摘　　要：分析了Rogowski线圈结构参数(如线圈宽度、厚度和中心半径)和电磁参数(如线圈自感、互感和内阻)之间的关系以及它们对线圈动态特性(时域和频域特性)的影响。利用MATLAB软件和等值电路对Rogowski线圈进行了仿真研究。经过实验验证所得出的有关优选Rogowski线圈电磁和结构参数的方法,对于快速设计具有合理结构、最优电磁参数和良好动态特性的Rogowski线圈具有理论指导作用。The relations between dimensions and electromagnetic parameters of the Rogowski coil have been studied as well as their influences on the dynamic performance of the coil(i.e. time-and frequency-domain characteristics). By means of software MATLAB and the equivalent circuit, the methods of optimizing both dimensions and electromagnetic parameters of the coil are proposed, which are verified by experiment and can be as a guide to design a coil with high performance to measure current.
