Transformer Txoj Cai

Transformer yog ib yam khoom uas hloov AC voltage, tam sim no, thiab impedance. Thaum AC tam sim no dhau los ntawm thawj kauj, AC magnetic flux yog tsim nyob rau hauv cov tub ntxhais hlau (los yog cov tub ntxhais sib nqus), uas induces ib tug voltage (los yog tam sim no) nyob rau hauv lub thib ob kauj. Lub transformer muaj ib tug hlau core (los yog magnetic core) thiab ib kauj. Lub coil muaj ob los yog ntau tshaj windings. Lub winding txuas nrog lub hwj huam mov yog hu ua thawj kauj, thiab qhov seem windings yog hu ua lub kauj thib ob. Nyob rau hauv ib lub tshuab hluav taws xob, seb lub kauj txav mus los ntawm qhov chaw sib nqus los yog qhov chaw sib nqus txav los ntawm lub kauj ruaj ruaj, lub peev xwm hluav taws xob tuaj yeem raug ntxias hauv lub kauj. Nyob rau hauv ob qho tib si, tus nqi ntawm cov hlau nplaum flux tseem zoo ib yam, tab sis tus nqi ntawm cov hlau nplaum sib cuam tshuam cov kauj sib txawv. Hloov, qhov no yog lub hauv paus ntsiab lus ntawm kev sib nrig sib induction. Lub transformer yog ib qho khoom siv uas siv electromagnetic sib nrig sib inductance los hloov voltage, tam sim no thiab impedance.
