Description

Technical Field

[0001] This invention relates to the field of transformer equipment manufacturing, and in particular to a high-power three-phase transformer duct fabrication equipment. Background Technology

[0002] In power systems, high-power three-phase transformers are core equipment for power conversion and transmission. Their operating efficiency, heat dissipation performance, and stability directly affect the safe and reliable operation of the entire power network. With the continuous growth of electricity demand, transformer capacity continues to increase, and the heat generated during operation increases significantly. Therefore, a reasonable heat dissipation structure design has become crucial to ensuring their efficient operation.

[0003] As a crucial component of the transformer's internal heat dissipation system, the structural rationality and dimensional accuracy of the air duct play a decisive role in the heat dissipation effect. Traditionally, the fabrication of air ducts for high-power three-phase transformers often employs fixed mold winding or manual adjustment. However, these methods have significant limitations: firstly, fixed molds are difficult to adapt to flexible adjustments in duct dimensions for different power ratings and heat dissipation requirements. When transformer parameters change, custom molds must be made, increasing production costs and extending the production cycle. Secondly, manual adjustment methods have low precision, making it difficult to ensure the consistency of the duct's perimeter, easily leading to deviations in the duct's cross-sectional dimensions, affecting the uniformity of airflow, thus reducing heat dissipation efficiency, and potentially even causing equipment failure due to localized overheating.

[0004] Furthermore, existing duct fabrication processes suffer from insufficient stability and ease of adjustment in coil winding. As the fundamental component of duct winding, precise control of the coil's circumference is crucial for ensuring the duct's dimensions meet specifications. Traditional coil structures lack effective adjustment mechanisms, failing to accurately alter the circumference through the combined action of linear movement and lifting adjustment according to actual needs. This results in ducts that are difficult to match the complex internal spatial layout of transformers, impacting overall assembly quality. Simultaneously, poor connection stability and interoperability between adjustment components lead to issues such as adjustment lag and jamming, further reducing the efficiency and reliability of duct fabrication.

[0005] Therefore, in order to address the problems of poor flexibility in size adjustment, insufficient precision, low production efficiency, and poor structural stability in the existing high-power three-phase transformer duct manufacturing, it is necessary to develop a method that can achieve efficient duct winding by precisely adjusting the coil circumference. This has become an urgent technical need in the current transformer manufacturing field, and is of great significance for improving the heat dissipation performance of transformers, reducing production costs, and shortening the production cycle. Summary of the Invention

[0006] This invention provides a high-power three-phase transformer duct fabrication device, comprising: A coil, wherein an adjustment device is provided on the coil, the adjustment device moves linearly on the coil, a lifting groove is provided on the coil corresponding to the position of the adjustment device, the adjustment device is located in the lifting groove, and an adjustment channel is provided on the side of the lifting groove, the adjustment channel being connected to the lifting groove; An adjusting component is assembled with the adjusting device through the adjusting channel, and the adjusting component drives the adjusting device to move up and down within the lifting groove; The adjusting device adjusts the circumference of the coil by lifting, so that the wire is wound through the coil to form an air duct.

[0007] Preferably, in this embodiment of the application, the adjusting device includes: A lifting plate is mounted on the coil, with one side surface of the lifting plate abutting against the outer surface of the coil; A lifting component is disposed on the other side surface of the lifting plate. The lifting component has a first abutting surface. The lifting component is located in the lifting groove. The first abutting surface is disposed corresponding to the position of the adjustment channel. The adjustment component abuts against the first abutting surface in the adjustment channel to drive the lifting component to rise and fall in the lifting groove, so that the lifting component drives the lifting plate to rise and fall.

[0008] Preferably, in this embodiment of the application, multiple adjustment channels are provided, and the multiple adjustment channels are linearly and evenly arranged on the side of the lifting groove; The lifting components are provided in multiple ways, and the number of lifting components corresponds to the number of adjustment channels. The multiple lifting components are connected by a connecting device, so that when one of the lifting components is pushed, the pushed lifting component pushes the other lifting components and the lifting plate to move up and down in the lifting groove.

[0009] Preferably, in this embodiment of the application, the first abutting surface is set as an inclined surface, and the vertical height of the inclined surface of the first abutting surface is less than the height of the adjustment channel.

