Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a reinforced transformer with winding fixation to prevent loosening. Background Technology

[0002] As a key piece of equipment in the power system, the stable operation of transformers is crucial. From a functional perspective, the windings are the "bridge" for electrical energy conversion. The basic principle of a transformer is electromagnetic induction; the windings achieve voltage transformation, current transformation, and impedance transformation through electromagnetic coupling. When the primary winding is connected to a power source, it generates an alternating magnetic flux. The secondary winding cuts this magnetic flux, generating an induced electromotive force, thus completing the transfer of electrical energy from the primary to the secondary side. Without windings, the transformer's voltage regulation and power transmission functions would be impossible, and voltage level matching and power distribution throughout the power system would be impossible.

[0003] A dry-type transformer is disclosed in a related technology (announcement number: CN207977191U). The disclosed technical solution is as follows: by setting up a fan and starting the fan, the air is blown into the device through the air diffuser and the first screen plate. At the same time, the movable plate is pulled out of the cover to cool the inside of the device. This timely removes the heat generated by the dry-type transformer during use, increases the heat dissipation speed of the device, effectively prevents damage to the internal structure of the device, and avoids safety problems.

[0004] The aforementioned disclosed technical solutions reveal the following problems: During transformer operation, the windings are prone to loosening due to the combined effects of electromagnetic forces, vibrations, temperature changes, and mechanical stresses. Winding loosening not only causes abnormal noise and vibration during transformer operation, affecting the stability and reliability of power transmission, but may also lead to serious problems such as localized overheating and insulation damage, thereby shortening the transformer's service life and even causing safety accidents. To address this, we propose a reinforced transformer with a winding fixation mechanism to prevent loosening.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of loose transformer windings in the prior art, this utility model provides a reinforced transformer with a winding fixing and anti-loosening structure. This structure combines a winding reinforcement structure with an anti-loosening structure to ensure the safe operation of the transformer. The specific technical solution is as follows:

[0007] A reinforced transformer for fixing and preventing loosening of windings includes a transformer body. The inner cavity of the transformer body is embedded with equally spaced sealing partitions. The inner cavity of the transformer body is uniformly formed into winding cavities by the equally spaced sealing partitions. Each winding cavity has an anti-loosening frame slidably disposed on its inner wall, located on both sides of the winding. The outer wall of each anti-loosening frame is fixedly connected to an I-shaped slide that slides laterally into the inner wall of the winding cavity. An interlocking telescopic frame is formed between the I-shaped slides located on both sides of each sealing partition. The outer wall of the transformer body is provided with a linkage component that drives all anti-loosening frames to move towards the winding.

[0008] In the above technical solution, the linkage component includes a retractable member that drives the two anti-loosening frames inside each winding cavity to move towards each other, and the outer wall of the transformer body is provided with a synchronous reinforcement member that drives all the retractable members synchronously.

[0009] The recessed component includes a transmission frame that is rotatably connected to two I-shaped slides inside each winding cavity. The other end of each of the two transmission frames is rotatably connected to an active frame that penetrates the side wall of the transformer body, and all the active frames are connected to the synchronous reinforcement component.

[0010] The synchronous reinforcement component includes a linkage frame that is connected to the ends of all active frames extending outside the transformer body, and the outer wall of the transformer body is rotatably provided with studs that are threadedly connected to the linkage frame.

[0011] The outer wall of the transformer body is fixedly connected to a guide post parallel to the stud, and the outer wall of the linkage frame is fixedly connected to a directional guide seat sleeved on the outer wall of the guide post.

[0012] Each of the sealing partitions has a through groove on the lower part of its side wall, and a limit seat is rotatably provided on the inner wall of the through groove, and the limit seat is used to fasten two adjacent windings.

[0013] The inner walls of the transformer body are slidably equipped with reinforcing claws for limiting the bottom of the windings.

[0014] The inner wall of the transformer body is provided with a guide groove, and the side wall of the reinforced claw frame is fixed with a guide block that is slidably disposed on the inner wall of the guide groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: a reinforced transformer with a fixed winding to prevent loosening.

[0016] 1. The transformer interior is divided into independent winding cavities by a sealed partition, so that the three-phase windings do not interfere with each other and avoid the risk of vibration transmission and loosening caused by interaction; the anti-loosening bracket, together with the I-shaped slide, forms a lateral clamp from both sides of the winding, and the limiting seat and the reinforcing claw bracket achieve longitudinal fixation from the bottom, forming a three-dimensional fixing structure of "side clamp + bottom fixation", which restricts the displacement and shaking of the winding in all directions and solves the problem of insufficient anti-loosening effect of traditional single fixing method.

