Способ оценки вихревых токов в сердечниках трансформаторов, отличающийся тем, что, с целью получения количественной оценки степени завихрения магнитного потока для оптимального выбора конструктивных параметров сердечника, по оси распространения магнитного потока располагают одну или несколько последовательно соединяемых обмоток непосредственно внутри сердечника, дополнительно наблюдают форму напряжения на зажимах обмоток, затем по математической модели либо с помощью коллекций диаграмм определяют численные значения характеристик основных параметров трансформатора, по которым судят о степени необходимых конструктивных изменений.A method for evaluating eddy currents in transformer cores, characterized in that, in order to obtain a quantitative assessment of the degree of magnetic flux swirl for an optimal choice of core structural parameters, one or more series-connected windings are placed directly in the core along the magnetic flux axis, and the voltage shape winding clamps, then, according to a mathematical model or using collections of diagrams, determine the numerical values of the characteristics to the main transformer parameters by which to judge the degree of necessary structural changes.
