic and anti-icing high-voltage porcelain insulator. Background Technology

[0002] In power transmission systems, high-voltage porcelain insulators are critical insulation components, and their performance directly affects the safety and stability of power transmission. However, under severe weather conditions, such as hail and freezing rain, high-voltage porcelain insulators face the risk of being damaged by hail or covered with ice. Surface ice not only increases the weight of the insulator, leading to increased mechanical stress, but may also trigger ice flashover, where the ice layer on the insulator surface breaks down under voltage, causing power outages. Furthermore, the ice layer may damage the surface structure of the insulator, reducing its insulation performance and thus threatening the safe operation of the entire power system. Although existing high-voltage porcelain insulators possess some waterproof and anti-icing capabilities, their protective effect under extreme weather conditions remains insufficient. Especially when hail directly impacts the insulator, traditional insulator structures often struggle to effectively withstand such impacts, leading to insulator damage and consequently affecting the reliability of power transmission. Therefore, developing a high-voltage porcelain insulator capable of withstanding hail impacts and effectively preventing surface ice accumulation is of great significance for improving the stability and safety of power systems. Utility Model Content

[0003] This invention provides a hydrophobic, anti-icing high-voltage porcelain insulator, which solves the problems in the background technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A hydrophobic and anti-icing high-voltage porcelain insulator includes a mounting rod, wherein an insulating tube is provided on the surface of the mounting rod, and an insulator body is mounted on the surface of the insulating tube. The insulating tube is fitted with a sleeve, and the sleeve is provided with first support rods at equal intervals in a ring on its surface. The other end of the first support rod is connected to a first support ring, and the surface of the first support ring is movably connected with a support strip. The sleeve has a second support rod equidistantly arranged in a ring on the lower side of its surface, and the other end of the second support rod is connected to a second support ring. The surface of the second support ring is movably connected to a connecting pipe, and the inside of the connecting pipe is movably connected to a connecting rod. The support bar has partitions on both sides, and the surface of the partitions has rotating rods that are connected to the connecting rods.

[0005] Preferably, the insulator body is umbrella-shaped, and the surface of the insulator body is coated with a superhydrophobic coating.

[0006] Preferably, the surface of the support strip is provided with a waterproof cloth.

[0007] Preferably, a spring is provided at the bottom of the inner part of the connecting tube, and a connecting plate connected to the connecting rod is connected to the top of the spring.

[0008] Preferably, the length of the connecting pipe is less than the distance between one end of the support bar and the surface of the insulator body.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, a first support rod and a second support rod are equidistantly arranged in a ring on the surface, connecting the first support ring and the second support ring respectively. Support strips and connecting pipes are connected to the surfaces of the first support ring and the second support ring. A waterproof cloth is provided on the surface of the support strips, and springs are provided inside the connecting pipes. This not only enhances the waterproof performance of the insulator and prevents rainwater from penetrating into the insulator, but also provides a certain buffer space for the connecting rods, support strips, and waterproof cloth when subjected to impact, thereby absorbing the impact energy of hail and protecting the insulator from damage.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] Reference Figures 1-3A hydrophobic, anti-icing high-voltage porcelain insulator includes a mounting rod 1, an insulating tube on the surface of the mounting rod 1, and an insulator body 2 mounted on the surface of the insulating tube; a sleeve 3 is mounted on the surface of the insulating tube, and first support rods 4 are equidistantly arranged in a ring on the surface of the sleeve 3, with the other end of the first support rods 4 connected to a first support ring 5, and a support strip 6 movably connected to the surface of the first support ring 5; second support rods 8 are equidistantly arranged in a ring on the lower side of the surface of the sleeve 3, with the other end of the second support rods 8 connected to a second support ring 9, and a connecting pipe 10 movably connected to the surface of the second support ring 9. Furthermore, a connecting rod 11 is movably connected inside the connecting pipe 10; partitions 12 are respectively provided on both sides of the support bar 6, and rotating rods 13 connected to the connecting rods 11 are provided on the surface of the partitions 12. This is to facilitate the waterproof cloth 7 to cover the insulator body 2 in severe weather, preventing rainwater from entering the interior of the insulator body 2. At the same time, if hail falls, the hail will come into contact with the waterproof cloth 7 or the support bar 6. When impacted, the connecting rods 11 and springs 14 can play a certain buffering role, thereby absorbing the impact energy of the hail and protecting the insulator from damage.

[0014] Furthermore, the insulator body 2 is umbrella-shaped, and the surface of the insulator body 2 is coated with a superhydrophobic coating. This coating has extremely low surface energy, which can effectively reduce the adhesion of water droplets on the surface of the insulator, thereby reducing the possibility of icing. The superhydrophobic coating also has a self-cleaning function, which can prevent dirt from accumulating on the surface of the insulator and maintain its good insulation performance.

[0015] Furthermore, a waterproof cloth 7 is provided on the surface of the support bar 6, which further enhances the waterproof performance of the insulator and prevents rainwater from penetrating into the interior of the insulator.

[0016] Furthermore, a spring 14 is provided at the bottom of the inner end of the connecting tube 10, and a connecting plate 15 connected to the top of the spring 14 is connected to the connecting rod 11. The spring 14 and the connecting plate 15 provided inside the connecting tube 10 provide a certain buffer space for the connecting rod 11 when it is impacted, thereby absorbing the impact energy of hail and protecting the insulator from damage.

[0017] Furthermore, the length of the connecting pipe 10 is less than the distance between one end of the support bar 6 and the surface of the insulator body 2. This is to prevent the hail from having too great an impact on the support bar 6, causing one end of the support bar 6 to collide with the insulator body 2 and be damaged.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
