Description

Technical Field

[0001] This invention belongs to the field of electronic equipment technology and relates to a reactor. Background Technology

[0002] Reactors typically consist of a coil and an iron core forming an electromagnetic device with predetermined inductance characteristics. To adjust the magnetic reluctance of the magnetic circuit and reduce the possibility of the iron core entering magnetic saturation, some reactors employ a structure where multiple iron core units are stacked axially, with gaps between adjacent units to form an air gap. During transportation, installation, and operation, reactors may be subjected to external vibrations, impacts, and alternating electromagnetic forces, causing relative movement between the iron core units or changes in the relative position between the inner iron core and adjacent magnetically conductive components. These positional changes can cause fluctuations in the air gap size or magnetic circuit state, leading to changes in magnetic reluctance and causing the reactor's inductance to deviate from its predetermined value. Especially in operating scenarios where high inductance parameter stability is required, inductance fluctuations can also affect the operating state of the circuit containing the reactor. Therefore, existing reactors suffer from the problem of difficulty in maintaining stable inductance under vibration and alternating electromagnetic forces. Summary of the Invention

[0003] The present invention provides a reactor to solve the problem that existing reactors have difficulty maintaining stable inductance under vibration and alternating electromagnetic forces.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A reactor includes a coil, an inner iron core disposed within the coil, and a magnetic plate disposed at a distance from one end of the inner iron core. An elastic buffer assembly is provided between the inner iron core and the magnetic guide plate. One side of the elastic buffer assembly is connected to the inner iron core and the other side is connected to the magnetic guide plate, so that the inner iron core can float elastically relative to the magnetic guide plate. An adaptive magnetic guiding component is also provided between the inner iron core and the magnetic guiding plate. The adaptive magnetic guiding component includes a support member connected to the magnetic guiding plate and a magnetic guiding body movably connected to the support member. The magnetic guiding body is magnetically engaged with the inner iron core and the magnetic guiding plate respectively, and can move relative to the support member as the inner iron core floats, so as to maintain the magnetic path between the inner iron core and the magnetic guiding plate. The inner core includes multiple core modules stacked sequentially along the axial direction of the inner core, an insulating spacer disposed between adjacent core modules, and a fixing structure connecting the multiple core modules. An air gap is formed between adjacent core modules through the insulating spacer.

[0005] Furthermore, the fixing structure includes a threaded tie rod made of a non-magnetic insulating material and a nut that mates with the threaded tie rod. The threaded tie rod is sequentially inserted into multiple core modules along the axial direction of the inner core. The nut is threadedly connected to the threaded tie rod and abuts against the core module located at the axial end of the inner core to press the multiple core modules together along the stacking direction of the core modules.

[0006] Furthermore, the elastic buffer assembly includes an elastic support ring made of a non-magnetic insulating elastic material, the elastic support ring being arranged around the axis of the inner iron core, the elastic support ring being connected to the inner iron core on one side along the axial direction of the inner iron core, and the other side being connected to the magnetic plate.

[0007] Furthermore, the adaptive magnetic conductive components are configured in multiple groups, and the multiple groups of adaptive magnetic conductive components are arranged at circumferential intervals along the inner iron core.

[0008] Furthermore, the support includes a frame and an elastic connector. The frame is fixedly connected to the magnetic plate, the elastic connector is connected to the frame, and the magnetic conductor is rotatably connected to the elastic connector so that the magnetic conductor can swing relative to the frame.

[0009] Furthermore, the elastic connector includes a rigid support and an elastic strip connecting the frame and the rigid support. One end of the elastic strip is connected to the frame, and the other end is connected to the rigid support. A rotating shaft is provided on the magnetic conductor, and the rotating shaft is inserted into the rigid support and rotatably connected to the rigid support.

[0010] Furthermore, the magnetic conductor has a first end facing the inner iron core and a second end facing the magnetic plate; When the coil is energized, the first end contacts the inner iron core under the magnetic attraction of the inner iron core, and the second end contacts the magnetic plate under the magnetic attraction of the magnetic plate. When the inner iron core floats relative to the magnetic plate, the elastic strip undergoes elastic deformation, and the magnetic conductor rotates about the rotation axis relative to the rigid support to maintain the first end in contact with the inner iron core and the second end in contact with the magnetic plate.

[0011] Furthermore, each of the core modules is coaxially arranged, and each of the core modules has a radial structure extending outward along the radial direction of the inner core. Multiple core modules are stacked sequentially along the axial direction of the inner core.

[0012] Furthermore, it also includes an outer iron core, a bottom iron core, and an insulating layer. The outer iron core is sleeved on the outside of the coil, and the bottom iron core is disposed at the same axial end of the inner iron core and the outer iron core. The inner iron core, the outer iron core, and the bottom iron core cooperate to form a magnetic circuit surrounding the coil. The magnetic guide plate is disposed between the inner iron core and the bottom iron core, and the insulating layer is disposed between the magnetic guide plate and the bottom iron core, and is connected to the magnetic guide plate and the bottom iron core respectively.

[0013] Furthermore, it also includes a forked connector, which has a first connector that is electrically connected to the connector end of the coil and a second connector that is electrically connected to an external circuit, wherein a plurality of parallel conductive branches are formed between the first connector and the second connector.

[0014] The beneficial effects of this invention are as follows: By stacking multiple iron core modules sequentially along the axial direction of the inner iron core and connecting them using a fixed structure, the iron core modules are less prone to relative displacement when subjected to vibration or alternating electromagnetic forces. This helps maintain the stability of the air gap size formed by the insulating spacers between adjacent iron core modules. Simultaneously, the inner iron core is connected to the magnetic plate via an elastic buffer assembly, allowing the inner iron core to float elastically in a controlled manner relative to the magnetic plate. This allows vibrations and impacts acting on the inner iron core to be buffered through the deformation of the elastic buffer assembly, reducing the direct transmission of vibrations to the stacked iron core modules. When the inner iron core floats, the magnetic conductor in the adaptive magnetic guide assembly moves relative to the support member according to the position change of the inner iron core, maintaining magnetic contact with both the inner iron core and the magnetic plate. This compensates for changes in the relative position between the inner iron core and the magnetic plate, preventing significant changes in the magnetic path due to elastic floating. Therefore, the fixed structure, elastic buffer components and adaptive magnetic conductive components work together to maintain the relative stability of the air gap inside the inner core while taking into account the vibration buffer and magnetic flux transmission of the inner core. This helps to reduce the fluctuations in magnetic circuit reluctance and inductance caused by vibration, and improves the stability of the reactor's operating state. Attached Figure Description

[0030] This invention provides an appendix Figures 1-10 In this embodiment of the invention, a reactor includes a coil 2, an inner iron core 3 disposed within the coil 2, and a magnetic conductive plate 6 disposed at a distance from one end of the inner iron core 3. An elastic buffer assembly 7 is provided between the inner iron core 3 and the magnetic guide plate 6. One side of the elastic buffer assembly 7 is connected to the inner iron core 3 and the other side is connected to the magnetic guide plate 6, so that the inner iron core 3 can float elastically relative to the magnetic guide plate 6. An adaptive magnetic guiding component 8 is also provided between the inner iron core 3 and the magnetic guiding plate 6. The adaptive magnetic guiding component 8 includes a support member 81 connected to the magnetic guiding plate 6 and a magnetic guiding body 82 movably connected to the support member 81. The magnetic guiding body 82 is magnetically engaged with the inner iron core 3 and the magnetic guiding plate 6 respectively, and can move relative to the support member 81 as the inner iron core 3 floats, so as to maintain the magnetic path between the inner iron core 3 and the magnetic guiding plate 6. The inner core 3 includes multiple core modules 31 stacked sequentially along the axial direction of the inner core 3, an insulating spacer 32 disposed between adjacent core modules 31, and a fixing structure 34 connecting the multiple core modules 31. An air gap 33 is formed between adjacent core modules 31 through the insulating spacer 32.

[0031] In this embodiment, coil 2 is arranged around inner iron core 3, which is located inside coil 2. When coil 2 is energized, it generates an alternating magnetic field. Inner iron core 3 guides the magnetic flux generated by coil 2 to enable the reactor to exhibit the desired electromagnetic characteristics. Magnetic guide plate 6 is disposed at one axial end of inner iron core 3, and is arranged opposite to and spaced apart from this axial end. Magnetic guide plate 6 receives the magnetic flux drawn from inner iron core 3 and, together with inner iron core 3, forms part of the magnetic flux transmission path of the reactor.

[0032] The inner core 3 is composed of multiple core modules 31, which are stacked sequentially along the axial direction of the inner core 3. An insulating spacer 32 is provided between adjacent core modules 31, creating an air gap 33 between them. The air gap 33 increases the magnetic reluctance of the magnetic circuit containing the inner core 3, thereby adjusting the inductive characteristics of the reactor and reducing the possibility of excessive magnetic saturation of the inner core 3 during operation.

[0033] Multiple core modules 31 are interconnected by a fixing structure 34. The fixing structure 34 acts on the multiple core modules 31, keeping them stacked along the axial direction of the inner core 3 and restricting relative movement between adjacent core modules 31. Thus, the multiple core modules 31 together form a relatively stable inner core 3. When the reactor is subjected to vibration, shock, or periodic electromagnetic force, each core module 31 is less likely to move independently, thereby reducing relative misalignment between adjacent core modules 31 and maintaining the dimensional stability of the air gap 33 formed by the insulating spacer 32.

[0034] An elastic buffer assembly 7 is provided between the inner iron core 3 and the magnetic conductive plate 6. One side of the elastic buffer assembly 7 is connected to the inner iron core 3, and the other side is connected to the magnetic conductive plate 6, so that the inner iron core 3 is supported on one side of the magnetic conductive plate 6 by the elastic buffer assembly 7. The elastic buffer assembly 7 forms an elastic connection between the inner iron core 3 and the magnetic conductive plate 6, which serves to support the inner iron core 3 and allows the inner iron core 3 to undergo limited elastic floating relative to the magnetic conductive plate 6 when subjected to vibration or electromagnetic forces.

