[0031] In the field of power transformer manufacturing, the core is the core component of the transformer, and its performance and quality directly affect the overall efficiency and operational stability of the transformer. Traditional cores are mostly made of crystalline alloy materials and assembled into core structures by stacking or welding. However, this traditional method has many shortcomings, such as large core loss, high noise, high processing complexity and difficult cost control. In particular, with the continuous growth of electricity demand and the improvement of energy efficiency requirements, traditional core materials and their assembly processes have been unable to meet the needs of modern transformers for high efficiency, low noise, compactness and environmental protection.

[0032] As a new type of material, amorphous alloys have gradually become an ideal choice to replace traditional crystalline alloy cores with their excellent electromagnetic properties (such as low iron loss, high magnetic permeability) and good processing plasticity. Amorphous alloy cores can not only significantly improve the energy efficiency of transformers, but also effectively reduce operating noise, and are an important direction for the technical upgrading of power transformers. However, in the process of processing amorphous alloys into cores, due to their unique physical properties and high sensitivity to heat treatment, their assembly method becomes a key technical problem.

[0033] Traditional amorphous alloy core assembly often adopts a flat stacking method, which not only limits the space utilization of the core, but also may lead to uneven magnetic circuits, affecting transformer performance. In addition, since amorphous alloys are prone to softening and deformation at high temperatures, how to achieve accurate and efficient assembly while ensuring material performance has become an urgent problem to be solved.

[0034] In view of this, the assembly method and system of the amorphous alloy three-dimensional wound core provided in the embodiment of the present application first obtains a plurality of core single frames; then limits the position of these core single frames, and ensures that each core single frame remains stable in a suspended state. This step effectively avoids the misalignment and deformation in the initial assembly; then adjusts the core single frame to a preset position, and anneals the core single frame to optimize its physical properties and reduce residual stress; after the annealing is completed, the core single frame is cooled and shaped to ensure that each core single frame reaches the target shape and target size; then the shaped multiple core single frames are assembled and insulated to obtain a high-performance three-dimensional wound core. The embodiment of the present application proposes a practical solution to the common material deformation control problems, assembly accuracy improvement challenges and overall performance optimization requirements in the assembly process of amorphous alloy cores, which can significantly improve the assembly efficiency and finished product quality of amorphous alloy cores while ensuring material properties.

[0035] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0036] See also Figure 1 , Figure 1 The flowchart of the assembly method of the amorphous alloy three-dimensional wound core provided in the embodiment of the present application includes but is not limited to steps 110 to 150.

[0037] Step 110: Obtain multiple core single frames;

[0038] Step 120: Limit the core single frame and put the core single frame in a hanging state;

[0039] Step 130: adjusting the core single frame to a preset position and performing annealing treatment on the core single frame;

[0040] Step 140: Cooling the annealed core single frame and performing shaping treatment on the core single frame;

[0041] Step 150: Assemble and insulate the multiple shaped core single frames to obtain a three-dimensional wound core.

[0042] Steps 110 to 150 are described in detail below.

[0043] In one embodiment, the single-frame core refers to a transformer core having a single frame structure. According to different applications and requirements, the single-frame core can be further subdivided into multiple types, such as a single-phase frame core and a single-frame part in a three-phase four-frame core.

[0044] In one embodiment, the core single frame can adopt a more compact shape such as a semicircle, and this design greatly reduces the cross-sectional area of ​​the core as a whole to half of the original. Not only does it optimize the structure of the core, but it also greatly accelerates the efficiency of heat transfer inside the core, ensuring that the heat can be quickly and evenly distributed throughout the core material. Therefore, the time required for annealing is significantly shortened, the annealing efficiency is significantly improved, and at the same time, due to the shortening of the annealing cycle, the energy consumption and cost during the annealing process are also greatly reduced accordingly. In addition, due to the reduction in the cross-sectional area of ​​the core single frame, the temperature gradient between the inside and the surface of the core will also be reduced accordingly. It is worth noting that during the annealing process, the temperature gradient is one of the main factors that cause the difference between the internal and surface annealing curves (i.e., the curve of temperature changes over time), and the smaller cross-sectional area helps to reduce this difference, making the annealing process more consistent between the inside and the surface of the core. In addition, annealing is not only a process to improve the physical properties of the material, but also a key step in releasing the internal stress of the material. When annealing is performed in a suspended state, the more uniform temperature distribution caused by the reduction in cross section helps to release stress more evenly throughout the core. This helps reduce problems such as local deformation or cracks caused by stress concentration, thereby improving the overall performance and reliability of the core. Due to the enhanced uniformity of the annealing process, the physical properties of each part of the core after annealing (such as magnetic permeability, etc.) will be more consistent. This helps ensure that the performance of each part matches each other during the operation of the transformer, thereby improving the overall performance and efficiency of the transformer.

