Description

Technical Field

[0001] The present application relates to the technical field of cable structure optimization, and in particular to a cable structure optimization design method, device and computer equipment. Background Art

[0002] In order to reduce production costs, cable manufacturers need to continuously optimize production processes and improve production efficiency. However, although cable manufacturers can reduce production costs in a variety of ways, facing the growing market demand and fluctuations in raw material prices, cable production costs are still under great pressure. For cable operation, the skin effect is common. The skin effect is also known as the skin effect, which exists in alternating current or alternating electromagnetic fields. The skin effect causes the current density to be concentrated on the surface of the wire, resulting in no current passing through the center of the wire, resulting in the problem of waste of the center wire. Therefore, how to reduce the waste of wire resources caused by the skin effect is the current research focus.

[0003] The traditional method of optimizing conductor structure is to reduce the resource cost of the cable by designing hollow conductors. However, hollow conductors are prone to deformation and damage, which reduces the life of the conductors and affects the electrical conductivity of the cable. This results in a large loss of resources in designing the cable conductor structure while ensuring the electrical conductivity. Summary of the invention

[0060] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] The cable structure optimization design method provided in the embodiment of the present application can be applied to the application environment of the cable structure equipment. Among them, the method can be applied to the terminal, can also be applied to the server, can also be applied to the system including the terminal and the server, and is realized through the interaction between the terminal and the server. Among them, the terminal can be but not limited to various personal computers, laptops, etc. Among them, the terminal replaces the structure of the cable conductor without the current transmission part with a filling core, so as to ensure the support effect of the cable conductor, avoid the problem that the cable conductor is easily deformed and damaged, so that the life of the wire is reduced and the conductive performance of the cable is affected. Secondly, the material cost can be greatly reduced by replacing the filling core, thereby reducing the waste of wire resources. Then this scheme simulates the current transmission process of the cable by simulation modeling, so as to locate the position information of the hollow core of the cable, and then constructs a cable core structure model containing each filling core based on this to ensure the simulation accuracy of the cable containing the filling core. Finally, this scheme simulates the current transmission process of each cable core structure model and combines the actual experimental data of the sample cable of the cable core structure model to screen the target cable structure data of the cable, thereby combining simulation with practice, avoiding the impracticality of a single simulation and the problem of simulation data deviation, and improving the accuracy and practicality of the screened target cable structure data, thereby comprehensively improving the resource optimization effect of designing the cable conductor structure while ensuring the conductive performance.

[0062] In an exemplary embodiment, Figure 1As shown, a cable structure optimization design method is provided, which is described by taking the method applied to a terminal as an example, and includes the following steps S101 to S104. Among them:

[0063] Step S101, obtaining cable structure data of the cable, core structure information of each filling core, and physical property information of each filling core, and constructing a cable structure model of the cable based on the cable structure data.

[0064] In this embodiment, the terminal responds to the user's data upload operation to obtain the cable structure data of the target cable that needs cable structure design, the core structure data of each filling core used to fill the hollow core of the cable, and the physical performance information of each filling core. The cable structure data includes the substructure data of each cable structure of the cable, such as Figure 2 As shown, it is the substructure data of the cable structure, wherein each substructure is connected by enclosing covering in a specific order to obtain the cable. Wherein, each cable structure includes but is not limited to an outer sheath layer, a metal shielding layer, a semi-conductive non-woven fabric belt, an insulating shielding layer, an XLPE insulating layer, a conductor shielding layer, a copper conductor, and a filling core. The substructure data of each cable structure includes but is not limited to three-dimensional structure data and structural physical performance data. The physical performance data is the same as the physical performance types included in the physical performance information of the filling core, but the performance data of each physical performance type is different. Wherein, the physical performance types include resistivity, current carrying capacity, conductivity, mechanical strength, thermal conductivity and corrosion resistance, etc. Wherein, the material of each filling core is, for example, hollow aluminum, copper-clad aluminum or polyethylene. Then, the terminal constructs a cable structure model of the cable based on the cable structure data. Wherein, the way to construct the cable structure model of the cable can be modeled by COMSOL Multiphysics software. The specific modeling process will be described in detail later.

