Distributed fiber optic temperature detector manufacturer of distributed fiber optic temperature sensing technology-INNO

Penderiaan suhu optik gentian yang diedarkan technology mainly utilizes the correlation between the intensity of Raman scattering light signals in optical nonlinear effects and temperature. By detecting and analyzing the intensity of Raman scattering light signals generated by excitation at different positions of the fiber, temperature measurement at different positions of the fiber is achieved. In distributed fiber optic temperature sensing technology, fiber optic is both a sensor and an information transmission medium. This technology has the characteristics of flexible sensor structure, continuous distribution, jarak pemantauan panjang, and high working temperature. Itu, it has broad application prospects in fields such as fire protection and early warning, oil well survey, Dll.

Power cables are widely used in urban underground power grids, railway power grids, internal power supply of industrial and mining enterprises, and underwater power transmission lines; With the continuous expansion of the application field of power cables, the laying environment of power cables has become more complex. Power cables have evolved from simple power energy transmission to multifunctional and multi-purpose directions such as corrosion resistance, kalis api, rintangan air, and moisture resistance.

With the rapid development of high-speed rail construction, the number of applications of power cables in railway power supply lines is also increasing day by day. The working and operating status of power cables largely determines the quality and safety of power supply. Preventing cable faults, reducing the failure rate during cable operation, and improving the reliability of cable power supply are particularly important for the safe and efficient operation of railways.

Whether used in railway power supply systems or other power supply systems, the cable core of the cable will heat up due to the action of its own resistance when passing through a larger current. The longer the time and the higher the temperature, the greater the resistance and the easier it is to heat up. This not only causes power transmission loss, but also leads to insulation material degradation, damage to the cable, and even causes safety accidents such as fires. Itu, the operating temperature of the cable is an extremely important parameter that characterizes the operating status of the power cable. When the cable fails, nilai suhu berhampiran titik kerosakan juga meningkat atau menurun. Oleh kerana penyembunyian besar kabel kuasa, yang sering dikebumikan, ia menimbulkan kesukaran besar dalam pengesanan kesalahan dan kedudukan jarak yang tepat. Menekankan pengesanan kerosakan dan diagnosis kabel kuasa, menggunakan teknologi pengesanan canggih untuk mengesan titik kerosakan kabel kuasa dengan tepat, penyelenggaraan tepat pada masanya, dan mengambil langkah perlindungan keselamatan adalah amat penting untuk operasi keseluruhan sistem kuasa.

Pengukuran suhu optik gentian teknologi telah digunakan dalam memantau suhu operasi kabel kuasa. Teknologi pengukuran suhu gentian optik adalah masa nyata, dalam talian, dan teknologi pengukuran suhu gentian optik berbilang titik yang boleh memantau medan suhu spatial dalam masa nyata, continuously measure the measurement points along the fiber optic cable, and resist electromagnetic interference.
