Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to an oil-immersed transformer with a vibration damping and noise reduction structure. Background Technology

[0002] Oil-immersed transformers are power transformation devices that use mineral insulating oil as the internal insulation and heat dissipation medium. They rely on the principle of electromagnetic induction to realize the conversion of voltage and current into electrical energy. The core and winding core components are completely immersed in transformer oil. During operation, the heat generated by the winding and core is transferred to the heat dissipation structure of the tank through oil convection and dissipated outward. At the same time, the oil isolates the live parts from the metal shell to ensure insulation safety.

[0003] During operation, the magnetostriction of the iron core and the electromagnetic force of the windings of an oil-immersed transformer will continuously excite vibration. The vibration is transmitted through the solid structure and the resonance of the tank is converted into continuous noise. This noise will cause noise pollution to the surrounding living environment. Long-term vibration will also continuously pull on the pipeline, bushing and internal winding structure, causing equipment loss problems such as loosening of components, leakage and insulation damage. Therefore, it is necessary to set up a vibration reduction and noise reduction structure to weaken the vibration noise, while taking into account the compliance of the surrounding sound environment and the long-term operational reliability of the equipment.

[0004] In existing technology, oil-immersed transformers generate continuous vibration and radiate noise during operation, which can easily cause noise pollution in the surrounding environment. At the same time, long-term transmission of vibration can exacerbate the loosening and leakage of various connecting parts. In addition to rain and sun protection, a shielding shell is added to protect the transformer, but this can easily lead to an increase in the internal temperature of the equipment. Therefore, a new design has been developed to address these issues. Summary of the Invention

[0007] The transformer base also includes a circular plate, which is disposed outside the guide rod. The inner side of the circular plate is slidably connected to the guide rod. A connecting rod and a receiving block are fixedly connected to the outer side of the circular plate away from the sliding block. The receiving block has a cylindrical shell structure. A groove is formed inside the receiving block at a position corresponding to the connecting rod. The groove is adapted to the insertion and removal of the connecting rod.

[0008] The output end of the electric push rod is fixedly connected to a docking block, and the inner side of the docking block is fitted with a docking end. The other side of the docking end is fixedly connected to the inner wall of the frame.

[0009] The protective mechanism includes a first housing and a second housing. Both sides of the first housing and the second housing are fixedly connected to external plates. A screw is fixedly connected to one side of the external plate of the first housing. The screw passes through the external plate of the second housing, and a fixing member is threaded to the outside of the screw.

[0010] Both sides of the inner walls of the first housing and the second housing are fixedly connected with snap-fit ​​plates, which are slidably adapted to the guide block. The outer side of the first housing and the second housing away from the transformer body is fixedly connected with a positioning mechanism.

[0011] The outer plate of the second housing has a slot on the plate surface, which is compatible with the fastener for insertion and removal, and the fastener is provided with a reinforcement mechanism on the outside.

[0012] A ventilation housing is fixedly connected to the outside of the second housing on the side away from the first housing. A fan is fixedly connected inside the ventilation housing, and a grating plate is fixedly connected to the outside of the ventilation housing near the fan.

[0013] The positioning mechanism includes a positioning housing, a second spring is provided inside the positioning housing, a positioning support rod is slidably connected inside the positioning housing, and a positioning plate is fixedly connected to the end of the positioning support rod away from the second spring.

[0014] The fixing component includes a fixed housing, the fixed housing has a housing groove inside, a sliding rod is slidably connected inside the housing groove, and a blocking block is fixedly connected to the outside of the sliding rod near the housing groove.

[0015] The reinforcement mechanism includes a reinforcement shell, a plastic strip is fixedly connected to the inner wall of the reinforcement shell near the fixed shell, and a toothed groove is opened on the outer side of the reinforcement shell away from the fixed shell.

[0016] This invention provides an oil-immersed transformer with a vibration-damping and noise-reducing structure. It has the following beneficial effects:

[0017] I. This oil-immersed transformer with a vibration damping and noise reduction structure features a sliding block at the bottom of the transformer base when the equipment experiences collisions or other incidents. The sliding block slides on a guide rod to relieve pressure and reduce surface pressure on components. As the sliding block slides on the guide rod, it compresses the first springs on both sides according to the sliding direction, thus acting as a shock absorber and buffer, absorbing horizontal vibrations. Appropriate displacement reduces equipment vibration and buffers impact loads. Simultaneously, lateral buffering compensates for any shortcomings in vibration damping, providing comprehensive suppression of multi-directional vibrations, reducing the equipment's own vibration, and achieving noise reduction through overall vibration damping. A baffle plate is located outside the transformer base near the top of the base housing. The baffle plate adheres to the top of the base housing and moves with the sliding block, providing a certain degree of shielding to the top of the base housing, reducing the entry of external impurities, preventing interference with the operation of internal components, and thus extending the service life of the components.

