Lub zog tsim (pf)Hauv kev hloov pauv yog kev ntsuas ntawm cov hluav taws xob hluav taws xob tau siv. Nws yog tus piv ntawmLub zog tiag tiag (nquag siv zog)raupom meej lub zog, thiab nws qhia tau cov efficiency ntawm fais fab hloov hauv lub system.
Cov Ntsiab Lus Tseem Ceeb:
Lub Zog tiag tiag (P):
Ntsuas hauvWatts (w).
Sawv cev rau lub zog tiag tiag tau noj los ntawm lub nra ua haujlwm kom muaj txiaj ntsig zoo.
Rease Fais Fab (Q):
Ntsuas hauvVolt {{0} ignes reactive (var).
Sawv cev lub zog siv los tswj cov tshuab hluav taws xob hauv inductive lossis capactrativitive thauj khoom (piv txwv li, cov hloov pauv).
Pom muaj zog:
Ntsuas hauv{{0} ece} Amperes (VA).
Kev sib xyaw ntawm lub zog tiag tiag thiab cov hluav taws xob ua kom muaj zog, suav nrog:
S=P2+Q2S=P2+Q2
Lub Zog Factor Mis:
Lub Zog Hluav Taws Xob (PF)=Lub Zog (P) Lub Zog (P) Lub Zog (PF)
Lub hwj chim muaj txiaj ntsig los ntawm0 txog 1.
A pf ntawm1qhia tau zoo tshaj plaws efficiency (tsis muaj reflective zog).
A pf ntawm0Qhia txhua lub zog yog reactive (tsis muaj txiaj ntsig ua tiav).
Qhov tseem ceeb ntawm lub hwj chim hauv kev hloov pauv:
Ua tau zoo:
Lub zog loj txhais tau tias yog transformer yog siv hluav taws xob hluav taws xob ntau dua.
Tsawg siv lub zog ua kom muaj peev xwm ua kom muaj zog dua thiab txo qis.
Nqi txuag:
Cov nqi hluav taws xob feem ntau them cov kev nplua rau qhov tsis tshua muaj zog, raws li nws nce lub nra ntawm cov phiaj xwm fais fab.
Txhim kho cov khoom siv fais fab txo cov nqi hluav taws xob txo cov nqi hluav taws xob.
Khoom Tiv Thaiv Khoom:
Tsawg lub zog siv tau tuaj yeem ua rau muaj kev kub ntxhov thiab kev puas tsuaj rau cov hloov khoom thiab lwm yam khoom siv.
Tswj lub zog loj ua kom pom tseeb cov cuab yeej siv sijhawm ntev.
Yuav ua li cas txhawm rau txhim kho lub zog muaj zog:
Kev Tsim Kho Lub Zog (PFC):
Nruab capacitors lossis synchronous condensers kom txhawb nqa hluav taws xob.
Qhov no txo cov theem sib txawv ntawm voltage thiab tam sim no.
Kev Tswj Xyuas:
Zam kev ua haujlwm hloov pauv ntawm cov thauj khoom tsis muaj zog heev lossis overloading lawv.
Txhim kho lub thauj khoom kom ua haujlwm ze nws lub peev xwm.
Siv high -} efficymess cov khoom siv:
Niaj hnub niaj hnub hloov pauv thiab lub cev muaj zog yog tsim nrog cov yam ntxwv zoo zog muaj zog.
Ntsiab lus:
Lub zog muajyog qhov ntsuas tseem ceeb hauv kev hloov pauv, xav txog kev siv fais fab.
Ib lub zog loj txhim kho cov zog txuag hluav taws xob, txo cov nqi, thiab cov khoom siv tiv thaiv.
Cov Kev Tsim Kho Kev Tsim Kho Kev Tsim Kho yog qhov tseem ceeb rau kev tswj cov kev ua tau zoo tshaj plaws.
