摘　　要：对利用动态整定实现故障电信号快速检测电路的动态特性进行了分析和模拟实验。用数字贮存示波器（ＤＳＯ）记录了各参量的动态变化过程，结果表明，快速检测电路在动态下能对故障电信号进行快速检测。The fast detection circuit for fault electric signal based on instantaneous state limitation is analyzed and simulated. Various parpmeters in the course of dynamic variation are recorded by digital oscillograph. The results show that fast detection circuit may instantaneously detect the fault electric signal under dynamic state and the sampling time is rather short.
