Description

A high-voltage power grid surge arrester that is easy to disassemble and install. Technical Field

[0001] This application relates to the field of high-voltage power grid lightning protection technology, specifically to a high-voltage power grid lightning arrester that is easy to disassemble and install. Background Technology

[0002] With the continuous development and improvement of power systems, the safe and stable operation of high-voltage transmission lines has become a crucial aspect of these systems. In high-voltage transmission lines, surge arresters, as vital devices protecting electrical equipment from lightning overvoltage damage, directly impact the safety and reliability of the entire power system. However, traditional surge arresters suffer from complex installation and inconvenient maintenance, especially in remote areas or harsh environments where these problems are more pronounced.

[0003] In recent years, to improve the installation efficiency and maintenance convenience of surge arresters, the industry has begun to research and develop surge arresters with new structures. Among them, high-voltage power grid surge arresters that are easy to disassemble and install have attracted widespread attention because they can significantly reduce installation time and costs while improving subsequent maintenance efficiency. These surge arresters typically adopt a modular design, and through optimized connection methods (such as quick connectors, plug-in interfaces, etc.), the surge arresters can be quickly replaced or repaired without power interruption, greatly facilitating the work of on-site operators.

[0004] However, when repairing or replacing this type of surge arrester, manual climbing onto the high-voltage power grid frame is still required, which carries certain risks. For example, Chinese patent application CN202410265152.8 discloses a high-voltage power grid surge arrester that is easy to disassemble and install. Although it uses a fixing post, with the upper end of the fixing post connected to the upper end seat threadedly to the upper end of the high-voltage surge arrester body and the lower end of the fixing post connected to the lower end seat threadedly to the lower end of the high-voltage surge arrester body, which facilitates the installation of the high-voltage surge arrester body through the above-mentioned components, making it easy to install and fix the high-voltage surge arrester body, it still requires workers to climb onto the high-voltage power grid frame to operate, and the risks still exist.

[0005] Therefore, a high-voltage power grid surge arrester that is easy to disassemble and install is needed to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problem—specifically, to resolve the inherent risks associated with manually climbing onto the high-voltage power grid frame during surge arrester replacement—this application provides a high-voltage power grid surge arrester that is easy to disassemble and install.

[0007] A high-voltage power grid surge arrester that is easy to disassemble and install includes a base, a support mechanism on the base, and a connecting mechanism on the upper side of the base. The surge arrester is disposed between the support mechanism and the connecting mechanism. The connecting mechanism includes a downward-opening connecting cylinder, a connecting wire electrically connected to the top of the connecting cylinder, a lifting member disposed in the connecting cylinder, and a fixing plate fixedly connected to the inner top wall of the connecting cylinder. A motor is fixedly connected to the fixing plate, a winding wheel is fixedly connected to the output end of the motor, a pull rope is wound on the winding wheel, one end of the pull rope is fixedly connected to the winding wheel, and the other end of the pull rope is detachably connected to the top of the surge arrester. Two contact plates are fixedly connected to the top of the surge arrester, and the contact plates can abut against the inner top wall of the connecting cylinder.

[0008] Specifically, in the initial state, the top of the surge arrester is inserted into the connecting cylinder, the support mechanism supports the bottom of the surge arrester, and the two contact plates are in contact with the inner top wall of the connecting cylinder. When the surge arrester needs to be replaced, the support mechanism is moved away from the underside of the surge arrester. Then, the motor is started, and the motor's output end rotates, driving the winding wheel to rotate and releasing the pull rope on the winding wheel. The surge arrester then moves downwards under its own weight, and the contact plates break contact with the inner top wall of the connecting cylinder. The motor then continues to rotate, continuously releasing the pull rope... Release the tension cable, allowing the surge arrester to move downwards continuously. When the surge arrester reaches the ground, the operator removes it from the cable and installs a new surge arrester on the cable, along with new contact plates on the top of the new surge arrester. Then, the motor is restarted, and its output drives the winding wheel to rotate, winding the cable and lifting the new surge arrester. When the top of the surge arrester re-enters the connecting cylinder and the contact plates contact the inner top wall of the connecting cylinder, the motor is stopped. The support mechanism is then moved to support the bottom of the new surge arrester again.

