Electronic Transformer

Qee lub zog hloov hluav taws xob tau siv rau hauv kev tsim cov chaw nres tsheb, cov chaw nres tsheb thiab cov kab hluav taws xob xa mus rau kev nqis los yog nce mus txog qhov hluav taws xob. Los ntawm kev siv cov kauj ruam-up fais fab transformer, theem voltage nyob rau hauv cov kab kis tau tus mob yog nce, yog li tsis tshua muaj tam sim no ntws los ntawm txoj kab. Yog li ntawd, I2R poob hauv cov kab sib kis tau txo qis. Cov kauj ruam-down fais fab transformers yog siv los muab cov khoom thauj hauv kev lag luam ntawm nws qhov ntsuas voltages.
Qee lub hwj chim transformers kuj muab lub zog rau cov hluav taws xob hluav taws xob. Lub hwj chim transformer tuaj yeem ua ib zaug lossis peb theem raws li daim ntawv thov nws ua haujlwm rau. Nrog rau cov yam ntxwv tshwj xeeb ntawm kev hloov pauv hloov pauv, nws pib hloov pauv thiab faib hloov pauv feem ntau yog cov tsev neeg ntawm lub zog hloov pauv. Qee lub zog transformers tau tham hauv qab no.

Cov no feem ntau siv transformers thiab muaj los ntawm milliwatts mus rau megawatts ntau. Cov hom transformers no yog siv nyob rau hauv hluav taws xob kis tau tus mob thiab kuj nyob rau hauv cov khoom siv los muab qhov tsawg voltage. Qhov no transformer muaj ib tug laminated core los txo cov eddy tam sim no. Cov laminations no yog clamped ua ke nrog bolts. Ob qho tib si thawj thiab theem nrab windings raug mob ntawm ib tug qub thiab muab tso rau ib ncig ntawm lub hauv paus ceg ntawm lub hauv paus. Cov transformers no siv phua bobbin los muab cov rwb thaiv tsev siab ntawm cov windings rau cov khoom siv me me. Nruab nrab ntawm thawj thiab theem nrab, cov ntaub thaiv npog yuav raug siv los txo qhov cuam tshuam ntawm electromagnetic.
Hom transformer no muaj ntau yam zoo dua laminated core transformer uas nws muab kev ua haujlwm zoo thiab muaj txiaj ntsig nrog txo qis los yog sab nraud sib nqus. Vim qhov hnyav tsawg thiab me me, cov no tau yooj yim tsim rau txhua daim ntawv thov kev khiav hauj lwm qis lossis siab voltage. Ib qho zoo heev donut zoo li tus tub ntxhais yog siv uas yog tsim los ntawm grain oriented silicon hlau thiab raug txiav los ua ib tug ribbon ntawm hlau. Cov tub ntxhais no txuas ntxiv qhwv los ntawm tooj liab windings zoo li lub caij nplooj ntoo hlav nruj heev. Piv rau EI laminated core transformer, toroidal core transformers yog kim dua. Txawm li cas los xij, rau qhov kev ntsuam xyuas me me thiab sib dua yuav yog toroidal transformer piv nrog EI laminated hom transformer. Tsis tas li ntawd, nws muab cov xau tsawg ntawm cov hlau nplaum thiab ua haujlwm ntau dua. Cov no muaj los ntawm ob peb kaum ntawm VA's mus rau txhiab VA's. Feem ntau, lawv tuaj nrog qhov nruab nrab ib lub qhov mounting los ntawm ib tug ntsia liaj qhov rooj nrog washers thiab roj hmab pads.

Nws pib transformers txawv ntawm tus qauv ob los yog peb winding transformer raws li nws muaj tsuas yog ib qho winding uas ua raws li thawj thiab theem nrab. Nyob rau hauv no, ib feem ntawm no ib leeg winding yog ib qho rau ob qho tib si thawj thiab theem nrab thiab li no cov hluav taws xob txuas (ob windings yog hluav taws xob cais nyob rau hauv cov ntaub ntawv ntawm ib txwm transformer). Yog li no transformer ua haujlwm ntawm conduction thiab induction. Nyob rau hauv no, ib tug laminated core yog mob los ntawm ib tug winding thiab ib feem ntawm no winding yog muab faib ua thawj thiab thib ob.
Cov no tau muab faib ua cov kauj ruam-up thiab kauj ruam-down pib transformer. Nyob rau hauv kauj ruam-down pib transformer, tag nrho winding ua raws li thawj thiab ib feem ntawm nws ua raws li theem nrab thiab li no voltage induced nyob rau hauv lub thib ob yog tsawg li piv nrog thawj. Ntawm qhov tod tes, thim rov qab yuav yog rooj plaub rau lub kauj ruam-up transformer. Peb theem fais fab transformers yog siv nyob rau hauv lub hwj chim tis systems uas yuav yog hnub qub los yog delta txuas nrog nws pib transformers. Tab sis feem ntau lub hnub qub txuas nrog nws pib transformers yog siv rau kev siv hluav taws xob siab.
Nws pib hloov pauv hloov pauv tuaj nrog tus lej tappings ntawm ib qho winding thiab txuas txuas txuas nrog cov zawv zawg carbon txhuam. Yog li ntawd, los ntawm zawv zawg cov pa roj carbon txhuam qhov sib txawv voltage yog tsim nyob rau hauv theem nrab uas yog sib npaug rau qhov sib piv ntawm tag nrho cov winding thiab tapping.
Nws pib transformers yog siv los ua stators rau kev nyab xeeb pib ntawm ntau lub tshuab hluav taws xob xws li synchronous motors, induction motors, thiab lwm yam. Thiab cov no kuj siv los ua qhov cub hluav taws xob transformers thiab boosters.

