Bi-2223复合导体直流磁场下自场损耗热稳定性分析

摘要

对于一种Bi-2223的复合导体,利用ANSYS软件,我们分析了在直流磁场下励磁过程中,自场损耗对复合导体热稳定性的影响；然后假定Bi-2223超导带内不同的损耗值,通过计算,确定了达到超导带分流温度的最小损耗值.%For one kind of Bi -2223 composite conductor, we analyzed the influence of self-field loss subject to DC magnetic field on the thermal stability of this composite conductor during charging period with ANSYS software. Assuming different losses in Bi -2223 tapes, we found the minimum loss which caused superconducting tape to reach its current sharing temperature.
