Abstract
Description
Technical Field
[0001] This application relates to the field of reclosers, and in particular to a skirt structure for a recloser anti-salt spray pole. Background Technology
[0002] In special geographical environments such as coastal areas and saline-alkali zones, reclosers in power systems are exposed to salt spray for extended periods, facing severe challenges of corrosion and insulation degradation. As a key device in the distribution network for automatic fault isolation and power restoration, the insulation performance of the recloser's terminals directly affects the reliable operation of the equipment, and the terminal skirts are an important line of defense against salt spray corrosion and to ensure insulation.
[0003] However, with prolonged use, rainwater and salt spray will condense at the edges of the umbrella skirt and cannot slide off the surface in time. Rainwater and salt spray particles will corrode the umbrella skirt, thereby reducing the service life of the pole, seriously affecting the normal operation of the recloser, increasing equipment maintenance costs and the operational risks of the power system. Utility Model Content
[0004] To address the problem that rainwater and salt spray do not easily slide off the umbrella skirt surface and accumulate there, causing corrosion and affecting the normal operation of the recloser, this application provides an umbrella skirt structure for a recloser anti-salt spray pole.
[0005] The umbrella skirt structure of the recloser anti-salt spray pole provided in this application adopts the following technical solution:
[0006] A recontainer anti-salt spray pole skirt structure includes multiple small umbrella skirts and multiple large umbrella skirts installed on the outer wall of the pole skirt. The small umbrella skirts and large umbrella skirts are arranged alternately and fixed to the outer wall of the pole skirt with a gap. An anti-salt spray accumulation structure is provided on the outside of the pole skirt. The anti-salt spray accumulation structure includes a first arc-shaped water cut-out on the edge of the small umbrella skirt and a second arc-shaped water cut-out on the edge of the large umbrella skirt.
[0007] By adopting the above technical solution, the alternating arrangement of small and large umbrella skirts with spacing effectively increases the creepage distance between the skirts, thereby improving the overall insulation performance of the pole. Simultaneously, the first and second arc-shaped water-cutting nozzles effectively guide rainwater and salt spray particles to slide quickly off the umbrella skirt surface, preventing moisture accumulation at the edges and reducing corrosion.
[0008] Optionally, the small umbrella skirt includes a main body one and a main body two, the main body one is fixed on the main body two, the thickness of the small umbrella skirt is 10.7cm, the angle between the side wall of the small umbrella skirt and the bottom surface of the main body one is 13°, and the angle between the side wall of the small umbrella skirt and the bottom surface of the main body two is 14°.
[0009] By adopting the above technical solution, the thickness of the small umbrella skirt is 10.7cm, ensuring sufficient mechanical strength without excessively increasing weight. The sidewalls of the small umbrella skirt form a 13° angle with the bottom surface of the main body and a 14° angle with the bottom surface of the second main body. This helps guide rainwater and salt spray particles to slide off quickly, reducing their residence time on the surface of the small umbrella skirt and thus reducing the risk of corrosion.
[0010] Optionally, the large umbrella skirt includes a body three and a body four, with the body three fixed on the body four. The thickness of the large umbrella skirt is 12.6 cm, the angle between the side wall of the large umbrella skirt and the bottom surface of the body three is 12°, and the angle between the side wall of the large umbrella skirt and the bottom surface of the body four is 13°.
[0011] By adopting the above technical solution, the thickness of the large umbrella skirt is 12.6cm, ensuring sufficient mechanical strength without excessively increasing weight. The angle between the sidewall of the large umbrella skirt and the bottom surface of body three is 12°, and the angle with the bottom surface of body four is 13°. This helps guide rainwater and salt spray particles to slide off quickly, reducing their residence time on the surface of the large umbrella skirt, thereby reducing the risk of corrosion.
[0012] Optionally, both the small umbrella skirt and the large umbrella skirt are symmetrical about the central axis of the pole.
[0013] By adopting the above technical solution, the symmetrical arrangement of the small and large umbrella skirts about the central axis of the pole makes the distribution of the umbrella skirt structure on the pole more uniform. This helps to ensure that the umbrella skirt can evenly distribute the force when subjected to external environmental pressure, avoiding local stress concentration caused by structural asymmetry.
