Shenhai e fakamoʻoni fakaʻauha
Fakatatau ki he ngaahi tefitoʻi moʻoni ʻo e lahi ange ʻa e malu ʻi he palani ʻo e fakamoʻoni fakaʻauha, ʻOku ʻi ai ha ngaahi fie maʻu pau ki he maluʻi ʻo e hiva, ʻaofi maluʻi mei ʻuhila, ngaahi fehokotakiʻanga uaea, fakaʻatā e meʻa fakaʻuhilá, creepage mamaʻo, mafana ʻo e ʻea, mo e windings ʻi he meʻangaue fakaʻuhila.
1. Maluʻi ʻo e hiva:
ʻI he angamahení, ʻOku peheni ʻa e tuʻunga malu ʻo e hiva ʻi he lahi ange ʻa e meʻangaue fakaʻuhila:
ʻOku fie maʻu ʻa e maluʻi siʻisiʻi taha IP54 ʻi he taimi ʻoku ʻasi ai ʻa e ngaahi konga ʻo e moʻui.
ʻOku fie maʻu ʻa e maluʻi IP44 siʻisiʻi taha ʻi he taimi ʻoku ʻi ai ha ngaahi konga insulated moʻui.
ʻI he taimi ʻoku ʻi loto ai ʻa e circuits pe systems malu ʻi he fakalahi e meʻangāue fakaʻuhila ki he malú, ʻOku totonu ke fakamavahevaheʻi ʻa e circuits ko ʻeni mei he ngaahi circuits ʻoku ʻikai malu. ʻOku totonu ke tuʻu ʻa e circuits taʻe ʻi ai ha tuʻunga malu ʻi ha hiva ʻoku ʻi ai ha tuʻunga malu ʻo ʻikai toe siʻi hifo ʻi he IP30, mo e ngaahi fakaʻilonga fakatokanga ʻo fakahaaʻi "ʻoua naʻa ke fakaava ʻi he taimi ʻoku ke moʻui ai!”
2. ʻAofi maluʻi mei ʻuhila:
ʻI he ngaahi tuʻunga ʻo e ngaue mo e ngaahi tuʻunga hulu ʻoku fakangofua, ʻa e ngaue lahi taha mafana ʻo e ʻea ʻo e lahi ange ʻa e meʻangaue fakaʻuhila ʻoku ʻikai totonu ke ne uesia lahi ʻa e ngaahi koloa fakamisini mo fakaʻuhila ʻo e naunau ʻaofi maluʻi mei. Ko ia, ʻOku totonu ke ʻoua naʻa toe siʻi hifo ʻi he 20K ʻa e ʻea vela mo e hauhau ʻo e naunau ʻaofi maluʻi mei ʻi he mafana ʻo e meʻangaue, mo e siʻisiʻi taha ʻi he 80 ° c.
3. Ngaahi fehokotakiʻanga uaea:
He tupulaki e malú meʻangāue fakaʻuhilá, ʻE lava ke vahevahe ʻa e ngaahi fehokotakiʻanga uaea ki he ngaahi fehokotakiʻanga fakaʻuhila mei tuʻa (feituʻu ʻoku fakahu ai ʻe he ngaahi uaea ʻi tuʻa ʻa e hiva) mo e ngaahi fehokotakiʻanga fakaʻuhila fakalotofonua (ngaahi fehokotakiʻanga ʻi he vahaʻa ʻo e ngaahi konga ʻi he hiva). ʻOku totonu ke fakatou fakaʻaongaʻi ʻe he ngaahi fehokotakiʻanga ʻi tuʻa mo loto ʻa e ngaahi uaea tefito pe uaea.
Ki he ngaahi fehokotakiʻanga ʻi tuʻa, ʻOku totonu ke fakahu ʻe he keipolo ʻi tuʻa ʻa e hiva ʻi ha meʻangaue keipolo.
Ki he ngaahi fehokotakiʻanga ʻi loto, ʻOku totonu ke fokotuʻutuʻu ʻa e uaea kotoa pe ke fakaʻehiʻehi mei he mafana ʻo e ʻea mo e ngaahi konga ʻoku hiki. ʻOku totonu ke fakaleleiʻi totonu ʻa e uaea loloa. ʻOku ʻikai totonu ke ʻi ai ha ngaahi hokotanga hui ʻi loto uaea.
