UCanwin yiNkampani yeNkampani yoTshintsho lwaMandla kunye noMvelisi woMbane woMbane
Ii-cores ze-transformer ezisetyenziswa ngokuqhelekileyo zenziwe ngamashiti ensimbi ye-silicon. I-silicon yensimbi luhlobo lwentsimbi eyenziwe nge-silicon (i-silicon ikwabizwa ngokuba yi-silicon), kwaye umxholo wayo we-silicon yi-0.8 ukuya kwi-4.8%. Undoqo wesinyithi we-transformer yenziwe ngentsimbi ye-silicon kuba intsimbi ye-silicon ngokwayo iyimathiriyeli yamagnetic enokungena ngamandla kozibuthe.
Siyazi ukuba i-transformer yangempela ihlala isebenza kwimeko ye-AC, kwaye ukulahlekelwa kwamandla akukhona nje ukuchasana kwekhoyili, kodwa nakwi-core core phantsi kwe-magnetization ye-current alternating. Ilahleko yamandla kumbindi wentsimbi idla ngokubizwa ngokuba yi "iron loss". Ukulahleka kwentsimbi kubangelwa zizizathu ezibini, enye "yi-hysteresis loss" kwaye enye "yi-eddy current loss".
Ukulahleka kwe-hysteresis yilahleko yentsimbi ebangelwa yi-hysteresis phenomenon ngexesha lenkqubo ye-magnetization ye-iron core. Ubungakanani bale lahleko bulingana nobukhulu bendawo evalelwe yi-hysteresis loop yezinto. I-hysteresis loop ye-silicon yensimbi incinci, kwaye ilahleko ye-hysteresis ye-iron core ye-transformer encinci, enokunciphisa kakhulu iqondo lokuvelisa ukushisa.
Kuba intsimbi yesilicon inezi nzuzo zingasentla, kutheni ungasebenzisi isiqwenga esipheleleyo se-silicon njengondoqo wentsimbi, kodwa uphinde uyiqhube ibe ziiflakes? Oku kungenxa yokuba i-chip core inokunciphisa olunye uhlobo lwelahleko yentsimbi - "ilahleko yangoku ye-eddy".
Xa i-transformer isebenza, kukho umbane otshintshileyo kwikhoyili, kwaye i-magnetic flux eyivelisayo ngokuqinisekileyo iyatshintshana. Olu tshintsho lutshintshayo lwemagnethi lubangela umsinga kumbindi wentsimbi. Umbane owenziweyo owenziwe kumbindi wentsimbi ujikeleza kwinqwelomoya ejonge kwicala lemagnethi, ke ibizwa ngokuba yi-eddy current.
Ilahleko yangoku ye-Eddy nayo ishushu ingundoqo. Ukuze kuncitshiswe ilahleko yangoku ye-eddy, i-iron core ye-transformer yenziwe ngamashiti ensimbi ye-silicon afakwe kwi-insulated ukusuka komnye nomnye, ukwenzela ukuba i-eddy yangoku idlule kwi-cross-section encinci kwi-loop emxinwa kunye nexesha elide ukwandisa ukuchasana. kwindlela yangoku eddy; ngexesha elifanayo, i-silicon kwi-silicon yensimbi yenza i-Resistivity yempahla yanda, ephinda isebenze ekunciphiseni imisinga eddy.
Kwisiseko sentsimbi ye-transformer, i-silicone sheet sheet yensimbi epholileyo enobunzima obuyi-0.35mm isetyenziswa ngokubanzi. Ngokobungakanani bentsimbi efunekayo, inqunyulwe ibe yincinci ende, ize igqitywe kwimilo "yemini" okanye "umlomo" imilo. Ukuthetha ngokwethiyori, ukuze kuncitshiswe i-eddi yangoku, ukuncipha kobunzima beshiti lensimbi yesilicon kunye nokuncipha kwephepha elidityanisiweyo, kokukhona isiphumo singcono. Oku akunciphisi ilahleko yangoku ye-eddy kunye nokunyuka kwamaqondo obushushu, kodwa ikwagcina izixhobo ezisetyenziselwa i-silicon sheet sheet.
Kodwa eneneni xa usenza i-silicon sheet iron core. Akunjalo kuphela kwizinto ezithandekayo ezikhankanywe ngasentla, kuba ukuveliswa kwentsimbi yentsimbi kuya kwandisa kakhulu iiyure zomntu kunye nokunciphisa i-cross-section esebenzayo yentsimbi yentsimbi. Ngoko ke, xa usebenzisa i-silicon sheet sheets ukwenza ii-cores ze-transformer, kufuneka siqhubeke kwimeko ethile, silinganise i-pros and cons, kwaye ukhethe ubukhulu obuhle kakhulu.
Iinguqu zenziwa ngokomgaqo wokungeniswa kwe-electromagnetic. Kukho amajiko-jiko amabini, ukujija okuphambili, kunye nokujika okwesibini, inxeba kumlenze ongundoqo ovaliweyo. Xa ujiko oluphambili lububuxoki kumbane wobonelelo lwamandla e-AC. Kukho umbane otshintshileyo kwiqela le-Rao yasekuqaleni, kwaye amandla amagnetic asekiwe, kwaye i-alternating main flux magnetic iveliswa kumbindi wentsimbi phantsi kwesenzo sesakhono samagnetic.
Kutheni le nto inokunyuswa, kwaye ihlawulwe? Emva koko kufuneka icaciswe ngumthetho kaLenz. I-magnetic flux eyenziwa yi-current induced isoloko ithintela utshintsho lwe-circular magnetic flux. Xa ukuqukuqela kwemagnethi kwasekuqaleni kusanda, ukuqukuqeka kwemagnethi okwenziwa ngumbane oyenyelweyo kuchasene nemagnethi yantlandlolo, oko kukuthi, eyesibini Ukuqukuqela kwemagnethi okuveliswe kukujija kuchasene neyona nto iphambili yemagnethi eveliswa ngumjikelo wokuqala. i-voltage eguqukayo esezantsi ibonakala kwi-winding yesibini. Ngoko ke, i-iron core inxalenye yesiphaluka semagnethi ye-transformer.
