Kauj ruam-down transformer 36 mus rau 220 volts

Lub transformer 220 yog 36 volts yog zoo tagnrho rau cov powering lub teeb pom kev zoo Circuit Court nyob rau hauv da, saunas, chav dej, qab tsev. Kev Nyab Xeeb yuav tsum kom tej yam txwv rau kev siv ntawm alternating voltage nqi ntawm 220 volts uas muaj av noo. Yog li ntawd, ib qho zoo tagnrho txoj kev tawm ntawm no qhov teeb meem yog siv ib AC voltage ntawm 12, 24 los yog 36 volts. Yog hais tias ib tug neeg los mus rau hauv kev sib cuag nrog lub hluav taws xob network, nws yuav xav tsuas yog ib tug me ntsis poob siab. Nws yuav tsis ua kom muaj mob mus rau tib neeg lub cev.

Tus tsim ntawm lub transformer

Zoo li lwm yam kev kauj ruam-down transformer 220 yog 36 volts muaj peb lub ntsiab Cheebtsam:

1. Lub hom winding.
2. Cov theem nrab winding.
3. Lub magnetic tub ntxhais.

Thiab thawj thiab windings yog ua los ntawm ib tug tej yam muaj pes tsawg tus lem ntawm tooj liab hlau. Feem ntau nws yog siv tooj liab hlau nyob rau hauv cov kua roj vanish rho tawm, vim nws nws tus yam ntxwv npaum li cas zoo dua txhuas. Yog hais tias koj siv txhuas, nws yuav yuav tsum tau ob peb lub sij hawm ntau, uas ho tsub kom qhov luaj li cas ntawm cov transformer. Txawm li cas los, txhuas varnished Cooper hlau siv yav tas los nyob rau hauv voltage regulators. Tus quab tej zaum yuav nqa tawm los ntawm transformer hlau thiab ntawm ib tug ferromagnet. Qhov no cov ntaub ntawv uas, uas yog tshuam zoo dua ib yam ntawm cov hlau.

Lub hwj chim thiab lub transformation coefficient

Koj muaj peev xwm txawm visually kwv yees lub hwj chim ntawm tej transformer - tus loj dua cov loj, lub siab dua nws yog. Tab sis kom meej xam lub hwj chim koj yuav tau siv ib tug tshwj xeeb mis. Qhov yooj yim txoj kev ntawm kev xam lub hwj chim transformer - ib tug npaug ntawm ob winding voltage rau qhov tam sim no lub dag lub zog nyob rau hauv nws. Tau qhov tiag tus nqi ntawm lub hwj chim ntawm lub xeem transformer. Mus ua hauj lwm nyob rau hauv cov creation thiab tsim ntawm xws li ib tug ntaus ntawv, koj yuav tsum tau paub lwm lub ntsiab parameter characterizing lub transformer.

Qhov no yog tsis muaj dab tsi lwm tus tshaj qhov piv ntawm transformation. Nws nruab nrab yog cov piv ntawm tus xov tooj ntawm ob lem mus rau cov thawj. Cov nqi yuav tsum tau los mus faib I2 / I1, thiab U2 / U1 voltage. Nyob rau hauv ib yam ntawm cov peb tus neeg mob, koj yuav tau txais tib yam nqi. Nws yog tej zaum koj yuav xav tau rau nws tus kheej-xam lub caij nyoog tooj lem rau lub thawj thiab windings.

muab xam los ntawm cov transformer

Yog hais tias nws yog tsim nyog los tsim ib tug transformer 220 rau 36 volts (1000 watts), nws yog ntshaw kom siv cov mis rau xam hwj chim nyob rau hauv ib tug thib ob winding. Nws twb hais saum toj no, lub hwj chim yog sib npaug zos rau cov khoom ntawm lub tam sim no rau voltage. Yog li muaj ob tug tsis uas yog notoriously paub - P2 yog ncaj qha hwj chim (1000 W) thiab cov voltage U2 nyob rau hauv lub thib ob Circuit Court (36). Los ntawm cov mis no nws yog tam sim no tsim nyog los mus laij lub tam sim no uas ntws los ntawm cov thawj Circuit Court.

Ib tug ntawm cov tseem ceeb tsis - yog lub efficiency uas nyob rau hauv transformers tsis pub tshaj 0.8. Nws qhia tau hais tias tus nqi ntawm lub hwj chim noj ncaj qha los ntawm lub network, nkag mus rau hauv lub load kev cob cog rua rau lub thib ob kauj (nyob rau hauv cov ntaub ntawv no tau tsuas yog 80%). Qhov txawv nyob rau hauv lub hwj chim yog rau cua sov rau cov tub ntxhais thiab windings. Nws poob, thiab irretrievably. Lub hwj chim uas yog noj los ntawm lub AC, yog tus piv ntawm P2 rau efficiency.

