三相断路器电磁波信号相别检测系统及方法
摘要：
本申请实施例公开一种三相断路器电磁波信号相别检测系统及方法，通过在三相断路器周围设置第一天线和第二天线，利用第一天线和第二天线，接收三相断路器分闸时产生的电磁波信号，之后分别将电磁波信号转换成第一电压信号和第二电压信号；利用信号采集处理装置，获取第一电压信号和第二电压信号，然后计算第一电压信号和第二电压信号的接收时间差；最后根据接收时间差，输出电磁波信号所对应的相别，从而检测出每个电磁波信号所对应的具体相位，便于对严重烧蚀的触头进行及时处理，避免触头由于烧蚀程度过重而发生故障，保证电力系统的正常运行。
摘要（英）：

An embodiment of the invention discloses a system and a method for detecting phases of electromagnetic wave signals of a three-phase circuit breaker. A first antenna and a second antenna are arranged around the three-phase circuit breaker and are used for receiving the electromagnetic wave signals generated when the three-phase circuit breaker is switched off and converting the electromagnetic wave signals into a first voltage signal and a second voltage signal, a signal acquisition and processing device is used for acquiring the first voltage signal and the second voltage signal and computing a receiving time difference between the first voltage signal and the second voltage signal, and the phases corresponding to the electromagnetic wave signals are outputted according to the receiving time difference, so that the specific phase corresponding to every electromagnetic wave signal is detected, timely handling of severely ablated contacts is facilitated, faults caused by severe ablation of the contacts are avoided, and normal running of a power system is guaranteed.
