Calculation and Analysis of Temperature Rise in Transformer Tank Based on Electromagnetic-Thermal Coupling Method

Abstract:

Hot-spot calculation of structure parts in large power transformer has been concerned by transformer designer and researcher. The key is the calculation of leakage magnetic field, loss and temperature rise in structure parts of transformer, belongs to the calculation of the electromagnetic-thermal coupling field. This paper calculate and analysis electromagnetic field and temperature field of a transformer tank using ANSYS analysis software based on electromagnetic fields, heat transfer theory, and the results and the test data are in good agreement; aim at the problem of local overheating, appropriate magnetic shields are used to reduce the stray losses and hot-spot temperature-rise in transformer structure parts. so the calculation method can be applied engineering design.
