Ntchito zikhalidwe zosiyanasiyana mica matepi

1. Mica tepi yamakina othamanga kwambiri ndi yoyenera pa matepi a vacuum pressure impregnation (VPI). Ili ndi mica yambiri, guluu wocheperako, ndi mica yapakati ya rabala. Itha kugwiritsidwa ntchito ngati chotchingira chachikulu chamagetsi othamanga kwambiri ndipo imakhala ndi magetsi abwino komanso makina; imatha kukwaniritsa zofunikira zamagalimoto Zofunikira pakukula kwamagetsi apamwamba komanso mphamvu yayikulu. Opanga magalimoto ambiri amagwiritsa ntchito tepi ya mica yaying’ono.

2. Mica tepi yopangira mphamvu yamphepo imachokera pa pepala la mica, nsalu yagalasi yopanda alkali yogwiritsira ntchito magetsi, filimu ya poliyesitala, filimu ya polyimide kapena filimu yosamva corona kumbali zonse ziwiri kapena mbali imodzi monga zopangira zowonjezera, zomatira za epoxy zosagwira kutentha kapena zina. resistant Thermal resin, yoyenera ma turbine amphepo akulu ndi apakatikati.

3. Pang’ono guluu mica ali ndi ndondomeko dongosolo osiyana kotheratu ndi matepi angapo, kutanthauza vacuum pressure impregnation (VPI) ndondomeko, amene ali patsogolo kutchinjiriza ndondomeko. Ili ndi mawonekedwe a mica yayikulu, mphamvu zamagetsi zabwino kwambiri, moyo wautali wotsekereza, kukhulupirika, kukana kutentha kwambiri komanso kukana kukalamba, makulidwe owonda otchingira, matenthedwe abwino amatenthedwe, kuchepetsa kukwera kwa kutentha kwagalimoto, njira yosavuta, komanso kuzungulira kwaufupi. .

4. Mica tepi ya madzi ndi magetsi ndi riboni-woboola pakati insulating zinthu zopangidwa ndi ufa mica pepala monga zinthu m’munsi, sanali magetsi alkali wopanda galasi nsalu mbali zonse monga kulimbikitsa zinthu, ndi womangidwa ndi epoxy zomatira. Imasinthasintha pansi pazikhalidwe zodziwika bwino ndipo imakhala ndi mphamvu zabwino zamagetsi ndi zamakina pambuyo pakuumba. Ndikoyenera kupanga kapena kutchinjiriza kwa hydraulic kwa ma coils a ma hydraulic jenereta ndi ma motor-voltage apamwamba omwe amagwira ntchito kutentha kwa 155 ℃.

5. Polyimide film powder mica tepi ndi insulating coil yopangidwa ndi mica pepala ndi polyimide filimu pambuyo kuphika, mapiringidzo ndi kudula, ndi kutentha zosagwira epoxy zomatira. Mica tepi imakhala yabwino kusinthasintha pansi pazochitika zabwinobwino. Pambuyo pochiza chilonda cha chilonda ndi varnish yoviika, imakhala ndi zinthu zabwino kwambiri za dielectric komanso mphamvu zamakina apamwamba. Ndikoyenera kutsekemera kwakukulu kwa ma traction motors ndi kutentha kwa 180-200 ndi kutsekemera kwa injini zina zosiyanasiyana ndi zipangizo zamagetsi.
