Poyerekeza ndi ma transformer achikhalidwe a ferrite core, ma transformer a amorphous core alandiridwa kwambiri m'zaka zaposachedwa chifukwa cha kapangidwe kawo kapadera komanso magwiridwe antchito abwino. Ma transformer awa amapangidwa kuchokera ku chinthu chapadera cha maginito chotchedwa amorphous alloy, chomwe chili ndi mawonekedwe apadera omwe amachipangitsa kukhala chisankho choyamba pa ntchito zosiyanasiyana. M'nkhaniyi, tifufuza zomwe kwenikweni amorphous core ndi, kuwonetsa kusiyana pakati pa ma transformer a amorphous core ndi ma transformer a ferrite core, ndikukambirana za ubwino wogwiritsa ntchito.pachimake chosapanga mawonekedwema transformer.
Kodi maziko a maginito a amorphous ndi chiyani? Magawo a maginito a amorphous amakhala ndi timizere tating'onoting'ono topangidwa ndi zinthu zosiyanasiyana zachitsulo, zomwe nthawi zambiri zimaphatikizapo chitsulo ngati chinthu chachikulu komanso kuphatikiza kwa boron, silicon, ndi phosphorous. Mosiyana ndi zinthu zoyera zomwe zili mu ferrite cores, maatomu omwe ali mu alloys a amorphous sawonetsa kapangidwe ka atomu kokhazikika, motero amatchedwa "amorphous." Chifukwa cha dongosolo lapadera la atomuli, magawo a amorphous ali ndi mphamvu zabwino kwambiri zamaginito.
Kusiyana kwakukulu pakati pa ma transformer a amorphous core ndi ma ferrite core ndi zinthu zawo zapakati. Ma cores a amorphous amagwiritsa ntchito ma alloys a amorphous omwe atchulidwa pamwambapa, pomwe ma ferrite cores amapangidwa kuchokera ku zinthu za ceramic zomwe zili ndi iron oxide ndi zinthu zina. Kusiyana kumeneku kwa zinthu zapakati kumabweretsa mawonekedwe ndi magwiridwe antchito osiyanasiyana a transformer.
Chimodzi mwa zabwino zazikulu zapachimake chosapanga mawonekedweMa transformer ndi kutayika kwawo kwapakati komwe kumachepa kwambiri. Kutayika kwapakati kumatanthauza mphamvu zomwe zimatayika mu transformer core, zomwe zimapangitsa kuti mphamvu ziwonongeke komanso kutentha kuchuluke. Poyerekeza ndi ma ferrite core, ma amorphous core ali ndi hysteresis yochepa kwambiri komanso kutayika kwa eddy current, zomwe zimapangitsa kuti ntchito ikhale yogwira ntchito bwino komanso kutentha kotsika. Kuwonjezeka kwa magwiridwe antchito a 30% mpaka 70% poyerekeza ndi ma transformer wamba kumapangitsa ma amorphous core transformer kukhala njira yokopa makampani osunga mphamvu.
Kuphatikiza apo, ma cores a amorphous ali ndi mphamvu zabwino kwambiri zamaginito, kuphatikizapo kuchuluka kwa ma flux a saturation. Kuchuluka kwa maginito a saturation kumatanthauza kuchuluka kwa maginito komwe zinthu zapakati zimatha kukhala nako. Ma alloys a amorphous ali ndi kuchuluka kwa ma flux a saturation poyerekeza ndi ma cores a ferrite, zomwe zimapangitsa kuti ma transformer ang'onoang'ono, opepuka komanso kuchuluka kwa mphamvu. Ubwino uwu ndi wopindulitsa makamaka pakugwiritsa ntchito komwe zoletsa kukula ndi kulemera ndizofunikira kwambiri, monga zamagetsi zamagetsi, makina obwezeretsanso mphamvu ndi magalimoto amagetsi.
Ubwino wina wa ma transformer a amorphous core ndi ntchito yawo yapamwamba kwambiri ya ma frequency apamwamba. Chifukwa cha kapangidwe kawo kapadera ka atomu, ma alloy a amorphous amawonetsa kutayika kochepa kwa ma core pama frequency apamwamba, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito kuphatikiza kusokoneza kwa ma electromagnetic interference (EMI) kwa ma frequency apamwamba. Khalidweli limalola ma transformer a amorphous core kuletsa bwino phokoso la EMI, motero kumawonjezera kudalirika kwa makina ndikuchepetsa kusokoneza kwa zida zamagetsi zomwe zimakhala zovuta.
Ngakhale zabwino zonsezi,pachimake chosapanga mawonekedweMa transformer ali ndi zofooka zina. Choyamba, mtengo wa ma alloy osasinthika ndi wokwera kuposa zipangizo za ferrite, zomwe zimakhudza mtengo woyambira wa transformer. Komabe, kusunga mphamvu kwa nthawi yayitali komwe kumachitika chifukwa cha kuchuluka kwa mphamvu nthawi zambiri kumalipira mtengo woyambira wokwera. Chachiwiri, mphamvu zamakina za ma alloy osasinthika nthawi zambiri zimakhala zochepa poyerekeza ndi za ma cores a ferrite, zomwe zimapangitsa kuti zikhale zosavuta kupsinjika ndi kuwonongeka komwe kungachitike. Kuganizira bwino kapangidwe kake ndi njira zogwirira ntchito ndizofunikira kwambiri kuti zitsimikizire kuti ma transformer osasinthika amakhala ndi moyo wautali komanso wodalirika.
Mwachidule, ma transformer a amorphous core ali ndi ubwino wambiri kuposa ma transformer achikhalidwe a ferrite core. Kutayika kwawo kochepa kwa core, mphamvu ya maginito yapamwamba, magwiridwe antchito abwino kwambiri, komanso kukula kochepa ndi kulemera kumawapangitsa kukhala chisankho chokopa pa ntchito zosiyanasiyana. Pamene kufunikira kwa machitidwe osagwiritsa ntchito mphamvu zambiri kukupitirira kukula, ma transformer a amorphous core mwina adzachita gawo lofunika kwambiri pakukwaniritsa zofunikira izi ndikuyendetsa mafakitale ku tsogolo lobiriwira komanso lokhazikika.
