Toroidal transformer: txhua yam koj yuav tsum paub

toroidal transformer

lub hloov dua siab tshiab (zoo li toroidal transformer) yog yam dav siv nyob rau hauv ntau cov khoom siv. Tshwj xeeb tshaj yog nyob rau hauv cov uas siv DC, txij li lawv tso cai los ntawm qhov hluav taws xob ntau ntawm cov hluav taws xob hluav taws xob uas cov khoom siv no txuas nrog rau cov hluav taws xob qis uas lawv feem ntau ua haujlwm (12v, 5v, 3.3v ...) thiab tom qab ntawd hloov los ntawm AC rau CC siv tas cov theem ntawm a fais fab mov.

Nws qhov tseem ceeb yog qhov uas koj yuav tsum paub nws ua haujlwm li cas hom transformers thiab lawv cov kev siv, nrog rau qhov twg thiab yuav ua li cas koj tuaj yeem yuav ib qho ntawm lawv rau koj cov dej num, thiab lwm yam. Txhua qhov kev tsis ntseeg yuav raug daws nrog phau ntawv qhia no ...

Dab tsi yog ib tug transformer?

daim duab pauv hloov

Un transformer Nws yog ib qho khoom siv uas tso cai kis los ntawm kev hloov tam sim no rau ib qho sib txawv. Nws tuaj yeem hloov qhov kev siv tam sim no. Ua li cas, nws yuav nco ntsoov khaws cov teeb liab zaus thiab lub hwj huam tseem ceeb rau kom ua. Ntawd yog, isofrequency thiab isopower ...

Qhov kawg ntsuas no tsis tuav qhov tseeb, nws yuav nyob rau hauv qhov zoo theoretical transformer, txij li thaum hauv kev xyaum muaj poob rau hauv daim ntawv ntawm tshav kub, ib qho teeb meem loj tshaj plaws ntawm cov khoom siv no. Tias yog vim li cas nws tau ploj mus los ntawm kev siv cov ntawv ruaj ruaj rau laminar lawv (silicon steel los xij nrog rwb thaiv tsev nruab nrab ntawm lawv) kom txo tau cov dej ntws tawm tam sim no los sis cov dej tsis sib haum.

Yuav kom ua tiav nws lub hom phiaj, hluav taws xob uas nkag los ntawm nws cov kev sib hloov winding yog hloov mus rau hauv hlau nplaum vim yog lub winding thiab hlau tub ntxhais. Tom qab ntawd, cov hlau nplaum hluav taws xob uas ntws los ntawm cov xim hlau tseem ceeb yuav ua rau muaj qhov tam sim no lossis hluav taws xob nyob rau hauv lub caij hloov thib ob kom muab cov lus hais tam sim no ntawm nws cov zis. Ntawm chav kawm, cov hlau xaim ntawm cov kab xaim muaj ib hom ntawm cov kua roj insulating yog li ntawd, txawm tias lawv tau mob, lawv tsis ua los sib chwv.

Txoj hauv kev hloov ntawm ib qho hluav taws xob mus rau lwm qhov yog ua si nrog tus naj npawb ntawm lem los yog lem ntawm tooj liab hlau hauv thawj thiab theem pib winding. Raws li Lenz Txoj Cai, qhov tam sim no yuav tsum tau hloov pauv rau cov kev hloov hluav taws xob no kom tshwm sim, yog li ntawd tus hloov hluav taws xob tsis tuaj yeem ua haujlwm nrog tam sim no ncaj qha.

Raws li koj tuaj yeem pom hauv daim duab saum toj no, txoj kev sib txheeb Nruab nrab ntawm lub coils qhov voltage thiab siv hluav taws xob yog yooj yim heev. Qhov twg N yog tus naj npawb ntawm lem ntawm lub voos xwm yeem (P = thawj, S = theem nrab), thaum V yog qhov voltage (P = thov rau tus thawj, S = tso tawm los ntawm theem nrab), lossis kuv sib npaug rau cov tam sim no ...

por Piv txwv li, Xav txog tias koj muaj transformer nrog 200 qwj nyob rau hauv thawj thiab 100 spirals nyob hauv theem nrab. Qhov ntsuas hluav taws xob ntawm 200v yog thov rau nws. Dab tsi voltage yuav tshwm sim ntawm cov zis ntawm theem nrab? Yooj yim heev:

200/100 = 220 / V

2 = 220 / v

v = 220/2

v = 110v

Ntawd yog hais, nws yuav tau pauv qhov hloov pauv 220v rau 110v ntawm nws cov txiaj ntsig. Tab sis yog tias tus naj npawb ntawm lem tau rov qab rau hauv thawj thiab theem nrab winding, qhov thim rov qab yuav tshwm sim. Piv txwv li, xav txog tias qhov qub 220v hluav taws xob hluav taws xob tau siv rau tus thawj, tab sis lub hauv paus muaj 100 lem thiab theem ob muaj 200 lem. Rau cov ua lag luam qhov no:

100/200 = 220 / V

0.5 = 220 / v

v = 220/0.5

v = 440v

Raws li koj tuaj yeem pom, hauv qhov no qhov voltage tau muab ob npaug ...

