The zida ndi dera la nyali fulorosenti

Nyali fulorosenti (LL) ndi gwero kuwala kwaiye kumaliseche magetsi mu sing'anga wa mankhwala enaake nthunzi ndipo mpweya inert. Izi zikutipatsa wosaonekayo ultraviolet chiwalitsiro akuchita pa phosphor wosanjikiza TACHIMATA mkati botolo galasi. A dera lililonse wa fulorosenti nyali ballast ndi chipangizo ndi ballast mu atomu (EmPRA).

mafotokozedwe chipangizo ndi LL

Ambiri babu nyali nthawi zonse anali kuvundikira cylindrical, koma tsopano akhoza kukhala mu mawonekedwe a chithunzi zovuta. Malekezero a maelekitirodi ndi wokwera pa izo, amapanga zokhudzana ena mwauzimu nyali filament zopangidwa tungsten. Iwo soldered ku chokanikiza ili kunja, kumene voteji umagwiritsidwa ntchito.

Gasi conductive sing'anga mkati LL ali ndi kukana negative. Izo kumaonekera kuchepetsa wa voteji pakati maelekitirodi zikuwonjezera ndi ponso panopa zimene ziyenera okha. Chiwembu pophatikiza nyali fulorosenti limapangidwa ballastnik (kutsamwa), cholinga chachikulu cha zimene - chilengedwe lalikulu voteji zimachitika chifukwa poyatsira ake. Kuwonjezera izo m'gulu EmPRA sitata - kuwala nyale anaika mkati ndi maelekitirodi awiri mu inert m'mlengalenga mpweya. Mmodzi wa iwo anapanga bimetal. Mu boma koyamba ndi maelekitirodi lotseguka.

Mfundo zikugwira ntchito ya LL

The sitata dera la nyali fulorosenti ntchito motere.

1. Pa dera ndi mphamvu, koma choyamba kudzera LL panopa si chifukwa malo lalikulu kukana. Ndi mizere yozungulira cathode panopa akudutsa ndi likamatenthetsa iwo. Komanso, nawonso amaperekedwa ku sitata umene kotunga voteji ndi chokwanila unachokera mu chowala kumaliseche.
2. Pamene Kutentha sitata kulankhula mwa kupatsa panopa bimetallic mbale kutseka. Kenako, chitsulo wochititsa amakhala ndi kumaliseche ndi kutsazikana.
3. The elekitirodi bimetallic akamazizira pansi ndi kutsegula kukhudzana. Pamene kutsamwa izi zotuluka mkulu voteji zimachitika chifukwa chololera inductance, ndi LL ndi akayaka.
4. Icho chimapita kupyola nyale pano limene yafupika nthawi 2, monga voteji kudutsa inductor ukugwa. Sikokwanira Chisudzulo Chikuwononga kulankhula ndi sitata zotsalira pa nthawi kuyaka LL.

Chiwembu cha kulolerana kwa nyale luminescent awiri anaika mu luminaire wina, zimaphatikizapo kugwiritsa ntchito nawo kutsamwa wamba. N'zokhudza pa mndandanda, koma nyali anaika pa kufanana sitata wina.

The sangathe la nyali ndi pa vavu chachiwiri, ngati mmodzi wa iwo alephera.

Zofunika! Ndi nyali fulorosenti ayenera kugwiritsa ntchito masiwichi wapadera. Mu zipangizo zachuma kuyambira mafunde lalikulu, ndi kulankhula kungakhale yomata.

Fulumizitsa-free fulorosenti nyali kulolerana: chithunzithunzi

Ngakhale mtengo wotsika, ballasts mu atomu ndi zovuta. Anali chifukwa chilengedwe cha madera a pakompyuta a poyatsira (ECG).

Kachitidwe ndi LL ndi ballasts pakompyuta

Fulumizitsa-free likhale la nyali fulorosenti anapanga ndi amagetsi kulamulira wagawo, amene amapanga ndondomeko ya kusintha voteji pa poyatsira awo.

Ubwino wa dera e-pagalimoto:

• zotheka kuyambira kuchedwa nthawi iliyonse;
• Ife sitikusowa yaikulu mu atomu fulumizitsa ndi sitata;
• palibe ikulira ndi kuphethira zowala;
• mkulu wowala Mwachangu;
• lightness ndi compactness chipangizo;
• moyo wamkulu.

Modern ballasts pakompyuta ndi kukula yaying'ono ndi mowa mphamvu otsika. Iwo amatchedwa madalaivala, kuika mu m'munsi mwa nyali yaying'ono. Fulumizitsa-free kukhazikitsidwa kwa nyali fulorosenti amalola ntchito makatiriji ochiritsira muyezo.

Pakompyuta ballast dongosolo otembenuka ndi alternating voteji maukonde 220 kuti pafupipafupi mkulu. Choyamba LL maelekitirodi ndi usavutike, kenako kudyetsedwa ndi voteji mkulu. Pa dzuwa mkulu pafupipafupi ndi chinawonjezeka ndi kukulowa likuchotsedwa kwathunthu. Chiwembu likhale la nyali fulorosenti angapereke chiyambi ozizira kapena yosalala kuwonjezeka kuwala. Mbali yoyamba, ntchito ya moyo elekitirodi ndi kwambiri yafupika.

