Muaj ib lub koom haum qub tso dag. Rau lo lus nug ntawm tus kws qhia ntawv "Yuav ua li cas ib-theem transformer ua hauj lwm", tus tub ntxhais kawm buzzes teb: "Uuu!". Lub suab zoo li no tshwm sim tiag tiag, tab sis nws yog vim lub fact tias thaum lub inductive teb yog qhia, ib tug magnetic-striction nyhuv tshwm sim, ua rau cov daim hlau ntawm lub magnetic Circuit Court rau vibrate.

Ib theem ib-theem transformer yog tsim los muab tus nqi ntawm AC voltage rau lub load uas tsis xav tau peb-theem fais fab mov.

Ib qho kev hloov pauv muaj ob lub ntsiab: ib qho tseem ceeb thiab cov coils, muaj tsawg kawg yog ob ntawm lawv. Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog yooj yim. Raws li qhov tshwm sim ntawm qhov kev hla ntawm cov hluav taws xob tam sim no los ntawm tus neeg xyuas pib hauv thawj qhov cua, lub zog hluav taws xob (EMF) raug cuam tshuam rau theem nrab. Cov tub ntxhais muaj cov phaj ferromagnetic, uas yog, cov khoom siv uas txhim kho cov hlau nplaum (hluav taws xob hlau ntawm qib tshwj xeeb).

Tus nqi EMF yog txiav txim los ntawm tus qauv:

E=4, 44 x F x f x ω

qhov twg:

F –Sib nqus flux amplitude;

f - zaus tam sim no;

ω yog tus naj npawb ntawm tig hauv qhov cua.

Lub peev xwm tso cai tau lub zog uas ib-theem transformer yuav "rub" yog muab los ntawm ntu ntu ntawm cov hlau uas cov coils raug mob, thiab qhov zoo tshaj plaws ntawm cov hlau nplaum Circuit Court, tshwj xeeb tshaj yog, qhov sib nqus permeability. ntawm ferromagnet µ. Qhov luaj li cas ntawm cov tub ntxhais thiab tus naj npawb ntawm cov lem yog cov ntsiab lus ntawm kev suav, uas feem ntau yog cov ntsiab lus ntawm cov ntaub ntawv hauv cov tsev kawm txuj ci.

Txawm li cas los xij, lub zog hluav taws xob ib-theem hluav taws xob ntau dua, qhov ua tau zoo dua lawv qhov loj. Ntawm lawv cov ntaub ntawv, feem ntau muaj ib daim ntawv teev cov tsis tseem ceeb (tso cai tam sim no, input thiab output voltages). Txawm li cas los xij, qhov no tsis yog ib txwm muaj.

Hauv kev xyaum, ntau tus kws kho mob feem ntau ntsib nrog qhov xav tau los hloov qhov hluav taws xob hluav taws xob ib-theem hluav taws xob. Txhawm rau kom ntseeg tau tias tsim nyog, cov lus qhia tshwj xeeb ntawm cov cuab yeej hloov pauv yuav tsum raug tshuaj xyuas.

Thawj qhov uas yuav tsum tau ua yog txhawm rau txheeb xyuas qhov nkag winding. Rau cov kauj ruam-down transformers, nws muaj qhov ua haujlwm siab tshaj plaws.

Tom qab ntawd, los ntawm kev ntsaws rau hauv lub network, koj tuaj yeem ntsuas qhov tso zis hluav taws xob hauv hom tsis ua haujlwm. Qhov piv ntawm cov tswv yim thiab cov zis EMF yog qhov hloov pauv piv K. Nws kuj tseem sib npaug rau feem N hauv / N tawm, uas yog, tus naj npawb ntawm cov lem hauv windings.

Tom qab ntawd, koj tuaj yeem txuas lub zog sib txawv (rheostat) raws li kev thauj khoom thiab coj tus yam ntxwv tam sim no-voltage los ntawm kev txiav txim siab tus nqintsuas tam sim no. Raws li cov load nce, cov zis voltage maj mam poob.

Transformers tsis yog lub zog xwb, tab sis kuj ntsuas. Nyob rau hauv rooj plaub uas nws yog ib qho tsim nyog los txiav txim siab qhov tseem ceeb ntawm tam sim no hauv Circuit Court, siv ammeter. Nws yog kev cob cog rua nyob rau hauv series thiab yuav tsum muaj ib tug tsawg kuj ua ke nrog ib tug loj hlau gauge nyob rau hauv lub magnetic deflection system. Xws li ib tug ntaus ntawv yuav loj heev thiab kim, yog li ntawd, ib-theem tam sim no transformers yog siv, uas coj proportionally txo nqi thiab pub rau lawv mus rau lub zoo tib yam serial ammeters. Nws tsis yog qhov nyuaj los xam cov amperage, nws tsuas yog siv cov multipliers qhia ntawm rooj plaub.