[0045] In one embodiment, after obtaining the core single frame, it is limited and placed in a suspended state. This processing method not only ensures the stability of the core in the subsequent processing process, but also provides it with free space to release internal stress. Especially during the annealing process, the suspended state can maximize the release of stress, thereby significantly improving the product's noise control ability and reducing no-load losses, laying a solid foundation for the efficient and stable operation of the transformer.

[0046] In one embodiment, after the core single frame is adjusted to a preset position, it is annealed to improve its physical properties. During the annealing process, the core single frame is precisely controlled to achieve an ideal organizational structure, reduce its internal stress and improve its magnetic permeability. At the same time, since the core has been placed in a suspended state before, this treatment process can be carried out more evenly and effectively, ensuring the overall improvement of the core performance.

[0047] In one embodiment, after annealing, the core is rapidly cooled to fix its structure. Then, it is shaped to eliminate possible minor deformation or unevenness. This process is performed separately (i.e., each core is shaped separately before assembly) not only simplifies the operation process but also improves the shaping effect to ensure that each core can achieve the best shape and size accuracy.

[0048] Exemplarily, the shaping process of the core single frame can combine the methods of tapping correction and mold precision limiting. Specifically, the tapping technology uses delicate tapping movements to fine-tune specific areas of the core single frame to eliminate minor deformations or unevenness. The mold precision limiting uses the precise shape of the customized mold to firmly place the core single frame in it, and further adjusts and fixes its shape through physical limiting to ensure that each core single frame can reach the ideal state. The combined use of these two methods not only improves the efficiency of shaping, but also ensures the accuracy and consistency of the shaping results.

[0049] In one embodiment, all the carefully processed core single frames are finally assembled into a complete three-dimensional wound core. During the assembly process, precise adjustments are made according to the design requirements to ensure the close fit between the components and the uniform distribution of the magnetic circuit. After the assembly is completed, insulation treatment is performed to improve the safety and reliability of the product. At this point, a high-performance amorphous alloy three-dimensional wound core is successfully manufactured and is ready for use.

[0050] In one embodiment, after the precise assembly of multiple core single frames is completed to construct a complete three-dimensional wound core, during the insulation treatment of the three-dimensional wound core, an insulating coating can be evenly applied to each surface of the three-dimensional wound core to form a uniform, dense and durable insulating layer. Subsequently, in order to ensure that the insulating layer can fully exert its insulating efficiency and firmly adhere to the core, it can be naturally dried. Through precise temperature control and time control, the insulating layer can be uniformly and fully cured, thereby effectively improving the overall insulation performance of the three-dimensional wound core, laying the foundation for the safe and efficient operation of the transformer.

[0051] In one embodiment, the insulation treatment process of the three-dimensional wound core can be a comprehensive method of applying resin paint, tightly winding insulating tape, and reinforcing with cable ties. Specifically, first, by evenly applying resin paint, a strong and durable insulating layer is formed on the surface of the core to effectively isolate electrical conduction. Subsequently, the insulating tape is tightly wound on the resin paint layer, which not only enhances the thickness and strength of the insulating layer, but also provides additional mechanical protection. Finally, the tape is firmly tied with a cable tie to ensure the integrity and stability of the insulating layer structure to prevent loosening or damage during subsequent processing or transportation.

[0052] In one embodiment, in step 120, in order to ensure the stability and accuracy of the core single frame in the subsequent processing, before the core single frame is annealed, a limiting frame matching its size can be configured on the outside of each core single frame. This design not only effectively limits the displacement of the core single frame, but also provides an additional protective barrier for it. In addition, a variety of fixing methods can be used, including but not limited to using solid steel plates for close fitting and reinforcement, and using cable ties to firmly tighten the core frame. The comprehensive use of these measures ensures the absolute stability of the core single frame during annealing and subsequent operations, laying a solid foundation for improving processing accuracy and ensuring the quality of finished products.

