Lub Power Factor Corrector Ua li cas?

Power Factor Corrector (PFC) tau mob siab rau txhawm rau txhim kho lub zog ntawm lub zog hluav taws xob, ua kom cov txheej txheem siv hluav taws xob zoo dua. Raws li qhov taw qhia tseem ceeb rau kev ntsuas kev siv hluav taws xob, lub zog hluav taws xob yog qhov piv ntawm lub zog tiag tiag thiab lub zog pom tseeb. Nyob rau hauv luv luv, lub luag hauj lwm tseem ceeb ntawm lub hwj chim kho qhov cuab yeej yog los txo reactive hwj chim nyob rau hauv lub system, ua lub waveforms ntawm tam sim no thiab voltage zoo ib yam, thiab ntxiv txhim kho cov efficiency ntawm kev siv fais fab.
Cov lus piav qhia luv luv ntawm lub zog muaj zog
Kev siv hluav taws xob zoo (P) yog hais txog lub zog siv los ua haujlwm, thiab nws qhov ntsuas yog watt (W).
Hais txog lub zog reactive (Q): Nws tsis koom nrog qhov tso tawm hluav taws xob tiag tiag, tab sis nws cuam tshuam rau kev hloov pauv tam sim no hauv lub zog hluav taws xob, thiab ntsuas hauv var (VAR).
Lub zog pom tseeb (S) txhais tau tias yog lub zog tag nrho tsim los ntawm kev sib xyaw ua ke ntawm lub zog ua haujlwm thiab rov ua haujlwm, thiab nws chav tsev yog volt-ampere (VA).
Lub zog qhov tseem ceeb (PF) piav qhia qhov sib piv ntawm lub zog muaj txiaj ntsig thiab lub zog tiag tiag, uas tau hais tshwj xeeb raws li hauv qab no:
Lub zog tseem ceeb (PF) tuaj yeem txhais tau tias lub zog muaj zog (P), lub zog pom tseeb (S), lub zog muaj zog (PF), thiab kev sib xyaw ua ke ntawm lub zog muaj zog (P), pom meej zog (S), lub zog ua haujlwm (P) thiab pom meej zog (S). Ntawm lawv, lub zog qhov tseem ceeb (PF) yog qhov suav ntawm lub zog pom (S) thiab lub zog ua haujlwm (P).
Thaum tus nqi hluav taws xob tau muab faib rau hauv thaj tsam ntawm 0 thiab 1, tus nqi no yog siv los sawv cev rau lub xeev siv hluav taws xob zoo tshaj plaws. Thaum nws nyob ze rau 1, qhov no yuav ua rau lub waveforms ntawm tam sim no thiab voltage yuav luag synchronized, yog li txhim kho lub zog efficiency ntawm lub system. Yog tias lub zog ntawm qhov system qis qis, nws txhais tau hais tias yuav muaj lub zog siv ntau dua hauv qhov system, ua rau kev siv hluav taws xob tsis tsim nyog thiab txo qis hauv kev ua haujlwm ntawm lub zog.
Lub luag haujlwm tseem ceeb dab tsi yog lub hwj huam hloov kho lub zog?
Lub hwj chim yam corrector aims kom txo tau cov reactive zog nyob rau hauv lub system thiab optimize lub hwj chim yam. Nws lub luag haujlwm tseem ceeb tuaj yeem ua los ntawm ntau qib:
Ua kom muaj kev siv hluav taws xob ntau ntxiv:
Txo reactive zog txo qhov poob ntawm hluav taws xob lub zog, yog li txhim kho lub zog efficiency ntawm lub system. Kev txuag hluav taws xob tau ua tiav los ntawm kev txo cov khoom pov tseg tsis tsim nyog ntawm hluav taws xob hluav taws xob hauv kev ua haujlwm ntawm daim phiaj hluav taws xob.
Txo tus nqi hluav taws xob:
Cov tuam txhab muab hluav taws xob feem ntau them nqi ntxiv rau cov neeg siv khoom siv hluav taws xob tsawg vim tias lub zog hluav taws xob qis txhais tau hais tias daim phiaj hluav taws xob xav tau kom muaj lub zog pom tseeb dua. Thaum tus nqi hluav taws xob qis dua ib qho nqi, tej zaum yuav muaj nqi ntxiv. Kev kho kom raug ntawm lub zog muaj peev xwm tuaj yeem txo cov nuj nqis ntxiv no.
Txhim khu lub zog siv efficiency ntawm lub hwj chim system:
Hauv lub zog hluav taws xob, thaum lub zog reactive txo, qhov kev thov tam sim no kuj yuav txo qis, thiab qhov no tseem yuav ua rau txo qis ntawm cov khoom siv hluav taws xob xws li transformers thiab cables, uas tuaj yeem txhim kho lub peev xwm siv cov khoom siv fais fab thiab zam cov khoom siv overload teeb meem tshwm sim los ntawm lub zog reactive ntau dhau.