[0009] The connection and support mechanisms enable the surge arrester to be supported and connected, allowing it to be installed on the high-voltage power grid frame. The lifting mechanism allows the surge arrester to be raised and lowered via the rotation of the winding wheel, facilitating replacement and eliminating the need for operators to climb the high-voltage power grid frame, thus reducing operational risks. Furthermore, the contact plates ensure electrical connection between the surge arrester and the connection mechanism, facilitating its normal operation.

[0010] Preferably, the support mechanism includes two slidably disposed support rods, the bottom end of the surge arrester is located between the two support rods, a fixed plate is fixedly sleeved on the bottom end of the surge arrester, a sliding plate is loosely sleeved on the bottom end of the surge arrester, the sliding plate is located below the fixed plate, a first spring is connected between the sliding plate and the fixed plate, the two support rods are disposed below the sliding plate, the support rods are in contact with the lower surface of the sliding plate, and the contact piece is made of elastic material.

[0011] Specifically, when the surge arrester is brought into contact, the support rod contacts the lower side of the sliding plate and simultaneously contacts the lower end of the surge arrester, clamping the lower end of the surge arrester. When the lifting component lowers the surge arrester, the two support rods first slide, moving away from the lower side of the sliding plate, allowing the surge arrester to descend through the gap between the two support rods. When the lifting component raises the surge arrester, the surge arrester is raised through the gap between the two support rods. After the surge arrester enters the connecting cylinder, the two support rods move towards each other, moving to the lower side of the sliding plate to support the sliding plate, thereby supporting the surge arrester.

[0012] The support rod, together with the sliding plate, the first spring, and the fixed plate, supports the surge arrester. The support rod can move and, together with the lifting component, raises and lowers the surge arrester. The first spring reduces the vibration of the high-voltage grid structure transmitted to the surge arrester, making the surge arrester more stable and extending its service life.

[0013] Preferably, the support rod is connected to the movable component, the movable component includes two symmetrically arranged first electromagnetic slide rails, and the two ends of the support rod are respectively fixedly connected to first electromagnetic sliders. The two first electromagnetic sliders are respectively slidably connected in the two first electromagnetic slide rails, and the first electromagnetic slide rails are fixedly connected to the base.

[0014] Specifically, when the support rod needs to be moved, the first electromagnetic slider is activated. The first electromagnetic slider slides in the first electromagnetic rail, and the first electromagnetic slider drives the support rod to move.

[0015] The movable component allows the support rod to move, facilitating the support of the surge arrester and enabling the surge arrester to be raised and lowered within the gap between the two support rods.

[0016] Furthermore, the first electromagnetic slide rail and the first electromagnetic slider are existing technologies and will not be described in detail here.

[0018] Specifically, when the two support rods move toward each other, the two support rods drive the first limiting rod and the second limiting rod to move toward each other. When the support rods contact the bottom side of the surge arrester, the ends of the two first limiting rods abut together, and the ends of the two second limiting rods abut together. The first limiting rods and the second limiting rods cooperate with the support rods to restrict the bottom of the surge arrester.

[0019] By setting up limiting components, the bottom end of the surge arrester can be clamped and limited in conjunction with the support rod, preventing the bottom end of the surge arrester from swinging and making the installation of the surge arrester more stable.

[0020] Preferably, the base includes two mounting rods, the first electromagnetic slide rail is fixedly connected between the two mounting rods, each mounting rod is fixedly connected to a mounting plate, the top of the mounting plate is fixedly connected to a connecting shaft, and the connecting shaft is rotatably connected to the connecting cylinder.

