The suspension structure and installation method of three-dimensional wound iron core

[0001] Cross-reference to related applications

[0002] This disclosure claims priority to Chinese Patent Application No. 202411415782.5, filed on October 11, 2024, entitled “Suspension Structure of Three-Dimensional Winded Iron Core and Installation Method of Three-Dimensional Winded Iron Core”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of transformer technology, and in particular to a suspension structure for a three-dimensional wound core and its installation method. Background Technology

[0004] With the development of power grids, the requirements for energy-saving products are getting higher and higher. Amorphous alloy three-dimensional wound core transformers have advantages such as energy saving and environmental protection, and their applications are becoming more and more widespread.

[0005] Due to their material properties, amorphous alloy three-dimensional wound cores are prone to vibration and noise during excitation. The most direct way to solve this noise problem is to suspend the core, meaning to suspend it in the air. However, large-capacity transformers differ from small-capacity transformers. Small-capacity transformer cores are lightweight, and pads can be placed under the yoke to support the core and suspend it using the coils, thus supporting the coils. But for some large-capacity transformers, the weight of the three-dimensional wound core can sometimes reach 15 tons or more. If suspended in the same way as small-capacity transformers, the weight of the three-dimensional wound core is still supported by the coils, which could easily damage the coils. Summary of the Invention

[0006] This disclosure provides a suspension structure for a three-dimensional wound core and an installation method for the three-dimensional wound core, in order to solve the problem that the weight of the existing three-dimensional wound core is supported by the coil, which easily damages the coil.

[0007] To achieve the above objectives, the present disclosure adopts the following technical solution:

[0008] On the one hand, this disclosure provides a suspension structure for a three-dimensional wound iron core, comprising:

[0009] A support member, the support member including a first support portion and a connecting portion disposed on the first support portion, the first support portion being used to support the three-dimensional coiled iron core, and the connecting portion being used to extend at least partially to the side of the three-dimensional coiled iron core to limit the relative position between the three-dimensional coiled iron core and the first support portion.

[0010] The lower clamp includes a body connected to the connecting portion, the body extending at least partially below the first support portion, and the portion of the body extending below the first support portion having a gap with the first support portion.

[0011] An upper clamping member is connected to the end of the connecting portion opposite to the lower clamping member;

[0012] The upper clamp and the lower clamp are respectively used to clamp the coil from both ends of the coil of the three-dimensional coiled core.

[0013] In one possible embodiment of this disclosure, the first support portion includes:

[0014] A support plate, the support plate being used to support the three-dimensional coiled iron core, the shape of the support plate being adapted to the bottom shape of the three-dimensional coiled iron core;

[0015] Multiple side plates are provided, and the multiple side plates are connected to the side of the support plate. The side plates are used to restrict the position of the three-dimensional coiled iron core on the support plate from the side of the three-dimensional coiled iron core. The connecting part is provided on the side plate.

[0016] In one possible implementation of this disclosure, an upper limit component is also included;

[0017] The upper clamp is at least partially extended above the three-dimensional coiled iron core, and the portion of the upper clamp extending above the three-dimensional coiled iron core has a gap with the three-dimensional coiled iron core. The upper limit assembly is located within the gap and abuts against the three-dimensional coiled iron core to press the three-dimensional coiled iron core onto the first support portion.

[0018] In one possible embodiment of this disclosure, the upper limit assembly includes a first limiting member and a second limiting member. One side of the opposite sides of the first limiting member is used to abut against the three-dimensional coiled core, and the other side abuts against the second limiting member. The side of the second limiting member away from the first limiting member contacts the upper clamping member.

[0019] In one possible embodiment of this disclosure, the second limiting member is a first pad, which is engaged between the first limiting member and the upper clamping member.

[0020] In one possible embodiment of this disclosure, the second limiting member is an adjusting member, which is threadedly connected to the upper clamping member.

[0021] In one possible embodiment of this disclosure, the lower clamp further includes a second support portion connected to the body, the second support portion being at least partially extended below the coil to support the coil.

[0022] In one possible embodiment of this disclosure, a pressure pin is further included, which is threadedly connected to the upper clamp, and the upper clamp applies a clamping force to the coil through the pressure pin to fix the coil to the lower clamp.

[0023] In one possible embodiment of this disclosure, the connecting portion is provided in multiple sets, and each set of the connecting portion includes at least two connecting portions. The at least two connecting portions in each set are respectively used to limit different parts of the core column of the three-dimensional coiled iron core, so as to limit the position of the core column.

[0024] In one possible embodiment of this disclosure, the connecting portion is thickened at the connection point with the upper clamp and the lower clamp to form a protrusion.

