摘　　要：电力电缆线路运行温度和应变的在线监测是保障电力系统安全与稳定的必要措施。文章介绍了光纤布里渊传感器的测量原理,深入地分析比较了传统传感器与分布式传感器的性能,得出光纤布里渊传感器具有检测和定位精度高、受环境影响小、可长距离分布式测量等优点,并探讨了该技术在高压电缆检测方面的应用方法及应用前景。The on-line monitoring on power cable＇s temperature and strain is very important for the security and stability of power system. This paper introduces the measurement principle of fiber Brillouin sensor, compares the performances of conventional sensor and the distributed one, draws the conclusion that that fiber Bfillouin sensor has the advantages of high precision, less environmental, impact, long measurement distance etc and distributed measurement points. The application in high-voltage cable detection is also discussed in the paper.
