Description

Technical Field

[0001] This utility model relates to the technical field of multi-chamber gap lightning protection devices, specifically a multi-chamber gap collaborative operation lightning protection device that is resistant to breakdown. Background Technology

[0002] In power systems, lightning strikes generate lightning current that is injected into the system instantaneously, resulting in extremely high overvoltages and overcurrents. This can not only directly break down the insulation layer of power equipment, causing equipment damage, but also trigger short circuits, tripping, and other faults, leading to local or large-scale power outages. Therefore, multi-chamber gap surge protection devices are needed. However, existing multi-chamber gap surge protection devices are prone to breakdown or damage under lightning strikes due to insufficient insulation performance of the materials used in them, causing the devices to malfunction.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese patent application number: 202120939525.7, application date: April 30, 2021) discloses a 10kV multi-chamber gap lightning protection device, comprising a main body, an insulator disposed on the top of the main body, a threaded head fixedly connected to the bottom center of the insulator, an arc-starting head fixedly connected to the top of the insulator, a conductor disposed on the top of the arc-starting head, an insulating layer disposed on the outside of the insulator, a protective shell not fixedly installed on the outside of the insulating layer, a discharge mechanism fixedly connected to the right side of the arc-starting head, a fixing mechanism movably installed at the bottom of the threaded head, and a support block included in the discharge mechanism. This 10kV multi-chamber gap lightning protection device, through the combined action of the insulating layer and the protective shell, allows the insulating layer to insulate against external lightning and current, while the protective shell protects the insulator internally, preventing external factors from affecting the internal insulator, thereby achieving the function of protecting the lightning protection device.

[0004] Although existing technologies can protect lightning protection devices, the design of the discharge mechanism increases the complexity of the device, which can easily lead to the lightning protection device malfunctioning and thus failing to effectively release lightning current. Furthermore, the insulation layer is affected by environmental factors such as temperature and humidity. In high-temperature or humid environments, the insulation performance of the insulation layer may decrease, thereby reducing the protective effect of the lightning protection device. This renders the lightning protection device without the functions of breakdown resistance and high-efficiency lightning protection. In addition, the lack of a multi-chamber gap structure makes it impossible to effectively guide and disperse lightning.

[0005] Therefore, we proposed a multi-chamber gap-coordinated lightning protection device that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-chamber gap coordinated operation lightning protection device that is resistant to breakdown, in order to solve the problems mentioned in the background art. However, the design of the discharge mechanism of the current multi-chamber gap lightning protection device increases the complexity of the device, which can easily lead to the lightning protection device failing to work properly. As a result, the lightning current cannot be effectively discharged. Furthermore, the insulation layer is affected by environmental factors such as temperature and humidity. In high temperature or humid environments, the insulation performance of the insulation layer may decrease, thereby reducing the protective effect of the lightning protection device. This means that the lightning protection device does not have the characteristics of breakdown resistance and high-efficiency lightning protection. In addition, the lack of a multi-chamber gap structure makes it impossible to effectively guide and disperse lightning.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-chamber gap coordinated lightning protection device with breakdown resistance, comprising a lightning protection device, the lightning protection device including a lightning rod, an upper lightning protection ball fixedly installed on the outer wall of the lightning rod, five upper lightning protection sleeves fixedly installed on the outer wall of the lightning rod, and a lower lightning protection ball fixedly installed on the outer wall of the lightning rod; a mounting base fixedly connected to the bottom of the lightning rod, a lead pipe fixedly installed at the bottom of the mounting base, four insulating posts fixedly connected to the bottom of the mounting base, and the four insulating posts located on the outer wall of the mounting base, and several lower lightning protection sleeves fixedly installed on the outer wall of the four insulating posts; a base fixedly connected to the bottom of the lead pipe, five grounding nails movably connected inside the base, and the lightning protection device internally provided with lightning protection components for multi-chamber gap coordinated operation.

[0008] As a preferred technical solution of this application, the lightning protection component includes an epoxy fiberglass core rod, and the end of the epoxy fiberglass core rod passes through a lead tube. An epoxy fiberglass cylinder is fixedly connected to the outer wall of the epoxy fiberglass core rod, and a polymer filling layer is fixedly connected to the outer wall of the epoxy fiberglass cylinder. A silicone rubber skirt is wrapped around the outer wall of the polymer filling layer, and a plurality of first valve plates are fixedly installed on the outer wall of the epoxy fiberglass core rod.

[0009] As a preferred technical solution of this application, the lightning rod and the lead pipe are connected in a continuous manner, and the lightning rod and the upper lightning protection ball are tightly fitted together. The lightning current then flows along the lightning rod through the mounting base and the lead pipe, and is safely discharged into the ground through the grounding nail inside the base.

[0010] As a preferred technical solution of this application, the upper lightning protection ball has a first cavity inside, and a plurality of second valve plates are arranged inside the first cavity, each of the second valve plates being located on the outer wall of the epoxy fiberglass core rod.

