Kauj ruam-down transformer: hauv paus ntsiab lus ntawm cov lag luam thiab cov hom

Lub hauv paus ntsiab lus ntawm cov lag luam ntawm tej transformer yog raws li nyob rau hauv lub self-induction phenomenon. Kauj ruam-down transformer yog suab tsis txawv los ntawm povyshayuschego.Dostatochno hloov cov kev twb kev txuas txoj kev (flip caij) thiab los ntawm cov down tig tsub kom lub analog.

Tus tswj circuits ntawm transformers yog siv los kho hluav taws xob kev rho tawm, thaum lub tswv yim ntaus ntawv los theem thiab lub grounding pes tsawg, thiab cov qhov tso zis voltage zoo nkaus li tsis muaj lub earthed nruab nrab. Feem ntau nws yog siv rau lub hwj chim khoom khiav hauj lwm rau logic hais.

Muaj ib theem transformers, kauj ruam-down, ob-theem thiab peb-theem. Muaj pib-transformers thiab lub hwj chim - tag nrho cov hom yog siv ntse nyob rau hauv txawv kev qhia lub hwj chim sector.

Transformer - ib tug ntaus ntawv uas muaj ob coils nrog ib tug laminated tub ntxhais, uas yog sau los ntawm hluav taws xob hlau. Yog hais tias koj xav mus ua ib tug dog dig galvanic rho tawm, cov coils yuav tsum tau ua nrog rau cov tib lem. Yog hais tias koj xav mus ua ib kauj ruam-down transformer, tus xov tooj ntawm koj lem yog sib txawv.

Nyob rau hauv lub tswv yim ntaus ntawv yog energized (nrog rau cov winding nyob rau hauv ib tug electromotive dag zog yuam uas generates ib tug sib nqus teb). Daim teb no crosses tus coils ntawm lub thib ob kauj, qhov muaj yog nws electromotive quab yuam ntawm nws tus kheej-induction. Nyob rau hauv lem, nyob rau hauv lub thib ob kauj, dhau lawm, muaj ib tug voltage uas txawv los ntawm tus thawj rau cov nyiaj tib lub sij hawm raws li qhov sib txawv tus naj npawb ntawm lem ntawm ob windings.

Muab xam los step-down transformer uas yuav tsum tau to taub dab tsi yuav tsum tsis muaj tus ntaus ntawv. Vim lub fact tias nws tus kheej hob EMF tshwm sim vim cov lus tsa suab, lub transformer ua hauj lwm tsuas yog nyob rau AC voltage. Uas yog vim li cas nyob rau hauv lub tsev network - tsuas yog rau alternating tam sim no.

Niaj hnub no qhov no zoo yog siv advantageously li ib kauj ruam-down transformer. Vim hais tias feem ntau muaj yog ib tug yuav tsum tau hloov siab voltage kom tsawg. Lawv yog siv nyob rau hauv lub teb ntawm nroog electrification (substations thiab fais fab nroj tsuag). Chav turbines thiab tsim pas hwj chim nrog rau cov expectation ntawm kev muab lub nroog nrog ib tug tej thaj chaw ntawm lub zog, li ntawd, nws yog ib qho tseem ceeb rau siv ib kauj ruam-down transformers mus rau thawj lub voltage ntawm txhua qhov chaw twb hloov dua siab tshiab rau hauv ib tug siv tau rau kev siv.

Tab sis txos transformer yog feem ntau siv rau hauv lub tsev (rau adaptation rau cov uas tsis muaj voltage network 220). Rau lub hom phiaj no lawv yog siv nyob rau hauv electronics, fais fab mov thiab tag nrho cov tau adapters, stabilizers thiab lwm yam pab kiag li lawm.

Thaum yuav ib tug transformer yog ib qho tseem ceeb them sai sai mus rau lub efficiency, muaj peev xwm thiab xov tooj ntawm koj lem ntawm ob windings. Muaj transformers nrog ntau terminals (qhov no txhais tau tias yuav tsum tau Circuit Court tsim nyob rau hauv lub ntaus ntawv muaj xws li ob peb pab pawg ntawm cov tebchaw thiab, nyob ntawm seb qhov ntau ntawm cov tswv yim thiab tso zis qhov tseem ceeb). Qhov no universal transformers. Lawv yog cov, tiam sis, ib tug me ntsis kim kim, tab sis yog ntau npaum li cas nyob rau hauv coob.

Muaj transformers rau welding. Ntawm no siv ua counterparts. Qhov no yog ua nyob rau hauv thiaj li yuav ua tau ib lub currents yuav tsum tau rau melting hlau. Cov pab kiag li lawm yog tseem xaiv raws li tej yam tsis. Basic, ib qho yooj yim mus twv - tam sim no.
