Description

Technical Field

[0001] This utility model relates to the field of magnetically shielded reactor technology, specifically to a reactor with a magnetically shielded structure. Background Technology

[0002] Reactors, as crucial components in power systems, transmission and distribution equipment, and various power electronic devices, are primarily used to limit short-circuit currents, suppress harmonics, and compensate reactive power. During operation, the reactor's core and windings generate strong alternating magnetic fields. If left uncontrolled, these fields can cause electromagnetic interference to surrounding metal components, control circuits, and electronic devices, and may also lead to additional eddy current losses and localized heating, reducing the overall system efficiency and operational stability. Especially in high-voltage, high-power, or compact environments, the reactor's leakage flux distribution is wide, and magnetic field leakage can degrade the performance of nearby equipment, even causing signal distortion and malfunctions. Therefore, to mitigate the impact of magnetic field leakage, magnetic shielding structures are typically introduced in engineering. These structures effectively guide and suppress the reactor's external magnetic flux path, reducing the intensity of the magnetic field radiated into space, thereby improving the equipment's electromagnetic compatibility and safety. However, existing magnetic shielding structures often suffer from high manufacturing costs, large installation space requirements, or insufficient shielding efficiency, making it difficult to simultaneously achieve both structural compactness and shielding effectiveness. This significantly limits the application of reactors in high-density electrical equipment.

[0003] Current magnetic shielding methods for reactors mostly employ metal shielding shells or high-permeability material plates. While these methods can reduce magnetic leakage to some extent, they often increase the weight and manufacturing complexity of the equipment. Furthermore, during long-term operation, the shielding material may degrade in performance due to temperature rise, mechanical vibration, or environmental corrosion, leading to a weakening of the shielding effect. In addition, in space-constrained installation environments, large shielding shells not only affect the layout of heat dissipation channels but may also increase airflow resistance, reducing the reactor's heat dissipation efficiency and potentially causing temperature rise and insulation aging. On the other hand, some magnetic shielding designs fail to fully consider the magnetic field distribution characteristics of the reactor under different operating conditions, resulting in uneven shielding effects under certain conditions, or even the counterproductive effect of localized magnetic field enhancement. To address these issues, there is an urgent need for a reactor magnetic shielding technology with a reasonable structural design, high shielding efficiency, and minimal impact on heat dissipation and installation, in order to effectively control magnetic leakage and ensure the safety, stability, and efficiency of the reactor and its surrounding equipment during long-term operation.

[0004] In view of the above, in order to overcome the above technical problems, this utility model designs a reactor with a magnetic shielding structure, thus solving the above technical problems. Utility Model Content

[0005] The technical objective of this invention is to design a reactor magnetic shielding technology with a reasonable structural design, high shielding efficiency, and minimal impact on heat dissipation and installation, so as to effectively control leakage flux and ensure the safety, stability, and efficiency of the reactor and its peripheral equipment during long-term operation.

[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution: The reactor equipped with a magnetic shielding structure includes components such as a base, mounting box, iron core wire assembly, mounting block, mounting pole, connecting block, fixing block, fixing pole, controller, shielding plate, first shielding block, second shielding block, and top cover. The base is fixedly mounted on the ground, supporting the entire reactor and maintaining stability to ensure the equipment does not tilt or shift during operation. The mounting box is installed above the base, supporting and fixing the iron core wire assembly, and providing the basic structural support for the reactor. The iron core wire assembly is installed in a linear array above the mounting box; its optimized arrangement achieves electromagnetic performance optimization and creates a stable magnetic field distribution during operation. The connecting block is installed above the mounting box, connecting the controller and other components of the reactor, and also serves for load-bearing and positioning. The controller is fixedly installed above the connecting block, used to monitor and control the reactor's operating status.

[0007] The shielding plate is installed on the side of the iron core wire assembly to effectively shield externally leaked magnetic fields and reduce electromagnetic interference to surrounding equipment. The first shielding block is installed along the front-to-back direction of the shielding plate, and the second shielding block is installed along the left-to-right direction of the shielding plate. Together, they form a three-dimensional shielding structure to achieve an all-around magnetic field suppression effect. The top cover is installed above the connecting plate to provide top sealing protection for the reactor and prevent top magnetic leakage. To enhance safety and aesthetics, the edges of the shielding plate and the top cover are rounded, reducing the risk of injury during operation and optimizing airflow and heat dissipation channels, which is beneficial to the long-term stable operation of the reactor. This structure, through the coordinated layout of the base, mounting box, iron core wire assembly, shielding plate, and shielding blocks, achieves a comprehensive effect of stable support, efficient magnetic field shielding, and convenient control.