[0014] Optionally, both the outer walls of the small umbrella skirt and the outer walls of the large umbrella skirt are provided with a hydrophobic coating.
[0015] By adopting the above technical solution, the hydrophobic coating effectively promotes the rapid sliding of water, avoids the accumulation of salt spray particles on the umbrella skirt surface, and thus reduces the occurrence of corrosion.
[0016] Optionally, an input conductor is installed at the top of the pole, and an output conductor is installed in the middle of the pole.
[0017] By adopting the above technical solution, the input conductor is installed at the top of the pole and the output conductor is installed in the middle, enabling the recloser to realize the functions of interrupting fault current and conducting normal current in the power distribution network.
[0018] Optionally, a transparent observation window is installed on the pole.
[0019] By adopting the above technical solution, a transparent observation window is installed on the pole, which makes it easy to intuitively obtain the status of the arc-extinguishing chamber.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. The alternating arrangement of small and large umbrella skirts with water-cutting edges effectively guides rainwater and salt spray to slide quickly down the edges of the umbrella skirts, reducing the time that water stays on the surface of the umbrella skirts, thereby reducing the risk of corrosion and extending the service life of the pole.
[0022] 2. By applying a hydrophobic coating to the surfaces of the small and large umbrella skirts, the hydrophobic properties of the umbrella skirts are enhanced, the adhesion area of salt spray particles on the umbrella skirt surface is reduced, and the corrosion resistance of the pole is significantly improved in a salt spray environment.

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0029] This application discloses a skirt structure for a recloser anti-salt spray pole.
[0030] Reference Figure 1A skirt structure for a reconciler anti-salt spray pole includes multiple small skirts 1 and multiple large skirts 2, both of which are symmetrical about the central axis of the pole. The small skirts 1 and large skirts 2 are arranged alternately with a certain spacing and fixed to the outer wall of the pole. Additionally, an anti-salt spray accumulation structure 3 is provided on the outside of the pole.
[0031] By fixing the small umbrella skirt 1 and the large umbrella skirt 2 to the outer wall of the pole, not only can the surface distance be increased to extend the creepage path and improve the insulation performance, but also the pollutants such as rainwater, salt spray, and dust can be prevented from adhering to the pole, thus protecting the pole in harsh environments.
[0032] Reference Figure 1 A hydrophobic coating 4 is provided on the outer wall of both the small umbrella skirt 1 and the large umbrella skirt 2. The hydrophobic coating 4 has superhydrophobic properties, which allows rainwater, salt spray droplets, etc. to quickly roll off the surface of the umbrella skirt, preventing them from staying on the surface and further reducing the corrosive effect of rainwater on the umbrella skirt.
[0033] Reference Figure 1 An input conductor 5 is installed at the top of the pole, an output conductor 6 is installed in the middle of the pole, and an arc-extinguishing chamber is installed inside the pole.
[0034] By fixing the input conductor 5 and the output conductor 6 in layers on the pole post, mutual interference between the input and output lines can be avoided, electromagnetic induction losses can be reduced, and power transmission efficiency can be improved. By integrating an arc-extinguishing chamber inside the pole post, the pole post provides a stable and sealed operating environment for the arc-extinguishing chamber, reducing the erosion of the arc-extinguishing chamber by the external environment and improving the overall reliability and stability of the equipment.
[0035] Reference Figure 1 A transparent observation window 7 is fixed on the outer wall of the pole, and the arc-extinguishing chamber is located on the inner wall of the transparent observation window 7. The state of the arc-extinguishing chamber can be directly displayed to the observer through the transparent observation window 7. The observation window can project the state information inside the pole regardless of day or night, so that on-site personnel can verify and confirm it.
[0036] Reference Figure 2 The anti-salt spray accumulation structure 3 includes a first arc-shaped water inlet 31 and a second arc-shaped water inlet 32. The first arc-shaped water inlet 31 is located at the edge of the small umbrella skirt 1; the second arc-shaped water inlet 32 is located at the edge of the large umbrella skirt 2.
