  • Solution for Cable Fiber Optic Temperature Measurement System

Product Introduction of Distributed Fiber Optic Cable Temperature Measurement System:

Why do cables need to monitor temperature?

During the operation of power cables, the conductor, insulation layer, and metal shielding layer will be damaged, causing the cable to heat up and increasing the working temperature of each part. Excessive temperature can affect the insulation performance of the insulation material, cause insulation aging, shorten the service life of the cable, and in serious cases, lead to fire and power outage accidents. Based on the principle of Raman scattering effect, Fuzhou Yinuo Technology has developed a technology for installing fibra óptica distribuída temperature measurement in power cables, which can achieve full monitoring of cable temperature. It has the ability to resist electromagnetic interference, continuously measure the temperature points of the fiber optic cable along each point, timely detect local temperature anomalies, analyze insulation problems of the line, and prevent cable fires, ensuring the continuous and safe operation of the cable.

Characteristics of Distributed Fiber Optic Temperature Measurement System

Temperature sensing fiber optic temperature measurement laying scheme

The laying method of temperature sensing optical fibers in cable interlayer and cable body
Temperature monitoring is required for each cable. The cable is fixed using surface mounted (external) cabos ópticos. The laying of optical cables is fixed with optical cable fixing parts (insulation ties) to tightly bond the optical cable with the outer surface of the cable.

Temperature sensing fiber optic laying diagram

Overall scheme design: Based on the actual situation of the cable, a complete fiber optic temperature monitoring system will be constructed for the monitoring cable, achieving real-time monitoring of temperature at various locations of the cable, over limit alarm, and output alarm signals.
Use one distributed fiber optic temperature sensing system to achieve online monitoring and fire alarm of the entire cable.
design scheme
The cable temperature measurement and monitoring system adopts distributed fiber optic fire detectors. Optical cables are laid on the cables, and a temperature sensing detector host is installed in the system management center. The host leads the detection optical cables to the cables. By utilizing a small portion of the diffuse scattered light reflected back along the fiber optic when the temperature changes, the signal of this backscattered light is collected and analyzed in the photoelectric device to provide information about temperature, determine the location of the rapid temperature change, and determine the point of fire occurrence. When the distributed fiber optic temperature sensing host detects a fire anomaly, the fire alarm host immediately displays an alarm.
