Description

Technical Field

[0001] This invention belongs to the field of transformer technology, specifically relating to a novel transformer lead arrangement structure and its design method. Background Technology

[0002] Transformers are a crucial component of the power system, vital to the safety and stability of the power grid. Faults in transformers can not only cause power outages but also disrupt economic development and people's daily lives. With the rapid development of the power system, transformer voltage levels and capacities are constantly increasing, placing greater demands on the safe and stable operation of transformers.

[0003] As a nonlinear, time-varying electromechanical device with strong coupling of multiple physical fields, the transformer requires meticulous arrangement of its internal leads to ensure overall safety and stability.

[0004] Currently, when routing transformer leads, multiple leads are usually arranged close together and clamped together. The close proximity of two adjacent leads can easily lead to poor heat dissipation when the leads are conducting electricity. Summary of the Invention

[0005] The purpose of this invention is to address the problem that current transformer lead routing typically employs a structure where multiple leads are tightly packed side-by-side, leading to poor heat dissipation during conductive states. This invention provides a novel transformer lead arrangement structure and its design method that is simple in structure and rationally designed.

[0006] The first aspect of the present invention provides a novel transformer lead arrangement structure, including a wiring frame, a support plate disposed on the wiring frame, a pressure plate disposed on the side of the support plate, and a positioning component disposed between the support plate and the pressure plate. The positioning component includes a clamp, a trapezoidal groove, and a recess. The recess is formed on the support plate, the clamp is fixedly connected to the inside of the recess, and the trapezoidal groove is formed on the pressure plate. The trapezoidal groove and the recess are distributed opposite to each other. The end of the trapezoidal groove closer to the support plate is wider, and the trapezoidal groove cooperates with the clamp.

[0007] Preferably, multiple support plates are provided, and the multiple support plates are evenly distributed.

[0008] Preferably, the positioning components are provided in multiple sets, and the multiple sets of positioning components are distributed at equal distances.

[0009] Preferably, a heat dissipation gap is formed between two adjacent sets of positioning components.

[0010] Preferably, the pressure plate has a first threaded groove on the side near the support plate. There are two first threaded grooves, which are respectively distributed at both ends of the pressure plate. A threaded cylinder is threadedly connected to the inside of the first threaded groove.

[0011] Preferably, the pressure plate has a circular groove on the side facing away from the support plate. There are two circular grooves, and the circular grooves are connected to the corresponding first threaded grooves. A screw is installed inside the circular groove, and the screw passes through the circular groove, the first threaded groove and the threaded cylinder in sequence. The support plate has a threaded hole that mates with the screw.

[0012] Preferably, the support plate has a second threaded groove at both ends.

[0013] A second aspect of the present invention provides a novel method for arranging transformer leads, the method further comprising: acquiring position images of the transformer leads; determining whether the position of the leads meets the lead design requirements based on the position images; and obtaining early warning information when the position of the leads does not meet the lead design requirements.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention achieves rapid fixation of the leads by setting up structures such as support plates, pressure plates and positioning components, and there is a certain gap between the leads, which can ensure that each lead has a good heat dissipation effect when the transformer is in operation, which increases the safety of the lead conduction process in the transformer and ensures the overall stability of the transformer.

[0016] 2. By setting the first threaded groove and threaded cylinder, the minimum distance between the support plate and the pressure plate is controlled to achieve the limiting effect, prevent excessive squeezing, and improve the convenience of installation and operation.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] This invention provides, for example Figures 1-4 The diagram illustrates a novel transformer lead arrangement structure, comprising a wiring frame 1, on which a support plate 2 is mounted. Multiple support plates 2 are evenly distributed, and each support plate 2 has a second threaded groove 12 at both ends. In practical use, bolts are passed through the second threaded grooves 12 to mount the support plate 2 onto the wiring frame 1.

[0025] A pressure plate 3 is provided on the side of the support plate 2. A positioning component is provided between the support plate 2 and the pressure plate 3. The positioning component includes a clamp 4, a trapezoidal groove 5, and a recess 13. The recess 13 is formed on the support plate 2, and the clamp 4 is fixedly connected inside the recess 13. The trapezoidal groove 5 is formed on the pressure plate 3. The trapezoidal groove 5 and the recess 13 are distributed opposite to each other. The end of the trapezoidal groove 5 closer to the support plate 2 is wider, and the trapezoidal groove 5 cooperates with the clamp 4.

[0026] The clip 4, support plate 2, and pressure plate 3 are all made of insulating materials, such as plastic, and can be adjusted according to specific usage.

[0027] The positioning components are arranged in multiple sets, which are distributed at equal distances. A heat dissipation gap 11 is formed between two adjacent sets of positioning components, so that two adjacent leads will not be in close contact, which facilitates heat dissipation. The distance between two adjacent sets of positioning components can be adjusted according to the specific application.