[0037] The curved water-cutting nozzle prevents rainwater or salt spray from condensing at the edges of the umbrella skirt, as the surface tension of the liquid cannot withstand its weight. Once the liquid accumulates to a sufficient volume, the water droplets can fall off naturally, thus preventing rainwater from accumulating on the umbrella skirt and reducing its corrosive effect.
[0038] Reference Figure 3The overall thickness of the small umbrella skirt 1 is 10.7cm, and the small umbrella skirt 1 includes a main body 11 and a main body 2 12, with the main body 11 fixed on the main body 2 12. The angle between the side wall of the small umbrella skirt 1 and the bottom surface of the main body 11 is 13°, and the angle between the side wall of the small umbrella skirt 1 and the bottom surface of the main body 2 12 is 14°.
[0039] Both body 11 and body 2 12 are made of corrosion-resistant materials, exhibiting excellent corrosion resistance. The surface of body 11 is polished to reduce the coefficient of friction. The thickness of the small umbrella skirt 1 is set at 10.7 cm, ensuring sufficient mechanical strength without excessively increasing weight. Furthermore, the sidewall of the small umbrella skirt 1 forms a 13° angle with the bottom surface of body 11 and a 14° angle with the bottom surface of body 2 12, and is complemented by a first arc-shaped water-cutting nozzle 31 located at the edge of the small umbrella skirt 1. This helps guide rainwater and salt spray particles to slide off quickly, reducing their residence time on the surface of the small umbrella skirt 1, thereby reducing the risk of corrosion.
[0040] Reference Figure 3 The overall thickness of the large umbrella skirt 2 is 12.6cm, and the large umbrella skirt 2 includes a main body 3 21 and a main body 4 22, with the main body 3 21 fixed to the main body 4 22. The angle between the side wall of the large umbrella skirt 2 and the bottom surface of the main body 3 21 is 12°, and the angle between the side wall of the large umbrella skirt 2 and the bottom surface of the main body 4 22 is 13°.
[0041] Both body 3 (21) and body 4 (22) are made of corrosion-resistant materials, exhibiting excellent corrosion resistance. Furthermore, the surface of body 3 (21) is polished to reduce the coefficient of friction. The thickness of the large umbrella skirt 2 is set at 12.6 cm, ensuring sufficient mechanical strength without excessively increasing weight. Additionally, the sidewalls of the large umbrella skirt 2 form a 13° angle with the bottom surface of body 1 (11) and a 14° angle with the bottom surface of body 2 (12), and are complemented by a second arc-shaped water-cutting nozzle 32 located at the edge of the large umbrella skirt 2. This helps guide rainwater and salt spray particles to slide off quickly, reducing their residence time on the surface of the large umbrella skirt 2, thereby reducing the risk of corrosion.
[0042] Reference Figure 3 The reason for casting Body 2 12 and Body 4 22 at the bottom of Body 1 11 and Body 3 21 respectively is to make the bottom of the small umbrella skirt 1 and the large umbrella skirt 2 convex. This allows rainwater to fall along the convex area, and rainwater is less likely to accumulate at the bottom of the umbrella skirt, thereby reducing the corrosion of the bottom of the umbrella skirt by rainwater.
[0043] The implementation principle of the umbrella skirt structure of the recloser anti-salt spray pole in this application embodiment is as follows: by opening a first arc-shaped water cut-out 31 at the edge of the small umbrella skirt 1 and at a specific angle of the small umbrella skirt 1, and in conjunction with the hydrophobic coating 4 on the surface of the small umbrella skirt 1, rainwater or salt spray cannot accumulate at the edge of the small umbrella skirt 1, reducing the corrosion of the small umbrella skirt 1 by rainwater; by opening a second arc-shaped water cut-out 32 at the edge of the large umbrella skirt 2 and at a specific angle of the large umbrella skirt 2, and in conjunction with the hydrophobic coating 4 on the surface of the large umbrella skirt 2, rainwater or salt spray cannot condense at the edge of the large umbrella skirt 2, and water droplets can fall off naturally, reducing the corrosion of the large umbrella skirt 2 by rainwater.