[0018] II. In this oil-immersed transformer with a vibration damping and noise reduction structure, a first spring supports a circular plate, causing the circular plate to fit against both sides of a sliding block. When the sliding block moves, it causes the circular plate to compress and contract the first spring. Secondly, a connecting rod is provided on the outer side of the circular plate. When the circular plate slides with the connecting rod, the connecting rod is inserted and matched with the groove on the surface of the receiving block. The receiving block supports the connecting rod, thereby achieving the effect of limiting the component's sliding range, preventing excessive sliding, preventing damage to the spring, and extending the service life of the component. At the same time, the component support provides a certain degree of protection for the equipment, preventing component collision damage.

[0019] III. This oil-immersed transformer with a vibration damping and noise reduction structure has a first shell and a second shell that are fitted together with the transformer body as the axis. Both the first and second shells have external plates on both sides. The external plates are fitted together with the first and second shells. However, the external plate of the first shell is equipped with a screw that is aligned with the hole of the external plate of the second shell. When the first and second shells are installed in alignment, the screw plays a positioning and alignment role. Then, the fasteners are threaded onto the screws to lock the two shells together, preventing the components from moving. The two shells also shield the transformer body, thereby blocking the air noise radiated outward from the equipment, protecting the equipment, reducing external rainwater erosion, reducing external impacts, and achieving the functions of vibration damping and noise reduction.

[0020] IV. The oil-immersed transformer with vibration damping and noise reduction structure has guide blocks on both sides of the top of the transformer base. The guide blocks guide the transformer body into the transformer base, and the snap-fit ​​plate slides and engages with the guide blocks. The snap-fit ​​plate is set on both sides of the inner wall of the first housing and the second housing. When the first housing and the second housing are installed and connected, the snap-fit ​​plate and the guide block need to be connected and slid together to improve the stability of the housing connection and prevent the housing from shifting. At the same time, the guide block is on top and the snap-fit ​​plate is on the bottom to prevent the housing from falling off and improve the stability of the housing installation.

[0021] 5. In this oil-immersed transformer with a vibration damping and noise reduction structure, the fixing component, while tightening the components during the rotation of the screw, fits against the slot on the plate surface to prevent the fixing component from loosening. The reinforcement mechanism is threadedly connected to the screw to support and reinforce the fixing component, thereby achieving a double tightening effect and further strengthening the connection effect of the components.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] First embodiment, such as Figures 1 to 5As shown, the present invention provides a technical solution: an oil-immersed transformer with a vibration damping and noise reduction structure, including a transformer base 1, a base groove 2 centrally located at the top of the transformer base 1, a transformer body 7 disposed inside the base groove 2, guide blocks 8 fixedly connected to both sides of the top of the transformer base 1 near the transformer body 7, a transformer base 5 slidably connected to the bottom of the transformer base 1, a protective mechanism 6 disposed at the top of the transformer base 1, a frame-shaped frame 3 disposed at the bottom of the transformer body 7, the top of the frame-shaped frame 3 fixedly connected to the bottom of the transformer body 7, an electric push rod 9, the outer side of the electric push rod 9 fixedly connected to the bottom of the inner wall of the base groove 2, and the output end of the electric push rod 9 pressing and fitting the frame-shaped frame 3; the transformer body 7 is pushed into the base groove 2 of the transformer base 1 along the guide blocks 8, and the transformer body 7 is engaged. The base groove 2 is located inside the base to fit the bottom of the equipment, thus achieving pre-positioning and preventing the equipment from moving. The transformer base 5 is located at the bottom of the transformer base 1 to support the transformer base 1, increase the height of the components, reduce moisture ingress, and protect the internal electronic components of the equipment, ensuring continuous operation. The protective mechanism 6 is located at the top of the transformer base 1 to shield and protect the transformer body 7, thus providing a certain degree of waterproofing and impact protection, improving the safety of the equipment during operation. The bottom of the transformer body 7 is provided with a frame-shaped frame 3. After the frame-shaped frame 3 is placed inside the base groove 2, it is squeezed from both sides by the electric push rod 9 to squeeze and clamp the frame-shaped frame 3, thereby further reinforcing the stability of the equipment, preventing the equipment from shifting, and improving the subsequent stability of the equipment.