[0035] When the inner core 3 shifts relative to the magnetic plate 6, the elastic buffer assembly 7 undergoes elastic deformation along with the inner core 3, absorbing and buffering some of the vibrational energy acting on the inner core 3. Since multiple core modules 31 are connected by the fixed structure 34, the floating of the inner core 3 is primarily manifested as the collective movement of multiple core modules 31 relative to the magnetic plate 6, rather than individual relative movement between the core modules 31. Therefore, the elastic buffer assembly 7 and the fixed structure 34 work together to allow the inner core 3 to release vibrations through overall floating while maintaining the relative stability of the air gaps 33 within the inner core 3.

[0036] An adaptive magnetic guiding component 8 is also provided between the inner iron core 3 and the magnetic guiding plate 6. The adaptive magnetic guiding component 8 includes a support member 81 and a magnetic guide body 82. The support member 81 is connected to the magnetic guiding plate 6 and provides a mounting and movable foundation for the magnetic guide body 82. The magnetic guide body 82 is movably connected to the support member 81 and is located between the inner iron core 3 and the magnetic guiding plate 6. The magnetic guide body 82 forms a magnetic guiding engagement with both the inner iron core 3 and the magnetic guiding plate 6, so that the magnetic flux in the inner iron core 3 can be transmitted to the magnetic guiding plate 6 through the magnetic guide body 82, or the magnetic flux in the magnetic guiding plate 6 can be transmitted to the inner iron core 3 through the magnetic guide body 82.

[0037] The magnetic conductor 82 and the support member 81 are movably connected, allowing the magnetic conductor 82 to move relative to the support member 81 in accordance with the floating of the inner iron core 3. When the position of the inner iron core 3 relative to the magnetic plate 6 changes, the spacing between the inner iron core 3 and the magnetic plate 6 changes accordingly. Under the influence of the positional change of the inner iron core 3, the magnetic conductor 82 moves relative to the support member 81 to adjust its positional relationship with the inner iron core 3 and the magnetic plate 6. Thus, without hindering the elastic floating of the inner iron core 3, the magnetic conductor 82 can continue to form magnetic engagement with both the inner iron core 3 and the magnetic plate 6, thereby maintaining the magnetic path between them.

[0038] Furthermore, in assembling the reactor, multiple core modules 31 are first stacked sequentially along the axial direction of the inner core 3, and insulating spacers 32 are placed between adjacent core modules 31 to form an air gap 33. Then, the multiple core modules 31 are connected by a fixing structure 34, so that the multiple core modules 31 together form the inner core 3. The connected inner core 3 is placed inside the coil 2, and a magnetic plate 6 is placed at one axial end of the inner core 3, so that the magnetic plate 6 is opposite to the inner core 3 and spaced apart. Subsequently, an elastic buffer assembly 7 is connected between the inner core 3 and the magnetic plate 6, so that the inner core 3 can float elastically relative to the magnetic plate 6 through the elastic buffer assembly 7. Then, the support 81 of the adaptive magnetic guide assembly 8 is connected to the magnetic plate 6, and the magnetic guide body 82 is movably connected to the support 81, so that the magnetic guide body 82 forms a magnetic engagement with the inner core 3 and the magnetic plate 6 respectively.

[0039] Specifically, when the reactor is working, a working current is first passed through coil 2, which generates a magnetic field. The inner iron core 3 guides the magnetic flux generated by coil 2. The magnetic flux is transmitted through the inner iron core 3, which is composed of multiple iron core modules 31. The air gap 33 between adjacent iron core modules 31 adjusts the magnetic reluctance of the magnetic circuit. The inner iron core 3 and the magnetic guide plate 6 are connected by a magnetic guide body 82, forming a magnetic flux transmission path, allowing the magnetic flux to be transmitted between the inner iron core 3, the magnetic guide body 82, and the magnetic guide plate 6.

[0040] When the reactor is subjected to external vibration or periodic electromagnetic force generated by the energization of coil 2, the fixing structure 34 keeps the multiple core modules 31 connected to each other, reducing the possibility of relative misalignment between the core modules 31. At the same time, the inner core 3 floats elastically relative to the magnetic plate 6 through the elastic buffer component 7, and the elastic buffer component 7 buffers the vibration of the inner core 3 through elastic deformation. During the floating process of the inner core 3, the magnetic conductor 82 moves relative to the support member 81 with the position change of the inner core 3, so that the magnetic conductor 82 adapts to the change in the relative position between the inner core 3 and the magnetic plate 6, and continues to form a magnetically conductive engagement with the inner core 3 and the magnetic plate 6.

[0041] When the vibration or force acting on the inner core 3 weakens, the elastic buffer component 7, under its elastic recovery action, causes the inner core 3 to tend to return to its original position. The magnetic conductor 82 moves accordingly relative to the support member 81 as the inner core 3 returns to its original position. During this process, the adaptive magnetic conductor component 8 continuously compensates for the relative positional changes between the inner core 3 and the magnetic conductor plate 6, thereby reducing the impact of the elastic floating of the inner core 3 on the stability of magnetic flux transmission.

[0042] Through the above structure, the fixed structure 34 enables multiple core modules 31 to jointly form a relatively stable inner core 3, reducing the relative movement between core modules 31 and making the air gap 33 between adjacent core modules 31 less prone to change due to vibration; the elastic buffer component 7 enables the inner core 3 to float elastically relative to the magnetic guide plate 6 in an integral form, reducing the degree to which vibration is directly transmitted to the stacking interface of the core modules 31; the adaptive magnetic guide component 8 can adjust the position of the magnetic guide body 82 according to the floating of the inner core 3, maintaining the magnetic path between the inner core 3 and the magnetic guide plate 6. Thus, this embodiment can take into account both the vibration reduction requirements of the inner core 3 and the magnetic circuit stability requirements, which is beneficial to improving the stability of the reactor's air gap 33, inductance, and operating state.

[0043] The fixing structure 34 includes a threaded tie rod 341 made of non-magnetic insulating material and a nut 342 that mates with the threaded tie rod 341. The threaded tie rod 341 is sequentially inserted into a plurality of core modules 31 along the axial direction of the inner core 3. The nut 342 is threaded to the threaded tie rod 341 and abuts against the core module 31 located at the axial end of the inner core 3, so as to press the plurality of core modules 31 together along the stacking direction of the core modules 31.

[0044] In this embodiment, the inner core 3 is formed by stacking multiple core modules 31 sequentially along its axial direction. Adjacent core modules 31 are spaced apart by insulating spacers 32 to form an air gap 33 for adjusting the magnetic reluctance of the magnetic circuit. The fixing structure 34 includes a threaded tie rod 341 and a nut 342 that is threadedly engaged with the threaded tie rod 341. The threaded tie rod 341 is made of a non-magnetic insulating material so that while bearing the axial connection and clamping function, it reduces its impact on the magnetic flux distribution and electrical insulation performance of the inner core 3.

[0045] Each core module 31 has a pass-through position for a threaded tie rod 341. After multiple core modules 31 are arranged in a predetermined stacking order, the pass-through positions on each core module 31 correspond to each other along the axial direction of the inner core 3. The threaded tie rod 341 passes sequentially through multiple core modules 31 along the axial direction of the inner core 3, enabling multiple core modules 31 to establish an axial connection through the same threaded tie rod 341. A nut 342 is threaded onto the threaded tie rod 341 and abuts against the core module 31 located at the axial end of the inner core 3. By tightening the nut 342, the nut 342 moves axially along the threaded tie rod 341 and applies an axial clamping force to the end core module 31. This axial clamping force is sequentially transmitted to the remaining core modules 31 along the stacking direction of the core modules 31, maintaining a mutually clamped connection between the multiple core modules 31.

[0046] During the assembly of the fixed structure 34, the insulating spacers 32 are first placed between adjacent core modules 31. Then, multiple core modules 31 are stacked sequentially along the axial direction of the inner core 3, ensuring that the insertion positions on each core module 31 correspond to each other. Subsequently, threaded rods 341 are passed through multiple core modules 31 sequentially, and nuts 342 are screwed onto the threaded rods 341. By gradually tightening the nuts 342, the multiple core modules 31 are brought closer together along the stacking direction, while the insulating spacers 32 are stably held between adjacent core modules 31. After the nuts 342 reach the predetermined compression state, the multiple core modules 31 form a relatively stable connected whole through the threaded rods 341 and the nuts 342.

[0047] The clamping force applied by the nut 342 is preferably sufficient to limit the relative movement between the core modules 31 without causing excessive compression of the insulating spacer 32. As a result, the insulating spacer 32 can maintain the spacing between adjacent core modules 31, so that the air gap 33 has a relatively stable size; the fixing structure 34 reduces the possibility of relative misalignment of the core modules 31 in the radial or axial direction by axial constraint.

[0048] When the reactor is working, the coil 2 is energized to generate an alternating magnetic field, and each core module 31 in the inner core 3 is subjected to a corresponding electromagnetic force. Since multiple core modules 31 are axially connected by threaded rods 341 and nuts 342, a single core module 31 is not easily vibrated independently relative to other core modules 31. When the inner core 3 is subjected to periodic electromagnetic force or external vibration, the threaded rods 341 form an axial connection between the multiple core modules 31, and the nuts 342 maintain the compression state between the multiple core modules 31, thereby reducing the possibility of loosening and relative displacement between adjacent core modules 31.

[0049] When the inner core 3 floats elastically relative to the magnetic plate 6 via the elastic buffer assembly 7, multiple core modules 31 move together with the inner core 3 under the connection of the fixed structure 34, and it is not easy for independent movements to form between the core modules 31. Thus, the fixed structure 34 and the elastic buffer assembly 7 cooperate: the elastic buffer assembly 7 is used to buffer the vibration of the inner core 3 as a whole, while the fixed structure 34 is used to maintain the relative positions between the core modules 31 inside the inner core 3, so that the inner core 3 can still maintain the stability of the air gap 33 during the overall floating process.

