摘要
为了精确探测地埋电缆接地故障点具体位置,使用双频混合法,利用电磁法原理,设计了一种电缆故障定位系统。该系统由路径检测和A字架定位两大模块组成,通过两大模块采集磁场信号,然后对模拟及数字信号进行处理,以提取有用信号。从解决实际需求出发,研究了电缆故障定位系统工作原理,设计了系统的构架和模块框图,并实现路径检测与故障定位的功能。
In order to accurately detect the location of the ground fault point of buried cable,a cable fault location system is designed by using the dual-frequency hybrid method and the principle of electromagnetic method.The system consists of two modules:path detection and A-frame positioning.Magnetic field signals are acquired through two modules,and analog and digital signals are then processed to extract signals of interest.Starting from solving the actual requirements,the working principle of the cable fault location system is studied,the architecture and block diagram of the system are designed,and the functions of path detection and fault location are realized.
