I-12V transformer idla ngokuba sisixhobo se-AC. Kwingqiqo engqongqo yombane, i-transformer isebenza ngokutshintshana ngoku kunye nokutshintsha i-voltage ye-AC ukusuka kwelinye inqanaba ukuya kwelinye. Umzekelo, i-transformer yesiqhelo ye-12V inokunyathela i-120V AC, i-230V AC, okanye enye igalelo le-AC ukuya kutsho kwi-12V AC.
Nangona kunjalo, abantu abaninzi basebenzisa igama elithi "i-transformer" ngokungaqhelekanga ukuchaza nasiphi na isixhobo esiguqula amandla amakhulu kwimveliso ye-12V. Oku kunokudala ukubhideka. Ukuba imveliso yi-12V DC, isixhobo asiyiyo kuphela i-transformer. Ngokuqhelekileyo kunikezelo lwamandla, iadaptha, umqhubi, okanye isiguquli esibandakanya ukulungiswa kunye nommiselo. Kungenxa yoko le nto imveliso ichazwa njenge 12 v dc isiguquli kufuneka ihlolwe ngononophelo ukuqinisekisa ukuba ikhupha i-AC okanye i-DC.
Yintoni eneneni eyenzayo iTransformer?
Isiguquli sigqithisa amandla ombane phakathi kwamajiko-jiko amabini nge-electromagnetic induction. Inokuthoba i-voltage ezantsi, inyuse i-voltage phezulu, okanye ibonelele ngokwahlula phakathi kweesekethe.
Isiguquli esisisiseko sine:
- Ukujija okuphambili
- Ukujija okwesibini
- Undoqo weMagnetic
- Inkqubo ye-insulation
- Izikhululo okanye izikhokelo
- I-enclosure okanye isakhiwo sokuxhoma
I-transformer idinga igalelo le-AC kuba indawo eguqukayo yamagnetic iyafuneka ukuphembelela i-voltage kumoya wesibini. I-DC ecocekileyo ayidali efanayo ngokuqhubekayo itshintsha intsimi yamagnetic kwi-transformer eqhelekileyo.
Ngaba i-12V Imveliso ye-AC okanye ye-DC?
Impendulo ixhomekeke kwimveliso.
Imveliso ye-12VAC ye-transformer etshintshanayo yangoku. Oku kuxhaphakile kwizibane zomhlaba, iintsimbi zomnyango, izibane zamachibi, ezinye iinkqubo zolawulo, kunye neenkqubo zokukhanyisa eziphantsi kwamandla ombane.
I-12VDC ikhupha amandla ombane othe ngqo. Oku kuqhelekile kwiintambo ze-LED, iikhamera zeCCTV, iirotha, iibhodi zokulawula, izinzwa, iimotor, kunye ne-electronics.
Ukuba ileyibhile ithi "Imveliso: 12V AC," yi-AC transformer. Ukuba ithi "Imveliso: 12V DC," sisibonelelo samandla seDC okanye iadaptha, nokuba abanye abathengisi bayibiza ngokuba sisiguquli.
Yintoni i-12 V DC Transformer?
Ibinzana 12 v dc isiguquli isetyenziswa kakhulu kukhangelo lwemveliso yemihla ngemihla, kodwa ngokobuchwepheshe idla ngokubhekisa kubonelelo lwamandla lwe-12V DC. Ngaphakathi kwesixhobo, kunokubakho i-transformer okanye i-high-frequency switching circuit, kunye nezixhobo eziguqula i-AC ibe yi-DC.
Umbane oqhelekileyo we-12V DC unokubandakanya:
- Ukhuseleko lwegalelo
- I-Transformer okanye isiphaluka sokutshintsha
- Umlungisi
- Isihluzi se-capacitor

- Ukuphindaphinda
- Isiqinisekiso sokhuseleko
- Ukulinganisa kwangaphakathi okanye ngaphandle
Isimboli ye-AC inokuvela njengomgca wamaza. Isimboli ye-DC inokuvela njengomgca othe ngqo onomgca odayiweyo ngaphantsi kwayo. Unikezelo lwamandla e-DC luhlala lubonisa i-polarity, efana nendawo-positive okanye embindini-negative, kwizihlanganisi zemiphanda.
Kutheni i-AC vs. DC ibalulekile
Ukusebenzisa uhlobo lwemveliso olungalunganga lungonakalisa izixhobo okanye luthintele ekusebenzeni.
Umzekelo, i-12V AC landscape light inokusebenza kunye ne-12VAC transformer, kodwa i-12V DC strip ye-LED idla ngokufuna umbane we-12VDC. Ikhamera ye-12V DC eqhagamshelwe kwi-12V AC inokusilela. Isixhobo se-12V AC esiqhagamshelwe kwi-DC sinokungasebenzi kakuhle.