[0025] On the other hand, this disclosure provides a method for installing a three-dimensional wound core, applied to the suspension structure of the three-dimensional wound core described in any one of the first aspects above, comprising:

[0026] The body of the lower clamp extends to the portion below the first support portion of the support member, is placed below the first support portion, and a gap is formed between the portion of the body extending below the first support portion and the first support portion.

[0027] A connecting portion that connects the main body and the support member;

[0028] A three-dimensional coiled iron core is installed on the support member, with the first support portion located below the three-dimensional coiled iron core to support the three-dimensional coiled iron core, and the connecting portion located at least partially on the side of the three-dimensional coiled iron core to limit the relative position between the three-dimensional coiled iron core and the first support portion.

[0029] An upper clamp is connected to the end of the connecting part that is away from the lower clamp;

[0030] The coil is wound onto the three-dimensional iron core and clamped between the upper clamp and the lower clamp.

[0031] This disclosure provides a suspension structure for a three-dimensional wound iron core. By setting a support member, the three-dimensional wound iron core is supported. The first support part of the support member and the body of the lower clamping member are spaced apart from each other, so that the support part supports the three-dimensional wound iron core in a suspended state, ensuring noise reduction effect. At the same time, the two ends of the connecting part are connected to the lower clamping member and the upper clamping member respectively, which can fix the coil wound on the three-dimensional wound iron core and also provide good limitation on the top of the three-dimensional wound iron core. In this suspension structure, the suspension force of the three-dimensional wound iron core acts on the support member, and the support member then transmits the force to the lower clamping member, so that the suspension of the three-dimensional wound iron core is detached from the support of the coil, avoiding damage to the coil due to stress.

[0032] This disclosure also provides a method for installing a three-dimensional wound core. By installing a support member on a lower clamp, the first support part supports the three-dimensional wound core, so that the weight of the three-dimensional wound core is transmitted from the connecting part to the lower clamp, detaching it from the support of the coil and preventing damage to the coil.

Detailed Implementation

[0038] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the drawings, not the entire structure.

[0039] In the description of this disclosure, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0040] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0042] This embodiment provides a suspension structure for a three-dimensional wound core. While ensuring the suspension of the three-dimensional wound core 200, it avoids pressure on the coil 300 from the three-dimensional wound core 200, thus preventing damage to the coil 300. As shown in Figures 1, 2, and 3, the suspension structure of the three-dimensional wound core includes a lower clamp 10, a support 20, and an upper clamp 30. The support 20 includes a first support portion 21 and multiple connecting portions 22 connected to the first support portion 21. The first support portion 21 supports the three-dimensional wound core 200, and the connecting portions 22 limit the three-dimensional wound core 200 from its side. That is, an insulating member can be used to separate the three-dimensional wound core 200 from the connecting portions 22. The connecting portions 22 press against the insulating member to limit the relative position between the three-dimensional wound core 200 and the first support portion 21. The lower clamp 10 includes a body 11 connected to the connecting portion 22. The body 11 extends at least partially below the first support portion 21, and there is a gap between the portion of the body 11 extending below the first support portion 21 and the first support portion 21. The upper clamp 30 is located at the upper end of the three-dimensional coil core 200 and is connected to the end of the connecting portion 22 opposite to the lower clamp 10. The upper clamp 30 and the lower clamp 10 are located at both ends of the coil 300, respectively, and clamp the coil 300 from both ends to fix the coil 300.

[0043] The suspension structure of the aforementioned three-dimensional coiled iron core uses a support member 20 to support the three-dimensional coiled iron core 200. The first support portion 21 of the support member 20 and the portion of the body 11 of the lower clamp 10 extending below the first support portion 21 are spaced apart, i.e., there is a gap between them. This allows the first support portion 21 to be suspended when supporting the three-dimensional coiled iron core 200, ensuring a noise reduction effect. At the same time, the two ends of the connecting portion 22 are connected to the lower clamp 10 and the upper clamp 30, respectively. While fixing the coil 300, the top of the three-dimensional coiled iron core 200 is also well limited. In this suspension structure, the suspension force of the three-dimensional coiled iron core 200 acts on the support member 20, and the support member 20 then transmits the force to the lower clamp 10, so that the suspension of the three-dimensional coiled iron core 200 is detached from the support of the coil 300, preventing the coil 300 from being damaged by the force.

[0044] As shown in Figure 3, the three-dimensional rolled iron core 200 is formed by splicing three iron core single frames 220. Since the outer side of each iron core single frame 220 is curved, after splicing, a core column 210 is formed at the corner of the three-dimensional rolled iron core 200. That is, the three pillars of the three-dimensional rolled iron core 200 extending in the vertical direction are the core columns 210.

