Description

TECHNICAL FIELD

[0001] The present application relates to a smoothing reactor, in particular to an anti-seismic type insulation resin cast type smoothing reactor, and also relates to a use method, in particular to a use method of an anti-seismic type insulation resin cast type smoothing reactor, and belongs to the technical field of reactors. BACKGROUND

[0002] The smoothing reactor is generally used in a high-voltage direct-current power transmission system, and mainly functions to smooth ripples in a direct-current current, reduce harmonics, and protect a converter and other devices. Since the smoothing reactor is large in size and heavy in weight, and is usually installed in an open area of an outdoor substation or a converter station, is exposed to a complex natural environment for a long time, and needs to withstand high and low temperatures, humidity changes and other tests, the anti-seismic performance is a core index to ensure that the smoothing reactor is not damaged in an earthquake disaster.

[0003] However, the anti-seismic design of the traditional smoothing reactor still stays at a single passive shock absorption level, and generally only realizes anti-seismic protection through a spiral spring shock absorber installed at the bottom. Although this structure can buffer the vibration impact in the vertical direction to a certain extent (test data shows that the vertical acceleration response can be reduced by about 30%), the limitation is particularly prominent for the smoothing reactor which is a precision device highly sensitive to multi-directional vibration. The design can only buffer the vibration in the vertical direction, and has weak inhibitory effect on the vibration in the horizontal direction and the torsion direction. However, the horizontal vibration acceleration in an actual earthquake is usually 1.5-2 times that in the vertical direction, which is easy to cause the gravity center of the smoothing reactor to deviate, and cause problems such as bending of the insulation support and fracture of the winding lead, in addition, the spring is easy to appear fatigue relaxation after long-term operation, and its stiffness will decrease by 15%-20%, further weakening the anti-seismic ability, so that the traditional anti-seismic method is difficult to meet the protection demand in a high-intensity seismic area.

[0004] Therefore, an anti-seismic type insulation resin cast type smoothing reactor and a use method are designed to optimize the above problems. SUMMARY

[0005] The main objective of this invention is to provide an earthquake-resistant, resin-cast smoothing reactor and its usage method. Through the cooperation of a longitudinal and a horizontal damping mechanism, it can specifically buffer vibrations in both vertical and horizontal directions. Simultaneously, the rocker arm, ball bearings, and slider at the top of the reactor body form a dynamic adjustment structure. Combined with the non-contact damping generated by the eddy current effect using the permanent magnet and eddy current plate at the bottom, these three elements work synergistically to comprehensively cover vertical, horizontal, and torsional vibrations, effectively addressing complex vibration patterns during earthquakes. This overcomes the limitation of traditional single passive damping, which can only buffer vertical vibrations. Furthermore, the non-contact damping design further weakens vibration transmission, forming a composite damping mechanism with the mechanical damping structure, significantly improving the dissipation of vibration energy. This design improves efficiency and avoids the fatigue and relaxation problems common with traditional helical springs, significantly extending the durability of the equipment's vibration resistance. The slider incorporates a rotating resistance mechanism consisting of a movable groove, column, collar, slide, resistance block, third spring, and pull rope. The column is fixed to the top of the ball, increasing the ball's rotational resistance through contact between the resistance block and the ball's surface when the ball swings significantly, effectively reducing the reactor's offset. Simultaneously, a center-of-gravity adjustment mechanism consisting of a fixed plate, strip groove, counterweight, and second connecting rod between the slider and the reactor body dynamically adjusts the overall center of gravity when the reactor body swings, further improving equipment stability and reducing the risk of structural damage such as bending of the insulating support and breakage of the winding leads.

[0052] The top of the carrier plate 2 is symmetrically provided with a support 4 at both ends, the top of the support 4 is horizontally fixed with a top plate 5, the bottom of the top plate 5 is horizontally slidably provided with a sliding block 6, and the outer side of the sliding block 6 and the inner side of the top plate 5 are provided with a horizontal damping mechanism 7, when encountering horizontal vibration, the sliding block 6 drives the horizontal damping mechanism 7 to deform and buffer;

[0053] The bottom end of the sliding block 6 is provided with a spherical groove 601, the inside of the spherical groove 601 is rotatably installed with a ball 8, the bottom of the ball 8 is vertically fixed with a pendulum rod 9, the bottom end of the pendulum rod 9 is fixed with a reactor body 10, and the pendulum rod 9 is located at the center position of the top of the reactor body 10, and the winding outside of the reactor body 10 is mixed with a curing agent (methyl tetrahydrophthalic anhydride) in a mass ratio of 100:30, and 5%-10% of silicon powder (particle size 5-10 μm) is added to enhance the thermal conductivity;

