SPD mo te Aratohu Rangatohu Rangatū Whakawhiwhi Hiko
Ko te whakaurunga o te SPD ki ia rohe whakamarumaru uira, kia rite ki te paerewa o te ahua hiko ngaohiko iti, hanga whakarōpūtanga o nga taputapu hiko i runga i te waahanga o runga ngaohiko, ko tana whakamaarama te tu ki te taumata ngaohiko hihiko ka taea te whakatau i te kowhiringa o te SPD.E ai ki te paerewa o te ahua hiko ngaohiko iti, hanga whakarōpūtanga o nga taputapu hiko i runga i te waahanga o runga ngaohiko hei taumata tohu, taumata uta, tohatoha me te taumata whakahaere, taumata tuku hiko.Ko tana whakamaarama ka mau i te taumata ngaohiko hiko: 1500V, 2500V, 4000V, 6000V.Ka rite ki ia ki te tūnga tāuta taputapu tiaki rerekē, me te rerekē te nāianei uira o rerekē rohe tiaki uira, ki te whakatau i te tūnga tāutanga o SPD mo te supply mana me te kaha pakaru-i runga.
Ko te tawhiti whakaurunga i waenga i ia taumata SPD kaua e neke ake i te 10m, ko te tawhiti i waenga i te SPD me nga taputapu whakamarumaru me poto rawa, kaua e neke ake i te 10m.Mena na te iti o te tuunga whakaurunga, kaore e taea te kii i te tawhiti o te whakaurunga, katahi me whakauru i te waahanga wehe i waenga i ia taumata SPD, kia tiakina te SPD o muri o te akomanga e te SPD o mua.I roto i te punaha hiko ngaohiko iti, ka taea e te hono i te inductor te whakatutuki i te kaupapa wehe.
SPD mo te maataapono whiriwhiringa whakangao punaha hiko
Max.ngaohiko whakahaere tonu: nui ake i nga taputapu tiaki, te max o te punaha.ngaohiko whakahaere tonu.
Pūnaha TT: Uc≥1.55Uo (Ko te Uo he punaha ngaohiko iti ki te ngaohiko raina kore)
Pūnaha TN: Uc≥1.15Uo
Pūnaha IT: Uc≥1.15Uo(Ko Uo he punaha ngaohiko iti ki te ngaohiko raina)
Taumata Tiaki Ngaohiko: iti iho i te maataki e mau ana i te ngaohiko o nga taputapu whakamarumaru
Whakatauhia te tukunga o naianei: kua whakatauhia kia rite ki te ahuatanga o te uira o te waahi kua whakauruhia me te rohe whakamarumaru uira.