[0065] Step S102, simulating the current transmission process in the cable structure model through a preset electric field simulation strategy to obtain the simulated structure data of the cable, and identifying the position information of each hollow core of the cable based on the simulated structure data of the cable.

[0066] In this embodiment, the terminal simulates the current transmission process in the cable structure model through a preset electric field simulation strategy to obtain the simulation structure data of the cable. Among them, the preset power plant simulation strategy is a simulation strategy for electromagnetic and thermal field simulation using COMSOL Multiphysics software. The simulation structure data of the cable is the current transmission of each cable structure in the cable cross section during the simulation of the cable, and the distribution data corresponding to the electromagnetic range. Finally, based on the simulation structure data of the cable, the terminal identifies the position information of each hollow core of the cable. Among them, the hollow core can be the core range at the center of the cable, or the irregular ranges of the cable close to the center. That is, the number of the hollow cores can be one or more. As Figure 3 As shown in the figure, when the ferromagnetic material after the cable is energized contacts the ferromagnetic material without power, the surface of the ferromagnetic material without power will also generate a magnetic field, and the two directions are opposite. At this time, the current appears like a vortex and passes through the magnetic lines of force. In this case, the skin effect is produced. As the frequency increases, the current intensity will also increase, and the current density will be unevenly distributed. As the surface of the conductor goes deeper into the conductor, it is found that the current density distribution gradually decreases; the smaller the frequency, the less obvious the skin effect. In high-voltage and high-frequency wires, people tend to weaken the current density and concentrate it on the surface of the wire. Because when current is supplied to high-voltage wires, the electromotive force on the current surface of the wire is opposite to the electromotive force inside the wire, which will cause the magnetic flux inside the wire to increase as it reaches the center.

[0067] Step S103, based on the core structure information of each filled core, the physical property information of each filled core, and the position information of each hollow core of the cable, adjust the cable structure model to obtain the cable core structure model of each filled core, and simulate the current transmission process of each cable core structure model to obtain the core structure simulation data of each cable core structure model.

[0068] In this embodiment, the terminal adjusts the cable structure model based on the core structure information of each filling core, the physical property information of each filling core, and the position information of each hollow core of the cable, obtains the cable core structure model of each filling core, and simulates the current transmission process of each cable core structure model to obtain the core structure simulation data of each cable core structure model. Among them, the cable core structure model of each filling core is a cable structure model obtained by replacing the conductor at each hollow core position of the cable structure model with each filling core.

[0069] Step S104, collecting core structure experimental data of sample cable structures corresponding to each cable core structure model, and identifying target cable structure data of the cable based on the core structure simulation data of each cable core structure model and the core structure experimental data of each cable core structure model.

[0070] In this embodiment, the terminal collects the core structure experimental data of the sample cable structure corresponding to each cable core structure model, and identifies the target cable structure data of the cable based on the core structure simulation data of each cable core structure model and the core structure experimental data of each cable core structure model. Among them, the terminal obtains the target cable structure data of the cable through two screenings in this step. The first screening is to screen the cable core structure model with better simulation effect through the core structure simulation data. Then, the terminal constructs the sample cable structure based on the core cable structure model, and then instructs the staff to perform the actual current transmission delay to obtain the core structure experimental data of each sample cable structure, and then screens the cable core structure model corresponding to the sample cable structure with a smaller deviation from the cable data of the cable, so as to ensure the target cable structure data after replacing the core, and also ensure the cable transmission performance with the original cable. Thereby, the resource loss of designing the cable conductor structure is reduced while ensuring the conductive performance.

[0071] Based on the above scheme, the structure of the cable conductor without current transmission part is replaced by the filling core, so as to ensure the support effect of the cable conductor, avoid the problem that the cable conductor is easily deformed and damaged, which reduces the life of the wire and affects the conductive performance of the cable. Secondly, the filling core replacement can greatly reduce the material cost, thereby reducing the waste of wire resources. Then this scheme simulates the current transmission process of the cable by simulation modeling, so as to locate the position information of the hollow core of the cable, and then builds a cable core structure model containing each filling core based on this to ensure the simulation accuracy of the cable containing the filling core. Finally, this scheme simulates the current transmission process of each cable core structure model, and combines the actual experimental data of the sample cable of the cable core structure model to screen the target cable structure data of the cable, so as to combine simulation with reality, avoid the non-realistic nature of a single simulation, and the problem of simulation data deviation, and improve the accuracy and practicality of the screened target cable structure data, thereby comprehensively improving the resource optimization effect of designing the cable conductor structure while ensuring the conductive performance.

