Abstract
Description
Technical Field
[0001] This invention relates to the field of transformer technology, and more specifically to a transformer coil assembly based on an axial clamping block linkage structure. Background Technology
[0002] Transformers are crucial equipment in power systems, and one of their core components is the transformer coil assembly. The transformer coil assembly typically consists of various parts such as insulating cylinders, conductors, support bars, end rings, and insulating blocks.
[0003] In traditional manufacturing processes, coil winding and clamping are two separate steps. After the wire is wound on a dedicated winding machine, the entire coil is clamped by a clamping mechanism.
[0004] However, in the actual winding process, not all conductors are completely wound around the entire circumference of the insulating cylinder. That is, they are not completely wound or only partially wound. For this type of coil, if the upper and lower ends of the conductors are not immediately tightened and fixed after the winding process is completed, these suspended or not fully constrained conductor ends are easily affected by external forces or their own weight during subsequent hoisting and transfer, causing them to sway and shift. This swaying will directly cause the originally neatly arranged conductors to become loose, resulting in quality problems such as loose winding and deformation of the coil, which in turn affects the electrical performance and mechanical stability of the transformer. Summary of the Invention
[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a transformer coil assembly based on an axial clamping block linkage structure. This effectively solves the problem that, in the actual winding process, not all conductors are completely wound around the entire circumference of the insulating cylinder, resulting in incomplete or partial winding. For such coils, if the upper and lower ends of the conductors are not immediately clamped and fixed after the winding process, these suspended or unconstrained conductor ends are easily affected by external forces or their own weight during subsequent hoisting and transfer, causing them to sway and shift. This swaying directly leads to the originally neatly arranged conductors becoming loose, resulting in quality problems such as loose winding and coil deformation, which in turn affects the electrical performance and mechanical stability of the transformer.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] This invention provides a transformer coil assembly based on an axial clamping block linkage structure, comprising:
[0008] An insulating cylinder has a wire wound around its outer circumference in the vertical direction, and end rings with placement holes are provided at both the top and bottom ends of the insulating cylinder.
[0009] The clamping mechanism is located inside the insulating cylinder to clamp and limit the wire after winding.
[0010] The adjusting cylinder is located inside the insulating cylinder, and two threaded grooves with opposite directions are formed along the outer circumference of the adjusting cylinder.
[0011] The outer circumference of the insulating cylinder is provided with several sliding grooves in a symmetrical manner, and a support bar is provided between adjacent sliding grooves.
[0012] The clamping mechanism includes a clamping component that is slidably disposed inside several sliding grooves and an adjusting component that is connected to the threaded groove on the adjusting cylinder. During operation, the adjusting cylinder moves synchronously with the clamping component and the clamping component to achieve the clamping of the wire after winding.
[0013] Furthermore, a limiting groove is formed on the upper and lower sides of the support bar, and a sliding rod is provided inside the limiting groove along the vertical direction.
[0014] Furthermore, the clamping assembly includes a mounting plate that is slidably sleeved on the outer wall of the slide rod and connected to the limiting groove by a compression spring. The mounting plate is provided with a receiving groove at the position corresponding to the sliding groove on the insulating cylinder, and an actuator for clamping and limiting the conductor is provided inside the receiving groove.
[0015] Furthermore, the actuator includes a bearing block disposed inside the receiving groove in the vertical direction, and a clamping block with a waist-shaped groove on its end face is slidably disposed inside the receiving groove. A support rod that penetrates the bearing block and has a top pressure spring disposed on its outer circumference is disposed inside the waist-shaped groove.
[0016] Furthermore, the adjustment assembly includes an adjustment frame that is always threadedly connected to the adjustment cylinder. The side of the adjustment frame away from the adjustment cylinder is connected to the mounting plate through several sliding connecting blocks. The adjustment frame is provided with auxiliary components for adjusting the position of the clamping block.
[0017] Furthermore, the auxiliary component includes an auxiliary frame rotatably connected to the adjustment frame. Several push blocks that cooperate with the clamping blocks are arranged on the auxiliary frame along the circumferential direction. The top of the auxiliary frame is connected to a rotating disk with several mating grooves on the end face along the circumferential direction through several telescopic rods. The rotating disk is rotatably connected to the end ring.
[0018] Furthermore, the top and bottom of the regulating cylinder are each provided with a drive disc that is rotatably connected to the rotating disk, and the ends of the two drive discs that are far apart are each provided with several limiting holes along the circumferential direction.