Lub magnetic tub ntxhais ntawm lub transformer

Tag nrho cov hwj chim kis los ntawm tus thawj rau lub qhov winding los ntawm lub magnetic flux uas yog generated nyob rau hauv lub nqus cov tub ntxhais (ntxhais). Nws nyob rau ntawm lub hwj chim P1 ntawm cov tub ntxhais ntoo khaub lig seem cheeb tsam S. Nyob rau hauv Feem ntau, rau cov tub ntxhais siv ib tug txheej ntawm daim hlau nyob rau hauv daim ntawv ntawm cov tsab ntawv "W". Nyob rau hauv no tus ntoo khaub lig-sectional cheeb tsam sib npaug zos rau cov khoom ntawm lub square hauv paus ntawm P1 los ntawm ib yam ntawm 1.2. Paub cov nqi ntawm cov cheeb tsam, nws yog ua tau los mus txiav txim tus naj npawb ntawm lem W 1 V. Yuav kom ua li no, 50 muab faib los ntawm lub cheeb tsam.

Voltage nyob rau hauv lub thawj thiab windings paub - yog 220 thiab 36 volts. Cov nab npawb ntawm cov lem rau txhua lub windings yog txiav txim los ntawm txawj cov voltage rau W. Nyob rau hauv cov kev tshwm sim hais tias cov zauv qhov tseem ceeb yog tau, lawv yuav tsum tau npawv mus rau lub tom ntej no dua. Koj kuj yuav tsum xav txog dab tsi tshwm sim thaum koj txuas ob Circuit Court load voltage nco. Vim li no, nws yog ntshaw kom nce tus naj npawb ntawm lem los ntawm kwv yees li 10% ntawm theoretical.

winding nyob ntawm tej

Thiab tam sim no peb yuav tsum tau mus ua ib tug muab xam los ntawm cov tam sim no nyob rau hauv lub thawj thiab windings. Tam sim no yog sib npaug zos rau cov piv ntawm lub hwj chim voltage. Yog hais tias lub transformer 220 yog ua nyob rau ntawm lub 36 volts (500 watts), ces tam sim no yuav ntws nyob rau hauv lub thib ob Circuit Court, uas yog tus piv 500/36 = 13,89 A. Cov zis nyob rau hauv cov thawj Circuit Court yuav ua ncaj rau 625 W, thiab cov amperage - 17,36 A.

Tom ntej no, xam cov tam sim no ceev. Qhov no parameter qhia txog dab tsi lub amperage ntog rau txhua square millimeter cheeb tsam ntawm cov hlau seem. Feem ntau, tam sim no transformers tau txais ib tug ntom ntawm 2 A / square. hli. Cov kab uas hla ntawm lub hlau yuav tsum tau rau winding yuav txiav txim los ntawm ib tug yooj yim mis: Efficiency tau khoo los ntawm cov square hauv paus ntawm qhov tam sim no. Thiaj li, nws yog tsim nyog los siv ib hlau uas nws txoj kab uas hla yog sib npaug zos rau cov khoom ntawm 0.8 rau 3,73 nyob rau hauv lub thib ob Circuit Court - yog 2.9 hli (npawv mus rau 3 hli). Lub hom winding ntawm qhov yuav tsum tau siv ib tug hlau uas nws txoj kab uas hla yog 3,33 hli. Nyob rau hauv cov ntaub ntawv uas, yog tias koj tsis hlau mus rau lub yam kab uas hla, nws yog tej zaum yuav siv ib tug yooj yim ua kom yuam kev. Yuav kom poob ib txhij ob peb nyob ntawm tej kev cob cog rua rau hauv parallel. Lub sum ntawm tus ntoo khaub lig seem yuav tsum tsis muaj tsawg tshaj li uas uas tau npaj los ntawm koj. Hlau sib npaug zos rau cov piv ntawm efficiency mus rau lub square ntawm txoj kab uas hla.

xaus

Paub cov yooj yim qauv, koj yuav manually ua ib tug txhim khu kev qha transformer uas yuav ua hauj lwm nyob rau hauv lub zoo tagnrho hom. Tab sis peb yuav tsum tau paub yuav ua li cas coj mus cuag cov transformer 220 mus rau 36 volts. Qhov no yog tsis muaj dab tsi nyuab, nws yog txaus mus cuag cov thawj winding mus rau lub AC mains ntawm 220 V, thiab cov theem nrab - mus thauj khoom, teeb pom kev zoo, piv txwv li. Thaum tus thawj pib sim mus txuas rau transformer rau lub siab tshaj plaws load lub hwj chim, los mus txiav txim seb puas muaj overheating ntawm cov tub ntxhais thiab windings.
