摘要
笔者基于干式带气隙铁心电抗器磁场的有限元法数值仿真结果,对传统解析近似法计算铁心气隙衍射磁通等效导磁面积公式进行了修正,提出了一种改进解析近似法;将提出的方法用于实例计算,并与数值仿真结果比较,表明该方法能提高带气隙铁心电抗器电感计算精度。
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.
