[0002] A winding structure refers to a set of turns of wire that constitute the electrical circuit corresponding to a specific voltage value marked on a transformer. The basic unit of a winding is a coil, which is usually composed of multiple turns of wire, but can also be composed of a single turn. Multiple coils are combined together to form a winding, which is arranged in a specific way within the iron core and wound around the core posts to form a closed magnetic circuit system.

[0022] 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.

[0023] Please see Figures 1-6 As shown, a winding structure for reducing electromagnetic noise includes a winding tube 1, which serves as the foundation of the winding structure and provides a stable support structure for the functional coil 3. Noise-reducing cotton tubes 2 are installed inside the winding tube 1. The noise-reducing cotton material is selected for its excellent sound absorption and heat resistance properties to ensure stable noise reduction even under long-term high-load operation. The functional coil 3, the core part of the winding structure, is wound around the outside of the winding tube 1 and is responsible for generating or transmitting electromagnetic energy. A protective jacket 4 is fitted over the functional coil 3, primarily to protect it from damage caused by the external environment. Fixed baffles 5 of different specifications are installed at both ends of the winding tube 1. These baffles not only fix the position of the functional coil 3 to prevent it from moving or deforming during operation, but also allow for quick and convenient disassembly and assembly through their internal disassembly and assembly structure 6, facilitating maintenance and replacement. The internal design of the disassembly and assembly structure 6 on the fixed baffle 5 not only improves the convenience of maintenance but also reduces the cost and time of replacing damaged parts.

[0024] The outer side of the winding shaft tube 1 is designed with a coil storage groove. The shape and size of the coil storage groove are customized according to the specifications of the functional coil 3 to ensure that the coil can be tightly and evenly attached to the winding shaft tube 1, thereby improving the electromagnetic conversion efficiency. This design makes the winding of the functional coil 3 more orderly and stable. The coil storage groove is evenly provided with sound guide holes around its perimeter. Its main function is to help reduce noise. When the electromagnetic wire is running, the noise generated will be more effectively absorbed and isolated by the noise reduction cotton tube 2 through the sound guide holes. The design of the sound guide holes needs to take into account the noise propagation path and the sound absorption performance of the noise reduction cotton tube 2 to ensure the best noise reduction effect. The noise reduction cotton tube 2 is slidably snapped into the inside of the winding shaft tube 1. This connection method not only facilitates installation and disassembly, but also ensures a tight contact between the noise reduction cotton tube 2 and the winding shaft tube 1. The functional coil 3 is tightly wound on the outer surface of the winding shaft tube 1. Tight winding can ensure that the electromagnetic induction between the coils is more uniform and efficient, thereby improving the performance of the entire winding structure.

[0025] The functional coil 3 includes a functional core 301 and an insulating tube 302. The functional core 301 is located at the center of the functional coil 3. In the winding structure, the functional core 301 is positioned at the center of the functional coil 3 to ensure stable transmission and efficient utilization of electromagnetic energy. The material and specifications of the functional core 301 are usually selected according to specific application requirements to meet the requirements of electromagnetic performance and durability. The insulating tube 302 wraps around the outer surface of the functional core 301. Since the functional core 301 may generate high temperatures or electromagnetic interference during operation, the insulating tube 302 is made of fire-resistant and heat-insulating materials to ensure stability and safety even under extreme conditions. In addition, the insulating tube 302 also... It can effectively prevent the functional core 301 from directly contacting the external environment, extending its service life. The isolation tube 302 is made of fireproof and heat-insulating material. The isolation tube is uniformly designed with hexagonal vent holes around its perimeter. When the functional coil 3 is running, it will generate a certain amount of heat. The hexagonal vent holes can help dissipate the heat more quickly, preventing the performance from deteriorating or being damaged due to excessive temperature. At the same time, the vent holes can also increase air circulation, which helps to reduce electromagnetic interference and noise. The design of the hexagonal vent holes not only improves heat dissipation performance and air circulation efficiency, but also enhances the mechanical strength of the isolation tube 302. Compared with round or other shaped holes, hexagonal holes have better structural stability and resistance to deformation while maintaining the same area.

[0026] The protective jacket 4 tightly covers the outside of the functional coil 3. The main function of the protective jacket 4 is to provide additional protection and isolation to ensure that the functional coil 3 remains stable and safe in harsh environments or during long-term operation. It fits tightly against the outer surface of the functional coil 3 to prevent damage to the functional coil 3 from the external environment, such as moisture, corrosion, mechanical impact, etc. The protective jacket 4 is made of heat-resistant and breathable material. The heat-resistant material ensures that the protective jacket 4 will not melt, deform or lose its protective function at high temperatures, thereby protecting the internal functional coil 3 from damage. At the same time, the design of the breathable material helps heat dissipation and gas circulation, preventing performance degradation or damage caused by heat accumulation.

[0027] The disassembly and assembly structure 6 includes a connecting block 601, which is responsible for connecting the fixed baffle 5 and the winding shaft tube 1. The connecting block 601 is uniformly welded to the inner side of the fixed baffle 5. The two ends of the winding shaft tube 1 are uniformly provided with mounting slots. The connecting block 601 is slidably engaged in the inside of the mounting slot. The outer side of the mounting slot is provided with a fixing threaded hole, which passes through the connecting block 601. The inside of the fixing threaded hole is connected with a fixing bolt 602, which is used to fix the connecting block 601 in the mounting slot, thereby ensuring a stable connection between the fixed baffle 5 and the winding shaft tube 1. The outer side of the fixing threaded hole is designed with a fixing storage groove. One end of the fixing bolt 602 is stored inside the fixing storage groove. After the fixing bolt 602 is installed, its excess part can be stored inside the fixing storage groove to avoid safety hazards caused by protrusion or loosening.
