Lub apparatus thiab Circuit Court ntawm lub fluorescent teeb

Lub fluorescent teeb (ll) yog ib lub teeb qhov chaw generated los ntawm hluav taws xob paug nyob rau hauv ib tug nruab nrab ntawm mercury vapor thiab inert roj. Qhov no seb puas tsimnyog tau cov invisible ultraviolet illumination acting nyob rau hauv lub phosphor txheej loj hauv lub iav hwj. Ib tug raug Circuit Court ntawm lub fluorescent teeb ballast yog ib tug ntaus nrog electromagnetic ballast (EmPRA).

Ntaus kev piav qhia thiab ll

Feem ntau cov teeb teeb yeej ib txwm muaj ib tug cylindrical zoo, tab sis tam sim no nws yuav ua tau nyob rau hauv daim ntawv ntawm ib tug complex daim duab. Thaum lub xaus ntawm lub electrodes mounted nyob rau hauv nws, structurally txog rau ib co ntawm cov kauv filament teeb ua los ntawm tungsten. Lawv soldered mus rau lub pins nyob rau sab nraum, uas ib tug voltage yog thov.

Gas conductive nruab nrab hauv ll muaj ib tug tsis zoo ua hauj. Nws manifests nws tus kheej nyob rau hauv lub yuav txo tau ntawm lub voltage ntawm lub opposing electrodes nrog ib qho kev nce ntawm cov tam sim no uas yuav tsum tau txwv. Scheme incorporating fluorescent teeb comprises ballastnik (zawm caj pas yog), cov hom phiaj tseem ceeb ntawm uas - cov creation ntawm ib tug loj voltage mem tes rau nws tiv cav tseb. Dhau li nws yog muaj nyob rau hauv EmPRA oob khab - ci teeb tso rau hauv nws nrog ob tug electrodes nyob rau hauv ib tug inert roj cua. Ib tug ntawm lawv yog ua los ntawm bimetal. Nyob rau hauv lub xeev pib yog qhib electrodes.

Cov kev khiav hauj lwm hauv paus ntsiab lus ntawm lub ll

Lub oob khab Circuit Court ntawm lub fluorescent teeb ua hauj lwm raws li nram no.

1. Nyob rau hauv Circuit Court yog energized, tab sis tus thawj los ntawm ll tam sim no tsis yog vim lub loj kuj ib puag ncig. Los ntawm qwj cathode tam sim no kis thiab heats lawv. Tsis tas li ntawd, nws kuj yog txhab khoom mus rau oob khab uas cov mov voltage yog txaus rau originated nyob rau hauv lub glow tawm.
2. Thaum cua sov rau cov oob khab hu los dua tam sim no bimetallic phaj kaw. Tom qab ntawd, cov hlau xyuas pib yuav, thiab lub paug yog haujlwm.
3. Lub bimetallic electrode cools down thiab qhib kev sib cuag. Thaum zoo li no zawm caj pas yog outputs ib tug high voltage mem tes vim rau nws tus kheej-inductance, thiab dhau yog Cov nroj cig cuag.
4. Nws mus los ntawm lub teeb tam sim no uas yog ces txo mus rau 2 lub sij hawm, raws li voltage thoob plaws lub inductor ntog. Nws yog tsis txaus mus pib dua lub oob khab hu uas nyob twj ywm qhib thaum lub sij hawm combustion dhau.

Lub tswvyim ntawm cov menyuamuas ntawm luminescent teeb ntawm ob ntsia tau rau hauv ib tug luminaire, yuav siv ntawm lawv rau ib qho kev zawm caj. Lawv muaj kev cob cog nyob rau hauv series, tab sis txhua teeb ntsia rau ntawm ib thaum uas tig mus pib.

Lub disadvantage ntawm lub teeb yog tawm ntawm lub thib ob valve, Yog hais tias ib tug ntawm lawv tau ua tsis tau tejyam.

Tseem Ceeb! Nrog fluorescent teeb yuav tsum tau siv tshwj xeeb keyboards. Nyob rau hauv Kaum Ob Lub Hlis pab kiag li lawm pib currents yog loj, thiab hu yuav ua tau nplaum.

Throttle-free fluorescent teeb menyuamuas: schema

Dua li ntawm qhov uas tsis muaj nqi, electromagnetic ballasts muaj drawbacks. Lawv yog cov yog vim li cas rau lub creation ntawm hluav taws xob circuits ntawm ignition (ECG).

Yuav ua li cas khiav rau ll nrog rau hauv ballasts

Throttle-free menyuamuas ntawm fluorescent teeb ua los ntawm cov hluav taws xob kev tswj chav tsev, uas generates ib theem ntawm cov voltage hloov thaum lub sij hawm lawv cov tiv cav tseb.

Qhov zoo ntawm e-tsav Circuit Court:

• tau mus pib los ntawm tej lub sij hawm ncua;
• Peb tsis xav tau ib tug loj heev electromagnetic throttle thiab oob khab;
• tsis muaj buzzing thiab blinking teeb;
• siab luminous efficiency;
• lightness thiab compactness ntawm tus dais;
• ib tug ntau dua lub neej.

Niaj hnub nimno hauv ballasts muaj ib tug compact loj thiab tsis muaj zog noj. Lawv hu ua cov neeg tsav tsheb, muab rau hauv lub hauv paus ntawm txoj kev cog lus ntawm teeb. Throttle-free incorporation ntawm fluorescent teeb tso cai rau kev siv ntawm cov pa txheem cartridges.

