Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, specifically a low-noise dry-type transformer. Background Technology

[0002] In power systems, dry-type transformers are an important type of electrical equipment, widely used in various power distribution scenarios, undertaking the key tasks of voltage transformation and power transmission. Among them, low-noise dry-type transformers have been widely used in places with strict environmental noise requirements, such as data centers, hospitals, and precision manufacturing workshops, due to their advantages of low operating noise and environmental friendliness.

[0003] The stable operation of dry-type transformers is highly dependent on the stability and flatness of their installation foundation. As the supporting structure of the transformer, the installation foundation must be kept absolutely level during the installation process, and the error is usually required to be no more than ±2mm. If the foundation is tilted, it will cause the overall center of gravity of the transformer to shift, causing the core components such as the iron core and windings inside the transformer to be subjected to uneven stress. Under long-term operation, this uneven stress will accelerate the aging of the insulation material, reduce the insulation performance of the transformer, and increase the risk of short-circuit faults.

[0004] my country has a vast territory and complex and diverse geological conditions. Some areas are located in earthquake-prone zones. In these areas, earthquakes occur frequently and with varying intensities, which places extremely high demands on the seismic resistance of power equipment. As a key piece of equipment in the power system, dry-type transformers, if damaged in an earthquake, may cause large-scale power outages, seriously affecting social production and people's lives.

[0005] However, current base designs mainly focus on improving the transformer's horizontal seismic resistance, but fail to fully consider the important impact of levelness on seismic resistance. As a result, in complex geological conditions, especially in earthquake-prone areas, dry-type transformers still face a significant risk of damage when facing earthquake disasters.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

[0007] The purpose of this invention is to provide a low-noise dry-type transformer to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides a low-noise dry-type transformer, including a balancing mechanism. The balancing mechanism includes a right-side fixing block, a connecting rod, a rear-side fixing block, a left-side fixing block, a front-side fixing block, and an adjusting component. The ends of the right-side fixing block, the rear-side fixing block, the left-side fixing block, and the front-side fixing block slide against each other. The length ratio of the right-side fixing block, the left-side fixing block, the rear-side fixing block, and the front-side fixing block is 3:4. The adjustment assembly includes a universal joint, a sleeve shaft is rotatably mounted on the bottom of the universal joint, short rods are fixedly mounted on both outer walls of the sleeve shaft, a ball shaft is rotatably mounted on the inner wall of the sleeve shaft, long rods are fixedly mounted on both outer walls of the ball shaft, and gears are fixedly mounted at the ends of the long rods and short rods. The outer walls of the four gears are correspondingly meshed with the inner walls of the right fixed block, the rear fixed block, the left fixed block, and the front fixed block. The inner wall of the right fixed block is provided with an adjustment groove, and a gear column is slidably installed on the inner wall of the adjustment groove. A base plate is fixedly installed at the bottom of the gear column, and the side wall of the gear column is meshed with one of its gears.

[0009] Furthermore, the top of the adjusting component is fixedly connected to the connecting rod, and the top of the connecting rod extends 2 to 3 cm beyond the top of the right-side fixing block; The outer wall of the ball shaft has the same dimensions as the inner wall of the sleeve shaft, and the outer wall of the ball shaft is coated with lubricating oil.

[0010] Furthermore, the bottom of the base plate has threaded holes, which can be connected to the fastening surface by bolts.

[0011] Furthermore, the right-side fixing block has the same internal structure as the rear-side fixing block, the left-side fixing block, and the front-side fixing block. The right-side fixing block, the rear-side fixing block, the left-side fixing block, and the front-side fixing block are all solid stainless steel and their outer walls are all wrapped with rubber sleeves. The bottom of the base plate is provided with a rubber pad, and the bottom of the rubber pad has an integrally formed anti-slip texture.