[0010] Preferably, in this embodiment of the application, the distance between adjacent adjustment channels is equal to the sum of the distance between adjacent lifting members and the vertical distance of the first contact surface.

[0011] Preferably, in this embodiment of the application, the thickness of the adjusting member is equal to the thickness of the adjusting channel, and a second abutting surface is provided on the adjusting member at a position corresponding to the first abutting surface. The first abutting surface is parallel to the second abutting surface. When the adjusting member moves in the adjusting channel, the second abutting surface pushes the first abutting surface, causing the first abutting surface to slide relative to the second abutting surface. The lifting member drives the lifting plate to rise in the lifting groove.

[0012] Preferably, in this embodiment of the application, the connecting device includes: A connecting block is disposed on one end of the lifting member away from the first abutment surface. Positioning blocks and positioning grooves are provided on both sides of the connecting block relative to one end of the lifting member. The positioning blocks are connected to the adjacent positioning grooves, so that two adjacent lifting members are connected. A limiting device is provided on the positioning block and the positioning groove, and the adjacent lifting components are limited by the limiting device.

[0013] Preferably, in this embodiment of the application, the limiting device includes: A limiting groove is provided on the positioning block, and multiple limiting grooves are provided on the positioning block; A limiting block is provided in the positioning groove. When adjacent lifting components are connected, the limiting block is provided in the limiting groove so that adjacent lifting components are connected. The width of the limiting groove is equal to the width of the limiting block, thereby limiting the horizontal movement of the adjacent lifting components. The height of the limiting groove is greater than the height of the limiting block, allowing the positioning block to move up and down within the positioning groove, thereby causing the adjacent lifting components to rise and fall.

[0014] Preferably, in this embodiment of the application, the limiting device further includes: An anti-loosening structure is disposed between the limiting block and the limiting groove, the anti-loosening structure being used to limit the accidental movement of the limiting block within the limiting groove.

[0015] Preferably, in this embodiment of the application, the anti-loosening structure includes: An elastic element is disposed within the limiting groove; The top bead is partially housed within the elastic element; When the limiting block is inserted into the limiting groove and reaches the set position, the top bead abuts against the side wall of the limiting block under the action of the elastic element.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. This invention achieves precise, step-by-step adjustment of the coil circumference through the coordinated design of lifting grooves, adjusting devices, and adjusting components on both sides of the coil. The adjusting components push the first contact surface of the lifting components through the adjusting channel, causing the lifting plate to rise and fall, thereby changing the overall circumference of the coil. This allows for direct adaptation to the air duct size requirements of different transformer models. It eliminates the need for custom-made molds for different models, significantly reducing production costs and shortening the production cycle caused by mold changes, thus improving the equipment's versatility and production efficiency.

[0017] 2. In the adjustment device, the lifting plate is fitted into the fixed groove to form an integral part with the coil, ensuring the flatness of the coil surface during winding. The lifting components correspond one-to-one with the adjustment channels, and the parallel design of the first and second contact surfaces ensures the stability and accuracy of the adjustment process. This effectively avoids the circumference deviation problem that easily occurs in traditional manual adjustment methods, ensures consistent cross-sectional dimensions of the wound air duct, improves the uniformity of heat dissipation airflow, thereby enhancing the transformer's heat dissipation efficiency and reducing the risk of failure caused by localized overheating.

[0018] 3. The connecting device connects adjacent lifting components through the engagement of positioning blocks and positioning grooves. Combined with the snap-fit ​​structure of limit blocks and limit grooves, this restricts the horizontal offset of the lifting components, ensuring stable movement only in the vertical direction and avoiding problems such as jamming and misalignment during adjustment. The design of the elastic element and top ball in the anti-loosening structure further prevents accidental movement of the limit blocks within the limit grooves, ensuring the consistency of linkage between the lifting components. This significantly improves the structural stability and adjustment reliability of the adjusting device, reduces adjustment lag, and enhances the continuity and efficiency of duct fabrication.

[0022] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] like Figures 1 to 8 As shown in the figure, an embodiment of the present invention provides a high-power three-phase transformer duct manufacturing device, including a coil 100 and an adjusting component 200. Lifting grooves 110 are respectively provided on both sides of the coil 100. An adjusting device 300 is provided in the lifting groove 110. The adjusting device 300 can be raised and lowered within the lifting groove 110 by adjusting the adjusting component 200 step by step. The raising and lowering adjustment of the adjusting device 300 can adjust the overall circumference of the coil 100, so as to make wire ducts of different circumferences to adapt to different models of transformers.

