Dab tsi yog Step Down Fais Fab Transformer?

Cia wb ua tiag ib pliag. Tej zaum koj tau ntsaws koj lub laptop charger rau hauv phab ntsa ib lab zaug yam tsis xav txog nws.

Phab ntsa muab rau koj 120V lossis 220V-nyob ntawm seb koj nyob qhov twg. Qhov ntawd yog kua txiv ntau. Tab sis koj lub laptop? Nws xav tau 5V txog 20V, feem ntau DC.

Yog li ntawm no yog qhov txaus ntshai: yog tias phab ntsa hluav taws xob tau ncaj qha mus rau hauv koj lub computer ... boom. Fried motherboard. Melted yas. Tej zaum txawm yog hluav taws me me.

Yog li vim li cas ho tsis tshwm sim?

Ua tsaug raudown zog transformer. Tiag tiag. Nws yog ib qho ntawm cov tho txawv - saib tej yam uas ua tau ib yam dab tsi amazing.

Hauv lus Askiv yooj yim, nws yog ib qho cuab yeej siv hluav taws xob siab thiab txo qis nws - tsis muaj qhov txav, tsis muaj khawv koob, tsuas yog zoo qub physics.

Koj pub nws qhov hluav taws xob siab ntawm ib sab, thiab tawm los qis dua, muaj kev nyab xeeb dua rau lwm qhov. Qhov ntawd yog nws.

Lub npe hais tias nws tag nrho: nws nce voltagenqes.

Lub transformer tsuas muaj peb qhov tseem ceeb. Tsis kidding:

A hlau core(feem ntau yog hlau, stacked nyob rau hauv nyias txheej).

A thawj winding- uas yog lub input coil.

A theem nrab winding- qhov tso zis coil.

Nov yog qhov ua kom yuam kev: ob lub coils yeej tsis kov. Tiag tiag. Lub zog dhia hla cov tub ntxhais siv lub tshuab magnetic. Zoo li qus thaum koj xav txog nws.

Txoj cai hu uatig ratio. Lub npe zoo nkauj, lub tswv yim yooj yim.

Hais tias thawj muaj 100 loops ntawm hlau.

Thiab qhov thib ob muaj 10 loops.

Qhov ntawd yog 10-rau-1 piv.

Muab 120V rau hauv? Koj yuav tau txais kwv yees li 12V tawm.

Thiab vim qhov thib ob muajtsawg duatig, lub zog poob. Tias yog vim li cas peb hu nws kauj ruam - nqis.

Ib qho ntxiv: transformers tsuas yog ua haujlwm nrogACzog. DC yuav tsis ua li ntawd - lub magnetic teb yuav cia li zaum ntawd tsis ua dab tsi. Yog li tsis txhob sim.

1. Tsiv Lub Hwj Chim Ntev Ntev (Tsis Muaj Txhua Yam)

Cov nroj tsuag fais fab feem ntau nyob deb ntawm cov nroog. Yog tias peb xa hluav taws xob ntawm 120V tag nrho txoj kev ntawd, feem ntau ntawm nws yuav tig mus ua cua sov ua ntej nws tau txais rau koj. Cov khib nyiab loj heev.

Yog li ntawm no yog qhov peb ua xwb:

Ua ntej, ance lub zog transformerjacks qhov voltage txoj kev nce (xws li pua pua txhiab tus volts) rau kev mus ncig ntev.

Tom qab ntawd, nyob ze koj lub zej zog, adown zog transformercoj nws rov qab los.

Thiab thaum kawg, lub thawv me me grey ntawm tus ncej? Yep-lwm nqes hluav taws xob hloov pauv, coj nws mus rau 120V lossis 240V rau koj lub tsev.

Yog tsis muaj transformers, daim phiaj tsuas yog yuav tsis ua haujlwm. Yooj yim li ntawd.

2. Cia koj ciaj sia (Tsis muaj tso dag)

High voltage tuaj yeem tua koj. Qhov ntawd tsis yog qhov txaus ntshai - nws tsuas yog qhov tseeb.

Tab sis thaum koj kov USB kawg ntawm koj lub xov tooj charger, koj nyob ib leeg tag nrho ntawm qhov tuag taus 230V hauv koj phab ntsa. Vim li cas? Vim lub transformer zaum hauv nruab nrab. Tsis muaj kev ncaj qha hluav taws xob los ntawm phab ntsa mus rau koj txhais tes.

