Description

Compared to traditional electrical steel strip, these transformers typically exhibit lower total losses. As electricity consumption continues to increase, so too do the demands on transformer capacity and performance. This increase in transformer capacity also leads to an increase in core volume. Because amorphous alloy strip is inherently thin and soft, and easily affected by the external environment, cores manufactured using this material are prone to problems such as poor core strength, deformation at the joints between core frames, and difficulty in assembling the frames. This, to a certain extent, limits the development and promotion of large-capacity, high-voltage amorphous alloy three-dimensional wound core transformers.

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] 1 and 2 , an amorphous alloy three-dimensional wound core according to an embodiment of the present invention includes a core single frame 100 and a reinforcement member 200. The core single frame 100 includes an inner support frame 110 in a hollow rectangular shape and a material strip group 120. The material strip group 120 is wound around the outer side of the inner support frame 110 to form the core single frame 100. The core single frame 100 is formed with two vertical struts 130 perpendicular to the horizontal plane and two horizontal struts 140 parallel to the horizontal plane. The vertical struts 130 and the horizontal struts 140 are staggered and transitioned through rounded corners.

[0039] Specifically, the material belt group 120 includes a plurality of first material belts 122, a plurality of second material belts 123 and a plurality of third material belts 124. The first material belt 122, the second material belt 123 and the third material belt 124 are wound around the inner support frame 110 in sequence, that is, the first material belt 122 is wound around the inner support frame 110, the second material belt 123 is wound around the first material belt 122, and the third material belt 124 is wound around the second material belt 123. The material belt 122 points to the direction of the third material belt 124 (that is, the inner support frame 110 is from the inside to the outside). The first material belt 122, the second material belt 123 and the third material belt 124 slide groove are connected with the width of the belt. The vertical support 130 and the horizontal support 140 are stacked in an offset manner in a continuously changing trend, so that the cross section of the vertical support 130 and the vertical cross section of the horizontal support 140 are approximately semicircular. At this time, the inclined surface of the vertical support 130 facing away from the inner support frame 110 is the first splicing surface 121; in particular, the degree of offset between the second material strip 123 and the first material strip 122 is relatively large, so that an annular groove 101 is formed around the inner support frame 110 between the first material strip 122, the second material strip 123, and the third material strip 124, and the part of the annular groove 101 passing through the first splicing surface 121 is the first groove 1201. The material strip group 120 is divided into a first material strip 122, a second material strip 123 and a third material strip 124. The first material strip 122, the second material strip 123 and the third material strip 124 are wound step by step to form the first groove 1201, which can facilitate the molding of the first groove 1201 and facilitate the user to control the size of the first groove 1201, thereby improving the yield rate of the single core frame 100 processing.

[0040] 1 and 2 , it can be understood that the reinforcement 200 and the first splicing surface 121 are arranged in a one-to-one correspondence, and the reinforcement 200 includes an insulating plate 220 and a reinforcement plate 210. One side of the insulating plate 220 is provided with a second splicing surface 221 that matches the shape of the first splicing surface 121. The second splicing surface 221 is provided with a first protrusion 222. The first protrusion 222 and the first groove 1201 are fit together in an interference fit so that the second splicing surface 221 and the first splicing surface 121 fit together, thereby fixing the insulating plate 220 to the first splicing surface 121. The reinforcement plate 210 is located on the side of the insulating plate 220 away from the first splicing surface 121 and is detachably connected to the insulating plate 220. The reinforcement member 200 is divided into an insulating plate 220 and a reinforcing plate 210. The reinforcing plate 210 is made of a high-strength, high-rigidity alloy, while the insulating plate 220 is made of an insulating material such as rubber or stainless steel. The insulating plate 220 is located between the reinforcing plate 210 and the first splicing surface 121. This allows the reinforcing plate 210 to stably secure the core single frame 100 while preventing problems such as multiple grounding points caused by the material strip assembly 120 contacting the reinforcing plate 210, effectively improving operational stability and safety. Furthermore, the reinforcing plate 210 and the insulating plate 220 are detachably connected, effectively increasing the modularity of the three-dimensional wound core and facilitating subsequent maintenance and replacement of the insulating plate 220 or reinforcing plate 210.

