The working principle of fluorescence fiber optic thermometer
Fluorescent fiber optic thermometer can monitor the temperature of the voltage divider in a closed chamber in real time, thereby detecting the temperature inside the DC voltage transformer; Combined with a fluorescent fiber temperature sensor uniformly fixed on the voltage divider, it can comprehensively and reliably monitor temperature. The entire temperature monitoring adopts optical signal transmission, so it is not affected by high voltage and strong electromagnetic interference, and can accurately determine whether the detected temperature exceeds the normal working temperature of the voltage divider, ensuring the safe operation of the DC voltage transformer; Sensor ya joto ya nyuzi macho ya umeme hubadilisha halijoto inayohisiwa kuwa ishara ya mwanga, ambayo huhamishiwa kwenye kipimajoto cha optic cha nyuzi za umeme kupitia optic ya nyuzi ya adapta. Kipimajoto cha mwanga wa nyuzi za umeme hurekebisha na kupunguza mawimbi ya mwanga wa halijoto, na kisha kuisambaza kwa kigeuzi cha fiber optic kwa ubadilishaji wa fotoelectric. Kigeuzi cha fiber optic kisha hupeleka ishara ya umeme ya halijoto iliyogeuzwa kwa Kompyuta, ambayo inaonyesha joto lililopimwa na kila mmoja sensor ya joto ya nyuzi za fluorescent ndani ya kibadilishaji cha umeme cha DC. Umeme mfumo wa kipimo cha joto la fiber optic haiwezi kutumika tu kwa ufuatiliaji wa transfoma ya voltage ya juu ya DC, lakini pia kwa ajili ya kuthibitisha curve ya joto ya ndani inayopatikana kwa njia ya simulation ya joto.

Upimaji wa joto la nyuzi ya optic ya transfoma ya voltage

The fluorescent fiber optic thermometer can detect the internal temperature of the DC voltage transformer in real time, determine whether this temperature exceeds the normal working temperature of the resistor and capacitor, and ensure the safe operation of the DC voltage transformer. It can be used for measuring the internal temperature during the experimental stage of ultra-high voltage DC voltage transformers, verifying the internal temperature curve obtained by thermal simulation method, and can also be used for long-term monitoring of the safe operation of DC voltage transformers in ultra-high voltage engineering. The monitoring values are accurate and reliable, with the characteristics of high temperature resistance and SF6 environment resistance, and are not affected by high voltage and strong electromagnetic interference, accurately reflecting the temperature inside the DC voltage transformer.