Qhov ntawd hu uagalvanic cais. Lub sij hawm zoo nkauj, tab sis txhua yam nws txhais tau tias yog "koj yuav tsis tau txais hluav taws xob."

Zoo nkauj heev, txoj cai?

3. Cov khoom sib txawv xav tau cov kua txiv hmab txiv ntoo sib txawv

Tsis yog txhua yam khiav ntawm tib qhov voltage. Xav txog nws:

Koj lub tshuab nqus tsev vacuum? Xav tau 120V los tig lub cev muaj zog.

Koj lub tswb nrov? Ntau tshaj li 16V. (Yog vim li cas nws thiaj li muaj qhov me me transformer nyob rau hauv koj lub qab daus los yog txee dai khaub ncaws.)

LED teeb strips? Feem ntau 12V.

Ib kauj ruam nqis zog transformer ua kom txhua yam khoom tau txais raws nraim qhov nws xav tau.

Nov yog daim ntawv qhia ceev ceev:

Koj tau taug kev dhau ntau pua ntawm cov no yam tsis tau pom dua. Tam sim no koj paub.

kVA ntsuas:Xav txog qhov no raws li qhov hloov pauv "qhov loj" lossis ntau npaum li cas nws tuaj yeem ua haujlwm ua ntej overheating. Yog tias koj qhov load yog 5,000 watts, yuav ib yam khoom ntsuas siab dua -zoo li 6kVA. Ib txwm tso qhov tsis tuaj. Cia siab rau kuv ntawm qhov no.

Kev rho tawm transformer:Qhov no yog qhov nthuav. Nws tsis hloov voltage kiag li. Tib yam hauv, tib yam tawm. Tab sis nws ntxuav lub zog qias neeg thiab tshem tawm cov suab nrov hluav taws xob. Cov khoom siv suab zoo nkauj thiab cov khoom siv kho mob nyiam cov no.

Kev ua tau zoo:Transformers zoo txaus ntshai-95% txog 99%. Uas poob zog? Nws hloov mus ua cua sov. Yog vim li cas transformers thiaj li sov txawm tias tsis muaj dab tsi ntsaws rau hauv.

Feem ntau, transformers muaj kev nyab xeeb thiab tho txawv. Tab sis tib neeg ua yuam kev.

1. Tsis txhob thim rov qab ib kauj ruam ntawm lub hwj chim transformer.

Tiag tiag. Tsis txhob.

Yog tias koj ntsaws 120V rau hauvtso zissab (the low-voltage side), thenkagsab yuav sim muab rau koj vwm -siab voltage-zoo li ntau txhiab volts. Qhov ntawd yuav rhuav tshem lub transformer thiab tejzaum nws tua koj.

Cia li tsis txhob.

2. Lawv kub. Deal nrog nws.

Transformers ua kom sov. Tsis txhob faus ib qho rau hauv rwb thaiv tsev, tsis txhob npog nws nrog ib daim pam, thiab tsis txhob muab tso rau hauv lub thawv kaw uas tsis muaj cua nkag. Muab chav ua pa rau nws.

3. Ib txwm siv lub fuse lossis breaker nyob rau sab nkag.

Qhov ntawd tsuas yog kev nyab xeeb yooj yim xwb. Yog hais tias ib yam dab tsi luv nyob rau hauv, lub fuse pops es tsis txhob ntawm lub transformer ntes hluav taws.

Saib, kauj ruam down power transformer tsis glamorous. Nws tsis muaj Bluetooth. Koj tsis tuaj yeem tshaj tawm txog nws ntawm Instagram. Tab sis ncaj ncees? Nws yog ib qho tseem ceeb tshaj plaws inventions ntawm 150 xyoo dhau los.

Yog tsis muaj nws, peb tsis tuaj yeem txav zog hla lub nroog. Yog tsis muaj nws, koj lub xov tooj thiab lub laptop yuav tawg qhov thib ob uas koj ntsaws rau hauv.

Yog li tom ntej no koj hnov ​​​​cov suab nrov me ntsis ntawm koj lub charger -los yog nias thaum lub tshuab hluav taws xob ncaws tawm hauv - muab kev hwm rau nws. Nws ntsiag to taming txaus hluav taws xob tua koj, yog li koj tuaj yeem tshawb xyuas koj tus email.

Hu rau tam sim no
