Research Progress on Cable Safety Monitoring Technology

随着电力系统规模的扩大，电缆安全监测技术的研究与应用日益重要。传统人工巡检方式存在效率低、实时性差等问题，而现代监测技术通过多物理量感知与数据分析实现了电缆状态的实时预警。本文系统综述了当前主流的电缆安全监测方法，包括高频电流监测、红外热像监测、分布式光纤传感技术等，详细阐述其理论依据、技术特点及适用场景，并对比分析其优缺点。最后展望了与5G通信、人工智能等技术融合的未来发展方向，为电缆监测技术的优化选择提供理论参考。With the expansion of the scale of power systems, the research and application of cable safety monitoring technology are becoming more and more important. The traditional manual inspection method has problems such as low efficiency and poor real-time performance, while modern monitoring technology realizes real-time early warning of cable status through multi-physical quantity perception and data analysis. This paper systematically reviews the current mainstream cable safety monitoring methods, including high-frequency current monitoring, infrared thermal image monitoring, distributed optical fiber sensing technology, etc., expounds its theoretical basis, technical characteristics and application scenarios in detail, and compares and analyzes its advantages and disadvantages. Finally, the future development direction of the integration with 5G communication, artificial intelligence and other technologies is prospected, which provides a theoretical reference for the optimal selection of cable monitoring technology.