[0019] Furthermore, the mating groove assembly includes several circular holes, wherein locking brackets are collectively provided within the circular holes, placement holes, and limiting holes.
[0020] The technical solution provided by this invention has the following advantages compared with the prior art:
[0021] This invention integrates the pressing process into the winding equipment. After the conductor is wound on the support bar of the insulating cylinder, the entire coil assembly does not need to be disassembled or moved from the winding machine. During the rotation of the drive disc, the adjusting cylinder is driven to rotate. Through the transmission characteristics of the positive and negative threads on the cylinder, the upper and lower adjusting frames are driven to move synchronously in opposite directions. The adjusting frames, through the connecting block and the mounting plate, drive all the pressing blocks to move axially until they are evenly pressed on the upper and lower end faces of the coil. In this way, the large amount of auxiliary time spent on hoisting and transferring the coil in the traditional process is eliminated, the production cycle is greatly reduced, and the overall production efficiency is significantly improved. More importantly, it fundamentally eliminates the quality risks such as conductor misalignment, interlayer slippage, and even structural loosening caused by vibration and collision when the coil is transferred in an unfixed state. This lays a solid mechanical foundation for the stable progress of subsequent processes and the final quality of the transformer. Attached Figure Description

[0034] Example:
[0035] Please see Figure 1 - Figure 7 This invention provides a technical solution: a transformer coil assembly based on an axial clamping block linkage structure, comprising:
[0036] An insulating cylinder 1 has a wire 11 wound around its outer circumference in the vertical direction, and an end ring 12 with a placement hole 121 on its end face is provided at both the top and bottom ends of the insulating cylinder 1.
[0037] The clamping mechanism 2 is located inside the insulating cylinder 1 and is used to clamp and limit the wire 11 after winding.
[0038] Adjusting cylinder 3 is located inside insulating cylinder 1, and two threaded grooves 31 with opposite directions are formed along the outer circumference of the adjusting cylinder 3.
[0039] Among them, the outer circumferential wall of the insulating cylinder 1 is provided with several sliding grooves 13 in a symmetrical manner, and a support bar 14 is provided between adjacent sliding grooves 13.
[0040] The clamping mechanism 2 includes a clamping component 21 that is slidably disposed inside several sliding grooves 13 and an adjusting component 22 that is connected to the threaded groove 31 on the adjusting cylinder 3. During operation, the adjusting cylinder 3 moves synchronously with the adjusting component 22 and the clamping component 21, and the clamping of the wire 11 after winding is achieved through the clamping component 21.
[0041] A limiting groove 141 is provided on the upper edge of the support bar 14 in the vertical direction, and a sliding rod 142 is provided inside the limiting groove 141 in the vertical direction.
[0042] The clamping assembly 21 includes a mounting plate 211 that is slidably sleeved on the outer wall of the slide rod 142 and connected to the limiting groove 141 by a compression spring 2111. The mounting plate 211 has a receiving groove 2112 at the position corresponding to the sliding groove 13 on the insulating cylinder 1. The receiving groove 2112 has an actuator 212 inside for clamping and limiting the wire 11.
[0043] The actuator 212 includes a support block 2121 disposed inside the receiving groove 2112 along the vertical direction. A pressing block 2122 with a waist-shaped groove 2123 on its end face is also slidably disposed inside the receiving groove 2112. A support rod 2124 is disposed inside the waist-shaped groove 2123, which passes through the support block 2121 and has a top pressure spring 2125 disposed on its outer circumference.
[0044] The adjustment assembly 22 includes an adjustment frame 221 that is always threadedly connected to the adjustment cylinder 3. The side of the adjustment frame 221 away from the adjustment cylinder 3 is connected to the mounting plate 211 through a number of sliding connecting blocks 222. The adjustment frame 221 is provided with auxiliary parts 223 for adjusting the position of the pressing block 2122.
[0045] The auxiliary component 223 includes an auxiliary frame 2231 rotatably connected to the adjustment frame 221. The auxiliary frame 2231 has several push blocks 2232 arranged along the circumferential direction to cooperate with the pressing block 2122. The top of the auxiliary frame 2231 is connected to a rotating disk 2233 with several mating grooves on its end face along the circumferential direction through several telescopic rods 2235. The rotating disk 2233 is rotatably connected to the end ring 12.
[0046] The top and bottom of the regulating cylinder 3 are provided with driving disks 32 that are rotatably connected to the rotating disk 2233. The ends of the two driving disks 32 that are far apart are provided with several limiting holes 321 along the circumferential direction.
