Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a high-voltage transformer skeleton. Background Art

[0002] In the field of high-frequency transformer skeletons, one of the primary challenges is the lack of systematic structural innovation to ensure stability and anti-collision capabilities during product transfer and logistics transportation, which directly leads to a high rate of damage to skeleton raw materials during transportation, while traditional solutions that rely on expensive packaging materials such as pearl cotton significantly increase the cost burden. In addition, although some high-voltage transformer skeletons have tried to optimize the interlayer withstand voltage performance of the high-voltage winding side through layered slot design, the excessively high partition design can easily cause winding damage during cross-line operation, becoming another technical problem that needs to be solved urgently.

[0003] To overcome the above challenges, technicians in this field have conducted in-depth exploration and innovation. Taking the Chinese patent CN213366351U as an example, although the patent has cleverly designed a transformer skeleton, which guides the input line of the first winding to smoothly extend into the bottom of the winding through the inclined slope, effectively avoiding the high-voltage sparking and wire breaking problems caused by voltage difference, it does not fully solve the key needs of skeleton transportation stability and high-voltage winding cross-line protection. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a high-voltage transformer skeleton.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A high-voltage transformer skeleton comprises a skeleton body, wherein both sides of the end surface of the skeleton body are respectively provided with a clamping groove and a clamping boss, and adjacent skeleton bodies are connected to form an integrated convex-concave mortise and tenon structure through the clamping groove and the clamping boss; the windings on the skeleton body are divided into a filament winding, a low-voltage winding and a high-voltage winding, wherein: the layered grooves of the high-voltage winding are provided with a cross-line relief structure for reducing the cross-line drop.

[0007] This technical solution solves the problems of the stability and anti-collision of the traditional skeleton during transportation by introducing the convex-concave tenon-mortise connection and the cross-line buffer structure, and also optimizes the winding process on the high-voltage winding side, reducing the risk of winding damage. Specifically, a clamping groove and a clamping boss are respectively arranged on both sides of the end face. The formed integrated convex-concave tenon-mortise structure not only greatly enhances the stability and anti-collision ability of the skeleton during transportation, effectively reducing the damage rate of raw materials during transportation, but also realizes cost savings and efficient use of space by reducing the use of additional packaging materials (such as EPE); a cross-line buffer structure is added to the layered slots, and a bayonet with a smooth edge transition is used, so that the high-voltage winding can smoothly transition when crossing the layered slots with a large height difference, effectively avoiding the friction and scratching of the winding caused by too large a cross-line height difference, thus ensuring the safety and reliability of the high-voltage winding.

[0008] In addition, the high-voltage transformer skeleton proposed above according to the present invention may also have the following additional technical features:

[0009] According to an embodiment of the present invention, the concave shape of the clamping groove matches the convex shape of the clamping boss, and after the convex-concave tenon-mortise structure is spliced, the left and right skeleton bodies are tightly fixed and connected.

[0010] In this technical solution, when the clamping groove and the clamping boss are spliced, a mechanical locking effect will be generated between the convex-concave tenon-mortise structures; the mechanical locking effect is achieved by the combined action of shape complementarity and the friction force between the contact surfaces. After the convex part of the clamping boss is inserted into the clamping groove, it will be subjected to pressure from the side wall of the groove, thereby generating friction force; at the same time, the contact between the clamping boss and the bottom of the clamping groove also increases the overall stability.

[0011] According to an embodiment of the present invention, the skeleton bodies where the clamping groove and the clamping boss are located have the same height.

[0012] In this technical solution, the consistency of the height helps to reduce the error during splicing, ensuring that each skeleton body can maintain a horizontal or vertical alignment state after splicing; because each skeleton body is on the same horizontal plane, the connection force between them can be evenly distributed, reducing stress concentration and deformation caused by height differences, and also facilitating transportation in the packing box.

[0013] According to an embodiment of the present invention, the high-voltage transformer skeleton is a unit structure. During transportation, after the convex-concave tenon-mortise structures are assembled with a plurality of skeletons, the skeleton bodies are connected into an integrated structure in the packing box.

