Problems solved by technology

This new type of submarine cable combines cables and optical cables to transmit power and data at the same time, which not only saves costs, but also reduces the number of cable laying constructions. It is favored in applications such as cross-sea power transmission and communication between shallow sea islands; With the increase in development and the continuous expansion of the scale of marine resource development, more and more submarine cables need to be laid. Due to the influence of factors such as construction facilities, construction technology, high-load operation of cables, complex geological structures in sea areas, and complex operating environments at sea, Due to local accidental force, failures such as disconnection and short circuit of submarine cables in operation often occur, resulting in huge economic losses
The social impact and economic loss caused by the submarine cable failure are very large, and it must be repaired as soon as possible

Description

technical field [0001] The invention relates to the field of submarine cables, in particular to an intelligent protection system based on submarine cables. Background technique [0002] The development of offshore energy such as offshore wind power has promoted the formation of offshore transmission networks, and high-voltage submarine power cables have increasingly broad application space, mainly including offshore wind power transmission, power supply for offshore oil and gas platforms, island networking, and coastal country networking. As the most important equipment in the offshore transmission network, the safe operation of submarine cables is very important to the power system. [0003] Submarine cables are wires wrapped in insulating material and laid on the seabed for power and information transmission. According to the use, it can be divided into power cables, photoelectric composite cables, communication optical cables, etc. In recent years, photoelectric composi...
