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. 각 지점의 온도 및 위치정보를 획득한 후, 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, 대규모, 다점 측정. 현재, this technology is widely used in temperature detection and fire alarm systems in tunnels, 석유 저장소, dangerous goods depots, military depots, production workshops of industrial and mining enterprises, as well as cable overload temperature monitoring for power.

최근 몇 년 동안, China has gradually integrated comprehensive pipe galleries with underground projects such as subways and underground complexes into urban underground space planning, 공통적이고 포괄적인 발전을 이루다. The fire prevention requirements for comprehensive pipe galleries have gradually increased. 종합 파이프 갤러리에 적용되는 화재 경보 시스템은 주로 선형 광섬유 온도 감지입니다., 와 분산형 광섬유 sensors based on Raman scattering and optical time domain reflectometry. 전자기 간섭 저항이 강한 장점이 있습니다., 고감도, 그리고 저렴한 비용. 그렇지만, 습한 환경의 특성에 적응하기 위해, 복잡한 파이프라인, 종합 파이프 갤러리의 높은 화재 예방 요구 사항, 선형 광섬유 온도 감지 시스템의 성능을 더욱 향상시켜야 합니다..

Temperature sensing fiber optic 발각

지속적인 도시화 발전으로, 전력망 건설에는 점점 더 많은 케이블과 고전압 개폐 장치가 있습니다., 오류가 발생할 확률도 증가합니다.. According to the fault statistics, it was found that the cable and switch failure rates have been increasing year by year. 더욱이, 화재사고 대부분은 고온으로 인해 발생. 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, 감지 프로브와 접촉된 지점만 감지할 수 있습니다.. 감지 범위가 작습니다., and the detection signal output is weak electrical signal, 전자기 간섭에 매우 취약합니다.; Using circuits as signal channels requires particularly high insulation for high-voltage equipment, 유지보수 및 수리가 어려워짐. 온도 시스템의 포괄적인 테스트에는 적합하지 않습니다..