[0050] For example, the threaded tie rod 341 can be a rod-shaped structure with threads along its entire length, or it can be threaded only at the end used to install the nut 342, as long as multiple core modules 31 can be sequentially inserted and axially locked with the nut 342. The length of the threaded tie rod 341 can be determined according to the number of core modules 31, the axial dimension of each core module 31, and the thickness of the insulating spacer 32. The diameter of the threaded tie rod 341 can be determined according to the mass of the inner core 3 and the required axial clamping force.

[0051] The threaded tie rod 341 can be a single rod or multiple rods depending on the size and stress of the core module 31. When multiple threaded tie rods 341 are used, they can be spaced apart around the axis of the inner core 3 to ensure that the axial clamping force on the multiple core modules 31 is relatively uniform, reducing the possibility of tilting of the core module 31 or uneven air gap 33 due to excessive local clamping force. The specific insertion position of the threaded tie rod 341 can be selected according to the structure of the core module 31, as long as it can achieve a stable connection between multiple core modules 31 and avoid significantly affecting the normal magnetic conductivity of the inner core 3.

[0052] The non-magnetic insulating material used for the threaded tie rod 341 can be a composite material with corresponding mechanical strength and insulation properties. For example, it can be glass fiber reinforced resin material, fiber reinforced insulating material, or other non-magnetic insulating material capable of withstanding axial tensile force. The specific type of material can be selected according to the rated operating conditions of the reactor, the mass of the inner core 3, the operating temperature, and the insulation requirements.

[0053] Nut 342 can be located at one end of threaded tie rod 341, or at both ends of threaded tie rod 341. When one end of threaded tie rod 341 has an end structure that can restrict the axial movement of core module 31, nut 342 can be located at the other end of threaded tie rod 341; when both ends of threaded tie rod 341 are threaded, nuts 342 can be installed at both ends, and multiple core modules 31 can be pressed together by the nuts 342 at both ends. Nut 342 can also be a common nut 342, a self-locking nut 342, or a double nut 342 structure that cooperates with each other, to reduce the possibility of nut 342 loosening during long-term vibration of reactor. The above forms are all implementation methods that apply axial clamping force to multiple core modules 31 by cooperating with threaded tie rod 341 and nut 342.

[0054] The elastic buffer assembly 7 includes an elastic support ring 71 made of a non-magnetic insulating elastic material. The elastic support ring 71 is arranged around the axis of the inner iron core 3. The elastic support ring 71 is connected to the inner iron core 3 on one side along the axial direction of the inner iron core 3, and connected to the magnetic plate 6 on the other side.

[0055] In this embodiment, the elastic buffer assembly 7 includes an elastic support ring 71. The elastic support ring 71 is made of a non-magnetic insulating elastic material and is arranged around the axis of the inner iron core 3. The elastic support ring 71 is connected to the inner iron core 3 on one side along the axial direction of the inner iron core 3, and connected to the magnetic plate 6 on the other side along the axial direction of the inner iron core 3, so that the inner iron core 3 is supported on one side of the magnetic plate 6 by the elastic support ring 71, and is arranged in a relative and spaced manner with respect to the magnetic plate 6.

[0056] The elastic support ring 71 forms an elastic support between the inner iron core 3 and the magnetic plate 6. The weight of the inner iron core 3 and the forces acting on it during operation are transmitted to the elastic support ring 71, which then transmits the load to the magnetic plate 6. Because the elastic support ring 71 has elastic deformation capability, when the inner iron core 3 is subjected to axial vibration, impact, or periodic forces, the elastic support ring 71 can allow the inner iron core 3 to float relative to the magnetic plate 6 with a limited amplitude through compression, rebound, or elastic deformation adapted to the direction of the force.

[0057] The elastic support ring 71 is arranged around the axis of the inner iron core 3, so that it can form a continuous or substantially continuous elastic support area along the circumference of the inner iron core 3. Compared with the method of setting support components only locally below the inner iron core 3, the circumferential support can make the supporting force on the inner iron core 3 relatively uniform along the circumference, reducing the possibility of the inner iron core 3 tilting, shifting, or being subjected to excessive local force due to local support force concentration.

[0058] One side of the elastic support ring 71 is connected to the inner iron core 3, allowing the inner iron core 3 to transmit force to the elastic support ring 71 when it floats; the other side of the elastic support ring 71 is connected to the magnetic guide plate 6, providing a relatively stable support base for the elastic support ring 71 when it undergoes elastic deformation. The connection referred to here can be understood as a connection that maintains a relative positional relationship between the elastic support ring 71 and the inner iron core 3 and the magnetic guide plate 6, and enables the transmission of load during the floating of the inner iron core 3.

[0059] During assembly, the elastic support ring 71 is first placed on the side of the magnetic guide plate 6 facing the inner iron core 3, and the elastic support ring 71 is arranged around the predetermined axis of the inner iron core 3; then, the inner iron core 3 is placed on the side of the elastic support ring 71 facing away from the magnetic guide plate 6, so that the elastic support ring 71 is located between the axial end of the inner iron core 3 and the magnetic guide plate 6; subsequently, the elastic support ring 71 is connected to the inner iron core 3 and the magnetic guide plate 6 on both sides along the axial direction, so that the elastic support ring 71 can provide elastic support for the inner iron core 3.

[0060] After assembly, the elastic support ring 71 can be in a natural state between the inner iron core 3 and the magnetic plate 6, or it can undergo a certain degree of initial elastic deformation under the load of the inner iron core 3. The initial elastic deformation can maintain a stable force relationship between the elastic support ring 71, the inner iron core 3, and the magnetic plate 6, reducing the possibility of the elastic support ring 71 detaching from or intermittently colliding with adjacent components during reactor operation.

[0061] When the reactor starts working, coil 2 is energized and generates a magnetic field, with the inner iron core 3 participating in the magnetic flux transmission. Multiple iron core modules 31 within the inner iron core 3 are connected by a fixing structure 34, allowing the inner iron core 3 to be supported as a whole on the elastic support ring 71. When the inner iron core 3 is in a relatively stable state, the elastic support ring 71 supports the inner iron core 3 and maintains the distance between the inner iron core 3 and the magnetic plate 6.

[0062] When the reactor is subjected to external vibration or the inner core 3 is subjected to periodic force, the inner core 3 transmits the corresponding force to the elastic support ring 71. Under this force, the elastic support ring 71 undergoes elastic deformation, allowing the inner core 3 to float elastically relative to the magnetic plate 6. Through the deformation of the elastic support ring 71, some of the vibration energy acting on the inner core 3 is absorbed or buffered, thereby reducing the degree to which vibration is directly transmitted to the connection positions of the various core modules 31 inside the inner core 3.

[0063] During the floating process of the inner iron core 3, the adaptive magnetic guiding component 8 adapts to the changes in the relative position between the inner iron core 3 and the magnetic guiding plate 6 to maintain the magnetic path between the inner iron core 3 and the magnetic guiding plate 6. The elastic support ring 71 mainly undertakes the functions of elastic support and vibration buffering, while the adaptive magnetic guiding component 8 mainly adapts to the positional changes caused by the floating of the inner iron core 3. The two work together to ensure that the inner iron core 3 can maintain the required magnetic flux transmission state while achieving vibration reduction.

[0064] When external vibrations or periodic forces weaken, the elastic support ring 71 gradually recovers using its own elastic restoring force, and drives the inner iron core 3 to move back to its original support position. Thus, the inner iron core 3 can float in a controlled manner under the constraint of the elastic support ring 71, without creating unrestricted displacement between the inner iron core 3 and the magnetic plate 6.

[0065] For example, the elastic support ring 71 can be a continuously closed ring structure, or it can be a ring structure with connecting parts while maintaining its arrangement around the axis of the inner iron core 3 to form a circumferential elastic support. The inner contour of the elastic support ring 71 can be adapted to the outer contour of the axial end of the inner iron core 3, while the outer contour can be set according to the installation space and load-bearing requirements of the magnetic guide plate 6.

[0066] The cross-section of the elastic support ring 71 can be circular, elliptical, rectangular, trapezoidal, or other shapes that can form a stable elastic support between the inner iron core 3 and the magnetic plate 6. When a circular or elliptical cross-section is used, the elastic support ring 71 can form a relatively gentle elastic deformation during compression; when a rectangular or trapezoidal cross-section is used, the support area and deformation capacity of the elastic support ring 71 can be changed by adjusting the width and height of the cross-section.

[0067] The axial dimension of the elastic support ring 71 can be determined according to the preset interval between the inner iron core 3 and the magnetic plate 6, and its radial dimension can be determined according to the weight of the inner iron core 3, the circumferential support range, and the required support stability. The size of the elastic support ring 71 should be such that it can stably support the inner iron core 3 and provide the required floating space for the inner iron core 3.

[0068] The non-magnetic insulating elastic material used in the elastic support ring 71 can be a material with insulating properties, elastic recovery properties, and corresponding mechanical strength. For example, it can be an elastic polymer material, an elastic composite insulating material, or other insulating elastic materials that do not have a significant magnetic influence in the reactor's operating environment. The material's hardness, elastic modulus, temperature resistance, and aging resistance can be selected based on the mass of the inner core 3, the expected vibration intensity, and the reactor's operating conditions.

[0069] The elastic support ring 71 can be connected to the inner iron core 3 and the magnetic guide plate 6 by means of bonding, embedding, snapping, pressing, or mutual abutment and limiting. When bonding, the elastic support ring 71 can maintain a stable position with the inner iron core 3 and the magnetic guide plate 6. When embedding or snapping, mounting positions that accommodate or restrict the movement of the elastic support ring 71 can be formed on the corresponding components. When pressing or abutting, the axial load applied by the inner iron core 3 can be used to hold the elastic support ring 71 between the inner iron core 3 and the magnetic guide plate 6. All of the above connection methods aim to enable the elastic support ring 71 to transmit loads and maintain effective support during the floating of the inner iron core 3.