ʻIkai ngata ai, kuo pau ke malu mo falalaʻanga ʻa e ngaahi fehokotakiʻanga ki he uaea-ki he-foʻi nati.
Ko hono fakanounoú, ʻOku totonu ke fakasiʻisiʻi ʻa e fakafepaki ʻi he uaea fetuʻutaki ke fakaʻehiʻehi mei he hoko ko ha “fakatuʻutāmaki e māfana ʻo” maʻuʻanga ignition; ʻe lava ʻe he ngaahi fetuʻutaki ʻoku homohomo ʻo fakatupu ha ngaahi kalofiama ʻuhila koeʻuhi ko e fetuʻutaki kovi.
4. Fakaʻata ʻa e ʻuhila mo Creepage mamaʻo:
Fakaʻatā e ʻuhilá (ʻa e mamaʻo taha ʻi he ʻea) mo creepage mamaʻo (ʻa e hala nounou taha ʻi he fukahi naunau maluʻi) ko ha ngaahi fakaʻilonga mahuʻinga ia ʻo hono fakaʻaongaʻi fakaʻuhila ʻo e lahi ange e meʻangāue fakaʻuhila ki he malú. Kapau ʻe fie maʻu, ʻe lava ke tanaki atu ʻa e ngaahi hui vakavaka pe grooves ki he ngaahi konga ʻo e maluʻi ke fakalahi ʻa e fakaʻata ʻuhila mo creepage mamaʻo: ngaahi hui vakavaka mo e maʻolunga ʻo e 2.5 MM mo e matolu ʻo e 1mm; grooves mo e loloto ʻo e 2.5 MM mo e maokupu ʻo e 2.5 MM.
5. Fakangatangata e Māfana ʻo e ʻEá:
ʻOku ʻuhinga ʻa e fakangatangata ʻo e ʻea ki he mafana maʻolunga taha ʻo e meʻangaue fakaʻuhila ki he fakaʻauha. Ko e mafana lahi taha ʻo e ngaahi konga ʻo e meʻangaue fakaʻuhila ʻe lava ke fetuʻutaki mo fakafepakiʻi Ko e mixtures kasa ko ha meʻa mahuʻinga ia ʻi hono fakapapauʻi ʻenau ngaue ki he fakamoʻoni fakaʻauha. ʻOku ʻikai totonu ke laka hake ʻa e mafana ʻo e ʻea fakamafana ʻi he fakangatangata ʻo e ʻea ki he meʻangaue fakaʻuhila ʻoku malu (kalasi mafana ʻo e meʻangaue ki he fakaʻauha), ʻi heʻene lava ʻo fakaulo ʻa e kasa ʻoku fekauʻaki mo ia.
ʻI he taimi ʻoku faʻufaʻu ai ke toe lahi ange ʻa e meʻangaue fakaʻuhila ki he malu, makehe mei hono fakakaukauʻi ʻo e ngaahi meʻa fakaʻuhila mo hono fakafuofuaʻi ʻo e ngaahi meʻa fakaʻuhila, ʻOku totonu ke fakakau ʻa e ngaahi meʻangaue maluʻi ʻo e ʻea ke taʻofi ʻaki ha ngaahi konga pau mei he fuʻu lahi ʻa e ʻea.
Windings:
Fakalahi e meʻangāue fakaʻuhila ki he malú hangē ko e mīsí, Transformers, solenoids, mo e ballasts ki he ngaahi maama maama tiupi ʻoku ʻi ai kotoa windings. ʻOku totonu ke maʻu ʻe he ai ha ngaahi fie maʻu ʻaofi maluʻi mei maʻolunga ange ʻi he ngaahi ai angamaheni (vakai ki he ngaahi tuʻunga moʻui fakafonua ʻoku fekauʻ) pea ʻoku totonu ke fakanaunau ʻaki ʻa e ngaahi meʻangaue maluʻi ʻo e ʻea ke taʻofi ʻa e ai mei he lahi ʻo e ʻea ʻi he tafa angamaheni pe ngaahi tuʻunga ʻo e fehalaaki. ʻE lava ke fokotuʻu ʻa e maluʻi ʻo e ʻea ʻi loto pe ʻi tuʻa ʻi he meʻangaue pea ʻoku totonu ke fekauʻaki mo ia faʻahinga ʻo e fakamoʻoni fakaʻauha.
