摘　　要：以电磁场数值方式对Rogowski线圈的分布电容和分布电感进行计算。提出了一种Rogowski线圈分组建模的方法,在满足电小尺寸的前提下对整体模型进行了分组处理,通过电磁场数值结果讨论了单组匝数与组间电磁参数的影响关系,从而建立了线圈简化的低阶等效电路。应用该方法建立模型的35阶等效电路,并进行电路仿真,共需要30 min,而同样条件下,全波电磁场分析大约需要14h。模型样品的仿真以及试验测试结果,验证了笔者建模和分析过程的合理性。In this paper, the distributed capacitance and inductance of Rogowski coil are calculated by numerical method. In order to found the coil＇s equivalent circuit more efficiently, a subdivided modeling method is presented, in which the whole turns of the coil are divided into a series of groups according to the electrical small precondition. Then, the electromagnetic connections among whole turns of the coil are simplified through the discussion of interrelation within several adjacent groups, which directly result in a relative concise and low-order equivalent circuit. It takes 30 minutes to found Rogowski coil＇s equivalent circuit with 35-order, while it takes about 14 hours with full-wave method under the same condition. The method is validated by experiment with impedance analyzer.