[0045] It is understood that the three-dimensional rolled iron core 200 can also be other shapes, and is not limited to being formed by splicing three iron core single frames 220. This embodiment is not intended to limit it, but for ease of understanding, the example of the three-dimensional rolled iron core 200 being formed by splicing three iron core single frames 220 is used for illustration.

[0046] Optionally, as shown in Figure 2, the first support portion 21 includes a support plate 211 and a plurality of side plates 212. The shape of the support plate 211 is adapted to the bottom shape of the three-dimensional coiled iron core 200. The side plates 212 are connected to the side of the support plate 211. The side plates 212 are located on the side of the non-core column 210 of the three-dimensional coiled iron core 200, which restricts the position of the three-dimensional coiled iron core 200. The side plates 212 and the three-dimensional coiled iron core 200 can also be separated by an insulating member.

[0047] When the three-dimensional coiled iron core 200 is formed by splicing three core single frames 220, the support plate 211 is hexagonal and is used to support the bottom of the three-dimensional coiled iron core 200. Three side plates 212 are set at this time, and each side plate 212 is connected to one of the three sides of the non-core column 210 of the three-dimensional coiled iron core 200 corresponding to the support plate 211. Each side plate 212 is used to limit one side of the three-dimensional coiled iron core 200. Through the above arrangement, the side plates 212 limit the bottom side of the core single frame 220, further improving the stability of the installation of the three-dimensional coiled iron core 200.

[0048] In some embodiments of this disclosure, the connecting portion 22 is provided in multiple sets, and each set of connecting portions 22 includes at least two connecting portions 22. The at least two connecting portions 22 in each set are used to limit different parts of the core column 210 of the three-dimensional coiled iron core 200, so as to limit the position of the core column 210.

[0049] Optionally, as shown in Figures 2 and 3, when the three-dimensional coiled core 200 is formed by splicing three core single frames 220, the support member 20 is triangular. Each corner of the support member 20 is provided with a set of connecting parts 22 at intervals. Each set of connecting parts 22 includes two connecting parts 22, which are used to jointly limit one of the core columns 210 of the three-dimensional coiled core 200. Through the above arrangement, the two connecting parts 22 limit the two sides of the core column 210, and two connecting parts 22 are respectively provided on the outer side of the three core columns 210, so that the three-dimensional coiled core 200 is not easy to deviate after installation, and the installation stability is higher.

[0050] Optionally, as shown in FIG2, the connecting portion 22 has a protrusion 221 at the position where it connects with the upper clamp 30 and the lower clamp 10. With this configuration, when the connecting portion 22 is connected to the upper clamp 30 or the lower clamp 10, the wall thickness of the protrusion 221 is relatively thick, making the connecting portion 22 less prone to damage. Optionally, the connecting portion 22 is connected to the upper clamp 30 or the lower clamp 10 by screws. For example, the screws pass through the upper clamp 30 and the protrusion 221 sequentially to connect the two.

[0051] Optionally, as shown in Figure 1, the suspension structure of the three-dimensional coiled core further includes an upper limit assembly 40, the upper and lower ends of which abut against the top of the three-dimensional coiled core 200 and the upper clamp 30, respectively. This arrangement ensures that the upper clamp 30 and the top of the three-dimensional coiled core 200 are held in place by the upper limit assembly 40, thereby guaranteeing that the top of the three-dimensional coiled core 200 is firmly secured and ensuring the vertical stability of the three-dimensional coiled core 200 after installation.

[0052] In some embodiments of this disclosure, an upper limit assembly 40 is also included. The upper clamp 30 extends at least partially above the three-dimensional coil core 200. The portion of the upper clamp 30 extending above the three-dimensional coil core 200 has a gap with the three-dimensional coil core 200. The upper limit assembly 40 is located within the gap and abuts against the three-dimensional coil core 200 to press the three-dimensional coil core 200 onto the first support portion 21, thereby effectively limiting the position of the three-dimensional coil core 200 by the upper clamp 30 and the lower clamp 10.

[0053] Furthermore, the upper limit assembly includes a first limit member and a second limit member. One side of the opposite sides of the first limit member is used to abut against the three-dimensional coil core, and the other side abuts against the second limit member. The side of the second limit member away from the first limit member contacts the upper clamping member.

[0054] For example, as shown in Figure 1, the first limiting member is a limiting plate, and the second limiting member is a first pad (not shown). The lower side of the limiting plate abuts against the top of the three-dimensional coiled core 200, and the first pad is tensioned between the limiting plate and the upper clamping member 30. The first pad achieves tight abutment between the limiting plate and the top of the three-dimensional coiled core 200. Optionally, the three-dimensional coiled core 200 of different heights can be adapted by replacing the first pad with one of different heights.