[0070] While achieving the same elastic support and buffering purpose, the elastic support ring 71 can also be provided with a structure for adjusting the deformation capacity, such as changing the local thickness or forming a contour that adapts to the direction of force. However, the above structures do not change the basic relationship between the elastic support ring 71, which is arranged around the axis of the inner iron core 3 and connects the inner iron core 3 and the magnetic plate 6 respectively.

[0071] The adaptive magnetic conductive component 8 is configured in multiple groups, and the multiple groups of the adaptive magnetic conductive component 8 are arranged at intervals along the circumference of the inner iron core 3.

[0072] In this embodiment, multiple sets of adaptive magnetic conductive components 8 are arranged at intervals along the circumference of the inner iron core 3. Each set of adaptive magnetic conductive components 8 is located between the inner iron core 3 and the magnetic conductive plate 6, and includes a support member 81 connected to the magnetic conductive plate 6 and a magnetic conductive body 82 movably connected to the support member 81. Each support member 81 provides a mounting base for the corresponding magnetic conductive body 82, enabling each magnetic conductive body 82 to independently adapt between the inner iron core 3 and the magnetic conductive plate 6.

[0073] Multiple sets of adaptive magnetic conductive components 8 are arranged around the axis of the inner iron core 3, with each set of adaptive magnetic conductive components 8 spaced apart in the circumferential direction, so that multiple mutually separated magnetic conductive connection positions are formed between the inner iron core 3 and the magnetic conductive plate 6. The magnetic conductors 82 in each set of adaptive magnetic conductive components 8 are magnetically engaged with the inner iron core 3 and the magnetic conductive plate 6 respectively, so that the magnetic flux in the inner iron core 3 can be transmitted to the magnetic conductive plate 6 through multiple circumferentially distributed magnetic conductors 82, or the magnetic flux in the magnetic conductive plate 6 can be transmitted to the inner iron core 3 through multiple magnetic conductors 82.

[0074] The spacing between the adaptive magnetic conductive components 8 reduces local magnetic flux concentration caused by multiple magnetic conductors 82 being concentrated in the same area, and allows the magnetic flux between the inner iron core 3 and the magnetic conductive plate 6 to be transmitted through different circumferential positions. Thus, multiple sets of adaptive magnetic conductive components 8 together form a distributed magnetic conductive structure, so that the magnetic conductive cooperation between the inner iron core 3 and the magnetic conductive plate 6 no longer depends on a single magnetic conductive position.

[0075] Specifically, when the reactor is working, coil 2 is energized to generate a magnetic field, and the magnetic flux is transmitted in the inner iron core 3. Multiple sets of adaptive magnetic guiding components 8, located between the inner iron core 3 and the magnetic guiding plate 6, participate in the transmission of magnetic flux, enabling the magnetic flux to be transmitted between the inner iron core 3 and the magnetic guiding plate 6 through multiple circumferentially spaced magnetic guiding bodies 82. The multiple magnetic guiding positions share the magnetic flux between the inner iron core 3 and the magnetic guiding plate 6, which helps to make the magnetic flux distribution more balanced.

[0076] When the inner core 3 floats relative to the magnetic plate 6 under the action of the elastic buffer assembly 7, the relative distance between the inner core 3 and the magnetic plate 6 at different circumferential positions may change to the same or different degrees. The magnetic conductors 82 in each group of adaptive magnetic conductive assemblies 8 can move relative to the corresponding support 81 according to the change of their position, so as to adapt to the positional changes between different circumferential regions of the inner core 3 and the magnetic plate 6.

[0077] For example, when the inner core 3 floats substantially along its axial direction, multiple sets of magnetic conductors 82 can move accordingly with the axial displacement of the inner core 3 to maintain the magnetic path between the inner core 3 and the magnetic plate 6. When the inner core 3 tilts to a certain extent during its floating process, the magnetic conductors 82 at different circumferential positions can be adjusted according to the spacing changes in the corresponding areas, ensuring effective magnetic conduction at at least multiple circumferential positions. Thus, multiple sets of adaptive magnetic conductor components 8 can improve the adaptability of the magnetic structure to different floating states of the inner core 3.

[0078] When the vibration or external force acting on the inner iron core 3 is weakened, the inner iron core 3 tends to return to its original position under the action of the elastic buffer component 7. Each group of magnetic conductors 82 also moves accordingly relative to the corresponding support member 81 as the position of the inner iron core 3 returns to normal, so that multiple groups of magnetic conductors 82 continue to form a distributed magnetic flux transmission path between the inner iron core 3 and the magnetic plate 6.

[0079] For example, the number of adaptive magnetic conductive components 8 can be determined based on the radial dimension of the inner iron core 3, the installation space of the magnetic conductive plate 6, and the required magnetic flux transmission capacity. Multiple magnetic connection positions can be formed by setting two or more sets and arranging them at circumferential intervals along the inner iron core 3. For example, the adaptive magnetic conductive components 8 can be set to two, three, four, or more sets. When the number of components increases, the magnetic conductive positions between the inner iron core 3 and the magnetic conductive plate 6 can be increased accordingly, but sufficient space for movement should be reserved for each magnetic conductor 82.

[0080] Multiple sets of adaptive magnetic conductive components 8 can be evenly spaced along the circumference of the inner iron core 3, so that the circumferential angles of each set of adaptive magnetic conductive components 8 are basically the same, thereby providing relatively balanced magnetic support for the inner iron core 3. Alternatively, they can be non-uniformly spaced according to the magnetic flux distribution, stress state, or installation space of different areas of the inner iron core 3. Regardless of whether a uniform or non-uniform arrangement is adopted, the purpose is to ensure that the multiple sets of adaptive magnetic conductive components 8 can maintain the magnetic path between the inner iron core 3 and the magnetic conductive plate 6 at different circumferential positions.

[0081] Each group of adaptive magnetic guiding components 8 can be positioned circumferentially at the same distance from the axis of the inner iron core 3, so that multiple magnetic conductors 82 form a ring distribution around the inner iron core 3; alternatively, the installation distance between different adaptive magnetic guiding components 8 and the axis of the inner iron core 3 can be determined according to the end profile of the inner iron core 3 and the shape of the magnetic guiding plate 6. The support members 81 of each group of adaptive magnetic guiding components 8 can be independently connected to the magnetic guiding plate 6, or they can be connected to the magnetic guiding plate 6 through a common mounting base without affecting the independent movement of each magnetic conductor 82.

[0082] Each group of adaptive magnetic guiding components 8 can adopt the same structural dimensions, so that each magnetic conductor 82 has similar magnetic guiding capacity and range of motion; alternatively, the magnetic conductors 82 in different groups can have corresponding dimensions according to the spatial conditions or magnetic flux requirements of each installation location. The above-mentioned changes in quantity, spacing, and installation location do not change the basic structural relationship of multiple groups of adaptive magnetic guiding components 8 being spaced apart along the inner iron core 3 and maintaining magnetic guiding cooperation.

[0083] The support member 81 includes a frame 811 and an elastic connector 812. The frame 811 is fixedly connected to the magnetic plate 6, the elastic connector 812 is connected to the frame 811, and the magnetic conductor 82 is rotatably connected to the elastic connector 812 so that the magnetic conductor 82 can swing relative to the frame 811.

[0084] In this embodiment, the adaptive magnetic conductive assembly 8 is disposed between the inner iron core 3 and the magnetic conductive plate 6, and includes a support member 81 and a magnetic conductor 82. The support member 81 is used to mount the magnetic conductor 82 on the magnetic conductive plate 6 and to provide the magnetic conductor 82 with a position adjustment base that can adapt to the floating of the inner iron core 3; the magnetic conductor 82 is used to transmit magnetic flux between the inner iron core 3 and the magnetic conductive plate 6 to maintain the magnetic path between the inner iron core 3 and the magnetic conductive plate 6.

[0085] The support member 81 includes a frame 811 and an elastic connector 812. The frame 811 is fixedly connected to the side of the magnetic plate 6 facing the inner iron core 3 to keep the frame 811 stable relative to the magnetic plate 6. The elastic connector 812 is connected to the frame 811, and the magnetic conductor 82 is rotatably connected to the elastic connector 812. Thus, the magnetic conductor 82 is not directly and rigidly fixed to the magnetic plate 6, but rather its installation relationship with the magnetic plate 6 is established sequentially through the elastic connector 812 and the frame 811.

[0086] The frame 811 serves as the fixed base for the support member 81, bearing the force transmitted by the magnetic conductor 82 and the elastic connector 812, and transferring this force to the magnetic plate 6. The fixed connection between the frame 811 and the magnetic plate 6 restricts the frame 811 from making unintended movements relative to the magnetic plate 6, thereby providing a stable reference base for the swing of the magnetic conductor 82.

[0087] The elastic connector 812 is disposed between the frame 811 and the magnetic conductor 82. On the one hand, the elastic connector 812 is used to support the magnetic conductor 82 and hold the magnetic conductor 82 between the inner iron core 3 and the magnetic plate 6; on the other hand, the elastic connector 812 can adapt to the positional changes of the magnetic conductor 82 during the swinging process through its own elastic deformation, so as to avoid the formation of a completely rigid motion constraint between the magnetic conductor 82 and the frame 811.

[0088] The magnetic conductor 82 is rotatably connected to the elastic connector 812, allowing the magnetic conductor 82 to swing relative to the frame 811. This swinging refers to the magnetic conductor 82 changing its position or orientation between the inner iron core 3 and the magnetic guide plate 6, based on its rotatable connection with the elastic connector 812. When the magnetic conductor 82 swings, its magnetic engagement with the inner iron core 3 and the magnetic guide plate 6 is adjusted accordingly to accommodate the floating of the inner iron core 3 relative to the magnetic guide plate 6.

