摘要
为精确旋转磁场强度的测量结果,文中利用有限元仿真软件建立三维电磁场模型,比较了两种主要磁场的测量方法,即H线圈和罗氏线圈的测量误差,得出H线圈测量结果更加准确的结论并对此作出解释。在此基础上,研究了H线圈的测量距离与测量误差的关系,并将研究结果应用至试验过程中,减小了实际测量结果的误差。
In order to accurately measure the rotating magnetic field strength,the finite element simulation software has been applied to build 3D electromagnetic field model.Error of two major methods about measuring magnetic fields H coils and Rogowski Chattock coil has been studied.A conclusion that measuring results using H coils are more accurate has been made and explained.Based on that,the relationship of test error with the distance between H coil and surface of sheet has been studied,and the results have been used to the experiments.The error of experimental measurement has been reduced finally.
