I-Round Copper Based NicrI-alloy 180degree Class Insulated Copper Wire

1.Incazelo Yezinto Ezivamile

1)

Manganiningxubevange yethusi engu-84%, i-manganese engu-12%, ne-nickel engu-4%.

I-Manganin wire kanye ne-foil kusetshenziswa ekukhiqizeni izinto eziphikisayo, ikakhulukazi i-ammeter shunt, ngenxa ye-coefficient yayo yokushisa ecishe ibe yiziro yokumelana nokuzinza kwesikhathi eside. Ama-Manganin resistor amaningana asebenza njengezinga elingokomthetho le-ohm e-United States kusukela ngo-1901 kuya ku-1990. Intambo ye-Manganin iphinde isetshenziswe njengekhondatha kagesi ezinhlelweni ze-cryogenic, ukunciphisa ukudluliswa kokushisa phakathi kwamaphoyinti adinga ukuxhunywa kukagesi.

I-Manganin iphinde isetshenziswe kumageji ocwaningweni lwamagagasi okwethuka komfutho ophezulu (njengalawo akhiqizwe ekuqhunyisweni kweziqhumane) ngoba inokuzwela okuphansi kobunzima kodwa izwela ingcindezi ye-hydrostatic ephezulu.

Constantaniyingxubevange yethusi-nickel eyaziwa nangokuthiEureka, Phambili, futhiIsikebhe. Ngokuvamile iqukethe u-55% wethusi no-45% we-nickel. Isici saso esiyinhloko yi-resistivity yayo, ehlala njalo phezu kwezinhlobonhlobo zamazinga okushisa. Amanye ama-alloy anama-coefficients okushisa aphansi afanayo ayaziwa, njenge-mangan (Cu₈₆Mn₁₂Ni₂).

Esilinganisweni sezinhlobo ezinkulu kakhulu, u-5% (50 000 microstrian) noma ngaphezulu, i-annealed constantan (P alloy) iwumsebenzi wegridi ovame ukukhethwa. I-Constantan kuleli fomu i-ductile kakhulu; futhi, ku-gauge yobude obungu-0.125 amayintshi (3.2 mm) nangaphezulu, ingacindezelwa ibe ngu->20%. Kufanele kukhunjulwe, nokho, ukuthi ngaphansi kwezinhlobo eziphakeme zama-cyclic ingxubevange ye-P izobonisa ushintsho oluthile lokumelana okuhlala njalo ngomjikelezo ngamunye, futhi ibangele ukuguquguquka okunguziro okuhambisanayo kugeji yobunzima. Ngenxa yalesi sici, kanye nokuthambekela kokwehluleka kwegridi ngaphambi kwesikhathi ngokuqina okuphindaphindiwe, i-P alloy ayinconywa ngokujwayelekile ezinhlelweni zohlobo lwe-cyclic. I-P ingxubevange iyatholakala nezinombolo ze-STC zika-08 no-40 ukuze zisetshenziswe ezinsimbi namapulasitiki, ngokulandelana.

2. Isingeniso Socingo Olunamelisiwe kanye nezinhlelo zokusebenza

Nakuba kuchazwa ngokuthi “oqweqwe lwawo”, ucingo olunameleli, empeleni aluvalwanga ngopende lwe-koqweqwe lwawo noma ngoqweqwe lwe-vitreous olwenziwe ngempushana yengilazi ehlanganisiwe. Intambo kazibuthe yesimanje ngokuvamile isebenzisa isendlalelo esisodwa kuya kwezine (esimeni sezintambo zohlobo lwefilimu eyi-quad) ye-polymer insulation yefilimu, evamise ukuba yiziqalo ezimbili ezihlukene, ukuze zinikeze ungqimba oluqinile, oluqhubekayo lokuvikela. Amafilimu okuvikela izintambo zikazibuthe asetshenziswa (ngokulandelana kwebanga lokushisa elikhulayo) i-polyvinyl ehlelekile (Formar), i-polyurethane, i-polyimide, i-polyamide, i-polyster, i-polyester-polyimide, i-polyamide-polyimide (noma i-amide-imide), ne-polyimide. I-Polyimide insulated magnetic wire iyakwazi ukusebenza kufika ku-250 °C. Ukufakwa kwe-insulation yesikwele esiwugqinsi noma ucingo lukazibuthe elingunxande kuvame ukwengezwa ngokusonga nge-polyimide ephezulu noma nge-fiberglass tape, futhi ama-windings aqediwe ngokuvamile afakwe i-vacuum evikelayo ukuze kuthuthukiswe amandla okufaka umoya nokuthembeka kwesikhathi eside kokusonteka.

Amakhoyili azisekelayo alinyazwa ngocingo olunamekwe okungenani ngezingqimba ezimbili, engaphandle kuyi-thermoplastic ehlanganisa ukuphenduka ndawonye lapho kushisa.

Ezinye izinhlobo zokugquma ezifana nentambo ye-fiberglass enevarnish, iphepha le-aramid, i-kraft paper, i-mica, nefilimu ye-polyester nazo zisetshenziswa kabanzi emhlabeni wonke ekusetshenzisweni okuhlukahlukene njengama-transformer nama-reactors. Emkhakheni womsindo, intambo yokwakhiwa kwesiliva, nezinye izivikeli ezihlukene, ezifana nekotini (ngezinye izikhathi ezigcwele uhlobo oluthile lwe-ejenti ebophayo/ugqinsi, njenge-bex) ne-polytetrafluoroethylene (PTFE) ingatholwa. Izinto zokufaka ezindala zahlanganisa ukotini, iphepha, noma usilika, kodwa lezi ziwusizo kuphela ekufakweni kwezinga lokushisa eliphansi (kufika ku-105°C).

Ukuze kube lula ukukhiqiza, olunye ucingo lukazibuthe lwezinga lokushisa eliphansi lunokwahlukanisa okungasuswa ukushisa kwe-solder. Lokhu kusho ukuthi ukuxhunywa kukagesi ekugcineni kungenziwa ngaphandle kokukhumula okokufaka kuqala.
