Qhov zoo ntawm hluav taws xob ballast
Kev txuag hluav taws xob
A. Hluav taws xob ballast tau txais yuav, lub zog ntawm cov kab yog siab dua 0.99, lub npe tam sim no ntawm cov kab me me, thiab lub zog poob ntawm txoj kab thiab kev faib hluav taws xob yog txo.Yog li ua kom tiav lub hom phiaj ntawm kev txuag hluav taws xob.
B. Lub zog poob ntawm cov hluav taws xob ballast yog qhov tsawg tshaj li ntawm inductive ballast.Piv txwv li, 250W hluav taws xob ballast muaj qhov poob ntawm 6 ~ 11W, thaum lub inductive ballast poob ntawm 38W.
C. Thaum lub teeb hluav taws xob siv hluav taws xob sib xyaw ua ke nrog cov hluav taws xob ballast, nws qhov kev ua tau zoo ntawm lub teeb yog 1.10, thaum nws sib phim nrog cov inductive ballast, nws qhov sib piv ntawm lub teeb pom kev zoo nyob nruab nrab ntawm {{7} 0.98 thiab 95. Yog li ntawd, lub luminous efficiency ntawm lub high-siv paug teeb yuav tsum tau nce los ntawm ntau tshaj 10 feem pua tom qab lub hluav taws xob ballast tau txais yuav.
Cov zis hluav taws xob tas li zoo heev txhim kho kev ua haujlwm ntawm lub teeb
A. Khaws cov xim ntawm lub teeb, xws li xim kub thiab xim rendering, zoo ib yam thoob plaws lub neej ntawm lub teeb los ntawm kev ua kom lub raj kub tsis tu ncua.
B. Ua kom ntev lub neej kev pab cuam ntawm lub teeb.Nrog cov hluav taws xob ballast, lub teeb hluav taws xob siv hluav taws xob ua haujlwm tsis tu ncua, ua rau nws lub neej kev pab ntau tshaj 1.5 npaug ntawm nws lub neej nominal.
C. Kev khiav hauj lwm ntau zaus ntawm lub voj voog tshem tawm qhov tshwm sim strobe tshwm sim hauv kev siv cov teeb hluav taws xob siv siab ua ke nrog inductive ballasts.
Disadvantages ntawm electronic ballast:
tus nqi siab dua
Txoj hauj lwm tsis ruaj khov, yooj yim mus yuam kev, tag nrho lub neej luv luv
Nyob rau hauv thawj ib nrab ntawm 2003, lub tuam txhab tau sim cov hluav taws xob ballasts ntawm txawv powers los ntawm ob peb manufacturers nyob rau hauv Tuam Tshoj, xws li platon, jilida, baode thiab lwm yam manufacturers.Laboratory xeem cov qhabnias qhia tau hais tias cov hluav taws xob ballast yog tsis ruaj tsis khov thiab nquag ua tsis tiav.Qhov siab tshaj plaws lub neej. cog lus los ntawm cov chaw tsim khoom tsuas yog peb xyoos.
Txawm hais tias hluav taws xob ballast muaj qhov tsis zoo nyob rau theem tam sim no, los ntawm qhov kev xav ntawm cov nqi sib tw, kev siv hluav taws xob ballast muaj qhov txiaj ntsig zoo, nws sawv cev rau kev txhim kho yav tom ntej ntawm ballast, yuav muaj kev cuam tshuam deb ntawm kev txhim kho yav tom ntej. hluav taws xob lub teeb ci kev lag luam.
Electronic triggers thiab capacitor
Feem ntau cov teeb hluav taws xob siv hluav taws xob ntau, xws li cov teeb hluav taws xob siab siab, cov teeb hluav taws xob hlau halide, thiab lwm yam, yuav tsum muaj qhov hluav taws xob ntau dua li qhov hluav taws xob hluav taws xob hluav taws xob pib. Feem ntau ntau hom HID teeb yuav tsum tau ntxiv {{0} }.6 ~ 5.0kV pulse high voltage.Ib lub tshuab hluav taws xob yog ib qho khoom siv uas tsim cov mem tes ntawm kev kub siab los pib lub teeb pom kev zoo.Thaum lub teeb ignites, pulse voltage ploj mus thiab lub tshuab hluav taws xob tsis ua haujlwm.
Lub pulse generated los ntawm lub trigger yog ib tug high-frequency mem tes, thiab lub faib capacitance ntawm lub Circuit Court muaj ib tug zoo heev cuam tshuam rau nws. Ib tug loj faib capacitance yuav ua rau lub mem tes amplitude attenuation thiab lub teeb yuav pib tsis tau.Feem ntau, cov faib capacitance ib meter ntawm lub Circuit Court yog mus txog 70 ~ 100PF. Tus neeg siv yuav tsum txiav txim siab qhov ntev ntawm lub voj voog raws li qhov nominal tso cai load capacitance tus nqi ntawm tus trigger.Yog hais tias tus nqi nominal yog 20 ~ 1000PF, txoj kab ntev yuav tsum tswj tsis pub dhau 10 meters (qhov kev ncua deb ntawm qhov ua rau lub teeb).
Lub luag haujlwm tseem ceeb ntawm kev muaj peev xwm nyob rau hauv daim duab schematic ntawm European tus qauv inductance ballast yog lub zog them nyiaj los txhim kho cov khoom siv hluav taws xob ntawm lub voj voog.Inductive ballast yog inductive load, lub hwj chim yam tsawg heev, tsuas yog {{0} }.
Lub capacitor nyob rau hauv daim duab schematic ntawm American standard inductance ballast yog lub capacitor ua hauj lwm, uas ua ke nrog cov inductance nyob rau hauv lub ballast tsim LC ua lub ncov ballast.
Fais fab xwm txheej
Lub zog tseem ceeb yog hais txog qhov piv ntawm lub zog ua haujlwm rau lub zog pom tseeb. Input power factor yog ib qho tseem ceeb index. Kev txhim kho qhov ntsuas no tuaj yeem tsis tsuas yog txo cov kab poob, txuag hluav taws xob, tshem tawm qhov phom sij ntawm hluav taws, tab sis kuj txo qis kev sib raug zoo ntawm cov khoom siv hluav taws xob, txhim kho cov khoom siv hluav taws xob zoo, thiab tau txais txiaj ntsig zoo ntawm kev lag luam thiab kev sib raug zoo. Qhov zoo tshaj plaws input zog yam yog 1.
