Large industrial enterprises such as power plants and substations are equipped with a large number of power cables and control cables, and are connected to high-voltage switchgear. These cables are distributed in cable tunnels, cable trays, and cable interlayers, respectively connected to various electrical equipment, and connected to the control room, and the cables are generally laid in a concentrated manner, which is extremely harmful after a cable fire accident. For running cables, it is important to find hot spots in time (especially cable joints with hidden dangers) and other environmental anomalies for safe operation.
The distributed optical fiber temperature sensing system consists of optical fiber temperature measuring host, temperature sensing fiber, system management software and related accessories. It uses Raman scattering and OTDR technology to realize temperature monitoring and positioning. Distributed optical fiber temperature sensing products use OTDR technology for temperature monitoring and positioning. It is a real-time, online, continuous temperature measurement system. The system can accurately detect the temperature of the temperature measurement point, and has the advantages of real-time online, high temperature measurement accuracy, intrinsic safety and immunity to electromagnetic interference. It can be widely used in electric power, petrochemical, transportation, metallurgical and other industrial places, in the production process. Real-time online monitoring of temperature conditions eliminates faults and accidents in the bud, and truly prevents them from happening.
