Distributed Optical Fiber Sensor and Its Application Study in Monitoring System on Power Points

This article has introduced the basic principle and technical indexes of distributed optical fiber sensor, which provides theoretical basis for real-time temperature acquisition and monitoring system on power points in the facilities of transformer substation, switching station and other corresponding electricity facilities. The system proposed above can obtain the variation curves of temperature on power points and prompt the key variation of temperature and anomalous situation in the operation process of the system, which improved the management level of electricity system and reduced the security incidents caused by anomalous temperature.
