Description

Technical Field

[0001] This invention relates to the field of reactor technology, specifically to a high-voltage reactor with a multi-stage vibration damping and noise reduction base. Background Technology

[0002] High-voltage reactors are crucial reactive power compensation devices in power systems, widely used to limit short-circuit currents, suppress harmonics, and improve power factors. However, during operation, the reactor core undergoes magnetostriction, and significant electromagnetic forces exist between the windings, leading to high-frequency mechanical vibrations. This vibration is directly transmitted to the foundation or floor slab through the base, causing structural noise. Furthermore, high-frequency vibration generates heat at the mounting base connections, reducing the strength of these connections and shortening the equipment's lifespan.

[0003] Currently, conventional high-voltage reactor bases mostly employ rigid connections or simple rubber vibration isolation. Rigid connections are almost incapable of blocking vibration transmission, while rubber alone, although providing some vibration isolation, has limited isolation capacity. Furthermore, relying solely on rubber pads for vibration damping is prone to material aging and creep, leading to a gradual deterioration or even failure of the damping effect over long-term use. In addition, some designs use springs as vibration isolation elements, but springs sometimes resonate with the reactor's vibration, causing an increase in the reactor's vibration amplitude.

[0004] As the demand for electricity in residential use continues to increase, single vibration reduction methods are no longer sufficient to reduce the vibration of high-voltage reactors.

[0005] To address this, a high-voltage reactor with a multi-stage vibration damping and noise reduction base is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a high-voltage reactor with a multi-stage vibration damping and noise reduction base to solve the problem that a single vibration damping method cannot effectively reduce reactor vibration.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A high-voltage reactor with a multi-stage vibration-damping and noise-reducing base includes a reactor body and a vibration-damping base. The reactor body includes an upper support, a lower support, an iron core, and a coil. The iron core is disposed between the upper and lower supports, and the coil is wound around the iron core. The vibration-damping base includes a circular sleeve with a hollow interior forming an installation cavity. Multiple support legs are provided on the side wall of the sleeve, and bolt holes are provided on the support legs. A transmission rod is fixedly connected to the bottom of the lower support. The transmission rod passes through the top of the sleeve and extends into the installation cavity. One end of the transmission rod extending into the installation cavity is fixed with a... A conductive disk is slidably connected to a mounting cavity. A first rubber ring is wound around the bottom sidewall of the conductive disk, and the first rubber ring is sealed and fitted to the inner sidewall of the mounting cavity. A sealed chamber is formed between the conductive disk and the bottom of the mounting cavity. Multiple first permanent magnets are fixedly installed at the bottom of the conductive disk, and multiple second permanent magnets are arranged at the bottom of the mounting cavity corresponding to the multiple first permanent magnets. The magnetic poles of each first permanent magnet and the corresponding second permanent magnet are the same on the side facing each other. The second permanent magnets repel the first permanent magnets, so that a gap is formed between the bottom surface of the conductive disk and the bottom surface of the mounting cavity.

[0008] By setting up a first rubber ring, a first permanent magnet, and a second permanent magnet, the first rubber ring mitigates horizontal vibrations, while the magnetic force between the first and second permanent magnets, along with the air pressure within the sealed chamber, allows the conduction disk and reactor body to achieve a near-suspended state, thus mitigating vertical vibrations and creating a multi-stage vibration reduction effect. Using magnetism instead of traditional springs for levitation also avoids the risk of resonance between the spring and the reactor. Furthermore, the conduction disk only contacts the mounting cavity through the first rubber ring, resulting in a small contact area that effectively reduces vibration transmission to the sleeve and floor slab. This reduces the contact area and vibration transmission path between the reactor body and the foundation, minimizing heat damage to the connection points caused by vibration.

[0009] Compared to existing single vibration reduction methods, multi-stage vibration reduction can more effectively reduce reactor vibration and reduce the noise generated by reactor vibration transmitted to the foundation such as floor slabs.

[0010] Preferably, a sealed liquid cavity is formed inside the side wall of the sleeve, the liquid cavity is connected to the sealed chamber, both the sealed chamber and the liquid cavity are filled with silicone oil, and an air section is formed on the upper side of the liquid cavity to accommodate air.