[0054] The bottom end of the reactor body 10 is horizontally fixed with a permanent magnet 13, the permanent magnet 13 is made of N35 neodymium iron boron permanent magnet, the thickness is 10-15 mm, the surface is nickel plated, the residual magnetism is 1.2-1.3 T, and the working temperature is ≤80℃;

[0055] The top of the carrier plate 2 is provided with an eddy current plate 14 at the middle position, the eddy current plate 14 is made of T2 red copper plate, the thickness is 5-8 mm, the surface is anodized, and the gap with the permanent magnet 13 is kept at 5-10 mm, when the reactor body 10 generates a relative speed of ≥0.1 m / s due to vibration, the magnetic field change between the permanent magnet 13 and the eddy current plate 14 generates eddy current, the eddy current magnetic field interacts with the magnetic field of the permanent magnet 13 to form damping force, the damping force is proportional to the relative speed (proportion coefficient 0.5-2 N・s / m), and 50%-70% of the torsional vibration energy can be consumed;

[0056] The inside of the sliding block 6 is provided with a rotary resistance mechanism 11, which is used to reduce the amplitude of the pendulum of the ball 8, when torsion or swing occurs, the rotary resistance mechanism 11 increases the rotation resistance of the ball 8 to reduce the swing amplitude;

[0057] The bottom end of the sliding block 6 and the reactor body 10 are provided with a gravity center adjusting mechanism 12, which is used to dynamically adjust the gravity center of the reactor body 10, when torsion or swing occurs, the gravity center adjusting mechanism 12 dynamically adjusts the gravity center of the reactor body 10 to maintain stability.

[0058] In the embodiment, the longitudinal damping mechanism 3 comprises first springs 301 and dampers 302, the first springs 301 are arranged in a rectangular array at the four corners of the bottom of the carrier plate 2, and the dampers 302 are installed at the middle positions of the base 1 and the carrier plate 2.

[0059] Local working principle: when the equipment encounters vertical vibration, the carrier plate 2 moves up and down relative to the base 1, the first springs 301 at the four corners generate elastic force through compression or stretching to directly buffer the impact energy in the vertical direction, and the dampers 302 in the middle generate damping force through the viscous resistance of the internal damping medium when the carrier plate 2 moves up and down, thereby converting the mechanical energy of vibration into heat energy consumption, avoiding continuous vibration of the first springs 301 due to resonance, and reducing the transmission strength of the vertical vibration to the reactor body 10.

[0060] In the embodiment, the inside of the top plate 5 is provided with a hollow cavity 501, the middle position of the bottom end of the hollow cavity 501 is provided with a through port 502 communicated with the bottom of the top plate 5, the cross-sectional shape of the slider 6 is T-shaped, the top end of the slider 6 is slidingly arranged inside the hollow cavity 501, and the bottom end of the slider 6 passes out of the through port 502.

[0061] Local working principle: the hollow cavity 501 inside the top plate 5 provides horizontal sliding space for the slider 6, the through port 502 at the bottom end allows the bottom end of the slider 6 to pass out and connect the reactor body 10, the slider 6 is T-shaped, the top end is embedded in the hollow cavity 501, and the bottom end extends to below the top plate 5 through the through port 502, this structure not only limits the vertical displacement of the slider 6, but also ensures that the slider 6 can freely move with horizontal vibration, at the same time, the through port 502 plays a guiding role in the horizontal sliding of the slider 6, avoiding the deviation of the slider 6 from the preset track, and ensuring that the horizontal damping mechanism 7 can stably respond to the vibration in the horizontal direction.

[0062] In the embodiment, the horizontal damping mechanism 7 comprises a sleeve 701, a piston 702, a second spring 703 and a first connecting rod 704, the sleeve 701 is hingedly installed on the inner wall of the hollow cavity 501, the piston 702 is slidingly installed inside the sleeve 701, the second spring 703 is arranged between the two sides of the piston 702 and the end portions of the sleeve 701, the first connecting rod 704 is fixed to one side of the piston 702 close to the opening of the sleeve 701, and the first connecting rod 704 extends to the outside of the sleeve 701 and is hingedly connected to the outside of the slider 6.

