Nyob rau hauv rooj plaub thaum lub cuab yeej nrog kev siv tsawg tam sim no yuav tsum muaj qhov hluav taws xob nyob ruaj khov, qhov hloov khoom siv fais fab tsis muaj hluav taws xob pom nws daim ntawv thov tswv yim. Muaj qee qhov tsis zoo, qhov hwj huam no tau siv dav hauv cov khoom siv hluav taws xob thiab xov tooj cua.
Kev ntsuas tau, qhov zoo thiab qhov tsis zoo
Cov khoom siv hluav taws xob rau ntau cov cuab yeej hluav taws xob tau ua raws li lub thawv hloov pauv tsis tau. Cov khoom siv hluav taws xob zoo li no tau tsim los ntawm kev ua haujlwm siab, qhov me me thiab qhov hnyav. Lawv yog cov ntseeg tau tshaj plaws txij li lawv tsis muaj lub ntsuas cua winding. Lub teb ntawm daim ntawv thov ntawm lub zog hloov pauv tsis muaj hluav taws xob yog cov khoom siv hluav taws xob tsawg xws li cov khoom siv roj, cov tub sab tswb lub teeb, cov teeb tsa tsev hauv tsev raws li cov lus tsa suab thiab lwm yam kev lag luam thiab xov tooj cua.
Lub tshuab hluav taws xob uas tsis muaj hluav taws xob tsis ntshai txog kev tsim tawm lub voj voog luv thiab lub ntsiab ntawm cov hluav taws xob. Xws li cov khoom siv hluav taws xob tau ua haujlwm twj ywm, vim nws yog qhov tsis txawv ntawm qhov hloov pauv, thiab nws ruaj khov heev. Nws yog qhov yooj yim rov hais dua vim nws muaj tsawg kawg ntawm cov seem siv. Tab sis lub ntsiab kom zoo dua ntawm cov hluav taws xob hloov pauv tsis txaus hluav taws xob yog tias cov khoom tso tawm tam sim no tuaj yeem hloov kho los ntawm kev xaiv tus kheej ntawm qhov muaj peev xwm xav tau.
Ib qho teeb meem tseem ceeb ntawm cov khoom siv hloov pauv tsis muaj zog yog lub suab nrov, uas cuam tshuam tsis zoo rau cov hluav taws xob sib ze ntawm lub cuab yeej. Yog li no, txhua lub hwj huam hluav taws xob no tau soj ntsuam kom nruj rau kev siv hluav taws xob nrog rau lwm yam khoom siv. Ib qho ntxiv, lub hwj huam hluav taws xob no tsis muaj qhov sib cais galvanic sib cais los ntawm cov kab hluav taws xob, uas yuav tsum muaj kev ceev faj heev ntawm kev ntsuas kev nyab xeeb thaum ua haujlwm nrog cov khoom siv no.
Kev ua haujlwm txuj ci
Cov khoom siv hloov hluav taws xob tsis zoo yog tsim kom ruaj khov qhov hluav taws xob nrog qhov tso tawm hluav taws xob tam sim no, muab lub zog txaus rau tus kheej lub zog hluav taws xob tsawg.
Thaum lub tshuab hluav taws xob hauv qhov hloov hluav taws xob tau txiav tawm ntawm lub tswv yim AC cov ntsiab lus, lub tshuab hluav taws xob hauv lub tshuab hluav taws xob tau tso tawm los ntawm kev sib txuas nrog cov khoom siv sib txuas nrog. Qhov no tshwm sim kom lub zog los tsis ceeb ib tus neeg los ntawm kev kov lub sib chwv sib txuas lus. Ntawm qhov tig rov qab tom ntej, qhov hloov hluav taws xob ntawm lub network ntawm 220 Volts tau muab thiab tua los ntawm lub zog los ntawm qhov ntsuas phom, tom qab ntawd, raug ncaj los ntawm tus choj diode, nws nkag mus hauv lub zener diode. Tom qab ntawd, tom qab ua tiav cov ripples thiab ruaj khov nrog cov capacitors, qhov yuav tsum ua kom ruaj khov ntawm 12 volts nyob ntawm qhov tawm ntawm cov fais fab. Yog li, nws nyuaj rau overestimate lub luag hauj lwm thiab qhov tseem ceeb ntawm cov khoom siv hluav taws xob hloov pauv.
