| Abstract: | Based on the numerical simulation result of the magnetic field distribution of dry-type gapped-iron core reactor by finite element method,the equivalent cross-sectional area formula for iron gap diffraction magnetic flux is modified and a new improved analytical approximation method is proposed for calculating the principle reactance.The proposed method is applied to an example and the results show the proposed method to be more accuracy. |
