[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs.

[0026] With the continuous advancement of amorphous alloy three-dimensional wound core transformer technology, this type of transformer has been widely used in various power fields with voltage levels of 35kV and below. With many advantages such as three-phase balance, material saving, low no-load loss, small no-load current, strong short-circuit resistance, low noise level and low electric and magnetic field intensity, they have become one of the mainstream products in the transformer industry.

[0027] As the core magnetic circuit component of the transformer, the performance of the transformer core is crucial. However, the inherent characteristics of amorphous alloy strips, such as narrow width, difficult processing, fragility, and high sensitivity to mechanical stress, limit the widespread application of three-dimensional wound core technology in transformers with voltage levels above 35kV. Although some manufacturers have tried to manufacture high-voltage, large-capacity cores by winding multiple amorphous alloy strips, this method is still restricted by multiple factors such as the defects of amorphous alloy strips themselves, complex winding processes, and high assembly process precision requirements. These factors often result in the performance of the core failing to meet the established standard requirements, further limiting the application of amorphous alloy three-dimensional wound core transformers in a wider range of fields.

[0028] In view of this, an embodiment of the present application provides a method for processing and assembling an amorphous alloy three-dimensional rolled core. First, an amorphous alloy straight strip is obtained, and the straight strip is processed according to the preset single-piece strip width of the core single frame to obtain a target strip. This step effectively avoids the waste problem caused by the width limitation of the material, and at the same time simplifies the processing flow and significantly improves the overall processing efficiency. Then, the target strip is respectively wound on multiple core inner molds to form multiple core single frames. Subsequently, multiple core single frames are assembled, for example, three core single frames are assembled in pairs to obtain a three-dimensional rolled core. This process is conducive to solving the problems of difficulty and fragility in processing amorphous alloy strips. Then, the three-dimensional rolled core is further processed and split to obtain multiple processed semi-processed core single frames. Next, an outer mold insulating plate is set on the semi-processed core single frame, and an outer core mold is further set on the outer mold insulating plate, thereby obtaining a target core single frame. This step can not only enhance the structural strength of the core, but also greatly improve its electrical insulation performance, so that it can easily cope with the needs of higher voltage levels and large capacity. Finally, an inter-frame insulating plate is set on the target core single frame, and assembled to obtain a target three-dimensional coiled core. In summary, this embodiment effectively overcomes the technical difficulties in the manufacture and application of amorphous alloy three-dimensional coiled cores through innovative processing and assembly methods, and improves the production efficiency and performance of the core.

[0029] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0030] See also Figure 1 , Figure 1 This is a flow chart of a method for processing and assembling an amorphous alloy three-dimensional wound core provided by an embodiment of the present application. The process may include but is not limited to steps 110 to 150.

[0031] Step 110: Obtain an amorphous alloy straight strip, and process the straight strip according to a preset single-piece strip width of a single core frame to obtain a target strip;

[0032] Step 120: Winding the target material strip onto a plurality of core inner molds to obtain a plurality of core single frames, and assembling the plurality of core single frames to obtain a three-dimensional rolled core;

[0033] Step 130: Processing and splitting the three-dimensional coiled iron core to obtain a plurality of processed semi-processed iron core single frames;

[0034] Step 140: setting an outer mold insulating plate on the semi-processed core single frame, and setting a core outer mold on the outer mold insulating plate to obtain a target core single frame;

[0035] Step 150: After setting inter-frame insulating plates on the target core single frame, assemble them to obtain the target three-dimensional coiled core.

[0036] In one embodiment, the amorphous alloy straight strip is an alloy material with special properties, which can usually be prepared by a method of rapidly cooling a liquid alloy. This method can disrupt the regular arrangement of atoms in the metal material to form a solid metal material with a disordered atomic arrangement, i.e., an amorphous metal material. The amorphous alloy straight strip has excellent magnetic properties, corrosion resistance, wear resistance, high strength, hardness, and other properties.

