Ib substation yog ib lub hwj huam chaw nyob rau hauv lub hwj huam uas converts voltage, tau txais thiab faib hluav taws xob zog, tswj cov hluav taws xob, thiab kho kom haum. Ua ib qho tseem ceeb heev conversion puag, Yog hais tias hluav taws kub los yog lwm yam hwj huam sib tsoo tshwm sim nyob rau hauv ib substation, Nws yuav inevitably ua rau loj-teev fais fab tuag, Yuav ua tau tej yam tseem ceeb thiab losses rau qhov ntau lawm enterprises thiab lub neej ntawm cov neeg. Yog li ntawd, vim, Xyuas kom muaj kev ruaj ntseg thiab reliability ntawm substations thiab tsis txhob hluav taws kub tseem ceeb heev. Ntawm lawv, Khoom overheating yog ib qho tseem ceeb nkaum uas yuav ua rau substation hluav taws kub. Overheating ntawm lub dynamic thiab static hu thiab lwm yam kev sib txuas ntawm high-voltage switchgear hauv substations, cable joints, cable sib txuas, thiab ib feem ntawm high-voltage cables yog lub ntsiab nkaum phom sij ntawm cov kev huam yuaj loj-teev kev huam yuaj. ntxiv thiab, Cov chaw no feem ntau muaj voltages ntau txhiab los yog txawm kaum tawm txhiab tus volts, posing zoo kawg thiab kev nyab xeeb rau cov tswv nkag mus thiab soj ntsuam.

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.

Qhov no 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 fiber optic ntsuas, 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. Yog li ntawd, vim, it can be used in chemical environments and has a wide range of applications.
