Yog lawm, ib kauj ruam -}} down transformer tuaj yeem siv los ua ib kauj ruam- dua cov kev txiav txim siab kom nco ntsoov. Ntawm no yog nws ua haujlwm li cas thiab qhov koj yuav tsum xav txog:
1. Nws ua haujlwm li cas
Transformers yog cov cuab yeej sib nciab, lub ntsiab lus lawv tuaj yeem ua haujlwm hauv ob qho tib si:
A Kauj -} down transformerTxo voltage los ntawm stepping nws nqis los ntawm thawj (ntau voltage) mus rau theem nrab (qis voltage) sab.
Yog tias koj thim rov qab cov kev sib txuas, lub winding theem nrab ua tus thawj, thiab thawj winding ua qhov thib ob, zoo nqis nce lub voltage.
2. Cov xwm txheej rau reversing siv
Rov ua dua:
Cov tswv yim thiab cov tso zis voltage qib:
Cov lus qhia voltage thov rau "Thib Ob Lub Zog" (tam sim no siv los ua thawj) yuav tsum phim cov qauv tsim qauv ntawm cov cua ntawd.
Piv txwv li, yog hais tias lub winding thib ob yog ntsuas rau 120v nyob rau hauv ib kauj ruam {}}} down voltage thaum siv raws li ib kauj ruam - Up transformer.
Cov Tso Tawm Voltage:Cov zis hluav taws xob yuav ua raws li cov thawj voltage piv. Piv txwv li:
Ib qho 240v- - 120v {}}} rau-240v kauj ruam transformer.
Zaus:
Kev khiav hauj lwm zaus yuav tsum tau nyob li qub (piv txwv li, 50 HZ lossis 60 HZ). Transformers tsim rau ib zaus tuaj yeem tsis ua rau lwm tus.
Tam sim no thiab fais fab ntsuas:
Lub hwj chim ntaus nqi (KVA) nyob tsis hloov. Yog tias tus hloov pauv tau ntsuas yog ntsuas rau 5 kva, nws tuaj yeem lis 5 kva hauv ob kauj ruam {} {{{}} down hom.
Cov winding siv rau cov hlau siab yuav muaj cov hlau diav thinner, yog li kom nws tsis dhau nws thaum nqa khoom tam sim no.
3. Kev txiav txim siab
Cov qauv tsim:
Qee cov hloov pauv tau zoo rau kauj ruam - down kev ua haujlwm, yog li lawv kev ua haujlwm hauv kauj ruam {}} Up hom yuav qis me ntsis.
Kev tswj hwm kev cai:
Kev tswj hwm cov kev cai yuav txawv thaum siv transformer nyob rov qab. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov kev siv rhiab.
Cov hloov pauv hloov (yog tias muaj):
Yog tias tus transformer muaj cov tee rau kev hloov kho voltage, lawv yuav tsis ua haujlwm raws li lub sijhawm ua haujlwm rov qab.
Rwb thaiv tsev thiab kev nyab xeeb:
Nco ntsoov tias cov rwb thaiv tsev tuaj yeem ua cov qib voltage tshiab thaum thim rov qab lub zog ntawm cov windings.
4. Thaum nws haum
Cov hloov pauv me me nrog cov qauv siv yooj yim yog cov feem ntau siv hauv kev thim rov qab vim tias lawv tsis muaj kev hloov pauv rau cov ntawv thov tshwj xeeb.
Loj lossis tshwj xeeb transformers (piv txwv li, autotransformers) tej zaum yuav muaj kev txwv thaum siv nyob rau hauv rov qab.
5. Ntsiab lus
