[0035] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0036] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0037] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0038] The main solution of the embodiment of the present application is: obtaining simulation result data of a transformer simulation model, wherein the transformer simulation model is constructed according to the structural parameters and insulation parameters of the transformer, the winding module of the transformer simulation model includes a first winding and a second winding, and the main air path distance between the first winding and the second winding is determined according to the main air path distance between the medium voltage winding and the low voltage winding of the transformer; according to the simulation result data, determining the insulation structure design result of the transformer.

[0039] With the proposal of the "dual carbon" goal, the transformation and upgrading of the energy structure, and the requirements of building a clean, low-carbon, safe and efficient energy system, the power system equipment must also develop in the direction of greener environmental protection, energy conservation and emission reduction. The promotion of the use of vegetable oil transformers also responds to the strategic requirements of the "green grid". At present, the widely used insulating oil in the transformers of the power system is mineral insulating oil, which has a low ignition point and poor biodegradability. It is difficult to meet the manufacturing requirements of electrical equipment with high fire resistance. Leakage will also pollute the surrounding environment and consume a large amount of non-renewable resources such as petroleum. Vegetable insulating oil has the characteristics of high ignition point, biodegradability, and renewability, and has the characteristics of improving the overload capacity of transformers, which can better meet the needs of transformers.

[0040] In the related technology, the development of 500kV vegetable oil transformer is imminent. When developing 500kV vegetable oil transformer, the performance of transformer insulation structure design is usually tested by making transformer prototypes. However, due to the high R&D and manufacturing costs of transformer prototypes, the transformer insulation structure design cost is high. Therefore, how to design the transformer insulation structure and reduce the R&D cost needs to be solved urgently.

[0041] Therefore, the present application provides a solution, by determining the insulation structure design result of the transformer according to the simulation result data of the transformer simulation model. Since it is possible to determine whether the insulation structure design of the transformer meets the requirements based on the insulation structure design result, when the transformer is developed, there is no need to make a transformer prototype for testing, and the performance of the transformer insulation structure design can be tested, thereby saving the R&D cost and manufacturing cost of the transformer prototype, and solving the technical problem of how to design the insulation structure of the transformer and reduce the R&D cost.

[0042] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a transformer insulation structure design device, etc. The following takes the transformer insulation structure design device as an example to illustrate this embodiment and the following embodiments.

[0043] Based on this, the embodiment of the present application provides a transformer insulation structure design method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the transformer insulation structure design method of the present application.

[0044] In this embodiment, the transformer insulation structure design method may include steps S100 to S200:

[0045] Step S100, obtaining simulation result data of a transformer simulation model.

[0046] Among them, the transformer simulation model is constructed according to the structural parameters and insulation parameters of the transformer, the winding module of the transformer simulation model includes a first winding and a second winding, and the main air path distance between the first winding and the second winding is determined according to the main air path distance between the medium voltage winding and the low voltage winding of the transformer.

[0047] Step S200, determining the insulation structure design result of the transformer according to the simulation result data.

[0048] It should be noted that the transformer may include a high voltage winding, a medium voltage winding and a low voltage winding. During the transformer development process, the winding structure and the end insulation structure of the transformer are determined according to the actual design requirements of the transformer, wherein the actual design requirements may include the actual insulation requirements, and the structural parameters and insulation parameters of the transformer may be determined according to the actual design requirements of the transformer.

[0049] It is understandable that in the transformer simulation model, a winding module can be constructed including a first winding and a second winding, which are respectively used to simulate the high-voltage winding and the low-voltage winding of the transformer, and the main air path distance between the first winding and the second winding is set to be the same as the main air path distance between the medium-voltage winding and the low-voltage winding of the transformer, so that the transformer simulation model can also realize the simulation of the medium-voltage winding at the same time. Correspondingly, the end insulation module of the transformer simulation model can be constructed according to the end insulation structure of the medium-voltage winding and the low-voltage winding of the transformer, or the end insulation module of the transformer simulation model can be constructed according to the end insulation structure of the high-voltage winding and the low-voltage winding of the transformer.

