Icore inoxanduva lokudlulisa amandla emagnethi ukusuka kwi-primary winding ukuya kwi-secondary winding, nto leyo ekhokelela ekuguqulweni kwevolthi. Ukuqonda iintlobo ezahlukeneyo zeetransformer cores ezikhoyo kubalulekile ekukhetheni icore efanelekileyo kwizicelo ezithile. Kweli nqaku, siza kuphonononga iintlobo ezahlukeneyo zeetransformer core size sihlolisise iimpawu zazo, iingenelo, kunye nokusetyenziswa kwazo.

Isiguquli seNsimbi esingundoqo

I-iron core transformer yenye yezona ntlobo ze-transformer core ezisetyenziswa kakhulu. Njengoko igama lisitsho, ine-laminated iron core ebotshelelwe ngee-coils eziphambili nezesibini. Ii-laminations, ezenziwe ngelaphu elincinci le-silicon steel ekumgangatho ophezulu, zihlanganiswe ndawonye ukunciphisa ilahleko ye-eddy current ngaphakathi kwe-core.

I-transformer yentsimbi ineenzuzo ezininzi. Okokuqala, inika umgangatho ophezulu wokungena kwemagnethi, iqinisekisa ukudluliselwa kwe-magnetic flux ngokufanelekileyo phakathi kweekhoyili. Oku kukhokelela kwi-hysteresis ephantsi kunye nokulahleka kombane we-eddy, okubangela ukwanda kokusebenza kakuhle. Ukongeza, olu hlobo lwentsimbi lubonisa uzinzo oluqinileyo loomatshini kwaye lunokumelana namanqanaba aphezulu obushushu kunye noxinzelelo lombane.

Iitransformer zentsimbi zisetyenziswa kwizicelo ezahlukeneyo, kubandakanya iinkqubo zokuhambisa nokuhambisa umbane, ulawulo lwevolthi, kunye nokunikezelwa kwamandla ombane kwizixhobo zoshishino. Ukuguquguquka kwazo, ukuthembeka kwazo, kunye nokusebenza kakuhle kweendleko kuzenza zithandwe kakhulu kwishishini lombane.

Isiguquli seMoto oPhambili

Ngokungafaniyo ne-iron core transformer, i-air core transformer ayisebenzisi naziphi na izinto ze-ferromagnetic ngaphakathi kwe-core yayo. Endaweni yoko, ixhomekeke emoyeni njengesixhobo sokudlulisa i-magnetic flux. Ii-coil eziphambili nezesibini zijikelezwe kwityhubhu engenanto ye-magnetic hollow okanye yangaphambili, esebenza njengesakhiwo sokuxhasa.

Iitransformer ze-air core zineempawu ezininzi eziluncedo. Okokuqala, zibonisa ilahleko ephantsi kakhulu, njengoko kungekho zinto ze-ferromagnetic ezikhoyo ezinokubangela i-hysteresis okanye ilahleko yamandla e-eddy. Ngenxa yoko, ukusebenza kakuhle kweetransformer ze-air core kuphezulu kakhulu. Ngaphezu koko, ziyakwazi ukumelana nokugcwala kwamandla amakhulu ngaphandle kokuphazamiseka okukhulu.

Nangona kunjalo, ii-air core transformers nazo zinemida ethile. Ngenxa yokungabikho kwezinto ze-ferromagnetic, uxinano lwe-magnetic flux luphantsi kakhulu xa luthelekiswa nee-iron core transformers. Ngenxa yoko, ii-air core transformers azisebenzi kakuhle ngokubhekiselele ekudluliseleni amandla kwaye zihlala zisetyenziswa kuphela kwiindawo apho amanqanaba aphantsi ombane anele khona, njengakwiisekethe zerediyo (RF), ukufanisa i-impedance, kunye nokudluliselwa kwesignali ye-high-frequency.

I-Ferrite Core Transformer

Iitransformer ze-ferrite core zinomongo owenziwe nge-ferrite, into efana ne-ceramic eyenziwe yi-iron oxide kunye nezinye izinto zesinyithi. Olu hlobo lomongo lubonisa iipropati ezibalaseleyo zemagnethi, kubandakanya ukungena okuphezulu kunye nokuqhuba kombane okuphantsi. Izinto ze-ferrite zihlala zifumaneka kwiimo ezahlukeneyo, ezifana ne-toroidal (emile okwe-donut) okanye i-E-shape, okuvumela ukuguquguquka kuyilo lwe-transformer.

Enye yezona nzuzo ziphambili zee-ferrite core transformers kukukwazi kwazo ukusebenza kwiifrikhwensi eziphezulu. Ngenxa yokwakheka kwazo okwahlukileyo, zinelahleko ephantsi ye-eddy current, nto leyo eyenza ukuba zilungele ukusetyenziswa ezifuna ukudluliselwa kwamandla ngokufanelekileyo kwiifrikhwensi eziphezulu. Ngaphezu koko, ii-ferrite core transformers zinokuphatha uluhlu olubanzi lwamanqanaba ombane, ziqinisekisa uzinzo kunye nokuthembeka kwizixhobo ezahlukeneyo ze-elektroniki.

Ezi transformers zifumana usetyenziso olubanzi kwizixhobo zamandla ze-switch-mode, ii-transformers ezisebenza rhoqo, izixhobo zonxibelelwano, kunye nezixhobo ze-elektroniki ezifana noomabonwakude, iikhompyutha, kunye nezixhobo ze-audio. Ukudibana kweempawu zazo ezintle zemagnethi kunye nobukhulu obuncinci kwenza ii-transformers ze-ferrite core zifunwa kakhulu kwiinkqubo ze-elektroniki zanamhlanje.

I-Toroidal Core Transformer

I-toroidal core transformer ifumana igama layo kwimo ye-toroid ye-core yayo, efana ne-donut. Olu yilo lwe-core lubonelela ngeenzuzo ezininzi kunezinye iintlobo, nto leyo eyenza ukuba ithandwe kakhulu kwiintlobo ngeentlobo zezicelo. I-toroidal core idla ngokwakhiwa ngentsimbi ye-silicon elaminethiweyo, ejolise kwiingqolowa, evumela ukudluliselwa kwe-magnetic flux ngokufanelekileyo.

Enye yeenzuzo eziphambili zee-toroidal core transformers kukuba zixinene kwaye zinciphisa ubunzima. Imilo yazo engqukuva isusa izithuba zomoya, nto leyo ebangela uyilo olucwangcisiweyo ngakumbi. Ukongeza, ukungabikho kweekona okanye imiphetho kunciphisa ukuvuza kwemagnethi, okukhokelela ekuphuculweni kokusebenza kwamandla kunye nokunciphisa ukuphazamiseka kwe-electromagnetic (EMI). Ngaphezu koko, ii-toroidal core transformers zivelisa ingxolo encinci kunye nokungcangcazela xa kuthelekiswa nee-transformers ezinezinye iintlobo ze-core.

Ii-Toroidal core transformers zisetyenziswa kakhulu kwiinkqubo zesandi, izixhobo zonyango, ii-amplifier, izixhobo zamandla, kunye nezixhobo ezahlukeneyo ze-elektroniki ezifuna ubungakanani obuncinci kunye nokusebenza kakuhle okuphezulu.