[0047] The mating groove assembly includes several circular holes 2234, wherein a locking bracket 33 is provided in the circular holes 2234, the placement hole 121 and the limiting hole 321.
[0048] In specific work,
[0049] In the actual winding process, not all conductors 11 will be completely wrapped around the entire circumference of the insulating cylinder 1. That is, they are not completely wrapped or partially wound. For this type of coil, if the upper and lower ends of the conductors 11 are not immediately pressed and fixed after the winding process is completed, then during the subsequent hoisting and transfer process, the ends of these suspended or not fully constrained conductors 11 are very susceptible to shaking and displacement due to external forces or their own weight. This shaking will directly cause the originally neatly arranged conductors 11 to become loose, resulting in quality problems such as loose winding and coil deformation, which in turn affects the electrical performance and mechanical stability of the transformer. Based on this, the transformer coil assembly based on the axial pressing block linkage structure is equipped with a pressing component 21 and an adjusting component 22. After the winding of the conductors 11 is completed, there is no need to transfer the coil. The adjusting cylinder 3 synchronously drives the adjusting component 22 and the pressing component 21 to move, thereby realizing the pressing of the coil after winding.
[0050] Specifically, the outer circumferential wall of the insulating cylinder 1 is evenly provided with several support bars 14 along the circumferential direction. The support bars 14 provide support for the subsequently wound wires 11, so that they maintain a preset gap with the body of the insulating cylinder 1, thereby constructing a heat dissipation channel and an insulating oil circulation path. This is the basic structure to ensure the thermal stability and electrical insulation performance of the transformer during operation. On each support bar 14, two limiting grooves 141 are opened with the central axis as the center of symmetry. In the initial stage of the winding process, the mounting plate 211 used to install the clamping block 2122 is positioned in the corresponding limiting groove 141 at a position far away from each other, ensuring that the mounting plate 211 will not interfere with the smooth and continuous winding of the wires 11. When the coil winding work is completed, the coil assembly does not need to be removed from the winding equipment. At this time, the drive disk 32 is rotated, which in turn drives the adjusting cylinder 3 fixed to it to rotate synchronously. On the outer circumferential wall of the adjusting cylinder 3, two threaded grooves 31 with opposite directions of rotation and distributed vertically are opened. The inner walls of the upper and lower adjusting frames 221 are respectively fixed with threaded sleeves that mesh with the corresponding threaded grooves 31.
[0051] Therefore, when the adjusting cylinder 3 rotates under the drive of the drive disc 32, its forward and reverse thread transmission characteristics drive the upper and lower adjusting frames 221 to move synchronously towards each other along the axial direction of the adjusting cylinder 3. During this process, since the adjusting frame 221 is rigidly connected to the mounting plate 211 through several connecting blocks 222, the linear motion of the adjusting frame 221 will be synchronously transmitted to the mounting plate 211. To ensure that the mounting plate 211 only performs axial translation and does not rotate circumferentially, the mounting plate 211 is designed to slide on the outer wall of the slide rod 142 fixed on the support bar 14. The slide rod 142 constitutes a reliable linear guide and anti-rotation constraint. As the adjusting cylinder 3 continues to rotate, the mounting plate 211 drives the several pressing blocks 2122 arranged in an array on it to gradually and synchronously approach and finally press against the upper and lower end faces of the coil. Through this series of precise... The mechanical linkage allows for synchronous and uniform clamping and axial limiting of all positions at both ends of the coil by applying a single-direction rotational drive to the adjusting cylinder 3. Through the "pressing immediately after winding" design, the clamping process is integrated after winding is completed, achieving continuous operation and significantly reducing the production cycle and improving overall production efficiency. At the same time, it eliminates the risks of wire misalignment, interlayer slippage, and even structural loosening caused by vibration and collision during coil hoisting and transportation, laying a solid mechanical foundation for subsequent stable operation. On this basis, the synchronous and symmetrical clamping achieved by the single rotational drive of the adjusting cylinder 3 ensures that the force applied to both ends of the coil is uniform and consistent, effectively avoiding local stress concentration, coil deformation, or inter-turn insulation damage that may be caused by traditional manual or step-by-step clamping, thereby greatly improving the mechanical stability of the coil.
