Amorphous alloy izinto luhlobo olutsha lwemathiriyeli yealloyi eyaphuma ngeminyaka yoo-1970. Yamkela ubuchwephesha bokupholisa obuphezulu behlabathi obukhawulezayo bokupholisa ngokuthe ngqo isinyithi elulwelo ngesantya sokupholisa esingu-106°C/S ukwenza umcu obhityileyo oqinileyo onobunzima obuyi-0.02-0.03mm. Yaqina ngaphambi kokuba ikhazimle. Izinto ze-alloy zifana neglasi kwilungiselelo le-athomu elingaqhelekanga, ngaphandle kwesakhiwo se-crystal esibonakaliswe yintsimbi, kunye nezinto zayo ezisisiseko ziyintsimbi (Fe), i-nickel (Ni), i-cobalt (Co), i-silicon (Si), i-boron (B) , ikhabhoni (C) njl. Izinto zayo zineenzuzo ezilandelayo:

a) I iamorphous I-alloy material ayinayo i-crystal structure kwaye i-isotropic soft magnetic material; amandla emagneti mancinci kwaye inozinzo oluhle lobushushu. Ukususela kwi iamorphous I-alloy yinto engajoliswanga, ukuthunga ngokuthe ngqo kunokusetyenziswa ukwenza inkqubo yokwenziwa kwentsimbi ibe lula;

b) Akukho ziphene zesakhiwo ezithintela ukuhamba kwemimandla yamagnetic, kwaye ilahleko ye-hysteresis incinci kune-silicon sheet sheets;

c) Ubukhulu bomtya buncinci kakhulu, kuphela yi-0.02-0.03mm, malunga ne-1/10 ye-silicon sheet sheet.

d) I-resistivity iphezulu, malunga namaxesha amathathu amatye e-silicone-oriented-oriented silicon; ilahleko yangoku ye-eddy yezinto ze-amorphous alloy iyancipha kakhulu, ngoko ke ilahleko yeyunithi malunga ne-20% ukuya kwi-30% yeeshiti zensimbi ze-silicon;

e) Ubushushu be-annealing buphantsi, malunga ne-1/2 ye-silicone yentsimbi yentsimbi;

Ukusebenza komthwalo we-amorphous alloy core kuphezulu. Ilahleko engenamthwalo we-transformer eyenziwe ye-amorphous alloy core yi-70-80% ephantsi kune-transformer eqhelekileyo, kwaye akukho mthwalo wangoku uyancipha ngaphezu kwe-50%. Isiphumo sokugcina amandla sibalaseleyo. Ngenjongo yokunciphisa ilahleko yomgca womnatha, zombini i-State Grid kunye ne-China Southern Power Grid ziye zandisa kakhulu umlinganiselo wokuthengwa kwee-amorphous alloy transformers ukususela ngo-2012. Okwangoku, umlinganiselo wokuthengwa kwe-amorphous alloy distribution transformers uye wafikelela ngokusisiseko ngaphezu kwe-50%.

Iziguquli ze-amorphous alloy nazo zineziphene zilandelayo:

I-1) Uxinzelelo lwemagnethi lokugcwala luphantsi. Ukuxinana kwemagnethi ye-amorphous alloy core ngokuqhelekileyo malunga ne-1.56T, emalunga ne-20% eyahlukileyo kwi-1.9T yoxinaniso lwemagnethi ye-silicon yentsimbi yesiqhelo. Ngoko ke, ukuxinana kwamagnetic okwenzelwe i-transformer kufuneka kuncitshiswe ngama-20%. Ubuninzi be-design flux ye-crystal alloy transformer idla ngokuba ngaphantsi kwe-1.35T, kunye ne-design flux density ye-amorphous alloy dry transformer idla ngokuba ngaphantsi kwe-1.2T.

2) Uluhlu olupheleleyo lwe-amorphous core luvakalelwa kuxinzelelo. Emva kokuba umtya ongundoqo ugxininiswe, ukusebenza ngokungekho mthwalo kulula ukuwohloka. Ngoko ke, ingqalelo ekhethekileyo kufuneka ihlawulwe kwisakhiwo. Ingundoqo kufuneka inqunyanyiswe kwisakhelo senkxaso kunye nekhoyili, kwaye yonke into kuphela Ithwala ubunzima bayo. Ngelo xesha, ingqalelo ekhethekileyo kufuneka ihlawulwe ngexesha lenkqubo yendibano. Undoqo wentsimbi awunakunyanzelwa, kwaye ukunkqonkqoza kufuneka kuncitshiswe.

I-3) I-Magnetostriction imalunga ne-10% enkulu kunaleyo ye-silicone sheet sheets yentsimbi, ngoko ke ingxolo yayo inzima kakhulu ukuyilawula, ekwayenye yezizathu eziphambili ezinciphisa ukukhuthazwa okubanzi kwee-amorphous alloy transformers. Ingxolo ye-transformer ibeka phambili iimfuno eziphezulu, ezahlulahlulwe kwiindawo ezinobuthathaka kunye neendawo ezingabonakaliyo, kunye neemfuno ezicacileyo zenqanaba lesandi zibekwe phambili, ezifuna ukuncitshiswa ngakumbi kwe-core design flux density.

