Nga ahuatanga hiko o nga taura photovoltaic

2024-11-19

1. DC ātete


Te ātete DC o te matua conductive o te otitaura photovoltaici te 20 ℃ kaore e nui ake i te 5.09Ω/km.


2. Te whakamatautau ngaohiko rumaki wai


Ko te taura kua oti (20m) ka rumakina ki te wai (20±5) ℃ mo te 1h, ka tukuna ki te whakamatautau ngaohiko 5min (AC 6.5kV, DC 15kV) kaore he pakaru.


3. Ngaohiko DC mo te wa roa


E 5m te roa o te tauira ka tukuna ki roto i te wai makuku kei roto te 3% konutai pūhaumāota (NaCl) i te (85±2) ℃ mo te (240±2)h, me te noho nga pito e rua ki te mata wai mo te 30cm. Ka tukuna he ngaohiko DC o te 0.9kV i waenga i te matua me te wai (ka hono te matua kawe ki te pou pai, ka hono te wai ki te pou kino). I muri i te tango i te tauira, ka mahia he whakamatautau ngaohiko rumaki wai, ko te ngaohiko whakamatautau he AC 1kV, kaore he pakaru.


4. Te parenga whakaahuru


Ko te parenga whakamarumaru o te taura photovoltaic kua oti i te 20°C kaua e iti iho i te 1014Ω·cm,


Ko te parenga whakamarumaru o te taura kua oti i te 90°C kia kaua e iti iho i te 1011Ω·cm.


5. He parenga mata o te kurupae


Ko te parenga mata o te taura taura kua oti kia kaua e iti iho i te 109Ω.
