THE SUPERCONDUCTING FAULT CURRENT LIMITING CHARACTERISTICS TEST AND NUMERICAL ANALYSIS OF A Bi-2212 ELEMENT

Keywords： AC loss , fault current limiting characteristics , local temperature distribution , superconducting fault current limiting element

Bi-2212元件(Bi-2212 monofilar bulk element)是开发24KV/630A超导限流器(SFCL)的元件之一.本研究从实验和理论上探讨了Bi-2212元件的直流伏安特性、交流损耗特性、限流特性和局部温度分布.结果发现Bi-2212元件的临界电流增加了3.3倍而工作温度从77K降低到65K.尽管Bi-2212导体是线圈排列,但是其交流损耗的测量值与Norris方程的计算结果相似,温度都在77K和65K之间.故障期间每段温度的测量值与数值分析的结果一致.
