摘　　要：阐述一种基于温度的电力电缆接地线防盗监控装置方法,通过单模长距离光纤测温及长距离光纤振动的分析,基于单模通讯光缆的电缆沟环境温度及电缆防盗综合实时在线监测。从根本上解决及时发现、定位并预警对电力电缆的外力破坏行为,提前感知电缆沟环境温度异常及外力破坏点,能够为电力电缆的安全运行及管理部门和人员及时发现环境温度异常变化和偷盗事件,为电力电缆的安全运行提供有力的技术保障。在实际应用时,该方法对温度的感应可以控制在±2℃,通过温度的变化,测出对应的距离控制在±5m,从而实现电缆的监控,为电缆的监测提供新的方法。This work proposes a temperature-based power cable grounding wire anti-theft monitoring device method. Through single-mode long-distance optical fiber temperature measurement and long-distance optical fiber vibration analysis, the integrated real-time online monitoring of cable trench ambient temperature and cable anti-theft based on single-mode communication optical fiber is studied. Fundamentally solve the problem of timely detection, location and early warning of external force damage to power cables, and early detection of abnormal temperature in the cable trench and external damage points, which can help the safe operation of power cables and management departments and personnel to detect abnormal changes in environmental temperature and theft in time The incident provides a strong technical guarantee for the safe operation of power cables. In actual application, the method can control the temperature sensing within ±2℃, and through the temperature change, the corresponding distance measured is controlled within ±5 m, so as to facilitate the monitoring of cables, and also provides a new method for future cable monitoring methods.
