Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a cable with a lightning protection device. Background Technology

[0002] Cable lightning protection devices are crucial protective equipment in power systems, primarily used to prevent damage to cables and connected equipment caused by lightning overvoltages. Their core function is to ensure the normal operation of cables and equipment by discharging lightning current or limiting overvoltage. Common cable lightning protection devices include surge arresters, surge protectors, and grounding devices. Surge arresters are the core component of cable lightning protection, typically installed at the cable's input end or critical nodes. They can quickly respond to lightning overvoltages, limiting the overvoltage to a safe range and preventing cable insulation breakdown. Surge protectors are mainly used to suppress transient overvoltages, protecting low-voltage cables and equipment from lightning strikes. Grounding devices effectively reduce the impact of lightning strikes on cables by diverting lightning current to the earth.

[0003] During thunderstorms and strong winds, cables may face multiple hazards, seriously affecting the safe operation of the power system. First, direct lightning strikes or induced overvoltages may damage cables. When lightning strikes a cable or nearby area, it will generate extremely high overvoltages, which may cause cable insulation breakdown or even short circuits or fires. Induced overvoltages will generate transient high voltages on the cable line, damaging the cable and the electrical equipment connected to it. Second, strong winds may cause mechanical damage to cables. Summary of the Invention

The lightning arrester adopts high-performance conductive materials and optimized electromagnetic field design, which can quickly respond to lightning activity, form a low impedance path, and ensure that lightning energy is efficiently discharged to the ground. At the same time, the lightning arrester also has a real-time monitoring function, which can activate the cable protection mechanism during thunderstorms, thereby significantly improving the safety and stability of the electrical system.

[0006] The anti-breakage mechanism is used to prevent cables from breaking during thunderstorms. The limiting box installed inside the anti-breakage mechanism can be activated and firmly clamp the cable under the control of the lightning protection mechanism during thunderstorms. This effectively copes with the huge pulling force of strong winds on the cable.

[0018] This invention provides a cable with a lightning protection device. It has the following beneficial effects:

[0019] I. This cable equipped with a lightning protection device, through the installation of a lightning arrester mechanism, can effectively guide lightning approaching the cable during thunderstorms, safely directing it into the grounding system of the lightning arrester mechanism. The lightning arrester mechanism adopts high-performance conductive materials and optimized electromagnetic field design, enabling it to respond quickly to lightning activity, form a low-impedance path, and ensure that lightning energy is efficiently discharged to the ground. At the same time, the lightning arrester mechanism also has a real-time monitoring function, which can activate the cable protection mechanism during thunderstorms, thereby significantly improving the safety and stability of the electrical system.

[0021] Third, this cable equipped with lightning protection devices, through the installation of a grounding mechanism, can quickly conduct lightning energy to the ground after the lightning protection mechanism successfully guides the lightning approaching the cable during thunderstorms. The grounding mechanism adopts low-impedance materials and a deep underground design to ensure that lightning energy can be efficiently discharged along the shortest path, minimizing grounding resistance.

[0022] IV. This cable with lightning protection device, through the installation of silicone rubber umbrellas, has insulation and protection functions. Its functions include insulation protection, anti-flashover performance, weather resistance, mechanical strength, moisture and humidity protection, reduction of equipment weight, and improvement of electric field distribution. As an insulating component, the silicone rubber umbrellas can effectively isolate high-voltage equipment from the external environment, preventing current leakage or short circuits. Its high insulation performance ensures stable operation of the equipment under high-voltage conditions. At the same time, the silicone rubber umbrellas have excellent hydrophobicity and anti-pollution ability, which can prevent dirt from accumulating on the surface of the umbrella skirts and reduce the probability of flashover accidents. In addition, the silicone rubber umbrellas have excellent high temperature resistance, ultraviolet resistance, and aging resistance, and can maintain stable physical and electrical properties for a long time under extreme weather conditions.

