[0002] In modern power transmission systems, high-voltage transmission lines, as the key carriers of power transmission, their safe and stable operation is of crucial importance. Lightning arresters, as important devices to protect high-voltage transmission lines from overvoltage damage such as lightning strikes, are widely used in various high-voltage transmission scenarios.
[0003] The Chinese invention patent with the publication number CN107134715A discloses a lightning arrester device for transmission lines and its installation method. There are many problems in the process of installing and disassembling such lightning arresters on high-voltage transmission lines. Traditional installation and disassembly methods often involve complex operation procedures and professional tools, requiring operators to have a high skill level and rich experience. For example, during the installation process, it is necessary to accurately adjust the position and angle of the lightning arrester to ensure that it can effectively play a protective role. This process is not only time-consuming and laborious, but also has extremely high technical requirements for operators.

[0022] (III) Beneficial effects
[0023] Compared with the prior art, the present invention provides a composite insulation lightning arrester applicable to high-voltage transmission lines, which has the following beneficial effects:
[0024] 1. During the reset process, the deformed spring 1 automatically pushes the locking rod into the locking hole, completing the tight locking of mounting base 1 and mounting base 2, and realizing the installation of the arrester body on the high-voltage transmission line. The locking cooperation between multiple locking rods and multiple locking holes can achieve the stable installation of the arrester body to prevent the arrester body from falling during long-term suspension, avoiding the risk of injury and reducing the replacement frequency. By pulling the circular ring plate 1, multiple locking rods and multiple locking holes can be separated simultaneously and quickly, realizing the rapid separation of mounting base 1 and mounting base 2, and further realizing the rapid disassembly of the arrester body, reducing the maintenance, replacement and installation difficulties for the operator.
[0025] 2. By deploying multiple heat dissipation fins 1 and multiple heat dissipation fins 2, it plays a role in shading to prevent the temperature of the arrester body from rising rapidly. And since they are distributed radially after deployment, it greatly increases the contact area between the arrester and the air. A larger surface area means more heat can be transferred to the air through heat conduction, reducing the temperature of the arrester body and increasing the service life of the arrester body.
[0026] 3. By deploying the windproof skirt to cover the bottom of the arrester body, it hinders the strong wind from directly impacting the bottom of the arrester body, reducing the swing amplitude of the arrester body, preventing the overall fall of the arrester body due to severe shaking, and also facilitating the extension of the service life of the installation component and the heat dissipation component.

The first mounting seat 21 includes a first splicing seat 213, a second splicing seat 214, and a first bolt 215. Threaded holes one and two for inserting the first bolt 215 are respectively provided on the first splicing seat 213 and the second splicing seat 214. The first bolt 215 sequentially passes through the threaded hole one and the threaded hole two to connect the first splicing seat 213 and the second splicing seat 214.

A first traction line 201 is connected to the locking rod 24. One end of each first traction line 201 is connected to a first circular plate. A second through hole 216 is provided on the first mounting seat 21;
[0045] Overview 1: Comparison with the prior art When installing the arrester body 1, the deformed spring 25 can automatically push the locking rod 24 into the locking hole 222 during the reset process, completing the tight locking of the first mounting seat 21 and the second mounting seat 22, and realizing the installation of the arrester body 1 on the high-voltage transmission line. The locking cooperation between multiple locking rods 24 and multiple locking holes 222 can achieve the stable installation of the arrester body 1 to prevent the arrester body 1 from falling during long-term suspension, avoiding the risk of injury to people and reducing the replacement frequency. By pulling the first circular ring plate, multiple locking rods 24 can be separated from multiple locking holes 222 simultaneously and quickly, realizing the quick separation of the first mounting seat 21 and the second mounting seat 22, and further realizing the quick disassembly of the arrester body 1, reducing the maintenance, replacement and installation difficulties of the operator. During the disassembly of the arrester body 1, after the operator approaches the arrester body 1, insert the finger into the second through hole 216 on the first mounting seat 21, and then pull down the first circular ring plate. The first circular ring plate drives each first traction wire 201 to move. Some parts of the first traction wire 201 move downward, and some parts of the first traction wire 201 move horizontally. During the movement, the first traction wire 201 pulls the locking rod 24 to move, causing the locking rod 24 to separate from the locking hole 222 and deforming the spring 25. Subsequently, move the entire first mounting seat 21 downward, and the hollow tube 23 gradually separates from the guide groove 221, and the first mounting seat 21 gradually separates from the second mounting seat 22.