[0011] As a preferred technical solution of this application, the lower lightning protection ball has a second cavity inside, and multiple third valve plates are arranged inside the second cavity. Each third valve plate is located on the outer wall of the epoxy fiberglass core rod. The multiple second valve plates and the third valve plates located on the outer wall of the epoxy fiberglass core rod form a multi-chamber structure.

[0012] As a preferred technical solution of this application, the epoxy fiberglass cylinder and the epoxy fiberglass core rod are connected by a wrapping connection, and the epoxy fiberglass cylinder is made of epoxy resin material. The epoxy fiberglass cylinder is wrapped around the outer wall of the epoxy fiberglass core rod to form a first layer of insulation protection. It is made of epoxy resin material and has good insulation performance and mechanical strength.

[0013] As a preferred technical solution of this application, the polymer filling layer is tightly bonded to the epoxy fiberglass cylinder and the silicone rubber skirt, and the polymer filling layer is made of polyimide material. Because the polymer filling layer is made of polyimide material, it has excellent heat resistance, chemical corrosion resistance and electrical insulation properties, which can ensure the long-term stable operation of the lightning protection device in harsh environments.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This multi-chamber gap-coordinated lightning protection device, with its breakdown-resistant design, facilitates effective discharge of lightning current by incorporating a lightning rod, mounting base, and lead pipe. Furthermore, the inclusion of an epoxy fiberglass core rod, a first valve plate, an epoxy fiberglass cylinder, a polymer filling layer, and a silicone rubber skirt ensures that the multi-chamber gap-coordinated lightning protection device possesses breakdown resistance and high-efficiency lightning protection. Additionally, the inclusion of an upper and lower lightning arrester ball facilitates the guidance and dispersion of lightning by the multi-chamber gap-coordinated lightning protection device. Specific details are as follows:

[0015] 1. A lightning rod, mounting base, and lead conduit are installed. When lightning strikes the lightning rod directly, the lightning current is first introduced into the lightning protection device through the lightning rod. The design of the lightning rod enables it to preferentially attract lightning, thereby protecting surrounding buildings or equipment from direct lightning damage. The lightning current then flows along the lightning rod through the mounting base and lead conduit, and is safely discharged into the ground through the grounding nail inside the base, achieving effective discharge of the lightning current.

[0016] Furthermore, the system incorporates an epoxy fiberglass core rod, first valve plates, an epoxy fiberglass cylinder, a polymer filler layer, and a silicone rubber skirt. The epoxy fiberglass core rod conducts lightning current, while several first valve plates limit voltage during overvoltage events, preventing lightning current from causing breakdown of the lightning protection device. The epoxy fiberglass cylinder forms the first layer of insulation protection, the polymer filler layer provides additional insulation and mechanical support, and the silicone rubber skirt can quickly extinguish the arc after a lightning strike, preventing line tripping or equipment damage. This multi-chamber gap-coordinated operation lightning protection device achieves breakdown resistance and high-efficiency lightning protection.

[0017] 2. An upper and lower lightning protection ball is installed. When lightning current flows into the cavity opened in the upper and lower lightning protection ball, multiple second and third valve plates in the cavity will play a voltage limiting role during overvoltage, which can disperse lightning energy and prevent lightning current from breaking down the lightning protection device. This realizes the multi-chamber gap collaborative operation type of lightning protection device to guide and disperse lightning, which not only improves the lightning protection performance, but also further resists breakdown.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides the following technical solution:

[0027] Example 1: While multi-chamber gap surge protection devices on the market offer advantages, their complex design of the discharge mechanism increases complexity, potentially leading to malfunctions and ineffective lightning current release. Furthermore, the insulation layer is susceptible to environmental factors such as temperature and humidity; in high-temperature or humid environments, its insulation performance may deteriorate, reducing the protective effect and rendering the device ineffective in terms of breakdown resistance and high-efficiency lightning protection. This example discloses the following technical details of a breakdown-resistant multi-chamber gap coordinated operation surge protection device, which can be referenced in the appendix. Figure 1 - Appendix Figure 5 The system includes a lightning protection device body 1, which includes a lightning rod 2. An upper lightning protection ball 3 is fixedly installed on the outer wall of the lightning rod 2. Five upper lightning protection sleeves 4 are fixedly installed on the outer wall of the lightning rod 2. A lower lightning protection ball 5 is fixedly installed on the outer wall of the lightning rod 2. A mounting base 6 is fixedly connected to the bottom of the lightning rod 2. A lead pipe 7 is fixedly installed at the bottom of the mounting base 6. Four insulating posts 8 are fixedly connected to the bottom of the mounting base 6, and the four insulating posts 8 are located on the outer wall of the mounting base 6. Several lower lightning protection sleeves 9 are fixedly installed on the outer wall of the four insulating posts 8. A base 10 is fixedly connected to the bottom of the lead pipe 7. Five grounding nails 11 are movably connected inside the base 10. The lightning protection device body 1 is internally equipped with a lightning protection assembly for multi-chamber gap coordination. The lightning protection assembly includes an epoxy fiberglass core rod 12, with a lead tube 7 penetrating the end of the epoxy fiberglass core rod 12. An epoxy fiberglass cylinder 16 is fixedly connected to the outer wall of the epoxy fiberglass core rod 12, and a polymer filling layer 17 is fixedly connected to the outer wall of the epoxy fiberglass cylinder 16. A silicone rubber skirt 18 is wrapped around the outer wall of the polymer filling layer 17. Several first valve plates 13 are fixedly installed on the outer wall of the epoxy fiberglass core rod 12. The epoxy fiberglass cylinder 16 and the epoxy fiberglass core rod 12 are connected by a wrapping connection, and the epoxy fiberglass cylinder 16 is made of epoxy resin material. The polymer filling layer 17 is tightly bonded to both the epoxy fiberglass cylinder 16 and the silicone rubber skirt 18, and the polymer filling layer 17 is made of polyimide material.