[0052] It should be noted that, in order to transmit and maintain the clamping force, and to produce slight deformation when in contact with the wire 11 to adapt to the unevenness of the wire 11 surface, increase the contact area, and disperse the pressure, the side of the clamping block 2122 that contacts the wire 11 is preferably made of silicone rubber with excellent elasticity, high temperature resistance and insulation.
[0053] Mounting plate 211 is slidably sleeved on the outer wall of slide rod 142 inside limiting groove 141. The bottom end of mounting plate 211 is connected to limiting groove 141 through compression spring 2111. In the initial state, when mounting plate 211 has not moved, compression spring 2111 is in a stretched state. Thus, after clamping block 2122 completes the clamping and limiting work on wire 11, the restoring force of compression spring 2111 can further increase the clamping force on wire 11. At the same time, the use of compression spring 2111 can also disperse the force on the coil during the subsequent operation, thereby improving the stability of the coil during operation.
[0054] In the manufacturing process of transformer coil assemblies, in order to meet the design requirements of transformers with different capacities and voltage levels, the conductors 11 used usually have a variety of different specifications. One of the most significant differences is that the width (or thickness) of the conductors 11 are different. After the coil is wound, the upper and lower end faces of the coil need to be pressed and fixed to prevent the conductors 11 from loosening. In the existing production equipment and processes, the clamping block 2122 is usually a fixed-size component designed for conductors 11 of a specific specification. When dealing with conductors 11 of different widths, it is necessary to replace the clamping block 2122 with a matching one in advance to achieve better clamping performance. Based on this, the adjustment frame 221 of the transformer coil assembly based on the axial clamping block linkage structure is provided with an auxiliary component 223. The length of the extension of several clamping blocks 2122 is adjusted by the cooperation of the auxiliary component 223 and the clamping block 2122 to adapt to conductors 11 of different widths.
[0055] Specifically, an auxiliary frame 2231 is rotatably connected inside the adjusting frame 221. Several push blocks 2232 are arranged along the circumferential direction on the auxiliary frame 2231 to engage with the pressing block 2122. (Three arc-shaped grooves of different heights are opened on the side of the push block 2232 near the pressing block 2122, and the side of the pressing block 2122 near the push block 2232 is shaped to match the arc-shaped grooves. Initially, the pressing block 2122 is located inside the central arc-shaped groove.) Before the winding of the wire 11, the innermost drive disc 32 is first restricted. The movement, according to the different widths of the guide wire 11, is driven by the tool to rotate the upper and lower rotating disks 2233 in sequence. During the rotation of the rotating disks 2233, the auxiliary frame 2231 is driven to rotate synchronously through several telescopic rods 2235 set on its lower end face. At this time, the position of the arc groove on the pushing block 2232 changes, and the arc grooves of different heights realize the adjustment of the position of the pressing block 2122 (either retracting or extending). The end face of the pressing block 2122 is provided with a waist-shaped groove 2123, and the inside of the waist-shaped groove 2123 is provided with a support rod 2124 and a top. The compression spring 2125 and the support block 2121 are located inside the waist-shaped groove 2123. The support rod 2124 slides through the support block 2121. One end of the compression spring 2125 is connected to the waist-shaped groove 2123, and the other end is connected to the support block 2121. When the position of the clamping block 2122 changes, the compression spring 2125 will be stretched or compressed. Then, the rotation of the rotating disk 2233 and the drive disk 32 is synchronously restricted. During this process, the winding of the wire 11 is completed. Then, the rotation restriction on the drive disk 32 is released, and the above steps are repeated to achieve the desired result. Finally, to prevent the rotating disk 2233 and the drive disk 32 from rotating during the transfer process, the locking frame 33 is placed inside the round hole 2234, the placement hole 121 and the limiting hole 321 (the locking frame 33 is divided into a connecting section and a locking section with a bottom fixed connecting screw. The connecting section and the locking section are rotatably connected. The corresponding screws in the round hole 2234, the placement hole 121 and the limiting hole 321 are all provided with threaded locking grooves. After the locking section is placed into the corresponding hole, the screw is rotated to achieve the locking work with the corresponding threaded locking groove).
[0056] It should be noted that the top of the auxiliary frame 2231 is connected to a rotating disk 2233 via several telescopic rods 2235 (in the initial state, the telescopic rods 2235 are in a compressed state). The rotating disk 2233 is rotatably connected to the end ring 12, and the end ring 12 is fixedly connected to the insulating cylinder 1. Therefore, when the auxiliary frame 2231, the adjusting frame 221 and the mounting plate 211 are moving, the telescopic rods 2235 gradually change from a compressed state to an extended state.
