摘　　要：从分析绕组区域磁场着手,通过计算载流导体在磁场中受力而获得绕组受力,考虑到超导变压器绕组因电阻小抑制环流的能力大大降低,绕组支路电抗微小的不平衡可能引起很大的环流,建立了计入环流影响的"场-路"耦合的磁场分析模型.同时,将ANSYS软件应用于"场-路"耦合分析,做了探索.得到的磁场和电磁力的计算结果与理论分析相符,给出的方法可用于进行基于磁场计算的绕组并联支路或并绕导线之间的环流分析.Electromagnetic force under short circuit is obtained directly based on the analysis of the magnetic field. Because of nearly zero resistance of high temperature superconducting （HTS） tapes, a slight unbalance of the branch inductances of the windings might result in heavy circulating current. A model for the field analysis is established by coupling magnetic field with electric circuit for including the effect of it, and the results are in good agreement with the theoretic analysis. The exploration is made in the paper about the application of ANSYS software to the method of coupling magnetic field with electric circuit and it can be also used to analyze the circulating current of windings paralleled with multi branches or conductors.
