Fiberoptesch Temperatursensor, Intelligent Iwwerwachung System, Verdeelt Léngen OPTIC Hiersteller a China

Eng Ënnerstatioun ass eng Stroumanlag am Kraaftsystem déi Spannung konvertéiert, kritt an verdeelt elektresch Energie, kontrolléiert de Stroum vum Stroum, an ajustéiert Volt. Als eng ganz wichteg Energiekonversiounsbasis, wann e Feier oder aner Muecht Accident an enger substation geschitt, et wäert zwangsleefeg zu grouss-Skala Muecht outages Féierung, verursaacht bedeitend Impakt a Verloschter fir d'Produktioun vun den Entreprisen an d'Liewe vu Leit. Dofir, d'Sécherheet an d'Zouverlässegkeet vun den Ënnerstatiounen ze garantéieren an d'Feier ze vermeiden sinn entscheedend. Ënnert hinnen, Ausrüstung Iwwerhëtzung ass eng wichteg verstoppt Gefor déi zu Ënnerstatiounsbränn féieren kann. Iwwerhëtzung bei den dynamesche a statesche Kontakter an aner Verbindunge vun Héichspannungsschalter an Ënnerstatiounen, Kabel Gelenker, Kabel Verbindungen, an deelweis Offlossquantitéit vun héich-Volt Kabelen sinn déi Haapt verstoppt Gefore vun grouss-Skala Accidenter. Ausserdeem, dës Plazen hunn oft voltages vun e puer dausend oder souguer zéngdausende vun volts, stellt grouss Sécherheetsrisiken fir d'Bedreiwer eran an z'ënnersichen.

Fluorescent fiber temperature measurement is based on the material properties of rare earth fluorescent substances to achieve temperature measurement. After being excited by light, a certain rare earth sensitive material emits fluorescence when the electron absorption photons in the sensitive material transition from low energy level to high energy level and return from high energy level to low energy level. The sustained fluorescence emission after the elimination of excitation light depends on the lifetime of the excited state, which usually decays exponentially. The decay time constant can be used to measure the lifetime of the excited state, which is called the fluorescence lifetime. The fluorescence lifetime depends on the temperature, and the biggest advantage of using this method for temperature measurement is good stability, no need for calibration, and long lifetime.

Déi fluorescence fiber optic temperature measurement system is installed at the bottom outlet of the object being measured. The system can monitor the temperature at the bottom of the object in real time and achieve rapid and accurate temperature measurement of the liquid being measured. The temperature detection speed of this temperature measurement system is fast, and it can reach the mS level at the fastest. The accuracy of temperature measurement is high, and it can achieve within ± 1 ℃. It can effectively monitor the highest temperature of the chemical liquid of the measured object, making the reaction more accurate.

The fluorescence fiber optic temperature measurement system uses Glasfasertemperaturmessung, which is made of glass core and has good insulation properties. It can avoid interference from strong magnetic fields, high voltages, and large currents generated during transformer operation, enabling measurement esults are relatively accurate. The fluorescent fiber thermometer is installed in an explosion-proof box, which can prevent chemical explosions caused by instrument ignition and other factors. Dofir, it can be used in chemical environments and has a wide range of applications.
