Fakapapauʻi ki he ngaahi naunau ukamea ki he meʻangaue fakaʻuhila ki he fakaʻauha

Ko ha tafaʻaki mahuʻinga ke fakakaukauʻi ki he ngaahi naunau ukamea ʻi he meʻangaue fakaʻuhila ko ʻenau uʻa fakaʻamu ke ne fakaulo ʻa e ʻea ʻo e kasa mixtures ʻi he ngaahi kalofiama fakamisini. Kuo fakahaaʻi ʻe he fakatotolo ʻoku ʻi ai ha fatongia lahi ʻo e faʻunga ʻo e ngaahi ukamea ko ʻeni ʻi he meʻa te nau malava ignition. Ke taʻofi e hoko ʻa e ignition fakamisini ʻi he ngaahi puha ukamea, ʻOku tuʻutuʻuni ʻa e ngaahi fakangatangata elemental pau. Ko e ngaahi tuʻunga moʻui ki he fakafepakiʻi ngaahi ʻātakaí – Ngaahi fie maʻu ki he meʻangaue fakalukufua – fakamahinoʻi ʻa e ngaahi meʻa ko ʻeni:

Kalasi ʻoku ou

ʻI hono ngaohi ʻo e RPL tuʻunga ʻo e FINEʻEIKI pe MB meʻangaue fakaʻuhila ki he fakaʻauha, ko e faʻunga ʻo e foila, magnesium, Titanium, pea kuo pau ke ʻoua naʻa laka hake ʻa e zirconium ʻi he ngaahi naunau ʻoku ʻoatu 15% ʻi he lahi, pea mo e peseti lahi ʻo e titanium, magnesium, pea kuo pau ke ʻoua naʻa lakasi ʻa e zirconium 7.5%.

Kalasi II

Ki he kalasi II-fakamoʻoniʻi ʻo e meʻangaue fakaʻuhila, ʻOku kehekehe pe ʻa e peseti fakakatoa ʻo e ngaahi ʻelemeniti mahuʻinga ʻi he ngaahi naunau ʻoku ʻoatu ʻo makatuʻunga ʻi he tuʻunga malu: Ki he meʻangaue EPLGa, ʻa e kakano fakakatoa ʻo e foila, magnesium, Titanium, pea kuo pau ke ʻoua naʻa lahi ange ʻa e zirconium 10%, mo magnesium, Titanium, pea zirconium ʻikai fuʻu lahi 7.5% fakakātoa; Ki he meʻangaue EPLGb, the aggregate content of magnesium and titanium must not exceed 7.5%; In the case of EPLGc equipment, apart from fans, fan covers, and ventilation hole baffles meeting EPLGb standards, there are no additional specific requirements.

Kalasi III

In manufacturing Class III explosion-proof electrical devices, the required total mass percentage of pertinent elements in the enclosure materials also varies with the protection level: For EPLDa devices, magnesium and titanium content should not exceed 7.5%; For EPLDb devices, the same limitation applies; For EPLDc devices, apart from fans, fan covers, and ventilation hole baffles adhering to EPLDb criteria, there are no further special requirements.
