Tlhaloso ea 1.Material General
1)
Manganineke motsoako oa 84% oa koporo, 12% ea manganese, le 4% nickel.
Manganin terata le foil li sebelisoa ha ho etsoa lihanyetsi, haholo-holo ammeter shunt, ka lebaka la mocheso oa eona o batlang o lekana le zero oa ho hanyetsa le botsitso ba nako e telele.Li-resistants tse 'maloa tsa Manganin li sebelitse e le tekanyetso ea molao bakeng sa ohm United States ho tloha ka 1901 ho ea ho 1990. Manganin terata e boetse e sebelisoa e le motlakase oa lisebelisoa tsa cryogenic, ho fokotsa mocheso oa mocheso pakeng tsa lintlha tse hlokang likhokahano tsa motlakase.
Manganin e boetse e sebelisoa litekanyong bakeng sa lithuto tsa maqhubu a khatello e phahameng (joalo ka a hlahisoang ke ho phatloha ha liqhomane) hobane e na le kutlo e tlase ea khatello empa e na le kutlo e phahameng ea hydrostatic pressure.
2)
Constantanke motsoako oa koporo-nickel hape o tsejoa e leEureka, Tsoela pele, leSekepe.Hangata e na le 55% koporo le 45% nickel.Tšobotsi ea eona e ka sehloohong ke resistivity ea eona, e leng kamehla ho feta mefuta e mengata ea mocheso.Li-alloys tse ling tse nang le li-coefficients tse tšoanang tsa mocheso o tlase lia tsebahala, joalo ka manganin (Cu86Mn12Ni2).
Bakeng sa tekanyo ea mefuta e meholo haholo, 5% (50 000 microstrian) kapa ka holimo, annealed constantan (P alloy) ke lisebelisoa tsa marang-rang tse khethiloeng ka tloaelo.Constantan ka sebopeho sena ke ductile haholo;'me, ka li-gauge tsa bolelele ba lisenthimithara tse 0.125 (3.2 mm) le ho feta, li ka hatelloa ho>20%.Leha ho le joalo, ho lokela ho hopoloa hore tlas'a mathata a phahameng a cyclic alloy ea P e tla bontša phetoho e sa feleng ea ho hanyetsa ka potoloho e 'ngoe le e' ngoe, 'me e etse hore ho be le phetoho e lumellanang le zero ho gauge ea khatello.Ka lebaka la tšobotsi ena, le tšekamelo ea ho hloleha ha marang-rang pele ho nako ka ho tsitsisa khafetsa, P alloy ha e khothalletsoe bakeng sa ts'ebetso ea cyclic strain.P alloy e fumaneha ka linomoro tsa STC tsa 08 le 40 bakeng sa tšebeliso ea litšepe le polasetiki, ka ho latellana.
2. Enamelled Wire Selelekela le ditshebediso
Le hoja e hlalosoa e le "enameled", terata e nang le enameled, ha e le hantle, ha e koahetsoe ka pente ea enamel kapa ea vitreous enamel e entsoeng ka phofo ea khalase e kopantsoeng.Mohala oa magnete oa sejoale-joale o sebelisa terata e le 'ngoe ho isa ho tse' nè (tabeng ea terata ea mofuta oa quad-film) ea polymer film insulation, hangata ea liqapi tse peli tse fapaneng, ho fana ka lera le thata, le tsoelang pele le sireletsang.Lifilimi tse sireletsang terata ea Magnet li sebelisa (ka tatellano ea ho eketseha ha mocheso) polyvinyl formal (Formar), polyurethane, polyimide, polyamide, polyster, polyester-polyimide, polyamide-polyimide (kapa amide-imide), le polyimide.Polyimide insulated magnet terata e khona ho sebetsa ho fihlela ho 250 °C.The insulation ea terata e teteaneng ea lisekoere kapa khutlonnetsepa ea makenete hangata e eketsoa ka ho e phuthela ka tepi e phahameng ea mocheso oa polyimide kapa fiberglass, 'me li-windings tse phethiloeng hangata li kenngoa ka vacuum ka varnish e sireletsang ho ntlafatsa matla a insulation le ho ts'epahala ha nako e telele.
Likhoele tse itšebetsang li entsoe ka terata e koahetsoeng bonyane ka likarolo tse peli, e ka ntle ke thermoplastic e kopanyang thinya ha e futhumatsoa.
Mefuta e meng ea ho kenya letsoho joalo ka khoele ea fiberglass e nang le varnish, pampiri ea aramid, pampiri ea kraft, mica le filimi ea polyester le tsona li sebelisoa haholo lefats'eng ka bophara bakeng sa lits'ebetso tse fapaneng joalo ka li-transformer le li-reactor.Lefapheng la molumo, terata ea kaho ea silevera, le li-insulators tse ling tse fapaneng, tse kang k'hothone (ka linako tse ling li tletse ka mofuta o itseng oa coagulating agent / thickener, joalo ka boka ba linotsi) le polytetrafluoroethylene (PTFE) e ka fumanoa.Lisebelisoa tsa khale tsa ho koala li ne li kenyelletsa k'hothone, pampiri, kapa silika, empa tsena li na le thuso bakeng sa lisebelisoa tsa mocheso o tlaase (ho fihlela ho 105 ° C).
Bakeng sa ho etsa bonolo, terata ea makenete ea boemo bo tlase ba mocheso e na le mohatsela o ka tlosoang ke mocheso oa solder.Sena se bolela hore likhokahano tsa motlakase lipheletsong li ka etsoa ntle le ho hlobola insulation pele.
