设计并制造了一个储能200 kJ、输出/输入功率75 kW的超导磁体。该装置由两个同轴线圈反串联组成，目的是提高电网中的电能质量，以保持杂散磁场低于0.5 mT的限制。SC线是铜稳定的Nb-Ti绞线。几个铜板被放置在线圈内，以允许线圈内部深处的热量去除，从而允许无冷冻剂冷却和在高AC损耗状态下运行。在液氦温度下进行了几次不同升温速率的实验。本文讨论了这种结构的设计、制造特点和试验结果。
A superconducting magnet with 200 kJ stored energy and 75 kW output/input power has been designed and manufactured. The device, which is aimed to power quality enhancement in electric grid, consists of two coaxial coils, counter-series connected in order to keep the stray field below the limit of 0.5 mT. The SC wire is a copper stabilized Nb-Ti strand. Several copper slabs are placed within the coils in order to permit heat removal deep inside the coil, thus allowing cryogen-free cooling and operation at high AC losses regime. Several tests with different ramp rate have been carried out at the liquid helium temperature. Design and manufacturing characteristics as well as test results are discussed in this paper.
