摘　　要：对于电抗器具有电流大、匝数少的特点,其绕组一般采用多根导线并联的分段层式绕制方法,而分段层式的换位方法一般采用每段每层分别完全换位,这种换位方法虽然可以达到完全换位的目的,但是大大降低了绕组绕制的效率。本文中作者针对该问题采用漏磁对导线产生的涡流进行了精确计算,优化了换位方法,以实际的电抗器作为计算实例,进行了详细的说明。The reactor has the characteristics of large current and few turns.Its coil generally adopts the subsection layer winding method with multiple wires in parallel,while the subsection layer transposition method generally adopts the complete transposition of each section and each layer.Although this transposition method can achieve the purpose of complete transposition,it greatly reduces the efficiency of coil winding;Aiming at this problem,this paper uses magnetic flux leakage to accurately calculate the eddy current generated by the conductor,optimizes the transposition method,and takes the actual reactor as an example.