[0037] In one embodiment, after obtaining the amorphous alloy straight strip, the straight strip can be further customized according to the preset core single frame single piece strip width to produce a target strip that meets the requirements. The following is a specific processing flow example, with Figure 2 To explain in detail: When the width of the straight material strip 210 is greater than the preset width of the single-piece material strip, the curve processing technology (a technology that transforms the originally straight material into a shape with a specific curvature through a bending or shaping process) can be used to shape the straight material strip into a first curved material strip 220. This first curved material strip can directly meet the requirements of the target material strip. On the contrary, when the width of the straight material strip 210 is less than the preset width of the single-piece material strip, it is first processed into a second curved material strip 230 using the curve processing technology, and then a straight material strip with an appropriate width is selected from these straight material strips as the target straight material strip, and then the second curved material strip is combined with the target straight material strip 240 to ensure that the total width of the second curved material and the target straight material strip is consistent with the preset width of the single-piece material strip, thereby forming the required target material strip.

[0038] In one embodiment, after the target strip is obtained by processing, the cut target strip can be further trimmed to remove burrs and uneven parts to ensure that it meets the required size and shape. Furthermore, the processed target strip can be inspected to ensure that its size, shape and performance meet the requirements. It is worth noting that during the processing, care should be taken to protect the surface of the amorphous alloy straight strip to avoid scratches or contamination.

[0039] In one embodiment, the core inner mold generally refers to an internal mold used in the core manufacturing or processing process. This mold plays a key role in the core manufacturing and is used to ensure that the shape, size and performance of the core meet the design requirements. There are various types of core inner molds, and different types of inner molds can be selected according to the shape, size and manufacturing requirements of the core. Some common types of core inner molds include: Integral inner mold: This inner mold is a complete integral structure, which is suitable for the manufacture of cores with simple shapes and small sizes. Combined inner mold: It is composed of multiple components and is suitable for the manufacture of cores with complex shapes and large sizes. The combined inner mold can be easily disassembled and assembled, which is convenient for the maintenance and replacement of the mold. Adjustable inner mold: It has an adjustable structure and can be adjusted according to the different sizes of the core. This inner mold improves the versatility and flexibility of the mold.

[0040] In one embodiment, the core inner mold can be obtained by the following method: obtaining the inner mold material; according to the preset inner frame size of the core single frame, processing the inner mold material to obtain the core inner mold. Among them, the selection of the inner mold material depends on the manufacturing requirements of the core, the working environment and the expected life. Common inner mold materials include high-strength steel, alloy steel, hard alloy, etc. These materials have the characteristics of high strength, high hardness, good wear resistance, etc., and can meet the use requirements of the core inner mold. After obtaining the inner mold material, some pretreatments such as cutting, cleaning, deburring, etc. can be performed first to ensure that the surface of the material is flat and defect-free, providing a good foundation for subsequent processing. Then, according to the inner frame size and shape of the core single frame, the structure of the inner mold is designed. This includes determining the parameters such as the wall thickness, shape, and size of the inner mold to ensure that the inner mold can be closely matched with the core single frame while meeting various requirements in the manufacturing process. Use appropriate processing methods and processes to process the inner mold material. This may include turning, milling, grinding, wire cutting and other processing methods. During the processing, the processing accuracy and surface quality need to be strictly controlled to ensure that the shape and size of the inner mold are consistent with the preset requirements.

[0041] In one embodiment, after the processing is completed, the inner mold can be further inspected and tested. This includes size inspection, shape inspection, surface quality inspection and necessary performance tests (such as hardness test, wear resistance test, etc.). Through inspection and testing, it can be ensured that the inner mold meets the design requirements and use requirements, providing reliable guarantee for subsequent core manufacturing.

[0042] In one embodiment, if Figure 3As shown, after the core inner mold 310 is successfully prepared, the core inner mold can be fixed on the core winding machine 320, and then the pre-prepared target material strip 330 is wound on these core inner molds to obtain multiple core single frames. It is worth noting that each of these wound core single frames presents an angle design of 60°, which enables them to be assembled into a triangular structure with a total internal angle of 180°. Such a design not only optimizes the structural layout of the core, but also enhances its overall stability and mechanical strength.