[0008] The mounting box has an internal cavity for accommodating and securing internal components, while also providing space for the shielding structure. Multiple shielding spheres are placed within this cavity. These spheres effectively absorb and disperse the magnetic field generated by the core wire assembly during reactor operation, reducing leakage flux and improving electromagnetic compatibility. The shielding spheres are arranged in a rectangular array, closely and uniformly, ensuring a uniform magnetic field distribution throughout the mounting cavity through a rational spatial layout, thereby maximizing the shielding effect. This design not only reduces electromagnetic interference to external equipment but also optimizes the internal magnetic field path, improving the reactor's operational stability and safety, while maintaining the compact and orderly internal structure of the mounting box, facilitating subsequent maintenance and repair.

[0009] Mounting blocks are installed at the top and bottom of the sides of the core wire assembly to fix it and provide stable support, ensuring that the core wire assembly does not shift or shake during operation. A vertical mounting rod is positioned between the two mounting blocks, working in conjunction with the mounting blocks to further enhance the structural stability of the core wire assembly and ensure its good mechanical strength and reliability during long-term operation. Fixing blocks are installed at both ends of the connecting block to fix the relative position of the connecting block and surrounding structural components, ensuring the stable layout of the entire reactor assembly. A fixing rod is positioned between the two fixing blocks on the same side, forming a support frame with the fixing blocks. This enhances the load-bearing capacity and seismic performance of the connecting block, thereby ensuring the structural integrity of the equipment while effectively reducing the risk of displacement due to vibration or external forces, ensuring that the reactor can stably and efficiently perform its electrical performance during operation.

[0010] The first shielding block has a crescent-shaped cross-section, which helps to effectively guide and disperse leakage magnetic field in the front-back direction, reducing the interference of the magnetic field on surrounding equipment. The second shielding block has a wavy shape, which enhances the damping effect of magnetic flux through its tortuous contour design and further suppresses the diffusion of leakage magnetic field in the left-right direction. Together with the first shielding block, they form a three-dimensional shielding structure, enabling comprehensive and effective control of the magnetic field generated by the reactor, thereby improving the overall electromagnetic compatibility performance and equipment operation stability.

[0011] The shielding plate comprises several components, including a snap-fit ​​groove, a snap-fit ​​block, a conductive gasket, a mating block, and a shielding strip. These components work together to form a complete shielding structure. The snap-fit ​​groove is located on the inner edge of the shielding plate and engages with the snap-fit ​​block to reliably fix and securely connect the shielding plate to other components, ensuring that the shielding plate will not shift or loosen during operation. The snap-fit ​​block is adjacent to the snap-fit ​​groove, enhancing structural stability through mechanical interlocking and providing mounting support for the conductive gasket. The conductive gasket is mounted on the side of the snap-fit ​​block, effectively guiding and dissipating current in the shielding plate and reducing electromagnetic interference. The mating block is mounted on the inner surface of the shielding plate, adjusting and fixing the gap between the shielding plate and the core wire assembly or other components, ensuring a reasonable spatial arrangement between the shielding plate and the internal magnetic field source. The shielding strip is located on the inner surface of the shielding plate, covering and guiding magnetic flux to further suppress leakage magnetic flux, thereby improving the overall electromagnetic compatibility performance and operational stability of the reactor.

[0012] The shielding plate is constructed from a combination of materials to fully leverage the advantages of different materials in magnetic shielding and structural performance. The inner side of the shielding plate is made of permalloy, a material with high magnetic permeability and excellent magnetic shielding properties, effectively guiding and absorbing the magnetic field generated by the reactor core wires, thereby reducing the impact of leakage magnetic field on surrounding equipment. The outer side of the shielding plate is made of silicon steel, which possesses excellent mechanical strength and heat resistance, providing a stable support structure for the shielding plate while enhancing the overall durability and vibration resistance of the equipment. Furthermore, the inner surface of the shielding plate is treated with a conductive coating, which effectively guides inrush current and additional current, further reducing electromagnetic interference and improving shielding efficiency. This combined material structure not only optimizes the division of functions between the inner and outer sides but also enhances the mechanical stability and long-term operational reliability of the shielding plate while ensuring magnetic shielding effectiveness, thus guaranteeing the efficient and safe operation of the reactor.

