Yuav ua li cas yog transformer? Hom ntawm transformers. Lub hauv paus ntsiab lus ntawm transformer txiav txim

Nyob rau hauv no tsab xov xwm peb yuav saib dab tsi hauv lub transformer. Hom ntawm transformers yuav tau piav, lub hauv paus ntsiab lus ntawm kev txiav txim thiab tsim kuj tsis mus unnoticed. Nws yog ib nqi sau cia hais tias qhov no zoo ntawm zoo li qub (tsau) AC tshuab uas yog siv rau ntau yam ntawm cov hom phiaj, tsis tsuas yog nyob rau lub tsev tab sis kuj nyob rau hauv kev lag luam. Piv txwv li, dab tsi rau noj nqos tau cov hluav taws xob. Tiam sis ua ntej tej yam uas ua ntej.

Yuav ua li cas yog no ntaus ntawv?

Qhov no hluav taws xob zoo li qub tshuab, uas yog siv los hloov tam sim no los yog voltage. Thiab muaj ntau ntau hom ntawm pab kiag li lawm, nyob ntawm seb lub hwj chim yog los ntawm ib tug network. Yog li, peb-theem network muaj peb windings, uas yog muaj nyob rau hauv ib tug "lub hnub qub" los yog "daim duab peb sab". Analogy no yuav twv nrog asynchronous motors. Nws muaj ntau hom ntawm lub hwj chim transformers, uas yuav tsum tau los sib tham me ntsis tom qab.

Tab sis nyob rau hauv lub tsev pab kiag li lawm yog siv, nyob rau hauv uas ib tug winding network. Nyob rau hauv tas li ntawd, muaj tsawg kawg yog ib tug thib ob, uas yog siv rau lub hwj chim kiag li lawm. Piv txwv li, cov txheej txheem siv nyob rau hauv lub flashlamp hwj chim transformers, nyob rau hauv uas ib tug plurality ntawm ob windings. Xav Tau sawv los ntawm ib tug ntaus ntawv mus rau tau txais ob peb voltage qhov tseem ceeb: 6.3, 250 V. Ntxiv mus, nyob rau hauv ib lub neej muaj peev xwm ua tau raws li tam sim no transformers. Lawv ntsia tau rau hauv lub 'meter' thiab muab kev tswj ntawm lub ntaus ntawv.

tsim

Ib tug hauv paus transformer nyuaj faib, tab sis, yog hais tias raws li qhov nyhav, nws yog undoubtedly cov tub ntxhais (magnetic Circuit Court). Nws yog tsim los ntawm steel los xij uas tau koom ua ke ua ke thiab nruj nreem rub ua ke. Qhov no tso cai rau koj mus tau lub siab tshaj plaws tau tus ntoo khaub lig seem ntawm lub magnetic Circuit Court. Tab sis tsis tau tsuas yog lub steel yuav siv tau, feem ntau ua los ntawm ferromagnetic cores. Qhov no tshuaj, uas yog heev uas zoo sib xws nyob rau hauv cov khoom nrog cov hlau, tab sis muaj ib tug me ntsis txawv qauv. Muaj tej hom ntawm transformers, yees duab yooj yim designs yog muab nyob rau hauv tsab xov xwm.

Tus tsim yog tam sim no tsawg kawg yog ob windings. Ib tug (thawj) mov voltage yog ua. Txij li thaum lub thib ob, thib peb, N-hydrochloric, undervoltage rho nrog cov zaus thiab hauv daim ntawv ntawm zoo xws li cov tswv yim. Winding quab yuam tsim ntawm tooj liab hlau. Nws qhov txhab los rau tus ncej, uas yog nyob ib ncig ntawm lub magnetic Circuit Court. Thaum voltage yog thov rau cov thawj Circuit Court zoo nkaus li ib tug alternating magnetic teb uas induces nyob rau hauv lub thib ob winding EMF. Raws li ib tug tshwm sim, cov zis yog ib tug tej yam tej zaum txawv.

hwj chim transformers

Qhov saum toj no-hais hom yog cov uas hloov hluav taws xob mus rau hauv lub network. Nws yog tsis tsuas ntsia rau qhov transformer substations. Ntau hom ntawm lub hwj chim transformers, lawv pab tsis tau tsuas yog los txo cov voltage rau 110 kV, piv txwv li, 6 kV nyob rau hauv cov ntaub ntawv ntawm ib tug substation. Cov no muaj xws, thiab pab kiag li lawm siv nyob rau hauv lub hwj chim khoom siv ntawm tsev neeg lub xov tooj cua. Nyob rau hauv qhov tseeb, tus tsim ntawm tag nrho cov zoo sib xws, muaj ntau yam.