[0017] Second, the linkage assembly, through the coordinated action of studs, linkage frame and transmission frame, can drive the anti-loosening frames in all winding cavities to move synchronously in opposite directions, ensuring that the clamping force on each winding is consistent, and avoiding winding deformation or fixation failure due to uneven local force; the I-shaped slide's sleeve design reduces the lateral space occupation, while improving sliding stability, making the anti-loosening frame fit the winding better.

[0018] Third, the retraction component adopts a hinged structure of transmission frame and drive frame, which can flexibly adjust the clamping range of anti-loosening frame according to the winding size and adapt to coils of different specifications; the through groove design of the sealing partition facilitates the rotation operation of the limit seat, and the reinforced claw frame is slidably adjusted through the T-shaped guide groove to meet the fixing requirements of different winding bases and improve the versatility of the device.

[0019] Fourth, the independent winding cavity reduces electromagnetic interference and heat transfer between windings, improving operational stability; the tight fit between the anti-loosening bracket and the winding avoids insulation wear and short-circuit risks caused by coil loosening, extending the service life of the transformer and ensuring the safe operation of the power system.

Detailed Implementation

[0026] 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.

[0027] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0028] A reinforced transformer for fixing and preventing loosening of windings includes a transformer body 1. Equally spaced sealing partitions 2 are embedded in the inner cavity of the transformer body 1, forming winding cavities 3 evenly distributed within the cavity. Two sealing partitions 2 are fixedly embedded inside the transformer body 1, dividing the transformer interior into three independent winding cavities 3. These winding cavities 3 are used to fix the windings, ensuring that the three windings of the three-phase transformer are independently located within their respective spaces, thus improving the protection effect.

[0029] Each winding cavity 3 has an anti-loosening bracket 4 slidably mounted on its inner wall, located on both sides of the winding. An I-shaped slide 5, which slides laterally into the inner wall of the winding cavity 3, is fixed to the outer wall of the anti-loosening bracket 4. Each anti-loosening bracket 4 has an I-shaped slide 5 fixedly mounted on its outer wall. The I-shaped slide 5 consists of one longitudinal and two parallel transverse supports, forming an "I" shape. The longitudinal support is fixed to the outer wall of the anti-loosening bracket 4, while the two transverse supports slide within movable holes in the inner wall of the transformer body 1. The I-shaped slides 5 on both sides slide laterally on the inner wall of the transformer body 1. The anti-loosening bracket 4 is located above the inside of the winding cavity 3, tightening the coil at the top of the winding and preventing the coil on the outer wall of the winding from loosening and falling off.

[0030] The I-shaped slides 5 located on both sides of each sealing partition 2 form an interlocking telescopic frame. The cavity of the winding cavity 3 is surrounded by the inner wall of the transformer and the sealing partition 2, so that the transverse support of the I-shaped slide 5 on the side away from the inner wall of the transformer passes through the inner cavity of the sealing partition 2, and the transverse support of the I-shaped slide 5 slides in the through hole of the sealing partition 2. The diameter of the transverse support of the I-shaped slide 5 in the winding cavity 3 is larger than the diameter of the adjacent transverse support on the right, so that the transverse support of each I-shaped slide 5 is sequentially sleeved on the outer wall of the transverse support of the adjacent I-shaped slide 5, reducing the transverse space occupied by two adjacent I-shaped slides 5.

[0031] The outer wall of the transformer body 1 is equipped with a linkage component that drives all the anti-loosening brackets 4 to move toward the winding. Through the linkage component outside the transformer body 1, all the I-shaped slides 5 drive the anti-loosening brackets 4 to move toward the outer wall of the winding, so that the two anti-loosening brackets 4 in each winding cavity 3 move relative to each other, thereby sticking to the outer wall of the coil and preventing the coil from loosening and falling off, thus protecting the transformer.

[0032] The linkage assembly includes a retractable component that drives two anti-loosening frames 4 inside each winding cavity 3 to move towards each other, and a synchronous reinforcement component that drives all retractable components synchronously on the outer wall of the transformer body 1. Each winding cavity 3 has a retractable component on its rear side, and each retractable component can drive two anti-loosening frames 4 to move towards each other simultaneously. The external synchronous reinforcement component ensures that each pair of anti-loosening frames 4 inside the three winding cavities 3 moves simultaneously towards the outer wall of the winding, preventing the coils from loosening and falling off while maintaining the stability of each winding's position.

