Ib qho -theem fais fab transformer yog qhov tseem ceeb uas txhua hnub tus phab ej hauv cov tshuab hluav taws xob- nws ntsiag to theem voltage nce lossis nqis yog li peb tuaj yeem siv hluav taws xob tiag tiag yam tsis muaj peb cov khoom siv hluav taws xob lossis nkim hluav taws xob mus ntev.
Hauv cov ntsiab lus yooj yim, nws yog ib qho cuab yeej siv ib zaug -theem AC fais fab (hom feem ntau lub tsev tau txais) thiab hloov qhov voltage thaum ua kom qhov zaus zoo ib yam. Tsis muaj qhov txav txav, tsis muaj khawv koob- tsuas yog siv cov hlau nplaum thiab cov coils ntse.
Nws Tiag Tiag
Daim duab ob lub coils ntawm hlau (ib lub hauv paus, ib qho thib ob) qhwv ib ncig ntawm cov tub ntxhais hlau sib koom. Thawj kauj txuas mus rau koj lub zog tuaj, thiab qhov thib ob mus rau qhov twg xav tau qhov hloov kho voltage. Cov tub ntxhais feem ntau yog ua los ntawm nyias laminated silicon steel los xij stacked ua ke - qhov no txo qis zog poob los ntawm eddy tam sim no thiab hysteresis.
Nws yog txoj kev yooj yim dua thiab pheej yig dua li peb -theem versions, uas yog vim li cas nws zoo meej rau cov khoom uas tsis xav tau lub zog loj.
Nws ua haujlwm li cas (Tsis Tau Txais Phau Ntawv Qhia dhau lawm-y)
Nws tag nrho boils mus rau electromagnetic induction (ua tsaug, Faraday). Nov yog qhov ceev ceev:
Koj pub alternating tam sim no rau hauv thawj winding.
Uas AC tsim ib qho kev hloov pauv tsis tu ncua ntawm magnetic teb nyob rau hauv cov tub ntxhais.
Qhov chaw sib nqus "txuas" mus rau qhov thib ob winding thiab induces ib qhov hluav taws xob muaj - tsis muaj hluav taws xob txuas ncaj qha ntawm ob lub coils.
Qhov tso zis voltage nyob ntawm qhov sib piv: ntau lem ntawm theem nrab=siab dua voltage (theem-up); tsawg dua=qis (qib- nqis).
Ua tau zoo heev vim tias yuav luag tsis muaj zog poob raws li cov cua sov lossis kev siv tshuab- feem ntau cov khoom zoo khiav ntawm 95-99% efficiency.
(Yog tias koj pom, xav txog cov duab kos duab: thawj kauj ntawm ib sab ntawm cov tub ntxhais, theem nrab ntawm lwm qhov los yog concentric, nrog cov kab flux looping los ntawm cov hlau.)
Qhov tseem ceeb
Core- txoj kev sib nqus, laminated kom poob qis.
Thawj winding- tau txais lub zog nkag.
Secondary winding- muab lub zog hloov pauv.
Rwb thaiv tsev- khaws txhua yam los ntawm luv luv (tseem ceeb heev rau kev nyab xeeb).
Qee zaum koj yuav pom cov khoom ntxiv xws li cov kais dej rau kev hloov pauv hluav taws xob lossis cov fins txias / roj rau cov chav loj dua.
Hom Hom
Kauj ruam - nqes- Feem ntau hauv cov tsev: siv cov hluav taws xob hluav taws xob siab (xws li 11kV) mus rau 120/240V rau qhov hluav taws xob thiab khoom siv.
Kauj ruam - nce- Siv qee zaus hauv kev sib kis lossis kev teeb tsa tshwj xeeb los txhawb qhov voltage.
Kev rho tawm transformers- Feem ntau rau kev nyab xeeb, lawv cais cov hluav taws xob hauv hluav taws xob thaum hloov hluav taws xob sib nqus.
Qhov Koj Pom Lawv Hauv Lub Neej Tiag
Zoo nkauj heev nyob txhua qhov chaw ib zaug -theem fais fab yog tus qauv:
Chaw nyob- Ncej-mounted lossis ncoo-mounted transformers sab nraum tsev, nqis nqis hluav taws xob hluav taws xob rau lub teeb, tub yees, AC units, TVs, thiab lwm yam.
Lub teeb coj mus muag- Cov khw me, chaw ua haujlwm, tsev noj mov rau teeb pom kev zoo, khoos phis tawj, HVAC, cov tshuab me.
Cov cheeb tsam nyob deb nroog- Feem ntau mus- mus rau tej liaj teb los yog tej thaj chaw deb qhov chaw peb -theem tsis siv tau.
Rov ua dua tshiab- Hauv kev teeb tsa hnub ci, lawv pab sib piv cov zis inverter rau hauv tsev / kab hluav taws xob.
Txoj kev teeb pom kev zoolos yog me me tswj systems.
Yeej, yog tias nws tsis yog lub Hoobkas loj nrog cov motors hnyav, ib qho -theem transformers tej zaum yuav tuav nws.
Tib-Phase vs. Peb-Phase (Quick Comparison)
Ib zaug -theem yooj yim dua, pheej yig dua, thiab zoo rau qis zog (tsev, lag luam me). Peb -theem tswj txoj kev thauj khoom ntau dua, kev ua haujlwm zoo dua rau cov motors loj / kev lag luam, tab sis nws nyuaj thiab kim dua. Cov tsev feem ntau tau txais ib zaug -theem; factories tau peb -theem.

Xaiv Qhov Zoo Thiab Ua Kom Zoo Siab
Thaum xaiv:
Txheeb xyuas qhov xav tau qhov hluav taws xob hauv / tawm thiab lub zog ntsuas (kVA).
Xav txog ib puag ncig (hauv tsev / sab nraum zoov, plua plav, ntub dej?).
Qhov loj / qhov txwv.
Kev saib xyuas yog ncaj nraim: kev kuaj pom tsis tu ncua, ntxuav bushings, saib xyuas cov roj yog tias nws yog roj- puv, saib xyuas kom muaj cua sov lossis suab nrov txawv. Ua raws li txoj cai kev nyab xeeb- muaj hluav taws xob siab sab hauv, yog li tsis txhob cuam tshuam yam tsis muaj kev cob qhia kom raug.
Saib tom ntej, peb tab tom pom "ntse" transformers nrog sensors rau kev saib xyuas tej thaj chaw deb, cov ntaub ntawv zoo dua rau kev ua tau zoo dua, thiab cov qauv tsim rau kev siv dua tshiab / microgrids.
Hauv luv luv, ib qho -theem fais fab transformers yog qhov txhim khu kev qha, tsis muaj -fuss workhorses ua rau peb lub tsev thiab cov lag luam me muaj kev nyab xeeb thiab ua tau zoo. Lawv tsis flashy, tab sis yog tsis muaj lawv, lub neej txhua hnub yuav dimmer ntau (hais lus). Yog tias koj muaj ib qho kev teeb tsa tshwj xeeb lossis lus nug txog ib qho, thov koj xav qhia cov ntsiab lus ntxiv.
