In recent years, there have been a series of problems such as the difficulty of operation and inspection appeared in the operation and maintenance of overhead transmission lines. The rapid identification and disposal of transmission line faults has become an inevitable requirement for improving the quality of inspection. In this paper, on-line monitoring technology of transmission lines based on multi-dimensional state-aware technology is researched, which includes distributed fault diagnosis, transmission line video monitoring, and lightning monitoring system. The visualization and intelligentization of the transmission line management could be realized with this this technology. The video monitoring terminal and fault rapid diagnosis information could be linked, and the fault point of the transmission line could be quickly and accurately located, which to accurately identify the cause of the failure of the transmission line. In 2019 the 110kV lightning strike failure of a certain line was effectively monitored with this system, guiding the operation and maintenance staff to quickly locate the fault point and handle the defects. The effectiveness and accuracy of the technology is verified in this example . |
