Shenhai e fakamoʻoni fakaʻauha
ʻI he taimi ʻoku aleaʻi ai e ngaahi tuʻunga ʻaofi maluʻi mei, ʻOku mahuʻinga ʻa e mafana ʻo e ʻea ʻi he moto ʻo e fakaʻauha. Ko hono moʻoni, ʻOku ʻi ai ha meʻa mahuʻinga ʻe ua ʻoku fie maʻu ke aʻu ki ai ʻa e felotoi:
Kalasi F ʻaofi maluʻi mei:
Lolotonga, ʻi he 90% ʻo e voltage maʻolunga mo maʻulalo ʻo e fakamoʻoni ʻi Siaina ko e kalasi F insulated. Ke fakaloloa ʻa e lifespan ʻo e moto ʻo e fakamoʻoni fakaʻauha, mahulu hake ʻi he 90% ʻOku fakahaaʻi ʻe he kau faʻu koloa “Kalasi F ʻaofi maluʻi mei, mafana ʻo e ʻea fakafuofuaʻi ʻe he kalasi B ngaahi fakangatangata” ʻi heʻenau ngaahi sipinga. ʻOku fakaʻata ʻe he kalasi B ʻaofi maluʻi mei ʻa e mafana ʻo e 130 ° c, lolotonga e fakangofua ʻa e kalasi F ki he 155 ° c. Fakakaukau ki ha mafana ʻo e ʻatakai ʻo e 40 ° c, founga hono ngaohi ʻo e koloa mo e naunau fluctuations ʻo e 5 ° c mo e 10 ° c, ʻa e fale ngaohiʻanga fakangatangata ʻa e mafana ʻo e ʻea ki he kalasi B insulated ʻoku fokotuʻu ʻa e moto ki he 80K, pea ki he Kalasi F, ʻOku 90K (95K ki he moto ʻo e fakamoʻoni ʻi lalofonua).
Kalasi H ʻaofi maluʻi mei:
ʻOku fakaʻata ʻe he kalasi H ʻaofi maluʻi mei ʻa e mafana ʻo e 180 ° c. Neongo ia, ʻa e palani, ngaohiʻanga koloa, ʻOku ʻi ai ha ngaahi, mo e lubricants ki he kalasi H ʻoku teʻeki ai ke fakaʻaongaʻi lahi ʻa e moto ʻi Siaina. Maʻa e kau faʻu koloa, ʻOku ʻikai faingataʻa hono ngaohi ʻo e kalasi H insulated windings; ʻOku maʻu ʻa e faingataʻa ʻi he mafana ʻo e ʻea. Ko ia, tuku kehe ʻo ka fie maʻu (hange ko e ngaahi ʻatakai mo e mafana ʻo e 60 ° c, pe feituʻu moto ʻo e fakamoʻoni fakaʻauha ʻOku fakangatangata pe ʻa e lahi), ʻOku totonu ke fakaʻehiʻehi mei hono fakaʻaongaʻi ʻo e kalasi H insulated e moto ʻo e fakaʻauha.
