Description

Technical Field

[0001] This utility model relates to the field of electrical lightning protection equipment technology, specifically to a detachable electrical equipment lightning protection device. Background Technology

[0002] Electrical equipment is a widely used type of power equipment, such as distribution cabinets and transformers. Power equipment is used for the management of power systems and is generally installed outdoors, making it easily affected by thunderstorms. Therefore, it is necessary to do a good job of lightning protection. The most common and effective way to protect against lightning is by grounding. The lightning protection structure mainly consists of lightning rods, wiring harnesses, and buried terminals.

[0003] Currently, electrical equipment is typically sealed for rain and moisture protection. While this protects internal components, it hinders the installation and connection of lightning protection structures, making installation and maintenance inconvenient. Current lightning protection devices cannot be quickly disassembled from electrical equipment, resulting in unsatisfactory assembly convenience. Furthermore, they cannot meet the needs of different electrical devices for lightning protection and maintenance, presenting certain drawbacks. Additionally, current lightning rods are generally directly fixed to the lightning protection device and cannot be assembled separately. However, in actual use, lightning rods are exposed to harsh environments such as wind and rain, and are prone to breakage in strong winds, leading to a short lifespan. When a lightning rod fails, the entire device must be replaced, resulting in high costs and inconvenience in assembling the entire lightning protection system. Therefore, improvements are needed.

A first screw hole is opened on both sides of the side plate, which extends to the positioning cavity groove, and a first positioning screw is installed in the first screw hole.

[0011] Furthermore, a second screw hole extending through to the cable hole is provided on the side of the cable tube, and a second positioning screw is installed in the second screw hole;

[0012] Furthermore, the mounting plate is fixed to the electrical equipment by a mounting rod;

[0017] Furthermore, each of the plurality of second positioning blocks is provided with a positioning protrusion on one side, and the positioning protrusion is adapted to the positioning groove.

[0018] The above technical solution has the following advantages or beneficial effects:

[0019] This utility model provides a detachable lightning protection device for electrical equipment. By incorporating components such as a detachable surge arrester assembly, a quick-positioning mechanism, a protective box, an insulating base plate, and an insulating mounting seat, when the lightning rod body is broken due to human error or force majeure, only the corresponding lightning rod body needs to be replaced, eliminating the need to replace the entire lightning protection device. This reduces costs and saves money. The lightning rod body can be flexibly assembled onto the insulating base plate, facilitating easy assembly and disassembly. When replacing the lightning rod body, the old lightning rod body is rotated, causing the insulating mounting seat to detach from the circular base, thus separating the two electrical terminals. The new lightning rod body is then assembled onto the insulating base plate, facilitating the overall transportation and on-site installation of the lightning rod body. This provides excellent flexibility and ease of use. Furthermore, the quick-positioning mechanism between the mounting plate and the detachable surge arrester assembly enables both the positioning and removal of the detachable surge arrester assembly, facilitating the installation and maintenance of the lightning protection device on electrical equipment.

[0020] Furthermore, by installing a removable protective box on the outside of the electrical equipment, and a spiral spring installed on the inside of the protective box, the conductive wire harness can be wound up and its length adjusted, so that the entire device can meet the installation and use on different electrical equipment. Through detachable assembly, it can also be conveniently installed and used on different electrical equipment. It has strong versatility, is easy to disassemble and install, and is convenient to maintain. It has good flexibility and is beneficial to practical use.

[0021] Furthermore, the combined use of the hook and the positioning cavity makes the installation process of the lightning protection device and electrical equipment simple and quick. Workers only need to align the hook with the positioning cavity and insert it for installation, without complicated fixing steps or tools, which greatly improves installation efficiency. When it is necessary to disassemble the lightning protection device, it is also convenient and quick to remove the hook from the positioning cavity. This design facilitates operation when it is necessary to maintain, replace or upgrade the lightning protection device, reducing downtime and maintenance costs.

[0022] Furthermore, the first screw holes and the first positioning screws on both sides of the side plate provide additional fastening force for the connection between the hook and the positioning cavity. This mechanical locking method ensures the stable installation of the lightning protection device on the electrical equipment, and it is not easy to loosen or fall off even in harsh environments or under vibration conditions, thereby improving the overall stability and safety of the device. Similarly, the second screw holes and the second positioning screws on the side of the cable tray play a key role in fixing the cables inside the cable tray. It ensures the stable position of the cables in the cable tray holes and prevents the cables from shifting or being damaged due to vibration or external forces, further ensuring the reliability and safety of the electrical connection.

[0023] Furthermore, by placing the windproof casing outside the lightning rod body, the direct impact of wind on the lightning rod body can be effectively reduced, decreasing vibration and displacement caused by wind. This ensures that the lightning rod body can function stably and accurately in lightning environments. A stable lightning rod body can more effectively guide lightning current through the grounding system for safe discharge, improving lightning protection. Secondly, it also provides a certain degree of protection, preventing rainwater, dust, and other external factors from directly eroding the lightning rod body, extending its service life, and reducing safety hazards caused by bird nests, debris accumulation, etc. In addition, when the lightning rod body needs to be inspected or replaced, workers can more easily approach it without worrying about external environmental interference or safety hazards.

[0024] Furthermore, during assembly, the insulating mounting base at the bottom of the lightning rod body is threaded onto the circular base, allowing the first electrical terminal to extend through the cavity on the insulating mounting base to the second electrical terminal. The cavity provides a channel for the first electrical terminal to extend safely and stably to the second electrical terminal and achieve electrical connection with the lightning rod body. This design ensures the continuity and reliability of the electrical connection and reduces the risk of electrical failures caused by poor contact or loosening.

[0025] Furthermore, by setting the positioning protrusion and positioning groove to match, the second positioning block can be quickly and accurately installed on the first positioning block, so that the detachable surge arrester assembly can be detachably installed on the quick positioning mechanism. This makes it easy to disassemble during use, greatly simplifies the installation process, reduces installation time, and improves work efficiency. Attached Figure Description
