Qhov sib txawv ntawm kev hloov fais fab mov thiab transformer
Ua ntej, qhov hloov hluav taws xob yog DC DC, thiab qhov hloov pauv yog AC AC; Qhov thib ob, hloov cov khoom siv hluav taws xob ua haujlwm ntawm lub zog siab (feem ntau nyob rau hauv kaum ntawm kilohertz ntau), thiab cov transformers muaj ob qho tib si siab thiab tsawg zaus. Cov pulse transformers siv nyob rau hauv cov khoom siv hluav taws xob hloov hluav taws xob yog cov khoom siv hluav taws xob ntau zaus, nrog cov hlau cores xws li ferrite, uas yog qhov me me thiab kev ua haujlwm siab (qhov ntau zaus, qhov ua tau zoo dua). Thaum nws los txog rau transformers, thawj yam uas los rau hauv lub siab yog lub hwj chim zaus transformer, uas ua hauj lwm ntawm ib zaus ntawm 50 hertz thiab suav hais tias yog ib tug low-frequency transformer, cov tub ntxhais hlau yuav tsum tau stacked nrog silicon steel nplooj ntawv ua los ntawm mos magnetic. cov ntaub ntawv (kom tiv thaiv eddy tam sim no los ntawm tsim Joule tshav kub); Ntxiv dua thiab, cov haujlwm ua haujlwm ntawm ob qhov tsis zoo ib yam. Cov khoom siv hluav taws xob hloov pauv suav nrog lub tshuab hluav taws xob mem tes, nrog rau cov khoom siv hluav taws xob sab sauv thiab sab qis. Tsis hais txog ntawm qhov ntau zaus ntawm lub transformer, nws tsuas yog ib qho kev hloov pauv tsis muaj kev ua haujlwm rectifier;
Yog hais tias peb tham txog ib rooj plaub, cia peb tham txog lub hwj chim Circuit Court ntawm lub TV! Lub hwj chim mov ib feem ntawm ib lub TV xim yog ib tug raug hloov fais fab mov; Lub hwj chim mov Circuit Court ntawm dub thiab dawb TV yav dhau los yog tsim los ntawm lub hwj chim zaus transformer thiab ib tug rectification, filtering, thiab voltage stabilizing Circuit Court. Cov xim TV fais fab mov ncaj qha rectifies 220V AC zog rau ib ncig ntawm 300V DC lub zog, uas yog txiav mus rau hauv high-frequency pulses los ntawm ib tug switching transistor. Tom qab ntawd nws raug txo los ntawm cov mem tes sib nqus core transformer, thiab tom qab ntawd kho thiab lim kom tso zis tsawg-voltage DC (tag nrho cov txheej txheem kuj daws qhov teeb meem voltage stabilization); Cov txiaj ntsig ntawm cov txheej txheem no tuaj yeem raug hu ua lub zog hloov hluav taws xob. Lub hwj chim zaus transformer nyob rau hauv lub dub thiab dawb TV, Tij Laug, sawv cev rau qhov koj hu ua transformer, uas tsis suav nrog ib tug rectification thiab filtering circuits. Yog li cov haujlwm ua haujlwm ntawm ob qhov tsis zoo ib yam.
Lub hwj chim zaus transformer puas tuaj yeem txuas nrog lub voj voog ntawm lub zog hloov hluav taws xob?
Tsis yog, lub zog zaus transformer siv cov tub ntxhais hlau, uas yog ua los ntawm cov khoom siv hlau thiab inherently conductive. Nws tsuas yog tsim nyog siv rau hauv lub zog zaus transformers. Thaum siv nyob rau hauv high-frequency switching fais fab mov, eddy tam sim no poob yuav loj heev thiab tsis ua hauj lwm zoo. Lub zog hloov hluav taws xob siv lub tshuab hluav taws xob sib nqus, uas yog cov khoom siv hluav taws xob tab sis tsis muaj hluav taws xob, thiab yuav tsis muaj qhov poob tam sim no. Ntxiv mus, cov khoom siv hluav taws xob hloov pauv tau nruj heev rau kev tsim cov khoom siv hluav taws xob, thiab lawv tsis tuaj yeem ua haujlwm ib txwm los ntawm kev sib txuas ntawm lub transformer. Koj qhov xwm txheej xav tau tam sim no ntau, thiab lub khoos phis tawj hluav taws xob tsis tuaj yeem muab cov tam sim no ntau.
