Isiguquli sisixhobo esisebenzisa umgaqo wokungeniswa kwe-electromagnetic ukuguqula amandla ombane e-AC.Amacandelo ayo aphambili abandakanya ikhoyili ephambili, icoil yesibini kunye nentsimbi yentsimbi.
Kwi-electronic professional, unako ukubona rhoqo isithunzi se-transformer, eyona nto ixhaphakileyo isetyenziselwa ukunikezelwa kwamandla njenge-voltage yokuguqula, ukuhlukaniswa.
Ngamafutshane, i-voltage ratio ye-coil yokuqala kunye neyesibini ilingana nomlinganiselo wokujika we-coil yokuqala kunye neyesibini.Ke ngoko, ukuba ufuna ukukhupha ii-voltages ezahlukeneyo, unokutshintsha umlinganiselo wokujika kweekhoyili.
Ngokutsho kwee-frequencies ezahlukeneyo zokusebenza kwee-transformers, ngokubanzi ziyakwazi ukwahlula zibe ziguquli eziphantsi kunye neziguquli eziphezulu.Ngokomzekelo, kubomi bemihla ngemihla, ukuphindaphinda kwamandla okutshintshana ngokuphindaphindiweyo ngu-50Hz.Sibiza ii-transformers ezisebenza kule frequency low-frequency transformers;I-frequency yokusebenza ye-high-frequency transformer inokufikelela kumashumi e-kHz ukuya kumakhulu e-kHz.
Umthamo we-high-frequency transformer incinci kakhulu kuneyo ye-low-frequency transformer enegunya elifanayo lokuphuma
I-transformer yinxalenye enkulu kwisekethe yamandla.Ukuba ufuna ukwenza ivolumu encinci ngelixa uqinisekisa amandla aphumayo, kufuneka usebenzise i-high-frequency transformer.Ke ngoko, ii-high-frequency transformers zisetyenziswa ekutshintsheni izixhobo zombane.
Umgaqo osebenzayo we-high frequency transformer kunye ne-low frequency transformer iyafana, zombini ezo zisekelwe kumgaqo wokufakelwa kwe-electromagnetic induction.Nangona kunjalo, ngokwezinto eziphathekayo, "ii-cores" zabo zisebenzisa izinto ezahlukeneyo.
Ingundoqo yentsimbi ye-low-frequency transformer ngokubanzi ifakwe kwi-silicone sheet sheets ezininzi, ngelixa i-iron core ye-high-frequency transformer yenziwe ngezinto eziphathekayo ezinombane (ezifana ne-ferrite).(Ke ngoko, umbindi wentsimbi we-high-frequency transformer ubizwa ngokuba ngundoqo wemagnethi)
Kwisekethe yobonelelo lwamandla ombane ozinzile kwiDC, isiguquli esinesantya esisezantsi sihambisa isiginali ye-sine wave.
Ekutshintsheni unikezelo lwamandla esekethe, i-high-frequency transformer ihambisa i-high-frequency pulse signal wave square.
Kumandla alinganisiweyo, umlinganiselo phakathi kwamandla okuvelisa kunye negunya lokufaka i-transformer libizwa ngokuba yimpumelelo ye-transformer.Xa amandla okuphuma kwe-transformer alingana namandla okufaka, ukusebenza kakuhle ngu-100%.Enyanisweni, i-transformer enjalo ayikho, kuba ukulahleka kobhedu kunye nokulahlekelwa kwentsimbi kukho, i-transformer iya kuba neelahleko ezithile.
Yintoni ilahleko yobhedu?
Ngenxa yokuba i-coil ye-transformer inokuchasana okuthile, xa ikhoyo ngoku idlula kwikhoyili, inxalenye yamandla iya kuba bubushushu.Ngenxa yokuba ikhoyili ye-transformer ilimala ngocingo lobhedu, le lahleko ikwabizwa ngokuba yilahleko yobhedu.
Yintoni ilahleko yentsimbi?
Ilahleko yentsimbi ye-transformer ikakhulu ibandakanya imiba emibini: ukulahleka kwe-hysteresis kunye nokulahleka kwangoku kwe-eddy;Ilahleko ye-Hysteresis ibhekisela kwinto yokuba xa i-alternating current idlula kwi-coil, imigca yemagnethi yamandla iya kuveliswa ukuba idlule kwi-core yentsimbi, kwaye iimolekyuli ezingaphakathi kwintsimbi yentsimbi ziya kukhuhla omnye komnye ukuvelisa ubushushu, ngaloo ndlela zidla inxalenye yamandla ombane;Ngenxa yokuba umgca wemagnethi wamandla udlula kumbindi wentsimbi, umbindi wentsimbi nawo uya kuvelisa i-induced current.Ngenxa yokuba umsinga uyajikeleza, ukwabizwa ngokuba yi-eddy current, kwaye ilahleko yangoku ye-eddy iya kusebenzisa amandla ombane athile.