[0046] Reference Figures 4-5 As shown, the heat dissipation component 3 is used to improve the heat dissipation speed of the arrester body 1, preventing the arrester body 1 from being damaged due to high temperature and thus affecting the long-term use of the arrester body 1;
[0047] Reference Figures 4-5As shown in the figure, the heat dissipation component 3 includes a second annular plate 31. The second annular plate 31 is sleeved outside the first mounting seat 21. A plurality of first rotating plates 32 are rotatably connected to the annular plate. A plurality of first connecting blocks 33 are connected to the outer wall of the first mounting seat 21. A first groove 331 is provided on the first connecting block 33. A first sliding plate 34 is slidably connected to the top of the first connecting block 33. The first rotating plate 32 can be rotated into the first groove 331 and locked by the first sliding plate 34. A plurality of first heat dissipation fins 35 are hinged to the second annular plate 31. The first heat dissipation fins 35 are distributed in an annular array around the second annular plate 31. A temperature sensor 37, a controller 38 and a first driving motor 39 are arranged in the inner cavity 211. The temperature sensor 37, the controller 38 and the first driving motor 39 are respectively connected to the inner cavity wall of the inner cavity 211 through a first support plate 301, a second support plate 302 and a third support plate 303. The first support plate 301, the second support plate 302 and the third support plate 303 do not block the inner cavity 211 to avoid affecting the movement of the first traction line 201. A plurality of second traction lines 304 are connected to the first driving motor 39. Each second traction line 304 is respectively connected to each first heat dissipation fin 35 to pull each first heat dissipation fin 35 to rotate. A second heat dissipation fin 36 is rotatably connected to each first heat dissipation fin 35. A third through hole and a fourth through hole are respectively formed in the first heat dissipation fin 35 and the second heat dissipation fin 36. A fixing structure is inserted into the third through hole or the fourth through hole. The fixing structure can move horizontally and rotate. The fixing structure is in a U shape. Both ends of the fixing structure can be inserted into the third through hole and the fourth through hole at the same time so that the first heat dissipation fin 35 and the second heat dissipation fin 36 are arranged side by side;
[0048] Summary II: Compared with the prior art, when the temperature is relatively high, the temperature sensor 37 detects the high-temperature information and then transmits the high-temperature information to the controller 38. The controller 38 controls the first driving motor 39 to start. The first driving motor 39 pays out the second traction line 304. The second traction line 304 stops applying force to the first heat dissipation fin 35. The first heat dissipation fin 35 rotates downward under the action of gravity. A spring structure can also be set to promote the downward rotation of the first heat dissipation fin 35. The first heat dissipation fin 35 is supported by the second annular plate 31. When disassembling the second annular plate 31, move the first sliding plate 34 to separate the connecting column from the first groove 331. After the plurality of first heat dissipation fins 35 and the plurality of second heat dissipation fins 36 are unfolded, they can play a role in shading to avoid the rapid rise of the temperature of the lightning arrester body 1. And because they are distributed in a radial shape after unfolding, the contact area between the lightning arrester and the air is greatly increased. A larger surface area means that more heat can be transferred to the air by heat conduction, reducing the temperature of the lightning arrester body 1 and improving the service life of the lightning arrester body 1.
[0049] Reference Figure 10 As shown in the figure, the windproof component 4 is used to block the direct impact of strong wind on the bottom of the lightning arrester body 1 and reduce the shaking and displacement of the lightning arrester body 1 caused by the wind force;
[0050] ReferenceFigure 10 As shown in the figure, the windproof component 4 includes a windproof skirt 41. The windproof skirt 41 is arranged at the bottom of the lightning arrester body 1. The windproof skirt 41 covers the bottom of the lightning arrester body 1 to prevent strong wind from directly impacting the bottom of the lightning arrester body 1. The windproof skirt 41 is made of rubber material. A wind speed sensor 42 is arranged at the bottom end of the lightning arrester body 1. The windproof skirt 41 is connected to the bottom of the lightning arrester body 1 through a rotating mechanism. The rotating mechanism includes a plurality of connecting rods one 43 and a plurality of rotating rods 44. The plurality of rotating rods 44 are respectively rotatably connected to the plurality of connecting rods one 43. The windproof skirt 41 is connected to the plurality of rotating rods 44. A driving motor two 45 is arranged at the bottom of the lightning arrester body 1. The driving motor two 45 is connected with a connecting rod two 46. A plurality of push rods 47 are connected to the connecting rod two 46. The plurality of push rods 47 are opposite to the plurality of rotating rods 44 to promote the unfolding and retracting of the windproof skirt 41.
[0051] Summary three: Compared with the prior art, when the wind speed sensor 42 detects a large wind speed, it transmits the information to the controller 38. The controller 38 controls the driving motor two 45 to start. The driving motor two 45 pushes the connecting rod two 46 downward. The connecting rod two 46 drives each push rod 47 to push each rotating rod 44 to rotate downward so that the windproof skirt 41 unfolds. When the wind speed sensor 42 detects that the wind speed returns to normal, the controller 38 controls the driving motor two 45 again. The driving motor two 45 pulls the connecting rod two 46 upward. The connecting rod two 46 gradually drives the windproof skirt 41 to retract through the push rod 47 and the rotating rod 44. When the windproof skirt 41 unfolds, the windproof skirt 41 covers the bottom of the lightning arrester body 1 to prevent strong wind from directly impacting the bottom of the lightning arrester body 1, reduce the swing amplitude of the lightning arrester body 1, avoid the situation that the whole lightning arrester body 1 drops due to violent shaking, and is also beneficial to extending the service life of the installation component 2 and the heat dissipation component 3.
[0052] The following is the working process and principle of the above embodiment:
[0053] Initial state: The heat dissipation fins one 35 and the heat dissipation fins two 36 are placed vertically. The windproof skirt 41 is in a retracted state. The driving motor one 39 and the driving motor two 45 are not started.
