Kwindawo yobunjineli bombane kunye nokuhanjiswa kwamandla, ukukhethwa kwezinto eziphambili ze-transformers kunye ne-inductors zidlala indima ebalulekileyo ekunqumeni ukusebenza kakuhle kunye nokusebenza kwezixhobo.Izinketho ezimbini ezidumileyo zezinto eziphambili ziyi-amorphous core kunye ne-nanocrystalline core, nganye inika iipropati ezizodwa kunye neenzuzo.Kweli nqaku, siza kukhangela kwiimpawu ze-amorphous core kunye ne-nanocrystalline core, kwaye sihlolisise umahluko phakathi kwezi zimbini.
Yintoni iAmorphous Core?
An i-amorphous coreluhlobo lwezinto ezingundoqo ezinozibuthe ezibonakala ngolwakhiwo lweathom engeyiyo icrystalline.Olu lungelelwaniso lukhethekileyo lweathom lunika ii-amorphous cores iipropathi zazo ezahlukileyo, kubandakanya ilahleko esezantsi engundoqo, ukungeneka okuphezulu, kunye neempawu ezibalaseleyo zemagnethi.Izinto eziqhelekileyo ezisetyenziselwa i-amorphous cores yi-alloy-based alloy, ehlala iqulethe izinto ezifana nentsimbi, i-boron, i-silicon kunye ne-phosphorus.
Ubume obungeyona i-crystalline ye-amorphous cores kubangela ukucwangciswa okungahleliwe kwee-athomu, ezithintela ukubunjwa kwemimandla yamagnetic kunye nokunciphisa ilahleko zangoku ze-eddy.Oku kwenza ukuba i-amorphous cores isebenze ngokufanelekileyo kwizicelo apho ukulahleka kwamandla aphantsi kunye nokugqithiswa kwemagneti kubaluleke kakhulu, njengakwi-transformers yokuhambisa amandla kunye ne-inductors ephezulu-frequency.
I-amorphous cores yenziwa ngokusebenzisa inkqubo yokuqinisa ngokukhawuleza, apho i-alloy etyhidiweyo icinywa kwizinga eliphezulu kakhulu lokuthintela ukubunjwa kwezakhiwo ze-crystalline.Le nkqubo iphumela kwisakhiwo se-athomu esingenalo ulandelelwano olude, lunika izinto eziphathekayo iimpawu zayo ezizodwa.
Yintoni iNanocrystalline Core?
Ngakolunye uhlangothi, i-nanocrystalline core luhlobo lwe-matrical core material equkethe i-nanometer-sized crystalline grains efakwe kwi-matrix ye-amorphous.Esi sakhiwo sesigaba sesibini sidibanisa izibonelelo zombini zecrystalline kunye ne-amorphous materials, ezikhokelela kwiipropati ezigqwesileyo zamagnetic kunye ne-saturation flux density.
Iintsimbi zeNanocrystallineziqhele ukwenziwa ngokudityaniswa kwentsimbi, nickel, kunye necobalt, kunye nezongezo ezincinci zezinye izinto ezinje ngobhedu kunye nemolybdenum.Isakhiwo se-nanocrystalline sibonelela ngokugqithiswa kwamagnetic, ukunyanzeliswa okuphantsi, kunye nokuzinza okuphezulu kwe-thermal, okwenza kube yinto efanelekileyo kwizicelo zamandla aphezulu kunye nabaguquli be-high-frequency transformers.
Umahluko phakathi kweAmorphous Core kunye neNanocrystalline Core
Umahluko ophambili phakathi kwe-amorphous cores kunye ne-nanocrystalline cores ilele kwisakhiwo sabo se-athomu kunye nesiphumo seempawu zemagneti.Ngelixa i-amorphous cores ine-non-crystalline structure ngokupheleleyo, i-nanocrystalline cores ibonisa isakhiwo sesigaba sesibini esiquka i-nanometer-sized crystalline grains ngaphakathi kwe-amorphous matrix.
Ngokweempawu zemagnethi,i-amorphous coresziyaziwa ngokulahleka kwazo okuphantsi kunye nokungena okuphezulu, okwenza ukuba zilungele izicelo apho ukufaneleka kwamandla kubaluleke kakhulu.Kwelinye icala, ii-nanocrystalline cores zibonelela ngoxinzelelo oluphezulu lwe-saturation flux kunye nokuzinza okuphezulu kwe-thermal, kubenza bafanelekele usetyenziso lwamandla aphezulu kunye ne-high-frequency application.
Omnye umahluko ophambili yinkqubo yokuvelisa.I-amorphous cores iveliswa ngokuqiniswa ngokukhawuleza, okubandakanya ukucima i-alloy etyhidiweyo kwizinga eliphezulu lokuthintela ukubunjwa kwe-crystalline.Ngokwahlukileyo, ii-nanocrystalline cores ziqhele ukwenziwa ngokufakwa kunye nokulawulwa kwecrystallization yeeribhoni ze-amorphous, okukhokelela ekwenziweni kweenkozo zekristale ezinobungakanani be-nanometer ngaphakathi kwemathiriyeli.
Iingqwalasela zeSicelo
Xa ukhetha phakathi kwee-amorphous cores kunye ne-nanocrystalline cores kwisicelo esithile, izinto ezininzi kufuneka ziqwalaselwe.Ukusetyenziswa kwezicelo ezibeka phambili ukulahlekelwa kwamandla aphantsi kunye nokusebenza okuphezulu, njengakwi-transformers yokusabalalisa amandla kunye ne-high-frequency inductors, ii-amorphous cores zihlala zikhethwa ngokukhethekileyo.Ilahleko yabo ephantsi engundoqo kunye nokugqithiswa okuphezulu kubenza bafaneleke ngokufanelekileyo kwezi zicelo, bafake isandla ekugcinweni kwamandla ngokubanzi kunye nokusebenza okuphuculweyo.
Ngakolunye uhlangothi, kwizicelo ezifuna ukuxinana okuphezulu kwe-saturation flux, ukuzinza okuphezulu kwe-thermal, kunye nokukwazi ukuphatha amandla aphezulu, ii-nanocrystalline cores zifanelekile ngakumbi.Ezi zakhiwo zenza i-nanocrystalline cores ilungele ii-high-power transformers, usetyenziso lwe-inverter, kunye nokunikezelwa kwamandla okujikeleza okuphezulu, apho ukukwazi ukuphatha uxinano oluphezulu lwemagnethi kunye nokugcina uzinzo phantsi kweemeko zokusebenza ezahlukeneyo kubalulekile.
Ukuqukumbela, zombini ii-amorphous cores kunye ne-nanocrystalline cores zibonelela ngeenzuzo ezizodwa kwaye zilungelelaniswe kwiimfuno ezithile zesicelo.Ukuqonda umahluko kwisakhiwo sabo se-athomu, iipropathi zemagneti, kunye neenkqubo zokuvelisa kubalulekile ukwenza izigqibo ezinolwazi xa ukhetha izinto eziphambili zeenguqu kunye nee-inductors.Ngokusebenzisa iimpawu ezahlukileyo zemathiriyeli nganye, iinjineli kunye nabayili banokunyusa ukusebenza kunye nokusebenza kakuhle kokuhanjiswa kwamandla abo kunye neenkqubo zokuguqula, ekugqibeleni zibe negalelo kwinkqubela phambili ekusebenzeni kakuhle kwamandla kunye nokugcinwa kobuchwepheshe bamandla.