[0028] After the staff places the lightning protection device body 1 in the required position, they manually insert the ground spikes 11 through the base 10 into the ground to ensure a good electrical connection between the lightning protection device body 1 and the ground, providing a path for the discharge of lightning current. When lightning strikes the lightning rod 2, the lightning current is first introduced into the lightning protection device body 1 through the lightning rod 2. The design of the lightning rod 2 allows it to preferentially attract lightning, thereby protecting surrounding buildings or equipment from direct lightning strikes. The lightning current then flows along the lightning rod 2 through the mounting base 6 and the lead pipe 7, and is safely discharged into the ground through the ground spikes 11 inside the base 10, achieving effective discharge of the lightning current. The epoxy fiberglass core rod 12 serves as the core conductive part, responsible for conducting the lightning current. Several first valve plates 13 fixed on its outer wall play a voltage limiting role during overvoltage, preventing lightning from passing through. When the current causes a breakdown in the lightning protection device, the epoxy fiberglass cylinder 16, wrapped around the outer wall of the epoxy fiberglass core rod 12, forms the first layer of insulation protection. Made of epoxy resin, this first layer has excellent insulation properties and mechanical strength. A polymer filling layer 17, filled between the epoxy fiberglass cylinder 16 and the silicone rubber skirt 18, provides additional insulation and mechanical support. The polymer filling layer 17, made of polyimide, has excellent heat resistance, chemical corrosion resistance, and electrical insulation properties, ensuring the long-term stable operation of the lightning protection device in harsh environments. Meanwhile, the silicone rubber skirt 18 serves as the outermost layer of protection. Silicone rubber has excellent arc resistance, which can quickly extinguish the arc after a lightning strike, preventing line tripping or equipment damage. This multi-chamber gap-coordinated operation lightning protection device achieves breakdown resistance and high-efficiency lightning protection.

[0029] Example 2: The multi-chamber gap coordinated operation lightning protection device for breakdown resistance disclosed in this example discloses the following technical content, which facilitates the guidance and dispersion of lightning by the multi-chamber gap coordinated operation lightning protection device. See attached document for details. Figure 1 - Appendix Figure 4 and attached Figure 6 The lightning rod 2 and the lead pipe 7 are connected, and the lightning rod 2 and the upper lightning protection ball 3 are tightly fitted together. The upper lightning protection ball 3 has a first cavity inside, and multiple second valve plates 14 are arranged inside the first cavity. Each second valve plate 14 is located on the outer wall of the epoxy fiberglass core rod 12. The lower lightning protection ball 5 has a second cavity inside, and multiple third valve plates 15 are arranged inside the second cavity. Each third valve plate 15 is located on the outer wall of the epoxy fiberglass core rod 12.

[0030] The lightning rod 2 is tightly fitted with the upper lightning protection ball 3 and the lower lightning protection ball 5. Both the upper lightning protection ball 3 and the lower lightning protection ball 5 have cavities inside, and multiple second valve plates 14 and third valve plates 15 are respectively installed in the cavities. The multiple second valve plates 14 and third valve plates 15 are located on the outer wall of the epoxy fiberglass core rod 12, forming a multi-chamber structure. When lightning strikes the lightning rod 2 directly, the lightning flows through the lightning rod 2 into the cavities opened in the upper lightning protection ball 3 and the lower lightning protection ball 5. The multiple second valve plates 14 and third valve plates 15 in the cavities will play a voltage limiting role during overvoltage, which can disperse the lightning energy and prevent the lightning current from breaking down the lightning protection device. This realizes the multi-chamber gap collaborative operation type lightning protection device to guide and disperse lightning, which not only improves the lightning protection performance, but also further resists breakdown.
