ʻO ka mahana Curie o ke kumu transformer

"I kekahi manawa i hala aku nei, ua nīnau kekahi inā loaʻa i ka magnetic core kahi pae pale wela. A pane mai kekahi penei:

'O ka papa kū'ai wela no nā mea ho'olale. ʻAʻole i manaʻo ʻia ke kumu magnetic he mea insulating, no laila ʻaʻohe ona kikoʻī kūʻē i ka wela. Akā, loaʻa iā ia kahi ʻāpana pili i ka wela i kapa ʻiaKa wela o ka Curie.'

I kēia lā, e kamaʻilio kākou e pili ana i ka 'Ka wela o ka Curie' o ke kumu magnetic.

ʻO ka mahana Curie, ʻike ʻia hoʻi ʻo ka Curie point a i ʻole ka helu hoʻololi magnetic, ʻo ia ka manawa e hāʻule ai ka ikaika o ke kahua magnetic o ka mea i ka 0 i ka wā i wela ai. Ua ʻike ʻia ʻo ia e nā Curies i ka hopena o ke kenekulia 19: ke hoʻomehana ʻoe i ka magnet i kahi mahana, e nalowale kona magnetism mua.

I nā mea hoʻololi (nā mea hoʻokomo), ina kapuʻupuʻu magnetic'O ka wela ma luna o kona Curie wela, hiki ke kumu i ka inductance e hāʻule i ka 0. Oiai ka hapanui o nā huahana hiki ke hoʻihoʻi hou i kā lākou hana ma hope o ka hoʻoluʻu ʻana, no nā mea hoʻololi (inductors) i ka hana, me ka loaʻa ʻole o ka inductance e alakaʻi i ka hāʻule ʻole a me ke ahi.

No laila i ka hoʻolālā ʻana a me ke koho ʻananā mea hoʻololi(inductors), he mea nui e waiho i kekahi palena no ka mālama ʻana i ka mahana o ka mea magnetic ma lalo o kāna kiko Curie i ka wā e hana ai.

ʻO ka mahana Curie o ka mana manganese-zinc ferrite ma luna o 210 ° C. ʻO ka hapa nui o nā mea insulation transformer (inductor) he haʻahaʻa haʻahaʻa ma mua o kēia, no laila i ka wā o ka hana ʻana, ʻaʻole hiki i ka magnetic core ke hiki i nā wela kiʻekiʻe.

ʻO ka mahana Curie o ke kiʻekiʻe-conductivity manganese-zinc ferrite ma luna o 110 ° C. Hiki i ka hapa nui o ka transformer (inductor) insulation mea ke mālama i nā mahana kiʻekiʻe ma mua o kēia, a ʻo ka mahana o ka transformer (inductor) ma hope o ka hana hiki ke maʻalahi ma luna o kēia. No laila, pono mākou e makaʻala i ke ʻano o kā mākou hoʻolālā ʻana i nā cores magnetic conductivity kiʻekiʻe e hōʻoia i ka wela loa ke hoʻohana ʻia.

ʻO ka mahana Curie o ka nickel-zinc ferrite ma luna o 100 ° C. E like me ka ferrite kiʻekiʻe-conductivity, he mea koʻikoʻi loa ia e hōʻoia ʻaʻole e wela ke kumu magnetic ma mua o ka mahana Curie i ka wā e hana ana ka transformer (inductor). He mea koʻikoʻi kēia no kā mākou huahana nickel-zinc i hoʻohana mau ʻia, e like me nā mea hoʻokomo ʻano I-like, nā mea hoʻokomo koʻokoʻo, a me nā inductors toroidal nickel-zinc.

ʻOi aku ka mahana o ka Curie o ka alloy powder core ma luna o 450 ℃, he kiʻekiʻe loa. I kēia hihia, pono mākou e makaʻala e pili ana i ka maikaʻi o nā mea ʻē aʻe o ka transformer (inductor) hiki ke mālama i ka wela.

No ka Pūnaewele kēia ʻatikala a no kāna mea kākau mua.