[0011] By incorporating silicone oil and air components, the silicone oil provides auxiliary support to the conduction disk, reducing the demand for permanent magnet magnetic force and lowering equipment design costs. Simultaneously, when the conduction disk moves horizontally, the viscosity of the silicone oil adheres to the bottom of the disk, generating reverse resistance, which, together with the elastic restoring force of the first rubber ring, suppresses horizontal vibration.

[0012] The air section provides compression space for the almost incompressible silicone oil, preventing hydraulic pressure from causing the conduction disk to lock up during up-and-down vibration and resulting in a hard impact between the conduction disk and the silicone oil. In addition, when the vibration of the reactor body is transmitted to the sleeve side wall through the first rubber ring, the solid vibration energy of the sleeve side wall can be converted into heat energy and dissipated through the internal friction of the silicone oil, further weakening the residual vibration transmitted to the foundation. The liquid cavity, as an additional damping layer, can also suppress the vibration noise generated by the collision between the first rubber ring and the sleeve side wall, reducing the sound inside the sleeve transmitted to the outside air.

[0013] Preferably, a conductive plate is fixedly installed at the bottom of the conductive disk. The conductive plate is annular and has a trumpet shape with the larger end facing downwards. The conductive plate is concentrically arranged with the conductive disk.

[0014] By incorporating conductive plates, when the reactor experiences high-frequency vibration, the plates vibrate rapidly with relatively small amplitude. The silicone oil near the edge of the conductive plates is forced to generate a high-velocity gradient due to edge shearing, significantly enhancing viscous shear dissipation. This helps to quickly convert the mechanical energy generated by vibration into the internal energy of the silicone oil, thus reducing high-frequency vibration and consequently lowering noise caused by equipment vibration. At low frequencies, the horn-shaped conductive plates vibrate with larger amplitude. Stirring the silicone oil, both vertically and horizontally, the viscosity of the silicone oil reduces the vibration amplitude, making the equipment more stable during low-frequency vibrations.

[0015] Preferably, each of the conductive sheets has multiple flow holes, which are evenly arranged on the conductive sheet.

[0016] By incorporating flow-through orifices, a significant velocity gradient is generated at the edges of multiple orifices during high-frequency vibration. This further enhances viscous shear dissipation, converting a large amount of mechanical kinetic energy into the internal energy of the silicone oil, effectively reducing equipment vibration. Simultaneously, the throttling effect of the flow-through orifices ensures greater stability during low-frequency vibrations with large amplitudes.

[0017] Preferably, the cross-section of the first rubber ring is Y-shaped, with the opening of the Y-shaped cross-section facing the direction of the sealed cavity.

[0018] By setting the cross-section of the first rubber ring to a "Y" shape, when the transmission disk moves downward, the pressure of the silicone oil allows the first rubber ring to fit better with the mounting cavity, preventing the silicone oil from flowing onto the transmission disk, improving the reliability of the seal, and ensuring the stability of the vibration reduction effect during long-term operation.

[0019] Preferably, an annular groove is provided at the position where the top of the sleeve contacts the guide rod, and a second rubber ring is provided in the annular groove, the second rubber ring having a circular cross-section.

[0020] By installing a second rubber ring, a straight line is defined by two points to ensure the transmission rod remains vertical. This prevents abnormal friction between the transmission plate and the mounting cavity due to rod misalignment, thus avoiding damage to the reactor body caused by tilting. Simultaneously, the elasticity of the rubber absorbs minor vibrations transmitted by the transmission rod, further enhancing the overall vibration reduction effect.

[0021] Preferably, the larger end of the conductive sheet is provided with an arc-shaped guide ring, which curves upward in an arc.

[0022] When the conduction disk vibrates at low frequencies, the downward distance of the conduction disk increases. The downward movement is hindered by magnetic force and the pressure of air and liquid, resulting in a relatively gentle downward motion after multiple vibration damping processes. However, when the conduction disk moves upward, the magnetic force and the pressure of liquid and air become the thrust for upward movement, causing the conduction disk to move too quickly and further increasing the amplitude of equipment sway, which is detrimental to the stable operation of the equipment.

[0023] By adding a guide ring, the conductive plate can hold the silicone oil as it moves upward with the conductive plate. The silicone oil generates a downward reaction force on the guide ring, which in turn forms a reverse damping on the upward movement of the conductive plate, preventing excessive swaying of the conductive plate and the reactor body, and ensuring stable operation of the equipment.

