Te mahi a te MCB

I tēnei rā, ka tirohia e tātou ngā mahi uaua ongā whati ara iahiko iti (MCB) me te ako me pēhea tā rātou mahi nui ki te pupuri i te haumaru o ngā ara iahiko me ngā taputapu. He taputapu kiato ngā MCB e tiaki ana i ngā ara iahiko mai i te nui rawa o te au hiko me ngā ara iahiko poto. Kua hangaia hei tiaki i ngā raina me ngā taputapu mai i ngā kino pea mā te whakakore i te rere o te hiko ina neke atu i ngā taumata haumaru. I roto i tēnei tuhinga, ka arotahi mātou ki ngā mātāpono tiaki matua e rua i roto i ngā kaiwawao ara iahiko iti: te tiaki i te nui rawa me te tiaki i te ara iahiko poto, ā, ka tūhuratia me pēhea te mahi tahi o ēnei mātāpono hei pupuri i te mahi haumaru me te whai hua o ngā pūnaha hiko.

Tuatahi, kia mārama tātou ki te kaupapa o te tiaki i te taumaha rawa. Ko te mahi matua o te tiaki i te taumaha rawa ko te aukati i te iahiko i roto i te ara iahiko kei nui ake i tōna kaha kua whakatauhia. Ina nui ake te iahiko i te whakatauranga, ka taea e ia te wera rawa i ngā waea me ngā taputapu, ka puta he tūponotanga ahi nui. Ko te kaupapa o te tiaki i te taumaha rawa i roto i ngā MCB e ahu mai ana i ngā pānga wera. Ina nui ake te iahiko i roto i te ara iahiko i te uara kua whakaritea, ka werahia te wahi bimetallic o te huānga wera i roto i te kaiwawao ara iahiko iti e te iahiko, ka piki ake tōna pāmahana. Kia tae te pāmahana ki tētahi taumata tino nui, ka huri te huānga wera, ka piko ake te bimetal, ka pana i tētahi rīpene hei whakatuwhera i te raka kua raka. Mā tēnei mahi ka pakaru te MCB, ka tapahia te ara iahiko, ka ārai hoki i te iahiko nui kei rere tonu.

Hei te neke atu ki te kaupapa tiaki matua tuarua, he mahi nui tā te tiakitanga ara iahiko poto hei tautuhi tere me te whakaiti i ngā ngaru iahiko ohorere. Ka puta he ara iahiko poto ina piki ohorere te iahiko i roto i te ara iahiko ki ngā taumata tino tiketike, nā te hapa, te ara iahiko poto rānei i waenga i ngā waea. He mōrearea nui tēnei ki ngā taputapu me ngā kaimahi. Kei te MCB he waeine whakamutu hikohiko e kaha ana ki te kite i ngā pikinga tere o te iahiko. Ina kitea he ara iahiko poto, ka hangaia e te tukunga hikohiko he kaha momi kaha e kukume ana i te ejector ka meinga te raka raka kia tuwhera. Ka tapahia tonutia te pūtake hiko hei aukati i ngā iahiko nui kia puta, ka tiakina pai ngā ara iahiko me ngā taputapu mai i ngā kino pea.

Hei whakarāpopototanga, ko ngā mātāpono tiaki e rua, arā, te tiaki i te taumaha rawa me te tiaki i te ara iahiko poto, ka āwhina i te pupuri i te haumaru me te whai hua o te mahi a ngā ara iahiko me ngā taputapu. He wāhanga nui ngā MCB o ngā pūnaha hiko, ā, kua hangaia hei whakarite kia pai te mahi a ngā hanganga hiko, me te whakaiti i ngā mōrearea e pā ana ki te nui o te auhiko me te ara iahiko poto. Mā tōna hoahoa kiato me ngā tikanga tiaki kaha, ka whakaratohia e te MCB he otinga pono me te whai hua mō te tiaki i ngā pūnaha hiko i roto i ngā momo tono, mai i ngā whare noho ki ngā whare ahumahi. Mā te mārama ki ngā mahi uaua o ngā MCB me tā rātou mahi nui ki te tiaki i ngā ara iahiko, ka taea e tātou te whakarite kia haumaru me te roa o te ora o ā tātou hanganga hiko.

Neke atu i te tekau tau te roa o te wheako hanga me te hokohoko a Mutai Group i roto i te...ngā kaiwawao hiko, ngā whakapā, mana takiruangā pana whakawhiti aunoa (ATS) me ngā mara e pā ana. E tino hiahia ana mātou ki te whai wāhi ki te mahi tahi me koe.
