With the development of society and the increasing demand for electricity, high-voltage cables, as an important part of the power system, are of great significance to the stability and reliability of the power system. Due to various reasons such as long-term operation of cables, aging, and environmental factors, cable failures occur from time to time, which will have a very serious impact on the normal operation of the power system. High-voltage cables may fail during operation, how to quickly and accurately locate the fault point and eliminate the fault is a difficult and key problem faced by maintenance personnel.
Cable fault location and early warning is an important technical means to ensure the stable operation of the power system, which can timely and accurately find and deal with potential fault hazards and reduce the impact of faults on the power system. The high-voltage cable fault warning and precise positioning system based on the principle of traveling wave positioning designed and developed by Shaanxi Public provides an effective solution to solve this problem.
The high-voltage cable fault warning and precise positioning system adopts satellite optical fiber to accurately time, which ensures the accuracy and reliability of time synchronization and provides an accurate time benchmark for fault location. After the fault of the high-voltage cable, the system can quickly and accurately calculate the location of the fault point by detecting the traveling wave signal generated by the fault and combining it with the time information provided by the precision timing system. At the same time, the system also has a fault warning function, through the real-time monitoring and analysis of the cable operation status, the potential fault hidden dangers can be found in time, which provides strong support for preventive maintenance.
The application of high-voltage cable fault warning and precise positioning system not only improves the accuracy and efficiency of high-voltage cable fault location, reduces unnecessary power outage time, but also provides more convenient and efficient troubleshooting methods for maintenance personnel. At the same time, the high-voltage cable fault warning and precise positioning system can also be applied to the fault warning and positioning of other power equipment and lines, providing a strong guarantee for the stable operation of the power system.
