Kho ntawm lub zog-saving qhov muag teev nyob thiaj li yuav cawm tau

Nyob rau hauv xyoo tsis ntev los, ntau thiab ntau sib muaj yog ib tug kev hloov ntawm zoo tib yam qhov muag teeb nrog lub zog txuag teeb. Lub hauv paus rau lawv yog me me-sized fluorescent teeb, uas nws ua hauj lwm yog tswj los ntawm ib tug hluav taws xob triggering regulating ntaus ntawv (electronic ballast, hluav taws xob ballast). Kim branded teeb muaj ib tug mos mos pib thiab khiav ntev npaum li cas, suab nyob rau hauv lub lav lub sij hawm. Tiam sis qhov ntau kim kev xaiv, raws li zoo raws li imitations ntawm nrov hom tsis nrhiav pov thawj entrusted rau lawv cia siab rau long-term lub lag luam thiab yog yooj yim puas. Piv rau pa incandescent qhov muag nqi ntawm hloov lawv "housekeepers", raws li zoo raws li fluorescent teeb yog ntau dua, ces tus kho ntawm fluorescent teeb, raws li zoo raws li lub zog-txuag kev xaiv, txhaum nyob rau hauv thiaj li yuav cawm tau. Tom qab lub restoration ntawm lawv noj qab haus huv yuav tsum yuav tshiab teeb ruaj.

Cov uas keev ua tsis ua hauj lwm yog breakage ntawm filament yarns los yog malfunction ntawm tshuav nyiaj li cas vim tus rhuav tshem ntawm lub resonance capacitor los yog transistor. Kho ntawm lub zog-txuag teeb no tsuas tau nyob rau hauv cov ntaub ntawv ntawm ib tug ballast txhaum. Teeb txawb nrog burnt filaments tsis tas yuav muab pov tseg. Lawv yuav tsum tau siv los hloov cov puas ballast lwm yaj, yog hais tias tus xov lawv yog nyob rau hauv kev ua hauj lwm kev txiav txim. Txawm li cas los, nyob rau hauv tej zaum nws yog tau mus kho cov burnt kauv, kaw nws resistor muaj hwj huam (txog 25 W, 10 ohms) thiab tshem tawm cov shunt diode no kauv, yog hais tias nws tshwm sim. Tab sis feem ntau ntawm cov kev kho yuav tsum tau hloov ntawm lub zog-txuag teeb hluav taws xob ballast. Nws yuav tsum tau hloov yog kiag li los yog, thaum lub kev txawj, koj yuav tau sim hloov tsuas qhov chaw uas tsis.

Yog vim li cas lub tso zis ntau zog txuag teeb tsis ua hauj lwm yuav ua tau ib qho nyuaj hom ntawm nws cov lag luam - nyob rau ntawm qhov chaw ntawm lub electrode kub nce mus txog 60 degrees vim tsis muaj chaw dim pa (nyob rau hauv lub teeb hau muaj qhov). Overheating ua rau sagging thiab breakage ntawm lub filaments thiab cov tsis ua hauj lwm ntawm lub ballast ntsiab. Kho ntawm lub zog txuag teeb tej zaum yuav tsim nyog yog hais tias muaj yog yam ntxwv tsis xws luag nyob rau hauv lub rooj sib txoos ntawd los yog txhob txwm nyob rau hauv thiaj li yuav cawm tau. Tshwj xeeb tshaj yog no txoj kev txhaum Suav teeb. Nyob rau hauv thiaj li tsis mus khiav rau hauv xws li gore- "cov neeg tu vajtse", koj yuav tau mus yuav cov khoom uas nto moo manufacturers. Piv txwv li, qhov yuav tsum tau nqa tawm kho ntawm lub zog-txuag teeb "Kosmos», «Volta» thiab lwm yam zoo-paub ntxhab nyob rau hauv kev xyaum muaj ntau tshaj muaj los kho lawv Suav counterparts.

Dismantling ntawm lub zog txuag teeb tsis yog tshwj xeeb tsis yooj yim, Txawm li cas los, yuav ua li cas nws ua tib zoo thiaj li tsis mus ua txhaum lub hwj, nws yog heev yooj yim. Peb yuav tsum tsis txhob hnov qab tias hauv lub hwj muaj mercury vapor yog txaus ntshai rau kev kho mob. Qhib lub casing ntawm lub tshuab hluav taws xob ballast yuav ua tau ib tug ntse yam khoom (ib tug nqaim ntswj ntsia hlau), rau cov uas nws yog tsim nyog los daws qhov latch txuas lub yas qhov chaw ntawm lub cev. Ces koj yuav tau disconnect tus hlau qwj tso zis los ntawm cov hluav taws xob Circuit Court. Nws tseem hauv pawg, ob conductors kev cob cog rua rau hais tias ib feem ntawm lub cev, uas muaj peev xwm mount lub plinth. Tom ntej no, xyuas seb lub filament lawm ntawm xab tus kuj nrog ib tug ohmmeter. Yog hais tias infinite kuj qhia qhov ntau ntawm cov xov yog lawm. Nyob rau hauv cov ntaub ntawv no, raws li twb tau hais, lub hwj yog tsis muaj ntaub ntawv. Cov feem ntau yooj yim hluav taws xob Cheebtsam ntawm lub converter - capacitors C5, C4, C3, lawv yuav tsis thaum overload. Muaj mob thaum tsis ua hauj lwm los PTC los yog ib tug tsis tshua muaj kuj resistor R1, nws yog tsim nyog los them tus utmost xim rau kho ntawm lub zog-txuag teeb nrog ballast. Nws ua rau kev nkag siab rau tshawb xyuas thiab active Cheebtsam - transistors VT, diodes VD1-VD4 rectifier choj.

Ceeb toom! Soj ntsuam cov kev cai ntawm hluav taws xob kev nyab xeeb thiab tsis txhob lees paub kho ntawm lub zog-saving lam, tsis muaj kev txawj ntse ntawm kev ua hauj lwm nrog lub hwj chim cov cuab yeej.