[0050] In addition, it is understood that the insulation structure design result can reflect whether the insulation structure design meets the actual insulation requirements of the transformer. Therefore, the developer can judge whether it is necessary to optimize the insulation structure design of the transformer simulation model based on the insulation structure design result.

[0051] In a feasible implementation, step S200 may include steps A210 to A240:

[0052] Step A210, determining whether the simulation result data meets the preset design conditions.

[0053] Step A220: If the simulation result data does not meet the preset design conditions, the transformer simulation model is adjusted to obtain an adjusted simulation model.

[0054] Step A230, using the adjusted simulation model as the transformer simulation model, and returning to execute step S100.

[0055] Step A240, until the simulation result data meets the preset design conditions, the insulation structure design result of the transformer is determined according to the simulation result data.

[0056] It should be noted that the simulation result data can also reflect whether the insulation structure design meets the actual insulation requirements of the transformer. The preset design conditions can be determined according to the actual insulation requirements.

[0057] In the process of simulating using the transformer simulation model, it is possible to determine whether the insulation structure of the currently simulated transformer simulation model meets the actual insulation requirements by judging whether the simulation result data meets the preset design conditions. When it is determined that the insulation structure of the currently simulated transformer simulation model does not meet the actual insulation requirements, the transformer simulation model is adjusted and then the transformer simulation model is repeatedly used for simulation, so that the insulation structure design of the transformer simulation model can be automatically tested and verified through multiple model adjustments and simulations.

[0058] It can be understood that adjusting the transformer simulation model generally involves adjusting the model structure and model parameters of the transformer simulation model.

[0059] In a feasible implementation, before step S100, the transformer insulation structure design method may further include: obtaining structural parameters and insulation parameters; constructing an end insulation module and a winding module according to the structural parameters and the insulation parameters; and constructing a transformer simulation model according to the insulation module and the winding module.

[0060] It should be noted that before executing the transformer insulation structure design of this embodiment, the developer can pre-build a transformer simulation model in the transformer insulation structure design device. Among them, the structural parameters and insulation parameters can be input into the transformer insulation structure design device by the developer. The transformer simulation model can include an end insulation module and a winding module.

[0061] In the specific implementation, after the transformer insulation structure design device receives the structural parameters and insulation parameters input by the developer, the transformer insulation structure design device generates the end insulation module and the winding module accordingly, and then, according to the received instructions, the end insulation module and the winding module are combined to obtain the transformer simulation model. Among them, the overall structure of the transformer simulation model is a single-phase double-winding structure, so that the core of the end insulation module is a single-phase three-column core, and the winding module is combined on the main column of the single-phase three-column core, and the end insulation module and the winding module can be combined, and in the transformer simulation model, they are used to simulate the low-voltage winding and the high-voltage winding from the inside to the outside of the single-phase three-column core.

[0062] In this embodiment, the developer can also set the coil type of the winding module, and the coil type can be set according to the insulation parameters. Preferably, the coil type of the low voltage winding can be spiral, and the coil type of the high voltage winding can be inner screen continuous or spiral.

[0063] In addition, it is understandable that, before simulation, the developer may also set at least one parameter of the hardware material, process treatment scheme and control strategy of the transformer corresponding to the transformer simulation model in the transformer insulation structure design device.

[0064] In a feasible implementation, step S100 may include: using a transformer simulation model to perform electric field simulation and / or wave process simulation to obtain simulation result data.

[0065] In this embodiment, the simulation result data includes electric field intensity data and oscillation potential data.

