Shenhai e fakamoʻoni fakaʻauha
Kuo pau ke ʻi ai ha ukamea ʻi he meʻangaue fakaʻuhila ʻoku fakavaʻe. ʻIkai ngata ai, ʻOku fie maʻu ʻa e equipotential fetuʻutaki ke taʻofi ʻa e ngaahi meʻa ʻe ala hoko mama koeʻuhi ko e ʻikai ke ʻaofi maluʻi mei taʻelavameʻa pea fakaʻehiʻehi mei he fakatuʻutamaki ʻo e ngaahi kalofiama ʻuhila mei he ʻau igniting kasa mixtures.
Ki he faʻahinga meʻangaue pehee, ʻOku totonu ke fakahoko ʻa e fakavaʻe mo e equipotential vaofi ʻi ha founga ʻe ua, ʻa ia ʻoku fakanaunau ai ʻa e meʻangaue takitaha ʻaki ʻa e fakavaʻe ʻi loto mo tuʻa feituʻu. Kuo pau ke tauhi ʻa e ngaahi feituʻu ko ʻeni ʻi he tuʻunga tatau pea fehokotaki mo e fakavaʻe polokalama ke fakapapauʻi ʻa e ola lelei ʻo e fakavaʻe mo e fetuʻutaki.
ʻOku totonu ke fokotuʻu ʻa e fakavaʻe ʻi loto ʻi he loki fakauaea (puha fale pe tefitoʻi loki ʻi ʻolunga), pea ʻoku totonu ke tuʻu ʻa e fakavaʻe ʻi tuʻa ʻi he tefitoʻi hiva ʻa e meʻangaue. ʻOku fakapapauʻi ʻe he meʻa ni ko e ngaahi konga ukamea lalahi ʻo e meʻangaue, hange ko e ʻEsia, ʻOku nau ʻi he tuʻunga tatau pe mo e kelekele.
Kuo pau ke feau ʻe he kau faihiva ʻoku fakaʻaongaʻi ki he fakavaʻe mo e equipotential ʻa e feituʻu ʻoku siʻisiʻi taha ai e kolosi, S. ʻI ha konga lahi ʻo e ngaahi tefitoʻi, Kapau ʻoku ʻikai laka hake ʻa e feituʻu ʻoku ʻi ai e sectional S0 ʻi he 16mm 5, pea ʻoku totonu ke ʻoua naʻa toe siʻi hifo ʻi he S0. Ki he S0 ʻi he vahaʻa ʻo e 16mm 5mo e 35mm 5, ʻOku totonu ke 16mm 5mm. Kapau ʻoku laka hake ʻa e S0 35mm 5, ʻOku totonu ke laka hake ʻi he vaeua ʻo e S0. Kapau ʻoku fuʻu siʻisiʻi ʻa e S0, ʻOku totonu ke ʻoua naʻa toe siʻi hifo ʻi he 4mm 8 ʻa e feituʻu ʻoku siʻisiʻi taha ai ʻa e kolosi.
Kuo pau ke fakapapauʻi ʻe he meʻangaue fetuʻutaki mo equipotential takitaha ʻa e ngaahi fehokotaki falalaʻanga ʻi he vahaʻa ʻo e kau faihiva mo e fakavaʻe feituʻu, mo e ngaahi meʻafua ke taʻofi ʻaki e loosening pe corrosion.
Ki he ngaahi meʻangaue fakaʻuhila ʻoku toʻotoʻo holo ʻe he grid, ʻe lava ke fakalaka atu ʻa e fakavaʻe ʻi tuʻa, ka ʻoku totonu ke fakahoko ʻa e fakavaʻe ʻi loto ʻo fakaʻaongaʻi ha keipolo ʻoku ʻi ai hano ʻelito. Kapau ʻoku ʻi ai ha puha ʻuhila ʻoku ʻi ai ha ngaahi vaʻakau ungrounded, ʻOku ʻikai fie maʻu ʻa e fakavaʻe. ʻIkai ngata ai, ʻOku ʻikai totonu ke fakavaʻe ʻa e ngaahi meʻangaue fakaʻuhila ʻoku liunga ua pe fakamalohia ʻaofi maluʻi mei.