[0033] The output end of the electric push rod 9 is fixedly connected to a docking block 10. A docking end 4 is pluggable and insertable inside the docking block 10. The other side of the docking end 4 is fixedly connected to the inner wall of the frame 3. The docking block 10 is located at the output end of the electric push rod 9. Furthermore, a groove the size of the docking end 4 is opened inside the docking block 10. The docking end 4 is located on the inner wall of the frame 3 at a position corresponding to the docking block 10. When the electric push rod 9 controls the docking block 10 to press and fit against the docking end 4, it presses and clamps the frame 3 to maintain the stability of the transformer body 7. On the other hand, through the interlocking of the components, it further restricts the range of motion of the equipment and strengthens the fixing effect of the equipment. Before the clamping is loosened, it prevents the equipment from being moved by means of handling.

[0034] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 4 to 5 As shown, the transformer base 5 includes a base housing 501. A housing groove 502 is provided inside the base housing 501. A guide rod 503 is fixedly connected inside the housing groove 502. A sliding block 504 is slidably connected outside the guide rod 503. The top of the sliding block 504 is fixedly connected to the bottom of the transformer base 1.

[0035] And a first spring 506 is provided at both ends of the guide rod 503. The first spring 506 is sleeved on the guide rod 503. A baffle plate 505 is fixedly connected to both sides of the transformer base 1. When the equipment is involved in a collision, a sliding block 504 is installed at the bottom of the transformer base 1. The sliding block 504 slides on the guide rod 503 to relieve pressure and reduce the surface pressure of the components. When the sliding block 504 slides on the guide rod 503, it compresses and contracts the first springs 506 on both sides according to the sliding direction, thereby playing a role in shock absorption and absorbing the horizontal vibration. By appropriately displacing, it reduces equipment vibration and buffers impact loads. At the same time, the lateral buffering compensates for the lack of shock absorption, playing a role in suppressing multi-directional vibration in all directions, reducing the vibration of the equipment itself, and reducing noise through overall shock absorption. The baffle plate 505 is set on the outside of the transformer base 1 near the top of the base housing 501. The baffle plate 505 fits against the top of the base housing 501 and moves with the sliding block 504 to provide a certain degree of shielding on the top of the base housing 501, reducing the entry of external impurities, avoiding affecting the operation of internal components, and thus extending the service life of the components.

[0036] The transformer base 5 also includes a circular plate 507, which is disposed outside the guide rod 503. The inner side of the circular plate 507 is slidably connected to the guide rod 503. A connecting rod 508 and a receiving block 509 are fixedly connected to the outer side of the circular plate 507 away from the sliding block 504. The receiving block 509 has a cylindrical shell structure. A block groove 510 is provided inside the receiving block 509 at a position corresponding to the connecting rod 508. The block groove 510 is plug-in and pluggable with the connecting rod 508. The first spring 506 supports the circular plate 507, causing the circular plate 507 to fit against both sides of the sliding block 504. When the sliding block 504 moves, it causes the circular plate 507 to compress and contract the first spring 506. Next, a connecting rod 508 is provided on the outer side of the circular plate 507. When the circular plate 507 drives the connecting rod 508 to slide, the connecting rod 508 is inserted and matched with the groove 510 on the surface of the receiving block 509. The receiving block 509 supports the connecting rod 508, thereby achieving the effect of component positioning, limiting the sliding range of the component, avoiding excessive sliding of the component, preventing damage to the spring, and thus extending the service life of the component. At the same time, the component support provides a certain degree of protection for the equipment, preventing component collision damage.

[0037] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 6 to 8As shown, the protective mechanism 6 includes a first housing 601 and a second housing 602. Both sides of the first housing 601 and the second housing 602 are fixedly connected to an outer plate 604. A screw 603 is fixedly connected to one side of the outer plate 604 of the first housing 601. The screw 603 passes through the outer plate 604 of the second housing 602. A fastener 606 is threadedly connected to the outside of the screw 603. The first housing 601 and the second housing 602 are mated together with the transformer body 7 as the axis. Both the first housing 601 and the second housing 602 are provided with external plates 604 on both sides. The external plates 604 are mated together with the first housing 601 and the second housing 602. However, the external plates 604 of the first housing 601 are provided with screws 603, which are aligned with the holes of the external plates 604 of the second housing 602. When the first housing 601 and the second housing 602 are aligned and installed, the screws 603 play a positioning and alignment role. Then, the fasteners 606 are threadedly connected to the screws 603 to lock the two housings, prevent the components from moving, and shield the transformer body 7 with the two housings, thereby blocking the air noise radiated outward from the equipment, protecting the equipment, reducing external rainwater erosion, reducing external impact, and also achieving the functions of shock absorption and noise reduction.

