摘　　要：研究了断路器操作过程中振动的传播过程，提出了使用信号相频特性描述振动波传播过程的方法，并通过与振动信号对应的解释信号相频特性的分析，得出了一种识别在时间上相互混叠的振动事件的方法。The propagation of vibration wave creaeed during circuit breaker operation is researched . The method which uses the phase - frequency characteristic to describe the propagation of vibration wave is pro- posed . Through the analysis to the phase - frequency characteristic of the analytical signal of vibration sig- nal, a way distinguishing the different vibration events aliasing in time domain is given .
