| description | The invention relates to a positioning method of a cable fault positioning device based on an electromagnetic method, and the method comprises the following steps: S1, detecting a metal pipeline through a magnetic field, and obtaining a cable path; s2, obtaining the electrification characteristic data of each cable joint, and judging which two joints a fault occurs between based on the historical data of each cable joint; and S3, according to the two joints obtained through judgment in the step S2, obtaining fault feature data to locate a fault. In the off-line state, the characteristic value of the joint is observed by additionally applying equal-proportion reduced voltage and current signals to the cable, so that the position of the fault cable joint is positioned, and a fault point can be further given in detail.
本发明涉及一种基于电磁法的电缆故障定位装置的定位方法，包括以下步骤：步骤S1:通过磁场探测金属管道，获取电缆路径；步骤S2：获取各电缆接头的电气化特征数据，并基于各电缆接头历史数据，判断故障是发生在哪两个接头之间；步骤S3:根据步骤S2判断得到的两个接头，获取故障特征数据来定位故障。本发明在离线状态下通过对电缆外加等比例缩小的电压和电流信号，来观察接头的特征值，以此来定位故障电缆接头的位置 |