[0012] Furthermore, a spring damper is fixedly connected to the top of the toothed column, and the top of the spring damper is fixedly connected to the top of the inner wall of the adjusting groove; The connecting rod is fixedly connected to a shock-absorbing bracket on its side wall, and a low-noise dry-type transformer is threadedly installed on the top of the shock-absorbing bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The transformer's own weight presses down, the connecting rod drives the adjusting component to move down, and the gear column and the base plate move down synchronously. When one side of the base plate contacts the mounting surface first, the rotation of the gear drives the gear column on the opposite side to continue to move down until all the base plates contact the mounting surface, so that the transformer reaches a balanced state. This ensures the overall stability of the transformer's center of gravity and avoids uneven stress on the internal core, windings and other core components due to uneven installation, thus ensuring the long-term stable operation of the transformer. When encountering complex geological conditions such as earthquakes, the anti-seismic support and the balancing mechanism work together. The adjustment components of the balancing mechanism can be flexibly adjusted, and together with the spring damper, they buffer the vibration energy, enabling the low-noise dry-type transformer to adapt to changes in ground vibration, always maintain balance, avoid damage, and reduce the risk of short-circuit faults.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4This utility model provides a technical solution: a low-noise dry-type transformer, including a balancing mechanism 2. The balancing mechanism 2 includes a right-side fixing block 201, a connecting rod 202, a rear-side fixing block 203, a left-side fixing block 204, a front-side fixing block 205, and an adjusting component 206. The ends of the right-side fixing block 201, rear-side fixing block 203, left-side fixing block 204, and front-side fixing block 205 slide relative to each other to form a rectangle, thus creating a stable frame structure for the balancing mechanism 2. Furthermore, the length ratio of the right-side fixing block 201, left-side fixing block 204 to the rear-side fixing block 203 and front-side fixing block 205 is 3:4, which helps... To achieve a more uniform force distribution during transformer installation, the adjustment assembly 206 includes a universal joint 2064. A sleeve shaft 2063 is rotatably mounted at the bottom of the universal joint 2064. A ball shaft 2065 rotatably mounted on the inner wall of the sleeve shaft 2063 further increases the adjustment flexibility. The ball shaft 2065 can rotate within the sleeve shaft 2063, cooperating with the universal joint 2064 to allow the long rod 2061 and short rod 2062 to drive their own gear 2066 to rotate in three-dimensional space, thereby achieving horizontal adjustment of the transformer in multiple directions (front, back, left, and right). Short rods 2062 are fixedly mounted on the outer walls of both sides of the sleeve shaft 2063. A ball shaft 2065 is rotatably mounted on the inner wall of the 063. Long rods 2061 are fixedly mounted on the outer walls of both sides of the ball shaft 2065. Gears 2066 are fixedly mounted at the ends of both the long rods 2061 and the short rods 2062. The outer walls of the four gears 2066 mesh correspondingly with the inner walls of the right-side fixed block 201, the rear fixed block 203, the left-side fixed block 204, and the front fixed block 205. An adjustment groove 2014 is provided on the inner wall of the right-side fixed block 201, providing sliding space for the gear column 2012, allowing it to move vertically up and down. When the transformer is depressurized, the gear column 2012 moves with the adjustment assembly. The downward movement of 206 causes the base plate 2011 to move downward as well. When the base plate 2011 contacts the mounting surface, the gear 2012 is fixed in the adjustment groove 2014. At this time, the gear 2066 meshing with it can no longer drive the gear 2012 downward. Instead, the force is transmitted to the gear 2012 in other directions through the rotation of the gear 2066, so that the gear 2012 on the opposite side can continue to move downward, thereby completing the horizontal adjustment process. The gear 2012 is slidably installed on the inner wall of the adjustment groove 2014. The base plate 2011 is fixedly installed on the bottom of the gear 2012. The side wall of the gear 2012 is meshed with one of its gears 2066.

[0018] It should be noted that: the two gears 2066 mesh with each other on one side of the tooth post 2012, which causes the tooth post 2012 on the opposite side to continue to move downward.

