Daig caj pas rau fluorescent teeb: hom pab kiag li lawm, lub hom phiaj ntawm lub tswvyim thiab kev txheeb xyuas

Fluorescent teeb (LDS) - qhov no yog thawj tus nqi seev uas muaj emerged tom qab cov tsoos teeb nrog filament. Lawv mus rau lub paug ntaus ntawv, nyob rau tas yuav tsum tau caij nyob rau hauv lub hwj chim txawj Circuit Court.

lub sij hawm throttle

Zawm caj pas yog rau daylight teeb ntawm lwm yam uas lub voltage thov mus rau lub teeb electrodes. Nyob rau hauv tas li ntawd, nws muaj cov nram qab no:

• tiv thaiv tawm tsam voltage surges;
• cua sov rau cov cathodes;
• creation ntawm ib tug high voltage yuav pib lub teeb;
• txwv tsis pub hluav taws xob tam sim no tom qab start-up;
• Teeb stabilization ntawm lub combustion txheej txheem.

Kom txuag tau tus throttle yog kev cob cog rua rau ob lub teeb.

Cov kev khiav hauj lwm hauv paus ntsiab lus ntawm lub electromagnetic ballast (EmPRA)

Tus thawj tswvyim pib fluorescent teeb, uas yog tsim thiab siv kom txog thaum tam sim no, muaj xws li cov ntsiab:

• throttle;
• oob khab;
• ob capacitors.

Scheme teeb nruab hnub nrig nrog ib tug throttle kev cob cog rua rau lub network 220 V. Tag nrho qhov chaw tuaj koom ua ke hu ua electromagnetic ballast.

Thaum cov mov Circuit Court yog kaw qwj tungsten teeb, thiab yog muaj nyob rau hauv lub glow paug oob khab hom. Tam sim no los ntawm lub teeb yog tsis tau noj qhov chaw. Lub filaments yog rhuab maj. oob khab hu yog qhib nyob rau hauv lub xeev pib. Ib tug ntawm lawv ua ib tug bimetallic. Nws bends thaum rhuab los ntawm lub glow paug thiab muab kaw rau hauv Circuit Court. Thaum zoo li no tam sim no nce los ntawm 2-3 lub sij hawm thiab lub teeb cathodes yog rhuab.

Raws li xwb kaw oob khab sib cuag, nws nres lub paug, thiab cov bimetallic phaj pib kom txias. Raws li ib tug tshwm sim, lub rooj noj hu yog qhib thiab lub caj pas inductance tshwm sim ib tug txiav txim voltage mem tes. Nws yog txaus tias qhov electrons ntaus gaseous nruab nrab ntawm lub electrodes thiab lub teeb twb kaj. Tom qab nws pib kom dhau lub nyob tam sim no, uas yog ces txo mus rau 2 lub sij hawm vim lub voltage nco thoob plaws lub inductor. Lub oob khab tshua mus tas li hloov tawm (hu qhib), thaum LDS kub yus.

Yog li, lub ballast teeb pib thiab tom qab yuav nws nyob rau hauv ib tug active lub xeev.

Zoo thiab tsis zoo EmPRA

Electromagnetic inductor rau fluorescent teeb yus muaj los ntawm cov uas tsis muaj nqi, yooj yim siv thiab siab ntseeg.

Nyob rau hauv tas li ntawd, muaj cov drawbacks:

• pulsed lub teeb, ua rau lub qhov muag nkees;
• mus rau 15% yog poob hluav taws xob;
• suab nrov thaum lub sij hawm ntawm startup thiab thaum lub sij hawm kev lag luam;
• phem teeb yog pib ntawm ib tug tsawg kub;
• cov loj loj thiab hnyav;
• ntev community launch raj.

Feem ntau buzzing thiab flickering teeb tshwm sim thaum ib tug tsis ruaj tsis khov fais fab mov. Ballastniki tsim sib txawv suab nrov ntau ntau ntau. Yuav kom txo tau nws, koj muaj peev xwm xaiv ib tug haum qauv.

