Cable trench cable temperature measurement system, tufaki e filo optic e ʻea
Tufaki e mafana ʻo e ʻea (DTS) system, which uses optical fibers as temperature sensing elements, is electrically neutral and inherently safe. Each point on the optical fiber is a temperature measuring element, which can achieve simultaneous temperature measurement of multiple points over a large range. The temperature sensing fibers can be arranged in a certain spatial position according to actual needs, thus realizing spatial measurement of three-dimensional temperature fields (such as chemical reaction vessels). This emerging temperature measurement technology is based on the Raman scattering characteristics of optical fibers and combined with the principle of fiber laser radar to achieve distributed temperature detection. By using the temperature characteristics of the target system, it can achieve functions such as thermal pipeline leakage, insulation layer failure, crude oil pipeline leakage, cable joint partial discharge, cable tray wire leakage, and dam leakage points. Monitoring. The system is inherently safe, radiation free, and has strong anti-interference capabilities. It is easy to deploy, has a wide detection range, and is easy to maintain. Its warning function is incomparable to traditional fire detection systems.
The distributed fiber optic temperature measurement system is designed and manufactured specifically for large-scale multi-point temperature measurement applications. With this system, one or more (using fiber optic switching modules) temperature measurement fibers can be used to measure the distribution of temperature fields in their respective locations. It has the advantages of flame resistance, explosion resistance, corrosion fakafepaki, fakafepaki voltage maʻolunga, electromagnetic radiation resistance, fua lahi, high positioning accuracy, and easy use.