[0089] When the reactor is in operation, coil 2 generates a magnetic field, and the magnetic flux is transmitted through the inner iron core 3. The magnetic conductor 82 forms a magnetically conductive fit with the inner iron core 3 and the magnetic plate 6 respectively, so that the magnetic flux in the inner iron core 3 can be transmitted to the magnetic plate 6 through the magnetic conductor 82, or the magnetic flux in the magnetic plate 6 can be transmitted to the inner iron core 3 through the magnetic conductor 82.

[0090] When the inner iron core 3 remains stable relative to the magnetic plate 6, the elastic connector 812 supports the magnetic conductor 82 in a position that is compatible with the inner iron core 3 and the magnetic plate 6. The magnetic conductor 82 maintains its corresponding posture through the rotational connection between itself and the elastic connector 812, thereby maintaining the magnetic flux transmission between the inner iron core 3 and the magnetic plate 6.

[0091] When the reactor is subjected to vibration or the inner core 3 is subjected to periodic force, the inner core 3 elastically floats relative to the magnetic plate 6 under the action of the elastic buffer component 7. Since the frame 811 is fixed on the magnetic plate 6, the position of the frame 811 remains stable with the magnetic plate 6, while the magnetic conductor 82 rotates relative to the elastic connector 812 due to the change in the relative position of the inner core 3.

[0092] During the rotation of the magnetic conductor 82, the elastic connector 812 can generate corresponding elastic deformation according to the position change of the magnetic conductor 82, so as to release the additional load generated during the swing of the magnetic conductor 82 and reduce the restriction of the rigid support on the movement of the magnetic conductor 82. The magnetic conductor 82 adjusts its position or attitude relative to the inner iron core 3 and the magnetic plate 6 by rotating, thereby adapting to the change in the relative position between the inner iron core 3 and the magnetic plate 6.

[0093] When the floating direction or amplitude of the inner iron core 3 changes, the magnetic conductor 82 can correspondingly change its swing direction or swing amplitude, and the elastic connector 812 will deform accordingly with the movement of the magnetic conductor 82. Thus, the magnetic conductor 82 can follow the position change of the inner iron core 3 within a certain range of motion, without requiring the frame 811 or the magnetic plate 6 to move synchronously.

[0094] When the vibration or force acting on the inner iron core 3 weakens, the inner iron core 3 tends to return to its original position under the action of the elastic buffer component 7. As the position of the inner iron core 3 returns to normal, the magnetic conductor 82 rotates in the opposite direction relative to the elastic connector 812, and the elastic connector 812 also gradually returns to a deformation degree that is compatible with the current state of the inner iron core 3, so that the magnetic conductor 82 tends to return to its original magnetic engagement position.

[0095] Therefore, in this embodiment, the adaptive magnetic guiding component 8 forms a two-level positional adaptation relationship through the frame 811, the elastic connector 812, and the magnetic guide 82: the elastic connector 812 can provide flexible displacement compensation through elastic deformation, and the magnetic guide 82 can change its own posture by rotation. The two modes of movement cooperate with each other, enabling the adaptive magnetic guiding component 8 to adapt to the floating of the inner iron core 3 relative to the magnetic guide plate 6.

[0096] For example, the frame 811 can be a support structure that can be fixed to the magnetic plate 6 and provides an installation position for the elastic connector 812. The frame 811 can be frame-shaped, plate-shaped, seat-shaped, or other shape with support capabilities, and its specific shape can be determined according to the installation space on the magnetic plate 6, the size of the magnetic body 82, and the required swing range of the magnetic body 82.

[0097] The frame 811 and the magnetic guide plate 6 can be connected by a fastening connection, interlocking, snap-fitting, adhesive bonding, or other fixed connection methods that can restrict the movement of the frame 811 relative to the magnetic guide plate 6. The frame 811 can also be connected to the magnetic guide plate 6 via a mounting part provided on the magnetic guide plate 6. All of the above installation methods aim to ensure that the frame 811 provides stable support for the elastic connector 812 and the magnetic guide 82.

[0098] The elastic connector 812 can be a connection structure with elastic deformation capability, and its shape can be set according to the relative position between the frame 811 and the magnetic conductor 82. For example, the elastic connector 812 can be in the form of a sheet, strip, ring, bend, or other structure that can generate elastic deformation while bearing the magnetic conductor 82. The size and elastic performance of the elastic connector 812 can be selected according to the mass of the magnetic conductor 82, the floating range of the inner iron core 3, and the required swing resistance of the magnetic conductor 82.

[0099] The elastic connector 812 can be installed on the frame 811 by fixing, embedding, clamping or other connection methods. The connection position between the elastic connector 812 and the frame 811 can be set on one side, both sides of the frame 811 or in a position that is compatible with the movement direction of the magnetic conductor 82, as long as the elastic connector 812 can stably support the magnetic conductor 82 and allow the magnetic conductor 82 to swing relative to the frame 811.

[0100] The magnetic conductor 82 can be block-shaped, sheet-shaped, rod-shaped, arc-shaped, or other structures capable of transmitting magnetic flux between the inner iron core 3 and the magnetic conductor plate 6. The shape of the magnetic conductor 82 can be adapted to the spatial relationship between the corresponding areas of the inner iron core 3 and the magnetic conductor plate 6, so that the magnetic conductor 82 can maintain the required magnetic conduction during the swinging process and avoid interference with the frame 811 that would hinder its movement.

[0101] The magnetic conductor 82 and the elastic connector 812 can be connected in a movable manner that allows for relative rotation. This rotational connection allows the magnetic conductor 82 to oscillate in one direction or in both directions within a range that corresponds to the floating direction of the inner iron core 3. The oscillation range of the magnetic conductor 82 can be determined based on the expected floating range of the inner iron core 3 relative to the magnetic plate 6, ensuring that the magnetic conductor 82 has sufficient positional adaptability without excessive oscillation that deviates from the predetermined working area.

[0102] To achieve the same technical objective, the frame 811 and the elastic connector 812 can also form a combined support structure, as long as the frame 811 can maintain a fixed connection with the magnetic plate 6, the elastic connector 812 can connect the frame 811 and provide elastic support for the magnetic body 82, and the magnetic body 82 can rotate relative to the elastic connector 812. The changes in shape, material, installation method, and connection method described above do not alter the basic connection relationship between the frame 811, the elastic connector 812, and the magnetic body 82 in this embodiment.

[0103] Compared to a structure that rigidly fixes the magnetic conductor 82 to the magnetic plate 6, this embodiment uses a frame 811 to stably mount the adaptive magnetic conductor assembly 8 to the magnetic plate 6, and uses an elastic connector 812 to flexibly support the magnetic conductor 82, allowing the magnetic conductor 82 to swing relative to the frame 811. When the inner iron core 3 floats relative to the magnetic plate 6, the magnetic conductor 82 can adjust its position or posture by rotating, and the elastic connector 812 can adapt to the movement of the magnetic conductor 82 through elastic deformation, thereby reducing the impact of the inner iron core 3's floating on the magnetic engagement state.

[0104] The elastic connector 812 includes a rigid support 814 and an elastic strip 8121 connecting the frame 811 and the rigid support 814. One end of the elastic strip 8121 is connected to the frame 811 and the other end is connected to the rigid support 814. The magnetic conductor 82 is provided with a rotating shaft 813, which is inserted into the rigid support 814 and rotatably connected to the rigid support 814.

[0105] Based on Embodiment 5, this embodiment further describes the elastic connector 812 and the rotational connection structure between the magnetic conductor 82 and the elastic connector 812. Apart from the elastic connector 812 and the rotational connection structure described in this embodiment, the remaining components, connections, and operating modes of the reactor can be referred to Embodiments 1 and 5.

[0106] In this embodiment, the adaptive magnetic guiding component 8 includes a support member 81 and a magnetic guiding body 82. The support member 81 includes a frame 811 fixedly connected to the magnetic guiding plate 6 and an elastic connector 812 connected to the frame 811. The elastic connector 812 includes a rigid support 814 and an elastic strip 8121 connecting the frame 811 and the rigid support 814. One end of the elastic strip 8121 is connected to the frame 811, and the other end is connected to the rigid support 814, so that the rigid support 814 is elastically supported on the frame 811 by the elastic strip 8121. A rotating shaft 813 is provided on the magnetic guiding body 82. The rotating shaft 813 is inserted into the rigid support 814 and rotatably connected to the rigid support 814, thereby enabling the magnetic guiding body 82 to swing relative to the frame 811 with the rigid support 814 as the rotating support base.

[0107] The frame 811 is used to mount the elastic connector 812 and the magnetic conductor 82 on the magnetic plate 6, and to provide a relatively stable fixed base for the elastic strip 8121. The rigid support 814 is used to support the rotating shaft 813 of the magnetic conductor 82 and to maintain the structural stability of the rotating connection part during the swing of the magnetic conductor 82. The elastic strip 8121 is disposed between the frame 811 and the rigid support 814, and is used to suspend or elastically support the rigid support 814 on the frame 811, so that the rigid support 814 can produce a certain degree of elastic displacement relative to the frame 811 with the force applied to the magnetic conductor 82.

[0108] The rotating shaft 813 on the magnetic conductor 82 forms the axis of rotation of the magnetic conductor 82 relative to the rigid support 814. After the rotating shaft 813 is inserted into the rigid support 814, the rigid support 814 supports and limits the rotating shaft 813, allowing the magnetic conductor 82 to rotate around the axis of the rotating shaft 813, while preventing the magnetic conductor 82 from leaving the predetermined installation position. Therefore, the movement of the magnetic conductor 82 is not achieved solely by the overall deformation of the elastic strip 8121, but by the combined rotation between the rotating shaft 813 and the rigid support 814, as well as the elastic deformation of the elastic strip 8121.

