电磁热耦合模型在通风干式变压器中的运用
Application of Electromagnetic Thermal Coupling Model on Ventilated Dry-type Power Transformer
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.