[0072] Optionally, a cable structure model of the cable is constructed based on the cable structure data, including: splitting the cable structure data into substructure data of each cable structure, and collecting relative position information of each cable structure in a cable database; constructing a substructure model of each cable structure based on the substructure data of each cable structure, and splicing the substructure models of each cable structure based on the relative position information of each cable structure to obtain the cable structure model of the cable.

[0073] In this embodiment, the terminal splits the cable structure data into substructure data of each cable structure, and collects the relative position information of each cable structure in the cable database. The relative position information is the mutual wrapping information of the two cable structures, as well as the wrapping connection information. Then, the terminal constructs a substructure model of each cable structure based on the substructure data of each cable structure, and then, the terminal converts the physical performance information in the substructure data of each cable structure into the model operation parameters of each substructure model through COMSOL Multiphysics software, and adds the model operation parameters of each substructure model to each substructure model.

[0074] Then, the terminal splices the substructure models of each cable structure based on the relative position information of each cable structure to obtain the cable structure model of the cable.

[0075] Based on the above scheme, by splitting the substructure data of each cable structure and constructing the substructure model of each cable structure respectively, the cable structure model of the cable is obtained by structural splicing, thereby improving the accuracy and comprehensiveness of constructing the cable structure model.

[0076] Optionally, through a preset electric field simulation strategy, the process of current transmission is simulated in the cable structure model to obtain simulation structural data of the cable, including: through a preset electric field simulation strategy, the process of current transmission is simulated in the cable structure model to obtain current transmission cross-sectional information in the cable structure model, and based on the current transmission cross-sectional information, the current transmission area in the conductor of the cable and the non-current transmission area in the conductor of the cable are identified; based on the current transmission area and the non-current transmission area, the simulation structural data of the conductor is generated, and the simulation structural data of the conductor is used as the simulation structural data of the cable.

[0077] In this embodiment, the terminal simulates the current transmission process in the cable structure model through a preset electric field simulation strategy, obtains the current transmission cross-sectional information in the cable structure model, and identifies the current transmission area in the conductor of the cable and the non-current transmission area in the conductor of the cable based on the current transmission cross-sectional information. Among them, the current transmission area is the conductor cross-sectional area where current transmission exists and can be actually used for current transmission, and the non-current transmission area is the conductor cross-sectional area where current transmission does not exist and is not actually used for current transmission. That is, the area without current transmission corresponding to the skin effect. Afterwards, the terminal generates the simulation structure data of the conductor based on the current transmission area and the non-current transmission area, and uses the simulation structure data of the conductor as the simulation structure data of the cable.

[0078] Based on the above scheme, by analyzing the current transmission area in the cable conductor and the non-current transmission area in the conductor of the cable, the simulation structure data of the cable is determined, thereby improving the accuracy of identifying the hollow area.

[0079] Optionally, based on the simulation structure data of the cable, the position information of each hollow core of the cable is identified, including: based on the simulation structure data of the cable, identifying each non-current cross-sectional range of each non-current transmission area in the conductor of the cable in the cross-section of the conductor, and the position information of each non-current cross-sectional range; smoothing each non-current cross-sectional range through a range edge smoothing strategy to obtain the core range of each hollow core, and using the position information of each non-current cross-sectional range as the core position point of each hollow core; using the core range of each hollow core and the core position point of each hollow core as the position information of each hollow core of the cable.

