Voltage regulation in transformers is qhov txawv ntawm qhov tsis muaj load voltage thiab tag nrho load voltage. Qhov no feem ntau yog qhia nyob rau hauv feem pua. Piv txwv li: Lub transformer xa 100 volts ntawm tsis muaj load thiab qhov voltage poob mus rau 95 volts ntawm tag nrho cov load, cov kev cai yuav yog 5%.
Vim li cas transformer ua haujlwm?
Lub hauv paus ntawm lub tshuab hloov pauv ua haujlwm rau coj txoj hauv kev ntawm cov hlau nplaum ntawm cov kauj ruam tseem ceeb thiab theem nrab kom tsis txhob siv lub zog khib nyiab. Thaum lub magnetic teb mus txog qhov thib ob kauj, nws yuam cov electrons nyob rau hauv nws txav, tsim ib tug hluav taws xob tam sim no ntawm electromotive force (EMF).
Dab tsi yog qhov tseem ceeb ntawm qhov hloov pauv?
Primary voltage yog qhov voltage siv rau cov terminals ntawm thawj winding ntawm transformer. Lub zog siv rau lub hauv paus yuav tsum yog nyob rau hauv daim ntawv ntawm ib tug hloov voltage uas tsim ib tug tas li hloov tam sim no nyob rau hauv thawj, vim tsuas yog ib tug hloov magnetic teb yuav tsim ib tug tam sim no nyob rau hauv lub thib ob.
transformer nce voltage li cas?
Transformers tsuas yog ua haujlwm nrog kev hloov tam sim no. Tias yog vim li cas nws yog qhov hloov pauv ntawm cov hlau nplaum tsim los ntawm thawj kauj uas induces voltagenyob rau hauv lub kauj thib ob. Txhawm rau tsim kom muaj qhov hloov pauv sib nqus, qhov hluav taws xob siv rau lub hauv paus kauj yuav tsum hloov tas li.
3 hom transformers yog dab tsi?
Nyobyog peb yam tseem ceeb ntawm voltage transformers (VT): electromagnetic, capacitor, thiab optical. Lub tshuab hluav taws xob hluav taws xob hluav taws xob yog lub tshuab hluav taws xob hloov hluav taws xob. Lub capacitor voltage transformer siv lub capacitance muaj peev xwm divider thiab yog siv nyob rau hauv high voltages vim tus nqi qis dua ib tug electromagnetic VT.
