Txhawm rau kom cov duab tshwm rau ntawm lub vijtsam kinescope thiab cov neeg saib kom txaus siab rau lawv cov kev pabcuam nyiam, nws yog qhov yuav tsum tau coj lub teeb hluav taws xob uas khiav ncig nws thaj chaw tag nrho. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub saib lossis TV, uas lub raj xa hluav taws xob cathode ua haujlwm ua cov khoom siv, yooj yim piav qhia siv cov piv txwv ntawm cov khoom siv dub thiab dawb.
Yog li, cov duab ntawm qhov screen yog tsim los ntawm ib qho taw tes, nrog rau kev khiav ntau pua kab. Peb pom tag nrho cov duab vim yog inertia ntawm lub cev ntawm peb lub zeem muag.
Dhau li ntawm qhov no, txhawm rau kom cov duab ua kom muaj zog, kev hloov ntawm cov thav duab kuj tseem tsim nyog. Cov kab hluav taws xob hluav taws xob khiav los ntawm kab los ntawm sab saum toj mus rau hauv qab thiab rov qab los dua vim tias nws tau tsav los ntawm cov hlau nplaum tsim los ntawm windings ntawm deflecting system. Yuav kom qhov no tshwm sim, koj yuav tsum tau hloov qhov tam sim no hauv nws nrog ib qho qauv.
Lub TV qub qub suav nrog ntau lub pob: cov khoom siv hluav taws xob, kab rov tav thiab ntsug scanning, xov tooj cua channel, chav tswj hwm, lub suab nrov qis thiab cov xim xim yog tias lub receiver yog xim. Lub ntsiab tseem ceeb ntawm kab rov tav scanning chav tsev yog kab rov tav transformer. Nyob rau hauv niaj hnub TVs, nws yog feem ntau ua ke nrog ib tug multiplierhluav taws xob. Nws lub hom phiaj yog kom tau txais sawtooth pulses ntawm hluav taws xob tam sim no, uas yog pub rau lub windings ntawm deflecting system. Lub voltage multiplier, mounted nyob rau hauv tib lub vaj tse raws li kab rov tav transformer, tsim ib tug siab, mus txog rau 27 kilovolts, accelerating voltage, uas ua kom lub acceleration ntawm electrons nyob rau hauv lawv lub zog ntawm lub screen npog coated nrog ib tug phosphor. Nws, nyob rau hauv lem, yog pub rau lub kinescope los ntawm ib tug high-voltage insulated input nrog ib tug thiaj li hu ua "pattern" uas tiv thaiv kev sib cuag los ntawm kev puas tsuaj ntawm rooj plaub.
Ib kab-scan transformer mounted ua ke nrog ib tug multiplier (TDKS) muaj ob peb windings uas tsim ntxiv tswj teeb liab. Cov no suav nrog kev ua kom pom tseeb thiab qhov loj ntawm qhov nrawm nrawm, nrog rau cov windings rau damping lub backswing ntawm lub nqaj, uas yuav tsum tsis txhob pom ntawm qhov screen.
Yog li, ob pab pawg ntawm windings ntawm deflecting system muab scanning ntawm raster vertically (ncej, CR) thiab kab rov tav (linear, SR). Yog li ntawd, nws cov duab yog ze heev rau lub duab plaub, tab sis tsis sib haum rau nws. Qhov kev sib txawv no yog vim qhov sib txawv ntawm qhov kev ncua deb uas cov electrons yuav tsum tau kov yeej ntawm lawv txoj kev mus rau lub npog ntsej muag. Qhov ze rau ntawm ntug ntawm lub vijtsam, qhov loj dua, thiab CRTs nrog cov ntxaij vab tshaus tiaj tus raug kev txom nyem los ntawm qhov tsis xws luag mus rau ntau dua li lawv cov "bulging" counterparts. Cov kab transformer, ua ke nrog cov multiplier thiab deflection system, yuav tsum tau ceev faj kev cai thiab tuning, tom qab uas lub distortion yuav tsawg heev.
Cov kev xav tau rau qhov zoo ntawm TDKS yog qhov siab heev, lub sijhawm ntawm kev ua haujlwm raug ntawm tag nrho cov neeg txais TV nyob ntawm nws. Kab transformers yog structurally tsim nyob rau hauv daim ntawv ntawm ib tug sib sau ua ke uas muaj ib tug compound thiab kho tsis tau, yog li ntawd tag nrho cov sab hauv kev sib cuag ntawm lub windings yuav tsum tau txhim khu kev qha.
Lub CP Node siv feem ntau ntawm lub zog siv los ntawm TV, mus txog ib nrab ntawm nws tag nrho.
Zoo li txhua yam khoom siv inductive, kab rov tav transformer muaj lub voj voog sib nqus uas ua haujlwm raws li lub hauv paus ntawm cov coils tau muab tso rau. Txhawm rau txo qhov loj me, nws yog ua los ntawm cov ferrite tshwj xeeb nrog cov hlau nplaum sib nqus.
Rau tag nrho cov laj thawj no, TDKS yog qhov khoom kim tshaj plaws ntawm kev hwm tom qab lub kinescope, qhov xav tau uas yuav tshwm sim thaum kho lub TV.
