Round Copper Based NicrAlloy 180digiri Class Insulated Enameled Copper Waya

1.Material General Description

1)

ManganinAlloy na yawanci 84% jan karfe, 12% manganese, da 4% nickel.

Manganin waya da foil ana amfani da su wajen kera resistors, musamman ammeter shunt, saboda kusan sifili madaidaicin juriya da kwanciyar hankali na dogon lokaci. Yawancin Manganin resistors sunyi aiki a matsayin ma'auni na doka don ohm a Amurka daga 1901 zuwa 1990. Hakanan ana amfani da waya ta Manganin azaman jagorar lantarki a cikin tsarin cryogenic, yana rage saurin zafi tsakanin maki waɗanda ke buƙatar haɗin lantarki.

Hakanan ana amfani da manganin a cikin ma'auni don nazarin raƙuman girgiza mai ƙarfi (kamar waɗanda aka samo su daga fashewar abubuwan fashewa) saboda yana da ƙarancin damuwa amma yana da ƙarfin haɓakar matsin lamba.

2)

Constantanshi ne na jan karfe-nickel gami kuma aka sani daEureka, Gaba, kumaJirgin ruwa. Yawanci ya ƙunshi 55% jan karfe da 45% nickel. Babban fasalinsa shine tsayayyarsa, wanda ke dawwama akan yanayin zafi da yawa. An san sauran alluna masu ƙarancin zafin jiki iri ɗaya, kamar manganin (Cu₈₆Mn₁₂Ni₂).

Don auna manyan ƙwayoyi, 5% (50 000 microstrian) ko sama, Ananed Constantan (P Alloy) shine kayan Gridy. Constantan a cikin wannan nau'i ne sosai ductile; kuma, a cikin tsayin ma'auni na inci 0.125 (3.2 mm) kuma ya fi tsayi, ana iya takurawa zuwa>20%. Ya kamata a ɗauka a zuciya, duk da haka, cewa a ƙarƙashin manyan nau'ikan cyclic P alloy zai nuna wasu canje-canje na juriya na dindindin tare da kowane zagayowar, kuma ya haifar da canjin sifili daidai a cikin ma'auni. Saboda wannan siffa, da kuma halin gazawar grid da wuri-wuri tare da maimaita iri, P alloy ba a saba da shawarar don aikace-aikacen nau'in cyclic ba. Ana samun P alloy tare da lambobin STC na 08 da 40 don amfani akan karafa da robobi, bi da bi.

2. Enamelled Waya Gabatarwa da aikace-aikace

Ko da yake an kwatanta shi da “enameled”, wayar enameled ba, a haƙiƙa, ba a lulluɓe ta da ko dai wani fenti na enamel ko kuma da enamel mai ɗanɗano da aka yi da foda ta gilashi. Wayar maganadisu ta zamani yawanci tana amfani da yadudduka ɗaya zuwa huɗu (a yanayin nau'in nau'in nau'in fim ɗin quad-fim) na rufin fim ɗin polymer, sau da yawa na nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan biyu, don samar da Layer mai tsauri, mai ci gaba da rufewa. Ana amfani da fina-finai masu rufe waya ta Magnet (domin yawan zafin jiki) polyvinyl form (Formar), polyurethane, polyimide, polyamide, polyster, polyester-polyimide, polyamide-polyimide (ko amide-imide), da polyimide. Polyimide insulated magnet waya yana iya aiki har zuwa 250 ° C. Ana ƙara ƙarar murfin murabba'i mai kauri ko waya magnet mai rectangular sau da yawa ta hanyar lulluɓe shi da babban zafin jiki na polyimide ko tef ɗin fiberglass, kuma an cika iska mai zafi sau da yawa tare da injin insulating don inganta ƙarfin rufin da kuma tsawon lokaci na amincin iska.

Ana raunata coils masu ɗaukar kai da waya da aka lulluɓe da aƙalla yadudduka biyu, na ƙarshe shine thermoplastic wanda ke haɗa jujjuyawar lokacin zafi.

Sauran nau'ikan rufi kamar fiberglass yarn tare da varnish, takarda aramid, takarda kraft, mica, da fim ɗin polyester kuma ana amfani da su sosai a duk faɗin duniya don aikace-aikace daban-daban kamar masu canza wuta da reactors. A cikin sashin sauti, ana iya samun waya na ginin azurfa, da sauran insulators iri-iri, irin su auduga (wani lokaci ana cika su da wani nau'in wakili na coagulating/thickener, kamar beeswax) da polytetrafluoroethylene (PTFE). Tsofaffin kayan rufewa sun haɗa da auduga, takarda, ko siliki, amma waɗannan suna da amfani kawai don aikace-aikacen ƙananan zafin jiki (har zuwa 105 ° C).

Don sauƙi na masana'antu, wasu ƙananan zafin jiki na waya magnet suna da rufin da za'a iya cirewa ta hanyar zafi na soldering. Wannan yana nufin cewa ana iya yin haɗin wutar lantarki a ƙarshen ba tare da cire murfin da farko ba.
