Poyerekeza ndi zosinthira zachikhalidwe za ferrite core, zosinthira za amorphous core zalandira chidwi kwambiri m'zaka zaposachedwa chifukwa cha mawonekedwe awo apadera komanso magwiridwe antchito apamwamba.Ma transformer awa amapangidwa kuchokera ku chinthu chapadera cha maginito chotchedwa amorphous alloy, chomwe chili ndi zinthu zapadera zomwe zimapanga chisankho choyamba pakugwiritsa ntchito zosiyanasiyana.M'nkhaniyi, tiwona zomwe kwenikweni amorphous core ndi, tikuwonetsa kusiyana pakati pa amorphous core transformers ndi ferrite core transformers, ndikukambirana za ubwino wogwiritsa ntchitoamorphous pachimakethiransifoma.
Ndiye, amorphous maginito core ndi chiyani?Amorphous maginito cores amakhala ndi timizere tating'onoting'ono ta alloy topangidwa ndi zinthu zosiyanasiyana zachitsulo, makamaka chitsulo monga chinthu choyambirira komanso kuphatikiza kwa boron, silicon, ndi phosphorous.Mosiyana ndi zinthu za crystalline muzitsulo za ferrite, ma atomu omwe ali mu amorphous alloys samawonetsa mawonekedwe a atomiki, choncho amatchedwa "amorphous."Chifukwa cha dongosolo la atomiki lapaderali, ma amorphous cores ali ndi maginito abwino kwambiri.
Kusiyana kwakukulu pakati pa ma amorphous core ndi ferrite core transfoma ndizinthu zawo zazikulu.Amorphous cores amagwiritsa ntchito ma amorphous alloys omwe tawatchulawa, pomwe ma ferrite cores amapangidwa kuchokera kuzinthu za ceramic zomwe zimakhala ndi iron oxide ndi zinthu zina.Kusiyanaku kwazinthu zapakati kumabweretsa mikhalidwe yosiyanasiyana ya transformer ndi magwiridwe antchito.
Mmodzi mwa ubwino waukulu waamorphous pachimakethiransifoma ndi awo kwambiri yafupika pachimake zomvetsa.Kutayika kwapakati kumatanthawuza mphamvu zomwe zimatayika mu transformer core, zomwe zimapangitsa mphamvu zowonongeka komanso kuwonjezeka kwa kutentha.Poyerekeza ndi ma ferrite cores, ma amorphous cores amakhala ndi ma hysteresis otsika kwambiri komanso kuwonongeka kwapakali pano, zomwe zimapangitsa kuti pakhale kutentha kwambiri komanso kutentha kwapang'onopang'ono.Kuwongolera bwino kwa 30% mpaka 70% poyerekeza ndi zosinthira wamba kumapangitsa zosintha za amorphous core kukhala njira yokongola yamakampani opulumutsa mphamvu.
Kuphatikiza apo, ma amorphous cores ali ndi maginito abwino kwambiri, kuphatikiza kuchuluka kwachulukidwe kwamphamvu.Kuchuluka kwa maginito kuchulukirachulukira kumatanthawuza kuchuluka kwa maginito komwe zinthu zapakati zimatha kutengera.Ma amorphous alloys ali ndi kachulukidwe kachulukidwe kakang'ono poyerekeza ndi ma ferrite cores, kulola kuti ma transfoma ang'onoang'ono, opepuka komanso kachulukidwe kake kawonjezeke.Ubwinowu ndi wopindulitsa makamaka kwa ntchito zomwe kukula kwake ndi zolemetsa ndizofunika kwambiri, monga magetsi amagetsi, machitidwe opangira mphamvu zowonjezera komanso magalimoto amagetsi.
Ubwino wina wa ma amorphous core transformers ndikuchita bwino kwambiri pafupipafupi.Chifukwa cha mawonekedwe ake apadera a atomiki, ma amorphous alloys amawonetsa kutayika kwapakatikati pama frequency apamwamba, kuwapangitsa kukhala abwino kugwiritsa ntchito zomwe zikukhudzana ndi kuchepetsa mphamvu yamagetsi yamagetsi (EMI) kuchepetsa.Makhalidwewa amathandizira ma amorphous core transformers kuti athetse bwino phokoso la EMI, potero amathandizira kudalirika kwadongosolo ndikuchepetsa kusokoneza kwa zida zamagetsi zamagetsi.
Ngakhale zabwino izi,amorphous pachimakema transfoma ali ndi malire.Choyamba, mtengo wa ma amorphous alloys ndi apamwamba kuposa zida za ferrite, zomwe zimakhudza mtengo woyambira wa thiransifoma.Komabe, kupulumutsa mphamvu kwanthawi yayitali komwe kumachitika chifukwa cha kuchuluka kwa magwiridwe antchito nthawi zambiri kumalipira mtengo wokwera woyamba.Chachiwiri, makina a amorphous alloys nthawi zambiri amakhala otsika poyerekeza ndi ma ferrite cores, zomwe zimawapangitsa kukhala okhudzidwa kwambiri ndi kupsinjika kwamakina komanso kuwonongeka komwe kungachitike.Kulingalira koyenera kwa mapangidwe ndi njira zogwirira ntchito ndizofunika kwambiri kuti zitsimikizire kuti moyo wautali ndi wodalirika wa amorphous core transformers.
Mwachidule, ma amorphous core transformers ali ndi zabwino zambiri kuposa zosinthira zachikhalidwe za ferrite.Kuwonongeka kwawo kocheperako, kuchita bwino kwambiri kwa maginito, magwiridwe antchito apamwamba kwambiri, komanso kukula kochepa ndi kulemera kwake kumawapangitsa kukhala chisankho chokongola pamagwiritsidwe osiyanasiyana.Pamene kufunikira kwa machitidwe ogwiritsira ntchito mphamvu kumapitirira kukula, ma amorphous core transformers akuyenera kukhala ndi gawo lofunikira pokwaniritsa zofunikirazi ndikuyendetsa mafakitale ku tsogolo lobiriwira, lokhazikika.