[0080] In this embodiment, the terminal identifies the non-current cross-sectional ranges of each non-current transmission area in the conductor of the cable in the cross section of the conductor and the position information of each non-current cross-sectional range based on the simulation structure data of the cable. Then, the terminal smoothes each non-current cross-sectional range through the range edge smoothing strategy to obtain the core range of each hollow core, and uses the position information of each non-current cross-sectional range as the core position point of each hollow core. Among them, the range edge smoothing strategy is a processing method for image edge smoothing, which can be a spatial domain processing method including low-pass filtering, median filtering, and a method of smoothing using low-pass filters such as low-pass trapezoidal filters, low-pass Gaussian filters, low-pass exponential filters, Butterworth low-pass filters, etc. in the frequency domain. Among them, smoothing the edge of the range can reduce data deviation and data abnormality, and improve the accuracy of the identified hollow core range. Finally, the terminal uses the core range of each hollow core and the core position point of each hollow core as the position information of each hollow core of the cable.

[0081] Based on the above scheme, the position information of each hollow core is obtained by identifying the hollow core range corresponding to the non-current cross-sectional range and the position points of the hollow core range, thereby improving the accuracy of the obtained position information of each hollow core.

[0082] Optionally, based on the core structure information of each filling core, the physical property information of each filling core, and the position information of each hollow core of the cable, the cable structure model is adjusted to obtain the cable core structure model of each filling core, including: identifying the structural parameters of each filling core and the simulation operation parameters of each filling core based on the core structure information of each filling core and the physical property information of each filling core; for each filling core, based on the core range of each hollow core of the cable structure model, constructing the filling core model of each hollow core through the structural parameters of the filling core and the simulation operation parameters of the filling core, and filling each filling core model to the core position point of each hollow core to obtain the cable core structure model of the filling core.

[0083] In this embodiment, the terminal identifies the structural parameters of each filling core and the simulation operation parameters of each filling core based on the core structural information of each filling core and the physical performance information of each filling core. The conversion method of each structural parameter and each simulation operation parameter is preset in the COMSOL Multiphysics software. The terminal directly inputs the core structural information of each filling core and the physical performance information of each filling core into the COMSOL Multiphysics software to obtain the structural parameters of each filling core and the simulation operation parameters of each filling core.

[0084] Then, for each filled core, the terminal constructs a filled core model of each hollow core based on the core range of each hollow core in the cable structure model, through the structural parameters of the filled core and the simulation operation parameters of the filled core, and fills each filled core model to the core position point of each hollow core to obtain the cable core structure model of the filled core.

[0085] Based on the above scheme, the efficiency of constructing the cable core structure model of each filling core is improved by converting the structural parameters of each filling core and the simulation operation parameters.

[0086] Optionally, based on the core structure simulation data of each cable core structure model and the core structure experimental data of each cable core structure model, the target cable structure data of the cable is identified, including: for each cable core structure model, based on the core structure simulation data of the cable core structure model, the cable performance value of each cable performance type is identified, and based on the cable performance value of each cable performance type, through a cable performance evaluation strategy, the model score value of the cable core structure model is evaluated; the cable core structure model with a score greater than a threshold is selected as the initial target cable structure model, and based on the core structure experimental data of each initial target cable structure model and the cable structure experimental data of the cable, the performance deviation value between each initial target cable structure model and the cable; the initial target cable structure model corresponding to the minimum performance deviation value is selected as the target cable structure data of the cable.

[0087] In this embodiment, the terminal identifies the cable performance value of each cable performance type based on the core structure simulation data of the cable core structure model for each cable core structure model, and evaluates the model score value of the cable core structure model based on the cable performance value of each cable performance type through the cable performance evaluation strategy. Among them, the cable performance type includes but is not limited to electrical performance (such as resistance, capacitance, insulation withstand voltage, etc.) type, thermal performance (such as thermal conductivity, heat resistance, etc.) type and mechanical performance (such as tensile strength, bending performance, etc.) type, and resource cost saving type, etc., and then, the terminal presets the model score value corresponding to each performance value range of each cable performance type, thereby automatically generating the model score value of each cable core structure model. Improve the efficiency of scoring.

[0088] Then, the terminal screens the cable core structure models with a score greater than the scoring threshold as the initial target cable structure models, and calculates the performance deviation value between each initial target cable structure model and the cable based on the core structure experimental data of each initial target cable structure model and the cable structure experimental data of the cable.
