Chiyambi
Kwa zaka zambiri, ma transformer cores akhala akupangidwa ndi chitsulo cha silicon. Chimagwira ntchito bwino pa 50 kapena 60 Hz. Koma ma solid state transformers (SSTs) sagwira ntchito pa grid frequency - amathamanga pa Hz zikwi makumi ambiri. Pa ma frequency amenewo, kutayika kwa eddy current kwa silicon steel kumakhala kwakukulu kwambiri. Aloyi ya Amorphous ndi yabwino, koma imalepherabe pakati pa ma frequency pomwe ma SST amagwira ntchito.
Nanocrystalline alloy ili pamalo omwe awiriwa amakumana. Imapereka mphamvu zambiri zolowera, kutayika kochepa kwa ma core, komanso kuchuluka kwa madzi ochulukirapo kuposa 1.5 T. Koma ikukumananso ndi zovuta zazikulu. Monga momwe wowonera wina wamakampani adanenera: "Aliyense amene angathe kuthana ndi mavuto omwe akugwiritsidwa ntchito pakali pano a nanocrystalline alloy adzakhala pamwamba pa zida zamagetsi zam'badwo wotsatira".
Malo Ofunika: Chifukwa Chake Miyezo Yakale Sikugwiranso Ntchito
Chitsulo cha silicon chimagwira ntchito pa 50 Hz. Chikankhireni ku 10 kHz, ndipo kutayika kwa eddy current kumawonjezeka. Aloyi ya Amorphous imayendetsa bwino 1–10 kHz, koma kutayika kwake kumakwera mofulumira kuposa pamenepo. Ferrite imagwira ntchito pama frequency apamwamba kwambiri, koma kuchuluka kwake kwa saturation flux kuli pansi pa 0.5 T, zomwe zimapangitsa kuti ma cores akhale akulu kwambiri pakugwiritsa ntchito mphamvu zambiri.
Nanocrystalline alloy imapereka mulingo wosiyana. Imathandiza kuchepetsa kutayika kwa core kwa 40–70% poyerekeza ndi chitsulo cha silicon, ndi kuchuluka kwa saturation flux pamwamba pa 1.5 T ndi coercivity pansi pa 10 A/m. Mu 20–30 kHz - ma frequency amakono a SST - mphamvu ya nanocrystalline imaposa 99%.
"Nanocrystalline alloy ndiye chinthu chofunikira kwambiri pa ma transformer olimba," adatero Zhang Hua, Mlembi Wamkulu wa Amorphous Alloy Materials Application Branch ya China Electrical Equipment Industry Association, pa Msonkhano Wachiwiri wa SST Industry Development mu Epulo 2026.
Mabotolo Anayi Omwe Akubwezeretsa Nanocrystalline
Ngakhale kuti ili ndi ubwino wake, nanocrystalline ikukumana ndi mavuto anayi othandiza omwe achepetsa kugwiritsa ntchito kwake.
Kutayika kwa ma frequency ambiri kudakali ndi mwayi woti kukonzedwe.Pa 50 kHz ndi 0.2 T, kutayika kwa nanocrystalline kuli bwino kuposa kusasinthika koma kumaphatikizapo gawo lalikulu la kutayika konse kwa dongosolo. Riboni woonda kwambiri (14 μm ndi pansi) wakhala malire ampikisano - riboni wa 12 μm ukhoza kuchepetsa kutayika pakati, koma pamtengo wokwera.
Kupanga ndi kukonza n'kovuta.Nanocrystalline alloy ndi yopyapyala, zomwe zimapangitsa kuti kupanga ma core akuluakulu kukhale kovuta kwambiri. Ma SST amphamvu kwambiri amafunika zidutswa zingapo za ma core kuti zilumikizane pamodzi, ndipo kukonza mpweya pamalo olumikizirana kumakhalabe vuto lalikulu.
Kukhazikika kwa kutentha ndi kochepa.Denga lotentha la ntchito ndi 105–120°C. Ngakhale kuti ndi labwino kuposa ferrite, kuchuluka kwa madzi m'thupi kumawolabe kutentha kwambiri. Ma SST amphamvu kwambiri nthawi zambiri amakhala ndi kutentha kochepa, zomwe zimapangitsa kuti kutentha kukhale kotentha kwambiri komwe kumawononga kwambiri magwiridwe antchito a zinthu.
Phokoso la pafupipafupi kwambiri ndi vuto.Nanocrystalline ili ndi mphamvu yocheperako ya maginito kuposa amorphous, koma imagwedezekabe ndipo imapanga phokoso pa ma frequency apamwamba. Epoxy impregnation nthawi zambiri imagwiritsidwa ntchito kulimbitsa pakati ndikuchepetsa phokoso.
Kupatula mavuto awa, pali mavuto atatu omwe amapitirirabe.
