Description

Technical Field

[0001] This utility model relates to the field of annealing technology for amorphous alloy three-dimensional coiled iron cores, and in particular to a monitoring model for annealing amorphous alloy three-dimensional coiled iron cores. Background Technology

[0002] Amorphous metals exhibit unique properties. Made from rapidly quenched liquid metals, the metal atoms arrange themselves in a random pattern, making this material easily magnetized. Amorphous alloy core transformers have lower losses, thus amorphous alloy distribution transformers have excellent application prospects. Currently, transformers on the market still use traditional power transformer manufacturing processes, with silicon steel sheets as the main magnetic material. However, silicon steel sheets suffer from low energy efficiency and high losses. Amorphous alloys are green and energy-saving high-tech materials; compared to traditional silicon steel sheets, they are more efficient, energy-saving, and environmentally friendly. Therefore, amorphous alloy transformers play a crucial role in power systems.

[0003] Transformers experience two main types of losses during operation: no-load loss and load loss. The load loss of a transformer is a variable loss, while the no-load loss includes both hysteresis loss and eddy current loss. The magnitude of the no-load loss is closely related to the transformer's core material, structure, and operating voltage. Adopting new equipment, technologies, and materials can reduce the no-load loss of transformers. Reducing losses is an effective method for energy conservation. Compared with traditional silicon steel distribution transformers, amorphous alloy transformers offer significantly better energy savings and have a very broad application prospect.

[0004] However, the annealing process of amorphous alloy cores has a significant impact on their losses. If the annealing temperature is too low, the disorder of the amorphous structure will be high, which will make it difficult for magnetic domain walls to move and result in greater hysteresis losses. If the temperature is too high, the amorphous alloy may crystallize, increasing defects such as grain boundaries, which will also increase hysteresis losses. A suitable temperature can allow atoms to obtain enough energy to relax, effectively release internal stress, optimize the magnetic domain structure, and thus reduce hysteresis losses and eddy current losses. If the annealing time is too short, the internal stress of the iron core will not have enough time to be fully released, and the magnetic domain structure will not be able to be fully adjusted to the optimal state, which will increase both hysteresis loss and eddy current loss, resulting in high overall loss. If the time is too long, it may cause excessive atomic diffusion, destroy the uniformity of the amorphous structure, and even induce slight crystallization, thus increasing the loss. However, for certain amorphous alloys with specific compositions, long-term annealing at appropriate temperatures may also exhibit stable low-loss performance. Only an appropriate annealing time can help to fully release internal stress, adjust the magnetic domain structure to the optimal state, and thus reduce loss. The holding time and cooling rate have a significant impact on the loss of the iron core. Therefore, it is necessary to monitor the loss of amorphous alloy iron cores online during the annealing process so as to adjust the temperature and holding time in a timely manner, in order to find the optimal annealing process parameters to reduce iron core loss, improve energy utilization efficiency during operation, reduce power waste, provide technical support for energy conservation and consumption reduction in the power system, and promote the power industry to develop towards a high-efficiency and green direction. Therefore, it is necessary to propose a three-dimensional coiled iron core annealing monitoring model for amorphous alloys. Summary of the Invention

[0045] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0046] To address this technical problem, this invention provides a three-dimensional annealing monitoring model for amorphous alloy coiled iron cores.

[0047] For details, please refer to Figures 1-16 An annealing monitoring model for an amorphous alloy three-dimensional wound iron core includes: a support, an amorphous alloy three-dimensional wound iron core 1, a high-voltage coil 2, a low-voltage coil 3, an insulating iron hoop 4, an AC frequency modulation power supply 32, a magnetizing busbar 10, and a power analyzer 51. The amorphous alloy three-dimensional wound iron core 1 is mounted on the support. Specifically, the support is welded together from a triangular support plate 5, a horizontal plate 6, a vertical plate 7, and a base plate 8. The high-voltage coil 2 and the low-voltage coil 3 are mounted on the upper yoke of the amorphous alloy three-dimensional wound iron core 1.

[0048] The insulating iron hoop 4 is used to fix the amorphous alloy three-dimensional coiled iron core 1; the magnetized busbar 10 is supported by the insulating support plate 9 and placed in the inner frame of the amorphous alloy three-dimensional coiled iron core 1, and the bottom of the insulating support plate 9 is set on the bottom plate of the annealing furnace 26; the AC frequency modulation power supply 32 is electrically connected to the high voltage coil 2 and the AC frequency modulation power supply 32 is electrically connected to the power grid; the voltage clamp and the current clamp are electrically connected to the low voltage coil 3 respectively.