[0033] It is worth noting that the recessed component includes a transmission frame 6 that is rotatably connected to two I-shaped slides 5 inside each winding cavity 3. The other end of each of the two transmission frames 6 is rotatably connected to an active frame 7 that penetrates the side wall of the transformer body 1, and all active frames 7 are connected to the synchronous reinforcement component.

[0034] The active frame 7 extends through the outer wall of the transformer body 1 into the interior. The shaft of the active frame 7 is installed at one end inside the transformer. The ends of all active frames 7 located outside the transformer are fixedly connected to the linkage frame 8. One end of each of the two rotating frames 6 is movably sleeved on the outer wall of the shaft at the end of the active frame 7 through the mounting holes opened by the connector. The other ends of the two transmission frames 6 are respectively hinged to the I-shaped slides 5 on both sides of the winding.

[0035] The synchronous reinforcement component includes a linkage frame 8 connected to the ends of all the active frames 7 extending outside the transformer body 1. A stud 9 is rotatably provided on the outer wall of the transformer body 1 and threadedly connected to the linkage frame 8. The stud 9 rotates on the outer wall of the transformer body 1, and a movable seat is fixedly installed on the linkage frame 8. The movable seat is threadedly connected to the stud 9 through a threaded through hole.

[0036] After the windings are installed inside each winding cavity 3, the stud 9 is turned so that the movable seat threaded to the stud 9 moves the linkage frame 8. The linkage frame 8 simultaneously drives the three active frames 7 to slide in the through hole of the transformer. As the active frames 7 move, they drive one end of the two simultaneously hinged transmission frames 6 to move. The other end of the transmission frames 6 drives the hinged I-shaped slide 5 to move. The I-shaped slide 5 slides on the inner wall of the winding cavity 3, so that the two loose frames 4 in each winding cavity 3 move relative to each other and fit against the outer wall of the winding.

[0037] In addition, a guide post 10 parallel to the stud 9 is fixedly connected to the outer wall of the transformer body 1, and a directional guide seat 11 sleeved on the outer wall of the linkage frame 8 is fixedly connected to the outer wall of the guide post 10. The directional guide seat 11 is movably sleeved on the outer wall of the guide post 10 through an opening in the mounting hole.

[0038] During the process of rotating the stud 9 to move the linkage frame 8, the linkage frame 8 causes the directional guide seat 11 to slide against the outer wall of the guide post 10. The guide post 10, which is parallel to the stud 9, ensures the stability of the movement direction of the linkage frame 8.

[0039] In addition, a through groove 12 is provided on the lower part of the side wall of each sealing partition 2, and a limiting seat 13 for fastening the bottom of the winding inside the two adjacent winding cavities 3 is rotatably provided on the inner wall of the through groove 12. The limiting seat 13 rotates laterally on the inner wall of the through groove 12. When installing the winding, the limiting seat 13 on the inner wall of the through groove 12 is rotated to a position parallel to the sealing partition 2.

[0040] After placing the winding into the winding cavity 3, rotate the limiting seat 13 on the inner wall of the through slot 12 to rotate the limiting seat 13 above the winding base. Then, fix the limiting seat 13 to the winding base by passing bolts through the mounting holes on the limiting seat 13. This further strengthens the stability of the winding within the transformer.

[0041] Furthermore, both sides of the inner wall of the transformer body 1 are slidably provided with reinforcing claw brackets 14 for limiting the bottom of the winding. After the winding is installed into the corresponding winding cavity 3, the two reinforcing claw brackets 14 on both sides of the inner wall of the transformer body 1 are slid to the position of being attached to the top of the winding base, and then the bolts on the reinforcing claw brackets 14 are tightened to fix them to the winding, thereby improving the stability of the winding.

[0042] The inner wall of the transformer body 1 is provided with a guide groove 15, and the side wall of the reinforcing claw 14 is fixedly connected with a guide block 16 that is slidably disposed on the inner wall of the guide groove 15. The transverse cross-section of the guide groove 15 and the guide block 16 is T-shaped to prevent the reinforcing claw 14 from detaching from the inner wall of the transformer body 1.