[0013] The shielding strip is angled and positioned on the inner side of the shielding plate. This angled arrangement effectively alters the propagation path of leakage magnetic field, dispersing and attenuating the magnetic field generated by the reactor during conduction, thereby improving the overall shielding effect. The shielding strip is made of ferrite absorbing material, which possesses excellent high-frequency magnetic field absorption performance and superior electromagnetic wave attenuation capability. It can absorb and dissipate some magnetic energy during reactor operation, effectively reducing interference from leakage magnetic field to surrounding electronic equipment and control circuits. Simultaneously, the low-loss characteristics of ferrite material ensure that the shielding strip maintains stable performance under long-term high-power operation, and is not prone to failure due to temperature rise or magnetic saturation. The angled shielding strip, in conjunction with the shielding plate, shielding blocks, and other shielding structures, forms a comprehensive, multi-layered magnetic field suppression system, significantly improving the reactor's electromagnetic compatibility performance and operational safety, ensuring stable and efficient operation of the equipment in complex electromagnetic environments.

[0014] The beneficial effects of this utility model are as follows: (1) This utility model achieves effective control of magnetic leakage generated by the iron core wire group by setting a shielding structure such as a shielding plate, a first shielding block, a second shielding block, and an inclined shielding strip in the reactor. The shielding plate is made of composite materials, with permalloy on the inner side and silicon steel on the outer side, and a conductive coating is applied to the inner side. It can simultaneously perform magnetic conduction, wave absorption, and conductivity functions, thereby reducing the interference of magnetic field leakage to surrounding equipment. The first shielding block and the second shielding block respectively guide and suppress the magnetic leakage in the front-back and left-right directions. Combined with the inclined ferrite wave absorbing shielding strip, it achieves an all-round and multi-layered magnetic leakage shielding effect, which makes the reactor have higher electromagnetic compatibility and stability during operation, and at the same time improves the overall safety and reliability of the equipment.

[0015] (2) The shielding structure design of this utility model takes into account both structural compactness and ease of installation. The corners of the shielding plate and the top cover are rounded, which not only enhances operational safety but also optimizes the heat dissipation channel, which is beneficial to the thermal management of the equipment during high-power operation. The mounting blocks, mounting rods, fixing blocks and fixing rods and other components work together to support the iron core wire group and the shielding structure, ensuring overall layout stability and strong vibration resistance, and reducing mechanical stress and the risk of displacement that may occur during long-term operation. Through the above technical measures, the reactor not only significantly improves its performance in terms of leakage flux suppression, but also maintains good structural stability and efficient electrical performance during long-term operation, meeting the application requirements of high-density power equipment and complex electromagnetic environments.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-5 As shown, a reactor with a magnetic shielding structure includes a base 1, a mounting box 2, a core wire assembly 5, a mounting block 6, a mounting vertical rod 7, a connecting block 8, a fixing block 9, a fixing rod 10, a controller 11, a shielding plate 12, a first shielding block 13, a second shielding block 14, and a top cover 15. The base 1 is fixedly mounted on the ground, supporting the entire reactor and maintaining stability to ensure the equipment does not tilt or shift during operation. The mounting box 2 is mounted above the base 1, supporting and fixing the core wire assembly 5, and providing the basic structural support for the reactor. The core wire assembly 5 is mounted in a linear array above the mounting box 2, optimizing the reactor's electromagnetic performance through proper arrangement and forming a stable magnetic field distribution during operation. The connecting block 8 is mounted above the mounting box 2, connecting the controller 11 and other components of the reactor, and also serving a load-bearing and positioning function. The controller 11 is fixedly mounted above the connecting block 8, used to monitor and control the reactor's operating status.

