Kuv ntseeg hais tias txhua leej txhua tus twb paub txog transformers. "Vim li cas lub hwj chim transformer core yuav tsum tau grounded thiab tsuas yog tso cai rau grounded me ntsis." Feem ntau hais lus, feem ntau siv transformer core yog silicon steel ntawv, yog li koj paub vim li cas silicon steel ntawv yog xaiv raws li lub transformer Hlau core?
Dab tsi yog "silicon steel"? Nws muaj dab tsi?
Silicon steel yog ib hom silicon-muaj steel, thiab nws cov ntsiab lus silicon yog 0.8-4.8%. Nws muaj cov yam ntxwv ntawm siab sib nqus permeability, qis coercivity thiab loj resistivity, yog li hysteresis poob thiab eddy tam sim no poob yog me me. Feem ntau yog siv los ua cov khoom sib nqus hauv cov motors, transformers, cov khoom siv hluav taws xob thiab cov cuab yeej hluav taws xob.
Vim li cas thiaj xaiv "silicon hlau"raws li lub hauv paus ntawm lub transformer?
Silicon steel yog siv los ua cov tub ntxhais ntawm lub transformer, ua ntej ntawm tag nrho cov vim hais tias ntawm cov yam ntxwv ntawm silicon steel nws tus kheej: nws yog ib tug sib nqus cov ntaub ntawv uas muaj zog magnetic permeability. Yog li ntawd, nyob rau hauv lub tam sim no kauj, nws muaj peev xwm tsim ntau dua magnetic induction siv, uas yuav txo tau qhov luaj li cas ntawm lub transformer.
Tsis tas li ntawd, qhov hysteresis poob ntawm cov tub ntxhais transformer yog me me, uas tuaj yeem txo cov qib ntawm cov cua sov.
Nyob rau hauv qhov tseeb, lub zog poob ntawm lub transformer tsis yog tsuas yog reflected nyob rau hauv lub kuj ntawm lub coil, tab sis kuj nyob rau hauv lub hlau core. Peb feem ntau xa mus rau lub zog poob hauv cov tub ntxhais hlau ua "hlau poob". Hlau poob yog tshwm sim los ntawm ob qho laj thawj, ib qho yog "hysteresis poob" thiab lwm qhov yog "eddy tam sim no poob".
Hysteresis poob yog hais txog qhov poob uas tshwm sim los ntawm hysteresis tshwm sim hauv hlau thaum lub sij hawm magnetization txheej txheem. Qhov poob yog proportional rau thaj tsam uas nyob ib puag ncig los ntawm hysteresis voj ntawm cov khoom. Txij li thaum lub voj hysteresis ntawm silicon steel yog nqaim, hysteresis poob ntawm cov tub ntxhais siv los ua ib qho kev hloov pauv yog me me, uas tuaj yeem txo qhov ntsuas kub ntau.
