Kiʻekiʻe Permeability Nanocrystalline C kumu

Loaʻa i nā mea nanocrystalline nā pono o ke kila silika, permalloy, a me ka ferrite.ʻo ia hoʻi:

1. Kiʻekiʻe magnetic induction: ka saturation magnetic induction Bs=1.2T, ʻo ia ka pālua o ka permalloy a me ka 2.5 manawa o ka ferrite.Nui ka mana o ke kumu hao, hiki ke hiki i 15 kW a 20 kW / kg.
2. Kiʻekiʻe permeability: ʻO ka static permeability mua μ0 hiki ke kiʻekiʻe e like me 120,000 a 140,000, e like me ka permalloy.ʻO ka permeability magnetic o ke kumu hao o ka mea hoʻololi mana i ʻoi aku ma mua o 10 mau manawa o ka ferrite, kahi e hoʻemi nui ai i ka mana excitation a hoʻomaikaʻi i ka pono o ka transformer.
3. Haʻahaʻa poho: ma ke alapine o 20kHz a hiki i 50kHz, he 1/2 i ka 1/5 o ka ferrite, e hoemi ana i ka piʻi wela o ke kumu hao.
4. ʻO ka mahana Curie kiʻekiʻe: ʻo ka mahana Curie o nā mea nanocrystalline hiki i 570 ℃, a ʻo ka mahana Curie o ferrite he 180 ℃ ~ 200 ℃ wale nō.

Ma muli o nā pono i luna, hoʻohana ʻia ka mea hoʻololi i hana ʻia i nā nanocrystals i ka mana inverter, kahi i hana nui i ka hoʻomaikaʻi ʻana i ka hilinaʻi o ka mana mana:

1. He liʻiliʻi ka poho a he haʻahaʻa ka piʻi ʻana o ka mahana o ka transformer.ʻO ka hoʻohana lōʻihi lōʻihi o ka nui o nā mea hoʻohana ua hōʻoia i ka piʻi ʻana o ka mahana o ka mea hoʻololi nanocrystalline ma lalo o ka mea o ka paipu IGBT.
2. ʻO ke kiʻekiʻe magnetic permeability o ke kumu hao e hoʻemi i ka mana excitation, hoʻemi i ka poho keleawe, a hoʻomaikaʻi i ka pono o ka transformer.ʻO ka inductance mua o ka transformer he nui, e hōʻemi ana i ka hopena o kēia manawa ma ka paipu IGBT i ka wā e hoʻololi ai.
3. He kiʻekiʻe ka induction magnetic hana a he kiʻekiʻe ka mana o ka mana, hiki ke hiki i 15Kw / kg.Hoʻemi ʻia ka nui o ke kumu hao.ʻOi aku ka mana o ka mana inverter kiʻekiʻe, hoʻonui ka hoʻohaʻahaʻa leo i ka lewa i loko o ka chassis, kahi mea e pono ai i ka hoʻoheheʻe wela o ka paipu IGBT.
4. He ikaika ka overload o ka transformer.No ka mea ua koho ʻia ka inductance magnetic hana ma kahi o 40% o ka saturation magnetic inductance, i ka wā e loaʻa ai ka overload, e hana ʻia ka wela ma muli o ka piʻi ʻana o ka inductance magnetic, a ʻaʻole e pōʻino ka paipu IGBT ma muli o ka saturation o ke kumu hao.
5. He kiʻekiʻe ka mahana Curie o nā mea nanocrystalline.Inā piʻi ka mahana ma luna o 100 ° C, ʻaʻole hiki i ka transformer ferrite ke hana hou, a hiki i ka nanocrystalline transformer ke hana maʻamau.
ʻO kēia mau mea maikaʻi o ka nanocrystalline ua ʻike ʻia a ʻae ʻia e nā mea hana lako mana.Ua hoʻohana kekahi mau mea hana hale i nā core hao nanocrystalline a hoʻohana iā lākou no nā makahiki he nui.Ke hoʻomaka nei nā mea hana hou aʻe e hoʻohana a hoʻāʻo paha.I kēia manawa, ua hoʻohana nui ʻia i ka mīkini wiliwili inverter, ka mana kamaʻilio, ka electroplating a me ka mana electrolytic, ka mana hoʻomehana induction, ka hoʻouka ʻana i ka mana a me nā māla ʻē aʻe, a e piʻi nui aʻe i nā makahiki e hiki mai ana.