[0109] Structurally, the magnetic plate 6, frame 811, elastic strip 8121, rigid support 814, rotating shaft 813, and magnetic conductor 82 are sequentially connected. The frame 811 is fixed relative to the magnetic plate 6, the rigid support 814 is elastically connected to the frame 811 via the elastic strip 8121, and the magnetic conductor 82 is rotatably connected to the rigid support 814 via the rotating shaft 813. This connection allows the magnetic conductor 82 to rotate freely relative to the rigid support 814, while simultaneously allowing the rigid support 814 to move elastically relative to the frame 811.

[0110] For example, the elastic strip 8121 can be one or more. When multiple elastic strips 8121 are provided, each elastic strip 8121 can be connected at different positions of the rigid support 814 to jointly support the rigid support 814 and the magnetic conductor 82, and to keep the rigid support 814 relatively stable under force. Multiple elastic strips 8121 can be arranged at intervals, and their specific number and position can be determined according to the size of the rigid support 814, the mass of the magnetic conductor 82, and the required elastic deformation range.

[0111] The elastic strip 8121 can be straight, curved, sheet-like, or other shapes capable of connecting the frame 811 and the rigid support 814 and producing elastic deformation. The length, width, and thickness of the elastic strip 8121 can be set according to the required displacement range and elastic support capacity of the rigid support 814. The dimensions of the elastic strip 8121 are preferably designed to stably support the rigid support 814 and the magnetic conductor 82, while allowing the rigid support 814 to make adaptive displacements.

[0112] The elastic strip 8121 can be made of elastic polymer materials, elastic insulating composite materials, or other materials with elastic recovery capabilities. The material of the elastic strip 8121 can be selected according to the operating temperature of the reactor, the mass of the magnetic conductor 82, the expected fluctuation range, and the service life requirements. The above material examples are only used to illustrate the possible embodiments of the elastic strip 8121 and do not constitute a limitation on the material of the elastic strip 8121.

[0113] The elastic strip 8121 can be connected to the frame 811 and the rigid support 814 by adhesive bonding, embedding, snap-fitting, clamping, or other load-bearing connection methods. For example, the ends of the elastic strip 8121 can be accommodated in the mounting positions provided on the frame 811 and the rigid support 814, or they can be fixed to the corresponding surfaces of the frame 811 and the rigid support 814. The specific connection method should be such that the elastic strip 8121 does not easily detach from the frame 811 and the rigid support 814 during repeated deformation.

[0114] The rigid support 814 can be in the form of a block, seat, sleeve, or other structure capable of accommodating and supporting the rotating shaft 813. Hole-shaped, slot-shaped, or partially enclosed mounting positions for inserting the rotating shaft 813 can be formed on the rigid support 814, as long as they can provide rotational support for the rotating shaft 813 and prevent the magnetic conductor 82 from leaving the predetermined position.

[0115] The rigid support 814 can be made of a material with appropriate structural strength and wear resistance. For example, a non-magnetic insulating material can be used to reduce the impact of the rigid support 814 on the magnetic circuit and insulation performance of the reactor; structural materials that have been treated to have the required performance can also be used, provided that electrical and magnetic circuit requirements are met.

[0116] The rotating shaft 813 can be integrally formed with the magnetic conductor 82, or it can be connected to the magnetic conductor 82 as a separate component. The rotating shaft 813 can pass through the rigid support 814, or it can be inserted into the corresponding rigid support 814 from opposite sides of the magnetic conductor 82. The axial direction of the rotating shaft 813 can be determined according to the required swing plane of the magnetic conductor 82, so that the magnetic conductor 82 can rotate in a direction that is compatible with the floating direction of the inner iron core 3.

[0117] The rotating shaft 813 and the rigid support 814 can be connected by a hole-shaft fit, a slot-shaft fit, or other methods that enable relative rotation. The rotating connection can also be provided with a limiting relationship to restrict the axial movement of the rotating shaft 813, but this limiting relationship should preferably not prevent the magnetic conductor 82 from rotating around the rotating shaft 813.

[0118] To achieve the same technical objective, the rigid support 814 can also be composed of multiple cooperating support parts, and the rotating shaft 813 can be supported between multiple support parts; the elastic strip 8121 can also be replaced by a strip-shaped, sheet-shaped, or flexible connection structure capable of elastic deformation. All the aforementioned equivalent deformations should maintain the basic structural relationship whereby the rigid support 814 is connected to the frame 811 via the elastic structure, and the magnetic conductor 82 is rotatably connected to the rigid support 814 via the rotating shaft 813.

[0119] The magnetic conductor 82 has a first end facing the inner iron core 3 and a second end facing the magnetic plate 6. When the coil 2 is energized, the first end contacts the inner iron core 3 under the magnetic attraction of the inner iron core 3, and the second end contacts the magnetic plate 6 under the magnetic attraction of the magnetic plate 6. When the inner iron core 3 floats relative to the magnetic plate 6, the elastic strip 8121 undergoes elastic deformation, and the magnetic conductor 82 rotates about the rotation axis 813 relative to the rigid support 814 to maintain the first end in contact with the inner iron core 3 and the second end in contact with the magnetic plate 6.

[0120] In this embodiment, the adaptive magnetic guiding component 8 is disposed between the inner iron core 3 and the magnetic guiding plate 6, including a frame 811 fixedly connected to the magnetic guiding plate 6, a rigid support 814 connected to the frame 811 via an elastic strip 8121, and a magnetic guiding body 82 rotatably connected to the rigid support 814. A rotating shaft 813 is provided on the magnetic guiding body 82, which is inserted into the rigid support 814 and can rotate relative to the rigid support 814, allowing the magnetic guiding body 82 to adjust its posture around the rotating shaft 813 as the rotation center. One end of the elastic strip 8121 is connected to the frame 811, and the other end is connected to the rigid support 814, providing elastic support to the rigid support 814 on the frame 811 and enabling corresponding elastic displacement when the magnetic guiding body 82 is subjected to force.

[0121] The magnetic conductor 82 has a first end facing the inner iron core 3 and a second end facing the magnetic guide plate 6. The first end is used to form a contact magnetic conduction engagement with the inner iron core 3, and the second end is used to form a contact magnetic conduction engagement with the magnetic guide plate 6. The magnetic conductor 82 is located between the inner iron core 3 and the magnetic guide plate 6, with its first end and second end facing the inner iron core 3 and the magnetic guide plate 6 respectively, so that the magnetic conductor 82 can bridge the inner iron core 3 and the magnetic guide plate 6 and constitute a magnetic flux transmission component between the two.

[0122] When coil 2 is not energized or the reactor has not yet entered the working state, the elastic strip 8121 provides elastic support to the magnetic conductor 82 through the rigid support 814, keeping the magnetic conductor 82 in a position close to the inner iron core 3 and the magnetic plate 6. At this time, the magnetic conductor 82 can maintain contact with the inner iron core 3 and the magnetic plate 6, or it can maintain a positional relationship that allows it to form contact due to magnetic attraction after energization. The initial position of the magnetic conductor 82 is preferably such that after coil 2 is energized, the first end can contact the inner iron core 3 and the second end can contact the magnetic plate 6.

[0123] When the reactor starts working, a working current is supplied to coil 2, which generates a magnetic field. The inner iron core 3 and the magnetic plate 6 are in the corresponding magnetic field state. The magnetic conductor 82 is made of a material that can transmit magnetic flux. Under the action of the magnetic field, the inner iron core 3 generates a magnetic attraction to the first end of the magnetic conductor 82, and the magnetic plate 6 generates a magnetic attraction to the second end of the magnetic conductor 82.

[0124] Under the aforementioned magnetic attraction, the magnetic conductor 82 adjusts its position and orientation based on the rotating shaft 813, causing its first end to move towards and contact the inner iron core 3, and its second end to move towards and contact the magnetic guide plate 6. After the two ends of the magnetic conductor 82 make contact, a continuous magnetic flux transmission path is formed between the inner iron core 3, the magnetic conductor 82, and the magnetic guide plate 6, allowing magnetic flux to be transmitted from the inner iron core 3 to the magnetic guide plate 6 via the magnetic conductor 82, or from the magnetic guide plate 6 to the inner iron core 3 via the magnetic conductor 82.

[0125] Since the magnetic conductor 82 is rotatably connected to the rigid support 814 via the rotating shaft 813, the magnetic conductor 82 can adjust its contact posture under magnetic attraction. Even if there is a certain positional deviation between the initial position of the magnetic conductor 82 and the corresponding surface of the inner iron core 3 or the magnetic plate 6, the magnetic conductor 82 can still rotate around the rotating shaft 813 to make the first end and the second end tend to contact the inner iron core 3 and the magnetic plate 6 respectively, thereby improving the adaptability of the magnetic conductor 82 in establishing a magnetic path.

[0126] During reactor operation, when the inner core 3 is subjected to external vibration, impact, or periodic force, the inner core 3 will elastically float relative to the magnetic plate 6 under the action of the elastic buffer component 7. Since the magnetic plate 6 and the frame 811 connected to the magnetic plate 6 remain relatively stable, the floating of the inner core 3 will cause a change in the relative position between the inner core 3 and the magnetic plate 6, and a corresponding change in the contact position between the first end of the magnetic conductor 82 and the inner core 3.

[0127] When the inner core 3 floats, the first end of the magnetic conductor 82 moves with the inner core 3 under the magnetic attraction and positional change of the inner core 3. The magnetic conductor 82 rotates relative to the rigid support 814 with the rotation shaft 813 as the center, so that the posture of the magnetic conductor 82 adapts to the changes in the distance or relative angle between the inner core 3 and the magnetic plate 6. At the same time, the force on the magnetic conductor 82 is transmitted to the rigid support 814 through the rotation shaft 813. The rigid support 814 drives the elastic strip 8121 to produce elastic deformation, so that the rotational support position of the magnetic conductor 82 can be adaptively adjusted relative to the frame 811.