[0024] Simultaneously, the silicone oil propelled by the upward movement of the guide ring generates localized eddies within the annular region, further dissipating vibration energy and reducing vibration amplitude. Furthermore, the guide ring is responsible for gathering the silicone oil and increasing the flow velocity and pressure at the inlet of the flow orifice, while the flow orifice exerts a throttling and damping effect on the high-speed inflow of silicone oil. During the forced flow of the silicone oil through the small flow orifice, intense viscous shear and internal friction occur at the orifice edge, efficiently converting the mechanical energy of the rising conduction disk into heat energy for dissipation.

[0025] Preferably, the conductive sheet has multiple deformation grooves located on the side of the conductive sheet away from the fixed end. The multiple deformation grooves are evenly distributed on the conductive sheet with the center of the conductive sheet as the reference circumference, and the deformation grooves divide the large end of the conductive sheet into multiple fan shapes.

[0026] By setting deformation grooves, when the conductive sheet may collide downwards with the bottom of the mounting cavity during low-frequency, large-amplitude vibrations, the deformation grooves provide deformation space for the conductive sheet, preventing it from being torn and damaged, and extending the service life of the conductive sheet. At the same time, the deformation grooves increase the edge length of the conductive sheet, further enhancing the shearing effect with the silicone oil during high-frequency vibrations, generating more velocity gradients, and more effectively reducing the transmission of high-frequency vibrations to the floor slab.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The high-voltage reactor with a multi-stage vibration reduction and noise reduction base designed in this invention forms a magnetic gap between the first permanent magnet and the second permanent magnet, allowing the reactor body to form a state similar to suspension. Multi-stage vibration reduction in the vertical direction is achieved through magnetic force and fluid damping. At the same time, multi-stage vibration reduction in the horizontal direction is also achieved by utilizing the elasticity of the first rubber ring and the damping of the liquid, effectively reducing the vibration and noise generated during reactor operation.

[0028] 2. The high-voltage reactor with a multi-stage vibration reduction and noise reduction base designed in this invention uses a trumpet-shaped conductive plate with flow holes and an arc-shaped guide ring at the bottom of the conductive plate. During high-frequency vibration, the mechanical energy is converted into heat energy by the viscous shear of the silicone oil flowing through the edge of the hole and dissipated, further reducing the vibration of the equipment. When the conductive plate rises, the guide ring holds the silicone oil to generate reverse damping, making the equipment more stable during low-frequency vibration, thus achieving effective vibration reduction for different frequencies and directions of motion.

[0029] 3. The high-voltage reactor with a multi-stage vibration reduction and noise reduction base designed in this invention also achieves pressure adaptive sealing by setting a first rubber ring with a Y-shaped cross section, while setting a deformation groove to avoid overload tearing of the conductive plate, and using a second rubber ring to ensure the centering of the conductive rod, which significantly improves the structural reliability and service life of the base under long-term high-frequency vibration.

[0032] Please see Figures 1 to 6 This invention provides a high-voltage reactor with a multi-stage vibration damping and noise reduction base, the technical solution of which is as follows: A high-voltage reactor with a multi-stage vibration damping and noise reduction base, reference Figure 1 , Figure 2 and Figure 5 The reactor body 1 includes a reactor body 1 and a vibration damping base 2. The reactor body 1 includes an upper support 101, a lower support 102, an iron core 103 and a coil 104. The iron core 103 is disposed between the upper support 101 and the lower support 102, and the coil 104 is wound on the iron core 103.

[0033] refer to Figure 1 , Figure 4 and Figure 5 The vibration damping base 2 includes a circular sleeve 201. The sleeve 201 is hollow and forms an installation cavity 202. Multiple support legs 203 are provided on the side wall of the sleeve 201, and bolt holes 204 are provided on the support legs 203.