[0057] It is worth emphasizing that this transformer coil assembly based on the axial clamping block linkage structure has the following main advantages:
[0058] Firstly, in traditional coil manufacturing, winding, unwinding, transfer, and pressing are multiple separate processes. This design integrates the pressing process into the winding equipment. After the conductor 11 is wound on the support bar 14 of the insulating cylinder 1, the entire coil assembly does not need to be disassembled or moved from the winding machine. During the rotation of the drive disc 32, the adjusting cylinder 3 rotates. Through the transmission characteristics of its positive and negative threads, the upper and lower adjusting frames 221 move synchronously in opposite directions. The adjusting frames 221 drive all the pressing blocks 2122 to move axially through the connecting block 222 and the mounting plate 211 until they are evenly pressed on the upper and lower end faces of the coil. In this way, the large amount of auxiliary time spent on hoisting and transferring the coil in the traditional process is eliminated, the production cycle is greatly reduced, and the overall production efficiency is significantly improved. More importantly, it fundamentally eliminates the quality risks such as misalignment of the conductor 11, interlayer slippage, and even structural loosening caused by vibration and collision when the coil is transferred in an unfixed state. This lays a solid mechanical foundation for the stable progress of subsequent processes and the final quality of the transformer.
[0059] Secondly, in this embodiment, only a single-direction rotational driving force needs to be applied to the adjusting cylinder 3. The two sets of upper and lower threaded grooves 31 with opposite rotation directions on the adjusting cylinder 3 will synchronously drive the two sets of upper and lower adjusting frames 221 that mesh with them to make precise opposite linear movements along the axis. Since the mounting plate 211 is constrained by the sliding rod 142, it can only make axial translation. Therefore, the movement of the adjusting frame 221 is transmitted to all the clamping blocks 2122 on the mounting plate 211 without delay or deviation. Finally, all the clamping blocks 2122 distributed on the circumference of the coil end face will contact and clamp the wire 11 simultaneously in a completely synchronous and consistent manner. This synchronous and symmetrical clamping mechanism achieved by a single driving source ensures that the force applied to both ends of the coil is highly uniform and consistent, effectively avoiding problems such as local stress concentration, coil end face deformation, or inter-turn insulation damage caused by traditional methods.
[0060] Thirdly, the side of the clamping block 2122 that contacts the wire 11 is made of silicone rubber. This material has excellent elasticity and can produce slight deformation upon contact, thus perfectly adapting to the slight unevenness of the wire 11 surface, increasing the contact area, and dispersing the concentrated point pressure into uniform surface pressure. A compression spring 2111 is connected between the bottom end of the mounting plate 211 and the limiting groove 141 of the support bar 14. After the clamping block 2122 completes the clamping action, the stretched compression spring 2111 generates a continuous downward restoring force. This force is further transmitted to the clamping block 2122 through the mounting plate 211, forming an additional, constant clamping compensation. The elastic design of silicone rubber avoids damage to the insulation layer of the wire 11 caused by rigid contact. The introduction of the compression spring 2111 not only enhances the initial clamping force, but more importantly, it absorbs and disperses the stress caused by various mechanical vibrations and thermal expansion and contraction during the subsequent operation of the coil, thereby greatly improving the structural stability and reliability of the coil during operation.
[0061] Fourthly, to meet the production needs of conductors 11 with different widths, the structure is equipped with an adjustment system. Before winding, the rotating disk 2233 can be rotated by a tool according to the current conductor 11 specification. The rotating disk 2233 drives the auxiliary frame 2231 to rotate via the telescopic rod 2235. The push block 2232 on the auxiliary frame 2231 rotates accordingly. The push block 2232 is provided with arc-shaped grooves of different heights. By rotating, the arc-shaped grooves of different heights can be made to cooperate with the arc-shaped end of the clamping block 2122, thereby pushing the clamping block 2122 to slide along the internal support rod 2124. The device can precisely change its extension length relative to the mounting plate 211. After adjustment, the rotating disk 2233 is locked, and winding can begin. This design makes the clamping component 21 no longer a fixed-size special part. When facing wires 11 of different widths and specifications, there is no need to stop the machine to replace the entire set of clamping blocks 2122. Simple rotation adjustment can quickly complete the adaptation, which greatly improves the adaptability and production flexibility of the equipment. It can easily cope with small-batch, multi-variety production mode, reduce spare parts inventory and changeover time, and significantly reduce the overall production cost.
