Description

Technical Field

[0001] This invention relates to the field of transformer coil manufacturing technology, and in particular to a method for generating a development diagram to guide the winding of tangled coils. Background Technology

[0002] In the field of transformer manufacturing, especially in high-voltage and ultra-high-voltage transformers, entangled coil structures are commonly used to improve the electric field distribution between windings. For example... Figure 1 As shown, the entangled coil includes an insulating cylinder 1, a support bar 2, a pad 3, and a conductor 4. This structure is typically composed of multiple coils wound in opposite directions and interlaced axially. Each coil is made up of multiple parallel conductors wound continuously radially, and they are electrically connected in series through a specific "entanglement" connection. Its winding process is complex and requires extremely high precision.

[0003] Currently, the winding production process mainly relies on traditional coil development diagrams as guidance. Existing development diagrams are typically drawn in a coaxial, parallel direction, representing adjacent coils in a simple stacked manner, such as... Figure 2 As shown in the diagram, A and X represent wire exits; S1 and S2 represent bottom "S" bends; and S3 and S4 represent alignment corrections. This traditional form of representation has significant limitations, leading to a disconnect between the information on the drawings and actual production.

[0004] Structural details are severely lacking: the traditional views cannot show the specific number of turns for each individual coil and the radial layer-by-layer arrangement of the conductors. Operators cannot visually see the actual conductor stacking at any given position from the drawings.

[0005] Missing radial conductor information: Traditional drawings cannot clearly and quantitatively show the actual number of radial conductors at each support position of the coil. Operators cannot predict whether the radial dimension will abnormally increase at a specific position due to conductor repositioning or stacking. This is particularly dangerous in ultra-high voltage products, as excessive local radial dimensions can cause electric field distortion, leading to significant quality hazards such as partial discharge or even insulation breakdown.

[0006] Ambiguous spatial relationships: Due to simplified views, the specific spatial path of each conductor at each span is not accurately simulated on the unfolded drawing. Spatial conflicts between conductor leads and internal structural components such as S-bends and spacers cannot be detected during the drawing stage. This often results in situations where the leads are blocked and cannot be led out only after winding is complete, causing serious rework and material waste.

[0007] The alignment status is not intuitive: the S-bends between adjacent wire discs must be radially aligned at the same position; otherwise, a "scissor edge" will be formed, affecting mechanical stability and electrical connection reliability. Traditional drawings use an overlay method, making it difficult to intuitively verify this precise alignment relationship. They rely on the operator's experience and judgment, which poses a quality risk.

[0008] Therefore, the existing technology lacks a method for generating unfolded diagrams that can comprehensively and accurately visualize the winding details of each coil, the radial structure of the coil, the spatial path of the conductor, and the key positional relationships during the design stage. This results in many hidden risks in the production process and makes it difficult to effectively improve quality control and first-time success rate. Summary of the Invention

[0009] The technical problem to be solved and the technical task proposed by this invention is to improve and refine existing technical solutions, and to provide a method for generating development diagrams to guide the winding of tangled coils. This aims to establish a standardized, visualized, and precise drawing method to achieve a high degree of consistency between the drawings and actual production, thereby preventing potential quality problems at the source and improving production efficiency and first-pass yield. To this end, this invention adopts the following technical solution.

[0010] A method for generating a development diagram to guide the winding of tangled coils includes the following steps: 1) Obtain the winding parameters of the entangled coil, including the number of support bars n, the number of parallel wires k for the single coil, and the total number of turns m for the single coil, where the total number of wires used for the single coil is 2k; 2) Unfold the coil insulation cylinder along its circumference to form a horizontal baseline; divide the unfolded circumference into n equal sections using the support bar as the boundary, draw multiple vertical section lines corresponding to the support bar, and mark each section line in sequence to obtain the baseline diagram; 3) Draw the first wire disc on the reference diagram. Starting from the 2k initial S-bends corresponding to its inner diameter side, draw k connecting lines and k twisting lines respectively, layer by layer, until the drawing of m turns of the wire disc is completed. Draw the wire lead-out head of the wire disc and the twisting S-bend for the transition between wire discs at the specified position to obtain the unfolded diagram of the first wire disc. 4) Draw the second coil on the reference diagram. The winding direction of the second coil is opposite to that of the first coil. Starting from the 2k initial S-bends corresponding to its inner diameter side, draw k connecting lines and k twisting lines respectively. The connecting lines of the first coil are converted into the twisting lines of the second coil, and the twisting lines of the first coil are converted into the connecting lines of the second coil. This process is repeated until the drawing of m turns of the coil is completed. Draw the lead-out head and twisting S-bend of the coil at the specified position to obtain the unfolded diagram of the second coil. 5) In the unfolded diagrams drawn in steps 3) and 4), confirm that the corresponding S-bends of the two coils are in the same position and are in the same layer of turns; after verification, output the unfolded diagram to guide the winding of the entangled coil.

