Qhuav transformers yog dav siv nyob rau hauv ntau yam kev siv hluav taws xob vim lawv cov kev ntseeg siab, kev nyab xeeb thiab yooj yim. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab ziab khaub ncaws qhuav yog raws li Faraday txoj cai ntawm electromagnetic induction, nyob rau hauv uas cov alternating tam sim no ntws los ntawm cov thawj winding generates ib magnetic teb thiab induces ib tug voltage nyob rau hauv lub thib ob winding.
Thawj winding ntawm aqhuav hom transformermuaj ib tug series ntawm insulated conductors uas raug mob nyob ib ncig ntawm ib tug hlau core ua los ntawm ib tug hlau nplaum, xws li laminated silicon steel. Qhov thib ob winding kuj yog ua los ntawm ib tug insulated conductor qhov txhab nyob ib ncig ntawm tib lub hlau nplaum, tab sis tus naj npawb ntawm lem yog txawv los ntawm cov thawj winding. Qhov ratio ntawm lem ntawm thawj thiab theem nrab windings txiav txim siab lub transformer tus transformer ratio.
Thaum AC voltage yog siv rau thawj winding ntawm lub transformer, ib tug sib nqus teb yog generated los ntawm cov hlau core thiab ib tug voltage yog induced nyob rau hauv lub thib ob winding. Lub induced voltage yog proportional rau tus naj npawb ntawm lem nyob rau hauv lub thib ob winding, thiab yog li ntawd mus rau lub transformer tus transformer ratio. Lub amplitude thiab zaus ntawm cov zis voltage nyob ntawm qhov input voltage thiab transformer tus transformer piv.
Cov tub ntxhais hlau nplaum ntawm lub tshuab hloov pauv qhuav yog tsim los txo qis hysteresis thiab eddy tam sim no poob, uas yog tshwm sim los ntawm cov khoom sib nqus ntawm cov khoom tseem ceeb. Hysteresis poob yog tshwm sim los ntawm magnetization thiab demagnetization ntawm cov khoom tseem ceeb thaum lub sij hawm AC lub voj voog, thaum eddy tam sim no poob yog tshwm sim los ntawm tam sim no induced los ntawm magnetic teb nyob rau hauv cov khoom tseem ceeb.
Rwb thaiv tsev ntawm qhuav-hom transformer yog ib qho tseem ceeb heev rau nws txoj kev nyab xeeb thiab txhim khu kev qha. Cov ntaub ntawv rwb thaiv tsev siv rau hauv cov khoom siv hluav taws xob yuav tsum muaj peev xwm tiv taus hluav taws xob siab, kub siab thiab ib puag ncig ib puag ncig ntev. Qhuav transformers muaj nyob rau hauv ntau hom rwb thaiv tsev, xws li lub tshuab nqus tsev impregnation, encapsulation thiab self-quenching polyester resins.
Piv txwv li, lub ntsiab lus ntawm kev ua haujlwmqhuav hom transformersyog raws li Faraday txoj cai ntawm electromagnetic induction, uas yog, alternating tam sim no ntws los ntawm cov thawj winding generates ib magnetic teb thiab induces ib tug voltage nyob rau hauv lub thib ob winding. Lub hauv paus tsim thiab rwb thaiv tsev ntawm lub transformer yog qhov tseem ceeb rau nws txoj kev nyab xeeb thiab txhim khu kev qha. Qhuav transformers yog dav siv nyob rau hauv ntau yam kev siv hluav taws xob vim lawv cov kev ntseeg siab, kev nyab xeeb thiab yooj yim.
