Description

Technical Field

[0001] The present invention relates to the technical field of cables, and specifically to a cable with a lightning protection device. Background Art

[0002] Cable lightning protection devices are important protection equipment in the power system, mainly used to prevent lightning overvoltage from damaging cables and their connected equipment. Its 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 lightning arresters, surge protectors, and grounding devices, etc. A lightning arrester is the core component of cable lightning protection, usually installed at the input end of the cable or key nodes, which can quickly respond to lightning overvoltage, limit the overvoltage within a safe range, and prevent cable insulation breakdown. The surge protector is mainly used to suppress transient overvoltage and protect low-voltage cables and equipment from lightning damage. The grounding device effectively reduces the impact of lightning on the cable by introducing lightning current into the ground.

[0003] In thunderstorm and strong wind weather, cables may face multiple hazards, seriously affecting the safe operation of the power system. First of all, direct lightning strike or induced overvoltage may damage the cable. When lightning directly strikes the cable or the nearby area, extremely high overvoltage will be generated, which may cause cable insulation breakdown, and even lead to short circuit or fire. Induced overvoltage will generate transient high voltage on the cable line, damaging the cable and its connected electrical equipment. Secondly, strong wind weather may cause mechanical damage to the cable. Summary of the Invention

[0018] The present invention provides a cable with a lightning protection device, which has the following beneficial effects:

[0019] First, for the cable with a lightning protection device, by setting up a lightning protection mechanism, under thunderstorm weather conditions, this mechanism can effectively guide the lightning approaching the cable and safely introduce it into the grounding system of the lightning protection mechanism. The lightning protection mechanism adopts high-performance conductive materials and optimized electromagnetic field design, can quickly respond to lightning activities, form a low-impedance path, ensure that the lightning energy is efficiently discharged to the ground, and at the same time, the lightning protection mechanism also has a real-time monitoring function, can start the protection mechanism for the cable during thunderstorm weather, thus significantly improving the safety and stability of the electrical system.

[0020] Second, for the cable with a lightning protection device, by setting up an anti-breaking mechanism, under thunderstorm weather conditions, this mechanism can be started under the control of the lightning protection mechanism and firmly clamp the cable, effectively coping with the huge pulling force generated by strong winds on the cable. At the same time, the anti-breaking mechanism can adjust the clamping force, not only ensuring the stability of the cable, but also avoiding damage to the cable caused by excessive clamping, thus achieving all-round protection for the cable and significantly reducing the risk of cable breakage during thunderstorm weather.

[0021] III. The cable with a lightning protection device, by setting up a grounding mechanism, can quickly conduct the lightning energy to the ground under thunderstorm weather conditions when the lightning protection mechanism successfully guides the lightning approaching the cable. The grounding mechanism adopts a low-impedance material and a design of being buried deep underground to ensure that the lightning energy can be efficiently discharged along the shortest path and minimize the grounding resistance.

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

[0023] V. The cable with a lightning protection device, by setting up zinc oxide varistors, can achieve over-voltage protection for electrical equipment through its unique non-linear volt-ampere characteristics. Under normal working voltage, the zinc oxide varistors present a high-resistance state and hardly conduct current, thus ensuring the normal operation of the electrical system. When over-voltage occurs in the system, such as lightning strike or switching over-voltage, the resistance of the zinc oxide varistors will drop sharply, quickly discharge the over-voltage energy to the ground, limit the voltage amplitude, and protect the equipment from damage.

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

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

[0039] A lightning protection mechanism 3 for protecting electrical systems and equipment from overvoltage damage, and a first fixing frame 2 fixedly connected to the lower surface of the lightning protection mechanism 3. By providing the lightning protection mechanism 3, under thunderstorm weather conditions, this mechanism can effectively guide the lightning approaching the cable 1 and safely introduce 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, can quickly respond to lightning activities, form a low-impedance path, ensure that the lightning energy is efficiently discharged to the ground, and at the same time, the lightning protection mechanism 3 also has a real-time monitoring function, can start the protection mechanism for the cable during thunderstorm weather, thus significantly improving the safety and stability of the electrical system;

[0040] The anti-breakage mechanism 5 is used to prevent the cable 1 from breaking during thunderstorms, and the limit box 4 arranged inside the anti-breakage mechanism 5. Based on the characteristics and physical behavior of lightning, lightning is a strong discharge phenomenon between clouds and the ground, usually occurring inside clouds or between clouds and the ground. Lightning tends to choose the shortest and most direct path for discharge because this can minimize resistance and release more energy. Therefore, lightning usually strikes the tallest objects on the ground. Thus, the first fixing frame 2, the lightning protection mechanism 3, and the anti-breakage device 5 are arranged at the highest point of the cable 1. And the highest point of the cable 1 often bears the greatest tensile force. Therefore, it is necessary to set the anti-breakage mechanism 5. By setting the anti-breakage mechanism 5, under thunderstorm weather conditions, this mechanism can be activated under the control of the lightning protection mechanism 3 and firmly clamp the cable 1, effectively coping with the huge tensile force generated by strong winds on the cable 1. At the same time, the anti-breakage mechanism 5 can adjust the clamping force, ensuring both the stability of the cable 1 and avoiding damage to the cable 1 caused by excessive clamping, thereby achieving all-round protection of the cable 1 and significantly reducing the risk of the cable 1 breaking during thunderstorms. Under thunderstorm weather, the cable connection is easily affected by lightning strikes, strong winds, and rain erosion, resulting in a significant increase in the risk of breakage. The high voltage and strong current generated by lightning may directly penetrate the cable insulation layer, causing short circuits or burning. Strong winds will cause the cable to shake violently, increasing the mechanical stress at the connection. Rainwater penetration may cause corrosion, weakening the mechanical strength and electrical conductivity of the cable. Therefore, it can cause the cable connection to break, and it is necessary to set the anti-breakage mechanism. The anti-breakage mechanism can automatically clamp the section of the cable that discharges lightning during thunderstorms, increasing the strength of the cable and reducing the risk of the entire device falling off the cable during thunderstorms;

