摘　　要：介绍一种基于辐射电磁波信号实现断路器三相不同期时间带电检测方法,通过分析辐射电磁波闭合信号与开断信号的幅值特征和频谱特征,再结合现场应用实际测试,提出利用断路器开断和闭合过程中测得的辐射电磁波信号进行同期性判定的建议。A method based on radiated electromagnetic wave signal to realize three-phase live detection of circuit breaker in different periods was introduced.By analyzing and comparing the amplitude and frequency spectrum characteristics of the closed signal and the on-off signal of the radiated electromagnetic wave,and combining with the practical test in the field,the suggestion of using the radiated electromagnetic wave signal measured during the opening and closing process of the circuit breaker to determine the synchronization was proposed.

关 键 词：辐射电磁波信号 不同期时间 幅值特征 频谱特征
