Kwicandelo lobunjineli bombane kunye nokusasazwa kwamandla, ukukhethwa kwezinto eziphambili zeetransformers kunye nee-inductors kudlala indima ebalulekileyo ekumiseleni ukusebenza kakuhle kunye nokusebenza kwezixhobo. Ukhetho oludumileyo lwezinto eziphambili yi-amorphous core kunye ne-nanocrystalline core, nganye ineempawu kunye neenzuzo ezikhethekileyo. Kweli nqaku, siza kujonga iimpawu ze-amorphous core kunye ne-nanocrystalline core, kwaye sihlolisise umahluko phakathi kwezi zimbini.
Yintoni i-Amorphous Core?
An umbindi ongenamofuluhlobo lwezinto ezingundoqo zemagnethi ezibonakaliswa bulwakhiwo lwazo lweathomu olungelulo olwekristale. Olu lungiselelo lukhethekileyo lweathomu lunika ii-cores ezi-amorphous iipropati zazo ezahlukileyo, kubandakanya ukulahleka okuphantsi kwe-core, ukungena okuphezulu, kunye neepropati ezibalaseleyo zemagnethi. Izinto eziqhelekileyo ezisetyenziselwa ii-cores ezi-amorphous yi-alloy esekwe kwisinyithi, edla ngokuqulatha izinto ezifana nesinyithi, i-boron, i-silicon, kunye ne-phosphorus.
Indlela ii-cores ezi-amorphous ezingasebenzi ngayo i-crystalline ibangela ukulungelelaniswa okungacwangciswanga kwee-athomu, nto leyo ethintela ukwakheka kwee-domains ze-magnetic kwaye inciphise ukulahleka kwe-eddy current. Oku kwenza ii-cores ezi-amorphous zisebenze kakuhle kakhulu kwizicelo apho ukulahleka kwamandla aphantsi kunye nokungena kwamandla aphezulu kubalulekile, njengakwii-transformers zokusasazwa kwamandla kunye nee-inductors eziphezulu.
Ii-cores ezi-Amorphous zenziwa kusetyenziswa inkqubo yokuqina ngokukhawuleza, apho i-alloy enyibilikisiweyo icinywa ngesantya esiphezulu kakhulu ukuthintela ukwakheka kwezakhiwo zekristale. Le nkqubo iphumela kwisakhiwo seathomu esingenalo ulungelelwano olude, nto leyo enika izinto iimpawu zaso ezikhethekileyo.
Yintoni iNanocrystalline Core?
Kwelinye icala, i-nanocrystalline core luhlobo lwezinto ze-magnetic core eziqulathe ii-crystalline grains ezinobukhulu be-nanometer ezifakwe kwi-amorphous matrix. Olu lwakhiwo lwe-dual-phase ludibanisa iingenelo zezinto ze-crystalline kunye ne-amorphous, nto leyo ekhokelela kwiipropati ze-magnetic ezibalaseleyo kunye noxinano oluphezulu lwe-saturation flux.
Ii-Nanocrystalline coresNgokwesiqhelo zenziwe ngokudibanisa isinyithi, i-nickel, kunye ne-cobalt, kunye nezinye izinto ezincinci ezifana ne-copper kunye ne-molybdenum. Isakhiwo se-nanocrystalline sinika amandla aphezulu e-magnetic permeability, amandla aphantsi okuqhuba, kunye nozinzo oluphezulu lobushushu, okwenza ukuba ifaneleke kwizicelo zamandla aphezulu kunye nee-transformers ezisebenzisa i-frequency ephezulu.
Umahluko phakathi kwe-Amorphous Core kunye ne-Nanocrystalline Core
Umahluko ophambili phakathi kwee-amorphous cores kunye nee-nanocrystalline cores usekwe kwisakhiwo sazo se-athomu kunye neempawu zemagnethi ezibangelwa yiyo. Ngelixa ii-amorphous cores zinesakhiwo esingesiso se-crystalline ngokupheleleyo, ii-nanocrystalline cores zibonisa isakhiwo se-dual-phase esakhiwe zii-crystalline grains ezinobukhulu be-nanometer ngaphakathi kwe-amorphous matrix.
