摘要

由于多导体电缆中存在信号结，采用扩频时域反射法(SSTDR)在线检测容易出现误判，且反射信号幅度过小而无法检测。本文采用适当安装的捕集器实现探测信号的定向传输，消除了信号收敛的影响。并提出了一种多通道分时周期检测方法来简化检测器。仿真和实验表明，该方法可以成功地检测多芯电缆的故障。

Research on online detection and location of multi-conductor cables' faults

Due to the existence of signal junctions in multi-conductor cables, on-line detection using spread spectrum time domain reflectometry(SSTDR) method is prone to a misjudgment, and the amplitude of reflected signal is too small to be detected. In this paper, trappers with proper installation are used to realize directional transmission of detection signal, which can eliminate the effect of signal converging. And a multi-channel time-sharing cycle detection method is proposed to simplify the detector. Simulations and experiments indicate that multi-conductor cables' fault can be detected successfully.
