| 摘 要： | 在用有限元法求解磁场并计算电感矩阵的基础上,采用场—路结合的方法,针对二次绕组几种不同情形进行了环流计算。结果表明为减小环流,二次绕组轴向并绕的多根导线必须在层间换位,而在二次绕组各层两端短接后用铜线过渡到相邻层时环流不可忽视。 |

| Abstract: | In this paper, based on the inductance matrix obtained from the result of the field calculated by finite element method (FEM), the circulating current for several different configurations of the secondary windings is calculated using the analysis method of combining field and circuit. It can be concluded that for the reduction of the circulating current the 6 axially paralleled tapes must be transposed among the layers of the secondary windings and the 12 paralleled tapes cannot be joined together at each end of the layers and copper wires cannot be used to connect them for transposition. |
| Keywords: | HTS transformer FEM a field-circuit method calculation of circulating current |