[0049] The power analyzer 51 is electrically connected to the voltage clamp and current clamp, and is used to receive signals from the voltage clamp and current clamp and calculate the core loss. This design presents an annealing monitoring model for amorphous alloy three-dimensional coiled iron cores, which can acquire loss data in real time during the annealing process. This allows operators to immediately grasp the loss status of the amorphous alloy three-dimensional coiled iron core 1. If an abnormal increase in loss or other abnormal conditions occur, measures can be quickly taken to adjust the situation, preventing further deterioration and avoiding damage to core performance or equipment failure due to prolonged abnormalities. Simultaneously, through online monitoring data, annealing process parameters, such as temperature and time, can be optimized in a timely manner based on real-time feedback, ensuring the annealing process reaches its optimal state. This results in more stable and superior performance of the amorphous alloy three-dimensional coiled iron core 1, thereby improving product consistency and reliability, and ultimately reducing the defect rate.

[0050] This utility model embodiment has multiple insulating iron hoops 4, each including an iron ring 15, a left half lock 21, a right half lock 23, and an insulating horizontal plate 19. The left half lock 21 and the right half lock 23 are located at opposite ends of the iron ring 15, and the insulating horizontal plate 19 is located outside the left half lock 21 and the right half lock 23. The left half lock 21, the right half lock 23, and the insulating horizontal plate 19 are fixedly connected by a screw a17 and a nut a18. A predetermined distance is provided between the iron rings 15 of each insulating iron hoop 4. In order to prevent the high and low voltage coils of the upper yoke of the amorphous alloy three-dimensional coiled iron core 1 from short-circuiting during the annealing process, the inside of the lock is insulated. An insulating sleeve 22 is provided in the internal cavity of the left half lock 21 and the right half lock 23 so that the iron rings 15 of adjacent insulating iron hoops 4 are in a non-contact state.

[0051] Specifically, the iron ring 15 is composed of two semi-circular structures with connecting plates, connected by bolts 14. The iron ring 15 is provided with two connecting parts 20 for installing the left half lock 21 and the right half lock 23.

[0052] In this embodiment of the utility model, multiple magnetized busbars 10 are provided, and two adjacent magnetized busbars 10 are fixed by screws b24 and nuts b25.

[0053] In this embodiment of the invention, the high-voltage coil 2 is fixed to the upper yoke of the amorphous alloy three-dimensional coiled iron core 1 by means of a busbar 12 and screws 13, and the input and output terminals of the high-voltage coil 2 are respectively connected to the terminals of the AC frequency modulation power supply 32.

[0054] The output terminal of the low-voltage coil 3 in this embodiment of the invention is connected to a current clamp and a voltage clamp, respectively, and the voltage clamp and the current clamp are respectively connected to different channels of the power analyzer 51.

[0055] The amorphous alloy three-dimensional coiled iron core 1 of this utility model embodiment includes multiple single-frame iron cores 28, and the multiple single-frame iron cores 28 are separated by insulating vertical plates 27. Specifically, when monitoring the loss, an insulating vertical plate 27 is placed between every two single-frame amorphous alloy three-dimensional coiled iron cores 28 so that there is no contact between every two single-frame amorphous alloy three-dimensional coiled iron cores 28, and adjacent two single-frame iron cores 28 are fixed by insulating iron hoops 4.

