Chav kawm ntawm DC tswj fais fab mov thiab nws txoj kev xaiv

ଲେଖକ: ଆଇଫ୍ଲୋପାୱାର - Furnizor centrală portabilă

Kev nce qib ntawm tib neeg lub neej yog sib cais los ntawm txhua qhov chaw ntawm lub neej, thiab kev hloov tshiab ntawm ntau yam khoom siv hluav taws xob yuav tsis qhib peb tus tsim lub dag zog. Qhov tseeb, ntau tus neeg yuav tsis nkag siab txog cov khoom siv hluav taws xob, xws li DC. Fais fab mov.

Stabilized fais fab mov muaj ntau txoj kev faib. Raws li hom tso zis fais fab mov, muaj DC voltage regulator fais fab mov thiab AC regulator fais fab mov. Raws li txoj kev sib txuas ntawm lub regulator Circuit Court thiab load DC tswj fais fab mov, nws tuaj yeem muab faib ua cov khoom siv hluav taws xob thiab hluav taws xob sib txuas.

Raws li kev khiav hauj lwm lub xeev ntawm lub raj hloov, muaj ib tug linear hloov ntawm lub hwj chim mov thiab hloov mus kho lub hwj chim mov. Raws li hom Circuit Court, muaj qhov yooj yim voltage tswj fais fab mov thiab tawm tswv yim regulator fais fab mov, thiab lwm yam. Xws li ntau hom kev faib tawm feem ntau ua rau cov neeg pib xav tsis meej pem thiab xav paub seb yuav pib qhov twg.

Qhov tseeb, nws yuav tsum tau hais tias cov kev faib tawm zoo li no muaj qee qhov kev sib raug zoo, tsuav yog qhov kev sib raug zoo no tau qhia meej, hom khoom siv hluav taws xob tuaj yeem muab faib ua ib txwm muaj. Txij li thaum peb tab tom tham txog kev faib tawm ntawm kev tswj hwm lub zog, peb yuav tsum xub nkag siab txog qhov tso zis ntawm lub zog hluav taws xob yog tso tawm DC lossis hloov hluav taws xob. Ua li no, thawj txheej tuaj tawm.

Ua ntej, koj yuav tsum tau faib raws li cov zis hom ntawm lub hwj chim mov. Qhov kev faib tawm tom ntej yog teeb meem ntau dua. Puas yog nws cais raws li lub xeev kev khiav hauj lwm ntawm lub regulator Circuit Court thiab lub load kev twb kev txuas txoj kev los yog tus adjuster? Qhov tseeb, yog tias koj nkag siab txog cov khoom siv hluav taws xob nyob ib puag ncig peb, yuav muaj ob qhov sib txawv hauv kev siv tiag tiag ntawm cov khoom siv hluav taws xob ruaj khov.

Muaj ntau yam khoom siv hluav taws xob tswj hluav taws xob, tau siv dav hauv ntau yam khoom siv hluav taws xob yooj yim, xws li xov tooj cua, hais lus me me, thiab lwm yam .; ib qho yog siv dav hauv ntau yam khoom siv hluav taws xob, xws li cov ntxaij vab tshaus loj Xim TV, microcomputer, thiab lwm yam. Nyob rau hauv txoj kev no, peb tuaj yeem faib qib thib ob raws li kev ua haujlwm ntawm lub tshuab hloov kho.

Cov chav kawm thib peb tom ntej no tau muab cais raws li kev tswj hwm Circuit Court thiab hom kev sib txuas ntawm kev thauj khoom. Txij li cov yam ntxwv ntawm ntau yam sib txawv circuits yog loj heev, ntxiv subdivision tsis yooj yim rau general, thiab yuav tsum tau muab cais raws li cov yam ntxwv ntawm txhua chav kawm ntawv. DC voltage regulator fais fab mov tuaj yeem muab faib ua cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ruaj khov thiab hloov cov khoom siv hluav taws xob ruaj khov, uas muaj ntau yam: tshuaj siv hluav taws xob peb feem ntau siv cov roj teeb qhuav, cov roj ntsha lead-acid, nickel-cadmium, nickel-hydrogen, lithium ions Battery belongs rau qhov no, txhua tus muaj nws tus kheej zoo.

Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, cov roj teeb ntse tau tsim. Hais txog cov khoom siv roj teeb rov qab, Asmeskas cov neeg tsim khoom tau tshawb pom manganese iodide, manganese siv rau hauv pheej yig, compact, tawm lub sij hawm thiab tswj kev ua tau zoo tom qab them nyiaj ntau. Zoo ib puag ncig tus phooj ywg rechargeable roj teeb.

Ib qho tshwj xeeb ntawm cov kab hluav taws xob tswj hluav taws xob linear tswj fais fab mov yog nws cov khoom siv hluav taws xob tswj hluav taws xob hauv cheeb tsam linear, tso siab rau lub siab poob ntawm lub regulator raj kom ruaj khov cov zis. Txij li thaum lub electrostatic poob ntawm kev hloov lub raj yog loj, nws yog ib qho tsim nyog yuav tsum tau nruab ib lub dab dej loj rau cua sov. Ntxiv mus, txij li thaum lub transformer ua hauj lwm nyob rau hauv lub hwj chim zaus (50 Hz), qhov hnyav kuj loj.

Qhov zoo ntawm cov khoom siv hluav taws xob no yog kev ruaj ntseg siab, me me ripple, muaj kev ntseeg siab, yooj yim los ua ntau cov channel, thiab cov khoom tsim tawm. Qhov tsis zoo yog tias nws loj, cumbersome thiab efficiency yog tsawg. Lub zog ruaj khov no muaj ntau yam.

Los ntawm cov khoom tsim tawm, nws tuaj yeem muab faib ua cov khoom siv hluav taws xob tswj hwm thiab cov khoom siv hluav taws xob tsis tu ncua, nrog rau qhov ntsuas hluav taws xob ruaj khov thiab tsis tu ncua tam sim no (dual steady) cov khoom siv hluav taws xob ua ke nrog kev ruaj ntseg hluav taws xob thiab lub xeev ruaj khov. Nyob rau hauv cov nqe lus ntawm tus nqi tso zis, nws yuav muab faib ua taag-point tso zis fais fab mov, band hloov hloov thiab potentiometer nruam hloov hom. Los ntawm cov lus qhia tso zis tuaj yeem muab faib ua pointer indication type thiab digital display type, thiab lwm yam.

Hloov-hom DC voltage regulator fais fab mov thiab linear ruaj khov fais fab mov yog cov khoom siv ruaj khov sib txawv los hloov-hom DC stabilization fais fab mov. Nws hom Circuit Court yog ib qho tseem ceeb xws li ib leeg-kawg ya, ib leeg-kawg, ib nrab-choj, thawb-rub thiab tag nrho tus choj. Nws yog qhov sib txawv ntawm cov khoom siv hluav taws xob linear uas nws lub tshuab hloov pauv tsis ua haujlwm ntawm kev ua haujlwm zaus, tab sis ua haujlwm ntawm ob peb kaum ntawm kilohertz mus rau ob peb megabottomes.

Lub raj ua haujlwm tsis ua haujlwm nyob rau hauv qhov chaw saturation thiab txiav tawm (piv txwv li, lub xeev hloov); lub switching fais fab mov muaj npe. Qhov zoo ntawm cov khoom siv hluav taws xob hloov pauv me me, lub teeb yuag, ruaj khov thiab txhim khu kev qha; Qhov tsis zoo yog tias qhov ripple ntau dua li cov khoom siv hluav taws xob tawm (feem ntau ≤1% Vo (PP), zoo ripple yuav ntau dua 10mV (PP) lossis tsawg dua). Nws lub zog muaj peev xwm ua tau los ntawm ob peb watts mus rau ntau txhiab vuas.
