摘　　要：利用分离变量法，在计及无槽电枢绕组空间几何尺寸和简化补偿筒中涡流分布的情况下，通过对气隙磁场分析，导出了被动补偿脉冲发电机无槽电枢绕组瞬态电感的解析表达式，应用此公式，对２５ＭＷ样机进行了实例计算，分析了影响电感的主要因素。In this paper,the magnetic field in air gap of passively compensated pulsed alternator is analyzed by the separate variable method with considering the dimension of armature air gap winding and simplified the eddy current distribution in the continuous conductive shield.The analytical solution for transient inductance of armature air gap winding is deduced.A 25 MW prototype is taken as an example for calculation.Finally,some factors which affect the inductance are discussed.
