Ntawm cov poob ntawm covtransformer, muaj ob feem ntau: hlau poob thiab tooj liab poob. Yog li, qhov sib txawv ntawm cov hlau poob thiab tooj liab poob ntawm lub transformer yog dab tsi?
Cov hlau poob ntawm lub transformer yog qhov poob los ntawm cov tub ntxhais hlau nyob rau hauv lub transformer, thiab tooj liab poob ntawm lub transformer yog ib tug load poob.
1. Hlau poob ntawm transformer
Hlau poob, tseem hu ua tsis muaj load poob, yog ib qho kev poob ntawm lub transformer. Nws yog qhov poob los ntawm cov tub ntxhais hlau hauv lub transformer, yog li nws tseem hu ua core poob.
Hlau poob yog hais txog lub zog siv nyob rau hauv cov tub ntxhais hlau ntawm lub transformer ntawm qhov ntsuas hluav taws xob (secondary open circuit), suav nrog hysteresis poob thiab eddy tam sim no poob.
Transformer hlau poob muaj xws li:
1) Hysteresis poob
Thaum alternating tam sim no dhau los ntawm lub transformer, cov kev taw qhia thiab qhov loj ntawm cov kab hlau nplaum dhau los ntawm silicon steel nplooj ntawv ntawm lub transformer hloov raws li, ua rau cov molecules nyob rau hauv lub silicon steel los xij mus rub tawm ib leeg thiab tso tawm lub zog tshav kub, yog li poob ib feem ntawm. lub zog hluav taws xob. Qhov no yog hysteresis poob.
2) Eddy tam sim no poob
Thaum lub transformer ua haujlwm, muaj cov kab sib nqus ntawm lub zog dhau los ntawm cov tub ntxhais hlau, thiab qhov cuam tshuam tam sim no yuav raug tsim tawm ntawm lub dav hlau perpendicular rau cov kab sib nqus ntawm lub zog. Txij li qhov tam sim no tsim ib lub voj kaw los ua ib qho kev ncig thiab dhau los ua vortex, nws yog hu ua eddy tam sim no.
Qhov muaj nyob ntawm eddy tam sim no ua rau cov tub ntxhais hlau ua kom sov thiab siv zog. Qhov kev poob no yog hu ua eddy tam sim no poob.
2. Copper poob ntawm transformer
Cov tooj liab poob ntawm lub transformer kuj hu ua lub load poob.
Copper poob (luv luv Circuit Court poob) yog hais txog cov lej ntawm lub zog poob los ntawm thawj thiab theem nrab tam sim no ntawm transformer ntws los ntawm cov coil tsis kam. Txij li cov coils feem ntau yog ua los ntawm tooj liab hlau, lawv hu ua tooj liab poob.
Qhov tooj liab poob ntawm lub transformer yog proportional rau square ntawm tam sim no. Tus lej kilowatt cim rau ntawm daim ntawv teev npe yog hais txog qhov poob ntawm tooj liab thaum lub coil hla qhov ntsuas tam sim no ntawm 75 degree.