[0023] V. The cable equipped with a lightning protection device uses zinc oxide varistors, which utilize their unique nonlinear volt-ampere characteristics to protect electrical equipment from overvoltage. Under normal operating voltage, the zinc oxide varistors exhibit high resistance and conduct almost no current, thus ensuring the normal operation of the electrical system. However, when an overvoltage occurs in the system, such as a lightning strike or operational overvoltage, the resistance of the zinc oxide varistors drops sharply, rapidly dissipating the overvoltage energy to the ground, limiting the voltage amplitude, and protecting the equipment from damage.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0038] like Figures 1-12 As shown, the present invention provides a technical solution: a cable with a lightning protection device, including cable 1, for transmitting power;

[0039] The lightning protection mechanism 3 is used to protect electrical systems and equipment from overvoltage damage. The first fixing frame 2, which is fixedly connected to the lower surface of the lightning protection mechanism 3, can effectively guide lightning approaching the cable 1 under thunderstorm conditions and safely conduct it into the grounding system of the lightning protection mechanism 3. The lightning protection mechanism 3 adopts high-performance conductive materials and optimized electromagnetic field design, which can quickly respond to lightning activity, form a low impedance path, and ensure that lightning energy is efficiently discharged to the ground. At the same time, the lightning protection mechanism 3 also has a real-time monitoring function, which can activate the protection mechanism for the cable in thunderstorms, thereby significantly improving the safety and stability of the electrical system.

[0040] The anti-breakage mechanism 5 is used to prevent cable 1 from breaking during thunderstorms. A limiting box 4 is installed inside the anti-breakage mechanism 5. Based on the characteristics and physical behavior of lightning, which is a strong discharge phenomenon between clouds and the ground, typically occurring within clouds or between clouds and the ground, lightning tends to choose the shortest and most direct path to discharge, minimizing resistance and releasing more energy. Therefore, lightning usually strikes the highest object on the ground. Thus, the first fixing frame 2, the lightning protection mechanism 4, and the anti-breakage mechanism 5 are located at the highest point of cable 1. The highest point of cable 1 often experiences the greatest tension, hence the need for the anti-breakage mechanism 5. By installing the anti-breakage mechanism 5, under the control of the lightning protection mechanism 3, it can activate and firmly clamp cable 1 during thunderstorms, effectively counteracting the enormous tension exerted on cable 1 by strong winds. The anti-breakage mechanism 5 can adjust the clamping force to ensure the stability of cable 1 while avoiding damage caused by excessive clamping, thus achieving all-round protection for cable 1 and significantly reducing the risk of cable 1 breaking during thunderstorms. During thunderstorms, cable connections are easily affected by lightning strikes, strong winds, and rainwater erosion, leading to a significant increase in the risk of breakage. The high voltage and strong current generated by lightning may directly break through the cable insulation layer, causing short circuits or burnout. Strong winds will cause the cable to shake violently, exacerbating the mechanical stress at the connection. Rainwater penetration may cause corrosion, weakening the mechanical strength and conductivity of the cable, thus potentially causing cable connection breakage. Therefore, an anti-breakage mechanism is needed. The anti-breakage mechanism can automatically clamp the section of the cable exposed to lightning during thunderstorms, increasing the cable's strength while reducing the risk of the entire device and cable detaching during thunderstorms.

[0041] The grounding mechanism 7 is used to transfer the current absorbed by the lightning arrester 3 to the ground. A second fixing frame 6 is fixedly connected to the lower surface of the grounding mechanism 7. By setting up the grounding mechanism 7, under thunderstorm conditions, when the lightning arrester 3 successfully guides lightning approaching the cable 1, the grounding mechanism 7 can quickly conduct the lightning energy to the ground. The grounding mechanism 7 uses low-impedance materials and is deeply buried underground to ensure that lightning energy can be efficiently discharged along the shortest path, minimizing grounding resistance.