[0053] In one embodiment, during the annealing process of the core single frame, the core single frame is energized and magnetized, and the selected current intensity is not less than 1000 amperes to ensure sufficient penetration and stability of the magnetic field. It is worth noting that during the annealing process, the core single frame is magnetized and the consistency of the magnetic flux direction is maintained, which effectively avoids magnetic interference from other core frames. This technical measure significantly improves the annealing environment of the core, making the annealing effect more ideal, and the physical and magnetic properties of the core are significantly improved.

[0054] In one embodiment, once the core single frame reaches the preset annealing temperature, the insulation program can be started to ensure that the core fully reacts in a stable high temperature environment. The insulation temperature is set at no less than 300°C to fully meet the annealing requirements of the amorphous alloy material. At the same time, the insulation time is also strictly controlled to no less than 60 minutes to ensure the adequacy and thoroughness of the annealing process.

[0055] In one embodiment, a protective gas (such as nitrogen) is introduced during the annealing process to prevent the core single frame from being oxidized by oxygen in the air at high temperature. Specifically, at the beginning of the annealing process, nitrogen is filled into the annealing furnace to exhaust the air in the furnace, and is continuously introduced throughout the annealing process until the annealing process is completed.

[0056] In one embodiment, in order to achieve cooling of the core single frame, a specific cooling program can be started. This program may include turning on cooling equipment (such as fans, cooling water systems, etc.) and adjusting cooling parameters (such as cooling rate, cooling time, etc.) to ensure that the core single frame can be cooled in a predetermined manner. When the temperature of the core single frame drops to 150°C or below, it can be taken out of the annealing device. This cooling process not only ensures that the core single frame is cooled quickly and evenly within a suitable temperature range, but also effectively avoids thermal stress or deformation problems that may be caused by excessive temperature differences. By accurately controlling the cooling rate, the annealing effect can be further consolidated, laying a good foundation for subsequent shaping treatment.

[0057] In one embodiment, when the core single frame is shaped, a high-precision shaping mold can be used to accurately apply pressure to the core single frame. Through the precise design and adjustment of the mold, the uniform distribution of the pressure is ensured, thereby guiding the core to gradually reach the preset target shape and target size. This process not only improves the appearance quality of the core, but also ensures its precise matching in subsequent assembly.

[0058] See also Figure 2 , Figure 2 2 is an overall structural diagram of an assembly system for an amorphous alloy three-dimensional wound core provided in an embodiment of the present application. The assembly system can be applied to the above assembly method. The system includes an annealing device 210. The annealing device 210 has an annealing fixture 220 built in. Figures 3 to 5 As shown, the annealing fixture 220 includes an annealing frame 310, a support member 320 and a limit member 330. The annealing frame 310 is composed of a plurality of bottom beams, columns and cross beams, which are staggered and tightly spliced ​​to jointly construct a stable and open cavity space, providing an ideal working environment for the annealing treatment of the core single frame 300. The support member 320 can steadily suspend the core single frame 300 to be treated in the open cavity of the annealing frame 310, which not only ensures the smooth progress of the annealing process, but also facilitates the effective transfer and diffusion of heat. The limit member 330 is arranged in the open cavity to accurately limit and fix the position of the core single frame 300, effectively preventing the displacement or deformation that may occur during the annealing process, and ensuring the uniformity and consistency of the annealing effect. In addition, Figure 3 In the embodiment, the annealing device 210 also has a built-in limiting frame 340, which further improves the functionality and flexibility of the system. The limiting frame 340 can closely fit the outline of the core single frame 300, strictly limit and adjust its shape, and ensure that the shape of the core is always maintained in the best state during annealing and subsequent processing.

[0059] In one embodiment, there are several support members 320, which pass through the windows inside the core single frame 300 to achieve a stable connection and fixation with the annealing frame 310. This design not only ensures the stable suspension of the core single frame 300 during the annealing process, avoiding the problem of uneven treatment caused by shaking or displacement, but also enables heat to be more evenly transferred to various parts of the core single frame 300, thereby improving the consistency and reliability of the annealing effect. At the same time, the distribution of multiple support members 320 also takes into account the structural characteristics and weight distribution of the core single frame 300, ensuring the smooth progress of the entire annealing process.

