Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a long-life ceramic insulator for high-voltage lines. Background Technology

[0002] Porcelain insulators are inorganic non-metallic insulating devices made from natural minerals such as clay, feldspar, and quartz, and fired at high temperatures. Their core function is to achieve electrical isolation in power transmission lines and equipment, that is, to withstand working voltage and overvoltage while ensuring that current does not flow into the ground or towers through the supporting structure, and to provide sufficient mechanical strength to support conductors and resist external loads such as wind, ice, and earthquakes. With its excellent weather resistance, aging resistance, and long-term stable insulation performance, it is widely used in suspension strings and tension strings of high-voltage AC or DC transmission lines, post insulators and busbar support insulators in substations, as well as in railway electrification contact networks, power plant outgoing line structures, and industrial power distribution equipment. It is one of the most traditional and still dominant insulating materials in the power system.

[0003] Porcelain insulators, which are widely used in high-voltage lines, will gradually lose their anti-flashover coating on the shed surface after long-term operation. Subsequently, dirt will easily accumulate on the surface of the insulator and become damp in humid weather, leading to a significant increase in leakage current. In severe cases, it can even cause local arcing, eventually inducing surface flashover, resulting in a sharp decline in insulation performance and even causing line tripping accidents, threatening the safe and stable operation of the power grid.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The long-life porcelain insulator for high-voltage lines disclosed in this invention is mainly used in scenarios where the anti-flashover coating of porcelain insulators ages, becomes contaminated and damp, leading to increased leakage current, which can easily cause local arcing and surface flashover, resulting in decreased insulation and tripping, threatening the safety of the power grid.

[0020] Reference Figures 1-5 A long-life porcelain insulator for high-voltage lines, comprising: The porcelain insulator body 6 has a mounting plate 5 at its lower end and a fixing ring seat 8 on its upper side. Driven gear ring 7 is connected to the outer wall of fixed ring seat 8 via a bearing; Rotating collar 2 is connected to the upper outer wall of the porcelain insulator body 6 via a bearing; The periodic coating component 3 is disposed on the outside of the porcelain insulator body 6, and includes two perforated guide rail plates 302. Auxiliary drive component 4 is mounted on mounting plate 5 and includes drive frame 401.

[0021] In this invention, the periodic coating component 3 further includes: Multiple coating inclined brackets 301 are equally spaced on one of the perforated guide rail plates 302. The multiple coating inclined brackets 301 can be fixed to one of the perforated guide rail plates 302 by bolts. Multiple cleaning inclined frames 303 are equally spaced on another perforated guide rail plate 302. The multiple cleaning inclined frames 303 can be fixed to the other perforated guide rail plate 302 by bolts.

[0022] In this invention, the periodic coating component 3 further includes: Multiple coating heads 306 are respectively disposed inside the corresponding coating inclined frame 301, and fixing frames 305 are respectively disposed on both sides of the multiple coating inclined frame 301; Multiple cleaning brushes 309 are respectively installed inside the corresponding cleaning brackets 303, and dust collection chambers 310 are respectively installed on both sides of the multiple cleaning brackets 303.

[0023] In this invention, the periodic coating component 3 further includes: Multiple anti-flashover coating cylinders 304 are respectively disposed inside the corresponding fixing frame 305. One end of the infusion tube 307 is disposed on the outer wall of each of the multiple anti-flashover coating cylinders 304. The other end of the infusion tube 307 is respectively inserted into the interior of the corresponding coating head 306. Multiple dust collection boxes 313 are respectively set on the corresponding cleaning inclined frame 303. One end of the conveying pipe 312 is inserted into each side of the multiple dust collection boxes 313, and the other end of the multiple conveying pipes 312 is inserted into the interior of the corresponding dust collection chamber 310.

[0024] In this invention, the periodic coating component 3 further includes: Multiple infusion pumps 308 are respectively installed on the outer wall of the corresponding infusion tube 307; Multiple vacuum pumps 311 are respectively installed on the outer wall of the corresponding delivery pipe 312.

