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.Iialloyi ze-Amorphous zinezinga eliphezulu lokuxinana koxinzelelo xa kuthelekiswa neecores ze-ferrite, ezivumela iinguqu ezincinci, ezilula kunye nokwanda koxinzelelo lwamandla.Olu ncedo luluncedo ngokukhethekileyo kwizicelo apho ubukhulu kunye nobunzima bobunzima bubaluleke kakhulu, njengamandla ombane, 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 zomatshini ze-amorphous alloys ngokuqhelekileyo zingaphantsi kwezo ze-ferrite cores, zibenza bachaphazeleke ngakumbi kuxinzelelo lomatshini 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.
