Karma Resistance Nichrome Wire no ka Uea Pumehana

ʻO ka wehewehe pōkole:

Karma huila

Hana ʻia ʻo Karma alloy i ke keleawe, nickel, Aluminum a me ka hao ma ke ʻano nui. ʻO ka resistivity he 2 ~ 3 mau manawa kiʻekiʻe ma mua o MENTONG. He haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ke kū'ē (TCR), haʻahaʻa haʻahaʻa EMF me ke keleawe, kūpaʻa maikaʻi o ke kūpaʻa no ka manawa lōʻihi a me ka anti-oxidation ikaika. ʻOi aku ka laulā o kāna hana wela ma mua o MENTONG (-60 ~ 300ºC). He kūpono ia no ka hana ʻana i nā mea kūʻē pololei pololei a me ke kānana

    4. ʻO nā hiʻohiʻona ʻokoʻa o ka uea kūʻē Karma

    1) E hoʻomaka ana me ka uea wela uila Nickel Chromium Class 1, ua hoʻololi mākou i kekahi o ka Ni me
    Al a me nā mea ʻē aʻe, a pēlā i loaʻa ai kahi mea kūʻē pololei me ka hoʻomaikaʻi
    koena wela kū'ē a me ka ikaika electromotive wela i ke keleawe.
    Me ka hoʻohui ʻana o Al, ua lanakila mākou i ka hana ʻana i ka resistivity volume 1.2 mau manawa ʻoi aku ka nui
    ma mua o ka uea wela uila Nickel Chromium Class 1 a me ka ikaika tensile 1.3 manawa ʻoi aku ka nui.

    2) He liʻiliʻi loa ka helu lua wela β o Karmalloy wire KMW, - 0.03 × 10-6/ K2,

    a ʻo ka ʻaʻe wela kūʻokoʻa e hoʻohuli ʻia i kahi laina pololei i loko o kahi ākea
    pae wela.

    No laila, ua hoʻonohonoho ʻia ka coefficient wela i ka ʻawelike wela ma waena
    23 ~ 53 °C, akā, 1 × 10-6/K, ka awelika wela coefficient ma waena o 0 ~ 100 °C, hiki no hoi.
    e aponoia no ke koena wela.

    3) ʻO ka ikaika electromotive e kū'ē i ke keleawe ma waena o 1 ~ 100 °C he liʻiliʻi hoʻi, ma lalo o + 2 μV / K, a

    hōʻike i ke kūpaʻa maikaʻi loa i kahi manawa o nā makahiki he nui.

    4) Inā e hoʻohana ʻia kēia ma ke ʻano he mea kūʻē pololei, ʻo ka mālama wela wela haʻahaʻa
    koi ʻia e hoʻopau i nā distortions e like me ka hihia o Manganin wire CMW.
