摘要
电缆故障定位是电缆抢修中至关重要的一环,其速度和精度直接影响抢修时效。为了提高电缆故障的定位速度和精度,文章开发了基于移动互联技术的移动终端,该移动终端可专网直接查看电缆路径,不再需要打印纸质图纸,应用电桥法时,可在移动终端中快速进行电缆等效长度的自动归算及实际故障位置反归算,最终将电桥及行波法中得到的故障距离直接定位到移动终端的电缆路径中,实现了电缆路径位置及故障点的快速及精确定位。
Cable fault location is an important part of cable repair, and its speed and accuracy directly affect the emergency repair time limitation. In order to improve the speed and precision of cable fault positioning, a mobile terminal based on mobile internet technology is developed. The mobile terminal can directly view the cable path and no longer need to print paper drawings, when the bridge method is applied, the automatic reduction and actual fault location of the cable equivalent length can be quickly carried out in the mobile terminal. Finally, the fault distance obtained from the bridge and the traveling wave method is directly located in the cable path of the mobile terminal, and the location of cable path and fault point can be quickly and precisely located.