The lightning protection mechanism 3 is fixedly connected to the outer surface of the cable 1 through the first fixing frame 2. The limiting box 4 is fixedly connected to the outer side of the first fixing frame 2. The anti-breakage mechanism 5 is sleeved on the outer surface of the cable 1 through the limiting box 4. The second fixing frame 6 is fixedly connected to the outer surface of the cable 1. The grounding mechanism 7 is fixedly connected to the outer surface of the cable 1 through the second fixing frame 6.

A connecting box 32 is fixedly connected to the upper surface of the fixing plate 31, and a mounting plate 33 is fixedly connected to the upper surface of the connecting box 32. A threaded ring 34 passes through the upper surface of the mounting plate 33. A lightning arrester 36 is arranged directly above the mounting plate 33. The lightning arrester 36 includes a mounting frame 361, which is located directly above the mounting plate 33. A threaded rod 35 is threadedly connected to the inner cavity of the threaded ring 34. The mounting frame 361 is connected to the threaded ring 34 via the threaded rod 35. By setting the connecting box 32 and the mounting plate 33, the surge arrester 36 can be connected to the first fixed frame 2. By setting the threaded ring 34, the threaded rod 35 can be limited, so that when the threaded rod 35 rotates, the surge arrester 36 can be tightly connected to the mounting plate 33. By setting the surge arrester 36, the mechanism can effectively guide the lightning approaching the cable 1 under thunderstorm conditions and safely conduct it into the grounding system of the surge arrester mechanism 3.

[0044] A silicone rubber umbrella group 362 is fixedly connected to the inner ring of the mounting frame 361. A positioning ring 363 is fixedly connected to the bottom of the inner wall of the silicone rubber umbrella group 362. A first electrical contact post 364 is fixedly connected to the inner wall of the positioning ring 363. An anti-slip pad 365 is fixedly connected to the middle of the inner wall of the silicone rubber umbrella group 362. A zinc oxide valve plate 366 is slidably connected to the inner cavity of the anti-slip pad 365. The bottom end of the zinc oxide valve plate 366 is pressed and adapted to the top end of the first electrical contact post 364. An adapter 311 is fixedly connected to the bottom end of the electric pole 364. By incorporating a silicone rubber umbrella group 362, it provides insulation and protection functions, including insulation protection, anti-flashover performance, weather resistance, mechanical strength, moisture protection, weight reduction, and improved electric field distribution. As an insulating component, the silicone rubber umbrella group 362 effectively isolates the high-voltage equipment from the external environment, preventing current leakage or short circuits. Its high insulation performance ensures stable operation of the equipment under high-voltage conditions. Furthermore, the silicone rubber umbrella group 362 exhibits excellent hydrophobicity. The silicone rubber umbrella group 362 possesses excellent resistance to high temperatures, ultraviolet radiation, and aging, preventing the accumulation of dirt on the umbrella skirt surface and reducing the probability of flashover accidents. Furthermore, it maintains stable physical and electrical properties under extreme weather conditions. The positioning ring 363 positions and fixes the first terminal 364, while the anti-slip pad 365 supports and positions the zinc oxide valve plate 366, preventing it from detaching from the inner cavity of the silicone rubber umbrella group 362. The zinc oxide valve plate 366 utilizes its unique nonlinear volt-ampere characteristics to provide overvoltage protection for electrical equipment. Under normal operating voltage, the zinc oxide valve plate 366 exhibits high resistance and conducts almost no current, ensuring the normal operation of the electrical system. However, when an overvoltage occurs, such as from a lightning strike or operational overvoltage, the resistance of the zinc oxide valve plate 366 drops sharply, rapidly dissipating the overvoltage energy to the ground, limiting the voltage amplitude, and protecting the equipment from damage.

A lightning rod 3612 is fixedly connected to the outer surface of the copper column 3611. By setting a first spring 368, elastic potential energy can be generated, which in turn causes the extrusion frame 369 to drive the connecting copper wire 3610 to the top of the zinc oxide valve plate 366. By setting the copper column 3611 and the lightning rod 3612, the high-voltage current threatening the cable 1 can be conducted during thunderstorms, so that lightning can be transmitted to the connecting copper wire 3610 through the lightning rod 3612 and the copper column 3611, and then transmitted to the zinc oxide valve plate 366 through the connecting copper wire 3610.

