I-transformer esetyenziswa ngokuqhelekileyo umbilinis ngokubanzi zenziwe ngamashiti ensimbi ye-silicon. I-silicon yensimbi luhlobo lwentsimbi equkethe i-silicon (i-silicon ikwabizwa ngokuba yi-silicon), kunye nomxholo wayo we-silicon ngu-0.8 ukuya kwi-4.8%. Silicon steel isetyenziswa njenge isinyithi Undoqo we-transformer kuba i-silicon intsimbi ngokwayo yinto enozibuthe ekwaziyo ukufikeleleka ngamandla. Kwikhoyili enikwe amandla, inokuvelisa amandla amakhulu okufakelwa kwamagnetic, ngaloo ndlela inciphisa umthamo we-transformer.

Siyazi ukuba i-transformer yangempela ihlala isebenza kwi-AC state, kunye namandla ukulahlekelwa akukhona kuphela ukuchasana kwekhoyili, kodwa nakwi isinyithi undoqo wemagnethi ngumsinga otshintshanayo. Amandla ukulahlekelwa kumbindi wentsimbi ngokuqhelekileyo kuthiwa “ilahleko yentsimbi”. Ukulahleka kwesinyithi kubangelwa zizizathu ezibini, enye “yi-hysteresis loss” kwaye enye “yi-eddy yangoku yokulahlekelwa”.

Ukulahleka kwe-Hysteresis yilahleko yentsimbi ebangelwa yi-hysteresis ngexesha lenkqubo ye-magnetization ye-iron core. Ubungakanani bale lahleko buhambelana nommandla ojikelezwe yi-hysteresis loop yezinto. I-hysteresis loop ye-silicon yensimbi incinci kwaye incinci, kwaye ilahleko ye-hysteresis ye-iron core ye-transformer encinci, enokunciphisa kakhulu isizukulwana sokushisa.

Kuba intsimbi yesilicon inezi nzuzo zingasentla, kutheni ungasebenzisi isiqwenga esipheleleyo se-silicon njengondoqo wentsimbi, kodwa uphinde uyiqhubele kwishiti?

Oku kungenxa yokuba i-sheet iron core inokunciphisa olunye uhlobo lwelahleko yentsimbi – “ilahleko yangoku ye-eddy”. Xa i-transformer isebenza, kukho i-alternating current kwi-coil, kwaye i-magnetic flux eyivelisayo ngokuqinisekileyo iyatshintshana. Olu tshintsho lutshintshayo lwemagnethi lubangela umsinga kumbindi. I-current induced eveliswa kwi-iron core ijikeleza kwi-plane perpendicular ukuya kwicala le-magnetic flux, ngoko ibizwa ngokuba yi-eddy current. Ilahleko yangoku ye-Eddy nayo ishushu ingundoqo. Ukuze kuncitshiswe ilahleko yangoku ye-eddy, umbindi wesinyithi we-transformer ufakwe kwi-silicon sheet sheets efakwe enye kwenye, ukuze i-eddy yangoku idlule kwicandelo elincinci lomnqamlezo kwisekethe emxinwa kunye nende, ukuze kwandiswe ukuxhathisa. kwendlela yangoku eddy; ngelo xesha, i-silicon kwintsimbi ye-silicon yenza Ukonyuka kwe-resistiveivity yezinto eziphathekayo kusebenza nokunciphisa imisinga eddy.

Njengombindi wentsimbi ye-transformer, iishiti ze-silicon eziqengqelekayo ezinobunzima obuyi-0.35 mm zikhethwa ngokubanzi. Ngokobungakanani bentsimbi efunekayo, inqunyulwe ibe ngamaqhezu amade, kwaye emva koko ihlanganiswe “kwimini” okanye “umlomo” imilo. Ukuthetha ngokwethiyori, ukuze kuncitshiswe i-eddy yangoku, ukuncipha kobukhulu beshiti lensimbi yesilicon kunye nokucutha imicu edityanisiweyo, kokukhona isiphumo singcono. Oku akunciphisi ilahleko yangoku ye-eddy kunye nokunyuka kwamaqondo obushushu, kodwa ikwagcina izinto ezisetyenziselwa i-silicon sheet sheet. Kodwa eneneni xa usenza i-silicon steel sheet core. Hayi nje ukuqala kwizinto ezithandekayo ezikhankanywe ngasentla, kuba ukwenza i-iron core ngaloo ndlela kuya kwandisa kakhulu iiyure zomntu kunye nokunciphisa i-cross-section ye-iron core. Ngoko ke, xa usebenzisa i-silicon sheet sheets ukwenza ii-cores ze-transformer, kuyimfuneko ukuba uqhubele phambili kwimeko ethile, ulinganise i-pros and cons, kwaye ukhethe ubungakanani obuhle kakhulu.
