摘要
文中对不同频率不同幅值的交变电流下高温超导体YBCO带材的交流传输损耗进行了实验研究。实验在77K下,对Superpower公司生产的SCS4050型号带材采用电测法通过锁相放大器进行了交流损耗值的测量,并将其工作电流为50Hz时的测量结果与Norris矩形模型估算值进行了对比,同时也给出了15Hz到300Hz不同频率下交流损耗测量结果的比较分析。
In this paper, the AC transport current losses of YBCO coated conductor was studied under different currents and different frequencies respectively. The YBCO tape used in this experiment was SCS4050 produced by Superpower Inc. , which was measured in liquid nitrogen （77 K） by a sensitive electrical method with a lock -in amplifier. The measured AC transport current losses results were compared with the Norris formula calculative results when the power frequency equaled to 50 Hz. The measured results in different frequencies which varied from 15Hz to 300Hz were also provided.
