摘　　要：本文提出了一种基于直接冲击电压对电器绕组匝间绝缘的试验方法。用电压波形比较法,把冲击电压经高速切换,交替施加于被测绕阻两端和参考物绕组两端,通过观察电压衰减振荡波形的变化,便可检测被测绕组的匝间是否有异常。A test method for insulation between coils of electrical equipment based on directly impulse voltage are presented. Compared to voltage oscillation waves, the abnormity between tested coils can be detected by observing the change of voltage decaying oscillation waves.