[0011] This technical solution unfolds the circumference of the insulating cylinder into a horizontal baseline, and divides and marks the vertical positions using support bars, resulting in a baseline diagram with a clear coordinate system. This changes the rough representation of traditional schematic diagrams, allowing the position and size of each part of the coil to be precisely defined and measured on the drawing, laying the foundation for subsequent accurate drafting. Using a "layer-by-layer" method, each connecting line and twisting line is drawn on the baseline diagram according to the actual winding sequence and spatial position until all turns are completed. The accumulation process and final distribution of the conductors radially on the wire disc are clearly and completely reproduced on the two-dimensional drawing, allowing the operator to intuitively see the conductor layering at each position. By drawing the first and second wire discs separately, specifying their opposite winding directions and the conversion relationship between connecting lines / twisting lines, and finally confirming that the corresponding twisting S-bends are located in the same position and on the same layer of turns, the radial and circumferential alignment verification of the twisting positions is achieved during the drawing design stage, eliminating potential quality problems caused by "scissor-cut" misalignment from the source. Because the drawings precisely reflect the radial arrangement of the conductors in each span and the positions of all leads and corrections, production personnel can pre-determine whether the conductors will exceed the allowable radial dimensions at specific spans, and whether there is spatial interference in the lead-out paths, thus enabling the early detection and resolution of serious problems that would only surface later or even at the end of production using traditional methods, avoiding rework and material waste. The unfolded diagram generated by this method integrates all necessary information from the baseline and single-pane structure to the relationships between panes, and strictly corresponds to the actual winding process. A single drawing can comprehensively and unambiguously guide the entire winding process, reducing communication costs and operational errors caused by incomplete information or misunderstandings in the drawings, significantly improving the first-time success rate and quality consistency of production.

[0012] As a preferred technique, different wire types or colors are used to distinguish different conductors within the same wire disc.

[0013] By using different line types or colors to distinguish between connecting and twisting lines in the unfolded diagram of the same wire pie, the readability and intuitiveness of the drawings are fundamentally improved. Operators can clearly identify the function and attributes of the wires at a glance, greatly reducing identification errors and confusion during the drawing process. This ensures a quick and accurate understanding of complex wire arrangements when winding or checking according to the drawings, thereby reducing the operational risk of wiring errors caused by misreading the drawings.

[0014] As a preferred technical means: when drawing the first line cake, first use k wires to make the first turn, then place k more wires on the surface of the k wires, and use all N wires to complete the remaining number of turns; in the line cake, the odd-numbered wires counted from the inside out are connecting lines, and the even-numbered wires are twisting lines.

[0015] This technical solution ensures that the generated unfolded diagram is no longer an abstract schematic diagram, but is completely synchronized with and logically consistent with the actual operation steps in the workshop by strictly following the correspondence between this physical winding process and the odd and even numbers of the wires in the drawing rules of the unfolded diagram. This allows the drawing to serve as a direct basis for verifying the correctness of the process execution, and ensures the accuracy of the reverse winding logic from the design source.

[0016] As a preferred technical means: when drawing the second coil, after using N wires to complete all turns except the last turn, cut off the k inner wires and use the k outer wires to make the last turn; in this coil, the odd-numbered wires counted from the inside out are connecting lines, and the even-numbered wires are twisting lines.

[0017] This technical solution adopts the method of drawing a pie chart, which solidifies the process details of "double-layer winding to the final single-layer termination" and the wire properties (odd connected, even connected) into the drawing method. This allows the generated second pie chart to clearly indicate the winding end point and wire transition point, avoiding logical confusion that may occur when winding the main section to the end. It strengthens the guiding role of the drawing on key process turning points and ensures that the pie chart winding result accurately matches the design intent.

