He mea nui ngā parenga hiko iti (MCB) me ngā parenga hiko pouaka pokepoke (MCCB) i roto i ngā pūnaha hiko e whakamahia ana hei tiaki i ngā taumaha rawa, ngā ara iahiko poto, me ētahi atu hapa. Ahakoa he rite te kaupapa, he rerekē tonu ētahi o ngā mea e rua e pā ana ki te kaha, ngā āhuatanga takahi, me te kaha pakaru.

Pūwhakapakari Arahiko Iti (MCB)

A Pūwhakawhiti hiko iti (MCB)He taputapu hiko iti te hiko e whakamahia ana hei tiaki i ngā ara iahiko mai i ngā ara iahiko poto me ngā taumaha rawa. He mea whakamahi noa i roto i ngā whakaurunga hiko i roto i ngā whare noho me ngā whare arumoni, ā, kua hangaia hei tiaki i ngā ara iahiko takitahi kaua ki ngā pūnaha hiko katoa.

Pakaru ara iahiko pouaka whakarewa (MCCB)

A Kaiwhakamutu Arahiko Kua Whakarewahia (MCCB)he mea pakaru hiko nui ake, he mea pakari ake hoki, e whakamahia ana hoki hei tiaki i ngā hiko mai i ngā poto o ngā hiko, ngā taumaha rawa, me ētahi atu hapa. Kua hangaia ngā MCCB mō ngā whakatauranga ngaohiko me te iahiko teitei ake mō ngā tono arumoni, ahumahi me ngā tono whare noho nui.

Ngā Rerekētanga Matua i waenga i te MCCB me te MCB

Hanganga:He iti ake te rahi o ngā MCB i ngā MCCB. He rīpene whakarewa rua te MCB e piko ana ina neke atu te iahiko i tētahi paepae, ka whakaoho i te MCB, ka whakatuwhera hoki i te ara iahiko. Engari he uaua ake te hanganga o te MCCB. Ka whakamahia he tikanga hikohiko hei whakaoho i te ara iahiko ina neke atu te iahiko i tētahi paepae. Hei tāpiri, he parenga aukume wera kei te MCCB hei tiaki i te taumaha rawa me ngā ara iahiko poto.

Te kaha:Ko ngā MCB e whakamahia ana mō ngā whakatauranga iahiko me te ngaohiko iti iho i roto i ngā whare noho me ngā whare arumoni. I te nuinga o te wā tae atu ki te 1000V me ngā whakatauranga i waenga i te 0.5A me te 125A. Kua hangaia ngā MCCB mō ngā tono ahumahi me ngā tono arumoni nui, ā, ka taea te whakahaere i ngā iahiko mai i te 10 amps ki te 2,500 amps.

Te kaha pakaru:Ko te kaha pakaru te nui rawa o te iahiko hapa ka taea e te kaiwawao hiko te motu me te kore e pakaru. Ki te whakatauritea ki te MCB, he nui ake te kaha pakaru o te MCCB. Ka taea e ngā MCCB te whakakore i ngā iahiko tae atu ki te 100 kA, ko ngā MCB ia ka taea te whakakore i te 10 kA, iti iho rānei. Nō reira, he pai ake te MCCB mō ngā tono he nui te kaha pakaru.

Ngā Āhuatanga Tūtaki:Ko te painga o te MCCB me te MCB ko te tautuhinga haerenga ka taea te whakarite. Mā te MCCB ka taea te whakarite takitahi i te ia o te haerenga me te whakaroa wā kia pai ake ai te tiaki i ngā pūnaha hiko me ngā taputapu. He rerekē, he tautuhinga haerenga pumau ā ngā MCB, ā, he mea hanga kia wehea i tētahi uara ia motuhake.

Utu:He nui ake te utu o ngā MCCB i ngā MCB nā te rahi, ngā āhuatanga mahi, me ērā atu. Ko te nuinga o ngā MCCB he nui ake te kaha me ngā tautuhinga haerenga ka taea te whakarerekē. Ko ngā MCB he kōwhiringa iti ake te utu mō te tiaki i ngā pūnaha hiko me ngā taputapu iti.

Whakamutunga

Hei whakarāpopototanga, he mea nui te mahi a ngā MCCB me ngā MCB ki te tiaki i ngā ara iahiko mai i ngā ara iahiko poto, ngā taumaha rawa, me ētahi atu hapa i roto i ngā pūnaha hiko. Ahakoa he rite ngā mahi, ngā kaupapa rānei o ngā mea e rua, he rerekē tonu te whakamahinga. He pai ake ngā MCCB mō ngā pūnaha hiko nui me ngā whakaritenga au nui, ko ngā MCB ia he iti ake te utu, ā, he pai ake mō te tiaki i ngā pūnaha hiko me ngā taputapu iti ake. Mā te mōhio ki ēnei rerekētanga ka āwhina koe ki te whiriwhiri i te kaiwawao ara iahiko tika mō ō hiahia motuhake, me te whakarite kia noho haumaru, kia whai hua hoki tō pūnaha hiko.