[0036] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0037] As shown in Figures 1, 4, 5, and 10, this application discloses a high-voltage power grid surge arrester that is easy to disassemble and install. It includes a base 1, a support mechanism 2 on the base 1, and a connecting mechanism 3 on the upper side of the base 1. The surge arrester 4 is disposed between the support mechanism 2 and the connecting mechanism 3. The connecting mechanism 3 includes a downward-opening connecting cylinder 31, with a connecting wire 32 electrically connected to the top of the connecting cylinder 31. A lifting member 33 is disposed within the connecting cylinder 31, and the lifting member 33 includes components fixedly connected to the base 1. The connecting cylinder 31 has a fixed plate 331 on its inner top wall. A motor 332 is fixedly connected to the fixed plate 331. A winding wheel 333 is fixedly connected to the output end of the motor 332. A pull rope 334 is wound on the winding wheel 333. One end of the pull rope 334 is fixedly connected to the winding wheel 333. The other end of the pull rope 334 is detachably connected to the top of the surge arrester 4. Two contact pieces 34 are fixedly connected to the top of the surge arrester 4. The contact pieces 34 can abut against the inner top wall of the connecting cylinder 31.

[0038] Specifically, in the initial state, the top of the surge arrester 4 is inserted into the connecting cylinder 31, the support mechanism 2 supports the bottom of the surge arrester 4, and the two contact pieces 34 are in contact with the inner top wall of the connecting cylinder 31. When the surge arrester 4 needs to be replaced, the support mechanism 2 is moved away from the underside of the surge arrester 4. Then, the motor 332 is started, and the output end of the motor 332 rotates, driving the winding wheel 333 to rotate, releasing the pull rope 334 on the winding wheel 333. Then, the surge arrester 4 moves downward under its own weight, and at the same time, the contact pieces 34 lose contact with the inner top wall of the connecting cylinder 31. After that, the motor 332 continues to rotate, releasing the pull rope 334. 4. The bolt arrester 4 is continuously released, causing it to move downwards. When the bolt arrester reaches the ground, the operator removes the bolt arrester 4 from the pull rope 334, then installs the new bolt arrester 4 on the pull rope 334 and installs the new contact piece 34 on the top of the new bolt arrester 4. Then, the motor 332 is started again, and the output end of the motor 332 drives the winding wheel 333 to rotate, winding the pull rope 334, thereby lifting the new bolt arrester 4. When the top of the bolt arrester 4 enters the connecting cylinder 31 again and the contact piece 34 contacts the inner top wall of the connecting cylinder 31, the motor 332 is stopped. Then, the support mechanism 2 is moved to support the bottom of the new bolt arrester 4 again.

[0039] The connection mechanism 3 and the support mechanism 2 are used to support and connect the surge arrester 4, allowing it to be installed on the high-voltage power grid frame. The lifting member 33 allows the surge arrester 4 to be raised and lowered by the rotation of the winding wheel 333, making it convenient for users to replace the surge arrester 4. This avoids the inconvenience of operators climbing onto the high-voltage power grid frame when replacing the surge arrester, reducing the work risk for operators. Furthermore, the contact piece 34 enables an electrical connection between the surge arrester 4 and the connection mechanism 3, facilitating the normal operation of the surge arrester 4.

[0040] As shown in Figures 2, 3, and 4, the support mechanism 2 includes two slidably mounted support rods 21. The bottom end of the surge arrester 4 is located between the two support rods 21. A fixed plate 22 is fixedly fitted onto the bottom end of the surge arrester 4. A sliding plate 23 is fitted onto the bottom end of the surge arrester 4 with a gap. The sliding plate 23 is located below the fixed plate 22. A first spring 24 connects the sliding plate 23 and the fixed plate 22. The two support rods 21 are located below the sliding plate 23. The support rods 21 are in contact with the lower side of the sliding plate 23. The contact piece 34 is made of an elastic material.

[0041] Specifically, when the surge arrester 4 is brought into contact, the support rod 21 contacts the lower side of the sliding plate 23, and simultaneously contacts the lower end of the surge arrester 4, clamping the lower end of the surge arrester 4. When the surge arrester 4 is lowered by the lifting member 33, the two support rods 21 are first slid away from the lower side of the sliding plate 23, allowing the surge arrester 4 to descend through the gap between the two support rods 21. When the surge arrester 4 is raised by the lifting member 33, the surge arrester 4 is raised through the gap between the two support rods 21. After the surge arrester 4 enters the connecting cylinder 31, the two support rods 21 move towards each other, moving to the lower side of the sliding plate 23 to support the sliding plate 23, thereby supporting the surge arrester 4.