Ngokuphathelele iipropati zemagnethi,ii-cores ezingenasimozaziwa ngokulahleka kwazo okuphantsi komongo kunye nokuvuleka okuphezulu, nto leyo ezenza zilungele ukusetyenziswa apho ukusebenza kakuhle kwamandla kubaluleke kakhulu. Kwelinye icala, ii-nanocrystalline cores zibonelela ngoxinano oluphezulu lwe-saturation flux kunye nozinzo oluphezulu lobushushu, nto leyo ezenza zifaneleke ukusetyenziswa kwamandla aphezulu kunye namaza amaninzi.
Omnye umahluko ophambili yinkqubo yokuvelisa. Ii-Amorphous cores ziveliswa ngokuqiniswa ngokukhawuleza, okubandakanya ukucima i-alloy enyibilikisiweyo ngesantya esiphezulu ukuthintela ukwakheka kwekristale. Ngokwahlukileyo koko, ii-nanocrystalline cores zihlala ziveliswa ngokuqhoboshelwa kunye nokuqiniswa kwekristale okulawulwayo kweeribhoni ezi-amorphous, okubangela ukwakheka kweenkozo zekristale ezinobukhulu be-nanometer ngaphakathi kwezinto.
Izinto ekufuneka ziqwalaselwe xa kusenziwa isicelo
Xa ukhetha phakathi kwee-cores ezi-amorphous kunye nee-cores ze-nanocrystalline kwisicelo esithile, kufuneka kuqwalaselwe izinto ezininzi. Kwizicelo ezibeka phambili ukulahlekelwa kwamandla aphantsi kunye nokusebenza kakuhle, njengakwii-transformers zokusasazwa kwamandla kunye nee-inductors eziphezulu, ii-cores ezi-amorphous zihlala zikhethwa kakhulu. Ukulahleka kwazo okuphantsi kunye nokungena okuphezulu kwenza ukuba zilungele ezi zicelo, zinegalelo ekongeni amandla ngokubanzi kunye nokusebenza okuphuculweyo.
Kwelinye icala, kwizicelo ezifuna uxinano oluphezulu lwe-flux density, uzinzo oluphezulu lobushushu, kunye nobuchule bokuphatha amandla aphezulu, ii-nanocrystalline cores zifanelekile ngakumbi. Ezi mpawu zenza ii-nanocrystalline cores zilungele ii-transformers ezinamandla aphezulu, izicelo ze-inverter, kunye nezixhobo zamandla ezisebenzisa i-frequency ephezulu, apho ukukwazi ukuphatha uxinano oluphezulu lwe-magnetic flux kunye nokugcina uzinzo phantsi kweemeko zokusebenza ezahlukeneyo kubalulekile.
Ukuqukumbela, zombini ii-cores ezingabonakaliyo kunye nee-nanocrystalline cores zibonelela ngeenzuzo ezikhethekileyo kwaye zenzelwe iimfuno ezithile zesicelo. Ukuqonda umahluko kwisakhiwo sazo se-athomu, iimpawu zemagnethi, kunye neenkqubo zokuvelisa kubalulekile ekwenzeni izigqibo ezinolwazi xa kukhethwa izixhobo eziphambili zee-transformers kunye nee-inductors. Ngokusebenzisa iimpawu ezahlukeneyo zesixhobo ngasinye, iinjineli kunye nabayili banokuphucula ukusebenza kunye nokusebenza kakuhle kweenkqubo zabo zokusasazwa kwamandla kunye nokuguqulwa kwamandla, ekugqibeleni banegalelo ekuphuculeni ukusebenza kakuhle kwamandla kunye nobuchwepheshe bamandla obuzinzileyo.
