N'chifukwa chiyani mtengo mzere thiransifoma

Kuti pa CRT chithunzi pa zenera, ndi omvera anali ndi mwayi wokhala wailesi mumaikonda kuti abwelele kwa elekitironi mtengo, looped malo ake lonse. Mfundo ntchito ya polojekiti kapena TV, imene amafotokozera amasonyeza ndi cathode ray chubu, ndi kosavuta kuti mupereke chitsanzo cha zipangizo utoto.

Choncho, fano pa zenera aumbike mwa mfundo imodzi, ndi pafupipafupi mkulu wa akuthamanga kuzungulira mazana a mizere. Chithunzithunzi chonse ife tikhoza kuwona chifukwa cha inertia ya matupi athu.

Komanso, fano kukhala wochitachita, ndipo amafuna kusintha kwa ogwira. The elekitironi mtengo akuthamanga mzere ndi mzere kuchokera pamwamba mpaka pansi ndi kachiwiri chifukwa lotengeka ndi maginito kwaiye ndi coils a dongosolo kuchimwa. Kuti zili choncho, m'pofunika kusintha panopa ndi zonse zina.

Chakale TV dera zikuphatikizapo zosiyanasiyana zigawo zikuluzikulu: mphamvu mzere ndi chimango chindodo, wailesi njira, wagawo ulamuliro, mphamvu otsika pafupipafupi chrominance gawo ngati mtundu wolandila. The mbali yaikulu ya yopingasa chindodo mzere unit ndi thiransifoma. Mu ma TV masiku ano kaŵirikaŵiri pamodzi ndi multiplier voteji. cholinga chake - kupereka nyemba sawtooth wa magetsi, amene amaperekedwa kwa dongosolo kuchimwa koyilo. Multiplier voteji, wokwera pa nyumba mofanana mzere thiransifoma, umabala mkulu, mpaka 27 kilovolts mofulumira voteji amene amapereka mathamangitsidwe wa ma elekitironi mu gulu lawo kwa nsalu yotchinga chigoba, ndi lokutidwa phosphor. Izo, nawonso, kudyetsedwa cipangizo chubu mwa mkulu-voteji amalimata kulowa otchedwa "chikanga" kuteteza kukhudzana kwa kuwonongedwa kwa nyumba ya.

Thiransifoma yopingasa wokwera pamodzi ndi multiplier (TDKS) angapo a windings kupanga zina ulamuliro chizindikiro. Zikuphatikizapo cholinga chosinthika ndi kufunika kwa mathamangitsidwe voteji, ndi koyilo blanking blanking chophimba amene sayenera kuwoneka.

Choncho magulu awiri a windings wa dongosolo deflecting imapereka raster aone vertically (HR, Kr) ndi horizontally (yopingasa, CP). Chifukwa cha mawonekedwe ake ali pafupi kwambiri lalikulu, koma zilibe ndithu mogwirizana. zopatuka izi chifukwa cha kusiyana pa mtunda ma elekitironi kugonjetsa pa njira amabisa. The kwambiri m'mphepete mwa zenera, kotero, ndipo CRT lathyathyathya chophimba amadwala chilema izi Pamlingo kuposa omwe ankasonyeza "otchuka". Mzere thiransifoma molumikizana ndi multiplier ndi dongosolo kuchimwa ndi ulamuliro kusamala ndi kusintha chinthu, kenako kupotozedwa amakhala osachepera.

TDKS amafuna khalidwe ndi lalitali kwambiri, nthawi ya opaleshoni molondola za lonse TV wolandila ukudalira pa izo. Voteji tiransifoma pomanga mu mawonekedwe a msonkhano potted ndipo sangathe anakonza, kotero kuti kulankhula mkati pakati windings ayenera kukhala odalirika kwambiri.

CP mfundo amadya kwambiri wa mphamvu ankadya ndi TV kwa theka la mtengo wake onse.

Ngati chipangizo china chilichonse inductive, mzere thiransifoma ali pakati maginito kuti akutumikira monga pachimake pa zomwe coils ndi kuika. Pofuna kuchepetsa kukula, chopangidwa kuchokera ferrite wapadera ndi mkulu maginito madutsidwe.

Pazifukwa izi TDKS - kwambiri mtengo m'malo ulemu pambuyo CRT, kufunika zomwe zingabuke pamene TV anakonza.