Hauv ballast system converts ib alternating voltage network 220 rau siab zaus. Thawj dhau electrodes yog rhuab, thiab ces noj ib high voltage. Thaum loj efficiency yog nce thiab flicker yog tshem tawm kiag li. Scheme menyuamuas ntawm lub fluorescent teeb yuav muab ib tug txias pib los yog ib tug tus nce brightness. Nyob rau hauv thawj cov ntaub ntawv, lub lag luam ntawm lub electrode lub neej yog significantly txo.

Tus muaj zog voltage nyob rau hauv lub tshuab hluav taws xob Circuit Court yog tsim los ntawm lub oscillation Circuit Court, ua rau resonance thiab teeb tiv cav tseb. Lub community launch yuav siv sij hawm qhov chaw yooj yim npaum li nyob rau hauv lub classical tswvyim nrog ib tug electromagnetic throttle. Ces, raws li cov voltage txo rau cov yam nqi ntawm cov paug tuav tseg.

Voltage rectification yog ua los ntawm lub diode choj, tom qab uas nws yog smoothed thaum uas tig mus kev cob cog rua capacitor C _1. Tom qab txuas mus rau lub network tam sim ntawd them capacitor C ₄ thiab so dynistor. Sau ntawm ib nrab-choj generator transformer TR ₁ thiab cov transistors T ₁ thiab T _2. Thaum xeeb 45-50 kHz zaus yog generated siv cov serial resonance Circuit Court c C _2, C _3, L _1, kev cob cog rua rau lub electrodes, thiab lub teeb ignites. Nyob rau hauv no cov tswvyim kuj muaj ib tug caj pas, tab sis, nrog me me qhov ntev, qhov uas koj yuav muab nws nyob rau hauv lub teeb puag.

Hauv ballast muaj adjusts lub ll li tus yam ntxwv hloov. Tom qab ib lub sij hawm yuav tsum tau rau lov teeb voltage nce rau tiv cav tseb. Nyob rau hauv Scheme EmPRA nws tsuas yuav tsis khiav, thiab cov hluav taws xob ballast yog cov txheej txheem ntawm nyob rau hauv kev hloov yam ntxwv thiab yog li enables cov ntaus ntawv mus rau koj khiav lag luam nyob rau hauv dej siab tej yam kev mob.

Qhov zoo ntawm cov niaj hnub hluav taws xob ballasts yog raws li nram no:

• mos pib;
• kev khwv nyiaj txiag ntawm lub lag luam;
• preservation ntawm electrodes;
• kos flicker;
• operability ntawm ib tug tsawg kub;
• compactness;
• durability.

Qhov tsis zoo yog tus nqi siab thiab txoj Circuit Court tiv cav tseb.

Daim ntawv thov ntawm ib tug voltage d

Cov kev ua rau nws ua tau rau muaj xws li electromagnetic ll tsis ballast, tab sis yog dua li siv los cas sim haum lub neej ntawm lub teeb. Circuit Court ntawm lub burnt tawm fluorescent teeb tso cai rau lawv ua hauj lwm rau tej lub sij hawm, yog hais tias tus hwj chim tsis pub tshaj 20-40 watts. Nyob rau hauv rooj plaub no tus filament tej zaum yuav yog lawm los yog cua tshuab. Nyob rau hauv ob qho tib si zaum, qhov kev cov lus xaus ntawm txhua filament yog tsim nyog los luv luv-Circuit Court.

Tom qab tiav lub voltage yog ob npaug, thiab lub teeb teeb li instantly. Capacitors C _1, C ₂ yog raug xaiv mus rau lub operating voltage ntawm 600 V. Lawv drawback yog cov loj loj. Lub capacitors C _3, C ₄ mounted rau mica 1000 V.

Ll yog tsis npaj rau direct tam sim no fais fab mov. Thaum lub sij hawm, cov tshuaj mercury accumulates nyob ze ib tug ntawm cov electrodes, thiab cov glow ntawm weakening. Yuav kom restore hloov cov polarity reversing lub teeb. Nws yog ua tau rau teem tus tes hloov qhov thiaj li hais tias nws tsis tua.

Besstarternaya tswvyim Cov menyuamuas ntawm luminescent teeb

Scheme oob khab yuav tsum tau ib tug ntev sov-up teeb. Nyob rau hauv tas li ntawd, nws yog tej zaum tsim nyog hloov. Nyob rau hauv no kev twb kev txuas, muaj lwm cov tswvyim nrog rhuab electrodes los ntawm ob winding ntawm lub transformer, uas kuj ua rau cov kev ua ntawm lub ballast.

Thaum tus tes hloov qhov no yog ua los ntawm fluorescent teeb tsis muaj oob khab, lawv yuav tsum RS los (ceev pib). Teeb nrog oob khab community launch yuav tsis ua hauj lwm no raws li ntev raws li nws cov electrodes yog rhuab, thiab cov kauv sai sai hlawv.

Yuav ua li cas tig rau lub teeb burnt?

Yog hais tias muab kauv tawm ntawm kev txiav txim, dhau yuav cig tsis muaj ib tug voltage d, siv li ib txwm tswvyim EmPRA. Scheme pab kom cov fused fluorescent teeb txawv me ntsis xwb yog muab piv rau cov pa. Rau lub hom phiaj no, lub oob khab capacitor kev cob cog rua nyob rau hauv series, thiab electrode pins yog cov luv luv-circuited. Tom qab xws li ib tug me me kev hloov lub teeb yuav kav rau ib lub sij hawm.

xaus

Tsim thiab Circuit Court ntawm lub fluorescent teeb yog lossi tau zoo tuaj ntawm lub kev khwv nyiaj txiag, txo qhov luaj li cas thiab ua cov kev pab cuam lub neej. Nws yog ib qho tseem ceeb rau kev siv nws, kom to taub nyob rau hauv ib tug ntau yam ntawm hom ua thiab paub zoo txoj kev mus cuag.