[0025] Specifically, by activating the two telescopic rods 13, the corresponding movable plates 12 are moved. Since the two movable plates 12 are fixedly connected to the corresponding two support rods 11, the two sets of support rods 11 move in the same direction inside the corresponding mounting rings 9 during the movement of the two movable plates 12. Since the two perforated guide rail plates 302 are fixedly connected to the corresponding two sets of support rods 11 through the connecting plates 10 at both ends, the two perforated guide rail plates 302 also move in the same direction, thereby causing the multiple cleaning inclined frames 303 to move closer to the corresponding umbrella caps and the multiple coating inclined frames 301 to move away from the corresponding umbrella caps, until the cleaning brushes 309 on the multiple cleaning inclined frames 303 contact the corresponding umbrella caps. Subsequently, the multiple fan blades 1 drive the rotating collar 2 to rotate under the wind power, thereby allowing the periodic coating assembly 3 to revolve around the outside of the porcelain insulator body 6, thus cleaning the multiple umbrella caps with the cleaning brushes 309. The dust on the surface is cleaned to improve the coating effect of the anti-flashover coating. The cleaned dust is absorbed by multiple dust collection chambers 310. Then, multiple dust collection pumps 311 are turned on to transport the dust inside the multiple dust collection chambers 310 to the corresponding dust collection boxes 313 through the corresponding delivery pipes 312 for easy recycling and to prevent secondary pollution during cleaning. After the multiple umbrella caps are pre-cleaned, multiple movable telescopic rods 13 are turned on to retract, so that multiple cleaning slant frames 303 are away from multiple umbrella caps, while multiple coating slant frames 301 are close to multiple umbrella caps. Then, multiple infusion pumps 308 are turned on to transport the anti-flashover coating inside multiple anti-flashover coating cylinders 304 to the corresponding coating head 306 through multiple infusion pipes 307. Then, the multiple coating heads 306 revolve around the corresponding umbrella caps to apply the anti-flashover coating to the surface of the umbrella caps.

[0026] In specific application scenarios, the movable telescopic rod 13 pushes the movable plate 12, causing the fixed support rod 11 to move in the same direction within the mounting ring 9, thereby displacing the perforated guide rail plate 302 as a whole. This allows the cleaning inclined frame 303 and the coating inclined frame 301 to alternately move closer to or further away from the umbrella cap. This structure can quickly switch between the "pre-cleaning" and "coating" working states, ensuring orderly connection of processes and avoiding mutual interference. During the revolution, the cleaning brush 309 contacts the surface of the umbrella cap, efficiently removing accumulated dust; at the same time, the dust pump 311 promptly draws in dust through the dust collection chamber 310. Dust is generated and sent to the dust collection box 313 for centralized collection via the conveying pipe 312. This structure can significantly improve the adhesion of subsequent coatings and effectively prevent dust from flying during cleaning, thus achieving clean operation. After cleaning, the coating slant 301 is close to the umbrella cap, and the infusion pump 308 delivers the new coating in the anti-flashover coating cylinder 304 to the coating head 306 via the infusion pipe 307. During the revolution, it is evenly coated on the outer wall of the umbrella cap. The coating system has continuous material supply and uniform coating, which can ensure that every part of the umbrella cap surface is completely covered and effectively restore the anti-flashover performance.

[0027] Reference Figure 1, Figure 2 , Figure 6 and Figure 7 In a preferred embodiment, the auxiliary drive component 4 further includes: A hollow shaft 403 is disposed inside the drive frame 401. A drive gear 402 is disposed on the outer wall of the hollow shaft 403. The drive gear 402 meshes with the driven gear ring 7. The suspension plate 409 is located on the underside of the mounting plate 5.

[0028] In this invention, the auxiliary driving component 4 further includes: An inflation tube 407 is installed inside the suspension plate 409, with one end of the inflation tube 407 located inside the hollow shaft 403. Friction airbag 404 is disposed on the outer wall of one end of inflation tube 407, and the interior of friction airbag 404 is connected to the interior of inflation tube 407. The drive motor 406 is located on the lower side of the suspension plate 409, and the drive end of the drive motor 406 is connected to the other end of the inflation pipe 407 via a coupling.

[0029] In this invention, the auxiliary driving component 4 further includes: A sealing plate 405 is disposed inside the air inlet pipe 407, and an air supply pipe 410 is disposed inside the sealing plate 405. An air pump 408 is located on the lower side of the sealing plate 405, and the air pump 408 is connected to the air supply pipe 410 at its inflation end.

[0030] Specifically, by turning on the air pump 408, air is pumped into the air pipe 407 through the air supply pipe 410, causing the friction airbag 404 to expand and press against the inner wall of the hollow shaft 403. Under normal circumstances, the friction airbag 404 is in a contracted state, thus avoiding affecting the revolution state of the periodic coating component 3 when the wind provides driving force. Then, by turning on the drive motor 406, the air pipe 407 is rotated. Under the action of friction, the hollow shaft 403 drives the drive gear 402 to rotate. Since the drive gear 402 meshes with the driven gear ring 7, the driven gear ring 7 drives the periodic coating component 3 to revolve around the porcelain insulator body 6 while performing pre-cleaning and coating work.