[0128] Specifically, when the inner iron core 3 floats away from the magnetic plate 6, the first end of the magnetic conductor 82 moves accordingly with the inner iron core 3. The magnetic conductor 82 rotates around the rotation axis 813, and the elastic strip 8121 simultaneously produces elastic deformation that adapts to this movement, so as to compensate for the increased gap between the inner iron core 3 and the magnetic plate 6, so that the first end continues to contact the inner iron core 3 and the second end continues to contact the magnetic plate 6.

[0129] When the inner iron core 3 floats in the direction close to the magnetic plate 6, the position of the inner iron core 3 on the first end of the magnetic conductor 82 changes accordingly. The magnetic conductor 82 rotates in the opposite direction around the rotation axis 813. The elastic strip 8121 deforms accordingly according to the force state of the magnetic conductor 82 and the rigid support 814, thereby adapting to the reduced gap between the inner iron core 3 and the magnetic plate 6, and avoiding the magnetic conductor 82 forming a rigid obstacle to the floating of the inner iron core 3.

[0130] When the inner iron core 3 undergoes a certain degree of attitude change during floating, the magnetic conductor 82 can also change its tilt state by utilizing the rotational relationship between the rotating shaft 813 and the rigid support 814, while the elastic strip 8121 compensates for the position of the rigid support 814 through elastic deformation. Thus, the first end of the magnetic conductor 82 can follow the position change of the corresponding surface of the inner iron core 3, while the second end can maintain magnetic contact with the magnetic plate 6.

[0131] Throughout the floating process, the rotation of the magnetic conductor 82 and the deformation of the elastic strip 8121 work together. The magnetic conductor 82 rotates around the rotation axis 813, mainly to adjust its own angle and attitude; the elastic strip 8121 undergoes elastic deformation, mainly to adjust the position of the rigid support 814 and the rotation center of the magnetic conductor 82. Through the combined effect of attitude adjustment and position compensation, the magnetic conductor 82 can adapt to the floating of the inner iron core 3 relative to the magnetic plate 6, and maintain contact between its first end and the inner iron core 3 and its second end and the magnetic plate 6.

[0132] When the vibration or force acting on the inner iron core 3 weakens, the inner iron core 3 tends to return to its original position under the action of the elastic buffer component 7. The magnetic conductor 82 rotates in the opposite direction around the rotation axis 813 as the position of the inner iron core 3 changes, and the elastic strip 8121 also uses its own elastic restoring force to drive the rigid support 814 to tend to return to its original support position. During this process, the magnetic conductor 82 continues to be attracted by the magnetic attraction of the inner iron core 3 and the magnetic plate 6, keeping its two ends in contact.

[0133] Each of the core modules 31 is coaxially arranged, and each of the core modules 31 has a radial structure that extends outward along the radial direction of the inner core 3. Multiple core modules 31 are stacked sequentially along the axial direction of the inner core 3.

[0134] In this embodiment, the inner core 3 is composed of multiple core modules 31, each core module 31 being arranged around the axis of the inner core 3, and the axes of the multiple core modules 31 coinciding with each other, so that the core modules 31 are arranged coaxially. The multiple core modules 31 are stacked sequentially along the axial direction of the inner core 3, and an insulating spacer 32 is provided between adjacent core modules 31 to maintain the distance, thereby forming an air gap 33 between adjacent core modules 31.

[0135] Each core module 31 has a radial structure. The radial structure means that the magnetically conductive portion of the core module 31 is distributed around the axis of the inner core 3 and extends radially away from the axis, forming a structure that expands from the central region to the outer periphery on a cross-section perpendicular to the axis of the inner core 3. The axial center of each core module 31 corresponds to the axis of the inner core 3, thus allowing multiple radial core modules 31 to be arranged sequentially along the same axis.

[0136] The core module 31 is used to carry and transmit the magnetic flux generated by the coil 2 after it is energized. After the coil 2 is arranged around the inner core 3, the magnetic field generated by the coil 2 acts on multiple core modules 31 stacked along the axial direction. The magnetic flux is transmitted sequentially through each core module 31 and the air gap 33 between adjacent core modules 31. The core module 31 adopts a radial structure, which enables the magnetic conductive area of ​​the core module 31 to be distributed circumferentially and the magnetic flux to be transmitted within the radial range of the core module 31, so that the inner core 3 as a whole forms a magnetic conductive structure adapted to the coil 2.

[0137] Multiple core modules 31 are coaxially arranged so that the center positions of each core module 31 correspond along the axial direction of the inner core 3, reducing magnetic circuit misalignment caused by center offset between adjacent core modules 31. The radial regions of adjacent core modules 31 correspond to each other along the axial direction, so that when magnetic flux is transmitted from one core module 31 to an adjacent core module 31, it can pass through the corresponding magnetically conductive regions and the air gap 33 between them, reducing uneven magnetic flux distribution caused by eccentricity or misalignment of the core modules 31.

[0138] Multiple core modules 31 are stacked sequentially along the axial direction, enabling the inner core 3 to form a multi-segment magnetically conductive structure in the axial direction. Insulating spacers 32, disposed between adjacent core modules 31, serve two purposes: firstly, to separate adjacent core modules 31, and secondly, to limit the axial distance between adjacent core modules 31, thus forming a predetermined air gap 33 between each core module 31. Multiple air gaps 33 are distributed along the axial direction of the inner core 3, collectively adjusting the magnetic reluctance of the magnetic circuit containing the inner core 3.

[0139] For example, the core module 31 can be circular, approximately circular, or have an outer contour adapted to the internal space of the coil 2 in the direction perpendicular to the axis of the inner core 3, and its internal magnetic conductive portion extends radially outward to form a radial structure. The specific radial dimensions of the core module 31 can be determined according to the inner diameter of the coil 2, the required magnetic cross-sectional area, and the inductance requirements of the reactor.

[0140] Each core module 31 can have the same outer contour and radial dimension, so that multiple core modules 31 can be stacked along the axial direction to form an inner core 3 with a basically consistent outer contour; under the condition that multiple core modules 31 are coaxially arranged and can stably transmit magnetic flux along the axial direction, the radial dimension of each core module 31 can also be set according to the magnetic flux distribution or installation space.

[0141] The axial thickness of the core module 31 can be determined based on the total length of the inner core 3, the number of core modules 31, and the number of air gaps 33. Multiple core modules 31 can have the same axial thickness to create a more uniform modular structure along the axial direction of the inner core 3; alternatively, the axial thickness can be set according to the magnetic flux state or structural stress at different axial positions. These dimensional changes do not alter the fundamental relationship of multiple core modules 31 being coaxially arranged and stacked sequentially along the axial direction of the inner core 3.

[0142] The insulating spacer 32 between adjacent core modules 31 can mate with the axial end face of the core module 31 to form a relatively stable gap between adjacent core modules 31. The insulating spacer 32 can be set at one or more positions on the axial end face of the core module 31, as long as it can maintain the axial distance between adjacent core modules 31 and form an air gap 33.

[0143] It also includes an outer iron core 4, a bottom iron core 5, and an insulating layer 35. The outer iron core 4 is sleeved on the outside of the coil 2. The bottom iron core 5 is disposed at the same axial end of the inner iron core 3 and the outer iron core 4. The inner iron core 3, the outer iron core 4, and the bottom iron core 5 cooperate to form a magnetic circuit surrounding the coil 2. The magnetic guide plate 6 is disposed between the inner iron core 3 and the bottom iron core 5. The insulating layer 35 is disposed between the magnetic guide plate 6 and the bottom iron core 5 and is connected to the magnetic guide plate 6 and the bottom iron core 5 respectively.

[0144] In this embodiment, the reactor further includes an outer iron core 4, a bottom iron core 5, and an insulating layer 35. The inner iron core 3 is disposed inside the coil 2, and the outer iron core 4 is sleeved on the outside of the coil 2, so that the coil 2 is located between the inner iron core 3 and the outer iron core 4. The bottom iron core 5 is disposed at the same axial end of the inner iron core 3 and the outer iron core 4, and is respectively disposed corresponding to the inner iron core 3 and the outer iron core 4, so that the inner iron core 3, the outer iron core 4 and the bottom iron core 5 cooperate with each other to form a magnetic circuit surrounding the coil 2.

[0145] The outer iron core 4 forms a peripheral magnetic guiding structure on the outside of the coil 2 and, together with the inner iron core 3, defines the magnetic field area where the coil 2 is located. When the coil 2 is energized, the inner iron core 3 guides the magnetic flux inside the coil 2, and the outer iron core 4 guides the magnetic flux outside the coil 2. The bottom iron core 5 is located at the same end of the inner iron core 3 and the outer iron core 4, connecting the magnetic guiding area of ​​the inner iron core 3 with the magnetic guiding area of ​​the outer iron core 4 at this axial end. Thus, magnetic flux can be transmitted between the inner iron core 3, the bottom iron core 5, and the outer iron core 4, forming a magnetic flux transmission path that surrounds the coil 2.

[0146] A magnetic guide plate 6 is disposed between the inner iron core 3 and the bottom iron core 5. Specifically, the magnetic guide plate 6 is located on the side of the inner iron core 3 facing the bottom iron core 5, with one side of the magnetic guide plate 6 facing the inner iron core 3 and the other side facing the bottom iron core 5. Space is reserved between the inner iron core 3 and the magnetic guide plate 6 for the installation of the elastic buffer assembly 7 and the adaptive magnetic guide assembly 8, allowing the inner iron core 3 to float elastically relative to the magnetic guide plate 6, and maintaining the magnetic path between the inner iron core 3 and the magnetic guide plate 6 through the adaptive magnetic guide assembly 8.

