Iitransformer zizinto ezibalulekileyo kwinkqubo yokusasazwa kwamandla kunye nokuhambisa, zisebenza ukunyusa okanye ukunciphisa iivoltage njengoko kufuneka ukuqinisekisa ukunikezelwa kombane okusebenzayo nokuthembekileyo. Intliziyo yetransformer nganye iyindawo ephambili yetransformer, edlala indima ebalulekileyo ekusebenzeni kwesixhobo. Ukuqonda ukwakhiwa kwee-transformer cores kubalulekile ekwenzeni ngcono ukusebenza kwazo kunye nokuthembeka kwazo. Kweli nqaku, siza kujonga izixhobo kunye neenkqubo zokuvelisa ezibandakanyekayo ekwakheni i-transformer core, sinike ulwazi oluxabisekileyo kwiinjineli, abavelisi, kunye nabani na onomdla kubuchwepheshe obusemva kweetransformer.

Iziseko zeeTransformer Cores

Ii-transformer cores zibalulekile ekusebenzeni kwee-transformers, zisebenza njengendlela yemagnethi evumela ukudluliselwa kwamandla phakathi kwee-windings eziphambili nezesibini. Ezi cores zihlala zakhiwe ngeeshiti zentsimbi yombane ezifakwe i-laminated, ezihlanganiswe ndawonye ukuze zenze isakhiwo esiqinileyo, kodwa esingena ngemagnethi. Umsebenzi oyintloko we-core kukubonelela ngendlela engathathi cala ye-magnetic flux eveliswa yi-primary winding, ukuqinisekisa ukudluliselwa kwamandla ngokufanelekileyo kwi-secondary winding. Enyanisweni, i-core isebenza njengekhonkco lemagnethi phakathi kwee-windings eziphambili nezesibini, okuvumela ukuguqulwa kwamandla ombane ukusuka kwinqanaba elinye le-voltage ukuya kwelinye.

Ukukhethwa kwezinto ezisetyenziswa kwi-transformer core kubalulekile, njengoko kuchaphazela ngqo ukusebenza kakuhle kwesixhobo, ilahleko, kunye nokusebenza ngokubanzi. Kwicandelo elilandelayo, siza kuhlola izinto ezahlukeneyo ezisetyenziswa ekwakheni i-transformer core kunye neempawu zazo.

Izinto ezisetyenziswa kwiTransformer Cores

Izinto ezisetyenziswa kakhulu kwii-transformer cores yintsimbi yombane, eyenzelwe ngokukodwa usetyenziso olufuna ukuvuleka okuphezulu kwemagnethi kunye nokulahleka okuphantsi kwe-core. Intsimbi yombane ifumaneka kwiintlobo ezimbini eziphambili: i-grain-oriented (GO) kunye ne-non-grain-oriented (NGO). Intsimbi yombane ye-GO iveliswa kusetyenziswa inkqubo ekhethekileyo yokuvelisa elungelelanisa iinkozo zekristale kwintsimbi kwicala elithile, nto leyo ebangela iipropati eziphezulu zemagnethi kuloo ndlela. Oku kuyenza ifaneleke ngakumbi kwii-transformers ezisebenzayo kakhulu, ezifana nezo zisetyenziswa ekuveliseni nasekusasazeni umbane.

Kwelinye icala, intsimbi yombane ye-NGO iveliswa ngaphandle kolwalathiso olukhethwayo lweenkozo, nto leyo eyenza ukuba ifaneleke ngakumbi kwizicelo apho i-magnetic flux yahluka kwicala, njengakwii-transformers zokusasaza. Zombini ezi ntlobo zentsimbi yombane zibonelela ngokukhanya okuphezulu kwe-magnetic kunye nokulahleka okuphantsi kwe-core, nto leyo eyenza ukuba zilungele ukwakhiwa kwe-transformer core.

Ukongeza kwintsimbi yombane, ezinye izinto ezifana nentsimbi engaguqukiyo kunye ne-ferrite nazo ziyasetyenziswa kwiintlobo ezithile zee-transformers. Ii-cores zentsimbi ezingaguqukiyo zenziwe nge-alloy engeyiyo i-crystalline, ebonisa ilahleko ephantsi kakhulu kunentsimbi yombane yendabuko. Oku kuzenza zibe lukhetho oluhle kakhulu kwii-transformers ezisebenzayo kakhulu, nangona zibiza kakhulu. Ii-cores ze-Ferrite, kwelinye icala, zisetyenziswa rhoqo kwii-transformers ezinamaza aphezulu kunye namandla aphantsi ngenxa yeempawu zazo ezintle zemagnethi kumaza aphezulu.

