Xa kuthelekiswa neetransformer zesiqhelo zeferrite core, iitransformer ze-amorphous core zifumene ingqalelo enkulu kwiminyaka yakutshanje ngenxa yokwakheka kwazo okwahlukileyo kunye nokusebenza okuphuculweyo. Ezi transformers zenziwe ngezinto ezikhethekileyo zemagnethi ezibizwa ngokuba yi-amorphous alloy, ezineempawu ezikhethekileyo ezenza ukuba zibe lolona khetho lokuqala kwiintlobo ngeentlobo zezicelo. Kweli nqaku, siza kuhlola ukuba yintoni kanye kanye i-amorphous core, sigxininise umahluko phakathi kweetransformer ze-amorphous core kunye neetransformer ze-ferrite core, kwaye sixoxe ngeengenelo zokusebenzisa.umbindi ongenamofuabaguquli.
Ngoko ke, yintoni i-amorphous magnetic core? Ii-amorphous magnetic cores zenziwe yimicu emincinci ye-alloy eyenziwe ngezinto ezahlukeneyo zesinyithi, ezihlala ziquka i-iron njengeyona nto iphambili kunye nomxube we-boron, i-silicon, kunye ne-phosphorus. Ngokungafaniyo nezinto zekristale kwii-ferrite cores, ii-athomu kwii-amorphous alloys azibonisi isakhiwo se-atomic esiqhelekileyo, yiyo loo nto zibizwa ngokuba yi-"amorphous." Ngenxa yolu lungiselelo lwe-atomic lukhethekileyo, ii-amorphous cores zineempawu zemagnethi ezibalaseleyo.
Umahluko obalulekileyo phakathi kwee-amorphous core kunye nee-ferrite core transformers zizinto zazo eziphambili. Ii-Amorphous cores zisebenzisa ii-amorphous alloys ezikhankanyiweyo apha ngasentla, ngelixa ii-ferrite cores zenziwe ngee-ceramic compounds eziqulethe i-iron oxide kunye nezinye izinto. Lo mahluko kwizinto eziphambili uphumela kwiimpawu ezahlukeneyo ze-transformer kunye nokusebenza.
Enye yezona nzuzo ziphambili zeumbindi ongenamofuIitransformers zilahleko zazo eziphambili ezinciphileyo kakhulu. Ukulahleka kwecore kubhekisa kumandla achithekileyo kwi-transformer core, nto leyo ebangela ukuchithwa kwamandla kunye nokwanda kokuveliswa kobushushu. Xa kuthelekiswa nee-ferrite cores, ii-amorphous cores zine-hysteresis ephantsi kakhulu kunye nokulahleka kwe-eddy current, nto leyo ebangela ukusebenza kakuhle okuphezulu kunye nobushushu obuphantsi bokusebenza. Ukuphuculwa kokusebenza kakuhle kwe-30% ukuya kwi-70% xa kuthelekiswa neetransformers eziqhelekileyo kwenza ii-amorphous core transformers zibe lukhetho olukhangayo kwishishini lokonga amandla.
Ukongeza, ii-cores ezi-amorphous zineempawu ezintle zemagnethi, kuquka i-saturation flux density ephezulu. I-saturation magnetic flux density ibhekisa kwi-magnetic flux ephezulu enokuthathwa zizinto eziphambili. Ii-alloys ze-Amorphous zinoxinano oluphezulu lwe-saturation flux xa kuthelekiswa nee-ferrite cores, nto leyo evumela ii-transformers ezincinci, ezikhaphukhaphu kunye ne-power density eyonyukileyo. Le nzuzo iluncedo ngakumbi kwizicelo apho ubukhulu kunye nemida yobunzima ibaluleke kakhulu, njenge-electronics yamandla, iinkqubo zamandla avuselelekayo kunye nezithuthi zombane.
Enye inzuzo yee-transformers ze-core ezingenanto kukusebenza kwazo okuphezulu kakhulu. Ngenxa yesakhiwo sazo se-atomic esahlukileyo, ii-alloys ze-amorphous zibonisa ukulahleka okuphantsi kwe-core kwii-frequency eziphezulu, nto leyo eyenza ukuba zilungele ukusetyenziswa okubandakanya ukunciphisa ukuphazamiseka kwe-electromagnetic interference (EMI). Olu phawu luvumela ii-transformers ze-core ezingenanto ukuba zicinezele ngokufanelekileyo ingxolo ye-EMI, ngaloo ndlela ziphucula ukuthembeka kwenkqubo kwaye zinciphise ukuphazamiseka kwizixhobo ze-elektroniki ezinobuthathaka.
Nangona ezi zibonelelo,umbindi ongenamofuIitransformer zinemida ethile. Okokuqala, ixabiso lee-alloys ezi-amorphous liphezulu kunezixhobo ze-ferrite, nto leyo echaphazela iindleko zotyalo-mali lokuqala lwetransformer. Nangona kunjalo, ukonga amandla kwexesha elide okufunyenwe ngokusebenza kakuhle kudla ngokuhlawulela iindleko zokuqala eziphezulu. Okwesibini, iipropati ze-mechanical ze-alloys ezi-amorphous ngokubanzi ziphantsi kunezo ze-ferrite cores, nto leyo eyenza ukuba zibe sesichengeni soxinzelelo lwe-mechanical kunye nomonakalo onokubakho. Iingqwalasela ezifanelekileyo zoyilo kunye neendlela zokucubungula zibalulekile ekuqinisekiseni ukuba iitransformer ezi-amorphous core zihlala ixesha elide kwaye zithembekile.
Ngamafutshane, ii-transformers ze-amorphous core zineengenelo ezininzi kunee-transformers ze-ferrite core zemveli. Ukulahleka kwazo okuncinci kwe-core, ukusebenza okuphezulu kwemagnethi, ukusebenza okuphezulu kwe-frequency ephezulu, kunye nobukhulu obuncinci kunye nobunzima kuzenza zibe lukhetho olunomtsalane kwiintlobo ngeentlobo zezicelo. Njengoko imfuno yeenkqubo ezisebenzisa amandla kakuhle iqhubeka ikhula, ii-transformers ze-amorphous core zinokudlala indima ebalulekileyo ekuhlangabezaneni nezi mfuno kunye nokuqhuba amashishini ukuya kwikamva eliluhlaza nelizinzileyo.
