Description

Technical Field

[0001] The embodiments of the present application relate to but are not limited to the technical field of transformer component production, and in particular to an amorphous alloy three-dimensional wound core with an insulating structure and a preparation method thereof. Background Art

[0002] As the demand for electricity continues to grow, the capacity of the transformer and the weight of the core are also increasing. In order to effectively support the increasingly heavy core, an outer core mold can be set on the outside of the core. This design not only enhances the structural stability of the core, but also facilitates the subsequent assembly and transportation process. However, in actual applications, since the core and the outer mold cannot be directly connected, it will cause multi-point grounding, which will not only affect the electrical performance of the transformer, but also may cause serious safety hazards. In addition, amorphous alloy cores are prone to debris during manufacturing and use. If these debris are not handled properly, they can easily fall into the coil when the transformer is running, causing faults such as short circuits or burning. Summary of the invention

[0023] 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. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0024] 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.

[0025] 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.

[0026] As the demand for electricity continues to grow, the capacity of transformers and the weight of the core also increase. In order to effectively support the increasingly heavy core, the industry generally adopts the method of setting a core outer mold on the outside of the core. This design not only enhances the structural stability of the core, but also facilitates the subsequent assembly and transportation process.

[0027] However, in actual applications, the core and the outer mold cannot be directly connected, otherwise it will lead to multi-point grounding, which will not only affect the electrical performance of the transformer, but also may cause serious safety hazards. In addition, amorphous alloy cores are prone to produce debris during manufacturing and use. If these debris are not handled properly, they are easy to fall into the coil during the operation of the transformer, causing short circuits or burnouts.

[0028] In view of this, the embodiment of the present application provides an amorphous alloy three-dimensional wound core with an insulating structure and a preparation method thereof, wherein the composition structure of the amorphous alloy three-dimensional wound core with an insulating structure includes a three-dimensional wound core, a frame mold insulation layer, an inter-frame insulation layer, an inter-mold insulation layer and a peripheral insulation layer. Among them, the three-dimensional wound core body includes a plurality of core single frames, which can be spliced ​​in pairs to form a three-dimensional wound core body, and the inter-frame insulation layer can be arranged on the splicing surface of the core single frame. The periphery of the core single frame is provided with a core outer mold to enhance the stability and supporting capacity of the structure. The frame mold insulation layer is located between the core single frame and the core outer mold, which not only plays an isolation role, but also can effectively prevent the falling of core debris, thereby ensuring the internal cleanliness and electrical safety of the transformer. At the same time, an inter-mold insulation layer is also provided between the core outer molds to further enhance the electrical isolation effect between the core outer molds. The peripheral insulation layer is arranged on the iron yoke and the core column of the three-dimensional wound core body, providing all-round insulation protection for the entire structure. The embodiment of the present application can ensure good isolation between the core and the core outer mold, and at the same time prevent the amorphous alloy core debris from damaging the insulation structure of the transformer, thereby improving the electrical performance and operation safety of the transformer.

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

[0030] See also Figures 1 to 3The amorphous alloy three-dimensional wound core with an insulating structure in the embodiment of the present application has a core structure including a three-dimensional wound core body 110, an inter-frame insulating layer 120, a frame mold insulating layer 140, an inter-mold insulating layer 150 and a peripheral insulating layer. These well-defined insulating structures together build an efficient and safe electrical insulation system to ensure that there is no direct electrical contact between the components. Specifically, the three-dimensional wound core body 110 can be spliced ​​together by three core single frames 111, and these core single frames 111 can be spliced ​​in pairs at a specific angle (such as a 60-degree angle) to form a compact and stable three-dimensional structure. The inter-frame insulating layer 120 can fit tightly on the splicing surface of each core single frame 111 to prevent the occurrence of multi-point grounding. Figure 2 As shown, the periphery of each core single frame 111 can be equipped with a core outer mold 130. The core outer mold 130 is used to insulate the core surface, which can effectively prevent the core debris from falling off, thereby ensuring the cleanliness and electrical safety of the inside of the transformer. Figure 3 As shown, the frame mold insulation layer 140 can be set in the gap between the core single frame 111 and the core outer mold 130, which effectively prevents the accidental conduction of current and ensures the reliability of insulation. In addition, the inter-mold insulation layer 150 can be set between the core outer molds 130 to provide an additional layer of electrical protection for the core outer mold 130. This layer of insulating material not only enhances the stability of the structure, but also significantly improves the safety performance of the equipment. The peripheral insulation layer can be tightly wrapped around the key parts of the three-dimensional wound core body, including the upper iron yoke, the lower iron yoke and the core column. This layer of insulation not only provides comprehensive electrical isolation, but also enhances the three-dimensional wound core's resistance to the external environment, ensuring the long-term stable operation of the equipment.