[0043] In one embodiment, when the target material strip is wound onto multiple core inner molds, the operation can be flexibly performed based on the comparison between the width of the straight material strip and the width of the monolithic material strip. Specifically, if the width of the straight material strip is less than the width of the monolithic material strip, it can be positioned to the portion of the straight material strip that is insufficient in width, i.e., the first position. Subsequently, at the first position, a side-by-side winding method is adopted, and two or more material strips (for example, a second curved material strip that has been processed by curves and a target straight material strip) are used to make up the width to ensure that they can form a complete core single frame after being wound together on the core inner mold. On the other hand, if the width of the straight material strip is greater than the width of the monolithic material strip, then only one first curved material strip that has been processed by appropriate curves can be selected and directly wound on the core inner mold to obtain a core single frame that meets the requirements. Such an operation method not only improves the utilization rate of the material strip, but also ensures the manufacturing accuracy and consistency of the core single frame.

[0044] In one embodiment, these core single frames are assembled to construct a three-dimensional wound core. Then, the three-dimensional wound core is subjected to a series of necessary processing, such as annealing to improve its flexibility and stability, or magnetization to meet specific magnetic requirements. After completing these processing steps, the three-dimensional wound core can be disassembled and processed to finally obtain multiple processed semi-processed core single frames.

[0045] In one embodiment, the processing flow of the core outer mold is as follows: first, select a suitable outer mold material; then, according to the specific shape and size of the iron yoke in the semi-processed core single frame, accurately process the upper outer mold and the lower outer mold; then, according to the height of the semi-processed core single frame and the cross-sectional size of the core column, process the outer mold material to obtain the side outer mold. Finally, the upper outer mold, the lower outer mold and the side outer mold are combined to form a complete core outer mold.

[0046] In one embodiment, the processing steps of the outer mold insulation board are as follows: first, prepare suitable insulation materials; then, cut or process the insulation materials according to the size of the upper outer mold to make the upper outer mold insulation board; similarly, according to the size of the lower outer mold, process the lower outer mold insulation board; and then, according to the size of the side outer mold, customize and process the side outer mold insulation board. Finally, the upper outer mold insulation board, the lower outer mold insulation board and the side outer mold insulation board together constitute the outer mold insulation board.

[0047] See also Figure 4 and Figure 5 , when an outer mold insulating plate is set on the semi-processed core single frame, and the core outer mold is further installed on the insulating plate to form the target core single frame, the following preset sequence can be followed: first, the upper outer mold insulating plate 410, the lower outer mold insulating plate 420 and the side outer mold insulating plate 430 are fixed on the outside of the core single frame; then, the upper and lower outer molds 510, the side outer mold 520 are installed in sequence according to the preset sequence, and finally the upper outer mold 530 is installed. During the entire installation process, it is necessary to ensure that the upper outer mold, the lower outer mold and the side outer mold are firmly fixed to ensure the stability of the structure. It should be noted that the core outer mold plays the role of a skeleton here, which tightly wraps the core single frame together to form a solid whole. This helps to reduce the adverse effects that the material properties of the amorphous alloy strip and its deadweight may have on the core performance. By setting an outer mold insulating plate between the core outer mold and the core single frame, it can be ensured that the insulation performance between the core single frames can meet the established requirements. Through such insulation treatment, multiple point connections in the core can be effectively prevented, thereby further ensuring that the performance of the core is not affected.

[0048] In one embodiment, if Figure 6 As shown, when setting the inter-frame insulating plates on the target core single frame, a first inter-frame insulating plate 620 can be set on the side 610 of the core column of the target core single frame and a second inter-frame insulating plate 630 can be set on the side outer mold, respectively, to ensure that when multiple target core single frames are spliced ​​together, the insulation performance between them can meet the established standards and requirements.

[0049] It should be noted that this embodiment does not impose a rigid regulation on the specific order of installing the outer mold insulation plate and the core outer mold on the core single frame. The key is to strictly avoid multiple points of connection in the core during the entire processing and assembly process to prevent such connections from weakening the performance of the core.

[0050] In one embodiment, if Figure 7 As shown, the target core single frame is provided with a grounding device 710 for preventing the occurrence of floating potential. The device can effectively ensure that the core outer mold can be reliably grounded, thereby effectively preventing the occurrence of floating potential phenomenon during the operation of the equipment and causing adverse effects on the core performance.

[0051] In one embodiment, after completing the assembly process of the target core single frame, in order to further enhance its electrical performance, in-depth insulation protection measures can be implemented on the core column and iron yoke surface of the target three-dimensional wound core. Specific means include but are not limited to painting resin paint and tying insulating tape, etc., to ensure that the overall insulation effect reaches the best state.

[0052] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
