ʻIkai ha kalava optic e mafana ʻo e ʻea ,founga vakaiʻi ʻo e māfana ʻo e ʻeá.
ʻI he ngaahi taʻu kimui ní, Kuo iku hono fakaʻaongaʻi ʻo e ngaahi meʻangaue fakaʻapi ki ha tupulaki lahi ʻi he feituʻu ʻo e kolo mo e ʻuhila ʻi he feituʻu ʻuta, ʻa ia kuo ne fokotuʻu foki ha ngaahi fie maʻu maʻolunga ki he malu mo e ala falalaʻanga ʻo e malohi ʻi he grid ʻo e malohi. ʻI he grid ʻo e malohi, ʻOku ʻi ai ha fatongia ʻe ua ʻo e voltage switchgear ʻi hono tapuni mo hono motuhi ʻo e ngaahi laine ʻuhila, pea pehe ki hono maluʻi ʻo e System. Koeʻuhi ko e tupu vave ʻa e lahi ʻo e ngaahi polokalama voltage switchgear ʻi he netiueka tufakiʻanga naunau, ʻOku fakahaaʻi ʻe he fakamatala ʻi he fakaʻosinga ʻo e ngaahi taʻu ʻo e 1990, Naʻe lahi hake ʻi he 270000 ʻOku ngaue ʻa e tufakiʻanga naunau ʻi he polokalama malohi fakafonua, ʻa ia naʻe liunga ua hono fakafehoanaki ki he taʻu kimuʻa. Neongo ia, ʻOku uesia ʻa e voltage maʻolunga switchgear ʻi he netiueka 10kV ʻi he ngaahi meʻa kehekehe hange ko e ngaue fakaʻaho, maumau mei tuʻa, mo e ngaahi laine ʻoku fonu, tupu ai ha ngaahi fehalaaki fakamafana lahi. Tautautefito ki he lolotonga ʻo e faʻahitaʻu mafana mo e ngaahi vahaʻataimi uta maʻolunga ʻo e malohi ʻi he taʻu kotoa pe, ʻOku faʻa hoko ʻa e maumau fakalukufua naʻe fakatupu ʻe he fakamafana ʻo e ngaahi fetuʻutaki ʻi loto ʻi he switchgear. Lolotonga e tafa taimi loloa, ʻe lava ke vela ʻa e ngaahi fetuʻutaki mo e busbar ʻo e meʻa kamosi koeʻuhi ko e toulekeleka pe lahi ange ʻa e fakafepaki ki he fetuʻutaki. ʻE lava ke fakatupu ʻe he fuʻu fakamafana ʻa e holoa ʻo e naunau ʻaofi maluʻi mei, fakaiku ki he malfunctions pea aʻu ʻo lolotonga ʻi he switchgear. Ko hono aofangatuku, ʻoku iku ia ki he hoko ʻa e afi pe malohi lahi outages.
Founga fua ʻo e ʻea ki he switchgear
A. Sivi ʻo e tohi lēsoní
Ko hono fakaava ʻo e kapineti ki he sivi ko e taimi lahi mo e ngaue lahi, mo e lavameʻa ʻi he ngaue maʻulalo. ʻIkai ngata ai, ʻOku ʻikai fakafiemalie ke siviʻi e voltage maʻolunga, tautautefito ki he ultra-maʻolunga voltage switchgear, pea ʻoku ne toe ʻomi foki mo ha ngaahi fakatuʻutamaki pau.
B. Infrared e fua ʻo e ʻea
Ko e faingamalie ko ia ke fakaʻaongaʻi ha infrared mofi toʻotoʻo ke vakaiʻi ʻaki e switchgear ʻi ha feituʻu mamaʻo pau ʻoku faingamalie, ka ko e meʻa ʻoku hoko ko e taimi lahi mo e ngaue lahi, pea ʻoku fie maʻu ki ai ha taimi mo ha ngaahi poini pau, pea mo e fua ʻo e ʻeá ʻoku ʻikai tonu.
Ko e maama tiupi filo optic mofi ki he switchgear lava ʻo fakaʻehiʻehi lelei mei he drawbacks ʻo e ngaahi founga fua ʻo e ʻea ʻi ʻolunga, mo e fua totonu ʻo e ʻea pea ʻikai fie maʻu ke vakaiʻi e tohi lesoni, pea lava ke fakafuofuaʻi e mafana ʻo e ʻea 24 houa ʻe taha he ʻaho.
ʻOku fakaʻaongaʻi ʻa e switchgear mofi ke ʻiloʻi ʻa e mafana ʻo e ngaahi meʻangaue kehekehe ʻi loto ʻi he switchgear, pea ʻoku lahi e ngaahi meʻafua kehekehe motolo kautaha fotunga mo e distributors ʻi he maketi.
ʻI he lahi ange ʻa e tokanga ʻa e kau faʻu koloa ki he fua ʻo e ʻea ʻoku fie maʻu ke switchgear, ʻOku fakanatula pe ke ʻi ai ha ngaahi meʻangaue lahi ange ki hono fakaʻilo switchgear, pea ko e switchgear ʻo e ʻea ko e taha ia ʻo kinautolu. Neongo ia, ʻOku lahi ha ngaahi switchgear ʻo e ʻea ʻi he maketi, ko e founga hono fili ʻo e ngaahi meʻafua switchgear totonu ʻo e ʻea.
1. Fili ʻa e ngaahi meʻafua ʻoku feʻunga mo e ʻea
Ki he maama tiupi feʻunga taha optic e fua ʻo e ʻea ki he switchgear, tufaki e filo optic ʻOku feʻunga ʻa e fua ʻo e ʻea ki he fakatafe keipolo pe tunnels, mo hono puleʻi ʻo e ʻea ki he ngaahi fakatokanga ʻoku feʻunga mo hono fakaʻaongaʻi ʻo e filo optic grating afi detectors, mo e alā meʻa pe.
2. Tonu e fua ʻo e ʻea
Kuo pau ke lava ʻe ha meʻafua ʻo e ʻea ki ha switchgear ʻo fakafuofuaʻi totonu ʻa e mafana ʻo e ʻea, ka ʻikai, ʻoku ʻi ai ha fakatuʻutamaki ki he ngaahi ngaue malohi. Kapau ʻoku ʻikai tonu ʻa e fua ʻo e ʻea, te ne uesia ʻa e ngaue angamaheni ʻa e switchgear.
3. Tuʻu maʻu ʻi he fua ʻo e ʻea
Kuo pau ke lava ʻo ngaue stably ʻa e mafana ʻo e ʻea ʻi ha taimi loloa pea he ʻikai lava palopalema hili ha vahaʻataimi, ʻa ia ʻoku ne fakahaaʻi ko e tuʻunga lelei ʻo e koloa ʻoku ʻikai ko e tuʻunga moʻui.
4. Hili e ngaue tokoni ki he fua ʻo e ʻea
Hili hono fakatau atu ha meʻangaue ki hono fua ʻo e ʻea, kuo pau ke fatongia kakato ʻaki ʻe ha tokotaha ngaohi kapeti ʻa e koloa, fakapapauʻi ʻoku ʻosi fokotuʻu ʻa e ngaahi fakahinohino ki hono fakaʻaongaʻi mo hono tokangaʻi ʻo e koloa.
ʻOku ʻomi ʻe he FJINNO maama tiupi filo optic e fua ʻo e ʻea koloa mo e switchgear filo optic e mafana ʻo e ʻea ʻi ha totongi feʻunga. ʻOku talitali lelei koe ke fetuʻutaki mai kiate kimautolu!
