분산 온도 감지 광섬유 감지, 기술, solutions-INNO

Energy pipelines buried directly 3-5 meters below the ground are susceptible to external ground forces, soil settlement, pipeline and welding quality, 부식, temperature stress, and other factors that can cause leaks. The outer layer is wrapped with waterproof and insulation layers, making it difficult to find the leakage point, with long repair time and high cost. Leakage reduces the thermal insulation performance of the insulation layer in the pipeline network, while also losing energy from the pipeline system; Accelerate pipeline corrosion; The soil erosion and road collapse caused by it result in urban disasters such as traffic accidents and energy supply interruptions.

Distributed Fiber Optic Temperature Measurement 기술

Obtain spatial temperature distribution information based on fiber Raman scattering effect and Optical Time Domain Reflectometry measurement technology. By laying a temperature sensing fiber on the surface of the pipeline, the time and intensity information of Raman backscattered light generated by the propagation of light pulses inside the temperature sensing fiber are collected and analyzed to obtain corresponding position and temperature information. After obtaining the temperature and position information of each point, a temperature curve about different positions of the entire fiber can be obtained. The measurement distance can reach 30 킬로미터, and the spatial positioning can reach the order of meters, enabling uninterrupted automatic measurement, especially suitable for applications that require long-distance, large-scale, 다점 측정. 현재, this technology is widely used in temperature detection and fire alarm systems in tunnels, oil depots, dangerous goods depots, military depots, production workshops of industrial and mining enterprises, as well as cable overload temperature monitoring for power.

Temperature sensing fiber optic 발각

With the continuous development of urbanization, there are more and more cables and high-voltage switchgear in power grid construction, and the probability of faults is also increasing. According to the fault statistics, it was found that the cable and switch failure rates have been increasing year by year. 게다가, most fire accidents are caused by high temperatures. 그러므로, it is particularly important to monitor the temperature changes of cables and switchgear in a timely and accurate manner and issue alarms before a fire occurs, so that users have sufficient time to take corresponding measures. This is crucial to avoid accidents or fires. But currently, traditional temperature measurement systems are mainly used, with intermittent detection points distributed by sensors, and only the points in contact with the detection probe can be detected. The detection range is small, and the detection signal output is weak electrical signal, which is highly susceptible to electromagnetic interference; Using circuits as signal channels requires particularly high insulation for high-voltage equipment, making maintenance and repair difficult. Not suitable for comprehensive testing of temperature systems.