[0041] As shown in Figure 2, it can be understood that the insulating plate 220 has a second groove 2202 on the side facing the reinforcing plate 210. The outer wall of the second groove 2202 protrudes from the end surface of the insulating plate 220 to form a first protrusion 222. The reinforcing plate 210 has a second protrusion 211, which engages with the first groove 1201 to mate the reinforcing plate 210 with the insulating plate 220. The provision of the second groove 2202 and the second protrusion 211 makes the connection structure between the reinforcing plate 210 and the insulating plate 220 similar to the connection structure between the insulating plate 220 and the first splicing surface 121, effectively improving the consistency of the three-dimensional wound core structure and enhancing the assembly convenience of the reinforcing member 200. The outer wall of the second groove 2202 protrudes to form the first protrusion 222, making the thickness of the insulating plate 220 uniform, thereby facilitating the mold opening process of the insulating plate 220 and reducing the production cost of the insulating plate 220.

[0042] 1 and 2 , it can be understood that there are three core single frames 100, which are arranged in an equilateral triangle. The two first splicing surfaces 121 between two adjacent core single frames 100 are arranged opposite to each other, and the two adjacent vertical pillars 130 are fixed by coils wound around the vertical pillars 130 to form a cylindrical core column 131. At this time, the two reinforcement members 200 between the two opposite first splicing surfaces 121 are located at the center of the core column 131, and the reinforcement plates 210 of the two reinforcement members 200 are abutted and matched. The surface of the three-dimensional wound core is tied with binding tape and coated with curing glue. The binding tape and curing glue can not only improve the strength of the three-dimensional wound core, but also prevent the core debris from falling, thereby improving the reliability of the core. In the vertical direction, the two ends of the three-dimensional wound core are respectively connected with clamps, which are iron yokes with equilateral triangle grooves. The equilateral triangle grooves match the end shapes of the three-dimensional wound core. The clamps are connected by pull plates or pull screws. The clamps at both ends can clamp the coil in the vertical direction. The clamps and the reinforcement 200 cooperate to greatly improve the installation stability of the three-dimensional wound core.

[0043] As shown in Figure 2, it can be understood that a third groove 2101 is provided on the side of the reinforcing plate 210 facing away from the insulating plate 220. The outer wall of the third groove 2101 protrudes from the end surface of the reinforcing plate 210 to form a second protrusion 211. The third grooves 2101 of the two abutting reinforcing plates 210 are arranged relative to each other and form an installation channel 201. The installation channel 201 is used to allow the pull plate or pull screw of the three-dimensional wound core to pass through. By providing the third groove 2101, the third grooves 2101 of the two reinforcing plates 210 between two adjacent core single frames 100 are installed with the channel 201. When the user installs the clamp, the pull plate or pull screw on the clamp can be passed through the installation channel 201. At this time, not only is the torque of the clamp basically balanced and minimized, thereby increasing the clamp's pressing force on the coil, but it also eliminates the need to consider the insulation distance from the coil to the pull plate or pull screw, reducing the volume of the transformer body and saving transformer production costs.

[0044] It can be understood that by providing the inner support frame 110, it is beneficial to the winding of the amorphous alloy strip, the mechanical strength of the core single frame 100 is improved, and the assembly convenience of the core single frame 100 is improved; by providing the reinforcement 200, on the one hand, the first protrusion 222 of the reinforcement 200 and the first groove 1201 of the first splicing surface 121 are snapped together, which facilitates the assembly and use of the reinforcement 200; on the other hand, after the three-dimensional wound core is assembled, the relative reinforcements 200 abut against each other to ensure the stress balance between the core single frames 100, The reinforcement 200 supports and fixes the material strip group 120 made of amorphous alloy through the flat second splicing surface 221. After the coil is wound around two adjacent vertical pillars 130 to form a core column 131, the reinforcement 200 at the center of the core column 131 fixes the material bag groups on both sides, avoiding the mutual stacking and interference of the thinner amorphous alloy material strip groups 120 between the two iron core single frames 100, thereby improving the mechanical strength and deformation resistance of the core column 131, thereby preventing the deformation of the core column 131 due to the excessive size of the core column 131. The inner support frame 110 and the reinforcement 200 cooperate to effectively improve the mechanical strength and deformation resistance of the iron core. When the user assembles the three-dimensional wound iron core, even if the single core frame 100 is large in size, it is only necessary to align the reinforcement plate 210 without worrying about the deformation of the vertical support 130, thereby reducing the difficulty of manufacturing and assembling the three-dimensional wound iron core. In addition, the core column 131 of the assembled three-dimensional wound iron core also has sufficient strength to avoid deformation, so that the material strip group 120 made of amorphous alloy can meet the assembly requirements of large-volume iron cores with larger capacity and higher voltage.

