Te māramatangaMCBmeRCCBNgā Poraka Hanga Matua mō te Haumaru Hiko
I roto i te mara o ngā whakaurunga hiko, he mea tino nui te haumaru. E rua ngā wāhanga matua e whai wāhi nui ana ki te whakarite i te haumaru hiko ko te Miniature Circuit Breaker (MCB) me te Residual Current Circuit Breaker (RCCB). He rerekē ngā mahi a ēnei taputapu e rua engari he maha ngā wā ka whakamahia ngātahi hei whakarato i te tiakitanga katoa mai i ngā hapa hiko. Ka whakaratohia e tēnei tuhinga he tirohanga hōhonu ki ngā mahi, ngā rerekētanga, me ngā tono o ngā MCB me ngā RCCB, me te whakanui i tō rāua hiranga i roto i ngā pūnaha hiko hou.
He aha te mea he pakaru ara iahiko iti?
He pana aunoa te kaiwawao hiko iti (MCB) e tiaki ana i ngā hiko mai i ngā taumahatanga me ngā pototanga hiko. Ina nui ake te iahiko e rere ana i roto i te hiko i tētahi rohe kua whakaritea, ka motu te MCB, ka aukati i te rere o te iahiko. Mā tēnei ka ārai i te kino pea ki ngā taputapu, ka whakaiti hoki i te tūponotanga o te ahi i puta mai i te wera nui o ngā waea.
Ko te whakatauranga o te MCB e hangai ana ki tōna kaha kawe iahiko, e ahu mai ana i te 6A ki te 63A. Kua hangaia kia taea te tautuhi anō ā-ringa i muri i te pakaru, ā, he mea watea mō ngā pūnaha hiko kāinga me ngā pūnaha arumoni. He mea nui ngā MCB mō te tiaki i ngā ara iahiko takitahi pērā i te rama, te whakamahana me ngā putanga hiko, kia kore ai tetahi hapa i roto i te ara iahiko kotahi e pā ki te pūnaha hiko katoa.
He aha te RCCB?
Ko ngā whati hiko toenga (RCCB), e mōhiotia ana ko ngā taputapu whati hiko toenga (RCD), he mea hanga hei tiaki i te ru hiko me ngā ahi hiko e puta mai ana i ngā hapa whenua. Ka kitea e ia ngā taurite kore i waenga i ngā waea ora me ngā waea kūpapa, ka puta pea ina turuturu te ia ki te whenua, e tohu ana i tētahi hapa pea. Mena ka kitea e te RCCB he rerekētanga o te rere o te ia, ka motuhia i roto i ngā mirihekona ka pakaru te ara iahiko, ka whakaiti nui i te mōrearea o te ru hiko.
He maha ngā whakatauranga e wātea ana ngā RCCB, mai i te 30mA hei tiaki whaiaro ki te 100mA, 300mA rānei hei tiaki ahi. Kāore ngā RCCB e whakarato i te tiaki taumaha, i te tiaki ara iahiko poto rānei; nō reira, he maha ngā wā ka whakamahia ngātahitia me ngā MCB hei whakarite i te haumaru hiko katoa.
Ngā Rerekētanga Matua i waenga i te MCB me te RCCB
Ahakoa he mea nui ngā MCB me ngā RCCB mō te haumaru hiko, he rerekē ā rāua mahi:
1. Momo Parenga: Ka whakarato te MCB i te parenga ki te taumaha me te ara iahiko poto, ka whakarato te RCCB i te parenga ki te hapa whenua me te ru hiko.
2. Tikanga Whakahaere: Ka mahi te kaiwawao hiko iti i runga i te taumata o te iahiko, ā, ka motu ina nui ake te iahiko i te rohe kua whakaritea. He rerekē, ka mahi te RCCB i runga i te mātāpono o te taurite o te iahiko i waenga i ngā waea ora me ngā waea kūpapa.
3. Tikanga tautuhi anō: Ka taea te tautuhi anō i te MCB ā-ringa i muri i te hinganga, engari me tirotiro pea te RCCB me te rapurongoā i mua i te tautuhi anō.
4. Whakamahinga: E whakamahia whānuitia ana ngā MCB hei tiaki i ngā ara iahiko i ngā taiao noho me ngā taiao arumoni, ko ngā RCCB ia he mea nui i ngā wāhi he nui ake te mōrearea o te ru hiko pēnei i ngā kaukau, ngā kīhini me ngā whakaurunga o waho.
Te hiranga o te whakamahi i te MCB me te RCCB
Mō te haumaru hiko tino pai, e taunakihia ana kia whakamahia te MCB me te RCCB i roto i te raupapa. Ka whakaratohia e te MCB te tiaki i te taumaha me te ara iahiko poto, ka whakaratohia e te RCCB te tiaki i te hapa whenua me te ru hiko. Mā tēnei huinga ka tiakina ngā pūnaha hiko mai i ngā momo tūponotanga kino, ā, ka piki ake te haumaru o ngā kaiwhakamahi me ngā rawa.
Hei whakarāpopototanga, he mea nui te mārama ki te mahi a ngā MCB me ngā RCCB mō te hunga katoa e uru ana ki te tāutanga hiko, ki te tiaki rānei. Mā te whakauru i ngā taputapu e rua ki roto i te pūnaha hiko, ka taea te whakaiti i te mōrearea o ngā aituā hiko, ā, ka whakarite kia haumaru ake te taiao mō te katoa. Ahakoa i roto i ngā wāhi noho, i ngā wāhi arumoni, i ngā wāhi ahumahi rānei, ko te whakauru i ngā MCB me ngā RCCB he wāhanga matua o ngā mahi haumaru hiko o ēnei rā.
