Uma kuqhathaniswa nama-transformer e-ferrite core yendabuko, ama-transformer e-amorphous core athole ukunakwa okukhulu eminyakeni yamuva nje ngenxa yokwakheka kwawo okuhlukile kanye nokusebenza okuthuthukisiwe. Lawa ma-transformer enziwe ngezinto ezikhethekile ezibizwa ngokuthi i-amorphous alloy, ezinezakhiwo ezivelele ezenza kube ukukhetha kokuqala kwezinhlelo zokusebenza ezahlukahlukene. Kulesi sihloko, sizohlola ukuthi iyini ngempela i-amorphous core, sigqamise umehluko phakathi kwama-transformer e-amorphous core nama-transformer e-ferrite core, futhi sixoxe ngezinzuzo zokusebenzisaumongo ongemuhleama-transformer.
Ngakho-ke, iyini i-core magnetic engenawo umorphous? Ama-core magnetic angenawo umorphous aqukethe imichilo emincane ye-alloy eyakhiwe yizinto ezahlukahlukene zensimbi, ngokuvamile kufaka phakathi i-iron njenge-element eyinhloko kanye nenhlanganisela ye-boron, i-silicon, ne-phosphorus. Ngokungafani nezinto ezikristalu kuma-core e-ferrite, ama-athomu kuma-alloy angenawo umorphous awabonisi isakhiwo se-athomu esijwayelekile, yingakho igama elithi "amorphous." Ngenxa yalolu hlelo oluyingqayizivele lwe-athomu, ama-core angenawo umorphous anezakhiwo ezinhle kakhulu ze-magnetic.
Umehluko obaluleke kakhulu phakathi kwama-transformer e-amorphous core nama-ferrite core yizinto zawo eziyinhloko. Ama-cores e-amorphous asebenzisa ama-alloy a-amorphous ashiwo ngenhla, kuyilapho ama-ferrite core enziwa ngama-compounds e-ceramic aqukethe i-iron oxide nezinye izinto. Lo mehluko ezintweni eziyinhloko uphumela ezicini ezahlukene ze-transformer kanye nokusebenza kwayo.
Enye yezinzuzo eziyinhloko ze-umongo ongemuhleAma-transformer ayindlela yawo yokulahlekelwa okukhulu kwe-core. Ukulahlekelwa okukhulu kubhekisela emandleni ahlakazekile ku-core ye-transformer, okuholela ekuchithekeni kwamandla kanye nokwanda kokukhiqizwa kokushisa. Uma kuqhathaniswa nama-ferrite cores, ama-amorphous cores anokulahlekelwa okuphansi kakhulu kwe-hysteresis kanye ne-eddy current, okuholela ekusebenzeni kahle okuphezulu kanye namazinga okushisa aphansi okusebenza. Ukuthuthukiswa kokusebenza kahle okungu-30% kuya ku-70% uma kuqhathaniswa nama-transformer avamile kwenza ama-amorphous core transformers abe inketho ekhangayo embonini yokonga amandla.
Ngaphezu kwalokho, ama-core angenawo umklamo anezakhiwo ezinhle kakhulu zamagnetic, okuhlanganisa nobuningi be-flux yokugcwala okuphezulu. Ubuningi be-flux yokugcwala kwe-magnetic yokugcwala bubhekisela ekugelezeni okuphezulu kwe-magnetic okungafakwa yizinto eziyinhloko. Ama-alloy angenawo umklamo anobuningi be-flux yokugcwala okuphezulu uma kuqhathaniswa nama-core e-ferrite, okuvumela ama-transformer amancane, alula kanye nobuningi bamandla obukhuphukile. Le nzuzo inenzuzo ikakhulukazi ekusetshenzisweni lapho imikhawulo yobukhulu nesisindo ibaluleke kakhulu, njenge-electronics yamandla, izinhlelo zamandla avuselelekayo kanye nezimoto zikagesi.
Enye inzuzo yama-transformer e-core angenawo ukwakheka ukusebenza kwawo okuphezulu kakhulu kwemvamisa ephezulu. Ngenxa yesakhiwo sawo esiyingqayizivele se-athomu, ama-alloy angenawo ukwakheka abonisa ukulahlekelwa okuphansi kwe-core kuma-frequency aphezulu, okwenza abe afaneleke kakhulu ekusetshenzisweni okubandakanya ukunciphisa ukuphazamiseka kwe-electromagnetic (EMI) kwama-frequency aphezulu. Lesi sici senza ama-transformer e-core angenawo ukwakheka akwazi ukucindezela ngempumelelo umsindo we-EMI, ngaleyo ndlela athuthukise ukuthembeka kohlelo futhi anciphise ukuphazamiseka emishinini kagesi ebucayi.
Naphezu kwalezi zinzuzo,umongo ongemuhleAma-transformer anemikhawulo ethile. Okokuqala, izindleko zama-alloy angenawo umanyolo ziphakeme kunezinto ze-ferrite, okuthinta izindleko zokutshalwa kwezimali kokuqala kwe-transformer. Kodwa-ke, ukonga amandla kwesikhathi eside okutholakala ngokusebenza kahle okukhulu kuvame ukukhokhela izindleko zokuqala eziphakeme. Okwesibili, izakhiwo zemishini zama-alloy angenawo umanyolo ngokuvamile ziphansi kunezo zama-ferrite cores, okwenza zibe sengozini enkulu yokucindezeleka komshini kanye nomonakalo ongaba khona. Ukucatshangelwa kokuklama okufanele kanye namasu okucubungula kubalulekile ekuqinisekiseni ukuthi ama-transformer angenawo umanyolo ahlala isikhathi eside futhi athembekile.
Ngamafuphi, ama-transformer e-amorphous core anezinzuzo eziningi kune-transformer ye-ferrite core yendabuko. Ukulahlekelwa kwawo okunciphile kwe-core, ukusebenza okuphezulu kwe-magnetic, ukusebenza kahle kakhulu kwemvamisa ephezulu, kanye nosayizi omncane nesisindo kuwenza abe ukukhetha okukhangayo kwezinhlelo ezahlukahlukene. Njengoba isidingo sezinhlelo ezisebenzisa amandla kahle siqhubeka nokukhula, ama-transformer e-amorphous core cishe azodlala indima ebalulekile ekuhlangabezaneni nalezi zidingo futhi aqhube izimboni ziye ekusaseni eliluhlaza nelizinzile.
