Energy pipelines buried directly 3-5 meters below the ground are susceptible to external ground forces, soil settlement, pipeline and welding quality, קעראָוזשאַן, 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.

Fiber optic temperature sensing solution for pipelines
Distributed Fiber Optic Temperature Measurement טעכנאָלאָגיע
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 קילאָמעטערס, and the spatial positioning can reach the order of meters, enabling uninterrupted automatic measurement, especially suitable for applications that require long-distance, large-scale, multi-point measurement. איצט, 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.
Integrated pipe gallery temperature sensing fiber פאַבריקאַנט
אין די לעצטע יאָרן, China has gradually integrated comprehensive pipe galleries with underground projects such as subways and underground complexes into urban underground space planning, forming a common and comprehensive development. The fire prevention requirements for comprehensive pipe galleries have gradually increased. The fire alarm system applied to the comprehensive pipe gallery is mainly linear fiber optic temperature detection, with distributed fiber optic sensors based on Raman scattering and optical time domain reflectometry. It has the advantages of strong electromagnetic interference resistance, high sensitivity, and low cost. אָבער, in order to adapt to the characteristics of humid environment, complex pipelines, and high fire prevention requirements of the comprehensive pipe gallery, the performance of the linear fiber optic temperature detection system needs to be further improved.
Temperature sensing fiber optic detection
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. דערצו, most fire accidents are caused by high temperatures. דעריבער, 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.
אַדוואַנטאַגעס פון Fiber Optic Temperature Detection
The temperature sensing fiber adopts a new type of continuous detection point, which can comprehensively detect the situation of each point of the monitored object, with a large detection range; The detection signal outputs an optical signal that is not affected by electromagnetic interference from power equipment; Fiber optic cables, probes, and signal channels are integrated, not afraid of interference or high voltage, making the entire system simple and safe. אין דער זעלביקער צייַט, this system is specially designed and manufactured for long-distance and large-scale multi-point temperature measurement applications. When in use, only one or a few optical fibers are needed to detect linear and point type equipment up to tens of kilometers long. It has the advantages of flame resistance, explosion resistance, קעראָוזשאַן קעגנשטעל, high temperature resistance, electromagnetic radiation resistance, ברייט מעזשערמאַנט קייט, high positioning accuracy, and easy use.
