直流电机电枢绕组绝缘的在线检测方法

摘要

本文分析了直流电机电枢绕组绝缘劣化直至一点接地时接地电压的变化规律，给出了电枢绕组绝缘的在线检测方法。%The article analyze the roles of the ground voltage varying whenthe insulation of the DC generator is armature winding weakens to one point broken down to ground. Offers the on-line way to detect the insulation of armature windings.
