Iziguquli ngamacandelo abalulekileyo kwinkqubo yokusasazwa kombane kunye nenkqubo yothumelo, esebenza ekunyuseni okanye ukuthoba amandla ombane njengoko kufuneka ukuqinisekisa unikezelo lombane olusebenzayo noluthembekileyo. Embindini wayo yonke i-transformer kukho undoqo we-transformer, odlala indima ebalulekileyo ekusebenzeni kwesixhobo. Ukuqonda ukwakhiwa kwee-cores ze-transformer kubalulekile ekuphuculeni ukusebenza kwazo kunye nokuthembeka. Kweli nqaku, siza kuhlolisisa izinto kunye neenkqubo zokuvelisa ezibandakanyekayo kulwakhiwo olungundoqo lwe-transformer, ukubonelela ngolwazi oluxabisekileyo lweenjineli, abavelisi, kunye nabani na onomdla kwiteknoloji emva kweenguqu.

Iziseko zeTransformer Cores

Iinqununu zeTransformer zingundoqo ekusebenzeni kweenguqu, zisebenza njengendlela yamagnetic evumela ukuhanjiswa kwamandla phakathi kwe-winding primary and secondary windings. Ezi cores ngokwesiqhelo zakhiwa ngamashiti entsimbi yombane elaminethiweyo, adityaniswe kunye ukuze enze ulwakhiwo oluqinileyo, kodwa olungena imagnethi. Umsebenzi oyintloko we-core kukubonelela ngendlela ephantsi yokungafuni ukuguquguquka kwamagnetic eyenziwa yi-primary winding, ukuqinisekisa ukuhanjiswa kwamandla okusebenzayo kwi-winding yesibini. Ngokwenyani, undoqo usebenza njengekhonkco lamagnetic phakathi kweendlela eziphambili kunye nesekondari, okwenza ukuguqulwa kwamandla ombane ukusuka kwinqanaba lombane ukuya kwelinye.

Ukukhethwa kwezinto eziphathekayo kungundoqo we-transformer kubalulekile, njengoko kuchaphazela ngokuthe ngqo ukusebenza kwesixhobo, ilahleko, kunye nokusebenza ngokubanzi. Kwicandelo elilandelayo, siza kuphonononga izinto ezahlukeneyo ezisetyenziswa kulwakhiwo olungundoqo lwe-transformer kunye neempawu zazo.

Izinto ezisetyenziswa kwiTransformer Cores

Eyona nto isetyenziswa ngokuqhelekileyo kwii-cores ze-transformer yintsimbi yombane, eyenzelwe ngokukodwa izicelo ezifuna amandla ombane aphezulu kunye nelahleko ephantsi. Insimbi yombane ifumaneka kwiindidi ezimbini eziphambili: i-grain-oriented (GO) kunye ne-non-oriented (NGO). I-GO yensimbi yombane iveliswa ngokusebenzisa inkqubo ekhethekileyo yokuvelisa elungelelanisa i-crystal grains kwi-steel kwicala elithile, okubangelwa iimpawu eziphezulu zamagnetic kuloo ndlela. Oku kuyenza ifaneleke ngokukodwa kwiziguquli ezikumgangatho ophezulu, ezifana nezo zisetyenziswa ekudalweni nasekuhanjisweni kwamandla.

Ngakolunye uhlangothi, insimbi yombane ye-NGO iveliswa ngaphandle kokukhetha okuziinkozo okukhethiweyo, okwenza ukuba ifaneleke ngakumbi kwizicelo apho i-magnetic flux iyahluka kwicala, njengakwi-transformers yokusabalalisa. Zombini ezi ntlobo zentsimbi yombane zibonelela ngokungena kwemagnethi ephezulu kunye nelahleko ephantsi, izenza zilungele ulwakhiwo olungundoqo lwe-transformer.

Ukongeza kwintsimbi yombane, ezinye izinto ezifana nentsimbi ye-amorphous kunye ne-ferrite nazo zisetyenziswa kwiintlobo ezithile ze-transformers. I-amorphous metal cores yenziwe kwi-alloy non-crystalline alloy, ebonisa ilahleko engaphantsi kwengundoqo kunentsimbi yendabuko yombane. Oku kubenza babe lolona khetho lubalaseleyo kwii-transformers eziphezulu, nangona ixabiso eliphezulu. Ii-Ferrite cores, kwelinye icala, ziqhele ukusetyenziswa kwi-high-frequency kunye ne-low-power transformers ngenxa yeempawu zazo ezithandekayo zemagneti kumaza aphezulu.

Ukukhethwa kwezinto eziphambili kuxhomekeke kwizinto ezahlukeneyo ezifana nesicelo esijoliswe kwi-transformer, iimfuno zokusebenza kakuhle, kunye nokuqwalaselwa kweendleko. Kwicandelo elilandelayo, siza kuphonononga iinkqubo zokuvelisa ezibandakanyekayo kulwakhiwo olungundoqo lwe-transformer, oludlala indima ebalulekileyo ekubumbeni iimpawu zokugqibela zondoqo.

Iinkqubo zokuVelisa iiCore Transformer

Ukwenziwa kwee-cores ze-transformer kubandakanya iinkqubo ezininzi eziphambili, ukusuka kwimveliso yezinto eziluhlaza ukuya kwindibano yokugqibela yengundoqo. Isinyathelo sokuqala kwinkqubo yokuvelisa kukuveliswa kwentsimbi yombane, nokuba yi-GO okanye i-NGO, ebandakanya ukulawulwa kwe-annealing kunye nokuqengqeleka kwentsimbi ukufezekisa iipropati ezifunwayo zamagnetic. Oku kulandelwa kukusikwa kunye nokupakishwa kweelaminations ukwenza ubume obungundoqo kunye nobukhulu.

