Research on magnetic field and temperature field of air core power reactor

The 2D and 3D magnetic field of air core power reactor have been analyzed in this paper. Field-circuit coupled FEM model is established to calculate 2D magnetic field and winding currents. The calculated currents have been taken as excitation to calculate 3D magnetic field. The resistance losses and eddy current losses have been computed based on magnetic field analysis. Furthermore, taking all losses as thermal sources, 3D temperature field of air core reactor has been analyzed and discussed.
