Huina 290/C17200 nickel-copper alloy wire for potentiometers/shunts

Hoʻohālikelike ʻia ka MANGANIN me ka haʻahaʻa haʻahaʻa haʻahaʻa ma waena o 20 a me 50 °C me ke ʻano parabolic o ka ʻaoʻao R(T), ke kūpaʻa lōʻihi lōʻihi o ke kūpaʻa uila, haʻahaʻa haʻahaʻa EMF wela me ke keleawe a me nā waiwai hana maikaʻi.
Eia nō naʻe, hiki ke loaʻa nā ukana wela kiʻekiʻe i loko o kahi ea non-oxidizing. Ke hoʻohana ʻia no nā resistors precision me nā koi kiʻekiʻe loa, pono e hoʻopaʻa pono ʻia nā mea pale a ʻaʻole pono ka mahana o ka noi ma mua o 60 ° C. ʻOi aku ka nui o ka mahana hana ma ka lewa e hopena i kahi neʻe kūʻē i hana ʻia e nā kaʻina oxidizing. ʻO ka hopena, hiki ke hoʻololi iki ka resistivity a me ka coefficient mahana o ka pale uila. Hoʻohana ʻia ia e like me ke kumu kūʻai haʻahaʻa haʻahaʻa no ka solder kālā no ke kau ʻana metala paʻakikī.

Nā kikoʻī
uea manganin/CuMn12Ni2 Uea hoʻohana ʻia i nā rheostats, nā mea pale, shunt etc.
Uea Manganin ( cupro-uwea manganese) he inoa hōʻailona no ka huila o 86% keleawe, 12% manganese, a me 2-5% nickel.
Hoʻohana ʻia ka uea Manganin a me ka foil i ka hana ʻana i ka resistor, ʻoi aku ka ammeter shunts, no ka mea, ʻoi aku ka nui o ka mahana o ka waiwai resintance a me ke kūpaʻa lōʻihi.

Ka hoohana ana o Manganin

Hoʻohana ʻia ʻo Manganin foil a me ka uea i ka hana ʻana i ka resistor, ʻoi aku ka nui o ka ammeter shunt, no ka mea, ʻaʻole kokoke loa i ka helu ʻana o ka waiwai kūʻē a me ke kūpaʻa lōʻihi.
Hoʻohana nui ʻia ka mea keleawe haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, thermal overload relay, a me nā huahana uila haʻahaʻa haʻahaʻa. ʻO ia kekahi o nā mea nui o nā huahana uila haʻahaʻa haʻahaʻa. ʻO nā mea i hanaʻia e kā mākou hui he mau hiʻohiʻona o ke kūpaʻa kūpaʻa maikaʻi a me ke kūpaʻa kiʻekiʻe. Hiki iā mākou ke hoʻolako i nā ʻano uea poepoe āpau, nā mea palahalaha a me nā lau.