[0034] refer to Figure 5 and Figure 6 A guide rod 3 is fixedly connected to the bottom of the lower bracket 102. The guide rod 3 passes through the top of the sleeve 201 and extends into the mounting cavity 202. An annular groove 15 is also provided at the position where the top of the sleeve 201 contacts the guide rod 3. A second rubber ring 16 is provided in the annular groove 15. The cross-section of the second rubber ring 16 is circular. A guide disk 4 is fixed to one end of the guide rod 3 that extends into the mounting cavity 202. The guide disk 4 is slidably connected to the mounting cavity 202. A first rubber ring 5 is wound around the bottom side wall of the guide disk 4. The first rubber ring 5 is sealed and fitted to the inner side wall of the mounting cavity 202, forming a sealed chamber 6 between the guide disk 4 and the bottom of the mounting cavity 202. The cross-section of the first rubber ring 5 is "Y"-shaped, and the opening of the "Y"-shaped cross-section faces the direction of the sealed chamber 6. Multiple first permanent magnets 7 are fixedly installed at the bottom of the conduction disk 4. Multiple second permanent magnets 8 are provided at the bottom of the mounting cavity 202 corresponding to the multiple first permanent magnets 7. The magnetic poles of each first permanent magnet 7 and the corresponding second permanent magnet 8 are the same on the side facing each other. The second permanent magnet 8 repels the first permanent magnet 7 and forms a gap 9 between the bottom surface of the conduction disk 4 and the bottom surface of the mounting cavity 202.

[0035] refer to Figure 5 and Figure 6 The sleeve 201 has a sealed liquid cavity 10 inside its side wall. The liquid cavity 10 is connected to the sealed chamber 6 by multiple connecting holes. Both the sealed chamber 6 and the liquid cavity 10 are filled with silicone oil 11. When the silicone oil 11 is filled, a space is reserved at the top of the liquid cavity 10 to form an air section 12 for containing air.

[0036] refer to Figure 2 , Figure 3 as well as Figure 5 and Figure 6 A conductive plate 13 is fixedly installed at the bottom of the conductive disk 4. The conductive plate 13 is annular and flared with its larger end facing downwards. The conductive plate 13 is concentrically arranged with the conductive disk 4. Multiple flow holes 14 are evenly distributed on the conductive plate 13. An arc-shaped guide ring 17 is provided at the larger end of the conductive plate 13, curving upwards. Multiple deformation grooves 18 are provided on the conductive plate 13, located on the side of the conductive plate 13 away from the fixed end. The multiple deformation grooves 18 are evenly distributed circumferentially on the conductive plate 13 with the center of the conductive plate 13 as the reference, dividing the larger end of the conductive plate 13 into multiple fan shapes.

[0037] Working principle: When installing this device, refer to... Figure 1 , Figure 4 as well as Figure 5 and Figure 6 The reactor body 1 is fixed to the floor slab or foundation via the support feet 203 and bolt holes 204 on the side wall of the sleeve 201. The lower bracket 102 of the reactor body 1 is fixedly connected to the conduction rod 3. The conduction rod 3 passes through the top of the sleeve 201 and drives the conduction disk 4 to suspend in the mounting cavity 202. In a static equilibrium state, the conduction disk 4 is subjected to the downward gravity of the reactor body 1, the upward magnetic repulsion between the first permanent magnet 7 and the second permanent magnet 8, the upward hydraulic support force of the silicone oil 11 in the sealed cavity 6, and the support force of the air pressure in the air section 12. The four forces are balanced, so that a stable gap 9 is maintained between the bottom surface of the conduction disk 4 and the bottom surface of the mounting cavity 202.

[0038] When the reactor operates and generates vertical vibration, refer to Figure 5 and Figure 6The vibration is transmitted from the reactor body 1 through the lower support 102 and the transmission rod 3 to the transmission disk 4. The transmission disk 4 generates small vertical and horizontal displacements within the mounting cavity 202. In the vertical direction, when the transmission disk 4 moves downward, the magnetic repulsion between the first permanent magnet 7 and the second permanent magnet 8 increases. At the same time, the silicone oil 11 and the air section 12 in the sealed chamber 6 are compressed, generating an upward reaction force. The three together form a vertical buffer resistance, reducing the vibration amplitude of the equipment through multi-stage vibration reduction. When the conduction disk 4 moves upward, the magnetic repulsion decreases, and the compressed silicone oil and air section 12 expand and release energy. However, the upward thrust may cause the conduction disk 4 to rise too quickly. At this time, the guide ring 17 moves upward with the conduction plate 13, holding the silicone oil 11. The silicone oil generates a downward reaction force on the guide ring 17, forming upward damping, thereby suppressing the conduction disk 4 from rising too quickly and effectively attenuating the vertical vibration. When the guide ring 17 holds the silicone oil 11 and moves upward, the silicone oil 11 can form a small-range vortex at the arc-shaped guide ring 17, thereby converting the mechanical energy of the conduction disk 4 into the kinetic energy of the vortex flow. Furthermore, the guide ring 17 guides the silicone oil 11 to the flow hole 14 on the conduction plate 13, allowing the silicone oil 11 to pass through the flow hole 14. When the silicone oil 11 passes through the flow hole 14, the molecules squeeze and rub against each other, which can also consume the kinetic energy of the upward movement of the conduction disk 4, reduce the upward movement amplitude of the conduction disk 4 and the entire reactor body 1, and ensure the stability of the equipment when vibrating in the vertical direction.