Inkqubo ye-lamination ibalulekile ekunciphiseni ilahleko engundoqo, njengoko inceda ekunciphiseni ilahleko yangoku ye-eddy ngokwahlula i-core ibe ngamaleko amancinci. Ezi zingqimba ezibhityileyo, ngokuqhelekileyo ukusuka kwi-0.25mm ukuya kwi-0.35mm ubukhulu, zifakwe kwi-insulated ukusuka komnye nomnye ukuthintela ukuhamba kwemisinga ye-eddy. Ukupakishwa kunye nokufakwa kwe-laminations kulawulwa ngononophelo ukuze kuqinisekiswe ulungelelwaniso oluchanekileyo kunye nezithuba ezincinci zomoya, ezinokuchaphazela kakhulu iimpawu zemagnethi ezingundoqo.

Emva kokuba i-laminations ifakwe, i-core igxininiswe okanye idibaniswe kunye ukuze yenze isakhiwo esiqinileyo, esilungele ukuhlanganiswa kwindibano ye-transformer. Iinkqubo zokuvelisa ezibandakanyekayo kulwakhiwo olungundoqo lwe-transformer zikhethekileyo kwaye zifuna imilinganiselo engqongqo yokulawula umgangatho ukuqinisekisa ukuba imveliso yokugqibela ihlangabezana nemigangatho yokusebenza efunekayo. Kwicandelo elilandelayo, siza kuxubusha iintlobo ezahlukeneyo ze-transformer cores kunye nezicelo zabo ezithile.

Iindidi zeTransformer Cores

Ii-cores zeTransformer ziza kwiimilo ezahlukeneyo kunye nokulungelelaniswa, nganye yenzelwe izicelo ezithile kunye neemeko zokusebenza. Olona hlobo luqhelekileyo lwe-transformer core yi-core laminated, equkethe i-laminations edibeneyo yentsimbi yombane okanye ezinye izinto eziphambili. I-Laminated cores isetyenziswa ngokubanzi kwiziguquli zamandla, iziguquli zokusasaza, kunye nezinye izicelo eziphezulu zamandla ngenxa yeempawu zazo ezigqwesileyo zemagneti kunye nelahleko ephantsi.

Ukongeza kwii-cores laminated, kukho kwakhona ii-toroidal cores, ezenziwe kwi-strip eqhubekayo yesilonda sombane kwi-ring-like shape. I-Toroidal cores ibonelela ngezibonelelo ezinjengokuncitshiswa kokuvuza kwamagnetic kunye nelahleko esezantsi, ezenza zilungele iziguquli eziphezulu kunye nezicelo ezifuna uyilo olubambeneyo. Olunye uhlobo lwe-transformer core yi-shell-type core, equkethe i-cylindrical okanye i-rectangular winding ehlanganiswe yi-core magnetic. I-shell-type cores isetyenziswa ngokuqhelekileyo kwi-high-voltage kunye ne-high-current transformers, enika ukudibanisa okusebenzayo kunye nokunciphisa ukuvuza kwe-flux.

Uhlobo ngalunye lwe-transformer core lunenzuzo kunye nokulinganiselwa, okwenza ukuba lulungele izicelo ezithile ezisekelwe kwizinto ezifana nokusebenza kakuhle, ubungakanani kunye neendleko. Icandelo lokugqibela liya kunika isishwankathelo seenkcukacha eziphambili ezichazwe kweli nqaku, zinika umboniso obanzi wokwakhiwa kwe-transformer core kunye nokubaluleka kwayo kummandla wobunjineli bombane.

Ukuqukumbela

Ekugqibeleni, ukwakhiwa kwee-cores ze-transformer kudlala indima ebalulekileyo ekusebenzeni, ukusebenza, kunye nokuthembeka kweenguqu. Ukukhethwa kwezinto eziphathekayo, kubandakanywa intsimbi yombane, isinyithi se-amorphous, kunye ne-ferrite, ichaphazela ngokuthe ngqo iimpawu zemagnethi kunye nelahleko engundoqo. Iinkqubo zokuvelisa ezibandakanyekayo ekuveliseni ii-cores ze-transformer, ezifana ne-lamination, stacking, kunye ne-bonding, zibaluleke kakhulu ekubunjweni kweempawu eziphambili kunye nokunciphisa ilahleko.

Ukuqonda iintlobo ezahlukeneyo ze-cores ze-transformer, ezibandakanya i-laminated, i-toroidal, kunye ne-shell-type cores, ivumela ukukhethwa kweyona nto ifanelekileyo kwisicelo esinikezelweyo, nokuba ngaba ukuveliswa kwamandla, ukuhanjiswa, okanye ukusetyenziswa kwe-high-frequency applications. Ngokufumana ukuqonda okunzulu kolwakhiwo olungundoqo lwe-transformer, iinjineli kunye nabavelisi banokwandisa ukuyila kunye nokusebenza kwee-transformers, ekugqibeleni bafake isandla ekusebenzeni kunye nokuthembeka kokuhanjiswa kwamandla kunye neenkqubo zokuhambisa.

Ukuqukumbela, izixhobo kunye neenkqubo zokuvelisa ezibandakanyekayo kulwakhiwo olungundoqo lwe-transformer zizinto ezibalulekileyo zomsebenzi kunye nokusebenza ngokubanzi kwe-transformer. Ngokuqonda ubucukubhede bokwakhiwa kwe-transformer core, iinjineli kunye nabavelisi banokwenza izigqibo ezinolwazi eziphucula ukusebenza kakuhle, ukuthembeka, kunye neendleko ezisebenzayo zabaguquli, ngaloo ndlela banegalelo kuzinzo kunye nomgangatho wokusasazwa kwamandla kunye nokuhanjiswa kwamanethiwekhi.
