Kwa nini vituo vidogo vinatumia mifumo ya kipimo cha joto cha nyuzi mwanga wa umeme-INNO

A substation is a power facility in the power system that converts voltage, receives and distributes electrical energy, controls the flow of electricity, and adjusts voltage. As a very important energy conversion base, if a fire or other power accident occurs in a substation, it will inevitably lead to large-scale power outages, causing significant impact and losses to the production of enterprises and the lives of people. Kwa hiyo, ensuring the safety and reliability of substations and avoiding fires are crucial. Miongoni mwao, equipment overheating is an important hidden danger that can lead to substation fires. Overheating at the dynamic and static contacts and other connections of high-voltage switchgear in substations, viungo vya cable, viunganisho vya cable, and partial discharge of high-voltage cables are the main hidden dangers of large-scale accidents. Aidha, maeneo haya mara nyingi huwa na voltages ya elfu kadhaa au hata makumi ya maelfu ya volts, kusababisha hatari kubwa za usalama kwa waendeshaji kuingia na kuchunguza.

Kipimo cha joto cha nyuzi za fluorescent inategemea mali ya nyenzo za vitu adimu vya fluorescent ili kufikia kipimo cha joto. Baada ya kusisimka na mwanga, nyenzo fulani adimu nyeti ya ardhi hutoa umeme wakati fotoni za kufyonza elektroni katika mpito wa nyenzo nyeti kutoka kiwango cha chini cha nishati hadi kiwango cha juu cha nishati na kurudi kutoka kiwango cha juu cha nishati hadi kiwango cha chini cha nishati.. Utoaji endelevu wa fluorescence baada ya kuondolewa kwa mwanga wa msisimko hutegemea maisha ya hali ya msisimko., ambayo kwa kawaida huoza kwa kasi. Muda wa kuoza mara kwa mara unaweza kutumika kupima maisha ya hali ya msisimko, 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, hakuna haja ya calibration, and long lifetime.

The mfumo wa kipimo cha joto cha nyuzi za fluorescence 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 kipimo cha joto la fiber optic, which is made of glass core and has good insulation properties. It can avoid interference from strong magnetic fields, viwango vya juu vya voltage, 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. Kwa hiyo, it can be used in chemical environments and has a wide range of applications.