[0063] Local working principle: when the device encounters horizontal vibration, the reactor body 10 drives the sliding block 6 to move in the horizontal direction, the sliding block 6 pushes the first connecting rod 704, and the piston 702 slides in the sleeve 701. When the piston 702 slides, the second spring 703 on both sides of the piston 702 generates elastic force due to extrusion or stretching, and the elastic deformation buffers the impact energy in the horizontal direction. The hinged structure of the sleeve 701 and the top plate 5 and the first connecting rod 704 and the sliding block 6 ensures that the horizontal damping mechanism 7 can adapt to the movement of the sliding block 6 in different horizontal directions, and realizes the buffering of multi-directional horizontal vibration.

[0064] In this embodiment, the horizontal damping mechanism 7 is provided with six groups, and the included angles between adjacent horizontal damping mechanisms 7 are the same.

[0065] Local working principle: the six groups of mechanisms work together to cover 360° horizontal vibration in all directions, ensuring that no matter which horizontal angle the vibration comes from, it can be effectively buffered by the corresponding horizontal damping mechanism 7, improving the absorption efficiency of horizontal vibration.

[0066] In this embodiment, the rotary resistance mechanism 11 includes a sliding groove 1104, a resistance block 1105, a third spring 1106, and a release assembly. The sliding groove 1104 is evenly arranged in an annular array on the inner side of the spherical groove 601. The resistance block 1105 is slidably arranged in the sliding groove 1104. The resistance block 1105 and the sliding groove 1104 are provided with the third spring 1106, and the third spring 1106 is in a compressed state. The top of the spherical groove 601 is provided with a release assembly for releasing the elastic force of the third spring 1106.

[0067] Local working principle: in the initial state, the third spring 1106 is in a compressed state, but the resistance block 1105 does not contact the ball 8 through the constraint of the release assembly. When the reactor body 10 swings due to vibration, the ball 8 rotates in the spherical groove 601. The release assembly releases the constraint of the corresponding side resistance block 1105. The compressed third spring 1106 pushes the resistance block 1105 to move along the sliding groove 1104 towards the ball 8, so that the resistance block 1105 contacts the surface of the ball 8 and generates friction force, increasing the rotational resistance of the ball 8, thereby reducing the swing amplitude of the reactor body 10 and avoiding excessive deviation.

[0068] In this embodiment, the release assembly includes a movable groove 1101, a stand 1102, a sleeve ring 1103, and a pull rope 1107. The movable groove 1101 is arranged at the middle position of the top of the spherical groove 601. The top of the ball 8 is vertically fixed with the stand 1102. The top end of the stand 1102 extends into the inside of the movable groove 1101, and the top end of the stand 1102 is horizontally rotatably installed with the sleeve ring 1103. The side edges of the sleeve ring 1103 are fixed with the pull rope 1107, and the pull rope 1107 is fixed at the end of the resistance block 1105. The pull rope 1107 slides in the inside of the sliding block 6.

[0069] Local working principle: when the ball 8 rotates with vibration, the column 1102 fixed on the top of the ball 8 rotates synchronously and offsets in the movable slot 1101, the collar 1103 at the top of the column 1102 moves synchronously, the collar 1103 is connected with each resistance block 1105 through the pull rope 1107, when the ball 8 swings in a direction, the collar 1103 pulls the pull rope 1107 in the swing direction, so that the corresponding resistance block 1105 compresses the third spring 1106 and does not contact the ball 8, while the pull rope 1107 in the opposite direction is relaxed, the third spring 1106 pushes the resistance block 1105 on the side to contact the ball 8, and the swing amplitude is accurately reduced through the friction force to hinder the rotation of the ball 8, realizing the dynamic resistance adjustment of "accumulating force on the swing side and resisting on the opposite side".

[0070] In this embodiment, the bottom end of the resistance block 1105 is provided with a rubber pad, and the bottom of the rubber pad is provided with anti-skid lines.

[0071] Local working principle: the rubber pad at the bottom end of the resistance block 1105 has high friction coefficient and elasticity, when the resistance block 1105 contacts the surface of the ball 8, the rubber pad increases the contact area with the ball 8 through deformation, enhances the friction force to increase the rotation resistance, the anti-skid lines at the bottom of the rubber pad further increase the surface roughness, avoid the relative sliding between the resistance block 1105 and the ball 8, ensure the stable effect of the friction force, at the same time, the elasticity of the rubber can buffer the instantaneous impact force when contacting, avoid the wear of the resistance block 1105 and the ball 8 due to rigid contact, prolong the service life of the components.

