| 摘 要： | 高温超导带材在磁场中传输交变电流时,将受到电磁力的作用而产生机械振动,振动对带材的交流损耗将产生影响.本文讨论了振动情况下交流损耗的测量方法,在平行于带面的直流磁场下,测量了Bi-2223/Ag高温超导带材在不同振动情况下的交流损耗.结果显示:当传输电流频率偏离样品的共振频率时,振动对带材的交流损耗影响不大;只有当电流频率在共振频率附近时,样品产生剧烈振动,交流损耗才有明显的增加;另外,带材振动时的交流损耗随频率变化曲线的斜率比不振动时略有增加.

| Abstract: | The high temperature superconducting tape will vibrate due to magnetic force when it carrying AC current in applied magnetic field. As a result,the vibration may affect AC losses of the tapes. In this work,the effect of vibration on AC losses was discussed. AC losses of Bi-2223 /Ag reinforced tapes were measured in different vibration situation in parallel DC magnetic field. According to the results,there were slight effects of the vibration on the AC losses of HTS tapes when the frequency of transport curr... |