[0060] In one embodiment, these limiters 330 take full account of the geometric features and processing requirements of the core single frame 300, and can flexibly limit the bottom, side or top of the core single frame 300. Specifically, for the bottom of the core single frame 300, the limiter 330 provides stable support and positioning, effectively preventing the core single frame 300 from sinking or shifting during the annealing process. For the side, the limiter 330 ensures the stability of the core single frame 300 in the horizontal direction through precise fitting and restriction, and avoids the occurrence of tilting or distortion. For the upper part, the limiter 330 also plays a key role. They not only limit the upward movement of the core single frame 300, but also help maintain the overall shape and dimensional accuracy of the core single frame 300. This all-round, multi-angle limit design allows the core single frame 300 to always maintain an ideal posture and position during the annealing process, thereby ensuring the uniformity and consistency of the annealing effect. At the same time, this design also improves processing efficiency and finished product quality, laying a solid foundation for subsequent assembly and application.

[0061] In one embodiment, when a limiting frame 340 matching the outer dimensions of the core single frame 300 is disposed on the outer side of the core single frame 300, the core single frame 300 can be further fixed with fixing parts to minimize the impact on the intrinsic performance of the core while ensuring stability during the annealing process. Compared with the traditional annealing method in which a large number of fixing parts are used to tightly fit together three core single frames 300, this embodiment significantly reduces the force on the core single frame 300, avoids stress concentration caused by excessive restraint, and thus reduces the possible adverse effects on the core noise and no-load loss performance. Figure 3 and Figure 5 As shown, the cable tie 10 can fit the core single frame 300 tightly but not excessively, thereby achieving effective fixation. At the same time, a stronger fixing member such as a steel plate 20 can also be selected according to specific needs to provide additional support and stability.

[0062] In one embodiment, if Figure 5 As shown, two core components, a magnetizing component 350 and a temperature measuring component, are added to the annealing device 210. The magnetizing component 350 can be inserted into the inner window of the core single frame 300, and by using high-quality conductive materials such as copper or aluminum, it ensures that the current can flow smoothly and generate the required magnetic field effect. These conductors are not only made of excellent materials, but also carefully wound around the core to form a multi-turn structure, thereby achieving precise control and enhancement of the magnetic properties of the core. At the same time, the temperature measuring component can monitor and record the temperature changes during the annealing process in real time and accurately, which not only improves the accuracy and controllability of the annealing process, but also ensures that the core can always remain in the optimal temperature range during the annealing process, further improving the quality and performance of the product.

[0063] In one embodiment, when the annealing device 210 is turned on, a non-oxidizing and stable heat treatment environment can be created by evacuating the inside of the device to a vacuum state and then filling it with pure nitrogen. Then, the power is turned on for heating, and the heat is evenly transferred in the nitrogen atmosphere to prepare for the subsequent annealing treatment. It is worth noting that by activating the magnetizing component 350 to perform a deep magnetization treatment on the core single frame 300, this process not only enhances the magnetic properties of the core, but also lays a solid foundation for its subsequent application. Among them, the magnetizing current is not less than 1000 amperes. As the temperature inside the annealing device 210 and the core single frame 300 gradually rises, the temperature is accurately controlled to a predetermined annealing temperature. After reaching this critical temperature point, the insulation stage is entered, and the insulation temperature is set within a range of not less than 300°C to ensure that the core single frame 300 can be fully and evenly heated. At the same time, the insulation time is also accurately controlled to not less than 60 minutes to ensure the full realization and stability of the annealing effect.

[0064] In one embodiment, the assembly system further includes a shaping mold for applying pressure to the core single frame 300 so that the core single frame 300 reaches a target shape and a target size. Specifically, in the process of shaping the core single frame 300, the shaping mold can ensure uniform distribution and precise control of the pressure applied to the core single frame 300, thereby avoiding deformation or damage of the core single frame 300 due to uneven force, and ensuring the quality and effect of shaping.

[0065] Furthermore, when multiple annealed and shaped core single frames 300 are ready, they can be assembled together using an assembly process, and then insulated to ensure the electrical safety and stability of the entire structure. Figure 6 The three-dimensional wound core 600 is shown.
