Te rerekētanga i waenga i te ACB me te MCCB

Wawahi ara iahiko hau (ACB) mepakaru ara iahiko pouaka whakarewa (MCCB) he taputapu tiaki ara iahiko e rua e whakamahia whānuitia ana i roto i ngā pūnaha hiko. Ahakoa he mahi matua tā rāua ki te tiaki i ngā ara iahiko mai i ngā taumaha rawa, ngā ara iahiko poto, me ētahi atu hapa, he rerekētanga matua kei waenganui i ngā mea e rua e pai ai mō ngā tono rerekē.

Tuatahi, he tino rerekē ngā rahi o ngā ACB me ngā MCCB. He nui ake te rahi me te rahinga o ngā ACB, ā, ko ngā whakatauranga iahiko kei waenga i te 400A ki te 6300A. Nā tēnei ka pai mō te whakamahi i roto i ngā whatunga tohatoha hiko, ko tā rātou mahi he tohatoha i te pūngao hiko me te tiaki i ngā raina me ngā taputapu hiko mai i ngā hapa maha. Ko ngā MCCB, i tētahi atu taha, he iti te rahi me te rahinga, ā, ko ngā whakatauranga iahiko kei waenga i te 10A ki te 800A. He mea noa te whakamahi hei tiaki i ngā raina tohatoha me ngā taputapu mai i ngā taumaha rawa, ngā ara iahiko poto me ngā ngaohiko iti, ā, ka taea hoki te whakarato tiaki mō ngā mahi tīmatanga motuka.

Ko tētahi atu rerekētanga nui i waenga i te ACB me te MCCB ko tā rāua mahi tiaki. He maha ngā mahi tiaki a te kaiwhakawhiti hiko atamai, pērā i te tiaki whakaroa roa, te tiaki whakaroa poto, te tiaki inamata, te tiaki whenua, te tiaki ngaohiko nui, me te tiaki ngaronga ā-wāhanga. Haunga ngā mahi tiaki, ka whakaratohia hoki e te ACB ngā mahi ine pērā i te ine iahiko, te ine ngaohiko, te ine mana, me te ine harmonic, tae atu ki ngā mahi āwhina pērā i te whakatūpato wawe, te tātaritanga-whaiaro, te tuhi hītori hapa, me ngā mahi whakamātautau. Hei tāpiri, kua rite te ACB ki ngā āheinga whakawhitiwhiti kōrero e taea ai te whakauru pai ki roto i te pūnaha hiko whānui. He rerekē, ko ngā kaiwhakawhiti hiko pouaka whakarewa te nuinga e whakarato ana i te tiaki roa, te tiaki poto (tiaki taumaha) me te tiaki inamata (tiaki ara iahiko poto).

He rerekē anō hoki te whānuitanga o te whakamahinga o te ACB me te MCCB. Ko te nuinga o te whakamahinga o te ACB i roto i ngā whatunga tohatoha hiko nui nā te mea he nui te kaha o te iahiko whakatauranga me te whānuitanga o ngā mahi tiaki. He mea nui tā rāua mahi ki te whakarite i te mahi pono me te haumaru o ngā pūnaha hiko mā te ārai i ngā hapa me ngā āhuatanga rerekē. Engari, ko ngā MCCB, e whakamahia ana i roto i ngā taiao arumoni me ngā taiao ahumahi, he nui te kaha o te iahiko whakatauranga iti hei tiaki i ngā taumaha rawa, ngā ara iahiko poto, me ngā ngaohiko iti. He mea noa te whakamahi hei tiaki i ngā raina tohatoha me ngā taputapu, me te whakarato tiaki mō ngā mahi tīmatanga motuka.

Hei whakarāpopototanga, ko ngā rerekētanga i waenga i te ACB me te MCCB ka taea te kī ko ō rāua rahi, ngā mahi tiaki me te whānuitanga o te tono. He nui ake te rahi o te ACB, ā, ka taea e ia te whakarato i ngā mahi tiaki me te ine whānui, ā, he pai hoki mō te whakamahi i roto i ngā whatunga tohatoha hiko, ko te MCCB ia he iti, ā, ka taea e ia te whakarato i ngā mahi tiaki e tika ana mō ngā raina tohatoha me ngā taputapu iti ake. He mea nui te mārama ki ēnei rerekētanga hei whiriwhiri i te taputapu tiaki ara iahiko tika mō tētahi pūnaha hiko, hei whakarite i te mahi tino pai me te haumaru.