[0031] In one embodiment, the width of the frame mold insulation layer 140 between the core single frame 111 and the core outer mold 130 is greater than the splicing surface of the core outer mold 130 and the core single frame 111. It is worth noting that the wider frame mold insulation layer 140 can provide more ample electrical isolation space between the core single frame 111 and the core outer mold 130, thereby enhancing the overall electrical insulation performance and avoiding the occurrence of multi-point grounding. Secondly, since the frame mold insulation layer 140 can cover a wider area, it can more effectively prevent core debris or external contaminants from invading the splicing surface, thereby reducing mechanical wear or electrical performance degradation caused by debris accumulation or contamination.

[0032] In one embodiment, if Figure 2As shown, the outer insulating layer includes a first insulating layer 160, and the first insulating layer 160 can be coated on the iron yoke of the three-dimensional wound core. The first insulating layer 160 can include at least one layer of the first insulating member and / or at least one layer of the second insulating member. When the first insulating layer 160 includes at least one layer of the first insulating member and at least one layer of the second insulating member, these first insulating members and the second insulating members can be stacked according to a preset stacking rule. Specifically, a layer of the first insulating member can be evenly coated on the surface of the upper iron yoke and the lower iron yoke of the three-dimensional wound core. The insulating member can be made of high-performance insulating materials such as insulating paint and insulating glue. They have excellent adhesion and insulation performance and can effectively isolate the core from the external environment. Subsequently, a layer of the second insulating member is tightly covered on the first insulating member. The insulating member can be made of insulating paper, insulating board or insulating tape, etc. These materials not only have excellent insulation performance, but also have good mechanical strength and wear resistance, and can further protect the core from external damage. In order to further improve the insulation performance, one or more layers of the second insulating member can be added to the second insulating member to form a multi-layer stacking structure. Furthermore, a first insulating member may be brushed on the outside of the second insulating member. This multi-layer stacking design not only enhances the thickness and strength of the insulating layer, but also improves the overall electrical isolation effect. It should be noted that when the first insulating layer 160 only includes at least one first insulating member or at least one second insulating member, these insulating members may also be stacked according to a preset stacking rule, and this application does not limit this.

[0033] In one embodiment, if Figure 2As shown, the outer insulating layer may also include a second insulating layer 170, and the second insulating layer 170 may be coated on the core of the three-dimensional wound core to provide additional electrical protection for the core. The second insulating layer 170 includes at least one first insulating member, at least one second insulating member and / or a third insulating member. When the second insulating layer 170 includes at least one first insulating member, at least one second insulating member and a third insulating member, these first insulating members, second insulating members and third insulating members may be stacked and arranged according to a preset stacking rule, thereby achieving multi-level electrical isolation. In a specific implementation, a first insulating member (such as a high-performance insulating material such as insulating paint and insulating glue) may be uniformly coated on the core of the three-dimensional wound core to form a preliminary insulating barrier. Then, a third insulating member (such as an insulating tube) is used to surround it, providing additional support and insulation protection for the core. Then, a second insulating member (such as an insulating tape, etc.) is used to wrap it, further enhancing the insulation effect. Furthermore, a first insulating member may be brushed on the outside of the second insulating member. This multi-level stacking design not only improves the thickness and strength of the insulating layer, but also makes the insulation performance more stable and reliable. It should be noted that when the second insulating layer 170 only includes at least one layer of the first insulating member, at least one layer of the second insulating member or the third insulating member, these insulating members can also be stacked according to a preset stacking rule, and the present application does not impose any limitation on this.

[0034] In one embodiment, a third insulating layer may be added to the outer insulating layer, and the third insulating layer may be coated on the multiple core single frames 111 of the three-dimensional wound core, providing additional electrical protection for the multiple core single frames 111 of the three-dimensional wound core. The third insulating layer may be composed of at least one layer of the first insulating member and / or at least one layer of the second insulating member, and these insulating members may be stacked and arranged according to a preset stacking rule, thereby achieving multi-level electrical isolation. Specifically, since the corners of the core single frame 111 are more susceptible to electrical stress and mechanical stress, a layer of the first insulating member, such as insulating paint or insulating glue, may be evenly applied to the surface of the core at the corners of the core single frame 111 to form a preliminary insulating barrier. Then, multiple insulating strips are overlapped and bonded to the first insulating member, and these insulating strips not only enhance the insulation effect at the corners, but also enhance the overall strength of the structure. Finally, the core single frame 111 is wrapped with a second insulating member, such as insulating paper, insulating board, insulating strip, etc., to further enhance the insulation effect. It is worth noting that the design of the third insulating layer provides additional protection for the corners of the core single frame 111, which can not only prevent insulation damage caused by electrical stress concentration, but also improve the overall strength and stability of the structure. It should be noted that when the third insulating layer only includes at least one layer of the first insulating member or at least one layer of the second insulating member, these insulating members can also be stacked according to a preset stacking rule, and this application does not limit this.

