Iziguquli zizinto ezibalulekileyo kwiinkqubo zombane, zisebenza njengemithombo yokudlulisa amandla ombane phakathi kweesekethe ngelixa zigcina amanqanaba ombane. Ukusebenza kunye nokusebenza kwe-transformer kuxhomekeke kakhulu kwizinto eziphambili ezisetyenzisiweyo. Esi sikhokelo siphonononga iintlobo ezahlukeneyo zezinto ezingundoqo ze-transformer, sijonge kwiipropati kunye nokusetyenziswa kwazo. Nokuba uyinjineli yombane enamava, umntu onomdla, okanye umntu onomdla wokuba umbane ufikelela njani na ekhayeni lakho, ukuqonda ezi zixhobo kuya kukhulisa uxabiso lwakho ngezi zixhobo ziyimfuneko.

Iintsimbi zeSilicon zentsimbi

Intsimbi ye-silicon ngokuqinisekileyo yeyona nto ixhaphakileyo ye-transformer, eyaziwa ngokuba yimagnethi ephezulu kunye nelahleko ephantsi. Olu hlobo lwentsimbi luhlala luqulethe malunga ne-3% ye-silicon, iphucula iipropati zayo zokukhusela umbane kunye nokunciphisa ilahleko ye-hysteresis. Ukulahleka kwe-Hysteresis kwenzeka xa i-magnetization ye-core ilahla emva kwendawo yamagnetic, ekhokelela ekungaphumeleli.

Enye yeenzuzo eziphambili zentsimbi ye-silicon yindleko yayo. Esi sixhobo silinganisa ukusebenza kunye nexabiso, okwenza ukuba lulungele uluhlu olubanzi lwabaguquli, ukusuka kwezo zisetyenziselwa umbane wabathengi ukuya kwiiyunithi ezinkulu zoshishino. Ukwahluka okusekwe kwiinkozo zentsimbi ye-silicon, apho iinkozo zetsimbi zilungelelaniswa ngexesha lokwenziwa, zithandwa kakhulu kwiziguquli. Oku kulungelelaniswa kunciphisa ilahleko xa i-transformer isebenza phantsi kweemeko eziqhelekileyo zombane.

Iintsimbi zensimbi ze-silicon zinokufumaneka kwiifom ezahlukeneyo, kubandakanywa i-laminations kunye neeteyipu. I-Laminations ibhekisa kumaphepha abhityileyo apakishwe ukwenza undoqo, ngelixa iiteyiphu zibandakanya ukujija umcu oqhubekayo wentsimbi ye-silicon ujikeleze ifom engundoqo. Indlela nganye ineenzuzo zayo, kunye ne-laminations kulula ukuyibuyisela kwimeko yomonakalo kunye neeteyiphu ezinikezela ilahleko enokuthi ibe ngaphantsi ngenxa yamalungu ambalwa.

Ngaphandle kokusetyenziswa kwayo ngokubanzi, intsimbi yesilicon ayikho ngaphandle kwayo. Izinto eziphathekayo zinokuthi zixhomekeke kwiilahleko zangoku ze-eddy - imisinga eyenziwe ngaphakathi kwi-core ekhokelela ekutshitshisweni kwamandla njengobushushu. Ukuthomalalisa oku, abavelisi badla ngokugquma intsimbi ngomaleko wokugquma kwaye basebenzise ubuchule bokwenza iileya zibe bhityile, ukunciphisa iindlela zale misinga.

Amorphous Metal Cores

I-amorphous metal cores imele enye indlela ehambele phambili kwizinto zemveli njengentsimbi yesilicon.
