摘　　要：以Rogowski线圈的电流测量原理为基础,建立了骨架截面为圆形和矩形时线圈结构参数影响其电磁感应能力的相关数学模型,并进行了仿真研究。结果表明,圆形线圈的互感系数相对误差较小,有利于获取更准确的电流值;增大线圈的骨架直径和中心直径,能使线圈的感应信号增强,但必须控制两者的比例值。最后,提出了线圈结构参数的选用方法,并结合实例对研究结果的有效性进行了验证,为快速、合理地选用Rogowski线圈提供有力的指导。On the basis of current measuring principle of Rogowski coil, relevant mathematical models are set up for the impact of coil structure parameters on electromagnetic induction ability with the frame section as circular and rec-tangular respectively.Simulation results show that relative error of circular coil mutual inductance is small, which is helpful for obtaining accurate current values.Moreover, increasing the frame diameter and center diameter of coil could enhance the coil induction signal.The ratio values of them, however, must be under controlled.Finally, a structure parameters selection method of Rogowski coil is put forward, and the effectiveness has been verified combi-ning with instances, which will provide powerful guidance for selecting Rogowski coil rapidly and reasonably.
