摘要
动力电缆温度监测是可以及时发现电缆线路过热点位置和检测运行线路的绝缘状态,从而保障电缆安全稳定运行的技术措施。针对电缆过热事故的主要原因和特点,提出采用分布式光纤测温技术对电缆沿线温度进行监测预警,给出了分布式光纤测温系统的原理、组成和光缆布设方案,此系统对保证电力系统的安全运行有重要意义。
Technology of power cable temperature testing is an important technology to submit the location of local overheating,detect the installation status,and ensure the safe and stable operation of power cable.Aimed at the main cause and characteristics of power cable conflagration accident,this paper present a solution that adopts distributed optic fiber temperature monitoring technology to warn early along the line,and introduces the principle,composition,and optical fiber assembly method of the temperature monitoring system based on distributed optic fibre sensing technology.The system have very important meaning to ensuring that the electric power system safety works.
