Description

technical field [0001] The invention belongs to the technical field of cable fault detection, and in particular relates to a cable fault detection and early warning system based on optical fiber communication. Background technique [0002] Compared with overhead wires, cables have the advantages of being safe, reliable, less affected by weather, occupying a small area, and concealed, so cables are more and more applied to high and low voltage transmission lines. However, the increase in the use of cables is accompanied by the continuous occurrence of cable faults, because power cables are generally buried underground. Once a fault occurs, it is very difficult to find it, and it often takes hours or even days. This not only wastes a lot of manpower and material resources, brings a lot of inconvenience to people's daily life, but also causes incalculable economic losses. For a long time, in order to ensure the safe operation of the power system, the power industry has been co...