[0019] Please see Figure 4This utility model provides a technical solution: a low-noise dry-type transformer, including a spring damper 2013 fixedly connected to the top of the toothed column 2012. The elasticity of the spring damper 2013 can provide a flexible support for balance adjustment. When the adjustment component 206 drives the toothed column 2012 to move, the spring damper 2013 will deform accordingly according to the force. The top of the spring damper 2013 is fixedly connected to the top of the inner wall of the adjustment groove 2014, which can help the balance mechanism 2 to achieve horizontal adjustment more smoothly and avoid jamming or over-adjustment during the adjustment process.

[0020] Please see Figure 1 This utility model provides a technical solution: a low-noise dry-type transformer, including an adjustment component 206 with a connecting rod 202 fixedly installed on the top, the top of the connecting rod 202 extending 2 to 3 cm beyond the top of the right-side fixing block 201; a shock-absorbing bracket 3 is fixedly connected to the side wall of the connecting rod 202, the shock-absorbing bracket 3 playing a key isolation role, which can block the transmission path of vibration of the low-noise dry-type transformer 1 to the connecting rod 202 and other connected components. The low-noise dry-type transformer 1 is threadedly installed on the top of the shock-absorbing bracket 3, avoiding the spread of vibration within the system, reducing equipment wear, loose connections and other faults caused by vibration, and ensuring the stable operation of the entire system.

[0021] Please see Figure 2 This utility model provides a technical solution: a low-noise dry-type transformer, including a right-side fixing block 201 and a rear-side fixing block 203, a left-side fixing block 204 and a front-side fixing block 205 with the same internal structure, all of which are solid stainless steel. This material has high strength and good rigidity, and its structure can ensure that no obvious deformation occurs, providing stable and reliable support for the entire balancing mechanism 2. The outer wall of the ball shaft 2065 has the same size as the inner wall of the sleeve shaft 2063, and the outer wall of the ball shaft 2065 is coated with lubricating oil.

[0022] Please see Figure 1 This utility model provides a technical solution: a low-noise dry-type transformer, including a base plate 2011 with a threaded hole at the bottom, which is connected to a fastening surface by bolts. During the connection process, the bolt connection can generate a large preload force, thereby fixing the base plate 2011 to the fastening surface.

[0023] Working principle: When installing the low-noise dry-type transformer 1, the low-noise dry-type transformer 1 with the balancing mechanism 2 is placed on the mounting surface. As the weight of the low-noise dry-type transformer 1 presses down, the connecting rod 202 moves downward, driving the connected adjusting component 206 to move downward. This causes the gear 2012 inside the right fixing block 201, rear fixing block 203, left fixing block 204, and front fixing block 205 to move downward synchronously with the base plate 2011. Due to the unevenness of the mounting surface, during the downward movement of the base plate 2011, one side may contact the mounting surface first. When one side of the base plate 2011 contacts first, the gear 2012 on that side is fixed. Because it meshes with the gear 2066, the gear 2066 tilts to the other side with the center point of the adjusting component 206 as the axis, driving the gear 2012 on that side to move downward. 012 continues to move downwards until the base plate 2011 contacts the mounting surface to complete the adjustment. When all base plates 2011 are in contact with the mounting surface, the low-noise dry-type transformer 1 reaches a balanced state, ensuring the overall center of gravity is stable and preventing the core components such as the iron core and windings from bearing uneven stress due to uneven installation. During the operation of the low-noise dry-type transformer 1, the spring damper 2013 absorbs the vibration energy transmitted from its own operation and the outside world, reducing the impact on the internal structure and reducing noise. When encountering complex geological conditions such as earthquakes, the anti-vibration bracket 3 and the balancing mechanism 2 work together, and the adjusting component 206 adjusts and cooperates with the spring damper 2013 to buffer, so that the low-noise dry-type transformer 1 adapts to changes in ground vibration, maintains relative stability, avoids damage, reduces the risk of short-circuit faults, and ensures the normal operation of the power system.
