电磁热耦合模型在通风干式变压器中的运用

摘要

建立了通风干式变压器绕组温度场的二维电磁热耦合数学模型,并由此计算出变压器箔式绕组因非均匀涡流产生的温度分布,仿真结果与实验数据表明:基于二维电磁热耦合数学计算模型的分析方法是正确、合理、可靠的,为研究干式变压器的温度特性提供了方便.%A two-dimensional electromagnetic coupling model of ventilated dry-type transformer winding hot is founnded, which can calculate the transformer foil windings due to eddy current non-uniformity of the heat generated. Simulation results and experimental data show that the coupled electromagnetic thermal analysis based on two-dimensional mathematical model is correct, reasonable and reliable for the study of the temperature characteristics of dry-type transformers.