Hom transformer no feem ntau ua haujlwm rau peb theem hluav taws xob hluav taws xob xws li cov phiaj xwm hluav taws xob thiab cov kab sib txuas uas lawv hloov cov hluav taws xob ntau ntau. Cov no yog cov kev lag luam tshaj plaws vim kev siv dav ntawm peb theem AC tiam, kev sib kis, kev faib tawm thiab kev siv tshuab. Hom transformer no muaj peb windings uas raug mob nyob ib ncig ntawm peb legged core thiab raus rau hauv ib lub tank. Cov thawj thiab theem nrab windings tuaj yeem txuas nrog sib txawv ntawm kev sib txuas xws li lub hnub qub-hnub qub, lub hnub qub-delta, delta-delta thiab delta-hnub qub. Cov no tuaj yeem yog cov kauj ruam nce lossis nqis nqis peb theem transformers nyob ntawm daim ntawv thov lossis kev thauj khoom. Vim yog cov tseem ceeb rau tag nrho cov windings, qhov tsawg dua yuav yog cov sib nqus nqus flux thiab li no efficiency ntawm lub transformer yog siab.

Roj txias transformer yog cov fais fab loj loj siv nyob rau hauv ntau chav nyob ntawm qhov chaw tsim hluav taws xob loj lossis cov chaw ua haujlwm substation mus rau cov khoom siv hluav taws xob. Cov transformers no tau ntim nrog cov qauv hloov pauv roj (lossis cov roj ntxhia) los muab cov cua txias nrog rau kev rwb thaiv tsev rau cov windings thiab cov tub ntxhais. Nyob rau hauv cov roj txias transformers, core thiab coils yog submerged los yog immersed nyob rau hauv cov kua los yog roj. Raws li piv rau cov cua txias transformers, roj muab cov rwb thaiv tsev zoo dua thiab ua raws li tus neeg xyuas pib zoo dua ntawm cov cua sov.
RF transformers yog siv nyob rau hauv ib tug ntau yam ntawm hluav taws xob circuits rau ntau yam xws li impedance txuam mus rau lub siab tshaj plaws hwj chim, DC kev rho tawm ntawm lub circuits, voltage thiab tam sim no step-up los yog step-down, interfacing ntawm unbalanced thiab balanced circuits, thiab lwm yam. tuaj raws li cov pob khoom txuas, pob khoom saum npoo av thiab lwm yam kev teeb tsa sib txawv. Cov hlau laminations tsis siv rau RF transformers. Kev ua haujlwm zaus ntawm qhov hloov pauv no yog nyob ntawm 30 KHz txog 30 MHz thiab feem ntau yog los ntawm kev sib ntxiv ntawm capacitor rau ib qho winding pab kho lawv cov windings rau ib qho zaus.
Cov no tuaj yeem yog cua core, ferrite core, balun hom transformers. Cua tub ntxhais RF transformers siv nyob rau hauv cov ntawv luam Circuit Court boards xws li ob peb lem ntawm ib tug hlau yog soldered rau nws. Ferrite core transformers yog siv nyob rau hauv superheterodyne xov tooj cua receivers uas feem ntau tuned hom transformers. Balun transformers yog siv los txuas cov kev sib txuas tsis sib xws thiab sib npaug xws li cov khoom siv hluav taws xob sib npaug (kev siv hom kev tsis lees paub ntau yam).

Audio transformers yog tshwj xeeb tsim transformers siv los nqa lub teeb liab hauv suab circuits. Kev ua haujlwm zaus yog li ntawm 20 Hz txog 20 KHz rau hom transformer no. Cov no yog siv rau kev ua haujlwm ntau yam xws li kev nce lossis nqis los ntawm cov teeb liab voltage, hloov lub voj voog los ntawm kev sib npaug mus rau qhov tsis sib npaug thiab rov ua dua, txo qis lossis nce impedance ntawm Circuit Court, thaiv DC tivthaiv tam sim no thiab tso cai rau AC teeb liab, thiab muab hluav taws xob galvanic cais tawm ntawm ib lub suab mus rau lwm qhov. Cov hom transformers muaj xws li microphone input, line input, txav-coil phono input, kab tso zis, inter-theem thiab lub zog tso zis, microphone tso zis, splitter, impedance conversion, ncaj lub thawv, Hum eliminators, loudspeaker toroidal AF transformers, thiab lwm yam.
