摘　　要：罗氏线圈在电力系统测量中有着广泛的应用,作为电流互感器,有很多因素影响罗氏线圈互感器的精度。文章运用基于有限元法的Ansoft软件,选取影响罗氏线圈互感系数的温度与导线位置2个参数进行仿真计算,并与理论值进行分析比较。仿真结果验证了罗氏线圈互感器的互感系数与温度成正比结论的正确性,表明了导线位置的变化会影响互感系数,该结论与传统的理论计算结果不同。Rogowski coil has been widely applied in the measurement of power system. There are many factors that affect the accuracy of Rogowski coil current transducer. In this paper, the simulation on the two factors that affect Rogowski coil mutual inductance, namely the temperature and the position of the wire, was conducted by using the finite element method based Ansoft software. The results were analyzed and compared with the theoretical ones. The results verify that the mutual inductance of Rogowski coil is proportional to the temperature of the environment. The results also show that the position of the wire affects the mutual inductance, which is not in accordance with the traditional theo- retical result.