[0039] In the horizontal direction, refer to Figure 5 and Figure 6 When the conduction disk 4 moves horizontally, the first rubber ring 5 collides with the inner wall of the mounting cavity 202. The first rubber ring 5 converts the kinetic energy in the horizontal direction into the internal energy of the deformation through deformation. In addition, the silicone oil 11 at the bottom of the conduction disk 4 generates reverse resistance on the conduction plate 13 and the bottom surface of the conduction disk 4 due to its viscosity. Together with the elasticity of the rubber ring, it achieves multi-stage vibration reduction in the horizontal direction.

[0040] When the reactor generates high-frequency vibration, reference Figure 5 and Figure 6 The conductive plate 13 moves at high frequency and small amplitude with the conductive disk 4. The edge of the trumpet-shaped conductive plate 13 is sheared at high speed in the silicone oil 11, which generates an extremely high velocity gradient in the silicone oil. The viscous shear energy dissipates the vibration mechanical energy into the heat energy of the silicone oil 11. At the same time, when the silicone oil flows through the flow hole 14 on the conductive plate 13 and the edge of the deformation groove 18, it generates more intense viscous shear and internal friction at the edge of the hole, which again converts the mechanical energy into heat energy for dissipation. This effectively absorbs the high-frequency vibration energy and reduces the residual vibration transmitted to the sleeve 201 and the floor slab.

[0041] When the reactor generates low-frequency, large-amplitude vibrations during operation, the conduction disk 4 moves with a large amplitude, and the horn-shaped conduction plate 13 also vibrates with a large amplitude. However, the movement speed of the conduction disk 4 and the conduction plate 13 is relatively slow. The conduction plate 13 continuously agitates the silicone oil, and the resistance generated by the viscosity of the silicone oil reduces the amplitude of the low-frequency vibration, making the equipment more stable during low-frequency vibrations. At the same time, the deformation groove 18 on the conduction plate 13 provides deformation space when the conduction plate 13 may collide with the bottom of the mounting cavity 202, preventing the conduction plate 13 from tearing and ensuring long-term reliable operation of the equipment.

[0042] In addition, refer to Figure 6 The second rubber ring 16 is positioned between the top of the sleeve 201 and the transmission rod 3. On one hand, it provides two-point support to ensure that the transmission rod 3 remains vertically aligned, preventing the transmission disc 4 from tilting and rubbing against it, and also preventing the reactor body 1 from tilting during operation and colliding with other equipment. On the other hand, the elastic deformation of the rubber in the second rubber ring 16 can absorb the minor vibrations transmitted from the transmission rod 3 to the sleeve 201, further improving the vibration isolation effect.

[0043] When the vibration of the reactor is transmitted to the side wall of the sleeve 201 through the first rubber ring 5, the reference... Figure 6 The solid vibration energy of the sleeve 201 sidewall is transferred to the silicone oil 11 in the liquid cavity 10. The internal friction between the silicone oil molecules converts the mechanical energy into heat energy, which is finally dissipated into the environment through the outer wall of the sleeve 201. At the same time, the liquid cavity 10, as an additional damping layer, can also suppress the noise generated by the collision between the first rubber ring 5 and the sidewall of the sleeve 201, reducing the sound inside the sleeve 201 transmitted to the outside air.

[0044] Finally, regarding sealing, refer to Figure 6 The first rubber ring 5 has a Y-shaped cross-section with its opening facing the sealed chamber 6. When the transmission disk 4 moves downward, the silicone oil pressure in the sealed chamber 6 increases. The oil pressure acts on the inside of the Y-shaped opening, making the lip of the rubber ring fit more tightly against the inner wall of the mounting cavity 202, preventing silicone oil from leaking above the transmission disk 4.

[0045] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
