Abstract

The distributed optical fiber temperature measurement system realizes the early warning of fire hazards through the real-time temperature monitoring of cable lines, and significantly improves the security of power system. With the increasing complexity of power equipment and the increase of power demand, the traditional means of fire early warning can not meet the needs of modern cable fire early warning. The temperature measurement system based on optical fiber sensing technology can accurately detect temperature changes in a large range, timely detect temperature anomalies, and early warn potential fire risks. This paper discusses the application of distributed optical fiber temperature measurement system in cable fire early warning, analyzes its technical advantages, engineering implementation difficulties and practical application effect, and provides an innovative solution for fire prevention and control of power system.
