Whakaahuatanga Poto:
Ko te pūwhakawhiti ara iahiko hau atamai W2-1 600 Series (e kiia nei i muri nei ko te ara iahiko
he pai te breaker) mō ngā whatunga tohatoha me te auau o te AC 50Hz, te mahi kua whakatauria
te ngaohiko tae atu ki te 690V me te iahiko whakatauranga mai i te 200A ki te 1600A. E whakamahia ana hei tohatoha
te pūngao hiko me te tiaki i ngā raina me ngā taputapu hiko mai i te taumaha rawa, te ara iahiko poto,
te turuturu o te whenua kotahi-wāhanga me ētahi atu hapa. Ko te kaiwawao hiko
he mahi tiaki mohio me te tiaki whiriwhiri tika, ka taea te whakapai ake
te pono o te tuku hiko, me te karo i ngā motuhanga hiko koretake. I taua wā, kua tuwhera
atanga whakawhitiwhiti momo, he mea watea mō te hononga pahi mara, ā, ka taea te
e whakamahia ana mō ngā mahi mamao e whā hei whakatutuki i ngā whakaritenga o te pokapū whakahaere me
pūnaha aunoa. He rite ki te whakawhiti turuturu e rite ana me te pūnaha atamai
pūmana whakahaere, ka taea te whakatutuki i te tiakitanga turuturu.
Ka taea hoki te whakamahi i te kaiwawao ara iahiko me te iahiko mahi kua whakatauria o te 630A me raro iho mō
taumaha rawa, ara iahiko poto, ngaronga ā-wāhanga, ngaohiko iti me te tiaki whenua o te motuka i roto i te AC
50 (60) Hz, whatunga tohatoha 400V. I raro i te āhua noa, ka taea e te kaiwawao hiko
ka whakamahia hoki mō te whakawhiti auau o te ara iahiko me te tīmatanga auau o te motuka. Ko te ara iahiko
E tutuki ana te kaiwawao i ngā whakaritenga a GB14048.1-2012 mō ngā taputapu whakawhiti me ngā taputapu whakahaere ngaohiko-iti - Wāhanga 1:
Ngā ture whānui; Me GB14048.2-2008 Taputapu whakawhiti me te taputapu whakahaere ngaohiko-iti-Wāhanga 2:
Ngā kaiwawao ara iahiko; GB14048.4-2020 Taputapu whakawhiti me te taputapu whakahaere ngaohiko-iti-Wāhanga4-1:
