The term "and/or" refers to and includes any and all possible combinations of one or more of the associated listed items.
Referring to fig. 1, an embodiment of the present disclosure provides a method for evaluating parameters of a transformer wire. As shown in fig. 1, the method for evaluating the parameters of the transformer wires includes steps S10 to S30. The method comprises the following steps:
s10, acquiring original data of the transformer to be detected, and performing completion processing on a data missing part of the original data.
In this step, the original data of the transformer to be tested is obtained first. The original data comprises basic parameters of the transformer to be tested, including the model, rated capacity, transformation ratio, phase number and the like of the transformer to be tested, and further comprises transformer evaluation data in a fixed numerical value range, namely a lead length range, an insulation thickness range and the like.
After the original data of the transformer to be detected is acquired, the integrity of the data needs to be judged, and then selective optimal data solution filling and completion are carried out on the missing part of the original data under the condition that the data is incomplete, so that a processed completion result is obtained.
And S20, comparing the completed data with the data of the database to obtain the data quantity of the wire parameters meeting the preset conditions.
In this step, the completion result obtained in step S10 is input to a database for data comparison and analysis. It can be understood that reliable data capable of ensuring safe operation of the transformer is stored in the database, and the supplemented transformer input data is compared with the data in the database, so that the conductor parameters meeting the preset conditions can be screened out and obtained. The preset conditions can also ensure reliable data of safe operation of the transformer, and can be set according to actual conditions without any limitation.
And S30, when the data volume of the lead parameters is smaller than a preset threshold value, calculating the short-circuit-resistant lead parameters of the transformer according to the completed data.
In the last step, data of the lead parameters meeting the preset conditions are screened out after comparison with the database, in the step, the number of the partial data needs to be counted first, when the data quantity of the lead parameters is smaller than a preset threshold value, the problem that short circuit and the like possibly exist in the operation of the transformer to be tested is proved, therefore, the lead parameters of the transformer for resisting the short circuit need to be calculated according to the completed data, and finally the partial lead parameters are output to guide workers to design the transformer. The preset threshold value may also be set manually according to actual conditions, and is not limited herein. In one specific embodiment, the conductor parameters of the transformer meeting the short circuit resistance condition are calculated mainly according to the equipment parameters, the stress deformation, the displacement and the service life loss of the transformer.
Therefore, the embodiment can quickly analyze the operation condition of the transformer by adopting different leads so as to analyze the short-circuit fault process. Starting from the aspects of the material and specification selection of the transformer winding wire, the complexity of analyzing and evaluating the transformer by designers is reduced, and the reliability of the transformer design is improved.
Referring to fig. 2, in an embodiment, the method for evaluating the transformer lead parameters further includes:
s40, outputting all wire parameter data when the data quantity of the wire parameters is larger than or equal to a preset threshold value; the wire parameter data is used in a transformer design process.
Step S30 shows that the data amount of the lead parameter screened by the database is smaller than the preset threshold, the short-circuit resisting parameter needs to be calculated, and the calculated parameter is referred to by the designer. However, in the application, there is another case that the data amount of the wire parameter is greater than or equal to the preset threshold, then the calculation of the anti-short circuit parameter can be directly skipped at this time, and the wire parameter of the part is directly output for the designer to refer to.
In conclusion, the method provided by the embodiment of the application can evaluate the performance of the transformer winding wire, and give a reasonable wire material specification combination which is comprehensive and accurate; the method can ensure the rapidity, the reliability and the result selectivity of analysis, is a reasonable selection judgment basis for the specification of the winding lead material, is suitable for most types of transformers, and has accurate test results, simplicity and easy operation; and the analysis cost is low, the use of computer resources is reduced, the calculation time is shortened, and the safe and stable operation of the transformer is ensured.
In a specific embodiment, based on the method for evaluating the parameters of the transformer conductor provided in the above embodiment, a set of application programs is correspondingly provided. The flow chart of the application program implementation is shown in fig. 3: firstly, a worker opens the transformer wire parameter evaluation software (fig. 3 is intelligent evaluation software of winding wire materials and specifications thereof), then records original data of a transformer to be evaluated and inputs the original data into a completion module to complete the data, the completed data can obtain wire parameters meeting preset conditions through a database comparison module, then the result screening module judges whether the data quantity of the wire parameters output by the database comparison module reaches preset values or not, when the data quantity reaches preset threshold values, the conditions are considered to be met, and at the moment, the wire parameter data results can be directly displayed on a display interface. If the preset threshold value is not reached, the data are input into the rapid short-circuit resisting calculation module if the preset condition is not met, and finally the calculated lead parameters capable of resisting the short circuit of the transformer are displayed. The main interface of the intelligent evaluation software for the winding wire material and the specification thereof is shown in fig. 4, and the basic data, evaluation conditions and result display interface of the operation evaluation are respectively shown in fig. 5, 6 and 7.

And the fast short-circuit resisting calculation module 03 is configured to calculate a short-circuit resisting wire parameter of the transformer according to the completed data when the data amount of the wire parameter is smaller than a preset threshold.
It should be noted that, the comparison and analysis module 02 analyzes the data amount of the result output by the database comparison module, and when it is determined that the database does not have suitable transformer wire parameter data, that is, the data amount is smaller than the preset threshold value, the data is input to the fast short-circuit-resistant calculation module 03 for analysis.
The fast short circuit resisting calculation module 03 performs fast analysis on the completion data output by the data completion module, calculates and analyzes transformer operation conditions of various different wires under the condition that the calculation and analysis meet the limit conditions, obtains wire parameter data meeting the safe operation conditions, and outputs the result.
In one embodiment, the fast short-circuit-resistance calculating module 03 is further configured to calculate the conductor parameters of the transformer meeting the short-circuit-resistance condition according to the equipment parameters, the stress deformation, the displacement and the life loss of the transformer.

Specifically, the result output module 04 is configured to output all wire parameter data when the data amount of the wire parameter is greater than or equal to a preset threshold; the wire parameter data is used in a transformer design process.
It can be understood that the comparison analysis module 02 analyzes the data amount of the result output by the database comparison module, and performs the analysis of the fast short-circuit-resistant calculation module 03 when the database does not have suitable transformer wire parameter data; if the output result of the database comparison module meets the requirement of the data volume, the fast short-circuit-resistant calculation module 03 can be directly skipped over to output the result.