4) Uluhlu lwe-amorphous alloy luncinci, lunobunzima obuyi-0.03mm kuphela, ngoko ke alunakwenziwa kwi-laminations njengamashidi ensimbi ye-silicon eqhelekileyo, kodwa inokwenziwa kuphela kwii-cores ezidibeneyo. Ngoko ke, abavelisi besiqhelo be-transformer besakhiwo esingundoqo abanakukwazi ukuyiqhuba ngokwabo, kwaye ngokuqhelekileyo bafuna i-Outsourcing iyonke, ehambelana necandelo le-rectangular le-strip core strip, i-coil ye-amorphous alloy transformer idla ngokuphinda yenziwe ibe yisakhiwo soxande;

I-5) Iqondo lendawo yokuhlala alanele. Okwangoku, ubukhulu becala ngumgca we-amorphous alloy othathwe kumazwe angaphandle kwi-Hitachi Metals, ethi ngokuthe ngcembe iqonde indawo yokuhlala. Ekhaya, i-Antai Technology kunye neQingdao Yunlu zine-amorphous alloy broadband (213mm, 170mm kunye ne-142mm). , kwaye ukusebenza kwayo kusengumsantsa othile kuzinzo xa kuthelekiswa nemicu evela kumazwe angaphandle.

6) Owona mda wobude bomcu uphezulu, obona bude buphezulu beperipheral strip bomcu wokuqala we-amorphous alloy strip bukhawulelwe ngubungakanani besithando somlilo, kwaye ubude baso buthintelwe kakhulu, kodwa sele kusonjululwe ngoku, kunye nealloy amorphous. kunye nobuninzi be-peripheral strip ubude obuyi-10m bunokuveliswa Isakhelo esingundoqo singasetyenziselwa ukuvelisa i-3150kVA kwaye ngaphantsi kwe-amorphous alloy utshintsho olomileyo kunye ne-10000kVA kwaye ngaphantsi kwe-amorphous alloy alloy change.

Ngokusekelwe kwisiphumo esihle kakhulu sokugcina amandla e-amorphous alloy transformers, kunye nokukhuthazwa kokugcinwa kwamandla elizwe kunye nokunciphisa ukukhutshwa kunye noluhlu lwemigaqo-nkqubo, isabelo semarike ye-amorphous alloy transformers iyanda. Ngaphezu koko, ukuqwalasela umcu we-amorphous alloy strip (okwangoku yi-26.5 yuan / kg) malunga nokuphindwe kabini kunamashiti ensimbi ye-silicon eqhelekileyo (30Q120 okanye 30Q130), kwaye isithuba esinobhedu sincinci. Ukuqwalasela umgangatho weemveliso zegridi kunye neemfuno zebhidi, abaguquli be-amorphous alloy ngokuqhelekileyo basebenzisa abaqhubi bobhedu. Xa kuthelekiswa namaphepha entsimbi ye-silicon eqhelekileyo, izithuba eziphambili zeendleko ze-amorphous alloy transformers zilandelayo:

I-1) Ekubeni i-core core structure yamkelwa, uhlobo oluphambili lwe-transformer lufanele lwamkele isakhiwo sekholomu yesigaba sesithathu, esinokunciphisa ubunzima besiseko esisodwa kunye nokunciphisa ubunzima bokuhlanganisana. Isigaba sesithathu sesigaba se-five-column kunye nesigaba sesithathu sekholamu ezintathu zineenzuzo zabo kunye nokungalunganga ngokweendleko Okwangoku, abaninzi abavelisi bamkela isigaba sesithathu sekholamu yesihlanu.

2) Ekubeni i-cross-section of the core column i-rectangular, ukwenzela ukuba kugcinwe ukuhambelana komgama we-insulation, ii-coil high and low voltage coil nazo zenziwe kwisakhiwo esihambelanayo soxande.

3) Ekubeni ubuninzi bemagnethi yoyilo olungundoqo bumalunga ne-25% ngaphantsi kunesiguquli sentsimbi ye-silicon yesiqhelo, kwaye i-coefficient yayo ye-lamination engundoqo imalunga ne-0.87, engaphantsi kakhulu kune-0.97 ye-silicone yentsimbi yesiguquli seshidi, uyilo olunqamlezayo- indawo yecandelo kufuneka ibe nkulu kuneyo yesiqhelo i-silicon steel sheet transformers. Ukuba ingaphezulu kwe-25% enkulu, i-circumference ye-coil ephezulu kunye ne-low voltage coil nayo iya kwanda ngokufanelekileyo. Ngexesha elifanayo, ukunyuka kobude beekhoyili eziphezulu kunye nezisezantsi kufuneka kuqwalaselwe. Ukuqinisekisa ukuba ukulahleka komthwalo we-coil akutshintshi, indawo enqamlekileyo yocingo kufuneka ihambelane ngokuhambelanayo, ubuninzi bobhedu obusetyenziselwa i-amorphous alloy transformers malunga ne-20% ngaphezu kwe-transformers eqhelekileyo.