[0018] As a preferred technique, in the drawn unfolded diagram, the 2k initial S-bends of the same line disc are located at different gears.

[0019] By stipulating that all initial S-bends of the same coil must be distributed across different sections, this technical solution proactively avoids the concentration of multiple conductors at the same starting point in the drawing rules. This ensures that the starting area on the inner diameter side of the coil in the unfolded drawing will not exhibit abnormal depictions of excessively dense conductors or sudden increases in local radial thickness. This guides the actual winding process to achieve a reasonable and dispersed layout of the conductor starting points, which is beneficial for improving the mechanical strength and uniformity of the electric field distribution at the starting point.

[0020] As a preferred technical approach: In the drawn unfolded diagram, the lead-out head and the S-bend of the same wire disc are alternately set and are successively set at different positions.

[0021] This technical solution optimizes the spatial allocation of functional components in advance through drawing design, minimizing the risk of local structural congestion, insufficient insulation distance, or poor heat dissipation caused by multiple protrusions or correction positions concentrated in a few positions. It also enhances the ability of the unfolded drawing to predict and optimize the rationality of the coil spatial layout, thereby improving the structural reliability and electrical performance of the final product.

[0022] As a preferred technique: when drawing the first and second line cakes, the distance between the same turn of the conductor and the baseline is the same, and the transition position of adjacent turn of the conductor is drawn with an oblique bend transition structure.

[0023] This technical solution ensures that the unfolded diagram accurately reflects the same radial height (i.e., the same layer) of the same turn of wire during winding, placing each turn of wire at a specific height level in the unfolded diagram. This allows for direct and convenient measurement and verification of radial dimensions and the number of wire layers at any location. Furthermore, it provides a unified radial position reference for drawing the first and second wire layers. From a drafting principle perspective, this guarantees that in the final unfolded diagram, the corresponding S-bends and other structures of the first and second wire layers are precisely located on the same radial winding layer, achieving accurate axial alignment and fundamentally eliminating assembly and electrical hazards such as "scissor cuts" caused by winding layer misalignment.

[0024] As a preferred technical means, a marking area is drawn at the end of the conductor. The marking areas at both ends of the same conductor are the same, while the marking areas at both ends of different conductors are different.

[0025] This technical solution uses unique and consistent markings on the ends of the conductors (such as the initial S-bend and the lead-out end) to allow operators to clearly and accurately trace the complete path of each conductor on the unfolded diagram, from the initial S-bend, through all turns and transpositions, to the lead-out or cut-off end. This facilitates understanding complex tangled connections. It eliminates identification errors or wiring confusion that may result from similar conductor appearances, providing a reliable guarantee for winding. Production and inspection personnel can quickly verify the correspondence between the physical conductors and the drawings based on the markings, improving the efficiency and accuracy of process control.

[0026] Beneficial effects: 1. Achieves precise visualization of the coil's radial structure: By fully unfolding each coil conductor along its circumference and dividing it into sections with support bars, the unfolded diagram generated by this invention can clearly and quantitatively display the number of radial conductors and their stacking distribution at each section. This allows designers and manufacturers to directly predict and inspect whether any conductors exceed the allowable radial dimensions in local locations during the drawing stage, fundamentally eliminating potential quality hazards caused by partial discharge or insulation breakdown.

[0027] 2. Ensured the reliability of key process locations: The unfolded diagram clearly marks the precise positions and turn layers of the alignment S-bends and conductor leads. On one hand, it allows for direct verification that the alignment S-bends of adjacent wire coils are in the same position and radially aligned, effectively avoiding the formation of "scissor cuts" and ensuring the mechanical and electrical reliability of the electrical connection. On the other hand, it allows for advance simulation and confirmation of whether the spatial lead-out path of the conductor lead is smooth and unobstructed, avoiding rework and material waste caused by obstructed lead-out during production.

[0028] 3. Provides comprehensive production guidance: Because the unfolded diagram generated by this method strictly simulates the actual winding process (including forward / reverse winding direction, connection and twisting conversion, conductor stacking logic, etc.), the diagram and the physical structure of the final product are highly consistent. A single diagram can contain all the key information from structural layout to process details, providing a unique, accurate, and unambiguous visual instruction for winding operations, significantly reducing the risk of misoperation due to incomplete diagram information or misunderstanding.

