Te māramatangaNgā Wāhi Whakamutu Ara Iahiko Toenga RCBOHe Aratohu Whānui
I roto i te mara o te haumaru hiko,Ngā RCBO (ngā kaiwawao iahiko toenga me te tiakitanga iahiko nui)he wāhanga matua ēnei o ngā taputapu hiko hou. Ka whakakotahihia e rātou te mahi a ngā taputapu iahiko toenga (RCD) me ngā kaiwawao iahiko iti (MCB), e whakarato ana i te parenga takirua mai i ngā hapa whenua me ngā āhuatanga iahiko nui. Ka rukuhia e tēnei tuhinga ngā mātāpono whakahaere, ngā painga, me ngā tono o ngā RCBO.
He aha te RCBO?
Kua hangaia ngā RCBO hei tiaki i ngā ara iahiko hiko mai i ngā tūponotanga matua e rua: ngā hapa whenua me ngā taumaha rawa. Ka puta he hapa whenua ina rere te iahiko ki te whenua mā roto i tētahi ara kāore i te whakaarohia, ka puta pea he ru hiko, he ahi rānei. I tētahi atu taha, ka puta he taumaha rawa ina nui ake te iahiko e rere ana i roto i tētahi ara iahiko i tōna kaha kua whakatauhia, ka puta pea he wera nui, ka kino hoki ngā taputapu hiko.
Ka aroturuki tonu te RCBO i te ia e rere ana i roto i te ara iahiko. Mēnā ka kitea he taurite kore i waenga i ngā ara iahiko wera me ngā ara iahiko kūpapa (arā, te iahiko turuturu), ka motuhia, ka momotuhia hoki te ara iahiko. Ka motuhia anō hoki mēnā ka nui ake te iahiko i tētahi rohe kua whakaritea, hei tiaki i te ara iahiko mai i ngā momo hapa e rua.
Ngā āhuatanga matua o RCBO
1. Parenga TakiruaKo te painga matua o te RCBO ko tōna kaha ki te whakarato i te tiaki iahiko toenga me te tiaki iahiko nui i roto i te taputapu kotahi. Mā tēnei ka kore e hiahiatia he RCD me he MCB motuhake, ā, ka māmā ake te pūnaha hiko.
2. Hoahoa KiatoKo ngā RCBO he iti ake te rahi i te whakamahi i ngā taputapu motuhake, ā, ka taea te whakamahi pai ake i te wāhi i roto i ngā waeine kaihoko, i ngā papa tohatoha rānei.
3. Te Whakahekenga KōwhiringaHe maha ngā RCBO kua hangaia me te whiriwhiri i te takahuri, ko te tikanga mēnā he hapa, ko te ara iahiko anake ka momotu. Ka whakarei ake tēnei āhuatanga i te pono o te pūnaha hiko, ā, ka whakaiti i te pokanoa ki ētahi atu ara iahiko.
4. Te Tairongo WhakarerekēHe maha ngā taumata aro o ngā RCBO, mai i te 30mA mō te tiaki whaiaro ki te 100mA, 300mA rānei mō te tiaki taputapu. Mā tēnei ngāwari ka taea te whakarite i te kaupapa tiaki kia rite ki ngā whakaritenga motuhake o te tāutanga.
Te Whakamahinga o te RCBO
He whānuitia te whakamahinga o ngā RCBO i ngā wāhi noho, arumoni, me ngā wāhi ahumahi. I ngā kāinga, he maha ngā wā ka tāutahia ki roto i ngā taputapu hei tiaki i ngā ara iahiko e whakakaha ana i ngā taputapu nui pērā i ngā pouaka whakamātao, ngā mīhini horoi, me ngā pūnaha whakamahana. I roto i ngā whare arumoni, he mea nui ngā RCBO mō te tiaki i ngā taputapu tairongo me te whakarite i te haumaru o ngā kaimahi me ngā kiritaki.
I roto i ngā mahi ahumahi, ka whakamahia ngā RCBO i roto i ngā mīhini e hiahia ana kia tiakina mai i te hapa whenua me te taumaha rawa. Mā te tiaki pono ka āwhina i te karo i te wā kore mahi me te kino o ngā taputapu.
Hei whakarāpopototanga
He mea nui ngā taputapu iahiko toenga RCBO (RCBO) hei whakarite i te haumaru hiko i ngā taiao katoa. Ka whakakotahihia e rātou te mahi a ngā RCD me ngā MCB, ka whakarato i te tiaki whānui mō te hapa whenua me te iahiko nui. Mā te tiaki takirua, te hoahoa kiato, te takahuri whiriwhiri, me te arotau ka taea te whakarite, he otinga maha ngā RCBO mō ngā whakaurunga hiko hou. I te mea he mea nui te haumaru o te pūnaha hiko, he mea nui te mārama me te whakamahi i ngā RCBO hei tiaki i te ora me ngā taonga. Ahakoa i roto i ngā wāhi noho, arumoni, ahumahi rānei, he mea nui ngā RCBO ki te haumaru hiko.
