摘要
在通常由圆柱形结构的导体组成的高温超导(HTS)电缆应用中,交流损耗一直是障碍商业化进程的关键问题。阐述为了研究非圆形磁场分布对交流损耗的影响,使用BSCCO和YBCO带材制备了两种六边形单层导体。结果表明,在六根导体带材同时通电的模式下,所有导体的交流损耗最小。对于BSCCO和YBCO导体,带材的交流损耗特别依赖于传输模式,圆柱形结构可以明显降低交流损耗。此外,YBCO导体的交流损耗是最低的。
In the application of high temperature superconducting(HTS) cables usually composed of cylindrical conductors,AC loss has always been a key problem hindering the commercialization process.In order to study the effect of non-circular magnetic field distribution on AC loss,two kinds of hexagonal single-layer conductors were prepared with BSCCO and YBCO strips.The results show that the AC loss of all conductors is the smallest when six conductor strips are energized at the same time.For BSCCO and YBCO conductors,the AC loss of the strip is particularly dependent on the transmission mode,and the cylindrical structure can significantly reduce the AC loss.In addition,the AC loss of YBCO conductor is the lowest.
