Cov teeb meem tseem ceeb hauv kev tsim hluav taws xob transformer

Fais fab transformer yog siv los hloov AC voltage, tam sim no thiab xa AC lub zog yog cov khoom siv hluav taws xob zoo li qub, nyob rau hauv cov txheej txheem tsim yuav tsum xav txog ntau yam, tswj cov txheej txheem zoo, ncua sij hawm siv cov khoom siv.
Cov teeb meem tseem ceeb ntawm kev tsim hluav taws xob transformer yog magnetic flux thiab tam sim no ntom. Tam sim no ntawm transformer yog proportional rau lub peev xwm, thiab qhov loj ntawm qhov tam sim no ceev (xws li lub thickness ntawm cov hlau) yog xam raws li lub tshav kub generated los ntawm tus neeg xyuas pib. Rau kev sib nqus flux, qhov kev sib raug zoo ntawm electromagnetism yog u=4.44fw, qhov twg u yog qhov voltage thiab f yog qhov zaus, ntawm no nws yog 50Hz, tus nqi ruaj khov; w yog tus naj npawb ntawm lem ntawm lub kauj; Hauv φ yog qhov sib nqus flux. Txij li thaum sib nqus flux ceev B ntawm silicon steel ntawv yog txwv los ntawm cov khoom siv, feem ntau tsuas yog tsim los rau 1.4-1.8 Tesla, yog li txhawm rau nce φ, feem ntau tsuas yog thaj tsam ntawm cov hlau hlais. core tuaj yeem nce ntxiv. Cov tub ntxhais ntawm lub transformer feem ntau yog peb-theem kem hom, qhov cross-sectional cheeb tsam ntawm cov tub ntxhais hlau tuaj yeem txiav txim siab raws li cov qauv saum toj no, thiab qhov loj ntawm lub qhov rais tub ntxhais yuav tsum xav txog lub hauv paus ntsiab lus ntawm kev muab cov coil. loj dua lub peev xwm ntawm lub transformer, lub thickness ntawm cov hlau, thiab qhov loj ntawm lub qhov rais ntawm cov tub ntxhais.
Hauv kev tsim ntawm lub zog transformers, tus nqi ntawm tooj liab thiab hlau tuaj yeem sib npaug. Vim hais tias ib zaug lub peev xwm ntawm lub transformer tau txiav txim siab, qhov tam sim no tau txiav txim siab, lub thickness ntawm cov hlau yog txiav txim siab, nce tus naj npawb ntawm lem W, sib nqus flux φ tuaj yeem me dua, qhov chaw hla ntu ntawm cov tub ntxhais yuav me dua, tab sis kom cua cov kev hloov no, lub qhov rais ntawm cov tub ntxhais hlau yuav tsum loj dua; Ntawm qhov tsis sib xws, los ntawm kev txo tus lej ntawm W, qhov sib nqus flux φ yuav loj dua, thiab qhov chaw hla ntawm cov tub ntxhais hlau yuav loj dua, tab sis lub qhov rais ntawm cov tub ntxhais hlau tuaj yeem me dua.
