Qhov laj thawj yog vim li cas lub hloov hom fais fab muab khoom siv tau tam sim no
Ntawm ntau yam siv fais fab siv fais fab yav dhau los thiab tam sim no, hloov hom fais fab khoom muaj zog heev thiab feem ntau tuaj yeem ua tau raws li cov qauv tsim. Lub zog hluav taws xob no yog kev lag luam heev, tab sis kuj muaj qee qhov teeb meem hauv kev tsim qauv. Qhov no yog vim li cas ntau yam hloov lub zog fais fab (tshwj xeeb tshaj yog high fais fab hloov fais fab khoom) muaj qhov xam pib qhov tseeb: lawv yuav tsum tau kos ib lub sijhawm tam sim no ntawm lub sijhawm muaj hwj chim. Qhov xwm txheej no tam sim no yuav ncav cuag 10 txog 100 zaug ntawm cov qub kev ua haujlwm tam sim no ntawm lub zog hluav taws xob. Yog li, muaj tsawg kawg yog ob qhov teeb meem uas yuav tshwm sim. Firstly, yog tias DC cov khoom siv tsis tuaj yeem muab cov khoom pib txaus tam sim no, hloov hluav taws xob fais fab yuav nkag rau lub xeev xauv thiab tsis pib; Thib ob, qhov kev tawm tshiab tam sim no tuaj yeem ua rau muaj kev tiv thaiv lub zog hluav taws xob, uas yog qhov muaj peev xwm ua rau lwm cov khoom siv hluav taws xob siv lub zog qub tam sim ntawd.
Cov txheej txheem ib txwm muaj ntawm cov lus qhia tsis muaj kev txhawb nqa tam sim no yog txuas cov kub coefficient thermistor tam sim no liming cov (NTC) hauv koob. Txawm li cas los xij, cov qauv yooj yim no muaj ntau cov kev tsis muaj kev cuam tshuam ntawm NTC cov txiaj ntsig tau cuam tshuam nrog kev cuam tshuam rau cov ntc uas yog ib feem ntawm cov txiv ntseej cov kev cuam tshuam nrog kev hloov pauv hloov pauv ntawm cov khoom siv hluav taws xob. Qhov tseeb, ob qhov teeb meem tau hais los saum toj no tuaj yeem daws tau ntawm "muag muag muag", uas yuav qhia hauv kev nthuav dav hauv qab no.
Cov laj thawj rau nthwv tam sim no tiam nyob rau hauv hloov hom fais fab mov
Cov tswv yim hluav taws xob ntawm Hloov hom hwj huam uas feem ntau tau txais kev pab lub capacitic lim rectifier Circuitifi. Thaum lub sijhawm kaw cov khoom siv fais fab kev tuaj, vim yog thawj zaug ntawm lub capacitor tau xoom, muaj ib qho loj tshaj plaws yuav tsim tau thaum lub peev xwm ntawm lub capacitor. Tshwj xeeb tshaj yog rau high-fais hloov hom fais fab khoom, muaj peev xwm loj dua Xws li qhov loj tshaj plaws tam sim no tam sim no ntawm lub zog ntawm tuaj yeem ua rau cov tswv yim fuse kom tawg mus rau hlawv tawm mus rau qhov kev puas tsuaj rau cov choj rectifier; Cov mob me me tuaj yeem ua rau cov huab cua hloov mus ua tsis kaw. Qhov tshwm sim saum toj no tuaj yeem ua rau hloov fais fab tuag rau malfunction. Yog li ntawd, yuav luag txhua qhov hloov hluav taws xob muab tau cov khoom siv muag muag kom tiv thaiv surge rurents, kom ua haujlwm ib txwm muaj thiab muaj kev ntseeg siab ntawm kev siv fais fab ob txhais tes.
2. Hluav taws xob ua haujlwm siv hluav taws xob ntawm cov muag muag pib
Yog tias "muag muag muag" yog siv los tshem tawm cov xwm txheej tam sim no thaum lub sijhawm pib hloov cov teeb meem tam sim no ntawm kev hloov pauv cov qauv tam sim no tau hais txog saum toj no. Kev tswj hwm qhov pib-up hloov fais fab tuag los ntawm "muag muag pib" kom tshem tawm cov ntsiab lus nce qib ob zaug ntawm lub zog thaum muaj kev pab tau tam sim no. Yog tias lub nra tsis yog tsav, tam sim no thaum hloov hluav taws xob tau pib yog feem ntau me me. Feem ntau, qhov pib tam sim no yuav ua tau me dua li lub xeev khov kho tam sim no khaws cia siv hom no.
