单螺管型超导储能磁体周围的杂散磁场随着其储能量的增加而急剧增长.对杂散磁场进行屏蔽是保护外围仪器设备和工作人员人身安全的必要手段.对储能量为2.5 MJ的单螺管磁体的杂散磁场进行了仿真分析与主动屏蔽.分析了同轴串联式与单圈嵌套式屏蔽方式的磁体结构、屏蔽原理和屏蔽效果,并从线材用量、安全距离以及屏蔽效果等方面进行了对比分析.
Abstract：The stray field of single solenoid SMES magnet increased sharply with the addition of energy storage. It was essential to shield the stray field for the protection of outer instruments,equipment and the safety of staffs. The stray field and shielding methods of 2. 5 MJ single solenoid magnet were analyzed and simulated. The differences of magnet structures,shielding principle and shielding effect between the shielding with axially displaced coils and the shielding with single coaxial nested coils were simultaneously analyzed. Ultimately,the two shielding methods in respects of material amount,covers and shielding effect were compared.
