Te māramatangaNgā Wāhi Whakamutu Ara Iahiko ToengaHe Aratohu Whānui
I te ao o te haumaru hiko, he mea nui ngā pūwā hiko toenga (RCCB) hei tiaki i te tangata me ngā taonga mai i ngā hapa hiko. Kua hangaia ēnei taputapu hei kite i ngā taurite o te iahiko me te momotu i te ara iahiko hei ārai i te ru hiko me te ahi pea. I roto i tēnei tuhinga, ka rukuhia e mātou ngā mahi, ngā painga, me te hiranga o ngā RCCB i roto i ngā pūnaha hiko hou.
He aha te mea he whati ara iahiko toenga?
Ko te taputapu aukati iahiko toenga (RCD), e mōhiotia whānuitia ana ko te taputapu iahiko toenga (RCCB), he taputapu hiko e whakamahia ana hei aroturuki i te iahiko i roto i te ara iahiko. Ka whakataurite tonu i te iahiko e rere ana i roto i te ara iahiko ora (wāhanga) me te iahiko e rere ana i roto i te ara iahiko kore. I te nuinga o te wā, me ōrite ēnei iahiko e rua. Heoi, ki te puta he hapa, pērā i te ara iahiko poto, i te hapa ārai rānei e puta ai te iahiko turuturu, ka kitea e te RCCB te rerekētanga i waenga i ngā mea e rua—te iahiko toenga. Ina neke atu tēnei tauritekore i tētahi paepae kua whakaritea, ka motu te RCCB, ka momotu i te pūtake hiko, ā, ka ārai i te kino o ngā taputapu.
Me pēhea te mahi a te RCCB?
Ko te kaupapa o te mahi a ngā RCCB he whakapūnga hiko hiko. Kei roto i te taputapu he matua aukume e takai ana i ngā waea ora me ngā waea kūpapa. Ina taurite ngā ia, ka whakakorea ngā papa aukume e whakaputaina ana e ēnei ia. Heoi, ki te mea he ia turuturu, ka kore taurite ngā papa aukume, ka puta he ia ki roto i te matua, ka tīmata te tikanga whakataka. Mā tēnei urupare tere (i roto i te 30 mirihekona te nuinga) ka momotu te ara iahiko i mua i te puta o tētahi kino nui.
Ngā painga o te whakamahi i te RCCB
1. Te whakapai ake i te haumaru: Ko te painga matua o ngā RCCB ko tō rātou ārai i te ru hiko. He tino whai hua ngā RCCB i ngā taiao mākū pērā i ngā kaukau me ngā kīhini, he nui ake te mōrearea o te ru hiko.
2. Te Ārai Ahi: He mahi nui tā ngā RCCB ki te ārai ahi mā te kite i ngā rerenga wai e turuturu ana ka wera rawa, ka mura pea. Ka āwhina rātou ki te whakaiti i ngā mōrearea e pā ana ki ngā hapa o ngā waea me ngā taputapu hiko.
3. Kia tutuki ngā ture: He maha ngā ture haumaru hiko me ngā ture hanga whare e hiahia ana kia tāutahia ngā pūwhakaweto iahiko toenga (RCCB) i roto i ngā whare noho me ngā whare arumoni. Mā te whakamahi i ēnei taputapu ka tutuki ngā ture, ā, ka whakapai ake i ngā paerewa haumaru whānui.
4. Ngāwari te tāuta me te tiaki: He tino ngāwari te tāuta i te RCCB, ā, he iti noa ngā utu tiaki. E taunakihia ana kia whakamātauria i ia wā mā te whakamahi i te pātene whakamātautau kia mōhio ai kei te mahi tika.
Te whiriwhiri i te RCCB tika
I te wā e whiriwhiri ana i tētahi RCCB, me whai whakaaro ki ngā āhuatanga e whai ake nei:
- Iahiko Whakatauranga: Koinei te iahiko mōrahi ka taea e te RCCB te tu atu. Me whiriwhiri te iahiko whakatauranga i runga i te kawenga katoa o te ara iahiko e tiakina ana e ia.
- Taumata Tairongo: He rerekē ngā taumata tairongo o ngā RCCB, ko te tikanga he 30mA mō te tiaki whaiaro me te 100mA, 300mA rānei mō te tiaki ahi. Ko te kōwhiringa ka whakawhirinaki ki te tono motuhake me te taumata mōrearea.
- Te maha o ngā pou: Kei te wātea ngā RCCB i roto i ngā whirihoranga pou-kotahi, pou-rua me ngā pou-whā, i runga i te momo ara iahiko e tiakina ana.
I roto i te poto
Hei whakarāpopototanga, he wāhanga nui ngā kaiwawao hiko toenga o ngā pūnaha hiko hou, e whakarato ana i te tiaki nui mai i te ru hiko me te ahi. Nā te kaha ki te kite wawe me te urupare ki ngā taurite hiko, he mea nui ēnei hei taputapu haumaru i roto i ngā kāinga me ngā pakihi. I te whanaketanga tonu o ngā paerewa haumaru hiko, ka nui haere te hiranga o ngā kaiwawao hiko toenga, ā, ka waiho hei haumitanga nui mā te hunga e hiahia ana ki te whakarei ake i ā rātou mahi haumaru hiko.