[0055] In some embodiments of this disclosure, the first limiting member is a limiting plate, and the second limiting member is an adjusting member (not shown). The lower side of the limiting plate abuts against the top of the three-dimensional coiled iron core 200, and the adjusting member is threadedly connected to the upper clamp 30 and can abut against the top of the limiting plate 41. With the above configuration, by screwing the adjusting member, the adjusting member is pressed against the limiting plate, thereby making the limiting plate press against the top of the three-dimensional coiled iron core 200. The adjusting member is more convenient to adjust than the first pad solution, and there is no need to replace the adjusting member for three-dimensional coiled iron cores 200 of different heights.

[0056] Optionally, as shown in Figures 3 and 4, each three-dimensional coiled core 200 has a coil 300 surrounding its core column 210. The lower clamp 10 includes a body 11 and a second support portion 12. The body 11 is triangular and box-shaped, connected to multiple connecting portions 22. Each corner of the body 11 is provided with several second support portions 12, which are connected at an angle to the side wall of the body 11. The several second support portions 12 are used to jointly support the coil 300, that is, the second support portions 12 extend at least partially below the coil 300 and limit the bottom of the coil 300. With the above arrangement, after the coil 300 is installed, its bottom can be supported by several second support portions 12. In other words, the lower clamp 10 serves to support both the coil 300 and the three-dimensional coiled core 200, and the gravity applied by the two functions acts independently on the lower clamp 10, avoiding the three-dimensional coiled core 200 exerting a force on the coil 300.

[0057] Optionally, as shown in Figure 4, the suspension structure of the three-dimensional coil core also includes pressure pins 50. Each coil 300 is provided with several pressure pins 50. The pressure pins 50 are connected to the upper clamp 30 and are used to abut against the insulating pressure block 310 on the top of the corresponding coil 300. Through the above arrangement, the top of the coil 300 is pressed against by several pressure pins 50, so that the coil 300 is pressed against the second support part 12, ensuring the installation stability of the coil 300 in the vertical direction and preventing the coil 300 from shaking.

[0058] It should be noted that, as shown in Figure 4, insulating blocks 310 are provided at the top and bottom of the coil 300 to prevent short circuits caused by energization between the coil 300 and the metal parts at both ends (such as the pressure pins 310 or the second support part 12, etc.).

[0059] This embodiment also provides a method for installing a three-dimensional wound core, which uses the suspension structure of the three-dimensional wound core described above to install the three-dimensional wound core 200. The method for installing the suspension structure of the three-dimensional wound core includes:

[0060] S10: Connect the bottom of the multiple connecting parts 22 to the lower clamp 10;

[0061] S20: The three-dimensional coiled iron core 200 is installed on the support member 20 so that the first support part 21 supports the three-dimensional coiled iron core 200;

[0062] S30: The upper clamp 30 is placed on top of the three-dimensional coiled iron core 200, and the tops of the multiple connecting parts 22 are connected to the upper clamp 30.

[0063] S40: Wind the coil 300 onto the core column 210 corresponding to the three-dimensional coiled iron core 200, and assemble the body and lead wire;

[0064] S50: Install the upper limit assembly 40 between the three-dimensional coil core 200 and the upper clamp 30.

[0065] The above-mentioned method for installing a three-dimensional coiled iron core differs from that for a small three-dimensional coiled iron core. By installing the support member 20 on the lower clamp member 10, the support member supports the three-dimensional coiled iron core 200, so that the weight of the three-dimensional coiled iron core 200 is transmitted from the connecting part 22 to the lower clamp member 10, thus detaching it from the support of the coil 300 and preventing the coil 300 from being damaged.

[0066] It should be noted that a winding mold needs to be installed before winding the coil 300, which is existing technology and will not be elaborated here.

[0067] Optionally, the vessel body can also be dried. This step can be performed between S40 and S50 or after S50, and is not limited here.

[0068] Optionally, step S12 is set between S10 and S20: a buffer is provided on the first support 21 to reduce friction on the bottom of the three-dimensional coiled core 200.

[0069] Optionally, step S11 is further included between S10 and S20: a second pad is placed between the first support 21 and the lower clamp 10, and step S41 is further included between S40 and S50: the pad is removed. This can alleviate the pressure on the support 20 caused by the heavy weight of the three-dimensional coiled core 200 during installation. After the installation is stable, the pad is removed to ensure the suspension setting of the three-dimensional coiled core 200.

[0070] Obviously, the above embodiments of this disclosure are merely examples for clear illustration and are not intended to limit the implementation of this disclosure. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of this disclosure. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of the claims of this disclosure.
