High voltage submarine cables have the advantages of corrosion resistance, good impact resistance and long electrical life, and are an important part of the offshore power transmission system. To ensure the normal operation of the submarine power transmission system, a high voltage submarine cable pinpointing system based on weak magnetic detection technology has been designed and developed. A submarine weak magnetic detector is installed as the actuating element of the weak magnetic detection technology, and the high-voltage submarine cable is retrofitted with a precise locator. An equivalent model of the high-voltage submarine cable and its magnetic field is constructed based on the composition and structure of the cable, the working principle of electrical engineering and the magnetic field distribution characteristics. The real-time state data of the high-voltage submarine cable is collected and the magnetic signal around the high-voltage submarine cable is obtained by using the weak magnetic detection technology, and the high-voltage submarine cable is precisely located by matching the signal characteristics and calculating the coordinates. Compared with the conventional positioning system, the average error of the optimised system in locating the static cable is reduced by about 10.82m and the average error in locating the dynamic cable is reduced by 11.37m, indicating that the designed system has obvious advantages in terms of positioning accuracy.