[0038] Both sides of the inner walls of the first housing 601 and the second housing 602 are fixedly connected with snap-fit ​​plates 609. The snap-fit ​​plates 609 are slidably adapted to the guide blocks 8. The outer sides of the first housing 601 and the second housing 602 away from the transformer body 7 are fixedly connected with positioning mechanisms 608. Guide blocks 8 are provided on both sides of the top of the transformer base 1. Based on the guide blocks 8 guiding the transformer body 7 into the transformer base 1, the snap-fit ​​plates 609 slide and engage with the guide blocks 8. The snap-fit ​​plates 609 are located on both sides of the inner walls of the first housing 601 and the second housing 602. When the first housing 601 and the second housing 602 are installed and connected, the snap-fit ​​plates 609 and the guide blocks 8 need to be connected and slidably fitted to improve the stability of the housing connection and prevent the housing from shifting. At the same time, the guide blocks 8 are on top and the snap-fit ​​plates 609 are on the bottom to prevent the housing from falling off and improve the stability of the housing installation.

[0039] The outer plate 604 of the second housing 602 has a slot 605, which is pluggable and adaptable to the fastener 606. A reinforcing mechanism 607 is provided on the outside of the fastener 606. During the rotation of the screw 603, the fastener 606 is tightened and then pressed against the slot 605 to prevent it from loosening. The reinforcing mechanism 607 is threaded onto the screw 603 to support and reinforce the fastener 606, thereby achieving a double tightening effect and further strengthening the connection of the components.

[0040] A ventilation housing 610 is fixedly connected to the exterior of the second housing 602, away from the side of the first housing 601. A fan 611 is fixedly connected inside the ventilation housing 610, and a grille 612 is fixedly connected to the exterior of the ventilation housing 610 near the fan 611. The ventilation housing 610 is tangentially connected to the second housing 602. The ventilation slots inside the ventilation housing 610 are designed with a downward slope to reduce the ingress of external rainwater and prevent corrosion of the equipment's interior. The fan 611 generates airflow to exhaust the airflow from inside the housing, thereby achieving ventilation and heat dissipation, reducing the internal temperature of the equipment, preventing excessive internal temperature from affecting equipment operation, and preventing external impurities from entering and affecting equipment operation.

[0041] The positioning mechanism 608 includes a positioning housing 6081, inside which a second spring 6082 is installed. A positioning support rod 6083 is slidably connected inside the positioning housing 6081, and a positioning plate 6084 is fixedly connected to the outer end of the positioning support rod 6083 away from the second spring 6082. The positioning plate 6084 is attached to the bottom of the transformer body 7. Positioning mechanisms 608 are provided on the lower inner walls of both the first housing 601 and the second housing 602. When the first housing 601 and the second housing 602 are relatively attached, the positioning plate 6084 is attached to the bottom of the transformer body 7. As the docking pressure increases, the positioning plate 6084 drives the positioning support rod 6083 to compress and contract the second spring 6082, thereby playing a role in shock absorption and buffering. At the same time, the second spring 6082 compresses and clamps the positioning support rod 6083, thereby achieving the function of clamping and fixing the equipment, further improving the stability of the equipment, absorbing the vibration generated during equipment operation, reducing the transmission of equipment vibration, and improving the stability of equipment operation.

[0042] The fastener 606 includes a fixed housing 6061, with a housing groove 6062 inside the fixed housing 6061. A sliding rod 6063 is slidably connected inside the housing groove 6062, and a stop block 6064 is fixedly connected to the outside of the sliding rod 6063 near the housing groove 6062. The fixed housing 6061 is in the form of a nut, which rotates on the screw 603 to tighten and fix the housing, thereby achieving the connection effect of the component. When the fixed housing 6061 is attached to the outer plate 604, it pushes the sliding rod 6063 from one end of the fixed housing 6061 into the slot 605 on the plate surface, thereby strengthening the stability of the fixed housing 6061, preventing the fixed housing 6061 from rotating and loosening, and extending the working efficiency of the component. Secondly, the stop block 6064 is located in the middle of the sliding rod 6063 and slides inside the housing groove 6062 to prevent the sliding rod 6063 from derailing and maintain the connection effect of the component.

