| 摘 要： | 高温超导变压器的漏磁场降低绕组中的临界电流并增加交流损耗;超导材料的零电阻特性使得绕组限制环流的能力极低.因此,在设计超导变压器时,进行磁场分析和环流计算显得尤其重要.本文采用场-路结合的方法,即在用ANSYS求得反映变压器各支路之间电磁耦合的电感矩阵的基础上列出电路方程,计算了变压器低压绕组5种不同形式的各支路电流分布,并进而分析了磁场.同时提出了减小环流和改善磁场分布的一些措施.

| Abstract: | In a HTS transformer the leakage magnetic field decreases the critical current and increases the AC losses in the tapes, and the nearly zero resistance of HTS material greatly attenuates the ability to restrain the circulating current in the paralleled tapes.So, the numerical analysis of the leakage magnetic field and the circulating current is especially necessary for a HTS transformer design. In this paper, based on the inductance matrix the effect of the winding configuration on both the stray field and the circulating current is studied using the method of combining feld analysis and circuit calculation.Some suggestions for improving the leakage field distribution and reducing the circulating current are represented to make HTS transformers more efficient. |
