Shenhai e fakamoʻoni fakaʻauha
ʻOku fie maʻu ʻe he conditioners ʻo e ʻea fakamoʻoni ʻa e fakaʻaongaʻi ʻo e ngaahi naunau ʻaofi maluʻi mei maʻolunga ange ke fakapapauʻi ʻoku fakatou malu mo falalaʻanga ʻenau tafa. ʻI he angamahení, ʻOku fakafaʻahinga ʻa e ngaahi naunau ʻaofi maluʻi mei ki ha foomu ʻe tolu: gaseous, huhuʻa, mo fefeka. ʻOku fakaʻaongaʻi ʻa Gaseous insulators ʻi he ngaahi tuʻunga maʻolunga voltage, huhuʻa insulators ko e lolo ko ʻi he voltage transformers, Neongo ʻoku predominantly fakaʻaongaʻi ʻa e insulators fefeka ʻi he ngaahi konga ʻaofi maluʻi mei ʻo e ngaahi meʻangaue fakaʻuhila.
Ngaahi fie maʻu ki he ngaahi naunau ʻaofi maluʻi mei:
1. Kuo pau ke maʻu ʻe he insulators fefeka ngaahi ʻulungaanga ʻoku ʻikai combustible mo e ulo-retardant.
2. ʻOku totonu ke insulators fefeka fakaʻaliʻali siʻisiʻi e hauhau absorption.
3. ʻOku insulators fefeka fie maʻu ke matuʻuaki e ngaahi meʻa fakaʻuhila.
4. Kuo pau ke insulators fefeka fakahaaʻi e fakafepaki lelei ʻaupito.
ʻOku ʻuhinga ʻa e fakafepaki vela ʻo e ʻaofi maluʻi mei fefeka ki he mafana ʻo e ʻea ʻa ia ʻe lava ke ngaue ai ʻa e ngaahi naunau ko ʻeni ʻi ha toloi loloa ʻo ʻikai holoa. ʻOku totonu ke tauhi ʻe he insulators fefeka ʻa e ngaahi koloa fakamisini ʻi he taimi ʻoku laka hake ai ʻa e mafana ʻi he 20.0 ° c pea ʻoua naʻa tuluta ki lalo ʻi he 80.0 ° c mei he mafana ʻo e meʻangaue. ʻOku fie maʻu ʻe he ngaahi meʻangaue fakaʻuhila kehekehe ha ngaahi tuʻunga kehekehe ʻo e fakafepaki vela.
ʻOku fakafaʻahinga ʻa e fakafepaki vela ʻo e insulators fefeka ki ha maaka ʻe valu: Y, A, E, B, F, H, C. ʻOku kau ʻi he ngaahi naunau ʻoku angamaheni ʻaki hono fakaʻaongaʻi ʻa e triazine asbestos Arc) pelesitiki mo dMC pelesitiki, mo e mafana ʻo e ʻea ʻi he vahaʻa ʻo e 130-155 ° c. ʻOku toe fakamahinoʻi foki ʻe he meʻangaue fakaʻuhila ki he malu ʻa e moto, transformer, pea electromagnet windings ke ʻufiʻufi ʻaki ha meʻa ʻe ua pe lahi ange ʻi he ngaahi meʻa ʻoku ʻikai ke ʻi ai ha uaea, ʻo ʻikai toe siʻi hifo he enamel ʻe taha ʻa e uaea, mo e faʻahinga QZ-2 ki he enamel matolu uaea.
ʻI he taimi tatau, ʻOku totonu ke ohi mai ʻe he mamalie ha taha ʻo e ngaahi founga impregnation: fakauku, pipiponu, pe vekiume ʻo e fāmá. ʻOku ʻikai totonu ke fakaʻaongaʻi ʻa e ngaahi founga fulunifo mo e lotu ki he impregnation. Kapau ʻoku fakaʻaongaʻi ʻa e solvents ʻoku ʻikai ke ʻi ai ha impregnants, ʻOku ne fie maʻu ha ongo impregnation mo e fakamomoa. ʻOku ʻikai ngofua ke ʻi ai ha ngaahi meʻangaue fakaʻuhila ʻoku siʻisiʻi ange ʻi he 0.25 MM. ʻI ha ngaahi meʻa makehe, ʻe lava ke fokotuʻutuʻu ʻa e ai ki he intrinsically malu pe ngaahi fale kuo fakamaʻu.