Phambi kokudibanisa nasiphi na isixhobo, qinisekisa:

Umgca vs. Ukutshintshela izixhobo zamandla ze-12V
Izixhobo zamandla ombane ophantsi zinokusebenzisa umgca okanye uyilo lokutshintsha.
Iziguquli zomgca
Isiguquli somgca sihlala sinzima kuba sisebenzisa undoqo wentsimbi osebenza kumaza omoya. Inokuthi ikhuphe i-AC ngokuthe ngqo, okanye inokuba yinxalenye yonikezelo lwamandla lwe-DC ngokulungiswa kunye nokucoca.
Ukutshintsha uBonelelo lwaMandla
Ukunikezelwa kwamandla okutshintsha ngokuqhelekileyo kuncinci kwaye kulula. Iguqula umbane ngamaxesha aphezulu kwaye inokubonelela ngemveliso elawulwayo ye-DC ngokufanelekileyo. Iiadaptha ezininzi zanamhlanje ze-12VDC zisebenzisa iteknoloji yokutshintsha.
Zombini ezi ntlobo zinokuba luncedo, kodwa ukhetho oluchanekileyo luxhomekeke kumthwalo, uvakalelo lwengxolo, imfuneko yokusebenza kakuhle, kunye neemeko zofakelo.
Ungasikhetha njani isixhobo esiLungileyo se-12V
Xa ukhetha i-12V isiguquli okanye unikezelo lwamandla, qwalasela:
- Ngaba isixhobo sifuna i-AC okanye i-DC?
- Loluphi unyamezelo lombane oluvumelekileyo?
- Zingaphi iiampe ezifunekayo?
- Ngawaphi amanzi ewonke afunekayo?
- Ngaba umthwalo uyaqhubeka okanye uphakathi?
- Ingaba isixhobo singaphakathi okanye singaphandle?
- Ngaba ifuna ukukhuselwa kwamanzi?
- Ngaba i-DC polarity ibalulekile?
- Ngaba ukhuseleko oludlulayo luyafuneka?
- Ngaba ukufakela kufuna ukubekwa wedwa?
- Ngaba imigaqo yombane yendawo iyasebenza?
Ukukhanya kwe-LED kunye ne-electronics, khetha umbane olawulwayo we-12VDC. Ukukhanya kwe-AC okanye iinkqubo zokulawula, khetha i-transformer elinganiswe ngokufanelekileyo ye-12VAC.
Ubungakanani be-12V Transformer okanye iSibonelelo saMandla
Umthamo wamandla udla ngokubalwa kunye ne-watts okanye i-volt-amps.
Ngemithwalo ye-DC:
Watts = iivolthi x iiamps
Umzekelo, umzobo wesixhobo se-12V DC i-5 amps idinga malunga nama-watts angama-60. Kuqhelekile ukuba bubulumko ukukhetha unikezelo lwamandla olunomthamo owongezelelweyo kunokuba luqhube ngokuqhubekayo ngokomlinganiselo walo ophezulu.
Kwimithwalo ye-AC transformer, ukulinganisa kwe-VA kusetyenziswa ngokuqhelekileyo. I-transformer ye-12VAC elinganiswe kwi-100VA inokubonelela malunga ne-8.3 amps kwi-12V phantsi kweemeko ezilinganisiweyo.
Iingqwalasela zoKhuseleko
I-voltage ephantsi ayithethi ukuba akukho mngcipheko. Inkqubo ye-12V isenokuthi ifudumale ngokugqithisileyo iingcingo, yonakalise izixhobo, ibangele iintlantsi, okanye idale iingozi zomlilo ukuba ilayishwe kakhulu okanye ifakwe iintambo ngendlela engafanelekanga. Icala eliphambili le-transformer okanye unikezelo lwamandla lunokuthi luqhagamshele kumbane oyingozi.
Ukufakela kufuneka kulandele imiyalelo yemveliso kunye neemfuno zombane ezifanelekileyo. Iinkqubo zangaphandle kufuneka zisebenzise iindawo ezivaliweyo ezifanelekileyo kwimozulu kunye neendlela zocingo.
Ukuqukumbela
I-12V yokwenyani ye-transformer idla ngokukhupha i-12V AC. Ukuba isixhobo sikhupha i-12V DC, idla ngokuba ngumbane, iadaptha, umqhubi, okanye isiguquli, nokuba siqhele ukubizwa ngokuba sisiguquli.
Into ephambili kukujonga ileyibhile kwaye utshatise imveliso kwisixhobo. A 12 v dc isiguquli ukukhangela kudla ngokukhomba umbane we-12V DC, ngelixa i-transformer ye-12VAC isetyenziselwa iinkqubo ze-AC low-voltage. Ukukhetha i-AC okanye imveliso ye-DC echanekileyo inceda ukukhusela izixhobo, ukuphucula ukuthembeka, kunye nokuxhasa ukufakela okukhuselekileyo.
Ngolwazi lwemveliso ye-transformer kunye ne-low-voltage, tyelela JS Ningyi.
