Waya Wopaka Wamkuwa Wokhala ndi Golide Wotentha Kwambiri wa Polyurethane Enameled Siliva
Waya wa maginito kapena waya wopangidwa ndi enamel ndi waya wamkuwa kapena aluminiyamu wokutidwa ndi wosanjikiza woonda kwambiri wa insulation. Umagwiritsidwa ntchito popanga ma transformer, ma inductor, ma motor, ma jenereta, ma speaker, ma hard disk head actuators, ma electromagnets, ma electric guitar pickups ndi ntchito zina zomwe zimafuna ma coil olimba a waya wotetezedwa.

Waya wokha nthawi zambiri umakhala ndi mkuwa wokonzedwa bwino, wopangidwa ndi electrolytically. Waya wa aluminiyamu nthawi zina umagwiritsidwa ntchito pa ma transformer akuluakulu ndi ma mota. Chotetezera nthawi zambiri chimapangidwa ndi zinthu zolimba za filimu ya polima m'malo mwa enamel, monga momwe dzinalo lingasonyezere.

Woyendetsa
Zipangizo zoyenera kwambiri zogwiritsira ntchito waya wa maginito ndi zitsulo zoyera zosagwiritsidwa ntchito, makamaka mkuwa. Zinthu monga mankhwala, zakuthupi, ndi zamakina zikaganiziridwa, mkuwa umaonedwa ngati chowongolera choyamba cha waya wa maginito.

Kawirikawiri, waya wa maginito umapangidwa ndi mkuwa woyengedwa bwino, wokonzedwa ndi electrolytically kuti ulole kuti ukhale wolimba kwambiri popanga ma coil a electromagnetic. Ma grade a mkuwa wopanda mpweya wabwino kwambiri amagwiritsidwa ntchito pochepetsa mpweya kapena m'ma mota kapena ma jenereta ozizira ndi mpweya wa hydrogen.

Waya wa aluminiyamu wopangidwa ndi maginito nthawi zina amagwiritsidwa ntchito ngati njira ina yopangira ma transformer ndi ma mota akuluakulu. Chifukwa cha mphamvu yake yochepa yamagetsi, waya wa aluminiyamu umafunika malo okulirapo nthawi 1.6 kuposa waya wamkuwa kuti ukhale ndi mphamvu yofanana ndi DC.

Kuteteza kutentha

Ngakhale kuti amatchedwa "enameled", waya wopangidwa ndi enamel siwokutidwa ndi utoto wa enamel kapena enamel wa vitreous wopangidwa ndi ufa wagalasi wosakanikirana. Waya wamakono wa maginito nthawi zambiri umagwiritsa ntchito gawo limodzi kapena anayi (ponena za waya wa quad-film) wa polymer film insulation, nthawi zambiri wamitundu iwiri yosiyana, kuti upereke gawo lolimba komanso losalekeza loteteza. Mafilimu oteteza maginito a maginito amagwiritsa ntchito (motsatira kuchuluka kwa kutentha) polyvinyl formal (Formvar), polyurethane, polyamide, polyamide, polyamide, polyamide-polyimide (kapena amide-imide), ndi polyimide. Waya woteteza maginito wa polyimide umatha kugwira ntchito mpaka 250 °C. Kuteteza maginito a maginito okhuthala kapena amakona anayi nthawi zambiri kumawonjezeredwa powakulunga ndi polyimide kapena tepi ya fiberglass yotentha kwambiri, ndipo ma windings omalizidwa nthawi zambiri amadzazidwa ndi vacuum ndi varnish yoteteza kuti awonjezere mphamvu yoteteza komanso kudalirika kwa nthawi yayitali kwa ma winding.

Ma coil odzichirikiza okha amakulungidwa ndi waya wokutidwa ndi zigawo ziwiri, lakunja kwambiri ndi thermoplastic yomwe imagwirizanitsa ma turns pamodzi ikatenthedwa.

Mitundu ina ya zinthu zotetezera kutentha monga ulusi wa fiberglass wokhala ndi varnish, pepala la aramid, pepala la kraft, mica, ndi filimu ya polyester imagwiritsidwanso ntchito kwambiri padziko lonse lapansi pazinthu zosiyanasiyana monga ma transformer ndi ma reactor. Mu gawo la mawu, waya wasiliva wopangidwa, ndi zinthu zina zotetezera kutentha, monga thonje (nthawi zina zimadzazidwa ndi chinthu china chothira/chokhuthala, monga sera wa njuchi) ndi polytetrafluoroethylene (Teflon) zimapezeka. Zipangizo zakale zotetezera kutentha zimaphatikizapo thonje, pepala, kapena silika, koma izi ndizothandiza pokhapokha ngati kutentha kuli kochepa (mpaka 105°C).

Kuti zikhale zosavuta kupanga, waya wina wa maginito wotentha pang'ono uli ndi chotetezera kutentha chomwe chingachotsedwe ndi kutentha kwa soldering. Izi zikutanthauza kuti kulumikizana kwa magetsi kumapeto kungapangidwe popanda kuchotsa chotetezera kutenthacho kaye.
