Transformer xaiv specifications xa mus rau ib tug series ntawm cov qauv kev thiab kev khiav hauj lwm cov txheej txheem uas yuav tsum tau ua raws li thaum xaiv ib tug transformer kom paub tseeb tias nws ua tau raws li cov kev xav tau ntawm cov kev siv tiag tiag. Transformer xaiv yuav tsum xav txog ntau yam, nrog rau qib voltage, muaj peev xwm, load yam ntxwv, ib puag ncig, kev ua tau zoo, thiab tus nqi. Hauv qab no yog cov ntsiab lus tseem ceeb rau kev xaiv transformer:
Qib Voltage: Cov tswv yim thiab cov zis voltages ntawm lub transformer yuav tsum sib phim rau theem voltage ntawm daim phiaj fais fab lossis cov khoom siv. Piv txwv li, kev lag luam fais fab feem ntau xav tau 10kV / 0.4kV transformer, thaum siab -voltage kis tau tus mob yuav xav tau 110kV lossis 220kV transformer.
Kev xaiv Peev Xwm: Lub peev xwm ntawm lub tshuab hluav taws xob yuav tsum tau txiav txim siab raws li qhov xav tau ntawm qhov siab tshaj plaws load, thaum tseem xav txog cov kev xav tau nthuav dav yav tom ntej. Feem ntau, lub peev xwm ntsuas ntawm lub transformer yuav tsum me ntsis loj dua qhov siab tshaj plaws load kom tsis txhob overloading.
Load yam ntxwv: Ntau hom loads (xws li resistive, inductive, lossis capacitive loads) muaj qhov sib txawv ntawm kev ua haujlwm rau cov transformers. Piv txwv li, inductive loads tuaj yeem ua rau txo qis zog, yuav tsum tau xaiv lub transformer nrog luv luv dua -circuit impedance.
Environmental Conditions: Qhov chaw ua haujlwm ntawm lub tshuab hloov pauv (xws li qhov kub thiab txias, av noo, thiab qhov siab) cuam tshuam rau nws txoj kev ua haujlwm thiab lub neej ntev. Nyob rau hauv siab - av av los yog siab - thaj chaw siab, tshwj xeeb tsim transformers, xws li qhuav- hom lossis siab - qhov siab hloov pauv, tej zaum yuav xav tau.
Yuav tsum muaj kev ua tau zoo: High- transformers ua tau zoo tuaj yeem txo cov nqi khiav lag luam, tab sis kev nqis peev thawj zaug yog siab dua. Raws li lub sijhawm ua haujlwm tiag tiag thiab cov nqi hluav taws xob, cov khoom siv hluav taws xob sib txawv tuaj yeem xaiv tau, xws li Qib 1 lossis Qib 2 kev ua haujlwm zoo.
Txoj kev ua kom txias: Transformer txias txoj kev muaj xws li roj-immersed, qhuav- hom, thiab roj- insulated. Roj-immersed transformers yog haum rau loj- muaj peev xwm thiab siab- cov ntawv siv hluav taws xob, thaum qhuav- hom transformers yog qhov tsim nyog rau cov chaw uas muaj kev tiv thaiv hluav taws kub.
Luv -Circuit Peev Xwm: Lub transformer yuav tsum muaj luv luv -circuit withstand peev los tiv nrog luv luv-circuit faults nyob rau hauv daim phiaj fais fab. Luv-circuit impedance yog ib qho tseem ceeb parameter rau kev ntsuas lub transformer luv-circuit muaj peev xwm.
Rwb thaiv tsev chav kawm: Cov chav kawm rwb thaiv tsev ntawm lub tshuab hluav taws xob txiav txim siab nws cov hluav taws xob tiv taus thiab kev pab cuam lub neej. Cov chav kawm rwb thaiv tsev feem ntau suav nrog Class A, Class B, Class F, thiab Class H, nrog Class H rwb thaiv tsev muaj qhov kub siab tshaj plaws.
