High-voltage power cables are the lifeblood of urban modernization development and construction. Cable rows are reinforced concrete structures outside cables, which are crucial to the safe and stable operation of high-voltage cable lines. High-voltage power cable pipes are buried underground and have a special structural form. At the same time, they are faced with the influence of many external factors such as illegal construction and foundation settlement. Effective operation and maintenance management of them has always been a major problem in the industry. Aiming at the problems of lack of basis for evaluating the structural status of high-voltage power cable rows, difficulty in effectively detecting internal deformations and cracks in the rows, and lack of real-time monitoring methods for external damage, the project focuses on the monitoring of deformation of power cable rows, crack detection, prevention of external damage, etc. Research has been carried out, and a series of results have been achieved and engineering applications have been realized. The main innovations include: (1) It was the first to establish a set of safety sensitivity parameters and protection indicators suitable for the deformation of various power cable tube structures, and developed a power cable tube deformation monitoring system based on distributed optical fiber sensing technology. High-precision online monitoring of power cable tube deformation and settlement provides a basis for the status evaluation of power cable tube structure. (2) Developed a mobile high-frequency radar flaw detection system for power cable rows based on bow-tie antennas, which realized the detection of millimeter-level cracks and steel bar distribution in the power cable row structure, and improved the level of non-destructive testing of the power cable row structure. (3) Integrate distributed optical fiber vibration sensing, radar monitoring and video surveillance technologies, and develop an intelligent anti-external loss early warning and monitoring system for power cable row channels, which improves the accuracy of early warning of external force damage to power cable row pipes and realizes multi-dimensional intelligent monitoring and early warning of external force damage to power cable row pipes. Relying on research results, he obtained 4 invention patents, 1 software copyright, and published 12 scientific and technological papers. It has reached the international advanced level after identification. The project results have been successfully applied in power protection work such as the China International Import Expo and important power cable layout and management projects, with a total of more than 200 systems installed. The operation results show that the system is stable and reliable, which significantly improves the intelligent monitoring level of power cable piping. Among them, in the demonstration project in Xinjiangwan area, hidden dangers of structural weakness inside the drainage pipe were discovered; during the ground-penetrating radar inspection of the power cable drainage pipe on Sanxin Road, Ledu West Road, Songjiang District, cracks in many places were found. From 2016 to 2018, the project saved a total of 46.03 million yuan, with significant economic and social benefits. The project results have successfully upgraded the monitoring and management method of high-voltage power cable layout from traditional manual inspection to intelligent monitoring. The cost is less than one-thousandth of the cost of the power cable layout project, which is well adapted to the current situation of high-voltage power cable layout in large and medium-sized cities. The scale of power cable layout is growing rapidly year by year. At the same time, it also greatly reduces cable line failures caused by the destruction of high-voltage power cable rows, effectively improves the reliability and safety of urban power grids, and plays a leading role in the technological progress of the entire industry in intelligent monitoring of power cable rows.