[0043] The reinforcement mechanism 607 includes a reinforcement housing 6071. A plastic strip 6072 is fixedly connected to the inner wall of the reinforcement housing 6071 near the fixed housing 6061. A toothed groove 6073 is formed on the outer side of the reinforcement housing 6071 away from the fixed housing 6061. By rotating the reinforcement housing 6071, it adheres to the fixing member 606 from one end of the screw 603. The toothed groove 6073 on one side of the reinforcement housing 6071 increases the surface friction of the component, facilitating the rotation of the component. Furthermore, the plastic strip 6072 on the inner wall of the reinforcement housing 6071 adheres to the fixed housing 6061 with continuous rotation. As the component rotates, the plastic strip 6072 rotates and adheres to the surface of the fixed housing 6061, thereby increasing the surface friction of the component, providing an anti-slip effect, and providing a pulling effect, further reinforcing the stability of the component.

[0044] In use, the transformer base 1 is used to support the transformer body 7. The bottom of the transformer body 7 is provided with a frame-shaped frame 3. The transformer base 1 has a base groove 2 in the middle. An electric push rod 9 is provided at the center of the bottom of the inner wall of the base groove 2. Guide blocks 8 are provided on the top of the transformer base 1 near the two sides of the base groove 2. The distance between the two guide blocks 8 matches the size of the transformer body 7.

[0045] Align the transformer body 7 with the guide blocks 8, push the transformer body 7 into the guide blocks 8, so that the frame frame 3 is embedded in the inner wall of the base groove 2, the outer side of the frame frame 3 fits against the inner wall of the base groove 2, and the two sides of the inner wall of the frame frame 3 are provided with docking ends 4. The docking block 10 is controlled by the electric push rod 9 to fit against the docking end 4. The docking block 10 and the docking end 4 are fitted together. The electric push rod 9 cooperates with the docking block 10 and the docking end 4 to fit together, thereby achieving the function of clamping and fixing the component. On the basis of squeezing and fixing, it plays the role of limiting the movement of the component and preventing the transformer body 7 from falling off.

[0046] The protective mechanism 6 is internally provided with a first housing 601 and a second housing 602. The inner walls of the first housing 601 and the second housing 602 are provided with snap-fit ​​plates 609 on both sides corresponding to the guide block 8. When the first housing 601 and the second housing 602 are connected at the top of the transformer base 1, the first housing 601 and the second housing 602 slide along the guide block 8 through the snap-fit ​​plates 609, so that the snap-fit ​​plates 609 are attached to the inner side of the guide block 8, thereby guiding the components to fit together and preventing the housing from falling upward.

[0047] When the first housing 601 and the second housing 602 are connected, the screw 603 of the first housing 601 is inserted into the second housing 602. Then, by threading the fastener 606 onto the screw 603, the two external plates 604 drive the first housing 601 and the second housing 602 to close. This serves to block the air noise radiated outward from the equipment, protect the equipment, reduce external rainwater erosion, reduce external impacts, and also reduce vibration and noise. Secondly, a reinforcing mechanism 607 is added to the screw 603. The reinforcing mechanism 607 wraps around the fastener 606 from one side, thereby strengthening the stability of the fastener 606, improving the fixing effect of the components, preventing some components from falling off, and thus ensuring the operation of the equipment.

[0048] When the first housing 601 and the second housing 602 are docked, the positioning mechanism 608 is pressed from the bottom of both sides of the transformer body 7. By pressing, pressure is applied on the basis of the original fixation, thereby further improving the stability of the components. In addition, the second housing 602 is equipped with a fan 611 to reduce the internal temperature of the housing and prevent the electronic components of the equipment from malfunctioning. It works in coordination with the housing to maintain ventilation and heat dissipation while protecting the transformer body 7.

[0049] The bottom of the transformer base 1 is slidably fitted with the transformer base 5, and the transformer base 5 supports the transformer base 1. When the equipment vibrates during operation or is subjected to external impact, the transformer base 1 drives the transformer body 7 to slide appropriately on the transformer base 5, thereby playing a role in shock absorption and absorbing the horizontal vibration generated. By appropriately displacing, the equipment vibration is reduced and the impact load is buffered. At the same time, the lateral buffering makes up for the lack of shock absorption, thereby suppressing multi-directional vibration in all directions, reducing the vibration of the equipment itself, and reducing noise through overall shock absorption.

[0050] Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
