Yog vim li cas xws li ib kim kab transformer
Yuav kom nyob rau CRT duab yog nyob rau qhov kev tshuaj ntsuam, thiab cov neeg tuaj saib yog tau txaus siab rau koj nyiam broadcasts, yuav tsum muab xa mus rau lub electron nqaj, looped nws tag nrho cheeb tsam. Lub hauv paus ntsiab lus ntawm cov lag luam ntawm tus saib los yog tus TV, nyob rau hauv uas ib tug zaub lub caij yog ib tug cathode txoj sab ci raj, yog yooj yim los qhia cov piv txwv ntawm ib tug dub thiab dawb kiag li lawm.
Yog li, cov duab ntawm qhov screen yog tsim los ntawm ib tug taw tes, nrog ib tug loj ntawm sau nyob ib ncig ntawm pua pua ntawm cov kab. Zuag qhia tag nrho daim duab peb yuav pom vim hais tias ntawm lub inertia ntawm peb lub cev.
Nyob rau hauv tas li ntawd, cov duab yuav tsum tau dynamic, thiab yuav tsum tau ib tug hloov ntawm cov neeg ua. Lub electron nqaj sau kab los ntawm kab los ntawm sab saum toj mus rau nram qab thiab rov qab dua vim hais tias nws yog tsav los ntawm lub magnetic teb generated los ntawm cov coils ntawm lub deflection system. Yuav kom qhov no yog li ntawd, nws yog tsim nyog los hloov nyob rau hauv tam sim no nrog ib tug tej regularity.
Classical TV Circuit Court muaj xws li ntau yam: hwj chim kab thiab ncej PP, xov tooj cua channel, tswj tsev, hwj chim tsawg zaus chrominance module yog ib cov xim receiver. Cov ntsiab keeb ntawm cov kab rov tav PP kab chav tsev yog ib tug transformer. Nyob rau hauv niaj hnub TVs nws yog feem ntau nrog rau ib tug voltage d. Nws lub hom phiaj - los muab sawtooth pulses ntawm hluav taws xob tam sim no, uas yog txhab khoom mus rau deflection kauj system. Multiplier voltage, mounted nyob rau hauv tib lub tsev nyob raws li txoj kab transformer, ua ib tug siab, mus txog 27 kilovolts accelerating voltage uas muab acceleration ntawm electrons nyob rau hauv lawv lub zog mus rau lub screen daim npog qhov ncauj, lub coated phosphor. Nws, nyob rau hauv lem, pub rau cov duab raj los ntawm txoj kev high-voltage insulated nkag mus rau hauv lub thiaj li hu ua "blotch" tiv thaiv cov kev sib cuag los ntawm lub neej puas lub vaj tse.
Transformer kab rov tav mounted ua ke mus ib d (TDKS) muaj ib tug xov tooj ntawm windings txoj kev ntxiv tswj Pib ntsais koj teeb. Cov no muaj xws adjustable kom pom tseeb thiab qhov ntau ntawm cov acceleration voltage, thiab kauj blanking blanking lub screen uas yuav tsum tsis txhob yuav pom.
Yog li, ob pab neeg ntawm windings ntawm lub deflecting system muab ib tug raster luam theej duab mas (HR, CR) thiab horizontally (kab rov tav, CP). Raws li ib tug tshwm sim ntawm nws txoj kev zoo yog heev ze rau lub square, tab sis nws tsis heev phim nws. Qhov no sib txawv yog tshwm sim los ntawm qhov sib txawv nyob rau hauv deb uas electrons tau kov yeej nyob rau txoj kev mus rau lub npog qhov ncauj. Cov los ze zog mus rau lub ntug ntawm lub screen, li ntawd, nws yog ntau, thiab CRT tiaj screen raug kev txom nyem los ntawm no kho raws mus rau ib tug ntau dua twg lawv "mas" counterparts. Kab transformer nyob rau hauv nrog ib tug d thiab lub deflection system yog ib tug ua tib zoo tswj thiab hloov khoom, tom qab uas lub distortion ua lub yam tsawg kawg nkaus.
TDKS mus rau qhov zoo yuav tsum yog heev siab heev, lub caij ntawm yog lub lag luam ntawm tag nrho cov TV receiver nyob ntawm nws. Voltage transformers yog lub tsev nyob rau hauv daim ntawv ntawm ib tug potted los ua ke thiab yuav kho tsis tau, yog li ntawd tag nrho cov sab hauv cov neeg ntawm lub windings yuav tsum heev txhim khu kev qha.
CP ntawm kov feem ntau ntawm lub zog noj los ntawm lub TV mus rau ib nrab ntawm tag nrho cov nws tus nqi.
Zoo li tej inductive ntaus ntawv, kab transformer muaj ib tug sib nqus cov tub ntxhais uas ua hauj lwm pab raws li cov tub ntxhais uas lub coils yog muab tso. Nyob rau hauv thiaj li yuav txo qhov luaj li cas, nws yog tsim los ntawm tshwj xeeb ferrite uas muaj magnetic conductivity.
Rau tag nrho cov yog vim li cas TDKS - lub feem ntau kim hloov yawm tom qab CRT, qhov yuav tsum tau rau cov uas tej zaum yuav tshwm sim thaum uas lub TV kho.