[0054] Working steps:
[0055] In the installation component 2, the first mounting seat 21 is arranged on the top of the lightning arrester body 1, and the second mounting seat 22 is installed on the high-voltage transmission line. When installing the lightning arrester body 1, the first mounting seat 21 and the second mounting seat 22 need to be docked. When disassembling the lightning arrester body 1, the first mounting seat 21 and the second mounting seat 22 need to be separated. The following takes the replacement of the lightning arrester body 1 by disassembling it as an example. During the process of disassembling the lightning arrester body 1, after the operator approaches the lightning arrester body 1, the operator inserts a finger into the second through hole 216 on the first mounting seat 21, and then pulls down the first ring plate. The first ring plate drives each first traction wire 201 to move. Some parts of the first traction wire 201 move downward, and some parts of the first traction wire 201 move horizontally. During the movement of the first traction wire 201, the locking rod 24 is pulled to move, so that the locking rod 24 is separated from the locking hole 222 and the first spring 25 is deformed. Subsequently, the entire first mounting seat 21 is moved downward, the hollow tube 23 is gradually separated from the guide groove 221, and the first mounting seat 21 is gradually separated from the second mounting seat 22. When installing the lightning arrester body 1, the deformed first spring 25 can automatically push the locking rod 24 into the locking hole 222 during the reset process, completing the tight locking of the first mounting seat 21 and the second mounting seat 22, and realizing the installation of the lightning arrester body 1 on the high-voltage transmission line. The locking cooperation between the multiple locking rods 24 and the multiple locking holes 222 can realize the stable installation of the lightning arrester body 1 to prevent the lightning arrester body 1 from falling during the long-term hanging process, avoiding the risk of injury to people and reducing the replacement times. By pulling the first ring plate, the multiple locking rods 24 and the multiple locking holes 222 can be separated simultaneously and quickly, realizing the quick separation of the first mounting seat 21 and the second mounting seat 22, and further realizing the quick disassembly of the lightning arrester body 1, reducing the maintenance, replacement and installation difficulty of the operator.
[0056] After the arrester body 1 is installed, the heat dissipation component 3 is put into use. Heat dissipation is carried out by the first heat dissipation fin 35 and the second heat dissipation fin 36. Since it is at high altitude, generally both the first heat dissipation fin 35 and the second heat dissipation fin 36 are used simultaneously. The first heat dissipation fin 35 and the second heat dissipation fin 36 are arranged side by side. By inserting the two ends of the door-shaped fixing structure into the third through hole and the fourth through hole respectively, the first heat dissipation fin 35 and the second heat dissipation fin 36 are stably arranged side by side. Normally, the first heat dissipation fin 35 and the second heat dissipation fin 36 are vertically arranged to avoid affecting the appearance of the arrester. When the temperature is relatively high, the temperature sensor 37 detects the high-temperature information and then transmits the high-temperature information to the controller 38. The controller 38 controls the first driving motor 39 to start. The first driving motor 39 unwinds and pulls the second traction line 304. The second traction line 304 stops applying force to the first heat dissipation fin 35. The first heat dissipation fin 35 rotates downward under the action of gravity. A spring structure can also be set to promote the downward rotation of the first heat dissipation fin 35. The first heat dissipation fin 35 is supported by the second circular ring plate 31. When disassembling the second circular ring plate 31, move the first sliding plate 34 to separate the connecting column from the first groove 331. After multiple first heat dissipation fins 35 and multiple second heat dissipation fins 36 are unfolded, they can play a role in shading to avoid the rapid rise of the temperature of the arrester body 1. And since they are radially distributed after unfolding, it greatly increases the contact area between the arrester and the air. A larger surface area means that more heat can be transferred to the air by heat conduction, reducing the temperature of the arrester body 1 and improving the service life of the arrester body 1.
[0057] After the arrester body 1 is installed, the windproof component 4 is put into use. The windproof skirt 41 is normally in a retracted state. At this time, the windproof skirt 41 does not cover the bottom of the arrester body 1 to avoid affecting the appearance. When the wind speed sensor 42 detects a relatively high wind speed, it transmits the information to the controller 38. The controller 38 controls the second driving motor 45 to start. The second driving motor 45 pushes the second connecting rod 46 downward. The second connecting rod 46 drives each push rod 47 to push each rotating rod 44 downward to unfold the windproof skirt 41. When the wind speed sensor 42 detects that the wind speed returns to normal, the controller 38 controls the second driving motor 45 again. The second driving motor 45 pulls the second connecting rod 46 upward. The second connecting rod 46 gradually drives the windproof skirt 41 to retract through the push rod 47 and the rotating rod 44. When the windproof skirt 41 is unfolded, the windproof skirt 41 covers the bottom of the arrester body 1 to prevent strong wind from directly impacting the bottom of the arrester body 1, reducing the swing amplitude of the arrester body 1 and avoiding the situation that the entire arrester body 1 falls due to violent shaking. It is also beneficial to extend the service time of the installation component 2 and the heat dissipation component 3.