[0072] In this embodiment, the gravity center adjusting mechanism 12 includes a fixed plate 1201, a strip-shaped slot 1202, a counterweight 1203 and a second connecting rod 1204, the fixed plate 1201 is fixed on the top of the reactor body 10, the swing rod 9 passes through the center of the fixed plate 1201, the top of the fixed plate 1201 is provided with the strip-shaped slot 1202 in a ring-shaped array, and the strip-shaped slots 1202 are distributed in a cross shape, the inside of the strip-shaped slot 1202 is slidably provided with the counterweight 1203, and the second connecting rod 1204 is hingedly installed between the top of the counterweight 1203 and the bottom of the side of the sliding block 6.

[0073] Local working principle: when the reactor body 10 swings due to vibration, the swing rod 9 drives the slider 6 to change the relative angle with the reactor body 10, the slider 6 pulls or pushes the counterweight 1203 along the cross-shaped distribution of the strip-shaped groove 1202 through the second connecting rod 1204, and the sliding speed is positively correlated with the swing angular speed. When the reactor body 10 swings to the left, the second connecting rod 1204 on the right pushes the counterweight 1203 to slide to the right, and the second connecting rod 1204 on the left pulls the counterweight 1203 to slide to the left, so that the overall center of gravity deviates to the opposite direction of the swing, offsets the unstable torque caused by the deviation of the center of gravity, maintains the balance of the reactor body 10, reduces the risk of structural damage, the mass of a single counterweight 1203 is 5%-8% of the total mass of the reactor body 10, ensures that the deviation of the center of gravity is ≤5mm, and offsets more than 90% of the unstable torque of the center of gravity.

[0074] As shown in Figures 1-10 , the use method of the anti-seismic type insulation resin pouring type flat wave reactor provided by the embodiment is as follows:

[0075] Step 1: installation and fixation, stably install the base 1 on the preset installation base, ensure that the load plate 2 is horizontally placed, check the initial state of the first spring 301 and the damper 302 in the longitudinal damping mechanism 3, ensure that they are not jammed, deformed, and in the normal pre-tightening state;

[0076] Step 2: initial debugging, confirm that the sleeve 701, the piston 702, the second spring 703 and the first connecting rod 704 of the horizontal damping mechanism 7 are reliably connected, the slider 6 slides smoothly in the hollow cavity 501 of the top plate 5, the ball 8 rotates flexibly in the spherical groove 601 of the slider 6, the resistance block 1105 of the rotary resistance mechanism 11 is not in contact with the ball 8 in the initial state, and the counterweight 1203 of the center of gravity adjusting mechanism 12 is located at the middle position of the strip-shaped groove 1202;

[0077] Step 3: vertical vibration response, when vertical vibration is encountered, the load plate 2 moves up and down relative to the base 1, the first spring 301 at four corners buffers the vertical impact through compression or stretching, the damper 302 in the middle generates damping force to consume vibration energy, and cooperates to reduce the intensity of the vertical vibration transmitted to the reactor body 10;

[0078] Step 4: horizontal vibration response, when horizontal vibration occurs, the reactor body 10 drives the swing rod 9, the ball 8 and the slider 6 to move along the horizontal direction, the slider 6 pushes the first connecting rod 704, so that the piston 702 slides in the sleeve 701, and the second spring 703 deforms due to the movement of the piston 702, and buffers the horizontal impact force through elastic force. At the same time, a plurality of horizontal damping mechanisms 7 cooperate to absorb vibration energy at different angles in the horizontal direction;

[0079] Step 5: swing and gravity adjustment, when the reactor body 10 swings due to vibration, the ball 8 rotates in the spherical groove 601, moving the column 1102 and the collar 1103, the collar 1103 pulls the resistance block 1105 along the sliding groove 1104 through the pull rope 1107, the third spring 1106 on the swing side is pulled through the pull rope 1107, and the opposite side of the third spring 1106 is released, so that the resistance block 1105 is in contact with the surface of the ball 8, increasing the resistance of the ball 8 to reduce the swing amplitude, at the same time, the swing lever 9 swings to drive the second connecting rod 1204, so that the counterweight 1203 slides along the strip-shaped groove 1202, dynamically adjusting the gravity center position of the reactor body 10, offsetting the instability caused by the gravity center deviation, in addition, the non-contact damping generated by the eddy current effect of the permanent magnet 13 and the eddy current plate 14 at the bottom of the reactor body 10 is used to weaken the vibration transmission and reduce the shaking amplitude;

[0080] Step 6: reset and check, after the vibration ends, the first spring 301, the second spring 703 and the third spring 1106 reset, driving the sliding block 6, the piston 702, the resistance block 1105 and the counterweight 1203 back to the initial position, checking whether there is wear, deformation or loose connection of each mechanism component, ensuring that the equipment is in normal standby state.