Ukukhethwa kwezinto eziphambili kuxhomekeke kwizinto ezahlukeneyo ezifana nokusetyenziswa kwetransformer, iimfuno zokusebenza kakuhle, kunye nokuqwalaselwa kweendleko. Kwicandelo elilandelayo, siza kuhlola iinkqubo zokuvelisa ezibandakanyekayo ekwakhiweni kwetransformer core, ezidlala indima ebalulekileyo ekubumbeni iimpawu zokugqibela zecore.

Iinkqubo Zokuvelisa Ii-Transformer Cores

Ukwenziwa kwee-transformer cores kubandakanya iinkqubo ezininzi ezibalulekileyo, ukususela ekuvelisweni kwezinto eziluhlaza ukuya ekuhlanganisweni kokugqibela kwe-core. Inyathelo lokuqala kwinkqubo yokwenziwa kukuveliswa kwentsimbi yombane, nokuba yi-GO okanye yi-NGO, equka ukutsalwa nokufakwa kwentsimbi okulawulwayo ukuze kufezekiswe iipropati zemagnethi ezifunekayo. Oku kulandelwa kukunqunyulwa nokufakwa kwee-laminations ukuze kwenziwe imo kunye nobukhulu be-core.

Inkqubo yokugquma ibaluleke kakhulu ekunciphiseni ilahleko ze-core, njengoko inceda ekunciphiseni ilahleko ze-eddy current ngokwahlula i-core ibe zii-layers ezincinci. Ezi layers zincinci, eziqhele ukuba phakathi kwe-0.25mm ukuya kwi-0.35mm ubukhulu, zigqunywa ngobushushu obunye ukuze kuthintelwe ukuhamba kwe-eddy currents. Ukufakwa kunye nokugquma kwe-laminations kulawulwa ngononophelo ukuqinisekisa ukulungelelaniswa ngokuchanekileyo kunye nezithuba ezincinci zomoya, ezinokuchaphazela kakhulu iimpawu zemagnethi ze-core.

Nje ukuba ii-laminations zibekwe ndawonye, ​​umbindi uyabotshelelwa okanye udityaniswe kunye ukuze kwenziwe isakhiwo esiqinileyo, silungele ukuhlanganiswa kwindibano ye-transformer. Iinkqubo zokuvelisa ezibandakanyekayo kulwakhiwo lwe-transformer core zikhethekile kakhulu kwaye zifuna amanyathelo angqongqo okulawula umgangatho ukuqinisekisa ukuba imveliso yokugqibela iyahlangabezana nemigangatho yokusebenza efunekayo.

Ukongeza kwii-cores ezifakwe i-laminated, kukwakho nee-cores ze-toroidal, ezenziwe nge-strip eqhubekayo ye-electric steel wound ibe yimo efana ne-ring. Ii-cores ze-Toroidal zibonelela ngeenzuzo ezifana nokuvuza okuncinci kwe-magnetic kunye nokulahleka okuncinci kwe-core, okwenza ukuba zilungele ii-transformers ezisebenzayo kakhulu kunye nezicelo ezifuna uyilo oluncinci. Olunye uhlobo lwe-transformer core yi-core yohlobo lwe-shell, equlathe i-cylindrical okanye i-rectangular winding ejikelezwe yi-magnetic core. Ii-cores zohlobo lwe-Shell zisetyenziswa rhoqo kwii-transformers ezine-voltage ephezulu kunye ne-high-current, ezibonelela nge-magnetic coupling esebenzayo kunye nokuvuza okuncinci kwe-flux.

Uhlobo ngalunye lwe-transformer core luneengenelo kunye nemida yalo, nto leyo eyenza ukuba ifaneleke kwizicelo ezithile ngokusekelwe kwizinto ezifana nokusebenza kakuhle, ubungakanani, kunye neendleko. Icandelo lokugqibela liza kubonelela ngesishwankathelo seengqiqo ezibalulekileyo ezigutyungelwe kweli nqaku, libonelela ngesishwankathelo esipheleleyo sokwakhiwa kwe-transformer core kunye nokubaluleka kwayo kwicandelo lobunjineli bombane.
