由于信息技术的飞速发展,目前国内外采用新技术实现电缆故障检测及快速定位的研究也不断取得新成果,但在研究事前预警,及时干预避免故障发生方面的研究较少.对低压电力通信技术的理论和实际系统进行了研究和开发,并成功开发出实际的配电网多支路电缆带电识别系统的发送装置及接收装置.通过此系统得到的电缆属性与其它动态属性结合得到的分析结果,能为配电网的调度、故障预防提供参考.%The development on adoption of new technologies to achieve the cable fault detection and rapid positioning at present, but there is less research to avoid the failure aspects of early warning and timely intervention. This paper discussed on development of practical system and theory of low voltage power communication technology, and successful development of the practical sending device and receiving device of the multi-string cable charged recognition system. The results of the analysis combined with cable attribute and other dynamic attribute could provide reference for the power network dispatching and fault prevention.