Txawm vuam transformers, hom uas yog ntau haiv neeg, muaj ib tug zoo qauv. Nws muaj tsuas yog me nuances, xws li lub hwj chim ntawm lub tshuab ntawm cov substations yog nruab nrog ib tug roj cua txias system, thaum lub sij hawm vuam ua hauj lwm tsis tau nws. Tab sis thaum kawg muaj cov qhov tso zis tam sim no cov kev cai. Nws yog tsim nyog rau lub vuam sib txawv ntawm cov thickness ntawm cov hlau. Zoo, tus pab kiag li siv nyob rau hauv lub neej txhua hnub, thiab nyob tag nrho deprived ntawm xws kev kho me ntsis.

Autotransformers

Autotransformer - ib qho ntawm cov hom nyob rau hauv uas lub thawj thiab windings yog kev cob cog rua ncaj qha. Qhov no ua rau nws tau mus nrhiav tau tsis tsuas yog ib tug hluav taws xob kev twb kev txuas mus rau lub ntaus ntawv, tab sis kuj electromagnetic. Feem ntau muaj peb pib-transformer ntawm cov zis, uas tso cai rau koj yuav tau txais ib tug ntau yam ntawm voltages. Ib tug txawv feature ntawm pib-transformers - siab efficiency. Tab sis muaj ib tug loj drawback - lub thawj thiab circuits tsis electrically cais los ntawm txhua lwm yam. Siv feem ntau rau cov fais fab tau txais kev pab xws kev cai transformer. Hom ntawm transformers rau lwm cov laj sib tham hauv qab no.

Xab

Rau siv nyob rau hauv AC hluav taws xob, ib tug tshwj xeeb ntawm transformers - xab. Ua tsaug rau lawv, ua cov kev txwv ntawm lub xab kiag li lawm. Tsis tas li ntawd, lawv tsis cia hluav taws xob kev twb kev txuas mus rau lub hwj chim cable rau kev ntsuas ntawm qhov tam sim no ntws los ntawm nws. Nyob rau hauv lwm yam lus, tsis muaj galvanic coupling nws yog ua tau los tswj lub tam sim no ntws nyob rau hauv lub Circuit Court. Tab sis lub ob hom ntawm kev ntsuas pab kiag li lawm yuav txawv - lub voltage thiab tam sim no transformers. Muaj ntau hom tam sim no transformers, lawv sib txawv nyob rau hauv loj thiab tau.

Tam sim no transformers cia ib tug transformation. Yog li ib tug loj tam sim no ntws nyob rau hauv lub Circuit Court yog txo mus rau ib tug muaj kev ruaj ntseg nqi. Ntxiv mus, nws muaj kev ruaj ntseg rau cov qhov tso zis tswj systems los yog kev ntsuas, kev tiv thaiv thiab tswb kiag li lawm. Primary winding - nws yog ib feem ntawm ib tug neeg xyuas pib, nyob ib ncig ntawm lub qhov winding yog ua. Nrog rau tom kawg yog muab tshem tawm tam sim no ntawm 1 ampere los yog 5. Tab sis lub voltage transformers yog tsim rau ib tug txawv hom phiaj. Lawv ua ib tug voltage nco rau kev ntsuas ntawm cov yam ntxwv. Nrog lawv pab nqa rho tawm tiv thaiv Circuit Court pab kiag li lawm los ntawm high voltage.

mem tes

Qhov no hom ntawm ntaus ntawv yog siv rau cov tshwj xeeb lub hom phiaj. Nws yog tsim nyog yuav hloov lub series ntawm pulsed Pib ntsais koj teeb. Wherein lub caij ntawm ib mem tes tej zaum yuav mus txog ob peb kaum ntawm microseconds. Thiab muaj ib tug me me feature - tus hloov xwb tus amplitude ntawm lub teeb liab, tab sis tsis nws zoo lawm. Incidentally, muaj tej hom kev tiv thaiv ntawm transformers, mem tes kuj muab circuitry, tiv thaiv tshaj voltage los yog tam sim no.

Raws li ib tug txoj cai, switching pab kiag li lawm yog siv nyob rau hauv ib tug Circuit Court nyob rau hauv uas ntws ib tug square yoj teeb liab. Feem ntau, qhov no zoo ntawm pab kiag li lawm siv nyob rau hauv qhov TV txheej txheem. Lawv hloov lub me me ntev video pulses nrog ib tug heev luag hauj lwm mus los. Thiab cov qhov tso zis koj tau ib lub teeb liab nyob rau hauv nws cov thawj daim ntawv no, tab sis, nrog nce amplitude.

xaus

Tam sim no koj paub tias dab tsi yog ib tug transformer. Hom ntawm transformers peb tau saib, thiab pom hais tias lawv muaj ib tug ob peb sib txawv, txawm lub fact tias cov qauv yog heev uas zoo sib xws. Thov nco ntsoov tias thaum ua hauj lwm nrog tej hluav taws xob khoom yog tsim nyog los soj ntsuam kev ruaj ntseg ceev faj. Ntxiv mus, rau cov AC fais kev pab cuam yuav tsum muaj ib tug kam band.