[0035] It should be noted that the stacking method of the first insulating member and the second insulating member in the above embodiment can also be flexibly adjusted according to actual conditions to achieve the best insulation effect.

[0036] In one embodiment, a fourth insulating member is provided on the upper part of the core single frame 111. The fourth insulating member can be made of a breathable insulating material, such as a cloth tape, which not only has good insulation performance, but also has good air permeability, and can effectively prevent core debris from falling into the coil when the transformer is running. In a specific implementation, the reserved part on the upper part of each core may not be painted with insulating paint or insulating glue, and these parts without glue need to be wrapped with insulating and breathable materials such as cloth tape. This wrapping method not only ensures that the core debris will not fall out, but also maintains good air permeability, avoiding heat accumulation and performance degradation caused by the airtightness of the material.

[0037] It should be noted that the frame mold insulation layer 140, the inter-frame insulation layer 120, the inter-mold insulation layer 150 and the peripheral insulation layer can be arranged in any order. In addition, the preparation materials of the frame mold insulation layer 140, the inter-frame insulation layer 120, the inter-mold insulation layer 150 and the peripheral insulation layer can be any combination of insulating paint, insulating glue, insulating paper, insulating board, and insulating tape. The embodiments of the present application do not limit the material combination of these insulating layers.

[0038] See also Figure 4 , Figure 4 This is a flow chart of a method for preparing an amorphous alloy three-dimensional wound core with an insulating structure provided in an embodiment of the present application. By applying this preparation process, the amorphous alloy three-dimensional wound core with an insulating structure can be prepared. The process includes but is not limited to steps 410 to 440.

[0039] Step 410: Obtain multiple core single frames;

[0040] Step 420: a frame mold insulation layer is arranged on the periphery of each core single frame, and an inter-frame insulation layer is coated on the splicing surfaces of the core single frames, and the splicing surfaces of the core single frames are spliced ​​to obtain a three-dimensional wound core;

[0042] Step 440: an inter-mold insulating layer is provided between the core outer molds, and a peripheral insulating layer is provided on the iron yoke and the core column of the three-dimensional wound core to obtain a three-dimensional wound core with an insulating structure.

[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 peripheral insulating layer includes a first insulating layer and / or a second insulating layer, the first insulating layer includes at least one first insulating member and / or at least one second insulating member, and the second insulating layer includes at least one first insulating member, at least one second insulating member and / or a third insulating member. These insulating members can be stacked according to a preset stacking rule to enhance the electrical insulation performance of the core as a whole and avoid the occurrence of multi-point grounding.

[0045] In one embodiment, in the process of setting the outer insulating layer on the iron yoke and the core column of the three-dimensional wound core, the first insulating member can be first coated on the iron yoke of the three-dimensional wound core, and at least one layer of the second insulating member can be covered on the first insulating member; then the first insulating member can be coated on the core column of the three-dimensional wound core, and the third insulating member can be set on the periphery of the first insulating member, and the second insulating member can be covered on the third insulating member.

[0046] In one embodiment, the first insulating member may be made of high-performance insulating materials such as insulating paint and insulating glue, which have excellent adhesion and insulation properties and can effectively isolate the core from the external environment. The second insulating member may be made of insulating paper, insulating board or insulating tape, etc. These materials not only have excellent insulation properties, but also have good mechanical strength and wear resistance, and can further protect the core from external damage. The third insulating member may be made of an insulating tube, which can provide additional support and insulation protection for the core column by surrounding it.

[0047] In one embodiment, a third insulating layer is provided at the corner of the core single frame. The third insulating layer may be composed of at least one layer of the first insulating member and / or at least one layer of the second insulating member, and these insulating members may be stacked and arranged according to a preset stacking rule, thereby achieving multi-level electrical isolation. Specifically, a layer of the first insulating member, such as insulating paint or insulating glue, may be evenly applied to the surface of the core to form a preliminary insulating barrier. Then, a plurality of insulating strips are overlapped and adhered to the first insulating member, and these insulating strips not only enhance the insulation effect at the corner, but also enhance the overall strength of the structure. Finally, the core single frame is wrapped with a second insulating member, such as insulating paper, insulating board, insulating strip, etc., to further enhance the insulation effect.

[0048] It should be noted that since the preparation method of this embodiment can realize the preparation of the amorphous alloy three-dimensional wound iron core with an insulating structure as in the previous embodiment, the preparation method of this embodiment and the amorphous alloy three-dimensional wound iron core with an insulating structure in the previous embodiment have the same technical principles and the same beneficial effects.
