Kungani kunokungqubuzana okunjalo ezibizayo umugqa transformer i

Ukuze isithombe CRT kuyinto esikrinini, futhi izilaleli ngakwazi ukujabulela ukusakaza kwakho okuthandayo, kufanele zithunyelwe ugongolo electron, looped yonke indawo yayo. Umgomo we operation ye qapha noma i-TV, lapho isici isibonisi a cathode ray tube, kulula ukwethula ngesibonelo amadivayisi omnyama nomhlophe.

Ngakho, kwakheka isithombe esikrinini is by iphuzu elilodwa nje, nge imvamisa eliphezulu lokugijima emhlabeni amakhulu imigqa. Sitfombe singabona ngenxa inertia imizimba yethu.

Ngaphezu kwalokho, isithombe ku-dynamic kushintsha, futhi kudinga ushintsho kwabasebenzi. Ugongolo electron siphela umugca ngemugca kusukela phezulu kuya phansi kanye emuva ngoba eshukunyiswa amandla kazibuthe eyenziwe ohlobo kohlelo kuka. Ukuze lokhu kunjalo, kubalulekile ukuba ukushintsha e zamanje nge njalo ezithile.

Classical TV isifunda sihlanganisa iSifundazwe izingxenye ezihlukahlukene: amandla umugqa futhi Uhlaka ukuskena, isiteshi somsakazo, control unit, amandla nobuningi ongaphakeme chrominance module uma isamukeli umbala. Isici esiyinhloko we ovundlile ukuskena umugqa Phiko a transformer. Ngo-TV yesimanje ngokuvamile kuhlangene Okuphindaphinda voltage. Inhloso yayo - ukuhlinzeka pulses ezishibilikayo nezicijile kagesi, okuyinto ayanikezelwa ohlelweni ikhoyili kuka. voltage Okuphidaphindayo, aboshelwe izindlu efanayo transformer umugqa, kuveza okusezingeni eliphezulu, kuze 27 kilovolts kuyashesha voltage enikeza ukusheshisa electron ukunyakaza kwabo imaskhi isikrini, phosphor camera. It yena, wapha kuya tube isithombe esebenzisa ephezulu voltage ngci ngokufaka okuthiwa "ibala" ivikela contact kusukela ukuhlukaniswa izindlu.

Transformer ovundlile ukukhwezwa ndawonye a wokuphindaphinda (TDKS) enezinto eziningi Windings obumba amasignali control ezengeziwe. Lezi zihlanganisa focus adjustable nokubaluleka voltage ukushesha, futhi ikhoyili iyathula iyathula esibukweni okumele zingabonakali.

Ngakho, amaqembu amabili Windings kohlelo deflecting ihlinzeka raster scan zibheka (HR, CR) kanye nendawo (ovundlile, CP). Ngenxa ezakheke liseduze kakhulu isikwele, kodwa akusho ngempela oyosisiza ukuba sibhekane nakho. Lokhu ukuphambuka kubangelwa umehluko ibanga ukuthi electron kudingeke siyeke endleleni eya imaskhi. I eduze onqenqemeni kwesikrini, ngakho-ke ngaphezu kwalokho, futhi CRT flat screen uhlushwa le nkinga ngokwezinga elikhulu ukwedlula nozakwabo "abavelele". Line transformer ihambisana Okuphindaphinda futhi uhlelo kuka Uyi control ngokucophelela futhi ukulungiswa into, okwathi ngemva kwalokho ukuhlanekezela iba ubuncane.

TDKS izidingo izinga ephakeme kakhulu, isikhathi operation efanele yonke ithelevishini umamukeli sincike kuyo. Voltage transformers zakhiwa ngendlela umhlangano ezimbizeni futhi ayikwazi ukulungiswa, ukuze bonke oxhumana nabo yangaphakathi phakathi Windings kumelwe abe enokwethenjelwa kakhulu.

CP node ibusa iningi amandla sokudliwa TV Ingxenye yayo yonke ukudayiswa kwayo ngemali eyifanele.

Njenganoma yimuphi idivayisi exhasa, umugqa transformer has a core enozibuthe ukhonza njengoba core lapho ohlobo ifakwa. Ukuze kuncishiswe ubukhulu, esenziwe ferrite ekhethekile nge high conductivity kazibuthe.

Ngoba konke lokhu izizathu TDKS - eqolo esikhundleni udumo ngemva CRT, isidingo okuyinto engase iphakame lapho TV lalungiswa.
