Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm ib qho kev hloov pauv yog raws li qhov tshwm sim ntawm tus kheej induction. Ib kauj ruam-down transformer yog xyaum tsis txawv los ntawm ib tug step-up ib. Nws yog txaus los hloov txoj kev sib txuas (tig lub caij dhau) thiab ib kauj ruam-up analog yuav tig tawm ntawm ib kauj ruam-down.
Hauv kev tswj Circuit Court, transformers yog siv los npaj galvanic cais, thaum ib theem thiab ib qho av xoom tuaj rau lub tswv yim ntawm lub cuab yeej, thiab qhov hluav taws xob tshwm sim ntawm cov zis yam tsis muaj qhov nruab nrab hauv av. Qhov no feem ntau yog siv los siv cov khoom siv logic logic.
Muaj cov kauj ruam-down transformers ib-theem, ob-theem thiab peb-theem. Muaj autotransformers thiab tam sim no transformers - tag nrho cov hom no tau ntse siv nyob rau hauv ntau qhov chaw ntawm lub zog kev lag luam.
Transformer - ib lub cuab yeej muaj ob lub windings nrog lub laminated core, uas yog recruited los ntawm hluav taws xob hlau. Yog tias tsim nyog los ua kom muaj kev sib cais ntawm cov pa galvanic, ces cov coils yuav tsum tau ua nrog tib tus naj npawb ntawm lem. Yog hais tias koj yuav tsum tau ua ib tug transformertxo qis, tus lej tig yuav txawv.
Voltage yog siv rau lub tswv yim ntawm lub cuab yeej (hauv qhov no, lub zog hluav taws xob tshwm sim nyob rau hauv winding, uas ua rau lub magnetic teb). Daim teb no hla lub lem ntawm ob kauj, qhov twg nws tus kheej electromotive quab yuam ntawm tus kheej induction tshwm sim. Nyob rau hauv lem, ib tug voltage kuj tshwm sim nyob rau hauv lub thib ob kauj, uas yuav txawv los ntawm lub hauv paus ib tug los ntawm tib yam li tus naj npawb ntawm lem ntawm ob windings.
Kev suav ntawm cov kauj ruam-down transformer yog qhov tsim nyog kom nkag siab tias qhov ntsuas ntawm lub cuab yeej yuav tsum yog dab tsi. Vim qhov tseeb tias EMF ntawm tus kheej induction tshwm sim vim txav mus los, lub transformer tsuas yog ua haujlwm ntawm kev hloov hluav taws xob xwb. Tias yog vim li cas hauv lub network hauv tsev - tsuas yog hloov tam sim no.
Hnub no, xws li ntau yam xws li cov kauj ruam-down transformer feem ntau yog siv. Rau feem ntau nws yog qhov yuav tsum tau hloov high voltage mus rau qis. Lawv yog siv nyob rau hauv cheeb tsam ntawm lub nroog hluav taws xob (ntawm substations thiab fais fab nroj tsuag). Chav turbines thiab hydroelectric units tsim hluav taws xob nrog kev cia siab ntawm kev muab lub zog rau ib qho chaw ntawm lub nroog, yog li nws yog ib qho tseem ceeb uas yuav tsum tau siv cov kauj ruam-down transformers kom qhov pib voltage nyob rau hauv txhua qhov ntawm cov seem yog hloov dua siab tshiab rau hauv ib qho kev lees txais. Cov kev xav tau hauv tsev.
Tab sis cov kauj ruam-down transformer feem ntau siv hauv tsev (kom hloov cov khoom siv hluav taws xob qis rau 220 volt network). Txog rau qhov kawg no, lawv tau siv hauv cov khoom siv hluav taws xob, hauv cov khoom siv hluav taws xob thiab txhua yam ntawm cov adapters, hauv stabilizers thiab lwm yam.khoom siv.
Thaum yuav lub tshuab hloov pauv, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas qhov ua tau zoo, lub zog thiab tus lej ntawm ob qhov windings. Muaj cov transformers nrog ob peb qhov tso zis (qhov no txhais tau hais tias ntau pab pawg ntawm kev sib txuas tau siv hauv cov cuab yeej thiab, nyob ntawm seb tus nqi ntawm cov khoom siv thiab cov khoom siv tawm, qhov xav tau Circuit Court yog tsim). Cov no yog universal transformers. Lawv kim me ntsis, tab sis lawv xav tau ntau.
Muaj transformers rau vuam. Boosting analogues yog siv ntawm no. Qhov no yog ua tiav txhawm rau tsim cov dej ntws uas tsim nyog los yaj cov hlau. Cov cuab yeej no kuj raug xaiv raws li qee qhov kev txwv. Qhov tseem ceeb, raws li koj xav, yog lub zog ntawm tam sim no.