Yuav ua li cas ib tug toroidal transformer?

daim duab hluav taws xob

Txhua yam hais rau lub transformer pa tseem siv tau rau toroidal transformer, txawm hais tias qhov no nws muaj qee qhov sib txawv, raws li muaj qee qhov txiaj ntsig. Tab sis tus txheej txheem ua haujlwm thiab kev laij lej tuaj yeem pab koj nkag siab tias nws ua haujlwm li cas.

Hauv cov duab geometry, lub qhov rooj sib zog yog qhov saum npoo ntawm tig los ntawm polygon lossis ib qho yooj yim kaw dav hlau nkhaus uas tig ib ncig ntawm txoj kab coplanar sab nrauv uas nws tsis sib tshuam. Ntawd yog, hauv cov lus yooj yooj yim, nws yog hom lub nplhaib, donut, lossis hula hoop.

Lub tshuab hluav taws xob ib leeg hloov hluav taws xob tuaj yeem lav cov qis qis flux, thiab poob raws li qhov ua tsis tau me eddy dej tsaws ntxag dua li nyob rau hauv ib cov pa transformer. Yog li lawv yuav ua kom sov dua thiab ua tau zoo dua, ntxiv rau qhov muaj ntau dua vim lawv qhov zoo.

Zoo li cov pa hloov cav, lawv kuj tseem muaj thiab ntau tshaj ob kab yas, uas yuav ua rau tib co kauj, thiab ob peb lub coils tawm, txhua tus tuaj yeem hloov mus rau lwm qhov sib txawv. Piv txwv li, xav txog qhov muaj ob, ib qho uas mus rau ntawm 220v txog 110v thiab ib qho uas mus ntawm 220v mus rau 60v, uas yog qhov tswv yim zoo rau cov khoom siv fais fab uas ntau qhov kev hloov hluav taws xob xav tau.

Hauv qhov no, tsis txhob siv lub sib nqus Sab hauv cov plaub fab xwm fab ua xim hlau tub ntxhais, ua kom pom lub voj voog yog tsim tawm hauv lub qhov muag. Sab nraud ntawm nws daim teb yuav xoom, lub zog ntawm daim teb no tseem yuav yog nyob ntawm tus naj npawb ntawm lem.

Lwm qhov tsis zoo yog tias daim teb Nws tsis yog kev sib tsoo, yog muaj zog tshaj plaws sab hauv ntawm lub nplhaib thiab sab nraud tsis muaj zog tshaj sab hauv. Qhov ntawd txhais tau tias daim teb yuav tsawg zuj zus thaum lub vojvoog tawg.

Tus piv ntawm lub hwj chim cov tswv yim thiab cov khoom sib txawv txav raws li qhov loj me thiab kev ua haujlwm, tab sis yuav luag ib txwm muaj siab dua li cov pa hloov pauv. Tsis tas li ntawd, txij thaum lub zog tsis kam ntawm lub tshuab hloov hluav taws xob los ntawm cov xaim tooj liab ntawm cov coils thiab qhov poob ntawm qhov tseem ceeb, thiab txij li lub toroid muaj qhov poob qis, nws yuav ua tau ntau dua li kuv twb tau hais ua ntej.

Aplicaciones

lub daim ntaub ntawv lossis siv lawv zoo ib yam li cov pa hloov pauv. Lub tshuab hluav taws xob hloov pauv feem ntau yog siv ntau hauv kev lag luam hauv kev sib txuas lus, kev seev suab paj nruas, cov cuab yeej siv kho mob, cov tshuab hluav taws xob, thiab lwm yam.

Qhov zoo thiab qhov tsis zoo

Raws li ib txwm muaj tas li, qhov hloov pauv toroidal muaj nws qhov zoo, tab sis kuj tseem muaj qee qhov tsis zoo. Nyob nruab nrab ntawm qhov zoo sawv tawm:

  • Lawv ua tau zoo dua.
  • Rau tib lub inductance li ib txwm solenoid, lub toroid yuav xav tau tsawg dua lem, yog li ntawd nws yog qhov ntau dua.
  • Los ntawm muaj lub sib nqus teb sib xyaw nyob hauv lawv, lawv tuaj yeem tso ze rau lwm cov khoom siv hluav taws xob tsis muaj kev cuam tshuam los ntawm qhov tsis muaj qhov xav tau.

Ntawm cov tsis zoo Lawv yog:

  • Lawv muaj cov cua ntau tshaj qhov ib txwm muaj.
  • Nws tseem yog qhov nyuaj los kho lub cev.

Qhov twg yuav ib qho toroidal transformer

Koj tuaj yeem pom lawv yuav luag txhua qhov chaw khw hauv hluav taws xob tshwj xeeb, lossis koj tseem tuaj yeem nrhiav tau ntawm Amazon. Piv txwv, ntawm no yog qee qhov kev pom zoo:

Raws li koj tau pom, lawv txawv VA, 100VA, 300VA, thiab lwm yam. Cov nqi no hais txog qhov nyiaj siab tshaj uas tau tso cai. Thiab nws tau ntsuas hauv volts ib ampere.