The grounding mechanism 7 adopts a low-impedance material and a design of being buried deep underground to ensure that the lightning energy can be efficiently discharged along the shortest path, minimizing the grounding resistance to the greatest extent;

By providing the lightning arrester 36, under thunderstorm weather conditions, the mechanism can effectively guide the lightning approaching the cable 1 and safely introduce it into the grounding system of the lightning protection mechanism 3.

At the same time, the silicone rubber umbrella group 362 has excellent hydrophobicity and anti-pollution ability, which can prevent dirt from accumulating on the surface of the umbrella skirt and reduce the occurrence probability of pollution flashover accidents. In addition, the silicone rubber umbrella group 362 has 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.

The end of the fourth wire 75 is fixedly connected to a second terminal 74. The second terminal 74 is connected to the cable 1. The output end of the overvoltage protector 76 is provided with a first conductive block 77. By providing the overvoltage protector 76, the cable 1 can be protected when it is connected to the cable 1. When an overvoltage occurs, the protector limits the voltage below the cable insulation withstand level to prevent insulation breakdown or damage. By providing the conductive plate 71 and the grounding wire 72, the high voltage released by the cable or lightning can be transmitted to the ground through the action of the conductive plate 71, the grounding wire 73 and the grounding block 73. A track frame 712 is fixedly connected to the upper surface of the second fixing frame 6. A sliding conductive column 711 is slidably connected to the inner cavity of the track frame 712. The end of the sliding conductive column 711 is fixedly connected to a conductive rod 713. The conductive rod 713 is movably connected to the first conductive block 77.

The end of the long wire 78 is fixedly connected to a second conductive block 79. The second conductive block 79 is fixedly connected to the upper surface of the second fixing frame 6. The second conductive block 79 is connected to the conductive rod 713. By providing 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, so that the conductive rod 713 is connected to the first conductive block 77 or connected to the second conductive block 79. By providing the long wire 78, the second wire 312 can be connected to the second conductive block 79. When the conductive rod 713 contacts the second conductive block 79, the lightning can enter the conductive plate 71 through the sliding conductive column 711 and the fifth wire 714, so that the current flows into the ground.

[0049] Working principle: When in use, during thunderstorm weather, water droplets, ice crystals, and graupel inside the cloud collide and rub under the action of strong updrafts, resulting in the separation of positive and negative charges. Positive charges accumulate in the upper part of the cloud, and negative charges accumulate in the lower part. The ground is positively charged due to induction. As the charges continue to accumulate, the electric field strength between the cloud and the ground or inside the cloud gradually increases. When the electric field strength exceeds the breakdown threshold of air, approximately 3000 kV / m, the air is ionized to form a conductive channel. Attracted by the lightning rod 3612, lightning is transmitted through the lightning rod 3612 and the copper column 3611 to the connecting copper wire 3610. Under normal operating voltage, the zinc oxide varistor 366 presents a high-resistance state and hardly conducts current, thus ensuring the normal operation of the electrical system. When the system experiences overvoltage, such as lightning strike or switching overvoltage, the resistance of the zinc oxide varistor 366 drops sharply, quickly discharging the overvoltage energy and transmitting it to the first electrical connection post 364 and the adapter 311. Under the influence of the current, the central processor 38 controls the hydraulic press 37 to start working, so that the hydraulic rod 310 drives the connecting frame 518 to move horizontally. Then, the sliding plate 517 drives the second limiting frame 516 to move horizontally in the inner cavity of the limiting box 4, and further makes the third pressing wheel 520 roll on the lower surface of the cable 1. Then, under the pulling of the second support rod 512, the second pressing wheel 510 moves downward and presses the upper surface of the cable 1 to achieve the reinforcement work of the cable. During the horizontal movement of the connecting frame 518, the connecting rod 710 drives the sliding conductive column 711 to move horizontally, and further makes the conductive rod 713 insert into the second conductive block 79, so that the current can flow into the conductive rod 713 and the sliding conductive column 711 through the long wire 78, and flow into the conductive plate 71 through the fifth wire 714, and finally flow 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, so that the overvoltage protector 76 is connected to the circuit of the cable 1, thus achieving the effect of overvoltage protection.
