[0022] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] The present invention provides Figure 1 to Figure 4 A novel transformer lead arrangement structure shown in the figure includes a wiring rack 1, on which a support plate 2 is arranged, and a plurality of support plates 2 are arranged, and the plurality of support plates 2 are evenly distributed, and both ends of the support plate 2 are provided with a second thread groove 12. In actual use, a bolt is used to pass through the second thread groove 12 to install the support plate 2 on the wiring rack 1.

[0025] A pressing plate 3 is provided on the side of the support plate 2, and a positioning assembly is provided between the support plate 2 and the pressing plate 3, and the positioning assembly includes a clamp 4, a trapezoidal groove 5 and a groove 13, the groove 13 is provided on the support plate 2, and the clamp 4 is fixedly connected inside the groove 13. The trapezoidal groove 5 is provided on the pressing plate 3, and the trapezoidal groove 5 and the groove 13 are relatively distributed, and the width of the trapezoidal groove 5 is large at one end close to the support plate 2, and the trapezoidal groove 5 cooperates with the clamp 4.

[0026] The structures such as the clamp 4, the support plate 2 and the pressing plate 3 are all made of insulating materials, such as plastic, etc., and can be adjusted according to specific usage conditions.

[0027] There are multiple groups of positioning components, which are evenly spaced, and a heat dissipation gap 11 is formed between two adjacent groups of positioning components, so that two adjacent leads will not be close to each other, which is convenient for heat dissipation; and the distance between two adjacent groups of positioning components can be adjusted according to specific usage.

[0028] When installing the lead wire, the lead wire is clamped into the inside of the clamp 4 to preliminarily fix the lead wire. After all the lead wires are preliminarily fixed, the pressure plate 3 is then fixed on the support plate 2. During this process, the pressure plate 3 moves toward the support plate 2, and the two ends of the clamp 4 respectively 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 clamp 4 is guided by the inclined walls on both sides of the trapezoidal groove 5, and then the support plate 2 and the pressure plate 3 are connected and fixed, so as to achieve rapid fixation of the lead wire, and there is a certain gap between the leads, which can ensure that each lead wire can have a good heat dissipation effect when the transformer is in working condition, increase the safety of the leads in the transformer during conduction, and ensure the overall stability of the transformer.

[0029] In order to avoid excessive squeezing of the lead wires when the support plate 2 and the pressing plate 3 are connected and fixed, a first thread groove 6 is provided on one side of the pressing plate 3 close to the support plate 2. Two first thread grooves 6 are provided, and the two first thread grooves 6 are respectively distributed at the two ends of the pressing plate 3. The internal threads of the first thread groove 6 are connected with a thread barrel 7. Before installing the pressing plate 3, the operator can rotate the thread barrel 7 to adjust the length of the thread barrel 7 extending from the inside of the first thread groove 6, so as to control the minimum distance between the support plate 2 and the pressing plate 3. In the actual installation process, when the end of the thread barrel 7 away from the first thread groove 6 abuts against the support plate 2, the pressing plate 3 cannot continue to move toward the support plate 2, so as to achieve the effect of limiting, especially for some operators with less experience, to prevent excessive squeezing and improve the convenience of installation operation.

[0030] And a scale can be set on the outside of the threaded barrel 7 to facilitate adjustment by the operator.

[0031] In order to achieve the connection and fixation between the support plate 2 and the pressure plate 3, a circular groove 8 is opened 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 thread groove 6. Two circular grooves 8 are provided, and the circular grooves 8 are connected with the corresponding first thread grooves 6. A screw 9 is arranged inside the circular groove 8, and the screw 9 passes through the circular groove 8, the first thread groove 6 and the threaded barrel 7 in sequence. A threaded hole 10 cooperating with the screw 9 is opened on the support plate 2.

[0032] When the support plate 2 is connected and fixed with the pressing plate 3, the operator sequentially passes the screw 9 through the circular groove 8, the first thread groove 6 and the threaded barrel 7, and docks with the corresponding threaded hole 10, and then rotates the screw 9. When the end of the threaded barrel 7 away from the first thread groove 6 abuts against the support plate 2, the screw 9 cannot be rotated further, and the connection and fixation between the support plate 2 and the pressing plate 3 is completed.

[0033] Example 2

[0034] A novel transformer lead arrangement method, the method also includes collecting a position image of the transformer lead; judging whether the position of the lead meets the lead design requirements based on the position image of the transformer lead; and obtaining early warning information when the position of the lead does not meet the lead design requirements.

[0035] Specifically, the present embodiment discloses a post-implementation early warning detection method. Before implementation, the internal leads of the transformer can be digitally modeled and accurately arranged, or images of the old transformer can be captured to re-model the transformer.

[0036] The layout of the leads is analyzed through big data, and automatic warnings are issued for areas that do not meet the design requirements in parts that cannot be clearly indicated in traditional design methods. This not only improves the safety and accuracy of the transformer lead design, but also provides a new lead design method for transformer designers, avoiding the design risks brought by traditional lead design methods, reducing lead design time, and clearly guiding workshop assembly through partial magnified views, improving production efficiency and transformer quality.

[0037] The patent of this invention changes the problem in the traditional lead design method, which cannot intuitively and accurately reflect the internal lead layout structure of the transformer. Through intelligent three-dimensional transformer design software, a digital model is established in proportion, and then the electrical safety distance between each lead under different working conditions is set. The insulation safety distance of each lead in the design model is calculated separately, and the design method whether there is a situation below the safety distance is quickly determined. When there is a situation where the set safety distance is not met between the leads, the software will automatically start the error warning, perform error analysis on all problematic leads one by one, and then display the coordinate points below the safety distance, and summarize the data to generate a report to guide the transformer engineer to make design corrections. After the engineer makes design corrections to all alarm problem points, verification analysis can be performed again. If it is not met, the above warning is repeated until all lead arrangements fully meet the design requirements.

[0038] An example of the automatic warning detection steps is as follows: the safety distance is set to 20mm, and 19 objects are tested for safety. Through the analysis results of the browser, it is detected that the distance between 11 objects is less than the set minimum safety distance of 20mm, which does not meet the design requirements. The selected content is the interference point position. Click the interference point, and you can see the two leads that do not meet the safety distance in the model (highlighted), and the software will automatically zoom to the point where the safety distance is not met. Engineers can make changes to the alarm point to make the interference objects meet the design requirements. After the changes are completed, engineers can re-execute the corresponding operations. After the detection is correct, the lead design meets the design requirements and the construction drawings are output.

[0039] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
