摘要
超导储能系统(SMES)强漏磁是影响其安全运行和大量投入使用的关键问题之一。在磁体储能值为1MJ级别的前提下,通过对超导储能磁体参数的计算和有限元分析及仿真的方法,利用两组同轴嵌套型双螺管超导磁体及磁偶极矩的研究方法建立了一个同轴嵌套四螺管型超导储能磁体并对该磁体的漏磁场进行了分析,得出该结构磁体具有极好的降低漏磁的效果。
The strong leakage magnetic field problem of superconducting energy storage system （SMES） is one of the key issues affecting its safe operation and large - scale use. In this paper, under the premise of the magnet energy storage value of 1MJ level, through the calculation of superconducting magnetic energy storage parameters and finite element analysis and simulation methods, a coaxial nested four - solenoid - type superconducting energy - storage magnet was established based on two sets of co- axial nested double - spiral superconducting magnet and magnetic dipoles. Its leakage magnetic field was analysed. It is concluded that the structural magnet has excellent magnetic flux leakage reduction effect.
