Hauv lub zog hluav taws xob, tuslub pauv hloovplays ib lub luag haujlwm tseem ceeb. Nws tuaj yeem paub cov kev hloov hluav taws xob, kis tau thiab faib khoom hluav taws xob ntawm cov hluav taws xob sib txawv. Nyob rau hauv cov txheej txheem ntawm voltage/emulation ntawm cov hloov pauv, muaj qhov tseem ceeb - "siab rau cov profile siab, tsawg rau tsawg profile". Yog li, vim li cas thiaj li yuav hloov pauv voltage kev cai ua raws li cov ntsiab cai no? Cov ntsiab cai tshawb fawb thiab cov kev txiav txim siab zoo tom qab no yog dab tsi? Cia peb delve mus rau hauv lub ntiaj teb zoo ntawm kev hloov hluav taws xob voltage.
Ua ntej, cov txheej txheem yooj yim thiab kev ua haujlwm ntawm kev hloov pauv
Lub transformer yog cov khoom siv hluav taws xob uas siv cov hauv paus ntsiab lus ntawm indcroom intrali induction kom hloov AC voltage. Nws yog mas muaj kev sib haum ntawm cov hlau core thiab winding. Thaum AC tam sim no hla dhau ntawm thawj lub tshuab winding ntawm cov transformer, nws tsim ib qho kev sib yuav sib nqus hauv cov tub ntxhais. Qhov no hloov sib nqus no tsim lub zog hluav taws xob hauv lub tshuab hluav taws xob hauv theem nrab, yog li ua tiav qhov hloov hluav taws xob.
Txoj haujlwm ntawm tus transformer tsuas yog muaj cov hauv qab no:
Voltage hloov dua siab tshiab: transformers tuaj yeem hloov cov hluav taws xob ntau rau cov hluav taws xob tsawg, kom tau raws li cov khoom siv sib txawv.
Kev hloov dua tshiab tam sim no: Raws li lub zog txuag lub ntsiab cai ntawm tus hloov pauv, voltage thiab tam sim no yog qhov sib luag. Yog li ntawd, thaum lub transformer hloov lub voltage, nws kuj tseem hloov qhov loj ntawm cov tam sim no raws li.
Impedance hloov dua siab tshiab: transformer tuaj yeem hloov kho cov tswv yim thiab cov zis impedance los ntawm kev hloov pauv sib npaug ntawm cua. Qhov no yog qhov tseem ceeb rau cov khoom siv hluav taws xob nrog cov kev cuam tshuam sib txawv.
Kev Rho Tawm: Lub Koom Haum Me Nyuam thiab Thib Ob ntawm cov transformer yog txuas los ntawm hluav taws xob induction, thiab tsis muaj qhov hluav taws xob ncaj qha. Qhov no tso cai rau tus hloov pauv mus ua si lub luag haujlwm hauv kev cais tawm ntawm cov voltage sib txawv, txhim kho kev nyab xeeb ntawm lub zog hluav taws xob.