Teeb txawb thiab throttles yuav xaiv sib npaug zos rau txhua lwm yam rau lub hwj chim, los yog lub neej ntawm lub teeb yog significantly txo. Lawv feem ntau yog nkag nyob rau hauv cov khoom siv thiab hloov ballast ua tus ntaus ntawv nrog tib yam tsis.

Fluorescent teeb nrog EmPRA yog pheej yig thiab tsis tas yuav configure lawv.

Rau ballastnika cov yam ntxwv yog cov noj ntawm reactive lub hwj chim. Yuav kom txo tau txoj kev poob ntawm ib tug capacitor kev cob cog rua nyob rau hauv uas tig mus rau lub hwj huam mov.

hluav taws xob ballast

Tag nrho cov shortcomings ntawm lub electromagnetic throttle yuav tsum tau tshem tawm, thiab qhov hluav taws xob ballasts rau fluorescent teeb (ECG) yog tsim los pab raws li ib tug tshwm sim ntawm kev tshawb fawb. Lub tswvyim yog ib chav tsev xwb, generating pib thiab tswj kom lub combustion txheej txheem los ntawm txoj kev ua ib theem zuj zus predetermined ntawm voltage hloov. Txuas nws, koj muaj peev xwm siv cov lus qhia nkag nrog cov qauv.

Zawm caj pas yog rau fluorescent teeb hluav taws xob hom muaj zoo:

• tau instant pib los yog nrog tej kev ncua;
• tsis muaj ib tug pib;
• tsis muaj blinking;
• nce luminous efficiency;
• compactness thiab lightness ntawm tus dais;
• optimum kev khiav hauj lwm tej yam kev mob.

Hauv ballasts kim electromagnetic ntaus vim nyuab hluav taws xob circuitry uas muaj xws li cov ntxaij lim dej, lub hwj chim tshaj kho, lub ballast inverter. Nyob rau hauv ib co qauv, muab kev tiv thaiv los ntawm erroneous pib teeb tsis muaj qhov muag teev.

Nyob rau hauv neeg xyuas hais txog qhov yooj yim ntawm kev siv ntawm lub zog-txuag hluav taws xob ballasts LDS, uas yog ua ncaj qha mus rau hauv lub nyob rau pa txheem cartridges.

Yuav ua li cas khiav ib tug fluorescent teeb siv cov hluav taws xob ballast?

Thaum lub tshuab hluav taws xob ballast ntawm lub electrodes yog energized thiab lub mas ntawm cov cua kub. Ces lawv tau txais ib tug haib impulse mus rau lub teeb lub teeb. Nws yog tsim los ntawm tsim muaj ib qho oscillation Circuit Court muaj nyob rau hauv cov lus teb rau cov tawm. Nyob rau hauv no txoj kev, ib tug zoo-rhuab cathodes qhuav tag nrho cov mercury nyob rau hauv lub teeb, li ntawd, yog ib qho yooj yim mus pib lub teeb. Tom qab qhov tshwm sim ntawm resonance ntawm lub paug oscillation Circuit Court tam sim ntawd lawm thiab cov voltage dauv mus rau lub neeg ua hauj lwm.

Lub hauv paus ntsiab lus ntawm cov lag luam yog zoo li tus embodiment ntawm hluav taws xob ballast nrog ib tug electromagnetic throttle, raws li cov teeb pib high voltage, uas yog ces txo mus rau ib tug qhov nqi thiab tswj kom lub paug nyob rau hauv lub teeb.

tam sim no zaus nce mus txog 20-60 kHz, uas flickering yog ua tau, thiab cov efficiency yuav ntau dua. Lub tswv yim yog feem ntau muaj rau cov hloov lub electromagnetic txhawm chim rau hluav taws xob. Nws yog ib qho tseem ceeb hais tias lawv yog haum rau lub hwj chim. Lub Circuit Court muaj peev xwm tsim los instant pib nrog ib tug gradual nce nyob rau hauv brightness. Khaub thuas pib tsim xis, tab sis cov kev pab cuam lub neej ntawm lub teeb yuav tsawg npaum li cas.

