I-Transformer sisixhobo esisebenzisa umgaqo wokungenisa i-electromagnetic ukuguqula i-AC voltage. Izinto eziphambili zayo ziquka i-primary coil, i-secondary coil kunye ne-iron core.
Kwimisebenzi ye-elektroniki, unokubona isithunzi se-transformer rhoqo, eyona ixhaphakileyo isetyenziswa kumbane njenge-voltage yokuguqula, ukuzodwa.
Ngamafutshane, umlinganiselo wevolthi yeekhoyili eziphambili nezesibini ulingana nomlinganiselo wokujika kweekhoyili eziphambili nezesibini. Ke ngoko, ukuba ufuna ukukhupha iivolthi ezahlukeneyo, ungatshintsha umlinganiselo wokujika kweekhoyili.
Ngokweefrekshini ezahlukeneyo zokusebenza kweetransformers, ngokubanzi zinokwahlulwa zibe ziitransformers ezisebenzisa ifrequency ephantsi kunye neetransformers ezisebenzisa ifrequency ephezulu. Umzekelo, kubomi bemihla ngemihla, ifrequency yamandla alternating current yi-50Hz. Sibiza iitransformers ezisebenza kule frequency ngokuba ziitransformers ezisebenzisa ifrequency ephantsi; Ifrequency yokusebenza yetransformer esebenzisa ifrequency ephezulu inokufikelela kumashumi e-kHz ukuya kumakhulu e-kHz.
Umthamo we-transformer ephindaphindayo ephezulu umncinci kakhulu kunowe-transformer ephindaphindayo ephantsi enamandla afanayo okuphuma.
I-transformer yinxalenye enkulu kakhulu kwisekethe yamandla. Ukuba ufuna ukwenza ivolumu ibe ncinci ngelixa uqinisekisa amandla okukhupha, kufuneka usebenzise i-transformer ephindaphindayo. Ke ngoko, ii-transformer eziphindaphindayo zisetyenziswa ekutshintsheni izixhobo zamandla.
Umgaqo osebenzayo we-high frequency transformer kunye ne-low frequency transformer ziyafana, zombini ezisekelwe kumgaqo we-electromagnetic induction. Nangona kunjalo, ngokwezinto ezisetyenziswayo, "ii-cores" zazo zisebenzisa izinto ezahlukeneyo.
Umbindi wesinyithi we-transformer enee-frequency eziphantsi uhlala upakishwe ngamacwecwe esinyithi e-silicon amaninzi, ngelixa umbindi wesinyithi we-transformer enee-frequency eziphezulu wenziwe ngezinto zemagnethi ezisebenzisa i-frequency ephezulu (ezifana ne-ferrite). (Ke ngoko, umbindi wesinyithi we-transformer enee-frequency eziphezulu ubizwa ngokuba yi-magnetic core)
Kwisekethe yombane ye-DC ezinzileyo, i-transformer ekhawulezayo idlulisela isignali ye-sine wave.
Kwisekethe yombane etshintshayo, i-transformer etshintsha rhoqo idlulisela isignali yesikwere se-pulse etshintsha rhoqo.
Xa amandla elinganisiwe, umlinganiselo phakathi kwamandla okukhupha kunye namandla okufaka e-transformer ubizwa ngokuba kukusebenza kakuhle kwe-transformer. Xa amandla okukhupha e-transformer elingana namandla okufaka, ukusebenza kakuhle yi-100%. Enyanisweni, i-transformer enjalo ayikho, kuba ukulahleka kobhedu kunye nokulahleka kwesinyithi kukho, i-transformer iya kuba neelahleko ezithile.
Yintoni ukulahleka kobhedu?
Ngenxa yokuba ikhoyili yetransformer inokumelana okuthile, xa umsinga udlula kwikhoyili, inxalenye yamandla iya kuba bubushushu. Ngenxa yokuba ikhoyili yetransformer ibotshelelwe ngocingo lwekopolo, oku kulahleka kukwabizwa ngokuba yilahleko yekopolo.
Yintoni ukulahleka kwesinyithi?
Ukulahleka kwesinyithi kwe-transformer kubandakanya ikakhulu iinkalo ezimbini: ukulahleka kwe-hysteresis kunye nokulahleka komsinga we-eddy; ukulahleka kwe-hysteresis kubhekisa ekubeni xa umsinga otshintshanayo udlula kwi-coil, imigca yamandla emagnethi iya kuveliswa ukuze idlule kumsinga wesinyithi, kwaye iimolekyuli ezingaphakathi kumsinga wesinyithi ziya kukhuhlana ukuze zivelise ubushushu, ngaloo ndlela zidle inxalenye yamandla ombane; Ngenxa yokuba umgca wamandla emagnethi udlula kumsinga wesinyithi, umsinga wesinyithi uya kuvelisa nomsinga obangelwe yi-induced current. Ngenxa yokuba umsinga uyajikeleza, ukwabizwa ngokuba ngumsinga we-eddy, kwaye ukulahleka komsinga we-eddy kuya kusebenzisa amandla athile ombane.
