High Permeability Nanocrystalline C pachimake

Kulowetsedwa kwamphamvu kwa maginito: kuchulukitsa kwa maginito Bs = 1.2T, komwe kuli kowirikiza kawiri kwa permalloy ndi 2.5 kuchulukitsa kwa ferrite.Kuchuluka kwamphamvu kwachitsulo chachitsulo ndi chachikulu, chomwe chimatha kufika 15 kW mpaka 20 kW / kg.

Zida za nanocrystalline zilinso ndi zabwino zachitsulo cha silicon, permalloy, ndi ferrite.chomwe chiri:

1. Kulowetsedwa kwamphamvu kwa maginito: kuchulukitsa kwa maginito Bs = 1.2T, komwe kuli kawiri kawiri ka permalloy ndi 2.5 nthawi ya ferrite.Kuchuluka kwamphamvu kwachitsulo chachitsulo ndi chachikulu, chomwe chimatha kufika 15 kW mpaka 20 kW / kg.
2. High permeability: The poyamba malo amodzi permeability μ0 akhoza kukhala mkulu monga 120,000 kuti 140,000, amene ali ofanana permalloy.Kuthekera kwa maginito kwapakati pachitsulo cha thiransifoma yamagetsi kumapitilira nthawi 10 kuposa ferrite, zomwe zimachepetsa kwambiri mphamvu yachisangalalo ndikuwongolera magwiridwe antchito a thiransifoma.
3. Kutayika kochepa: pafupipafupi 20kHz mpaka 50kHz, ndi 1/2 mpaka 1/5 ya ferrite, yomwe imachepetsa kutentha kwapakati pachitsulo.
4. Kutentha kwapamwamba kwa Curie: kutentha kwa Curie kwa zipangizo za nanocrystalline kumafika 570 ℃, ndipo kutentha kwa Curie kwa ferrite ndi 180 ℃~200 ℃.

Chifukwa cha zabwino zomwe tafotokozazi, thiransifoma yopangidwa ndi nanocrystals imagwiritsidwa ntchito pamagetsi osinthira magetsi, omwe athandiza kwambiri pakuwongolera kudalirika kwamagetsi:

1. Kutayika kumakhala kochepa ndipo kutentha kwa transformer kumakhala kochepa.Kugwiritsa ntchito nthawi yayitali kwa ogwiritsa ntchito ambiri kwatsimikizira kuti kutentha kwa nanocrystalline transformer ndikotsika kwambiri kuposa chubu la IGBT.
2. Kuthamanga kwapamwamba kwa maginito achitsulo kumachepetsa mphamvu yosangalatsa, kumachepetsa kutayika kwa mkuwa, komanso kumapangitsa kuti transformer ikhale yabwino.Inductance yoyamba ya transformer ndi yayikulu, yomwe imachepetsa mphamvu yapano pa chubu cha IGBT pakusintha.
3. Kulowetsedwa kwa maginito kumagwira ntchito kwambiri ndipo mphamvu yamagetsi imakhala yochuluka, yomwe imatha kufika 15Kw / kg.Voliyumu yachitsulo yachitsulo imachepetsedwa.Makamaka mphamvu yamagetsi yamagetsi yamagetsi, kutsika kwa voliyumu kumawonjezera malo mu chassis, zomwe zimapindulitsa pakutentha kwa chubu cha IGBT.
4. Kuchuluka kwamphamvu kwa thiransifoma ndikolimba.Popeza ntchito ya maginito inductance imasankhidwa pafupifupi 40% ya machulukitsidwe maginito inductance, pamene kuchulukira kumachitika, kutentha kumangopangidwa chifukwa cha kuchuluka kwa maginito inductance, ndipo chubu cha IGBT sichidzawonongeka chifukwa cha kuchuluka kwa maginito. pachimake chitsulo.
5. Kutentha kwa Curie kwa zipangizo za nanocrystalline ndizokwera kwambiri.Ngati kutentha kumafika pamwamba pa 100 ° C, chosinthira cha ferrite sichingathenso kugwira ntchito, ndipo nanocrystalline transformer ikhoza kugwira ntchito bwino.
Ubwino uwu wa nanocrystalline wazindikirika ndikuvomerezedwa ndi opanga magetsi ochulukirapo.Opanga angapo apakhomo atenga zida zachitsulo za nanocrystalline ndikuzigwiritsa ntchito kwa zaka zambiri.Opanga ambiri ayamba kugwiritsa ntchito kapena kuyesa.Pakali pano, wakhala ankagwiritsa ntchito makina kuwotcherera inverter, magetsi kulankhulana, electroplating ndi electrolytic magetsi, kupatsidwa ulemu Kutentha magetsi, nawuza magetsi ndi madera ena, ndipo padzakhala kuwonjezeka kwambiri zaka zingapo zikubwerazi.

Makhalidwe Antchito

High machulukitsidwe maginito induction mwamphamvu ndi mkulu maginito permeability-mkulu mwatsatanetsatane, mwatsatanetsatane, miniaturization, ndi mkulu linearity wa thiransifoma;
Kukhazikika kwa kutentha kwabwino - kumatha kugwira ntchito pa -55 ~ 120C kwa nthawi yayitali.

1 Kukulitsa kwachulukidwe - kuchepetsedwa kwakukulu kwapakati
2 mawonekedwe amakona anayi - yosavuta kukhazikitsa koyilo
3 Kutayika kwachitsulo chochepa - kukwera kwa kutentha kochepa
4 Kukhazikika kwabwino - kumatha kugwira ntchito mu -20 -150 o C
5 Broadband - 20KHz mpaka 80KHz
6 Mphamvu - 50w mpaka 100kw.
