Why do substations use fluorescent fiber optic temperature measurement systems

Pūoko pāmahana whakaata Fiber, Pūnaha aroturuki Intelligent, kaiwhakanao whakaata tākainga tūari i Haina

Ko te taupuniroto he pūtake hiko i roto i te pūnaha hiko e tahuri ana i te ngaohiko, whiwhi me te tohatoha i te pūngao hiko, ka whakahaere i te rere hiko, ka huri i te ngaohiko. Hei pūtake tahuringa pūngao tino hira, mēnā ka puta he ahi, tētahi atu aituā hiko rānei i roto i tētahi taupuniroto, mā tēnei e ahu atu ki ngā putanga hiko tauine nui, nā te nui o te pānga me te hinganga ki te whakanaotanga o nga taiete me nga oranga o te iwi. Nō reira, He tino nui te whakarite i te haumarutanga me te whaikikotanga o ngā taupuniroto me te karo i te ahi. I waenganui i a rātau, He mōrearea huna hira te whakaputa taputapu e āhei ana ki te ahi taupuni-roto. Kei te whakaiti i ngā hoapā hihiri, pateko hoki me ētahi atu tūhononga o te whakawhiti ngaohiko tiketike i roto i ngā taupuniroto, hononga taura, hononga taura, ā, ko te whiwhinga wāhanga o ngā taura ngaohiko tiketike ko ngā mōrearea huna matua o ngā aituā tauine nui. Waihoki, I ētahi wā he ngaohiko o ēnei wāhi, kotahi tekau mano rānei o nga rewa, Kei te whakawātea i ngā mōrearea haumaru nui kia tomo, kia tūhura hoki ngā tohutūmahi.

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.

The 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 °C. 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 inenga pāmahana whakaata tākaka, 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. Nō reira, it can be used in chemical environments and has a wide range of applications.
