Vim li cas tsis tuaj yeem hloov hluav taws xob hloov zaus?
Fais fab transformers tuaj yeem hloov pauv, thiab qhov kev txhim kho hluav taws xob zoo dua rau kev tsim khoom thiab lub neej xav tau. Ntau tus neeg yuav xav paub seb lub tshuab hluav taws xob puas tuaj yeem hloov pauv ntau zaus, uas yog hais, zaus ntawm transformers. Lo lus teb tsis yog. Wb mus to taub ua ke. Cia peb saib vim li cas qhov zaus hloov tsis tau.
Transformers yog tsim los ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction. Lub hauv paus ntawm electromagnetic induction yog qhov hloov pauv ntawm cov hlau nplaum sib nqus hauv lub voj kaw kom tsim hluav taws xob. Qhov sib nqus flux kis tau nyob rau hauv lub kaw hlau tub ntxhais, yog li qhov kev hloov pauv yog tib yam, uas yog, qhov zaus ntawm ob sab yog tib yam. Txawm li cas los xij, vim hais tias tus naj npawb ntawm cov coils ntawm ob sab sib txawv, qhov hloov hluav taws xob hloov pauv, uas yog, qhov hloov pauv voltage tau paub.
Cov qauv ntawm cov zaus hloov pauv feem ntau yog thawj zaug hloov pauv tam sim no rau hauv qhov tam sim no ncaj qha los ntawm kev tswj tsis tau rectifier Circuit Court thiab ntxiv rau lub capacitor, thiab tom qab ntawd paub txog qhov hloov pauv zaus los ntawm kev hloov ntawm lub zog hluav taws xob. Yog li ntawd, lub inverter yog lub zog hloov hluav taws xob, tab sis cov zis hluav taws xob waveform tsis yog tus qauv sine yoj, tab sis PWM nthwv dej, tab sis qhov sib thooj tam sim no waveform yog ze rau sine yoj. Tam sim no, SVPWM thev naus laus zis feem ntau yog siv los tswj cov khoom siv hluav taws xob hluav taws xob. Ntawm chav kawm, lub inverter kuj tseem yuav hloov qhov voltage thaum lub zaus hloov, lub hom phiaj yog kom cov sib nqus flux ntawm lub cev muaj zog ntawm tus nqi tas li. Qhov kev hloov pauv ib txwm yog tias thaum qhov zaus qis dua 50HZ, qhov hluav taws xob txo qis thiab siv lub zog torque tas li; Thaum qhov zaus siab dua 50HZ, qhov voltage yog qhov ntsuas hluav taws xob ntawm lub cev muaj zog thiab tsis nce nrog nws, thiab kev siv hluav taws xob tas li.
Los ntawm kev nkag siab txog lub zog transformer thiab zaus converter, nws pom tias lawv cov qauv sib txawv kiag li. Lub transformer yog ib tug kaw hlau core, thiab tus nqi ntawm kev hloov pauv yog tib yam, uas tsis tuaj yeem ua tiav lub hom phiaj ntawm kev hloov pauv zaus.