The voteji adakulabe mu dera la zamagetsi ndi zinalengedwa mwa dera la oscillation, zikubweretsa kumveka ndi nyale poyatsira. The Launch inadzachitika mosavuta kuposa mu chiwembu chakale ndi fulumizitsa mu atomu. Kenako, voteji amachepetsa pa mtengo wolakalakika wa posungira kumaliseche.

Voteji rectification imagwiridwa ndi diode mlatho, pambuyo umene ankawachotsera kufanana chikugwirizana capacitor C _1. Pambuyo kulumikiza kwa maukonde yomweyo mlandu capacitor C ₄ ndi chiswa dynistor. Amathamanga pa theka mlatho jenereta thiransifoma TR ₁ ndi transistors T ₁ ndi T _2. Pamene akuyesetsa 45-50 kHz pafupipafupi ndi kwaiye ntchito siriyo kumveka dera m'ma C _2, C _3, L _1, chikugwirizana ndi maelekitirodi, ndipo nyali uyatsa. Mu chiwembu uyu ali ndi kutsamwa, koma ndi miyeso ochepa, wakupatsani kuziyika izo mu m'munsi nyale.

Pakompyuta ballast ali basi zikusintha LL monga makhalidwe kusintha. Patapita kanthawi wofunikila ankavala kuwonjezeka nyale voteji kwa poyatsira. Mu chiwembu EmPRA mwachidule sadzakhala kuthaŵa, ndipo ballast pakompyuta zoti pansi kusintha makhalidwe chotero chimathandiza chipangizo ntchito zinthu zabwino.

Ubwino ballasts ano zamakono zili motere:

• zofewa chiyambi;
• chuma cha ntchito;
• kuteteza maelekitirodi;
• kupatulapo kukulowa;
• operability pa kutentha otsika;
• compactness;
• durability.

The kuipa ndi mtengo wapamwamba ndi zovuta dera poyatsira.

Ntchito ya multiplier voteji

njira limachititsa kuti monga mu atomu LL popanda ballast, koma makamaka ntchito kutalikitsa moyo wa nyale. Dera nyali fulorosenti yopsereza kunja zimawathandiza ntchito kwa nthawi yaitali, ngati mphamvu si upambana 20-40 Watts. Pankhaniyi filament ikhoza kukhala labwinobwino kapena lotengeka. Pa nthawi zonsezi, mfundo iliyonse filament m'pofunika yochepa dera.

Pambuyo kuthetsa ndi voteji ndi kawiri, ndipo nyali zounikira mpaka nthawi yomweyo. Capacitors C _1, C ₂ amasankhidwa kwa voteji opaleshoni ya 600 V. drawback wawo ndi chachikulu. The capacitors C _3, C ₄ wokwera pa Mica 1000 V.

LL sinafike kwa mwachindunji panopa magetsi. M'kupita kwa nthawi, Mercury amasonkhana pafupi mmodzi wa maelekitirodi, ndi kuwala kwa moto wa kufooka. Kubwezeretsa kusintha polarity kuchotseratu nyale. Ndi zotheka n'kuyamba kotero kuti si kuwombera.

Besstarternaya chiwembu cha kulolerana kwa nyale luminescent

Chiwembu sitata amafuna yaitali zochangamutsa nyale. Komanso, nthawi zina zofunika kusintha. Pa nkhani imeneyi, pali chiwembu wina ndi maelekitirodi mkangano kudzera yachiwiri akutsirizika wa thiransifoma ndi zomwe amachita ntchito ya ballast lapansi.

Pamene lophimba wapangidwa a nyali fulorosenti popanda sitata, iwo ayenera kukhala RS lakuti (kudya chiyambi). Nyali ndi Launch sitata sizigwira ntchito kuno bola maelekitirodi ake ndi mkangano, ndi mwauzimu mofulumira kutenthedwa.

Kodi kuyatsa nyali yopsereza?

Ngati mwauzimu mu dongosolo, LL akhoza akayaka popanda multiplier voteji, ntchito chiwembu mwachizolowezi EmPRA. Chiwembu chimathandiza zinaphatikizidwa nyali fulorosenti imasiyana kwangochepetsako pang'ono chabe poyerekeza ndi ochiritsira. Chifukwa chaichi, ndi sitata capacitor chikugwirizana mu mndandanda, ndi elekitirodi zikhomo ndi yochepa circuited. Pambuyo yaing'ono zosinthidwa nyale lidzakhalapo kwa kanthawi.

Pomaliza

Kulengedwa ndi dera la nyali fulorosenti zonse zilibwino kwa chuma, kuchepetsa kukula ndi kuchuluka moyo utumiki. Nkofunika masuku pamutu izo, kumvetsa zosiyanasiyana mitundu ya opangidwa ndi kudziwa njira kulumikiza.