Kuchulukana kwa madzi ogwirira ntchito kuyenera kuchepetsedwa kwambiri.Nanocrystalline ili ndi kuchuluka kwa madzi okwanira pafupifupi 1.2 T, koma pa 50 kHz, malire a kapangidwe kake amatsika kufika pa 0.25–0.35 T yokha. Imapitirira 0.35 T, ndipo kutayika kwa ma core kukwera, zomwe zimapangitsa kutentha kwa hotspot kukhala kosalamulirika.
Kuwerengera kutayika kwa ma frequency ambiri n'kovuta.Pa ma frequency apamwamba, nanocrystalline imawonetsa zotsatira zovuta zosagwirizana ndi mzere monga ma currents a inter strip eddy ndi kutayika kwa mphamvu. Mawerengedwe a chiphunzitso amasiyana kwambiri ndi magwiridwe antchito enieni; kuyerekezera kwa zinthu zochepa kokha pamodzi ndi kuyesa kwa prototype kumapereka deta yodalirika.
Kapangidwe ka zotetezera kutentha kumakhala kovuta pakakhala magetsi ambiri komanso ma frequency ambiri.Kupeza mphamvu ya 20 kV yodzipatula pamene ikugwira ntchito pa 50 kHz square wave voltage kumabweretsa chiopsezo chachikulu cha kutulutsa madzi pang'ono. Mtunda wodumphadumpha uyenera kupitirira 32 mm ndipo mtunda wotuluka uyenera kupitirira 16 mm - wokha womwe umadya pafupifupi 40% ya voliyumu ya chipangizocho. Nanocrystalline core iyeneranso kukhala ndi silinda ya polyimide ya 0.2 mm ndikutsekedwa ndi silicone yophimba.
Msika ndi Mwayi
Panganoli ndi lalikulu. Mu 2025, msika wa zinthu zofewa zamaginito ku China (kuphatikizapo zipangizo) unadutsa RMB 30 biliyoni. Gawoli likukula mofulumira kuposa gawo lina lililonse la zinthu zofewa zamaginito, zomwe zimapangitsa kuti pakhale msika woposa 50% padziko lonse lapansi. Malinga ndi zomwe zanenedweratu ndi makampani, zinthu zofewa zamaginito ndi zofewa zamaginito zidzapanga ma "mamiliyoni mazana ambiri a yuan" m'zaka 5-10 zikubwerazi.
Pa mlingo wopanga, makampani ena aku China afika kale pamlingo waukulu. Wopanga wina tsopano akupanga riboni ya 14 μm yopyapyala kwambiri, yokhala ndi mphamvu ya pachaka ya matani 3,000 ndi pulojekiti ya matani 10,000 yomwe ikumangidwa. Ma nanocrystalline cores a Cloudroad achepetsa mphamvu ya transformer ya ma frequency ambiri kufika pa gawo limodzi mwa magawo khumi kuposa ya zinthu wamba, zomwe zapangitsa kuti mphamvu yamagetsi ikhale 11.2 kW/L komanso mphamvu ya 99.6%.
Kumbali ya mfundo, Ndondomeko Yoyendetsera Ntchito Yopangira Zida Zogwiritsa Ntchito Mphamvu Mwapamwamba (2026–2028), yomwe idaperekedwa limodzi ndi maunduna anayi mu Marichi 2026, idalemba momveka bwino ma SST okhala ndi mphamvu zambiri ngati ukadaulo wolimbikitsa patsogolo. Bungwe la China Electrical Equipment Industry Association layambitsanso kulemba miyezo yamagulu ya zipangizo za nanocrystalline zomwe zimagwiritsidwa ntchito mu SST cores.
Mapeto
Chitsulo cha silicon chatha. Amorphous ndi yabwino, koma si yoyenera kugwiritsidwa ntchito pa ma frequency apakati omwe ma SST amagwira ntchito. Nanocrystalline ndiye chinthu chokhacho chomwe chimaphatikiza kuchuluka kwa ma flux, kutayika kochepa kwa ma core, komanso kutseguka kwakukulu pama frequency ofunikira.
Koma "zapamwamba kwambiri" ndi "zothandiza pamalonda" ndi zinthu ziwiri zosiyana. Mpaka mavuto anayi - kutayika kwa ma frequency ambiri, kuvutika kwa kukonza, kukhazikika kwa kutentha, ndi phokoso - zitathetsedwa mwadongosolo, nanocrystalline idzakhalabe chinthu chodalirika m'malo mogwira ntchito yotsimikizika. Monga momwe Zhang Hua adanenera, njira yopitira patsogolo imafuna kusintha kuchoka pa mpikisano wotsika kupita ku chitukuko chokhazikika komanso chokhazikika pazatsopano.
Mpikisano ukuyamba. Funso silili ngati nanocrystalline ingathe kusunga makampani a SST okwana madola mabiliyoni ambiri. Funso ndi lakuti: ndani adzayamba kuswa zopingazo, ndipo zitenga nthawi yayitali bwanji?
