Single or multiple cable lines are laid in various ways such as direct burial, pipelines, trenches, tunnels, corridors, etc. In the daily maintenance of the cable line, it is often encountered that the geographical information of the cable radiation is incomplete or the cable label is not clear. At this time, in order to ensure the safety of the operator, it is necessary to detect the live state of the cable. With the continuous development of the electric power industry, the number of high-voltage cables is rising sharply. Faced with the ever-increasing line scale, the corresponding operation and maintenance personnel for transmission network cables are very limited. In terms of preventing external force damage of transmission network cables and pre-testing and repairing of cable outer sheaths, a lot of manpower and material resources are occupied, and the operation and maintenance situation is very severe. In addition, as the power quality requirements of the power grid become higher and higher, the reliability assessment standards of power supply are increased, the cable maintenance indicators are getting fewer and fewer, and the troubleshooting time is getting shorter and shorter. , The prevention of circuit failure puts forward higher requirements.