Fluorescent teeb tsis muaj oob khab, throttle

LDR yuav muaj xws li, tsis muaj cumbersome throttle siv es tsis txhob ib tug yooj yim incandescent teeb nrog lub hwj chim. Nyob rau hauv no cov tswvyim, raws li ib tug oob khab yog tsis yuav tsum tau.

Cov kev twb kev txuas yog tsim los ntawm lub rectifier, nyob rau lub voltage yog ob npaug los ntawm txoj kev capacitors thiab ignites lub teeb tsis muaj cua sov rau cov cathodes. Pheej nrog LDS los ntawm theem neeg xyuas pib nrog incandescent, limiting tam sim no. Capacitors thiab diodes, rectifier choj yuav tsum tau xaiv nrog ib tug paj tau paj ntawm pub voltage. Thaum powered LDR hwj los ntawm ib tug rectifier nyob rau hauv ib tes nws yuav sai sai no pib yuav tsaus ntuj. Nyob rau hauv cov ntaub ntawv no, nws yog tsim nyog los hloov cov polarity ntawm lub hwj huam mov.

Siv cov fluorescent teeb tsis muaj ib tug throttle, uas yog siv es tsis txhob resistive load, muab ib tug tsis muaj zog brightness.

Yog hais tias es tsis txhob ntawm incandescent teeb teem caj pas, lub teeb yuav taws considerably muaj zog.

Kos throttle serviceability

Thaum lub LDR yog tsis zes, kev txhaum yog vim li cas cov lus dag nyob rau hauv lub thaiv, lub teeb, ib tug oob khab los yog caj pas. Tej yam yooj yim yog vim li cas qhia tau tester. Ua ntej koj yuav mus saib lub teeb zawm caj pas yog nruab hnub nrig multimeter, disconnect lub hwj chim thiab paug capacitors. Ces kws hloov yog ntsia tau rau hauv lub laaj xeem hom los yog qhov tsawg kawg nkaus txwv impedance ntsuam thiab txiav txim:

• lub sam xeeb ntawm cov kauj winding;
• qhov hluav taws xob kuj ntawm lub winding;
• interturn luv luv Circuit Court;
• breakage ntawm lub kauj winding.

Lub tswv yim yog caw mus saib lub throttle los ntawm txuas mus rau lub network los ntawm ib tug incandescent teeb. Winding luv luv Circuit Court thaum nws burns kaj thiab serviceable - dimly.

Thaum ib tug txhaum yog kuaj throttle yog yooj yim los hloov, raws li cov kev kho yuav ua tau ntau kim heev.

Feem ntau cov feem ntau nyob rau hauv lub tswvyim mus down oob khab. Mus xyuas nws efficiency cuag ib tug paub zoo qhov chaw kav mus. Yog hais tias lub teeb tau tsis cig, ces yog vim li cas no sib txawv.

Throttle kuj mus nrog ib tug ua hauj lwm lub teeb los ntawm txuas ob nyob ntawm tej los ntawm nws mus rau nws puag. Yog hais tias lub teeb teeb luj lug, nws txhais tau tias operable throttle.

xaus

Daig caj pas rau daylight teeb zoo nyob rau hauv cov kev taw qhia ntawm kev txhim kho kev ua tau zoo. Hauv pab kiag li lawm pib tshem solenoid. Nyob rau tib lub sij hawm tseem yuav tau thov cov laus qauv variants vim lawv simplicity thiab tus nqi qis. Nws yog tsim nyog los nkag siab nyob rau hauv ib tug ntau yam ntawm hom, thiab rau kev siv lawv kom kev cob cog rua.
