一种断路器燃弧起始时间检测系统及检测方法
摘要：
本发明公开了一种断路器燃弧起始时间检测系统，包括两个电磁波信号采集装置，第一电磁波信号采集装置与断路器A相的距离和第二电磁波信号采集装置与断路器C相的距离相同，第一电磁波信号采集装置与断路器B相的距离和第二电磁波信号采集装置与断路器B相的距离相同；两个电磁波信号采集装置的信号输出端分别连接示波器。本发明通过合理布局天线并比较电磁波到达天线的时间差即可确定燃弧起始时间对应的相别，简单易行，测量精度高，并且与系统无电气连接，安全可靠，同时还能够区分出断路器A相、B相和C相中哪一项首先出现电弧。
摘要（英）：

The invention discloses a breaker arcing starting time detection system. The breaker arcing starting time detection system comprises two electromagnetic wave signal acquisition devices. The distance between the first electromagnetic wave signal acquisition device and the Phase A of a breaker is the same as the distance between the second electromagnetic wave signal acquisition device and the Phase C of the breaker, and the distance between the first electromagnetic wave signal acquisition device and the Phase B of the breaker is the same as the distance between the second electromagnetic wave signal acquisition device and the Phase B of the breaker. The signal output ends of the two electromagnetic wave signal acquisition devices are respectively connected with an oscilloscope. According to the system, the phase corresponding to arcing starting time can be determined by reasonably arranging antennas and comparing the time difference of electromagnetic waves for reaching the antennas, the system is simple, feasible, high in measurement accuracy, free of electrical connection, safe and reliable, and meanwhile it can be distinguished that which one of the Phase A, the Phase B and the Phase C of the breaker firstly generates electric arcs.
