摘　　要：对各种单螺旋式线圈换位过程进行深入研究，建立了数学模型，并用计算机软件实现了在任意匝数、任意并绕根数、每组有任意导体数时的换位计算。计算了螺旋式线圈在实际漏磁场分布时的环流损耗，通过实例计算得出单螺旋式线圈采用“２４２”换位比“４２４”换位损耗小的结论。采用非均匀换位区长度还可进一步降低损耗。The paper researches on transposition of various single helical winding,and sets up amathematics model.A software is provided to calculate the transposition coordinate,whenthe winding has arbitrary turns,arbitrary parallel conductors,and arbitrary conductors in agroup.The circulating current loss of the winding is computed in actual leakage magneticfield.The comparative result shows that“242”model is better than“424”;The loss can bereduced markedly through changing the turns in every area.