[0014] In this technical solution, on the one hand, the integrated structure reduces the relative movement and collision between the skeletons, reducing the risk of transportation damage; on the other hand, the overall packaging reduces the use of packaging materials, lowers the packaging cost, and simplifies the transportation operation; at the same time, the integrated structure is also convenient for handling and stacking, improving the transportation efficiency.

[0015] According to an embodiment of the present invention, the low-voltage winding includes a winding shaft I, a winding guide groove, and a wire outlet hole; the low-voltage winding is wound around the winding shaft I and extends out through the winding guide groove to the wire outlet hole.

[0016] In this technical solution, the winding shaft I provides support and positioning for the winding, ensuring the stability and consistency of the winding during the winding process; the winding guide groove makes the winding process smoother, reducing the crossing and confusion of the winding wires, and improving the neatness and tightness of the winding; the setting of the wire outlet hole facilitates the leading out of the winding leads. The low-voltage winding adopts a modular structure, and components such as the winding shaft I, the winding guide groove, and the wire outlet hole together form a relatively independent winding unit.

[0017] According to an embodiment of the present invention, the high-voltage winding includes a winding shaft II, a layered slot, a layered baffle, and a group winding shaft III; one end of the high-voltage winding is connected to the winding pin, the high-voltage winding is wound around the winding shaft II, enters the layered slot through one end of the layered baffle, and then extends out of the high-voltage winding through the other end of the layered baffle and winds around the group winding shaft III, and finally winds around the winding pin at the other end of the high-voltage winding.

[0018] In this technical solution, the design of the high-voltage winding uses two main winding shafts, namely the winding shaft II and the group winding shaft III, as well as the layered slot and the layered baffle as transition and guiding structures. The use of the layered slot and the layered baffle not only provides physical support and guidance for the winding, but also may enhance the insulation performance of the winding in terms of structure.

[0019] According to an embodiment of the present invention, the winding pins are respectively arranged on both sides of the winding shaft II and the group winding shaft III.

[0020] In this technical solution, the winding pins not only serve as electrical connection points, but also play a certain supporting role. They firmly fix the high-voltage winding on the winding shaft and the group winding shaft, preventing the winding from loosening or falling off under vibration or mechanical shock.

[0021] According to an embodiment of the present invention, the cross-wire relief structure of the layered slot is a bayonet with a smooth edge transition. The high-voltage winding smoothly transitions from the high-drop layered slot to the cross-wire relief structure, preventing the high-voltage winding from being scratched by the drop friction.

[0022] In this technical solution, the high-voltage winding is usually wrapped with an insulating layer. If the winding is scratched due to friction caused by a drop during movement, it is very likely to damage its insulating layer, thereby reducing the overall insulation performance of the electrical equipment and increasing the risk of failure. The setting of the cross-line relief structure not only reduces the friction and resistance during the installation of the winding, but also improves the assembly accuracy and efficiency; because the winding can enter the specified slot more smoothly through the relief structure, reducing the rework and maintenance costs caused by difficult assembly.

[0023] Compared with the prior art, the present utility model has the following beneficial effects:

[0024] By introducing the convex-concave mortise and tenon connection and the cross-line relief structure, not only the stability and anti-collision problems of the traditional skeleton during transportation are solved, but also the winding process on the high-voltage winding side is optimized, reducing the risk of winding damage.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment 1

[0033] As Figures 1 to 5As shown in the figure, this embodiment provides a high-voltage transformer skeleton, including a skeleton body 1. On both sides of the end face of the skeleton body 1, there are respectively a clamping groove 1-1 and a clamping boss 1-2. Adjacent skeleton bodies 1 are connected into an integrated convex-concave mortise and tenon structure through the clamping groove 1-1 and the clamping boss 1-2; the windings on the skeleton body 1 are divided into a filament winding 1-11, a low-voltage winding, and a high-voltage winding. Among them: a wire-crossing slow-down structure 1-8-1 for reducing the wire-crossing drop is provided in the layered slot 1-7 of the high-voltage winding.

