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 easily leads to the gravity center deviation of the smoothing reactor, and causes problems such as bending of the insulation support and fracture of the winding lead. In addition, the spring is prone to 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 requirements in a high-intensity seismic area.

A horizontal shock-absorbing mechanism 7 is provided between the outer side of the slider 6 and the inner side of the top plate 5. When encountering horizontal vibration, the slider 6 drives the horizontal shock-absorbing mechanism 7 to deform and buffer. The bottom end of the sliding block 6 is provided with a spherical groove 601, a ball 8 is rotatably installed in the spherical groove 601, the bottom of the ball 8 is vertically fixed with a swing rod 9, the bottom end of the swing rod 9 is fixed with an electric reactor body 10, and the swing rod 9 is located at the center position of the top of the electric reactor body 10, and the winding outside of the electric reactor body 10 is mixed with an epoxy resin (model E-51) and a curing agent (methyl tetrahydrophthalic anhydride) at a mass ratio of 100:30, and 5%-10% of silicon powder (particle size 5-10 μm) is added to enhance the thermal conductivity.

The inside of the sliding block 6 is provided with a rotation resistance mechanism 11, which is used to reduce the amplitude of the swing of the ball 8, when torsion or swing occurs, the rotation resistance mechanism 11 increases the rotation resistance of the ball 8 to reduce the swing amplitude. The bottom end of the sliding block 6 and the electric reactor body 10 are provided with a gravity center adjusting mechanism 12, which is used to dynamically adjust the gravity center of the electric reactor body 10, when torsion or swing occurs, the gravity center adjusting mechanism 12 dynamically adjusts the gravity center of the electric reactor body 10 to maintain stability.

[0021] In this embodiment, the longitudinal damping mechanism 3 includes 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 position of the base 1 and the carrier plate 2.

[0022] 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, so as to convert the mechanical energy of vibration into heat energy and consume it, avoid the first springs 301 from generating continuous vibration due to resonance, and cooperatively reduce the transmission strength of the vertical vibration to the electric reactor body 10.

[0023] In the embodiment, the inner part of the top plate 5 is provided with a hollow cavity 501, a through port 502 is provided at the middle position of the bottom end of the hollow cavity 501 and is communicated with the bottom part of the top plate 5, and the cross-sectional shape of the sliding block 6 is T-shaped, the top end of the sliding block 6 is slidingly arranged in the hollow cavity 501, and the bottom end of the sliding block 6 passes out of the through port 502.

[0024] Local working principle: the hollow cavity 501 in the inner part of the top plate 5 provides horizontal sliding space for the sliding block 6, the through port 502 at the bottom end allows the bottom end of the sliding block 6 to pass out and be connected to the reactor body 10, the sliding block 6 is T-shaped, the top end is embedded in the hollow cavity 501, and the bottom end extends to the lower part of the top plate 5 through the through port 502, which not only limits the vertical displacement of the sliding block 6 but also ensures that the sliding block 6 can freely move along with the horizontal vibration, and meanwhile, the through port 502 plays a guiding role in the horizontal sliding of the sliding block 6, avoiding the deviation of the sliding block 6 from the preset track and ensuring that the horizontal damping mechanism 7 can stably respond to the vibration in the horizontal direction.

[0025] In the embodiment, the horizontal damping mechanism 7 includes 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 in the inner part of the sleeve 701, the second spring 703 is arranged between the two sides of the piston 702 and the end part of the sleeve 701, the first connecting rod 704 is fixed to the 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 sliding block 6.

[0026] Local working principle: when the equipment 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, so that the piston 702 slides in the sleeve 701, and when the piston 702 slides, the second spring 703 on the two sides of the piston 702 generates elastic force due to extrusion or stretching, so as to buffer the impact energy in the horizontal direction through elastic deformation, and 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 realize the buffering of vibration in multiple horizontal directions.

[0027] In the embodiment, the horizontal damping mechanism 7 is provided with six groups, and the included angles between adjacent horizontal damping mechanisms 7 are the same.

[0028] Local working principle: the six groups of mechanisms work together to cover 360° horizontal vibration in all directions, so as to ensure that the vibration from any horizontal angle can be effectively buffered through the corresponding horizontal damping mechanism 7 and improve the absorption efficiency of horizontal vibration.

[0029] In the embodiment, the rotating resistance mechanism 11 comprises sliding grooves 1104, resistance blocks 1105, third springs 1106 and a release assembly, the sliding grooves 1104 are evenly arranged in an annular array on the inner side of the spherical groove 601, the interior of the sliding grooves 1104 is slidably provided with the resistance blocks 1105, the interior of the sliding grooves 1104 and the resistance blocks 1105 are provided with the third springs 1106, and the third springs 1106 are in a compressed state. The top of the spherical groove 601 is provided with the release assembly for releasing the elastic force of the third springs 1106.

