Xa kuthelekiswa neziguquli ezingundoqo ze-ferrite, iziguquli ezingundoqo ze-amorphous zifumene ingqalelo enkulu kwiminyaka yakutshanje ngenxa yokwakheka kwazo okwahlukileyo kunye nokusebenza okuphuculweyo. Ezi ziguquli zenziwe kwizinto ezikhethekileyo zamagnetic ezibizwa ngokuba yi-amorphous alloy, eneempawu ezikhethekileyo ezenza kube yinto yokuqala yokukhetha kwizicelo ezahlukeneyo. Kweli nqaku, siza kuphonononga ukuba yintoni kanye i-amorphous core, siqaqambise umahluko phakathi kwe-amorphous core transformers kunye ne-ferrite core transformers, kwaye sixoxe ngezinto eziluncedo zokusebenzisai-amorphous coreiinguqu.
Ke, yintoni i-amorphous magnetic core? I-Amorphous magnetic cores iqulathe imicu yealloyi ebhityileyo eyenziwe ngezinto ezahlukeneyo zentsimbi, ezibandakanya intsimbi njengeyona nto iphambili kunye nendibaniselwano yeboron, isilicon, kunye nephosphorus. Ngokungafaniyo ne-crystalline material in ferrite cores, ii-athomu kwii-alloys ze-amorphous azibonisi isakhiwo se-athomu esiqhelekileyo, ngoko ke igama elithi "amorphous." Ngenxa yolu lungiselelo lukhethekileyo lweathom, ii-amorphous cores zineempawu ezibalaseleyo zemagnethi.
Owona mahluko ubalulekileyo phakathi kwe-amorphous core kunye ne-ferrite core transformers zizinto zabo eziphambili. Iintsimbi ze-amorphous zisebenzisa i-alloys ye-amorphous ekhankanywe ngasentla, ngelixa i-ferrite cores yenziwe kwi-ceramic compounds equkethe i-iron oxide kunye nezinye izinto. Lo mahluko kwizinto ezingundoqo uphumela kwiimpawu ezahlukeneyo ze-transformer kunye nokusebenza.
Enye yeenzuzo eziphambili zei-amorphous coreii-transformers yilahleko yazo esezantsi kakhulu. Ilahleko engundoqo ibhekisela kumandla achithwayo kwi-transformer core, okukhokelela kumandla achithwayo kunye nokwanda kokuveliswa kobushushu. Xa kuthelekiswa ne-ferrite cores, i-amorphous cores ine-hysteresis ephantsi kakhulu kunye nelahleko yangoku ye-eddy, okukhokelela ekusebenzeni okuphezulu kunye nokushisa okuphantsi kokusebenza. Ukuphuculwa kobuchule be-30% ukuya kwi-70% xa kuthelekiswa neziguquli eziqhelekileyo zenza i-amorphous core transformers ibe yinto ekhangayo kwishishini lokonga amandla.
Ukongeza, ii-amorphous cores zineempawu ezigqwesileyo zemagneti, kubandakanya noxinzelelo oluphezulu lwe-saturation. Uxinzelelo lwemagnethi yosasazo lubhekiselele kobona tshintsho luphezulu lwemagnethi enokumelana nemathiriyeli engundoqo. I-amorphous alloys inoxinzelelo oluphezulu lwe-saturation flux xa kuthelekiswa neecores ze-ferrite, ezivumela iinguqu ezincinci, ezikhaphukhaphu kunye nokwanda koxinzelelo lwamandla. Olu ncedo lunenzuzo ngokukodwa kwizicelo apho ubukhulu kunye nobunzima bobunzima bubaluleke kakhulu, njengombane wamandla, iinkqubo zamandla avuselelekayo kunye nezithuthi zombane.
Olunye uncedo lwe-amorphous core transformers kukusebenza kwabo okuphezulu okuphezulu. Ngenxa yobume bazo obukhethekileyo beathom, iialloyi zeamorphous zibonisa ilahleko esezantsi engundoqo kumaza aphezulu, zizenza zilungele usetyenziso olubandakanya uphazamiseko lwe-high-frequency electromagnetic (EMI) . Olu phawu lwenza ukuba i-amorphous core transformers icinezele ngokufanelekileyo ingxolo ye-EMI, ngaloo ndlela iphucula ukuthembeka kwenkqubo kunye nokunciphisa ukuphazamiseka kwizixhobo ze-elektroniki ezinovakalelo.
Ngaphandle kwezi nzuzo,i-amorphous coreiziguquli zinemida ethile. Okokuqala, iindleko ze-amorphous alloys ziphezulu kunezixhobo ze-ferrite, ezichaphazela iindleko zokuqala zokutshala imali kwi-transformer. Nangona kunjalo, ugcino lwamandla lwexesha elide oluphunyeziweyo ngokwandisa ukusebenza kakuhle luhlala luhlawulela iindleko eziphezulu zokuqala. Okwesibini, iipropathi zemishini ye-amorphous alloys ngokuqhelekileyo zingaphantsi kwezo ze-ferrite cores, ezenza kube lula ukuxinzezeleka komatshini kunye nomonakalo onokwenzeka. Iingqwalasela ezifanelekileyo zoyilo kunye nobuchule bokucubungula zibalulekile ekuqinisekiseni ixesha elide kunye nokuthembeka kwee-amorphous core transformers.
Isishwankathelo, iziguquli ezingundoqo ze-amorphous zineenzuzo ezininzi ngaphezu kweenguqu ezingundoqo ze-ferrite. Ilahleko yabo encitshisiweyo engundoqo, ukusebenza kwemagnethi ephezulu, ukusebenza okuphezulu okuphezulu okuphezulu, kunye nobukhulu obuncinci kunye nobunzima bubenza babe lukhetho olunomtsalane kwiintlobo ezahlukeneyo zezicelo. Njengoko imfuno yeenkqubo zokusetyenziswa kwamandla iqhubeka ikhula, i-amorphous core transformers inokuthi idlale indima ebalulekileyo ekuhlangabezaneni nezi mfuno kunye nokuqhuba amashishini ukuya kwikamva eliluhlaza, elizinzileyo.