[0031] In specific application scenarios, when wind power is insufficient, the air pump 408 inflates the air pipe 407 through the air supply pipe 410, causing the friction airbag 404 to expand and press against the inner wall of the hollow shaft 403. Subsequently, the drive motor 406 drives the air pipe 407 to rotate, and the torque is transmitted to the hollow shaft 403 through friction. Then, the drive gear 402 meshes with the driven gear ring 7 to drive the periodic coating component 3 to revolve. This electric auxiliary mechanism automatically intervenes when there is no wind to ensure the continuity of operation. The friction airbag 404 is normally contracted, without adding extra resistance and without affecting the free rotation when driven by wind power, thus taking into account both energy saving and reliability.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 In a preferred embodiment, it also includes: Two mounting rings 9 are respectively set on the upper side of the driven gear ring 7 and the lower side of the rotating collar 2. Two support rods 11 are slidably connected inside the two mounting rings 9. The two support rods 11 located on the same mounting ring 9 are respectively provided with the same connecting plate 10 at both ends. The two ends of the two perforated guide rail plates 302 are respectively fixedly connected to the two connecting plates 10 located on the same vertical line. Multiple fan blades 1 are disposed on the outer wall of the rotating collar 2.

[0033] In a preferred embodiment, it also includes: Two movable plates 12 are respectively disposed on the outer wall of the two corresponding support rods 11; Two telescopic rods 13 are respectively installed on the outer wall of the corresponding mounting ring 9, and the telescopic ends of the two telescopic rods 13 are respectively fixedly connected to the corresponding moving plate 12.

[0034] Working Principle: The anti-flashover coating on the surface of the sheds of the porcelain insulator body 6, widely used in high-voltage lines, gradually ages and fails after long-term operation. Therefore, a periodic coating assembly 3 periodically applies a new anti-flashover coating to the outer wall of the shed cap of the porcelain insulator body 6. In this process, two movable telescopic rods 13 are activated to push the corresponding movable plates 12, causing them to move. Since the two movable plates 12 are fixedly connected to the corresponding two support rods 11, the two sets of support rods 11 move in the same direction within the corresponding mounting rings 9 during the movement of the two movable plates 12. Because the two perforated guide rail plates 302 are fixedly connected to the corresponding two sets of support rods 11 through connecting plates 10 at both ends, the two perforated guide rail plates 302 also move in the same direction, causing multiple cleaning inclined frames 303 to approach the corresponding shed caps and multiple coating inclined frames 301 to move away from the corresponding shed caps, until the cleaning brushes 309 on the multiple cleaning inclined frames 303 contact the corresponding shed caps. Subsequently, multiple fan blades 1, driven by wind power, rotate the rotating collar 2, allowing the periodic coating assembly 3 to apply a new coating to the porcelain insulator body. The outermost ring rotates, thereby cleaning the dust on the surface of multiple umbrella caps using cleaning brush 309, improving the coating effect of the subsequent anti-fouling flashing paint. The cleaned dust is absorbed by multiple dust collection chambers 310, and then multiple dust pumps 311 are activated to transport the dust inside the multiple dust collection chambers 310 through the corresponding delivery pipes 312 to the corresponding dust collection boxes 313 for easy recycling and to prevent secondary pollution during cleaning. After the multiple umbrella caps are pre-cleaned, multiple movable telescopic rods 13 are activated again to retract, thereby allowing multiple... The inclined frame 303 is cleaned away from multiple umbrella caps, while multiple coating inclined frames 301 are close to multiple umbrella caps. Then, by turning on multiple infusion pumps 308, the anti-flashover coating inside multiple anti-flashover coating cylinders 304 is delivered into the corresponding coating head 306 through multiple infusion tubes 307. Then, while the multiple coating heads 306 revolve around the corresponding umbrella caps, they apply anti-flashover coating to the surface of the umbrella caps. In this way, by regularly applying anti-flashover coating to the porcelain insulator umbrella caps, the failure of the anti-flashover coating of the porcelain insulator umbrella caps after long-term operation is prevented. When the ambient wind force cannot provide the driving force for the periodic coating component 3 to revolve, the air pump 408 can be turned on to inflate the air pipe 407 through the air supply pipe 410, thereby causing the friction airbag 404 to expand and press against the inner wall of the hollow shaft 403. Under normal circumstances, the friction airbag 404 is in a contracted state, thus avoiding affecting the revolve state of the periodic coating component 3 when the wind provides the driving force. Then, the drive motor 406 is turned on to drive the air pipe 407 to rotate. Under the action of friction, the hollow shaft 403 drives the drive gear 402 to rotate. Since the drive gear 402 meshes with the driven gear ring 7, the driven gear ring 7 drives the periodic coating component 3 to revolve around the porcelain insulator body 6 while performing pre-cleaning and coating work.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
