Numerical Analysis of Magnetic Field and Inductance of Air Core Reactor Winding

空心电抗器的漏磁场对周边设备的温升以及工作人员安全有很大的影响,本文采用数值解析算法和有限元法分析了空心电抗器绕组的电磁参数,得出了绕组内部和外部磁通密度分布结果;并用数值分析编写了电感计算程序;两种方法结果完全一致,对于空心电抗器尤其是需要三维仿真的工程计算具有参考价值。

The leakage magnetic field of air core reactor has a great impact on the temperature rise of peripheral equipment and the safety of staff.In this paper,the electromagnetic parameters of air core reactor winding are analyzed by using numerical analysis algorithm and finite element method,and the distribution results of magnetic density inside and outside the winding are obtained.The results of the two methods are in good agreement with each other,which has reference value for the air core reactor,especially the three-dimensional engineering simulation calculation.
