Development of conduction-cold high temperature superconducting magnet for high power microwave devices
为了利于高功率微波系统的紧凑化和小型化,降低系统能耗,对产生引导磁场的超导磁体系统进行了研究设计.超导磁体使用稀土钡铜氧化物线饼组成.低温系统采用 4台小型风冷式斯特林制冷机对超导磁体冷却.为了适用于车载环境并降低漏热,采用了一种非金属材料的新型锥体结构作为磁体的承载结构,并通过仿真分析了一般的车载环境下的磁体结构承载情况.整个高温超导磁体工作温区为 40～50 K,达到目标场时的通电电流为 77.49 A,均匀区场强达到 4T.整个系统能耗较传统技术降低 80%.通过实验测试出高温超导磁体的温度运行上限为 48.9 K.
To compact and miniaturize the high-power microwave system and reduce the energy consumption of the magnet system,the superconducting magnet which generates the guiding magnetic field is studied and designed.The magnet is composed of rare earth barium copper oxide coil pancakes.In the cryogenic system,four air-cooled Stirling cryocoolers are used to cool down the superconducting magnet.To be suitable for vehicle environments and reduce the heat leakage,a new cone bearing structure of non-metallic material is adopted as the load-bearing structure of the magnet.And the load-bearing situation of the magnet structure under the general vehicle environment is analyzed by the simulation.The superconducting magnetic field in the uniform region reaches 4 T when the current is 77.49 A in the range of 40-50 K.The energy consumption of the whole system is 80%lower than the traditional technology.The experimental results show that the upper temperature limit of the high temperature superconducting magnet(HTS)is 48.9 K.