[0021] The shielding plate 12 is installed on the side of the iron core wire group 5 to effectively shield externally leaked magnetic fields and reduce electromagnetic interference to surrounding equipment. The first shielding block 13 is installed along the front-back direction of the shielding plate 12, and the second shielding block 14 is installed along the left-right direction of the shielding plate 12. Together, they form a three-dimensional shielding structure to achieve an all-round magnetic field suppression effect. The top cover 15 is installed above the connecting plate to provide top sealing protection for the reactor and prevent top magnetic leakage. To enhance safety and aesthetics, the edges of the shielding plate 12 and the top cover 15 are rounded, which reduces the risk of injury during operation and optimizes the airflow heat dissipation channel, which is conducive to the long-term stable operation of the reactor. This structure, through the coordinated layout of the base 1, mounting box 2, iron core wire group 5, shielding plate 12, and shielding blocks, achieves a comprehensive effect of stable support, efficient magnetic field shielding, and convenient control.

[0022] The mounting box 2 has an internal mounting cavity 3 for accommodating and fixing internal components, while also providing space support for the shielding structure. Multiple shielding spheres 4 are placed within the mounting cavity 3. These spheres 4 effectively absorb and disperse the magnetic field generated by the iron core wire group 5 during reactor operation, reducing leakage flux and improving electromagnetic compatibility. The shielding spheres 4 are arranged in a rectangular array, closely and uniformly, ensuring a uniform magnetic field distribution throughout the mounting cavity 3 through a reasonable spatial layout, thereby maximizing the shielding effect. This design not only reduces electromagnetic interference to external equipment but also optimizes the internal magnetic field path, improving the reactor's operational stability and safety, while maintaining the compact and orderly internal structure of the mounting box 2, facilitating subsequent maintenance and repair operations.

[0023] Mounting blocks 6 are installed at the upper and lower ends of the sides of the core wire assembly 5 to fix the core wire assembly 5 and provide stable support, while ensuring that the position of the core wire assembly 5 will not shift or shake during operation. A mounting vertical rod 7 is provided between the upper and lower mounting blocks 6. The mounting vertical rod 7 works in conjunction with the mounting blocks 6 to further enhance the structural stability of the core wire assembly 5 and ensure that it maintains good mechanical strength and reliability during long-term operation. Fixing blocks 9 are installed at the left and right ends of the connecting block 8 to fix the relative position of the connecting block 8 and the surrounding structural components, ensuring the stable layout of the overall reactor assembly. A fixing rod 10 is provided between the two fixing blocks 9 on the same side. The fixing rod 10 and the fixing blocks 9 together form a support frame, improving the load-bearing capacity and seismic performance of the connecting block 8. This ensures the structural integrity of the equipment while effectively reducing the risk of displacement caused by vibration or external forces, ensuring that the reactor can stably and efficiently perform its electrical performance during operation.

[0024] like Figure 2 As shown, the cross-sectional shape of the first shielding block 13 is set to crescent shape. This structure helps to effectively guide and disperse leakage magnetic field in the front-back direction, reducing the interference of the magnetic field on surrounding equipment. The shape of the second shielding block 14 is set to wave shape. The tortuous contour design enhances the damping effect of magnetic flux and further suppresses the diffusion of leakage magnetic field in the left-right direction. Thus, together with the first shielding block 13, a three-dimensional shielding structure is formed, realizing the all-round effective control of the magnetic field generated by the reactor, improving the overall electromagnetic compatibility performance and equipment operation stability.

[0025] like Figure 5As shown, the shielding plate 12 includes multiple components such as a snap-fit ​​groove 121, a snap-fit ​​block 122, a conductive pad 123, a mating block 124, and a shielding strip 125, which work together to form a complete shielding structure. The snap-fit ​​groove 121 is located at the edge of the inner side of the shielding plate 12 and is used to cooperate with the snap-fit ​​block 122 to reliably fix and securely connect the shielding plate 12 to other components, ensuring that the shielding plate 12 will not shift or loosen during operation. The snap-fit ​​block 122 is arranged adjacent to the snap-fit ​​groove 121, improving the stability of the structure through mechanical fitting, and providing installation support for the conductive pad 123. The conductive pad 123 is installed on the side of the snap-fit ​​block 122, effectively guiding and dissipating the current in the shielding plate 12 and reducing electromagnetic interference. The mating block 124 is installed on the inner side of the shielding plate 12 and is used to adjust and fix the gap between the shielding plate 12 and the iron core wire group 5 or other components, ensuring that the shielding plate 12 maintains a reasonable spatial arrangement with the internal magnetic field source. The shielding strip 125 is disposed on the inner side of the shielding plate 12. By covering and guiding the magnetic flux, it further suppresses leakage magnetic flux, thereby improving the overall electromagnetic compatibility performance and operational stability of the reactor.

