HG2B Poutū Fuse Rail Whakawhiti Momotu
Ka whakamahia te Huka-whakawhiti HG2B i raro i te 690V o te Ngaohiko Whakatau.He naianei tuatahi 160A ki te 630A.I roto i te punaha hiko, ko te nuinga o te waa ka whakamahia hei pana hiko, pana wehe, me te pana ohorere.
He momo hononga hono: NH00 mo te 160A, NH1 mo te 250A, NH2 mo te 400A me te NH3 mo te 630A
Ngā au kua whakatauhia: 4, 6, 10, 16, 20, 25, 32, 35, 40, 50, 63, 80, 100, 125, 160, 200, 224, 250, 300, 315, 305, 40, 4 me te 630 ngongo,
Ko te ngaohiko whakamaarama o te momo whakahiato momo HG2B he AC800V.Ko te 400V, 690V, me te 50HZ te ngaohiko whakahaere me nga tohu auau.Kaore e whakamahia ana tenei huringa ki te hiko i te motuka kotahi;engari, ka noho hei pana hiko, pana wehe, me te pana ohorere me te mahi o te tiaki iahiko me nga iahiko poto poto me nga motuka motuka.
Ina whakakapihia e te maripi kaaiti he whae, karekau he mana o tenei pana ki te utaina i te ara iahiko hiko me nga ara iahiko poto, engari ka tutuki noa i te whakatauranga i hoahoatia kia tu me te kaha ki te wehe i nga whakamahinga ina ka pakaru te meneti.
Ka tutuki tenei hua ki nga paerewa GB14048.3-2002.IEC 947-3 (1999)
Taiao e tika ana
1. Ko te pāmahana ambient kaua e neke ake i te +40 ℃;ko te toharite i roto i te 24 haora kaua e neke ake i te +35℃;ko te tepe o raro o te pāmahana ambient ko -5℃.
2. Me whakanoho te pana ki te teitei e kore e teitei ake i te 2,000m.
3. Ko te RH ambient o te waahi whakauru kaua e neke atu i te 50% i raro i te teitei o te pāmahana + 40 ℃ me te uara RH teitei ka whakaaetia i raro i te iti o te pāmahana;kia kaua e neke ake te pāmahana iti rawa o te marama mākū + 25 ℃ me te RH mōrahi toharite o te marama kaua e neke ake i te 90 ℃.
4. Me whakauru te pana ki tetahi waahi me te parahanga taiao o te akomanga 3.
5. Ko te akomanga whakaurunga o te whakawhiti me III.
6. Me whakauru te pana ki roto i te waahi kaore he paanga me te wiri.
