摘　　要：为分析大型同步电机空心导体的集肤效应，采用了将导体分层处理的方法。根据电路基本定律，列出了计算各层定流的矩阵方程并推导了有关的计算公式。对不同空心导体的最大电流密度与损耗增加系数进行了数值计算。In order to analyse skin effect of stator hollow conductor in large synchronous machines, the paper proposes a method which separates conductor into many laryers.Based on elementary circuit theorems, the matrix equations for calculating layer currents are set up and some formulas are deduced. Gives numerical calculated results of maximum current dsnsity and loss increase coefficients for different hollow conductors.