[0045] As shown in FIG4 , it can be understood that the third material strip 124 is provided with a limiting section 1241. The limiting section 1241 is an annular flange structure formed by the third material strip 124 being wound around the second material strip 123 and suspended on the side of the first groove 1201 facing away from the second material strip 123. A slot 2201 is formed between the first protrusion 222 facing the side wall of the third material strip 124 and the second splicing surface 221. The slot 2201 and the limiting section 1241 engage with each other. By providing the limiting section 1241, the limiting section 1241 transforms the original obtuse angle structure between the third material strip 124 and the second material strip 123 into an acute angle structure. The limiting section 1241 is snapped into the slot 2201 between the first protrusion 222 and the second splicing surface 221, which can limit the insulating plate 220, further improving the installation stability of the insulating plate 220 and improving the structural tightness of the core column 131.

[0046] A method for manufacturing a three-dimensional wound core according to one embodiment of the present invention is applied to the three-dimensional wound core according to the above embodiment. The manufacturing method includes:

[0047] S200, repeat step S100 to manufacture three core single frames 100;

[0048] S300, manufacturing a reinforcement member 200 according to the first splicing surface 121, forming a second splicing surface 221 matching the first splicing surface 121 on one side of the reinforcement member 200, and processing a first protrusion 222 on the second splicing surface 221 according to the first groove 1201;

[0049] S400, repeating step S300 to manufacture six reinforcement members 200;

[0050] S500, insert the first protrusion 222 into the first groove 1201 accordingly, so that the first splicing surfaces 121 on both sides of each core single frame 100 are respectively connected to the corresponding reinforcement member 200;

[0051] S600 , three core single frames 100 are arranged in an equilateral triangle, and single sides of two adjacent core single frames 100 are bound and fixed using coils so that the two reinforcement members 200 between the two adjacent core single frames 100 abut against each other.

[0052] After the three core single frames 100 are connected and fixed by the coils, they can be tied with binding tape and coated with curing glue, and then the clamps are installed to improve the overall stability of the three-dimensional wound core.

[0053] Since the three-dimensional wound core processing and manufacturing method is applied to all technical solutions of the three-dimensional wound core of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0054] It is understood that the steps of preparing the material strip assembly 120 and the inner support frame 110 include:

[0055] S110, determining the length of the strip group 120 according to the volume size of the three-dimensional wound core;

[0056] S120 , processing the amorphous alloy strip into a plurality of first strips 122 , a plurality of second strips 123 , and a plurality of third strips 124 according to length dimensions.

[0057] Before winding the material strip group 120 , the material strip group 120 is divided into a first material strip 122 , a second material strip 123 and a third material strip 124 , which can facilitate the subsequent winding and forming of the first groove 1201 and effectively improve the production efficiency of the three-dimensional wound core.

[0058] It is understandable that the steps of making the reinforcement member 200 include:

[0059] S310, manufacturing an insulating board 220 according to the first splicing surface 121;

[0060] S320 , manufacturing the reinforcing plate 210 based on the insulating plate 220 , wherein the reinforcing plate 210 and the insulating plate 220 match in appearance.

[0061] Since the first splicing surface 121 is the inclined surface on one side of the vertical pillar 130 (the width of the first splicing surface 121 is the diameter of the cross section of the vertical pillar 130), the size of the first splicing surface 121 can approximately represent the size of the core column 131. After determining the first splicing surface 121, the insulating plate 220 and the reinforcing plate 210 are manufactured. While facilitating the subsequent assembly of the reinforcement 200, the reinforcing plate 210 and the insulating plate 220 are ensured to be able to fix the first splicing surface 121 formed by the material strip group 120, thereby ensuring that the core column 131 after the three-dimensional wound iron core is assembled has sufficient mechanical strength and anti-deformation performance, thereby effectively improving the structural tightness of the core column 131.

[0062] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