Extend lub neej ntawm cov khoom siv:
Ua tsaug rau qhov txo qis ntawm lub zog reactive, tus nqi ntawm cov khoom siv hluav taws xob tam sim no raug txo, uas yuav pab txo qhov poob ntawm cov khoom siv hluav taws xob (xws li transformers, generators, thiab lwm yam) thiab tag nrho lub zog hluav taws xob, yog li txuas ntxiv lub neej kev pab cuam. ntawm cov khoom siv no.
Txo qhov loj ntawm cov cuab yeej hluav taws xob:
Tom qab cov khoom siv hluav taws xob hauv lub zog tau txhim kho, cov nqi tam sim no raug txo, uas tuaj yeem txo qhov loj ntawm cov khoom siv hluav taws xob xws li cables, transformers, generators, thiab lwm yam, yog li txo qhov cuam tshuam ntawm kev tsim kho thiab tu cov nqi.
Hom lus piav qhia Lub Hwj Chim Factor Corrector
Passive Energy Power Factor Corrector:
Los ntawm kev siv cov khoom siv wireless xws li capacitors thiab inductors los txhim kho lub zog, peb tuaj yeem txhim kho lub zog zoo dua. Passive PFC feem ntau yog tsim rau cov kab ke yooj yim nrog cov khoom ruaj khov thiab tsis tshua muaj zog.
Qhov zoo: tus nqi pheej yig thiab kev ua haujlwm yooj yim thiab txhim khu kev qha.
Disadvantages: txwv adaptability, tsis tuaj yeem hloov mus rau ntau qhov kev hloov pauv, thiab yuav tsum tau hloov kho phau ntawv.
Calibration cuab tam nrog lub zog qhov tseem ceeb:
Los ntawm kev siv lub tshuab hluav taws xob tswj hluav taws xob nrog cov khoom siv hluav taws xob sib xyaw ua ke (xws li transistors, diodes, thiab keyboards), tam sim no waveform tuaj yeem hloov kho dynamically. Cov cuab yeej no feem ntau haum rau cov tshuab uas xav tau kev ua haujlwm zoo thiab muaj kev hloov pauv loj.
Qhov kom zoo dua yog nws cov kev ua tau zoo, muaj peev xwm hloov mus rau cov khoom tsis sib xws, thiab lub zog ntawm ze li 1.
Qhov tsis zoo yog tias nws kim heev thiab ntsib teeb meem loj hauv kev tsim thiab kho.
Thaum siv cov khoom siv hluav taws xob hloov kho
Hauv kev lag luam, xws li motors, compressors, thiab twj tso kua mis, cov cuab yeej no feem ntau dais loj inductive loads, yog li lawv lub zog tseem ceeb kuj tsawg. Nrog kev pab los ntawm PFC thev naus laus zis, kev ua haujlwm ntawm cov cuab yeej no tuaj yeem txhim kho tau zoo.
Hauv ntau cov khoom siv hluav taws xob, xws li khoos phis tawj, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob LED, cov khoom siv hluav taws xob tsis zoo feem ntau tshwm sim, uas ua rau txo qis zog theem. PFC tuaj yeem txhim kho qhov zoo ntawm lub zog ntawm cov khoom siv hauv tsev.
Hais txog kev sib kis thiab kev faib hluav taws xob: Hauv tag nrho lub zog hluav taws xob, lub zog hluav taws xob tsawg tuaj yeem ua rau cov khoom thauj khoom ntawm cov khoom siv hluav taws xob ntau dua, ua rau lub zog xa hluav taws xob ntau dua. Txhim kho PFC cov cuab yeej siv tsis tau tsuas yog ua kom zoo dua ntawm cov ntaub ntawv xa mus, tab sis kuj txo cov kev siv hluav taws xob.
Los xaus
Cov khoom siv hluav taws xob hloov hluav taws xob yog qhov tseem ceeb hauv kev txhim kho cov khoom siv hluav taws xob hauv lub zog hluav taws xob, txo cov hluav taws xob reactive, txhim kho tag nrho cov kev ua tau zoo ntawm lub zog, txo qis hauv kev xa hluav taws xob, thiab txo cov nqi hluav taws xob ntxiv. Lawv kuj yog ib qho tseem ceeb hauv kev ncua kev pab cuam lub neej thiab kev ua tau zoo ntawm cov khoom siv fais fab. Rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov tshuab hluav taws xob loj, kev siv cov khoom siv hluav taws xob yog qhov tseem ceeb tshwj xeeb, tshwj xeeb tshaj yog thaum ntsib cov teeb meem tsis muaj zog lossis kev hloov pauv ntau dhau.
