摘　　要：提出带抽能线圈并联铁心电抗器的等效电路和电感参数(自感和互感)设计公式,通过对这种特殊并联电抗器三维非线性磁场的有限元分析,准确地计算出电抗器的电感参数以及抽能线圈空载和负载情况下电抗器的伏安特性曲线。对一个试验模型和两台电抗器进行计算表明,应用此方法获得的计算结果与测量结果吻合。It is presented that the equivalent circuit and formulae for calculating inductance parameters (self inductance and mutual inductance) of shunt reactor with auxiliary winding system in the paper. Based on the finite element method, three-dimensional nonlinear magnetic fields in this special shunt reactor are solved in order to calculate the inductance parameters and the Volt-Ampere curves with and without load in auxiliary winding. A test model and two prototype shunt reactors are selected to calculate by this method, and the calculated results are in good agreement with the measured results. This paper provides theory foundation and calculation method in designing shunt reactor with auxiliary winding system.
