Umbindi wetransformer udlala indima ebalulekileyo ekusebenzeni kwayo, kwaye iintlobo ezahlukeneyo kunye nezakhiwo zeetransformer cores ziye zavela kwiminyaka edlulileyo. Kweli nqaku, siza kungena nzulu kwihlabathi leetransformer cores, sichaze iintlobo ezahlukeneyo kunye nezakhiwo kwaye sifumane ulwazi oluxabisekileyo malunga nemigaqo yokusebenza kunye nokusetyenziswa kwazo.

Ukuqonda iiTransformer Cores

I-core ye-transformer yinxalenye ebalulekileyo enoxanduva lokudluliselwa kwe-magnetic flux. Isebenza njengendlela ye-magnetic field kwaye inefuthe ekusebenzeni kakuhle nasekusebenzeni kwe-transformer. Ii-transformer cores zihlala zenziwe ngezinto ze-ferromagnetic, ezifana ne-laminated iron okanye intsimbi, ezibonisa ukuvuleka okuphezulu kwe-magnetic.

Iintlobo zeeTransformer Cores

Kukho iintlobo ezimbini eziphambili zee-transformer cores: ii-core-type cores kunye nee-shell-type cores. Uhlobo ngalunye luneempawu zalo ezizodwa, iingenelo, kunye nokusetyenziswa kwalo.

IiCores zeTransformer zohlobo oluphambili

Ii-core-type transformer cores zinombindi wemagnethi one-winding kumacala omabini aphambili nakwesibini. Le core yenziwe ngee-laminated iron okanye ii-steel sheets ezibizwa ngokuba zii-laminations. Ii-laminations zihlanganiswa ndawonye ukuze zenze i-core eqinileyo enemingxuma embindini ukuze i-winding idlule.

Ii-core-type transformer cores zibonelela ngokusebenza okuphezulu xa kufikwa kulawulo lwamandla kunye ne-voltage. Zinoxinano lwamandla aphezulu, nto leyo ezenza zifaneleke kwii-high-power transformers. Ukongeza, isakhiwo esine-laminated sinciphisa ilahleko yamandla e-eddy, nto leyo ekhokelela ekusebenzeni ngcono.

Ezi cores zisetyenziswa kakhulu kwiitransformer zamandla, apho kufuneka udluliselo lwamandla aphezulu, njengakwizikhululo zombane kunye neenethiwekhi zokusasazwa kwamandla. Zikwasetyenziswa nakwizicelo ezinkulu zoshishino, ezifana noomatshini abakhulu kunye nezityalo zokwenza.

IiCores zeTransformer zohlobo lweShell

Ii-cores ze-transformer zohlobo lwe-shell, ezaziwa ngokuba zii-cores zohlobo lwe-wound, zine-windings zazo ezibekwe ngaphandle kwe-core. I-core ine-windings ezimbini ezahlukeneyo, i-windings yokuqala neyesibini, ezifakwe kwi-central limb. I-core yentsimbi okanye yentsimbi kwii-transformers zohlobo lwe-shell imile njengesakhelo sesikwere okanye se-rectangular.

Ii-cores ze-transformer zohlobo lwe-shell zineengenelo ezininzi kunee-cores zohlobo lwe-core. Zibonelela ngenkqubo yokupholisa engcono, njengoko ii-windings zingaphandle kwe-core, nto leyo evumela ukujikeleza okusebenzayo kwe-cooling medium. Ii-cores zohlobo lwe-shell zikwanokufikelela lula kwii-windings ukuze zilungiswe kwaye zigcinwe.

Ezi cores zifumana ukusetyenziswa kwazo kwiitransformer zokusasaza, apho kufuneka amandla aphantsi. Zisetyenziswa kakhulu kwiindawo zokuhlala nezorhwebo ekuguquleni i-voltage kunye nokusasazwa kwamandla.

Ulwakhiwo lweeTransformer Cores

Ngaphandle kweentlobo, ii-transformer cores nazo ziza ngezakhiwo ezahlukeneyo ngokusekelwe kulungiselelo lwe-laminations kunye nolwakhiwo lwe-winding. Makhe sihlolisise izakhiwo ezahlukeneyo kunye neempawu zazo.

Isakhiwo se-EI core sifumene igama laso ngenxa yesimo se-laminations. Ii-laminations zibekwe ngendlela efana noonobumba u-E no-I, nto leyo enika usasazo olungcono lwe-magnetic flux kunye nokunciphisa ilahleko ze-magnetic. Esi sakhiwo sisetyenziswa kakhulu kwii-power transformers, ukuqinisekisa ukuhanjiswa kwamandla ngokufanelekileyo kunye nelahleko eziphantsi ze-core.

Inzuzo yesakhiwo se-EI core ikukunciphisa i-magnetizing current kunye nokulawulwa kwe-voltage okuphuculweyo. Izikhewu phakathi kwe-E kunye ne-I laminations zinceda ukuthintela ukwakheka kwe-eddy currents, nto leyo ekhokelela ekulahlekeni kwamandla okuphantsi kunye nokusebenza kakuhle okwandisiweyo.

2. U Core

Ulwakhiwo lwe-U core lufana nonobumba u-U, kunye nee-windings ezibekwe kwilungu elinye. Olu lwakhiwo lusetyenziswa rhoqo kwii-transformers ze-voltage ephantsi kunye nezokusasazwa. Lunika uyilo oluncinci kunye nokulula kokwenziwa, okwenza kube lula ukubiza imali eninzi kwimveliso enkulu.

I-U core inika indlela emfutshane ye-magnetic flux, inciphisa i-magnetizing current kwaye ibangela ukusebenza kakuhle okuphuculweyo. Ikwabonisa ukuncipha kokuhamba komoya okuvuzayo kunye nokulahleka komoya okuphantsi, okwenza ukuba ibe lukhetho olufanelekileyo kwizicelo zamandla aphantsi.
