Amorphous alloy Boitsebiso ke mofuta o mocha oa lisebelisoa tsa alloy tse ileng tsa tsoa ka bo-1970. E amohela theknoloji e tsoetseng pele ea machaba ea ho pholisa ka potlako ho pholile ka ho toba tšepe e nang le metsi ka sekhahla sa ho pholisa sa 106°C/S ho etsa lesela le tiileng le tšesaane le botenya ba 0.02-0.03mm. E ile ea tiea pele e ka khanya. Thepa ea alloy e tšoana le khalase ka tlhophiso e sa tloaelehang ea athomo, ntle le sebopeho sa kristale se khetholloang ke tšepe, ‘me likarolo tsa eona tsa motheo ke tšepe (Fe), nickel (Ni), cobalt (Co), silicon (Si), boron (B) , carbon (C) joalo-joalo Thepa ea eona e na le melemo e latelang:

a) The fetohile lisebelisoa tsa alloy ha li na sebopeho sa kristale ebile ke lisebelisoa tse bonolo tsa isotropic; matla a magnetization a nyane mme a na le botsitso bo botle ba mocheso. Ho tloha ka fetohile alloy ke thepa e sa sekametseng, ho roka ka ho toba ho ka sebelisoa ho etsa hore mokhoa oa ho etsa motheo oa tšepe o be bonolo;

b) Ha ho na mefokolo ea sebopeho e sitisang ho tsamaea ha libaka tsa makenete, ‘me tahlehelo ea hysteresis e nyane ho feta ea lishiti tsa tšepe tsa silicon;

c) Botenya ba sekhahla bo tšesaane haholo, ke 0.02-0.03mm feela, e ka bang 1/10 ea letlapa la tšepe la silicon.

d) Ho hanyetsa ho phahame, hoo e ka bang ka makhetlo a mararo ho feta a maqephe a tšepe a silicon a nang le lijo-thollo; tahlehelo ea hona joale ea eddy ea lisebelisoa tsa amorphous alloy e fokotsehile haholo, kahoo tahlehelo ea yuniti e ka bang 20% ​​ho isa ho 30% ea lishiti tsa tšepe tsa silicon tse sekametseng lijo-thollo;

e) Thempereichara ea annealing e tlase, hoo e ka bang 1/2 ea pampiri ea tšepe ea silicon e sekametseng lijo-thollo;

Ts’ebetso e se nang moroalo oa mantlha ea amorphous alloy e phahame. Tahlehelo e se nang moroalo oa sesebelisoa se entsoeng ka motsoako oa amorphous alloy ke 70-80% e tlase ho feta ea transformer e tloaelehileng, ‘me hona joale ha ho na mojaro o fokotsehile ka ho feta 50%. Phello ea ho boloka matla e ikhetha. Bakeng sa ho fokotsa tahlehelo ea mohala oa marang-rang, bobeli ba State Grid le China Southern Power Grid ba eketsehile haholo karo-karolelano ea theko ea li-amorphous alloy transformers ho tloha ka 2012. Hona joale, karolo ea theko ea li-amorphous alloy distribution transformers e fihlile ho feta 50%.

Li-amorphous alloy transformer le tsona li na le mefokolo e latelang:

1) The saturation magnetic density e tlase. The saturation magnetic density ea amorphous alloy core hangata e ka ba 1.56T, e ka bang 20% ​​e fapaneng le 1.9T saturation magnetic density ea letlapa le tloaelehileng la silicon. Ka hona, matla a khoheli a entsoeng ka motlakase le ona a hloka ho fokotsoa ka 20%. Moralo oa flux density ea crystal alloy oil transformer hangata e ka tlase ho 1.35T, mme sebopeho sa flux density ea amorphous alloy dry transformer hangata e ka tlase ho 1.2T.

2) Karolo ea mantlha ea amorphous e na le maikutlo a khatello ea maikutlo. Kamora hore sekhahla sa mantlha se hateletsoe, ts’ebetso ea ho se be le moroalo e bonolo ho senyeha. Ka hona, tlhokomelo e khethehileng e lokela ho lefshoa mohahong. Konokono e lokela ho emisoa holim’a foreimi ea tšehetso le khoele, ‘me kaofela ke eona feela E jere matla a eona a khoheli. Ka nako e ts’oanang, tlhokomelo e khethehileng e lokela ho lefshoa nakong ea ts’ebetso ea kopano. Moko oa tšepe o ke ke oa etsoa ka matla, ‘me ho kokota ho lokela ho fokotsoa.

3) Magnetostriction ke hoo e ka bang 10% e kholoanyane ho feta ea lishiti tsa tšepe tse tloaelehileng tsa silicon, kahoo lerata la eona le thata ho laola, e leng le leng la mabaka a ka sehloohong a fokotsang ho phatlalatsoa ho pharaletseng ha li-amorphous alloy transformers. Lerata la transformer le fana ka litlhoko tse phahameng, tse arotsoeng ka libaka tse tebileng le libaka tse sa tsotelleng, ‘me litlhoko tse khethehileng tsa boemo ba molumo li behiloe pele, tse hlokang ho fokotseha ho eketsehileng ha moralo oa mantlha oa flux density.

