Power cables are widely used in urban underground power grids, railway power grids, internal power supply of industrial and mining enterprises, and underwater power transmission lines; With the continuous expansion of the application field of power cables, the laying environment of power cables has become more complex. Power cables have evolved from simple power energy transmission to multifunctional and multi-purpose directions such as corrosion resistance, بازدارندگی شعله, water resistance, و مقاومت در برابر رطوبت.

With the rapid development of high-speed rail construction, the number of applications of power cables in railway power supply lines is also increasing day by day. The working and operating status of power cables largely determines the quality and safety of power supply. Preventing cable faults, reducing the failure rate during cable operation, and improving the reliability of cable power supply are particularly important for the safe and efficient operation of railways.

Whether used in railway power supply systems or other power supply systems, the cable core of the cable will heat up due to the action of its own resistance when passing through a larger current. The longer the time and the higher the temperature, the greater the resistance and the easier it is to heat up. This not only causes power transmission loss, but also leads to insulation material degradation, damage to the cable, and even causes safety accidents such as fires. بنابراین, the operating temperature of the cable is an extremely important parameter that characterizes the operating status of the power cable. When the cable fails, the temperature value near the fault point also increases or decreases. Due to the great concealment of power cables, which are often buried, it poses great difficulties in fault detection and accurate distance positioning. Emphasizing the fault detection and diagnosis of power cables, using advanced detection technology to accurately locate the fault points of power cables, timely maintenance, and taking safety protection measures are extremely important for the overall operation of the power system.

اندازه گیری دمای فیبر نوری technology has been applied in monitoring the operating temperature of power cables. Fiber optic temperature measurement technology is a real-time, آنلاین, and multi-point fiber optic temperature measurement technology that can monitor the spatial temperature field in real time, continuously measure the measurement points along the fiber optic cable, و در برابر تداخل الکترومغناطیسی مقاومت کند.