[0056] In the annealing monitoring model of the amorphous alloy three-dimensional wound iron core of this utility model embodiment, during the annealing process, the power analyzer 51 can control the magnetic busbar 10 to magnetize the amorphous alloy three-dimensional wound iron core 1. When the monitored loss and magnetic characteristic data exceed the preset range, the power analyzer 51 can adjust the output frequency and voltage of the AC frequency modulation power supply 32; specifically, as shown in the figure... Figure 2 The model shown is placed in the annealing furnace 26, and the top of the annealing furnace 26 has a small hole for the high-temperature resistant wire 11 to pass through. The model of the annealing furnace 26 is shown in the figure. Figure 13 As shown; when monitoring losses, the input and output terminals of the high and low voltage coils need to be connected to the AC frequency modulation power supply 32 and the power analyzer 51, specifically, as follows: Figure 14 , 15 As shown in the diagram; then, connect the low-voltage coil A input interface 36 to voltage clamp a42, the low-voltage coil B input interface 38 to voltage clamp b44, and the low-voltage coil C input interface 40 to voltage clamp c45. Connect the low-voltage coil D output interface 37 to voltage clamp d46, the low-voltage coil E output interface 39 to voltage clamp e48, and the low-voltage coil F output interface 41 to voltage clamp f47; connect the high-voltage coil A output interface 33, the high-voltage coil B output interface 34, and the high-voltage coil C output interface 35 to the corresponding channels of the AC frequency modulation power supply 32.

[0057] like Figure 16 As shown, connect the low-voltage coil D output interface 37 to current clamp a43, the low-voltage coil E output interface 39 to current clamp b49, and the low-voltage coil F output interface 41 to current clamp c50. Connect voltage clamps a42, b44, c45, d46, f47, and e48 to the corresponding interfaces on the power analyzer 51. Connect current clamps a43, b49, and c50 to the corresponding interfaces on the power analyzer 51.

[0058] The annealing process mainly consists of three steps: heating, holding, and cooling. Throughout the process, current is supplied to the high-voltage coil 2 wound around the upper yoke of the amorphous alloy three-dimensional coiled iron core 1 via an AC voltage regulator 32, inducing voltage and current on the low-voltage side. The power analyzer 51 is used to observe the losses and voltage / current waveforms of the amorphous alloy three-dimensional coiled iron core 1, thus obtaining its state in the annealing furnace 26. This allows operators to immediately grasp the core's losses and magnetic properties. In the annealing process of the amorphous alloy three-dimensional coiled iron core 1, temperature and time control are crucial for performance optimization. When the annealing process exceeds the optimal annealing temperature, the unit no-load loss of the iron core increases significantly with the continuous rise in temperature and the extension of time. To address this characteristic, a dynamic control mechanism needs to be established: during the heating process, if the loss value is monitored to exceed 5% of the rated value, the temperature of the annealing furnace 26 should be immediately reduced to bring the loss back to a reasonable range. During the cooling phase, while a faster cooling rate helps reduce no-load loss, it increases the excitation power. Therefore, continuous monitoring of the core loss is necessary; once the value exceeds 5% of the rated value, the cooling rate should be adjusted promptly to achieve a balance between the two indicators. After the amorphous alloy three-dimensional coiled core 1 reaches the optimal annealing temperature, the heat preservation stage is equally important. Due to the extremely slow relaxation phenomenon within the strip's internal structure, properly controlling the heat preservation time is crucial for reducing the core's excitation power. In practice, continuous monitoring of the core loss value is necessary to scientifically determine the heat preservation time, effectively avoiding the degradation of the core's energy-saving performance caused by improper heat preservation time, and ensuring that the performance of the amorphous three-dimensional coiled core reaches its optimal state.

[0059] This design, on the one hand, can promptly detect anomalies, preventing the scrapping or rework of the amorphous alloy three-dimensional coiled core 1 due to improper annealing, reducing waste of raw materials and energy, and lowering production costs. On the other hand, it can effectively monitor and provide early warnings of potential faults, allowing for reasonable maintenance planning and avoiding losses from unplanned downtime, thus reducing maintenance costs. Furthermore, this design can reduce the time and workload of regular manual inspections through online monitoring, while avoiding production delays caused by untimely or inaccurate manual inspections. In addition, optimizing the process based on monitoring data can make the annealing process more efficient, shorten the production cycle, and improve overall production efficiency. Finally, the amorphous alloy three-dimensional coiled core annealing monitoring model of this design can accumulate a large amount of loss data during the annealing process. In-depth analysis of this data can uncover loss variation patterns and their relationship with process parameters, providing strong data support for process improvement and product development. This contributes to the continuous development of amorphous alloy three-dimensional coiled core technology. As the manufacturing industry moves towards intelligence and digitalization, online monitoring technology is an important means to achieve intelligent monitoring and management of the production process. The use of online monitoring of losses during the annealing process of amorphous alloy three-dimensional coiled iron core helps enterprises improve their level of intelligence, adapt to the major trends in industry development, and enhance their market competitiveness.
