Description

technical field

[0001] The invention belongs to the technical field of power cable transmission, in particular to a power cable fault detection system. Background technique

[0002] After the power cable is installed and used, sometimes there will be a cable fault, resulting in the failure of normal power supply. Since the power cables are installed together in groups, when a power cable fails, it is necessary to find out the failed power cable from the group of power cables for processing. At present, the power cable fault detector is usually used to detect the fault point of the power cable. However, when using the fault detector for detection, the maintenance personnel need to carry the fault detector along the line to detect, which is not only time-consuming and laborious, but also often leads to detection errors. In some cases, even personal danger accidents may occur. Contents of the invention