[0030] The local working principle is as follows: in the initial state, the third springs 1106 are in a compressed state, but the resistance blocks 1105 are not in contact with the ball 8 by 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 on the corresponding resistance block 1105, the compressed third spring 1106 pushes the resistance block 1105 to move along the sliding groove 1104 to the ball 8, so that the resistance block 1105 is in contact with the surface of the ball 8 and generates a friction force, which increases the rotating resistance of the ball 8, thereby reducing the swing amplitude of the reactor body 10 and avoiding excessive deviation.

[0031] In the embodiment, the release assembly comprises 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 interior 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 ropes 1107, the pull ropes 1107 are respectively fixed at the ends of the resistance blocks 1105, and the pull ropes 1107 slide in the interior of the sliding block 6.

[0032] The local working principle is as follows: when the ball 8 rotates with vibration, the stand 1102 fixed at the top of the ball 8 rotates synchronously and deviates in the movable groove 1101. The sleeve ring 1103 at the top end of the stand 1102 moves synchronously. The sleeve ring 1103 is connected with each resistance block 1105 through the pull rope 1107. When the ball 8 swings in a direction, the sleeve ring 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. 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 rotation of the ball 8 is hindered by the friction force. The dynamic resistance adjustment of "accumulating force on the swing side and applying resistance on the opposite side" is realized, and the swing amplitude is accurately reduced.

[0033] In the 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.

[0034] 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 is in contact with the surface of the ball 8, the rubber pad increases the contact area with the ball 8 by deformation, enhances the friction to increase the rotation resistance, and the anti-skid pattern at the bottom of the rubber pad further increases the surface roughness to avoid relative sliding between the resistance block 1105 and the ball 8, ensuring stable friction effect. At the same time, the elasticity of the rubber can buffer the instantaneous impact force during contact, avoid wear of the resistance block 1105 and the ball 8 due to rigid contact, and prolong the service life of the components.

[0035] In the embodiment, the gravity center adjusting mechanism 12 includes a fixed plate 1201, a strip-shaped groove 1202, a counterweight block 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 a plurality of strip-shaped grooves 1202 in a ring array, the strip-shaped grooves 1202 are distributed in a cross shape, the counterweight blocks 1203 are slidably arranged in the strip-shaped grooves 1202, and the second connecting rods 1204 are hingedly installed between the top of each counterweight block 1203 and the bottom of the side of the sliding block 6.

[0036] Local working principle: when the swing angle of the reactor body 10 due to vibration is greater than or equal to 5°, the swing rod 9 drives the sliding block 6 to change the relative angle with the reactor body 10, the sliding block 6 pulls or pushes the counterweight block 1203 to slide along the strip-shaped grooves 1202 distributed in a cross shape through the second connecting rod 1204, and the sliding speed is positively correlated with the swing angle speed. When the reactor body 10 swings to the left, the second connecting rod 1204 on the right pushes the counterweight block 1203 to slide to the right, and the second connecting rod 1204 on the left pulls the counterweight block 1203 to slide to the left, so that the overall gravity center deviates to the opposite direction of the swing, offsets the unstable torque caused by the deviation of the gravity center, maintains the balance of the reactor body 10, reduces the risk of structural damage, the mass of each counterweight block 1203 is 5%-8% of the total mass of the reactor body 10, and the deviation of the gravity center is less than or equal to 5 mm, so that more than 90% of the unstable torque of the gravity center is offset.