[0042] The support rod 21, together with the sliding plate 23, the first spring 24, and the fixed plate 22, can support the surge arrester 4. The support rod 21 can move and, together with the lifting member 33, can raise and lower the surge arrester. The first spring 24 can reduce the vibration of the high-voltage grid frame transmitted to the surge arrester 4, making the surge arrester 4 more stable and improving its service life.

[0043] As shown in Figures 2, 7, and 8, the support rod 21 is connected to the movable component 25. The movable component 25 includes two symmetrically arranged first electromagnetic slide rails 251. The two ends of the support rod 21 are respectively fixedly connected to first electromagnetic sliders 252. The two first electromagnetic sliders 252 are slidably connected in the two first electromagnetic slide rails 251. The first electromagnetic slide rails 251 are fixedly connected to the base 1.

[0044] Specifically, when the support rod 21 needs to be moved, the first electromagnetic slider 252 is activated. The first electromagnetic slider 252 slides in the first electromagnetic rail 251, and the first electromagnetic slider 252 drives the support rod 21 to move.

[0045] The movable part 25 can move the support rod 21 to facilitate the support of the surge arrester 4 and allow the surge arrester 4 to be raised and lowered in the gap between the two support rods 21.

[0046] Furthermore, the first electromagnetic slide rail 251 and the first electromagnetic slider 252 are existing technologies and will not be described in detail here.

[0047] As shown in Figures 2, 8, and 9, each of the support rods 21 is provided with a limiting member 26. The limiting member 26 includes a first limiting rod 261 and a second limiting rod 262 that are slidably connected to the support rod 21. The ends of the two first limiting rods 261 on the two support rods 21 can abut each other, and the ends of the two second limiting rods 262 on the two support rods 21 can abut each other. The bottom end of the surge arrester 4 is located between the first limiting rod 261 and the second limiting rod 262.

[0048] Specifically, when the two support rods 21 move toward each other, the two support rods 21 drive the first limiting rod 261 and the second limiting rod 262 to move toward each other. When the support rod 21 contacts the bottom side of the surge arrester 4, the ends of the two first limiting rods 261 abut, and the ends of the two second limiting rods 262 abut. The first limiting rods 261 and the second limiting rods 262 cooperate with the support rod 21 to limit the bottom of the surge arrester 4.

[0049] By setting the limiting component 26, it can work with the support rod 21 to limit and clamp the bottom end of the surge arrester 4, preventing the bottom end of the surge arrester 4 from swinging, thus making the installation of the surge arrester 4 more stable.

[0050] As shown in Figure 7, the base 1 includes two mounting rods 11. The first electromagnetic slide rail 251 is fixedly connected between the two mounting rods 11. Each mounting rod 11 is fixedly connected to a mounting plate 12. The top end of the mounting plate 12 is fixedly connected to a connecting shaft 13. The connecting shaft 13 is rotatably connected to the connecting cylinder 31.

[0051] As shown in Figures 4, 8, and 9, the first limiting rod 261 is connected to a moving component 27. The moving component 27 includes a mounting groove 271 formed on the support rod 21. A second electromagnetic slide rail 272 is fixedly connected to the mounting groove 271. A second electromagnetic slider 273 is slidably connected to the second electromagnetic slide rail 272. The second electromagnetic slider 273 is fixedly connected to the first limiting rod 261. The second limiting rod 262 is connected to a sliding component 28. The sliding component 28 includes a sliding groove 281 formed in the support rod 21. A slider 282 is slidably connected to the sliding groove 281. The slider 282 is fixedly connected to the second limiting rod 262. A second spring 283 is connected between the slider 282 and the sliding groove 281.

