Kedu uru na ọghọm dị na cores amorphous alloy cores eji na-emepụta amorphous alloy core transformers
Amorphous ihe niile ihe onwunwe bụ ụdị ihe alloy ọhụrụ pụtara na 1970s. Ọ na-anakwere teknụzụ jụrụ oyi ngwa ngwa nke mba ụwa iji mee ka igwe mmiri dị jụụ ozugbo na ọnụego jụrụ oyi nke 106 Celsius C/S iji mepụta eriri siri ike nke nwere ọkpụrụkpụ nke 0.02-0.03mm. Ọ gbasiri ike tupu ya enwee ike kristal. Ihe alloy yiri iko na nhazi atọm oge niile, na-enweghị usoro kristal nke ọla, na ihe ndị bụ isi ya bụ ígwè (Fe), nickel (Ni), cobalt (Co), silicon (Si), boron (B) , carbon (C) wdg. Ihe ya nwere uru ndị a:
a) Nke amorphous ihe alloy enweghị usoro kristal ma bụrụ ihe ndọta dị nro isotropic; ike magnetization dị ntakịrị ma nwee ezigbo nkwụsi ike okpomọkụ. Ebe ọ bụ na amorphous alloy bụ ihe na-abụghị nke gbakwasara agbawa, kpọmkwem seaming nwere ike iji mee ka usoro nke n’ichepụta ígwè isi dịtụ mfe;
b) Enweghị ntụpọ nhazi nke na-egbochi mmegharị nke ngalaba magnetik, na ọnwụ hysteresis dị ntakịrị karịa nke mpempe akwụkwọ silicon;
c) Ọkpụrụkpụ nke warara dị oke mkpa, naanị 0.02-0.03mm, nke bụ ihe dịka 1/10 nke mpempe akwụkwọ silicon.
d) The resistivity dị elu, ihe dị ka ugboro atọ nke nke ọka-gbakwasara n’ubi silicon ígwè Ibé akwụkwọ; na eddy ugbu a ọnwụ nke amorphous alloy ihe na-ukwuu ebelata, ya mere unit ọnwụ bụ banyere 20% ka 30% nke ọka-gbakwasara n’elu silicon ígwè Ibé akwụkwọ;
e) The annealing okpomọkụ dị ala, ihe dị ka 1/2 nke ọka-gbakwasara silica ígwè mpempe akwụkwọ;
Ọrụ enweghị ibu nke isi ihe alloy amorphous dị elu. Ọnwụ na-enweghị ibu nke transformer mere nke amorphous alloy core bụ 70-80% dị ala karịa nke mgbanwe mgbanwe, na enweghị ibu ugbu a na-ebelata karịa 50%. Mmetụta na-azọpụta ike pụtara ìhè. N’ihi na ebumnobi nke mbenata netwọk ahịrị ọnwụ, ma State Grid na China Southern Power Grid nwere ukwuu ụba procurement ruru nke amorphous alloy transformers kemgbe 2012. Ka ọ dị ugbu a, nkezi nke procurement nke amorphous alloy nkesa transformers nwere ihu ọma ruru ihe karịrị 50%.
Amorphous alloy transformers nwekwara ọghọm ndị a:
1) Njupụta magnetik saturation dị ala. Njupụta magnetik saturation nke amorphous alloy core na-abụkarị ihe dịka 1.56T, nke bụ ihe dịka 20% dị iche na njupụta magnetik saturation 1.9T nke mpempe akwụkwọ silicon nkịtị. Ya mere, njupụta magnetik emebere nke transformer kwesịkwara ibelata 20%. Njupụta njupụta njupụta mmanụ kristal alloy na-adịkarị n’okpuru 1.35T, yana njupụta njupụta nke amorphous alloy akọrọ igwe na-adịkarị n’okpuru 1.2T.
2) Mkpokọta amorphous isi warara na-enwe mmetụta maka nrụgide. Mgbe a kpasuru eriri isi ahụ, arụmọrụ enweghị ibu dị mfe ịka njọ. Ya mere, ekwesịrị itinye nlebara anya pụrụ iche na nhazi ahụ. Ekwesịrị ịkwụsị isi ya na etiti nkwado na eriri igwe, na ihe niile bụ naanị Ọ na-eburu ike ndọda ya. N’otu oge ahụ, ekwesịrị ịkwụ ụgwọ nlebara anya pụrụ iche n’oge usoro mgbakọ ahụ. Enweghị ike idobe isi ígwè ahụ n’ike, na ịkụ aka kwesịrị ibelata.
3) Magnetostriction dị ihe dị ka 10% karịa nke mpempe akwụkwọ silicon a na-ahụkarị, ya mere mkpọtụ ya na-esiri ike ịchịkwa, nke bụkwa otu n’ime isi ihe kpatara na-egbochi mgbasawanye mgbasa ozi nke amorphous alloy transformers. Mkpọtụ nke ihe ntụgharị na-ebute ihe ndị dị elu dị elu, nke kewara n’ime ebe ndị nwere mmetụta na mpaghara ndị na-adịghị emetụ n’ahụ, a na-etinyekwa ọkwa ọkwa ụda kpọmkwem, nke na-achọ n’ihu mbelata nke isi imewe flux njupụta.