[0037] As shown in Figures 1-10 , the use method of the anti-seismic insulating resin pouring type flat wave reactor provided by the embodiment is as follows: Step 1: installation and fixation, stably installing the base 1 on a pre-installed installation base, ensuring that the carrier plate 2 is horizontally placed, checking the initial state of the first spring 301 and the damper 302 in the longitudinal damping mechanism 3, ensuring that they are not jammed, deformed, and in a normal pre-tightening state; Step 2: Initial debugging, confirm that the sleeve 701, piston 702, second spring 703 and first connecting rod 704 of the horizontal damping mechanism 7 are connected reliably, 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 rotation resistance mechanism 11 is not in contact with the ball 8 in the initial state, and the counterweight block 1203 of the gravity center adjusting mechanism 12 is located at the middle position of the strip-shaped groove 1202; Step 3: Vertical vibration response, when vertical vibration occurs, the carrier plate 2 moves up and down relative to the base 1, the first spring 301 at the four corners buffers the vertical impact by compression or stretching, and the damper 302 in the middle generates damping force to consume vibration energy, thereby reducing the strength of the vertical vibration transmitted to the reactor body 10; 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 in the horizontal direction, the slider 6 pushes the first connecting rod 704, the piston 702 slides in the sleeve 701, the second spring 703 deforms due to the movement of the piston 702, and buffers the horizontal impact force through elastic force, and multiple sets of horizontal damping mechanisms 7 cooperate to absorb vibration energy in different angles in all directions; Step 5: Swing and gravity center adjustment, when the reactor body 10 swings due to vibration, the ball 8 rotates in the spherical groove 601, driving the vertical column 1102 and the sleeve ring 1103 to move, the sleeve ring 1103 pulls the resistance block 1105 to slide along the sliding groove 1104 through the pull rope 1107, the third spring 1106 on the swing side is pulled by the pull rope 1107 to be stressed, while the elastic force of the third spring 1106 on the opposite side is released, so that the resistance block 1105 is in contact with the surface of the ball 8, increasing the rotation resistance of the ball 8 to reduce the swing amplitude, at the same time, the swing of the swing rod 9 drives the second connecting rod 1204, making the counterweight block 1203 slide along the strip-shaped groove 1202, dynamically adjusting the gravity center position of the reactor body 10 to offset 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 at the bottom of the reactor body 10 and the eddy current plate 14 weakens the vibration transmission and reduces the shaking amplitude; Step 6: Reset and check, after the vibration ends, the first spring 301, the second spring 703 and the third spring 1106 are reset, driving the slider 6, the piston 702, the resistance block 1105 and the counterweight block 1203 to return to the initial position, checking whether there is wear, deformation or loose connection of the components of each mechanism to ensure that the equipment is in normal standby state.

10. A method for using a seismic-resistant insulating resin cast smoothing reactor, based on the seismic-resistant insulating resin cast smoothing reactor according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: Install and fix. Firmly install the base (1) on the preset installation foundation, ensure that the carrier plate (2) is placed horizontally, and check the initial state of the first spring (301) and the damper (302) in the longitudinal shock absorbing mechanism (3) to ensure that they are not stuck or deformed and are in a normal pre-tightened state; Step 2: Initial debugging, confirm that the sleeve (701), piston (702), second spring (703) and first connecting rod (704) of the horizontal shock absorbing 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 rotation resistance mechanism (11) and the ball (8) are not in contact in the initial state, and the counterweight block (1203) of the center of gravity adjustment mechanism (12) is located in the middle of the strip groove (1202); Step 3: Response to vertical vibration. When encountering vertical vibration, the carrier plate (2) moves up and down relative to the base (1). The first springs (301) at the four corners buffer the vertical impact by compression or tension, and the damper (302) in the middle generates a damping force to consume vibration energy, thereby synergistically reducing the intensity of the vertical vibration transmitted to the reactor body (10). Step 4: Response to horizontal vibration. When horizontal vibration occurs, the reactor body (10) drives the rocker (9), the ball (8) and the slider (6) to move in the horizontal direction. The slider (6) pushes the first connecting rod (704) to make the piston (702) slide in the sleeve (701). The second spring (703) is deformed due to the movement of the piston (702). The elastic force buffers the horizontal impact force. At the same time, multiple groups of horizontal shock absorbing mechanisms (7) cooperate to absorb the vibration energy at different angles in the horizontal direction in all directions. Step 5: Swing and adjust the center of gravity. When the reactor body (10) swings due to vibration, the ball (8) rotates in the spherical groove (601), driving the column (1102) and the ring (1103) to move. The ring (1103) pulls the resistance block (1105) to slide along the slide groove (1104) through the pull rope (1107). The third spring (1106) on the swing side is pulled and compressed by the pull rope (1107), while the elastic force of the third spring (1106) on the opposite side is released, so that the resistance block (1105) ) contacts the surface of the ball (8), increases the rotational resistance of the ball (8) to reduce the swing amplitude, and at the same time, the swing rod (9) swings to drive the second connecting rod (1204), so that the counterweight block (1203) slides along the strip groove (1202), dynamically adjusts the center of gravity position of the reactor body (10), and offsets the unstable effect caused by the center of gravity offset. In addition, the permanent magnet (13) at the bottom of the reactor body (10) and the eddy current plate (14) use the eddy current effect to generate non-contact damping to weaken vibration transmission and reduce the vibration amplitude; Step 6: Reset and check. After the vibration ends, the first spring (301), the second spring (703), and the third spring (1106) are reset, driving the slider (6), the piston (702), the resistance block (1105), and the counterweight block (1203) back to their initial positions. Check whether the various parts of the mechanism are worn, deformed, or loosely connected to ensure that the equipment is in a normal standby state.