[0034] As Figures 1 to 5 shown in the figure, by introducing the convex-concave mortise and tenon connection and the wire-crossing slow-down structure 1-8-1, this technical solution not only solves the problems of stability and anti-collision in the transportation of traditional skeletons, but also optimizes the wire-winding process on the high-voltage winding side and reduces the risk of winding damage. Specifically, a clamping groove 1-1 and a clamping boss 1-2 are respectively provided on both sides of the end face, and the formed integrated convex-concave mortise and tenon structure not only greatly enhances the stability and anti-collision ability of the skeleton during transportation, effectively reducing the damage rate of raw materials during transportation, but also realizes cost savings and efficient use of space by reducing the use of additional packaging materials (such as EPE); a wire-crossing slow-down structure 1-8-1 is added at the position of the layered slot 1-7, and a bayonet with a smooth edge transition is adopted, so that the high-voltage winding can smoothly transition when crossing the layered slot 1-7 with a large drop, effectively avoiding the friction and scratching of the winding caused by too large a wire-crossing drop, thus ensuring the safety and reliability of the high-voltage winding.

[0035] In addition, according to the above-mentioned high-voltage transformer skeleton proposed by the present invention, the following additional technical features may also be possessed:

[0036] According to an embodiment of the present invention, the concave shape of the clamping groove 1-1 matches the convex shape of the clamping boss 1-2, and after the convex-concave mortise and tenon structure is spliced, the left and right skeleton bodies 1 are tightly and fixedly connected.

[0037] In this technical solution, when the clamping groove 1-1 and the clamping boss 1-2 are spliced, a mechanical locking effect will be generated between the convex-concave mortise and tenon structures; the mechanical locking effect is achieved by the combined action of shape complementarity and the friction force between the contact surfaces. After the convex part of the clamping boss 1-2 is inserted into the clamping groove 1-1, it will be subjected to the pressure from the side wall of the groove, thereby generating a friction force; at the same time, the contact between the clamping boss 1-2 and the bottom of the clamping groove 1-1 also increases the overall stability.

[0038] According to an embodiment of the present invention, the heights of the skeleton bodies 1 where the clamping grooves 1-1 and the clamping bosses 1-2 are located are the same.

[0039] In this technical solution, a high degree of consistency helps to reduce the error during splicing, ensuring that each skeleton body 1 can maintain a horizontal or vertical alignment state after splicing; since each skeleton body 1 is on the same horizontal plane, the connection force between them can be evenly distributed, reducing stress concentration and deformation caused by height differences, and also facilitating transportation in a packing box.

[0040] According to an embodiment of the present invention, the high-voltage transformer skeleton is a unit structure. During transportation, after the convex and concave tenon and mortise structures are assembled in a plurality of skeletons, the skeleton bodies are connected into an integral structure in the packing box.

[0041] In this technical solution, on the one hand, the integral structure reduces the relative movement and collision between the skeletons, reducing the risk of transportation damage; on the other hand, the overall packaging reduces the use of packaging materials, reduces the packaging cost, and simplifies the transportation operation; at the same time, the integral structure is also convenient for handling and stacking, improving the transportation efficiency.

[0042] According to an embodiment of the present invention, the low-voltage winding includes a winding shaft I 1-3, a winding guide groove 1-4, and an outlet hole 1-5; the low-voltage winding is wound around the winding shaft I 1-3 and extends out through the winding guide groove 1-4 to the outlet hole 1-5.

[0043] In this technical solution, the winding shaft I 1-3 provides support and positioning for the winding, ensuring the stability and consistency of the winding during the winding process; the winding guide groove 1-4 makes the winding process smoother, reducing winding crossing and chaos, and improving the neatness and tightness of the winding; the setting of the outlet hole 1-5 facilitates the extraction of the winding leads. The low-voltage winding adopts a modular structure, and components such as the winding shaft I 1-3, the winding guide groove 1-4, and the outlet hole 1-5 together form a relatively independent winding unit.