[0066] It should be noted that the insulation structure design of the transformer simulation model can be tested and verified by using the transformer simulation model for electric field simulation. The insulation structure design of the transformer simulation model can also be tested and verified by using the transformer simulation model for wave process simulation. The insulation structure design of the transformer simulation model can also be tested and verified by using the transformer simulation model for wave process simulation and wave process simulation. At this time, the simulation result data of the winding module of the transformer simulation model can be compared with the actual electric field strength data of the winding structure of the actual transformer and the actual oscillation potential data to analyze the insulation structure design of the transformer simulation model. Among them, the electric field strength data is the average electric field strength. Preferably, when the average electric field strength in the middle of the first winding of the winding module is the same as the actual average electric field strength in the middle of the high-voltage winding of the actual transformer, and the average electric field strength in the middle of the second winding of the winding module is the same as the actual average electric field strength in the middle of the medium-voltage winding of the actual transformer, the simulation result data meets the preset design conditions, indicating that the insulation structure design of the transformer simulation model meets the actual insulation requirements.

[0067] In a feasible implementation, step A220 may include: adjusting the number of turns of the first winding and the oil channel size of the transformer simulation model to obtain an adjusted simulation model.

[0068] It should be noted that this embodiment optimizes the insulation structure design of the transformer simulation model by adjusting the number of turns of the first winding and the size of the oil channel of the transformer simulation model, thereby eliminating the need to adjust the overall model structure and model parameters of the transformer simulation model.

[0069] It can be understood that in the actual simulation process, the transformer simulation model is used to perform electric field simulation and / or wave process simulation to obtain the average electric field strength in the middle of the first winding and the average electric field strength in the middle of the second winding of the transformer simulation model, and to determine whether the average electric field strength in the middle of the first winding is the same as the actual average electric field strength in the middle of the high-voltage winding of the actual transformer, and whether the average electric field strength in the middle of the second winding is the same as the actual average electric field strength in the middle of the medium-voltage winding of the actual transformer; if the average electric field strength in the middle of the first winding is not the same as the actual average electric field strength in the middle of the high-voltage winding of the actual transformer, or the average electric field strength in the middle of the second winding is the same as the actual average electric field strength in the middle of the medium-voltage winding of the actual transformer If the actual average electric field strength in the middle of the winding is different, the number of turns and the oil channel size of the first winding of the transformer simulation model are adjusted, and the simulation is repeated until the average electric field strength in the middle of the first winding of the transformer simulation model is the same as the actual average electric field strength in the middle of the high-voltage winding of the actual transformer, and the average electric field strength in the middle of the second winding of the transformer simulation model is the same as the actual average electric field strength in the middle of the medium-voltage winding of the actual transformer; thereby, by adjusting the number of turns and the oil channel size of the first winding of the transformer simulation model, the transformer simulation model is subjected to wave process simulation calculations and electric field simulation calculations, so that the insulation performance of the equivalent transformer simulation model meets the actual design requirements of the transformer.

[0070] In addition, it is understandable that according to the factory test requirements of the 500kV transformer, the transformer simulation model can be used to carry out factory test simulation to simulate and verify the overall design of the transformer simulation model.

[0071] The present embodiment provides a transformer insulation structure design method, which determines the insulation structure design result of the transformer according to the simulation result data of the transformer simulation model. Since it can be determined whether the insulation structure design of the transformer meets the requirements according to the insulation structure design result, when the transformer is developed, there is no need to make a transformer prototype for testing, and the performance of the transformer insulation structure design can be tested, which saves the research and development cost and manufacturing cost of the transformer prototype, and solves the technical problem of how to design the transformer insulation structure and reduce the research and development cost.

[0072] The present application also provides a transformer insulation structure design device, such as Figure 2 As shown, the transformer insulation structure design device may include:

[0073] An acquisition module 10 is used to acquire simulation result data of a transformer simulation model, wherein the transformer simulation model is constructed according to structural parameters and insulation parameters of the transformer, and a winding module of the transformer simulation model includes a first winding and a second winding, and a main air path distance between the first winding and the second winding is determined according to a main air path distance between a medium voltage winding and a low voltage winding of the transformer;