[0024] In the above structure, the adjusting device 300 mainly includes a lifting plate 310 and lifting components 320. Multiple lifting components 320 are provided, and they are evenly and linearly arranged on one side of the lifting plate 310. The lifting plate 310 is mounted on the coil 100, specifically at the opening of the lifting groove 110, so that one side surface of the lifting plate 310 abuts against the outer surface of the coil 100, facilitating the winding of the coil 100. A fixed groove 130 is formed at the opening of the lifting groove 110. The depth and corresponding area of ​​the fixed groove 130 match the lifting plate 310, so that the lifting plate 310 can be fitted into the fixed groove 130 and form a whole with the coil 100, which facilitates the winding of the silk thread on the coil 100.

[0025] A lifting component 320 is provided on one side of the lifting groove 110 on the lifting plate 310. Multiple lifting components 320 are provided and are linearly arranged in the lifting groove 110 along the depth direction of the lifting groove 110. Multiple adjustment channels 120 are also provided on the side of the lifting groove 110. The number of adjustment channels 120 corresponds to the number of lifting components 320, so that each lifting component 320 is set in a position corresponding to the adjustment channel 120. The multiple adjustment channels 120 are linearly and evenly arranged on the side of the lifting groove 110.

[0026] A first abutment surface 321 is provided on the lifting member 320. The first abutment surface 321 is obliquely arranged on the lifting member 320, and the oblique position of the first abutment surface 321 is located away from the lifting plate 310. The vertical height of the first abutment surface 321 is less than the height of the adjustment channel 120, so that when the adjusting member 200 moves in the adjustment channel 120, the end of the adjusting member 200 facing the first abutment surface 321 abuts against the first abutment surface 321, so that the adjusting member 200 pushes the first abutment surface 321, thereby pushing the lifting plate 310.

[0027] The structures upon which the above process depends include: After the adjusting member 200 abuts against the first abutting surface 321, at least one first abutting surface 321 must be positioned corresponding to the adjustment channel 120. In this embodiment, when there is no adjusting member 200 in the adjustment channel 120, the first abutting surface 321 on the lifting member 320 at the bottom of the lifting groove 110 is positioned corresponding to the adjustment channel 120 to facilitate the first adjusting member 200 pushing against the first abutting surface 321. When the adjusting member 200 pushes against the first abutting surface 321, the end of the adjusting member 200 abuts against the first first abutting surface 321, causing the first lifting plate 310 corresponding to the first abutting surface 321 to rise. When the adjusting member 200 is fully inserted into the adjustment channel 120, the adjusting member 200 stops. The first lifting plate 310 is raised. At this time, a second lifting plate 310 is set above the first lifting plate 310 at this position, so that the lifting of the first lifting plate 310 drives the lifting of the second lifting plate 310. After the second lifting plate 310 is raised, the first abutting surface 321 on the second lifting plate 310 is set to correspond to the second adjustment channel 120. When the second adjustment member 200 abuts against the first abutting surface 321 on the second lifting plate 310, the second lifting member 320 is abutted and moved upward by the second adjustment member 200, so that the second lifting member 320 pushes the third lifting member 320 above it to move upward. In this way, it can move upward until it moves to a lifting member 320 connected to the lifting plate 310, thus completing the rising process of the lifting plate 310.

[0028] During the aforementioned lifting process, when the first lifting component 320 is raised, all lifting components 320 on the first lifting component 320 will rise synchronously. At this time, the lifting plate 310 rises by the distance of its adjusting component 200.

[0029] In this embodiment, the thickness of the adjusting member 200 is less than or equal to the height of the adjusting channel 120. A second abutting surface 210 is provided on the adjusting member 200 at the position corresponding to the first abutting surface 321. When the adjusting member 200 is in the adjusting channel 120, the first abutting surface 321 is parallel to the second abutting surface 210. When the adjusting member 200 moves in the adjusting channel 120, the second abutting surface 210 pushes the first abutting surface 321, causing the first abutting surface 321 to slide relative to the second abutting surface 210. During the sliding process, the lifting member 320 will be raised, causing the lifting member 320 to drive the lifting plate 310 to rise in the lifting groove 110.