[0044] According to an embodiment of the present invention, the high-voltage winding includes a winding shaft II 1-6, a layered groove 1-7, a layered baffle 1-8, and a group winding shaft III 1-9; one end of the high-voltage winding is connected to a winding pin 1-10, the high-voltage winding is wound around the winding shaft II 1-6, enters the layered groove 1-7 through one end of the layered baffle 1-8, then extends out of the high-voltage winding through the other end of the layered baffle 1-8 and is wound around the group winding shaft III 1-9, and finally wound around the winding pin 1-10 at the other end of the high-voltage winding.

[0045] In this technical solution, the design of the high-voltage winding adopts two main winding shafts, namely the winding shaft II 1-6 and the group winding shaft III 1-9, as well as the layered groove 1-7 and the layered baffle 1-8 as transition and guiding structures. The use of the layered groove 1-7 and the layered baffle 1-8 not only provides physical support and guidance for the winding, but also may enhance the insulation performance of the winding in terms of structure.

[0046] According to an embodiment of the present utility model, the winding pins 1-10 are respectively arranged on both sides of the winding shaft II 1-6 and the group winding shaft III 1-9.

[0047] In this technical solution, the winding pins 1-10 not only serve as electrical connection points but also play a certain supporting role. They firmly fix the high-voltage winding on the winding shaft and the group winding shaft, preventing the winding from loosening or falling off under vibration or mechanical shock.

[0048] According to an embodiment of the present utility model, the wire-crossing buffer opening structure 1-8-1 of the layered slot 1-7 is a bayonet with a smooth edge transition. The high-voltage winding smoothly transitions from the high-drop layered slot 1-7 to the wire-crossing buffer opening structure 1-8-1, preventing the high-voltage winding from being scratched due to drop friction.

[0049] In this technical solution, the high-voltage winding is usually wrapped with an insulating layer. If the winding is scratched due to drop friction during movement, it is very likely to damage its insulating layer, thereby reducing the overall insulation performance of the electrical equipment and increasing the risk of failure. The setting of the wire-crossing buffer opening structure 1-8-1 not only reduces the friction and resistance during the installation of the winding but also improves the assembly accuracy and efficiency; because the winding can enter the designated slot more smoothly through the buffer opening structure, reducing the rework and maintenance costs caused by difficult assembly.

[0050] The usage process of the above embodiment is as follows:

[0051] As Figures 1 to 5 shown, first, in terms of the transportation plan, the splicing is carried out through the clamping groove 1-1 and the clamping boss 1-2 to complete the mortise and tenon connection, making the plural high-voltage skeletons form an integrated structure, which can ensure a stable and reliable state of the skeleton body 1 in the transport box; secondly, in the conventional winding, the high and low voltage sides are divided. The low-voltage winding is wound on the winding shaft I 1-3 and extends out through the guide groove to the wire outlet hole 1-5. One end of the high-voltage winding is connected to the winding pin 1-10 and is integrally wound on the winding shaft II 1-6. The winding passes through one end of the layered baffle 1-8, enters the layered slot 1-7, and then the high-voltage winding extends out from the other end of the layered baffle 1-8 and is wound on the winding shaft III, and finally wound on the winding pin 1-10 at the other end. During this period, the wire-crossing buffer opening structure 1-8-1 on the layered baffle 1-8 protects the high-voltage winding from being damaged when passing the wire.

[0052] Although the present utility model has been described in detail by referring to the accompanying drawings and in conjunction with the preferred embodiments, the present utility model is not limited thereto. Without departing from the spirit and essence of the present utility model, those of ordinary skill in the art can make various equivalent modifications or substitutions to the embodiments of the present utility model, and all such modifications or substitutions should fall within the scope of the present utility model. / Any person skilled in the art within the technical scope disclosed by the present utility model can easily conceive of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
