Emkhakheni wobunjiniyela kagesi kanye nokusatshalaliswa kwamandla, ukukhethwa kwezinto eziyinhloko zama-transformer nama-inductor kudlala indima ebalulekile ekunqumeni ukusebenza kahle nokusebenza kwemishini. Izinketho ezimbili ezidumile zezinto eziyinhloko yi-amorphous core kanye ne-nanocrystalline core, ngayinye inikeza izakhiwo nezinzuzo ezihlukile. Kulesi sihloko, sizohlola izici ze-amorphous core kanye ne-nanocrystalline core, bese sihlola umehluko phakathi kwalokhu okubili.
Iyini i-Amorphous Core?
An umongo ongemuhleuhlobo lwezinto eziyinhloko ezisebenza ngogesi ezibonakala ngesakhiwo sazo se-athomu esingeyona ikristalu. Lolu hlelo oluyingqayizivele lwe-athomu lunikeza ama-core angenawo ugesi izakhiwo zawo ezihlukile, okuhlanganisa ukulahlekelwa okuphansi komgogodla, ukungena okuphezulu, kanye nezakhiwo ezinhle kakhulu zikagesi. Izinto ezivame kakhulu ezisetshenziselwa ama-core angenawo ugesi yi-alloy esekelwe ensimbini, evame ukuqukethe izinto ezifana nensimbi, i-boron, i-silicon, ne-phosphorus.
Imvelo yokungakhiqizi kwama-core angenawo ulwelwesi lwekristalu iholela ekuhleleni okungahleliwe kwama-athomu, okuvimbela ukwakheka kwama-domain amagnetic futhi kunciphisa ukulahleka kwamanje kwe-eddy. Lokhu kwenza ama-core angenawo ulwelwesi asebenze kahle kakhulu ekusetshenzisweni lapho ukulahleka kwamandla aphansi kanye nokuvuleka okuphezulu kwamandla kagesi kubalulekile, njengakuma-transformer okusabalalisa amandla kanye nama-inductors aphezulu.
Ama-core angenawo ukwakheka akhiqizwa kusetshenziswa inqubo yokuqina okusheshayo, lapho i-alloy encibilikisiwe icinywa khona ngesivinini esikhulu kakhulu ukuvimbela ukwakheka kwezakhiwo zekristalu. Le nqubo iphumela esakhiweni se-athomu esingenalo uhlelo olude, okwenza izinto zibe nezakhiwo zazo ezihlukile.
Iyini i-Nanocrystalline Core?
Ngakolunye uhlangothi, i-nanocrystalline core uhlobo lwezinto eziyinhloko ezisebenza ngogesi eziqukethe izinhlamvu ezikristalu ezinobukhulu be-nanometer ezifakwe ku-matrix engabonakali. Lesi sakhiwo sezigaba ezimbili sihlanganisa izinzuzo zezinto ezikristalu nezingabonakali, okuholela ezimpahleni ezinhle kakhulu zikagesi kanye nobuningi obukhulu bokugcwala kwamanzi.
Ama-core e-Nanocrystallinengokuvamile zenziwa ngenhlanganisela yensimbi, i-nickel, ne-cobalt, kanye nokwengezwa okuncane kwezinye izinto ezifana nethusi ne-molybdenum. Isakhiwo se-nanocrystalline sinikeza ukuvuleka okuphezulu kwamagnetic, ukucindezela okuphansi, kanye nokuqina kokushisa okuphezulu, okwenza kufaneleke ukusetshenziswa kwamandla aphezulu kanye nama-transformer asebenza ngesivinini esiphezulu.
Umehluko phakathi kwe-Amorphous Core ne-Nanocrystalline Core
Umehluko omkhulu phakathi kwama-core angenawo ukwakheka kanye nama-core angenawo ukwakheka usekwakhekeni kwawo kwe-athomu kanye nezakhiwo zamagnetic eziphumela kukho. Ngenkathi ama-core angenawo ukwakheka anesakhiwo esingeyona i-crystalline ngokuphelele, ama-core angenawo ukwakheka abonisa isakhiwo esinezigaba ezimbili esakhiwe ngama-crystalline asayizi we-nanometer ngaphakathi kwe-matrix engenawo ukwakheka.