4) The amorphous alloy strip dị ntakịrị ntakịrị, yana ọkpụrụkpụ nke naanị 0.03mm, yabụ enweghị ike ịme ya ka ọ bụrụ lamination dị ka mpempe ọla silicon nkịtị, mana enwere ike ịme ya ka ọ bụrụ ihe mkpuchi. Ya mere, ndị na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-enweghị ike ịhazi ya n’onwe ha, ma na-achọkarị Outsourcing n’ozuzu ya, kwekọrọ na akụkụ akụkụ anọ nke ọnyá isi ọnya, a na-emekarị eriri igwe nke amorphous alloy transformer ka ọ bụrụ akụkụ anọ;
5) Ogo nke localization ezughị. Ka ọ dị ugbu a, ọ bụ ọkpọkọ amorphous alloy na-ebubata site na Hitachi Metals, nke na-eji nwayọọ nwayọọ na-achọpụta mpaghara. N’ime ụlọ, Antai Technology na Qingdao Yunlu nwere brọdband amorphous alloy (213mm, 170mm na 142mm). , na arụmọrụ ya ka bụ ụfọdụ oghere na nkwụsi ike ma e jiri ya tụnyere ibe ndị ebubata.
6) Oke kachasị ogologo ogologo nke warara, ogologo eriri mpụta nke mbụ amorphous alloy strip na-ejedebe site nha nke ọkụ ọkụ na-ekpo ọkụ, na ogologo ya na-egbochikwa nke ukwuu, mana edozila ya ugbu a, yana alloy amorphous. na a kacha elu peripheral warara ogologo nke 10m nwere ike na-emepụta The isi etiti nwere ike iji rụpụta 3150kVA na n’okpuru amorphous alloy akọrọ mgbanwe na 10000kVA na n’okpuru amorphous alloy mmanụ mgbanwe.
Dabere na mmetụta dị mma na-azọpụta ike nke amorphous alloy transformers, tinyere nkwalite nke nchekwa nchekwa ike mba na mbelata ikuku na usoro atumatu, òkè ahịa nke amorphous alloy transformers na-abawanye. Ọzọkwa, na-atụle amorphous alloy strip (ugbu a 26.5 yuan / kg) bụ ihe dị ka okpukpu abụọ nke ot silicon ígwè Ibé akwụkwọ (30Q120 ma ọ bụ 30Q130), na ọdịiche na ọla kọpa dịtụ obere. N’ịtụle ịdị mma nke ngwaahịa grid na ihe achọrọ, ihe ntụgharị alloy amorphous na-ejikarị ndị nduzi ọla kọpa. N’iji ya na mpempe akwụkwọ ígwè silicon nkịtị, nnukwu ọdịiche dị ọnụ ala nke amorphous alloy transformers bụ ndị a:
1) Ebe ọ bụ na a nakweere ihe nhazi nke ọnya ahụ, ụdị ihe ntụgharị ahụ kwesịrị ịnakwere usoro nke atọ nke akụkụ ise, nke nwere ike ibelata ịdị arọ nke otu-frame isi ma belata ihe isi ike nke mgbakọ. Usoro nke kọlụm ise nke atọ na akụkụ atọ nke akụkụ atọ nwere uru na ọghọm ha n’ihe gbasara ọnụ ahịa Ka ọ dị ugbu a, ọtụtụ ndị na-emepụta ihe na-eji usoro atọ nke ise.
2) Ebe ọ bụ na akụkụ obe nke isi kọlụm bụ akụkụ anọ, iji nọgide na-enwe nkwekọ nke anya mkpuchi ahụ, a na-eme ka eriri voltaji dị elu na nke dị ala na-eme ka ọ bụrụ akụkụ anọ kwekọrọ.
3) Ebe ọ bụ na njupụta magnetik nke isi imewe bụ banyere 25% ala karịa nke omenala silicon ígwè mpempe akwụkwọ transformers, na ya isi lamination ọnụọgụ bụ banyere 0.87, nke bụ nnọọ ala karịa 0.97 nke ot silicon ígwè mpempe akwụkwọ transformers, imewe cross- Mpaghara mpaghara kwesịrị ibu karịa nke ndị na-agbanwe mpempe akwụkwọ silicon ígwè. Ọ bụrụ na ọ kariri 25% buru ibu, okirikiri nke mkpuchi elu na obere voltaji ga-abawanye kwa ya. N’otu oge ahụ, ọ dị mkpa ka a tụlee mmụba nke ogologo ogologo nke elu na obere voltaji. Iji hụ na nfu nke eriri igwe anaghị agbanwe agbanwe, mpaghara cross-section nke waya kwesịrị ịdị n’otu aka ahụ, ọnụ ọgụgụ ọla kọpa ejiri na amorphous alloy transformers bụ ihe dịka 20% karịa nke ndị na-agbanwe agbanwe.