By setting up the hydraulic press 37, the output end of the hydraulic press 37 can be moved under the control of the central processing unit 38, thereby causing the hydraulic rod 310 to move laterally, thus changing the state of the anti-breakage mechanism 5. By setting up the central processing unit 38, the current can be detected, and when the current exceeds a threshold, the working state of the hydraulic press 37 can be controlled. By setting up the first wire 39, the hydraulic press 37 and the central processing unit 38 can be connected together.

A fifth wire 714 is fixedly connected to the side of the sliding conductive post 711 away from the conductive rod 713. The end of the fifth wire 714 is connected to a conductive plate 71. A connecting rod 710 is fixedly connected to the outer surface of the sliding conductive post 711, with its end fixedly connected to the outer surface of a connecting frame 518. A long wire 78 is fixedly connected to the end of a second wire 312, and a second conductive block 79 is fixedly connected to the end of the long wire 78. Block 79 is fixedly connected to the upper surface of the second fixed frame 6. The second conductive block 79 is connected to the conductive rod 713. By setting the track frame 712, the sliding conductive column 711 can be limited, so that the sliding conductive column 711 can produce a lateral back-and-forth movement effect, thereby connecting the conductive rod 713 to the first conductive block 77 or to the second conductive block 79. By setting the long wire 78, the second wire 312 can be connected to the second conductive block 79, so that when the conductive rod 713 contacts the second conductive block 79, lightning can enter the conductive plate 71 through the sliding conductive column 711 and the fifth wire 714, thereby causing the current to flow into the ground.

[0049] Working principle: During thunderstorms, water droplets, ice crystals, and graupel within clouds collide and rub against each other under strong updrafts, causing positive and negative charges to separate. Positive charges accumulate in the upper part of the cloud, while negative charges accumulate in the lower part. The ground becomes positively charged due to induction. As the charge accumulates, the electric field strength between the cloud and the ground, or within the cloud, gradually increases. When the electric field strength exceeds the air breakdown threshold of approximately 3000 kV / m, the air is ionized, forming a conductive channel. The lightning rod... Attracted by lightning, lightning is transmitted through lightning rod 3612 and copper post 3611 to connecting copper wire 3610. Under normal operating voltage, zinc oxide varistor 366 exhibits high resistance and conducts almost no current, thus ensuring the normal operation of the electrical system. However, when an overvoltage occurs in the system, such as a lightning strike or operational overvoltage, the resistance of zinc oxide varistor 366 drops sharply, rapidly dissipating the overvoltage energy and transmitting it to the first terminal 364 and adapter 311. Under the influence of the current, the central processing unit 38... The hydraulic press 37 is started to work, causing the hydraulic rod 310 to drive the connecting frame 518 to move laterally. Then, the sliding plate 517 drives the second limit frame 516 to move laterally in the inner cavity of the limit box 4, thereby causing the third extrusion wheel 520 to roll on the lower surface of the cable 1. Then, under the pull of the second support rod 512, the second extrusion wheel 510 moves downward and extrudes the upper surface of the cable 1 to achieve the reinforcement of the cable. During the lateral movement of the connecting frame 518, the connecting rod 710 drives the sliding conductive post 711 to move laterally, thereby causing the conductive rod 713 to be inserted into the second conductive block 79. This allows the current to flow through the long wire 78 into the conductive rod 713 and the sliding conductive post 711, and then through the fifth wire 714 into the conductive plate 71, and finally into the ground through the grounding wire 72 and the grounding block 73. When the cable 1 is not affected by lightning, the conductive rod 713 is in contact with the first conductive block 77, thereby connecting the overvoltage protector 76 into the circuit of the cable 1, thus achieving the effect of overvoltage protection.
