随着高储能量的高温超导储能磁体在电力系统中的应用日益广泛,对高储能量磁体周围漏磁场的屏蔽愈加重要.本文利用有限元仿真软件ANSYS分析了储能量为2.5MJ的高温超导磁体周围的漏磁场分布,并对其进行同轴嵌套式主动屏蔽.根据理论计算确定屏蔽磁体的几何尺寸和应加载的电流密度,并对四个不同几何参数的嵌套式屏蔽磁体进行仿真分析,最终确定了效果较好的屏蔽方案.
With the increasing use of high-energy storage HTS magnets in power systems, the shielding of the leakage magnetic field around high-energy storage magnets becomes more and more important.In this paper, the finite element simulation software ANSYS is used to analyze the high temperature The magnetic field distribution around the superconducting magnet and its coaxial nested active shielding.According to the theoretical calculation to determine the geometry of the shielding magnet and the current density should be loaded, and four different geometric parameters of the nested shielding magnet Carry on the simulation analysis, and finally determine the better shielding scheme.