Ngokuphathelene nezakhiwo zamagnetic,ama-core angenasimozaziwa ngokulahlekelwa kwazo okuphansi komongo kanye nokuvuleka okuphezulu, okwenza zibe zilungele ukusetshenziswa lapho ukusebenza kahle kwamandla kubaluleke kakhulu. Ngakolunye uhlangothi, ama-nanocrystalline cores anikeza ukuminyana okuphezulu koketshezi kanye nokuqina kokushisa okuphezulu, okwenza afaneleke ukusetshenziswa kwamandla aphezulu kanye nemvamisa ephezulu.
Omunye umehluko obalulekile inqubo yokukhiqiza. Ama-core angenawo ukwakheka akhiqizwa ngokuqina okusheshayo, okuhlanganisa ukucima i-alloy encibilikisiwe ngesivinini esiphezulu ukuvimbela ukwakheka kwamakristalu. Ngokuphambene nalokho, ama-core angenawo ukwakheka avame ukukhiqizwa ngokunamathisela nokulawula ama-ribbons angenawo ukwakheka, okuholela ekwakhekeni kwama-grain ekristalu angange-nanometer ngaphakathi kwento.
Izinto Okucatshangelwayo Ngesicelo
Uma ukhetha phakathi kwama-core angenawo umfuziselo nama-core angenawo umfuziselo we-nanocrystalline wohlelo lokusebenza oluthile, kunezinto eziningana okudingeka zicatshangelwe. Kuzinhlelo zokusebenza ezibeka phambili ukulahlekelwa kwamandla aphansi kanye nokusebenza kahle okuphezulu, njengakuma-transformer okusabalalisa amandla kanye nama-inductors aphezulu, ama-core angenawo umfuziselo avame ukuba yisinqumo esikhethwayo. Ukulahlekelwa kwawo okuphansi komgogodla kanye nokungena kwamanzi okuphezulu kuwenza afaneleke kahle kulezi zinhlelo zokusebenza, okufaka isandla ekongeni amandla jikelele kanye nokusebenza okuthuthukisiwe.
Ngakolunye uhlangothi, ezinhlelweni zokusebenza ezidinga ukuminyana okuphezulu kokugcwala kwamanzi, ukuzinza okuphezulu kokushisa, kanye namakhono okuphatha amandla aphezulu, ama-nanocrystalline cores afaneleka kakhulu. Lezi zakhiwo zenza ama-nanocrystalline cores afaneleke kakhulu kuma-transformer anamandla aphezulu, izinhlelo zokusebenza ze-inverter, kanye nezinsiza zamandla ezivame kakhulu, lapho ikhono lokusingatha ukuminyana okuphezulu kwamandla kazibuthe nokugcina ukuzinza ngaphansi kwezimo zokusebenza ezahlukahlukene libalulekile.
Ekuphetheni, ama-core angenasimo kanye nama-core angenasici anikeza izinzuzo ezihlukile futhi aklanyelwe izidingo ezithile zohlelo lokusebenza. Ukuqonda umehluko esakhiweni sawo se-athomu, izakhiwo zikagesi, kanye nezinqubo zokukhiqiza kubalulekile ekwenzeni izinqumo ezinolwazi lapho kukhethwa izinto eziyinhloko zama-transformer nama-inductor. Ngokusebenzisa izici ezihlukile zezinto ezibonakalayo, onjiniyela nabaklami bangenza ngcono ukusebenza kanye nokusebenza kahle kwezinhlelo zabo zokusatshalaliswa kwamandla kanye nokuguqulwa kwamandla, ekugcineni banikele ekuthuthukisweni kokusebenza kahle kwamandla kanye nobuchwepheshe bamandla obuqhubekayo.