[0029] 4. Improved production quality and efficiency from the source: By identifying and resolving potential structural conflicts and process challenges in the design phase, this invention significantly reduces trial and error, rework, and adjustments during production. This not only improves the first-time success rate of coil winding and product consistency but also effectively saves production costs and time, achieving feedforward quality control from design drawings to actual manufacturing.

[0040] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Example 1: This embodiment provides a method for generating a development diagram to guide the winding of tangled coils, such as... Figure 10 As shown, it includes the following steps: S1: Obtain the winding parameters of the entangled coil, including the number of support bars n, the number of parallel wires k for the single coil, and the total number of turns m for the single coil, where the total number of wires used in the single coil is 2k; S2: Unfold the coil insulation cylinder along its circumference to form a horizontal baseline; divide the unfolded circumference into n equal sections using the support bar as the boundary, draw multiple vertical section lines corresponding to the support bar, and mark each section line in sequence to obtain the baseline diagram; S3: Draw the first wire cake on the reference diagram. Starting from the 2k initial S-bends corresponding to its inner diameter side, draw k connecting lines and k twisting lines respectively, layer by layer, until the drawing of m turns of the wire cake is completed. Draw the wire lead-out head of the wire cake and the twisting S-bend for the transition between wire cakes at the specified position to obtain the unfolded diagram of the first wire cake. S4: Draw the second coil on the reference diagram. The winding direction of the second coil is opposite to that of the first coil. Starting from the 2k initial S-bends corresponding to its inner diameter side, draw k connecting lines and k twisting lines respectively. The connecting lines of the first coil are converted into the twisting lines of the second coil, and the twisting lines of the first coil are converted into the connecting lines of the second coil. This process is repeated layer by layer until the drawing of m turns of the coil is completed. Draw the lead-out of the coil and the twisting S-bend at the specified position to obtain the unfolded diagram of the second coil. S5: In the unfolded diagrams drawn in steps S3 and S4, confirm that the corresponding S-bends of the two coils are located in the same position and in the same layer of turns; after verification, output the unfolded diagram to guide the winding of the entangled coil.

[0042] The unfolded diagram formed in step S5 is matched Figure 3 Use it to implement the guidance for winding tangled coils.

[0043] in: Connection: A continuous line is a conductor that connects one tangled unit to the next. Tangled wire: A tangled wire is a conductor used for "tangled connections" within a tangled unit. Twisting position: A tangled position is an S-shaped bend that is bent to complete the series connection of two wires within a "tangled unit".

[0044] To make them easier to distinguish, different wire types or colors can be used to differentiate different conductors within the same wire disc.

[0045] To quickly and accurately verify the radial dimensions and the layer where the S-bend is located, when drawing the first and second line cakes, the distance between the same turn conductor and the baseline is the same, and an oblique bending transition structure is drawn at the transition position of adjacent turn conductors.

[0046] To quickly and accurately identify the beginning and end of each wire, a marking area is drawn at the end of the wire. The marking areas are the same at both ends of the same wire, but the marking areas are different for different wires.

[0047] For clarity, this embodiment uses a specific coil as an example. It consists of two coils (one reversed and one upright).

[0048] Step 1: Obtain basic winding parameters The parameters obtained are as follows: Number of support bars n: In this embodiment, n=10, that is, the circumference of the coil is divided into 10 equal positions.

[0049] Number of parallel conductors in a single-panel circuit, k: In this example, k=1, that is, a single-strand conductor is used in parallel winding.

[0050] Total number of turns m for a single coil: In this example, the total number of turns m for each coil is set to 3 turns (for simplicity of illustration, the actual number of turns may be more).

[0051] Total number of conductors N in a single coil: By definition, N=2k=2, meaning that each coil consists of 2 conductors wound together.

[0052] Step 2: Establish a baseline map Reference Figure 1 To generate a new unfolded diagram of the traditional tangled coil structure shown, a drawing reference must first be established.