[0147] An insulating layer 35 is disposed between the magnetic plate 6 and the bottom iron core 5. One side of the insulating layer 35 is connected to the magnetic plate 6, and the other side is connected to the bottom iron core 5. The insulating layer 35 is used to form an insulating barrier between the magnetic plate 6 and the bottom iron core 5, while supporting or mounting the magnetic plate 6 on one side of the bottom iron core 5, so that the magnetic plate 6 is kept in a predetermined position relative to the bottom iron core 5.

[0148] Under this connection, the bottom iron core 5 provides a mounting base for the magnetic plate 6 through the insulating layer 35. When the inner iron core 3 floats relative to the magnetic plate 6 due to vibration or force, the magnetic plate 6 can remain relatively stable under the support of the insulating layer 35 and the bottom iron core 5, thereby providing a stable reference for the elastic deformation of the elastic buffer assembly 7 and the activity of the adaptive magnetic assembly 8.

[0149] Viewed radially, the inner core 3 is located inside the coil 2, and the outer core 4 is located outside the coil 2. Viewed axially, the bottom core 5 is located at the same end of the inner core 3 and the outer core 4. The magnetic guide plate 6 and the insulating layer 35 are sequentially arranged between the inner core 3 and the bottom core 5. This structure allows the magnetic flux generated by the coil 2 to enter the inner core 3 and the outer core 4 respectively, and to achieve corresponding magnetic flux transmission through the bottom core 5.

[0150] When the reactor starts working, a working current is supplied to coil 2, generating a magnetic field around coil 2. The inner iron core 3 located inside coil 2 guides the magnetic flux inside coil 2, while the outer iron core 4, which is sleeved on the outside of coil 2, guides the magnetic flux outside coil 2. The bottom iron core 5, located at the same end of the inner iron core 3 and the outer iron core 4, receives the corresponding magnetic flux, thereby forming a magnetic circuit around coil 2 by the inner iron core 3, the outer iron core 4, and the bottom iron core 5.

[0151] At the end of the inner iron core 3 facing the bottom iron core 5, magnetic flux can be transmitted from the inner iron core 3 to the magnetic guide plate 6 via the adaptive magnetic guide component 8. The magnetic guide plate 6 is located between the inner iron core 3 and the bottom iron core 5, serving to receive the magnetic flux at the end of the inner iron core 3 and cooperating with the bottom iron core 5 in the transmission of magnetic flux. An insulating layer 35 is disposed between the magnetic guide plate 6 and the bottom iron core 5, maintaining their connection while providing insulation between the magnetic guide plate 6 and the bottom iron core 5.

[0152] When the reactor is subjected to external vibration or the inner core 3 is subjected to periodic force, the inner core 3 floats elastically relative to the magnetic plate 6 under the action of the elastic buffer component 7. Since the magnetic plate 6 is connected to the bottom core 5 through the insulating layer 35, the magnetic plate 6 can remain relatively stable; the adaptive magnetic guiding component 8 moves accordingly with the floating of the inner core 3 to maintain the magnetic path between the inner core 3 and the magnetic plate 6.

[0153] In the above process, the outer magnetic circuit structure formed by the outer iron core 4 and the bottom iron core 5 does not need to float synchronously with the inner iron core 3. The floating of the inner iron core 3 mainly occurs between the inner iron core 3 and the magnetic guide plate 6. Thus, while maintaining the relative stability of the outer magnetic circuit structure, the vibration acting on the inner iron core 3 can be reduced by the elastic buffer component 7, and the positional change of the inner iron core 3 can be compensated by the adaptive magnetic guide component 8.

[0154] When the vibration acting on the inner iron core 3 weakens, the inner iron core 3 tends to return to its original position under the restoring effect of the elastic buffer component 7, and the adaptive magnetic guiding component 8 performs corresponding activities to maintain the corresponding magnetic flux transmission state between the inner iron core 3, the magnetic guiding plate 6, the bottom iron core 5 and the outer iron core 4.

[0155] It also includes a forked connector 17, which has a first connector end electrically connected to the connector end of the coil 2 and a second connector end for electrically connecting to an external circuit, wherein a plurality of parallel conductive branches are formed between the first connector end and the second connector end.

[0156] In this embodiment, the reactor further includes a forked connector 17, which is disposed between the connector end of the coil 2 and the external circuit, for connecting the coil 2 to the corresponding power supply circuit or test circuit. The forked connector 17 has a first connection end and a second connection end. The first connection end is electrically connected to the connector end of the coil 2, and the second connection end is used to electrically connect to the external circuit, thereby establishing a current transmission path between the coil 2 and the external circuit.

[0157] Multiple conductive branches are provided between the first connection terminal and the second connection terminal, and these conductive branches are connected in parallel. One end of each conductive branch is electrically connected to the first connection terminal, and the other end is electrically connected to the second connection terminal, so that the current input from the first connection terminal can be distributed to the multiple conductive branches and then converged to the second connection terminal after passing through each conductive branch; in reverse transmission, the current can also be transmitted from the second connection terminal to the first connection terminal through the multiple parallel conductive branches.

[0158] The first connection terminal is used to establish a stable conductive connection with the connector of coil 2, allowing the current in coil 2 to be transmitted to the branched connection connector 17. The second connection terminal is used to establish a conductive connection with an external circuit, enabling the reactor to be connected to a predetermined electrical circuit. Multiple conductive branches are located between the first and second connection terminals, collectively responsible for the current transmission between coil 2 and the external circuit.

[0159] Multiple conductive branches are connected in parallel, with each branch connected to the same first and second connection terminals. When current flows through the branched connector 17, it is distributed to different conductive branches according to their impedance, with each branch sharing the total transmitted current. Compared to a connection structure that transmits current through a single conductive path, multiple parallel conductive branches reduce the current carried by a single conductive path and minimize current concentration in localized connection areas.

[0160] In this embodiment, the reactor further includes a housing structure 1, which includes an insulating cylinder 11, an insulating top cover 12, an insulating pull rod 13, a base 14, a pad 15, and a pressure plate 18. The insulating cylinder 11 is mounted on the base 14, and the insulating cylinder 11 and the base 14 together define an installation space for accommodating the internal components of the reactor. The insulating top cover 12 is disposed at the end of the insulating cylinder 11 facing away from the base 14 and covers the opening of the insulating cylinder 11, so that the coil 2, the inner iron core 3, and the corresponding magnetic conductive structure are accommodated within the space defined by the insulating cylinder 11, the insulating top cover 12, and the base 14.

[0161] The insulating cylinder 11 is used to circumferentially enclose the internal components of the reactor and form an insulating barrier between the internal components and the external environment. The base 14 is located at the bottom of the housing structure 1 and is used to support the insulating cylinder 11 and the internal reactor components disposed within the insulating cylinder 11. The insulating cover 12 is used to close the upper opening of the insulating cylinder 11, thereby reducing the possibility of foreign objects entering the housing structure 1, and together with the insulating cylinder 11, forms protection for the internal components.

[0162] The bottom iron core 5 is positioned above the base 14, and a pad 15 is provided between the bottom iron core 5 and the base 14. One side of the pad 15 corresponds to the base 14, and the other side supports the bottom iron core 5, maintaining a predetermined installation position between the bottom iron core 5 and the base 14. The pad 15 is used to transfer the load of the bottom iron core 5 to the base 14, and can be arranged according to the installation height and stress position of the bottom iron core 5 to provide stable support for the bottom iron core 5.

[0163] The inner iron core 3 is disposed inside the coil 2, the outer iron core 4 is sleeved on the outside of the coil 2, and the bottom iron core 5 is located at the same axial end of the inner iron core 3 and the outer iron core 4. The inner iron core 3, the outer iron core 4, and the bottom iron core 5 together define a placement space 16, within which the coil 2 is disposed. Specifically, the placement space 16 is located on the outside of the inner iron core 3, the inside of the outer iron core 4, and one side of the bottom iron core 5, allowing the coil 2 to be disposed around the inner iron core 3 and within the area enclosed by the outer iron core 4.

[0164] The placement space 16 is used to define the mounting position of the coil 2 relative to the inner iron core 3, the outer iron core 4, and the bottom iron core 5. On one hand, the inner iron core 3 is located inside the coil 2 to guide the magnetic flux inside the coil 2; on the other hand, the outer iron core 4 is located outside the coil 2 to guide the magnetic flux outside the coil 2; the bottom iron core 5 is disposed on one axial side of the coil 2 and cooperates with the inner iron core 3 and the outer iron core 4 to form a corresponding magnetic flux transmission path.

[0165] An insulating tie rod 13 is disposed within the housing structure 1 and cooperates with the base 14 and the pressure plate 18 to axially fix the internal components of the reactor. One end of the insulating tie rod 13 is connected to the base 14, and the insulating tie rod 13 extends axially along the housing structure 1. The pressure plate 18 is disposed at the end of the insulating tie rod 13 facing away from the base 14. The pressure plate 18 is connected to the insulating tie rod 13 and abuts against the internal components of the reactor axially above, so that the insulating tie rod 13 and the pressure plate 18 together exert a limiting effect on the internal components toward the base 14.

[0166] Through the cooperation of the insulating tie rod 13 and the pressure plate 18, the bottom iron core 5, outer iron core 4, coil 2, and their cooperating internal structures, which are set on the base 14, can be kept in the predetermined installation position within the housing structure 1. The insulating tie rod 13 is used to establish an axial connection between the base 14 and the pressure plate 18, and the pressure plate 18 is used to expand the effective area of ​​the internal components, so that the axial limiting effect on the internal components is relatively stable.

[0167] It should be noted that the insulating tie rod 13 and the fixing structure 34 used to connect multiple core modules 31 are different components. The insulating tie rod 13 is used to install and confine the internal components of the reactor within the housing structure 1, while the fixing structure 34 is used to connect multiple core modules 31 that make up the inner core 3 to restrict the relative movement between the core modules 31. The two have different installation positions and functions.

[0168] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