[0026] The shielding plate 12 is constructed from a combination of materials to fully leverage the advantages of different materials in magnetic shielding and structural performance. The inner side of the shielding plate 12 is made of permalloy, a material with high magnetic permeability and excellent magnetic shielding performance, effectively guiding and absorbing the magnetic field generated by the reactor core wire group 5, thereby reducing the impact of leakage magnetic field on surrounding equipment. The outer side of the shielding plate 12 is made of silicon steel, which possesses excellent mechanical strength and heat resistance, providing a stable support structure for the shielding plate 12 while enhancing the overall durability and vibration resistance of the equipment. Furthermore, the inner surface of the shielding plate 12 is treated with a conductive coating, which effectively guides inrush current and additional current, further reducing electromagnetic interference and improving shielding efficiency. This combined material structure not only optimizes the division of functions between the inner and outer sides but also enhances the mechanical stability and long-term operational reliability of the shielding plate 12 while ensuring magnetic shielding effectiveness, thus guaranteeing the efficient and safe operation of the reactor.

[0027] like Figure 5As shown, the shielding strip 125 is inclinedly arranged on the inner side of the shielding plate 12. This inclined arrangement effectively alters the propagation path of leakage magnetic flux, dispersing and attenuating the magnetic field generated by the reactor during conduction, thereby improving the overall shielding effect. The shielding strip 125 is made of ferrite absorbing material, which possesses excellent high-frequency magnetic field absorption performance and superior electromagnetic wave attenuation capability. It can absorb and dissipate some magnetic energy during reactor operation, effectively reducing interference from leakage magnetic flux to surrounding electronic equipment and control circuits. Simultaneously, the low-loss characteristics of ferrite material ensure that the shielding strip 125 maintains stable performance under long-term high-power operation, and is not prone to failure due to temperature rise or magnetic saturation. The inclined shielding strip 125, together with the shielding plate 12, shielding blocks, and other shielding structures, forms a comprehensive, multi-layered magnetic field suppression system, significantly improving the electromagnetic compatibility performance and operational safety of the reactor, ensuring stable and efficient operation of the equipment in complex electromagnetic environments.

[0028] In operation, the reactor's core wire group 5 generates a magnetic field when current flows through it. This magnetic field creates a stable inductance within the reactor, but may also leak magnetic flux into the surrounding space. The shielding plate 12, the first shielding block 13, the second shielding block 14, and the inclined shielding strip 125, all positioned on the sides of the core wire group 5, work together to guide, absorb, and suppress the magnetic field. Specifically, the permalloy inner side of the shielding plate 12 efficiently absorbs and guides magnetic flux, while the silicon steel outer side provides structural support and additional magnetic shielding. The conductive coating guides inrush current and reduces high-frequency interference. The first shielding block 13 and the second shielding block 14 locally disperse and guide leakage magnetic flux in the front-back and left-right directions, respectively. The inclined ferrite absorbing shielding strip 125 further absorbs high-frequency magnetic energy and attenuates leakage magnetic signals, thereby achieving comprehensive, multi-layered magnetic field suppression.

[0029] During this process, components such as base 1, mounting box 2, mounting block 6, mounting vertical rod 7, fixing block 9, and fixing rod 10 work together to ensure the stable arrangement of the iron core wire group 5 and the shielding structure, preventing displacement or loosening of the magnetic shielding structure during operation. Simultaneously, the rounded corner design of the shielding plate 12 and top cover 15 not only reduces operational risks but also optimizes airflow and heat dissipation channels, ensuring effective thermal management of the reactor under high power or long-term operation. Through the combination of the above structures and materials, this invention effectively reduces magnetic leakage, improves the electromagnetic compatibility performance and operational safety of the reactor, and ensures long-term stable operation of the equipment in complex electromagnetic environments.