[0052] Specifically, in use, when there is snow on the surge arrester 4, the second electromagnetic slider 273 is activated. The second electromagnetic slider 273 slides in the second electromagnetic rail 272, and the second electromagnetic slider 273 drives the first limiting rod 261 to move. The first limiting rod 261 pushes the bottom of the surge arrester 4 to move. At the same time, the bottom of the surge arrester 4 drives the second limiting rod 262 to move. The second limiting rod 262 drives the slider 282 to move. The slider 282 compresses the second spring 283. At the same time, the top of the surge arrester 4 drives the connecting cylinder 31 to tilt, and the connecting cylinder 31 rotates relative to the connecting shaft 13, causing the surge arrester 4 to tilt and the snow on it to fall off. Then, the second electromagnetic slider 273 is moved to reset the second electromagnetic slider 273. The second electromagnetic slider 273 drives the first limiting rod 261 to reset, and the slider 282 resets under the action of the second spring 283, thereby resetting the surge arrester 4.

[0053] By setting the moving part 27, the first limiting rod 261 can be moved, which drives the bottom end of the surge arrester 4 to move. At the same time, the rotational connection between the connecting cylinder 31 and the connecting shaft 13 causes the surge arrester 4 to tilt, allowing the snow on the surge arrester 4 to fall off, thus avoiding the impact of the snow on the normal operation of the surge arrester 4.

[0054] Furthermore, the second electromagnetic slide rail 272 and the second electromagnetic slider 273 are existing technologies and will not be described in detail here.

[0055] As shown in Figures 2 and 4, a retaining member 29 is provided at the bottom of the surge arrester 4. The retaining member 29 includes a magnetic disk 291 fixedly sleeved on the bottom of the surge arrester 4. An electromagnet 292 is fixedly connected to the bottom end of the first electromagnetic slide rail 251 near the second limiting rod 262. The electromagnet 292 can be magnetically attracted to the magnetic disk 291. The lower side of the magnetic disk 291 near the electromagnet 292 is a slope.

[0056] Specifically, during use, when the first limiting rod 261 pushes the bottom of the surge arrester 4 to move, when the magnetic disk 291 contacts the electromagnet 292, the electromagnet 292 is activated, and the electromagnet 292 attracts the electromagnet 292. Then, the second electromagnetic slider 273 is reset. After the second electromagnetic slider 273 is reset, the electromagnet 292 is stopped. Under the elastic force of the second spring 283, the second limiting rod 262 pushes the bottom of the surge arrester 4 to reset. At the same time, the surge arrester 4 impacts the first limiting rod 261 during reset, causing the snow on the surge arrester 4 to fall off.

[0057] By setting the retaining member 29, after the surge arrester 4 is tilted, the electromagnet 292 and the magnetic disk 291 attract the surge arrester 4 to maintain the tilt. After the first limiting rod 261 is reset, the second limiting rod 262 pushes the surge arrester 4 to reset, so that the surge arrester 4 collides with the first limiting rod 261, causing the surge arrester 4 to vibrate, which facilitates the shaking off of the snow on it.

[0058] Furthermore, the electromagnet 292 is existing technology and will not be described in detail.

[0059] As shown in Figure 7, a processing mechanism 5 is provided on the mounting plate 12. The processing mechanism 5 includes an air box 51 fixedly connected to the mounting plate 12. The air box 51 has multiple air holes at equal intervals from top to bottom on the side near the surge arrester 4. Each air hole is connected to an air nozzle 52. The air box 51 is connected to an air source component 53.

[0060] Specifically, when there is snow on the surge arrester 4, the air source component 53 is activated, and the air source component 53 supplies air to the air box 51. The air is blown onto the surge arrester 4 through the air nozzle 52, blowing the snow off the surge arrester 4.

[0061] Furthermore, the mounting plate 12 has an embedding groove, and the air box 51 is fixedly connected in the embedding groove.

[0062] As shown in Figure 8, the air source component 53 includes an airbag 531 disposed between the support rod 21 and the mounting rod 11. The airbag 531 is provided with a one-way air inlet. A third spring 532 is connected between the two ends of the airbag 531. An air pipe 533 is connected to the airbag 531 and is connected to the air box 51.

[0063] Specifically, during use, when the support rod 21 moves, the support rod 21 compresses the air bag 531, causing the gas in the air bag 531 to enter the air box 51 through the air tube 533, supplying air to the air box 51.