[0030] Whenever an adjusting element 200 is inserted into the adjusting channel 120 to abut against the lifting element 320, the lifting plate 310 rises to the height corresponding to the number of adjusting elements 200.

[0031] In this embodiment of the application, in order to complete the above process, the distance between adjacent adjustment channels 120 is equal to the sum of the distance between adjacent lifting members 320 and the vertical distance of the first contact surface 321.

[0032] In this embodiment, since the lifting components 320 are arranged in an orderly manner, when placing the lifting components 320 within the coil 100, they need to be connected to each lifting component 320 via a connecting device 400. This ensures that when one lifting component 320 is pushed, it pushes the other lifting components 320 and the lifting plate 310 to move up and down within the lifting groove 110. This also prevents the lifting components 320 from becoming loose. Specifically: The connecting block 410 and the limiting device 420 are part of the connecting device 400. The connecting block 410 is located at one end of the lifting member 320 away from the first abutment surface 321. The positioning block 411 and the positioning groove 412 are located on both sides of the connecting block 410 relative to one end of the lifting member 320. The positioning block 411 is connected to the adjacent positioning groove 412, so that two adjacent lifting members 320 are connected.

[0033] The limiting device 420 includes multiple limiting blocks 422 and limiting grooves 421. The multiple limiting blocks 422 are disposed in the positioning grooves 412, and the multiple limiting grooves 421 are disposed on the positioning blocks 411. When adjacent lifting components 320 are connected through the positioning blocks 411 and the positioning grooves 412, the limiting blocks 422 match the limiting grooves 421 on the adjacent lifting components 320, that is, the limiting blocks 422 are located in the limiting grooves 421, so that the adjacent lifting components 320 can be connected by the snap-fit ​​between the limiting blocks 422 and the limiting grooves 421, and the adjacent lifting components 320 can be limited by the snap-fit ​​between the limiting blocks 422 and the limiting grooves 421, so as to avoid misalignment or displacement between the adjacent lifting components 320, and improve the connection stability and linkage between the lifting components 320.

[0034] When the lifting component 320 is lifting, the limiting block 422 slides in the limiting groove 421. Since the width of the limiting groove 421 is equal to the width of the limiting block 422, the limiting block 422 can limit the lifting component 320 in the horizontal direction when it slides in the limiting groove 421, so that the lifting component 320 can only move in the vertical direction, avoiding the horizontal deviation of the lifting component 320 during the lifting process, and further improving the lifting stability of the lifting component 320.

[0035] Meanwhile, the height of the limiting groove 421 is greater than the height of the limiting block 422, allowing the limiting block 422 to move up and down within the limiting groove 421, thereby driving the adjacent lifting components 320 to rise and fall, thus realizing the linkage adjustment between the lifting components 320.

[0036] In addition, to prevent the limiting block 422 from moving unexpectedly within the limiting groove 421, an anti-loosening structure 423 is provided between the limiting block 422 and the limiting groove 421 in this embodiment. The anti-loosening structure 423 is part of the limiting device 420. The anti-loosening structure 423 includes an elastic element 4231 and a top bead 4232. The elastic element 4231 is disposed within the limiting groove 421, and the top bead 4232 is partially accommodated within the elastic element 4231.

[0037] When the limiting block 422 is inserted into the limiting groove 421 and reaches the set position, the top bead 4232 presses against the side wall of the limiting block 422 under the action of the elastic element 4231, thereby limiting the accidental movement of the limiting block 422 in the limiting groove 421 and improving the stability and reliability of the limiting device 420.

[0038] In summary, the high-power three-phase transformer duct manufacturing equipment provided by the present invention achieves precise adjustment of the circumference of the coil 100 by setting an adjustment device 300 and an adjustment component 200 on the coil 100, thereby enabling the manufacture of ducts with different circumferences to adapt to different transformer models.

[0039] Meanwhile, the structural design of the regulating device 300 and the regulating component 200 is reasonable, the regulating process is stable and reliable, and the regulating components 200 are connected and limited by the connecting device 400, which further improves the efficiency and reliability of the air duct manufacturing.

[0040] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