4) Letlapa la amorphous alloy le batla le le tšesaane, le na le botenya ba 0.03mm feela, kahoo le ke ke la etsoa ka li-laminations joaloka maqephe a tloaelehileng a tšepe ea silicon, empa le ka etsoa feela ka li-cores tse kopantsoeng. Ka hona, bahlahisi ba tloaelehileng ba li-transformer tsa sebopeho sa mantlha ba ke ke ba e sebetsana ka bobona, ‘me hangata ba hloka Outsourcing ka kakaretso, e tsamaellanang le karolo ea khutlonnetsepa ea leqeba la mokokotlo oa mokokotlo, mokelikeli oa amorphous alloy transformer hangata o boetse o etsoa ka sebopeho sa kgutlonne;

5) Tekanyo ea sebaka sa libaka ha ea lekana. Hajoale, haholo-holo ke lesela la amorphous alloy le tsoang kantle ho naha ho tsoa ho Hitachi Metals, leo butle-butle le hlokomelang sebaka sa lehae. Ka lapeng, Antai Technology le Qingdao Yunlu li na le amorphous alloy broadband (213mm, 170mm le 142mm). , ‘me ts’ebetso ea eona e ntse e le lekhalo le itseng la botsitso ha le bapisoa le lihlopha tse tsoang linaheng tse ling.

6) Tekanyo e phahameng ea bolelele ba strip, bolelele bo boholo ba peripheral strip ea pele ea amorphous alloy strip e lekantsoe ke boholo ba sebōpi sa annealing, ‘me bolelele ba eona le bona bo thibetsoe haholo, empa bo se bo rarollotsoe hona joale, le motsoako oa amorphous. le palo e kahodimodimo peripheral hlobolisa bolelele ba 10m ka hlahiswa The foreime ea mantlha e ka sebelisoa ho etsa 3150kVA le ka tlase amorphous alloy dry change le 10000kVA le ka tlase amorphous alloy oil change.

Ho ipapisitsoe le phello e ntle ea ho boloka matla ea li-amorphous alloy transformer, hammoho le ho khothaletsa paballo ea matla a naha le phokotso ea mosi le letoto la maano, karolo ea ‘maraka ea li-amorphous alloy transformer e ntse e eketseha. Ho feta moo, ha ho nahanoa ka lesela la motsoako oa amorphous (hona joale 26.5 yuan / kg) ke hoo e ka bang habeli ho feta ea maqephe a tloaelehileng a silicon (30Q120 kapa 30Q130), ‘me lekhalo le nang le koporo le batla le le lenyenyane. Ha ho nahanoa ka boleng ba lihlahisoa tsa marang-rang le litlhoko tsa ho reka, li-amorphous alloy transformers hangata li sebelisa li-conductor tsa koporo. Ha ho bapisoa le lishiti tsa tšepe tse tloaelehileng tsa silicon, likheo tse kholo tsa litšenyehelo tsa li-amorphous alloy transformer ke tse latelang:

1) Kaha mohaho oa mokokotlo oa leqeba o amohetsoe, mofuta oa mantlha oa transformer o lokela ho amohela sebopeho sa mehala e mehlano ea mekhahlelo e meraro, e ka fokotsang boima ba mokokotlo o le mong le ho fokotsa bothata ba kopano. Mohaho oa mekhahlelo e meraro ea lihlopha tse hlano le mohaho oa mekhahlelo e meraro ea lihlopha tse tharo li na le melemo le melemo ea tsona ho ea ka litšenyehelo Hona joale, bahlahisi ba bangata ba sebelisa mekhoa e meraro ea mekhahlelo e mehlano.

2) Kaha karolo e ka holimo ea mokoloko oa mantlha e na le mahlakore a mabeli, e le ho boloka botsitso ba sebaka sa ho kenya letsoho, li-coil tse phahameng le tse tlaase li boetse li etsoa hore e be sebopeho se lumellanang le mahlakore a mabeli.

3) Kaha matla a khoheli a moralo oa mantlha a ka tlase ho 25% ho feta a li-transformer tse tloaelehileng tsa silicon, ‘me coefficient ea eona ea mantlha e ka bang 0.87, e tlase haholo ho feta 0.97 ea li-transformer tse tloaelehileng tsa silicon. sebaka sa likarolo se hloka ho ba seholo ho feta sa li-transformer tse tloaelehileng tsa silicon. Haeba e feta 25% e kholoanyane, selikalikoe sa li-coil tsa motlakase tse phahameng le tse tlaase le tsona li tla eketseha ho latela. Ka nako e ts’oanang, ho eketseha ha bolelele ba li-coil tse phahameng le tse tlaase ho boetse ho lokela ho nkoa. Ho etsa bonnete ba hore tahlehelo ea moroalo oa coil ha e fetohe, sebaka sa sefapano sa terata se lokela ho ba Ka mokhoa o ts’oanang, palo ea koporo e sebelisoang li-amorphous alloy transformers e ka bang 20% ​​ho feta ea li-transformers tse tloaelehileng.
