Aratohu Kōwhiri Raupapa Pūnaha Tuku Hiko SPD mō te Pūnaha Tuku Hiko

Ko te whakaurunga o te SPD ki ia rohe tiaki uira, e ai ki te paerewa o te āhua hiko ngaohiko iti, ka whakarōpūtia ngā taputapu hiko kia rite ki te kāwai ngaohiko nui, ka taea e tōna taumata ngaohiko ātete ārai te whakatau i te kōwhiringa o te SPD. E ai ki te paerewa o te āhua hiko ngaohiko iti, ka whakarōpūtia ngā taputapu hiko kia rite ki te kāwai ngaohiko nui hei taumata tohu, taumata uta, taumata tohatoha me te taumata whakahaere, taumata tuku hiko. Ko ōna taumata ngaohiko ātete ārai ko: 1500V, 2500V, 4000V, 6000V. E ai ki te tūranga tāutanga taputapu tiakina me te ia uira rerekē o ngā rohe tiaki uira rerekē, ka taea te whakatau i te tūranga tāutanga o te SPD mō te tuku hiko me te kaha pakaru.

Kaua te tawhiti tāutanga i waenga i ia SPD taumata e neke atu i te 10m, me poto te tawhiti i waenga i te SPD me ngā taputapu tiakina, kaua e neke atu i te 10m. Mēnā nā te herenga o te tūranga tāutanga, kāore e taea te kī taurangi i te tawhiti tāutanga, me tāuta te wāhanga wetewete i waenga i ia SPD taumata, me tiaki te SPD akomanga o muri e te SPD akomanga o mua. I roto i te pūnaha tuku hiko ngaohiko iti, mā te hono i tētahi inductor ka taea te whakatutuki i te kaupapa wetewete.

Te kaupapa whiriwhiri whakatakotoranga pūnaha tuku hiko mō te SPD

Ngaohiko whakahaere tonu mōrahi: he nui ake i ngā taputapu tiakina, ko te ngaohiko whakahaere tonu mōrahi o te pūnaha.

Pūnaha TT: Uc≥1.55Uo (Ko Uo te pūnaha ngaohiko iti ki te ngaohiko raina kore)

Pūnaha TN: Uc≥1.15Uo

Pūnaha IT: Uc≥1.15Uo (Ko Uo te pūnaha ngaohiko iti ki te ngaohiko raina)

Taumata Tiaki Ngaohiko: iti iho i te parenga ārai e tu atu ana i te ngaohiko hiko o ngā taputapu tiakina

Ia tukunga kua whakatauria: ka whakatauhia kia rite ki te āhuatanga uira o te tūranga kua tāuta me te rohe tiaki uira.