[0053] Unfold the coil insulation cylinder 1 along its circumference to form a horizontal baseline. Then, using the positions of the 10 support bars 2 as boundaries, draw 10 vertical dividing lines perpendicular to the baseline, thus dividing the unfolded plane into 10 equal sections. Number these dividing lines from left to right as ⑩, ⑨, ⑧, ⑦, ⑥, ⑤, ④, ③, ②, ①, ⑩, thereby obtaining a reference diagram containing a precise coordinate system.

[0054] Step 3: Draw the first line of the pie chart (inverted pie chart). 1. For example Figure 4 As shown, draw the first conductor (connecting line, line number 8) one turn from the "S" bend (marked as S1) on the inner diameter side.

[0055] 2. For example Figure 5 As shown, draw a second conductor (a twisting line, marked as 4) on the connecting surface from the "S" bend (marked as S2). Draw one turn of the connecting line and the twisting line simultaneously, and transition the connecting line number from 8 to 9.

[0056] 3. For example Figure 6 As shown, the connecting wires and the twisting wires are drawn simultaneously. According to the electrical calculation requirements, draw the required number of remaining turns; in this example, it's one turn. The connecting wire number transitions from 9 to 10, and the twisting wire number transitions from 4 to 5. Draw the conductor lead-out at the required span; in this example, it's in spans ③-④ (marked as X). Also, draw the corresponding "S" bend from the first wire disc to the second wire disc twisting point; in this example, it's in spans ⑤-⑥ (marked as S3). Step 3: Draw the second line pie (the full pie). The second layer is the main layer, and its winding direction is opposite to that of the first layer.

[0057] 1. For example Figure 7 As shown, draw a connecting line 3 and a twisting line 7 at the bottom of the inner diameter side of the second line cake (marked as S1 and S2 respectively). (After transitioning from the first line cake to the second line cake, connecting line 8 is converted into twisting line 7, and twisting line 4 is converted into connecting line 3).

[0058] 2. For example Figure 8 As shown, the connecting line and the twisting line are drawn together again, with the connecting line number changing from 3 to 2 and the twisting line number changing from 7 to 6.

[0059] 3. For example Figure 9 As shown, according to the electrical calculation requirements, continue drawing one turn of connection 2, transitioning the wire number from 2 to 1, and draw the wire to the lead-out position, which in this example is in section ⑦-⑧ (marked as A). At the same time, draw the straightening wire 6 to the straightening position "S" bend, which in this example is in section ⑤-⑥ (marked as S4).

[0060] Step 5: Verification and Output After the drawing is completed, perform key checks on the unfolded diagram: 1. Alignment Verification: Check the alignment S3 of the first disc and the alignment S4 of the second disc. Both are located in positions ⑤-⑥. More importantly, by measuring or observing their radial turns, it can be seen that S3 and S4 are at exactly the same turn height. This verifies that the alignment is precisely aligned in both the radial and axial directions, and will not form a "scissor edge".

[0061] 2. Radial Dimension and Outlet Path Verification: Observe each position in the unfolded diagram (for example, observe any vertical position line) to clearly count the number of radially superimposed conductors at that point, and confirm that the number of radial conductors in all positions does not exceed the design value. At the same time, both the "A" and "X" leads smoothly out from the outermost surface of the coil without any internal structural obstruction.

[0062] Once the verification is successful, the final unfolded drawing can be output. This drawing integrates all information such as datum, precise guide paths, attributes, key process points, and spatial relationships, and can be directly used to guide production.

[0063] By adopting the above technical solution, the number of radial wires in each coil step can be clearly seen, allowing for prediction of whether any wires exceed the radial dimension at each step position, confirmation of whether a scissor-like edge is formed during winding, and verification of whether the lead wire can be successfully led out. In summary, according to the new unfolding diagram drawing rules, the drawings perfectly match actual production, achieving precise guidance from start to finish. This can prevent serious errors such as wires exceeding the radial dimension, inability to lead out leads, and short circuits caused by unclear winding and connection during production, thereby reducing the error rate from the source.

[0064] The above-described method for generating an unfolded diagram to guide the winding of tangled coils is a specific embodiment of the present invention, demonstrating the substantial features and progress of the present invention. Equivalent modifications can be made to this method based on actual usage needs and the inspiration of the present invention are all within the scope of protection of this solution.
