Utility Nce Transformers, Qhov tseeb, yog ncej faib khoom xa hluav taws xob yog kom txo qis qhov hluav taws xob kom nws ua tau raws li cov khoom siv hluav taws xob.
Lub ntsiab kev sib sau ntawm kauj ruam -} down transformers
Haum rau cov khoom uas yuav tsum muaj: cov khoom siv hluav taws xob sib txawv thiab cov tshuab muaj ntau yam voltage yuav tsum muaj. Lub zog hloov hluav taws xob tuaj yeem hloov siab dua {1} {voltage hluav taws xob rau hauv qis- down down-}} Cov khoom siv tshwj xeeb los yog ua kom muaj kev ua haujlwm ib txwm ua. Piv txwv li, qis {- voltage cov khoom siv thiab siab}}} {}}}} pa taws poles yog ib feem ntawm lub zog hluav taws xob. Vim kev sib kis, lawv cov khoom siv hluav taws xob siab dua li cov cuab yeej hluav taws xob txhua hnub, tab sis peb cov khoom siv hluav taws xob txhua hnub, yog li cov khoom siv hluav taws xob txhua hnub, yog li tam sim no yuav tsum tau nqis.
Hauv kev ua haujlwm txhua hnub thiab lub neej, tus cwj pwm no txuas lub zog hluav taws xob rau lub tshuab hluav taws xob siab rau kev faib tawm, thiab cov muag khoom xa tuaj yeem kuj tau muab tau los ntawm. Hauv kev faib tawm, lub zog hloov pauv tuaj yeem hloov lub siab-} {voltage hluav taws xob haum rau lub tsev thiab kev siv hluav taws xob hauv tsev thiab kev siv. Los ntawm kev siv kauj ruam - down fais fab hloov hluav taws xob (Nyem txhawm rau paub txog kauj ruam -} down transformers), Peb tuaj yeem ntseeg tau tias cov neeg siv kawg siv cov khoom siv hluav taws xob kom nyab xeeb. (Yawiei Transformer tuaj yeem muab cov kev pab sab laj muaj zog thiab kev txawj ntse Engineering)
Tus ua hauj lwm ua haujlwm ntawm transformer
Tus ua haujlwm ua haujlwm ntawm cov hloov pauv yog hluav taws xob induction, tab sis nruj me ntsis kev hais lus, nws yog vim kev sib nrig sib hais lus tsis meej. Cov hauv qab no yog kev piav qhia ntawm txoj cai induction thiab kev sib nrig sib tham induction ua:
Lub hauv paus ntsiab lus ntawm indectromagnetic induction: thaum sib nqus flux txuam nrog kev hloov pauv ntawm lub cev (lossis thaum lub zog hluav taws xob hloov pauv tsis tu ncua raug tsim tawm tas li. Nov yog qhov kev piav qhia zoo tshaj plaws ntawm "Electromagnetism".
Tshwj xeeb, raws li kev sib tw induction lub hauv paus, qhov tam sim no ua rau lub zog hluav taws xob (tsis muaj qhov sib tw ntawm kev hloov pauv ntawm flux sib nqus dhau los ntawm cov kauj. Peb tuaj yeem piav qhia cov lus no ntau intuitively hauv kev ua lej,
, where e yog qhov ua rau lub zog hluav taws xob, n yog tus naj npawb ntawm lem ntawm lub kauj, thiab
yog tus nqi ntawm kev hloov ntawm cov sib nqus flux.
Cia peb saib ntawm kev sib nrig sib: Hloov cov kauj vab tam sim no hauv cov kauj hauv theem nrab, thiab hloov cov hlau sib nqus hauv cov kauj hauv theem nrab, thiab hloov pauv tam sim no: EMF. Kev sib nrig sib cai yog qhov txiaj ntsig ncaj qha ntawm Faraday Txoj Cai.
Transformers yog qhov piv txwv zoo tshaj plaws ntawm kev sib nrig sib, thiab peb txhais tau tias yog hu ua ib qho kev hloov pauv hluav taws xob (uas peb feem ntau hu "hluav taws xob ua rau muaj hluav taws xob), hlau nplaum tsim hluav taws xob").
Hauv kev nthuav dav, kev tsim tawm Lenz txoj cai lij choj, tam sim no los ntawm kev sib nrig sib cuam tshuam ntawm ob coils (m) Kev sib nrig sib los ntawm ob coils yog tib yam.

Cov FAQ
Q: 1. Koj tuaj yeem xa tus hloov pauv sai sai sai npaum li cas?
A: Nws nyob ntawm qhov ntau thiab muaj peev xwm ntawm kev hloov pauv, feem ntau nyob hauv ib hlis txij li hnub kos duab paub tseeb los ntawm tus neeg yuav khoom.
Q: 2. Ntev npaum li cas tuaj yeem muab cov khoom lag luam zoo?
A: 24 lub hlis txij li hnub hloov pauv ua haujlwm.
Q: 3. Dab tsi them txoj kev them nyiaj?
A: T / T (Hlau Hloov) nyiam, L / C ob qho tib si txais.