[0028] When installing the leads, the leads are inserted into the clamps 4 for initial fixation. After all leads are initially fixed, the pressure plate 3 is then fixed onto the support plate 2. During this process, the pressure plate 3 moves toward the support plate 2, and the two ends of the clamps 4 abut against the inclined walls on both sides of the trapezoidal groove 5. As the pressure plate 3 gradually moves toward the support plate 2, the clamps 4 retract under the guidance of the inclined walls on both sides of the trapezoidal groove 5. Then, the support plate 2 and the pressure plate 3 are connected and fixed, achieving rapid fixation of the leads. The leads have a certain gap, which ensures that each lead has good heat dissipation during transformer operation, increases the safety of the leads during conduction, and ensures the overall stability of the transformer.

[0029] To prevent excessive compression of the lead wire during the connection and fixing of the support plate 2 and the pressure plate 3, the pressure plate 3 has a first threaded groove 6 on the side near the support plate 2. There are two first threaded grooves 6, located at opposite ends of the pressure plate 3. A threaded cylinder 7 is threaded into the interior of each first threaded groove 6. Before installing the pressure plate 3, the operator can rotate the threaded cylinder 7 to adjust its length extending from the inside of the first threaded groove 6, thereby controlling the minimum distance between the support plate 2 and the pressure plate 3. During actual installation, when the end of the threaded cylinder 7 furthest from the first threaded groove 6 abuts against the support plate 2, the pressure plate 3 cannot continue to move towards the support plate 2, achieving a limiting effect. This is especially beneficial for less experienced operators, preventing excessive compression and improving the ease of installation.

[0030] Furthermore, a scale can be set on the outside of the threaded cylinder 7 for easy adjustment by the operator.

[0031] To achieve the connection and fixation between the support plate 2 and the pressure plate 3, a circular groove 8 is provided on the side of the pressure plate 3 facing away from the support plate 2, and the inner diameter of the circular groove 8 is larger than the inner diameter of the first threaded groove 6. There are two circular grooves 8, and the circular grooves 8 are connected to the corresponding first threaded grooves 6. A screw 9 is provided inside the circular groove 8, and the screw 9 passes through the circular groove 8, the first threaded groove 6 and the threaded cylinder 7 in sequence. A threaded hole 10 that mates with the screw 9 is provided on the support plate 2.

[0032] When the support plate 2 is connected and fixed to the pressure plate 3, the operator passes the screw 9 through the circular groove 8, the first threaded groove 6 and the threaded cylinder 7 in sequence, and aligns it with the corresponding threaded hole 10. Then, the operator rotates the screw 9. When the end of the threaded cylinder 7 away from the first threaded groove 6 abuts against the support plate 2, the screw 9 can no longer be rotated, thus completing the connection and fixation between the support plate 2 and the pressure plate 3.

[0033] Example 2

[0034] A novel method for arranging transformer leads includes: acquiring position images of the transformer leads; determining whether the position of the leads meets the lead design requirements based on the position images; and obtaining early warning information when the position of the leads does not meet the lead design requirements.

[0035] Specifically, this embodiment discloses a post-implementation early warning detection method. Before implementation, the internal leads of the transformer can be digitally modeled and precisely arranged, or images of old transformers can be collected to remodel them.

[0036] By analyzing lead layout schemes using big data, and automatically issuing warnings for areas that do not meet design requirements and are not clearly indicated in traditional design methods, this approach not only improves the safety and accuracy of transformer lead design but also provides transformer designers with a new lead design method. It avoids design pitfalls associated with traditional lead design methods, reduces lead design time, and allows for clear guidance of workshop assembly through magnified views, thereby improving production efficiency and transformer quality.

[0037] This invention patent addresses a problem in traditional lead design methods that fail to accurately and intuitively represent the internal lead arrangement of a transformer. It utilizes intelligent 3D transformer design software to create a proportional digital model. By setting electrical safety distances between leads under different operating conditions, the software calculates the insulation safety distances for each lead in the design model and quickly identifies any designs that fall below the safety distance. When a lead fails to meet the set safety distance, the software automatically triggers an error warning, analyzes each problematic lead individually, displays the coordinates of points below the safety distance, and generates a report to guide transformer engineers in design corrections. After engineers correct all alarmed issues, they can perform another verification analysis. If the requirements are still not met, the warning process repeats until all lead arrangements fully meet the design requirements.

[0038] Example of automatic early warning detection steps: A safety distance of 20mm is set, and safety checks are performed on 19 objects. Analysis by the browser reveals 11 locations where the distance between objects is less than the set minimum safety distance of 20mm, failing to meet design requirements. These are the interference points. Clicking on an interference point will display the two interfering leads (highlighted) in the model, and the software will automatically zoom to the location of the non-compliance. Engineers can modify the alarm points to ensure the interfering objects meet design requirements. After modification, engineers can re-execute the corresponding operations. Once the detection is successful, the lead design meets design requirements, and construction drawings are output.

[0039] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
