Application of fiber optic cable sensor in power new energy
Date: 2018-02-01
The application of optical fiber sensor in new energy temperature measurement is mainly based on the characteristics of high bandwidth and strong anti-jamming ability, and no matter how bad the condition is, the problem can be detected and repaired in time. With the help of optical fiber sensor to monitor the surface temperature of power cable and the temperature of cable dense area, the temperature of cable interlayer and cable tunnel in power plant and substation area should be measured and monitored in the process of running monitoring system. To effectively monitor the cable, the temperature measurement of optical fiber and cable surface to fit, read the effective cable surface temperature coefficient, and the use of curved form to express the cable load current, from the actual numerical value of the conductor temperature coefficient of the effective estimation, pay particular attention to the surface temperature changes and the difference between the conductor temperature changes, Strengthen the maintenance and control of system Operation security.
