Transformer Coil Txoj Cai

Hauv cov khoom siv hluav taws xob thiab hluav taws xob hluav taws xob, cov khoom siv hluav taws xob feem ntau siv rau kev tswj hluav taws xob, kev sib txuam impedance, kev nyab xeeb kev sib cais, thiab lwm yam. Hauv cov tshuab hluav taws xob, txawm tias lub coil txav los ntawm cov hlau nplaum los yog cov kauj ruam, lawv tuaj yeem ua rau lub zog hluav taws xob hauv lub kauj. Nyob rau hauv ob qho tib si, tus nqi ntawm magnetic flux tseem tsis hloov, tab sis tus naj npawb ntawm magnetic flux intersecting lub coil hloov. Qhov no yog lub hauv paus ntsiab lus ntawm kev sib nrig sib inductance. Transformer yog ib qho khoom siv uas siv cov khoom siv hluav taws xob sib txuas ua ke los hloov qhov voltage, tam sim no, thiab impedance.
Daim ntawv yooj yim ntawm transformer muaj xws li ob txheej ntawm coils qhov txhab nrog cov xov hlau, uas yog inductively txuas rau ib leeg. Thaum AC tam sim no (nrog rau qee qhov kev paub zaus) ntws mus rau hauv ib qho ntawm cov coils, AC voltage nrog tib zaus yuav raug cuam tshuam rau lwm lub kauj, thiab qhov loj ntawm qhov induced voltage nyob ntawm qib ntawm kev sib txuas thiab sib nqus flux txuas. nruab nrab ntawm ob lub coils.

Feem ntau, lub kauj txuas nrog AC lub zog hluav taws xob yog hu ua thawj kauj; Qhov voltage hla lub kauj no yog hu ua thawj voltage. Lub induced voltage nyob rau hauv lub thib ob kauj yuav ntau dua los yog tsawg tshaj li lub thawj voltage, uas yog txiav txim los ntawm qhov ratio ntawm lem ntawm lub thawj kauj thiab lub thib ob kauj. Yog li ntawd, transformers yuav muab faib ua ob hom: step-up thiab step-down transformers.
Feem ntau cov transformers tau tsau hlau cores nrog thawj thiab theem nrab coils raug mob nyob ib ncig ntawm lawv. Raws li kev ua haujlwm siab ntawm cov khoom siv hlau, feem ntau ntawm cov hlau nplaum sib nqus yog txwv rau cov tub ntxhais hlau, yog li ntawd, ob pawg ntawm cov coils tuaj yeem ua tiav qib siab ntawm cov hlau nplaum sib txuas los ntawm qhov no. Hauv qee qhov kev hloov pauv, lub kauj thiab cov tub ntxhais hlau yog nruj me ntsis sib koom ua ke, thiab qhov sib piv ntawm lub hauv paus mus rau theem nrab voltage yuav luag zoo ib yam li qhov piv ntawm qhov hloov ntawm ob lub coils.
Yog li ntawd, qhov sib piv ntawm lub transformer feem ntau yuav siv tau los ua ib qho kev qhia rau kev txhawb nqa lossis txo qhov voltage hauv transformers. Vim muaj kev ua haujlwm ntawm kev txhawb nqa thiab txo qhov voltage, transformers tau dhau los ua ib qho tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub. Kev sib kis hluav taws xob ntau ntxiv ua rau kev xa hluav taws xob mus ntev kom txuag tau nyiaj ntau dua. Raws li cov kauj ruam-down transformers, lawv ua rau cov ntawv thov hluav taws xob ntau ntau. Nws tuaj yeem hais tias tsis muaj transformers, kev lag luam niaj hnub tsis tuaj yeem ua tiav txoj kev loj hlob tam sim no.
