I-Round Copper esekelwe kwi-NicrIngxubevange 180isidanga Class Insulated I-Enameled Copper Wire

1.INkcazelo Jikelele yezinto eziphathekayo

1)

Manganinyingxubevange yobhedu eyi-84%, i-12% yemanganese, kunye ne-4% yenikeli.

I-Manganin wire kunye nefoyile zisetyenziswa ekwenzeni izinto ezixhathisayo, i- particularl ammeter shunt, ngenxa ye-zero coefficient yobushushu bokumelana kunye nokuzinza kwexesha elide. Iqela le-Manganin resistors lisebenza njengomgangatho osemthethweni we-ohm e-United States ukusuka kwi-1901 ukuya ku-1990. I-Manganin wire iphinda isetyenziswe njenge-conductor yombane kwiinkqubo ze-cryogenic, ukunciphisa ukuhanjiswa kobushushu phakathi kwamanqaku afuna ukudityaniswa kombane.

IManganin ikwasetyenziswa kwiigeyiji kuphononongo lwamaza oxinzelelo oluphezulu (afana nalawo aveliswe kukuqhushumba kweziqhushumbisi) kuba inovakalelo oluphantsi loxinzelelo kodwa inovakalelo oluphezulu lwe-hydrostatic yoxinzelelo.

2)

Constantanyingxubevange yobhedu-nickel eyaziwa ngokubaEureka, Phambili, kwayeIsikhitshane. Ngokuqhelekileyo iqulethe i-55% yobhedu kunye ne-nickel ye-45%. Into ephambili yayo yi-resistivity yayo, ehlala ihleli phezu kwamaqondo obushushu amaninzi. Ezinye ii-alloys ezine-coefficients zobushushu obuphantsi ngokufanayo ziyaziwa, njenge-mangan (Cu₈₆Mn₁₂Ni₂).

Ngomlinganiselo weentlobo ezinkulu kakhulu, i-5% (50 000 microstrian) okanye ngaphezulu, i-annealed constantan (P alloy) yimathiriyeli yegridi ekhethwa ngokuqhelekileyo. I-Constantan kule fomu i-ductile kakhulu; kwaye, kwi-gauge ubude be-0.125 intshi (3.2 mm) kwaye ubude, bunokuxinzelelwa kwi->20%. Kufuneka kukhunjulwe, nangona kunjalo, ukuba phantsi koxinzelelo oluphezulu lwe-cyclic i-alloy ye-P iya kubonisa utshintsho olusisigxina lokumelana nomjikelo ngamnye, kwaye ibangele ukutshintshwa kwe-zero ehambelanayo kwi-gauge yoxinzelelo. Ngenxa yolu phawu, kunye notyekelo lokusilela kwegridi kwangaphambi kwexesha ngoxinzelelo oluphindaphindiweyo, i-P alloy ayiqhelekanga ukucetyiswa kwi-cyclic strain application. I-P alloy ifumaneka ngeenombolo ze-STC ze-08 kunye ne-40 ukuze zisetyenziswe kwiintsimbi kunye neeplastiki, ngokulandelelanayo.

2. Intshayelelo yocingo enamelled kunye nezicelo

Nangona ichazwa njenge "enameled", ucingo olunameleliyo, enyanisweni, aluqatywanga kunye nomaleko wepeyinti ye-enamel okanye nge-vitreous enamel eyenziwe ngomgubo weglasi edityanisiweyo. Ucingo lwemagnethi lwangoku lusebenzisa umaleko omnye ukuya kwezine (kwimeko yocingo lodidi lwefilimu ezine) lwepolymer yokugqunywa kwefilim, ehlala iziqalo ezimbini ezahlukeneyo, ukunika umaleko oqinileyo, oqhubekayo wokugquma. Iifilimu zokukhusela i-magnetic wire insulating zisebenzisa (ngolandelelwano lokunyusa izinga lobushushu) i-polyvinyl esemthethweni (i-Formar), i-polyurethane, i-polyimide, i-polyamide, i-polyster, i-polyester-polyimide, i-polyamide-polyimide (okanye i-amide-imide), kunye ne-polyimide. Ucingo lwemagnethi olugqunyiweyo lwePolyimide luyakwazi ukusebenza ukuya kuthi ga kwi-250 °C. I-insulation yesikweri esityebileyo okanye i-rectangular magnetic wire ihlala ikhuliswa ngokuyisongela nge-polyimide ephezulu yobushushu okanye i-fiberglass tape, kwaye i-windings egqityiweyo ihlala i-vacuum ifakwe nge-varnish yokugquma ukuphucula amandla okugquma kunye nokuthembeka kwexesha elide lokujija.

Iikhoyili ezizixhasayo zenzakala ngocingo olufakwe ubuncinci bemigangatho emibini, eyona ingaphandle yi-thermoplastic edibanisa ukujika kunye xa ishushu.

Ezinye iintlobo zokugquma ezinje ngelaphu yefiberglass enevanishi, iphepha learamid, ikraft paper, i-mica, kunye nefilimu yepolyester nazo zisetyenziswa ngokubanzi kwihlabathi liphela kwizicelo ezahlukeneyo ezifana neziguquli kunye neereactor. Kwicandelo le-audio, ucingo lolwakhiwo lwesilivere, kunye nezinye i-insulators ezahlukahlukeneyo, ezifana nekotoni (ngamanye amaxesha zifakwe kwi-agent ye-coagulating / thickener, njenge-bewax) kunye ne-polytetrafluoroethylene (PTFE) inokufumaneka. Izinto zokugquma ezindala zibandakanya umqhaphu, iphepha, okanye isilika, kodwa ezi ziluncedo kuphela kwizicelo zobushushu obuphantsi (ukuya kuthi ga kwi-105 ° C).

Ukwenza kube lula ukwenza, enye i-low-grade-grade magnetic wire ine-insulation enokususwa kubushushu be-soldering. Oku kuthetha ukuba uqhagamshelo lombane eziphelweni lunokwenziwa ngaphandle kokukhulula i-insulation kuqala.
