Te māramatangaRCBONgā Huānga Matua o te Haumaru Hiko
I roto i te ao o ngā whakaurunga hiko, he mea tino nui te haumaru. Ko tētahi o ngā wāhanga matua hei whakarite i te haumaru ko te kaiwawao hiko toenga me te tiakitanga iahiko nui, e mōhiotia whānuitia ana ko te RCBO. He mea nui tēnei taputapu ki te tiaki i te tangata me ngā taonga mai i ngā hapa hiko, ā, he wāhanga nui ia o ngā pūnaha hiko hou.
He aha te RCBO?
Ko te RCBO he huinga o ngā taputapu tiaki e rua: he taputapu iahiko toenga (RCD) me te taputapu pakaru ara iahiko iti (MCB). Kua hangaia ngā wāhanga RCD hei kite i ngā hapa whenua, e puta ana ina rere te iahiko ki te whenua i te ara kāore i te whakaarohia. Ka puta pea ngā hapa whenua nā te ngoikore o te whakamarumaru, te makuku, te pā tūpono rānei ki ngā wāhanga ora. Ina kitea he hapa whenua, ka whakatuwherahia e te RCD te ara iahiko hei ārai i te mōrearea o te ru hiko, te ahi rānei.
I tētahi atu taha, ka ārai ngā wāhanga MCB i ngā āhuatanga o te au nui rawa, ka puta mai i ngā taumaha rawa, i ngā ara iahiko poto rānei. Ka puta ngā taumaha rawa ina he maha rawa ngā taputapu e hono ana ki tētahi ara iahiko kotahi, ka nui ake te au i tā te mea ka taea te whakahaere haumaru. Ka puta ngā ara iahiko poto ina he hononga tika i waenga i ngā waea wera me ngā waea kūpapa, ka puta he pikinga ohorere o te au. I ēnei āhuatanga, ka tūtaki te MCB ka whakatuwhera i te ara iahiko, ka ārai i te kino o ngā waea me ngā taputapu.
He aha te take e whakamahia ai te RCBO?
He maha ngā painga o te whakauru i ngā mahi RCD me MCB ki roto i te taputapu kotahi. Tuatahi, ka māmā ake te tukanga tāutanga hiko. Engari ko te tāuta i ngā taputapu motuhake mō te tiaki i te hapa whenua me te au nui, ka whakaratohia e te RCBO ngā mahi e rua i roto i te waeine kotahi kiato. Ehara i te mea ka penapena wāhi noa i roto i te waeine kaihoko, engari ka whakaitihia hoki te wā tāutanga me te utu.
Tuarua, ka whakarei ake ngā RCBO i te haumaru. Mēnā he hapa hiko, ka tere te momotu a ngā RCBO i te ara iahiko, ka whakaiti i te mōrearea o te hiko me te ahi. He mea nui tēnei i roto i ngā taiao noho, he mea nui te haumaru o ngā kainoho. Hei tāpiri, ka taea te whakamahi i ngā RCBO i roto i ngā momo tono, mai i ngā waea whare ki ngā whakaurunga arumoni me ngā whakaurunga ahumahi, ka taea ai te whakamahi me te urutau.
Te whiriwhiri i te RCBO tika
I te wā e whiriwhiri ana i tētahi RCBO, me whai whakaaro ki ētahi āhuatanga. Ko te tuatahi ko te whakatauranga o te au, me ōrite ki ngā whakaritenga kawenga o te ara iahiko. Ko ngā whakatauranga o te au noa ko te 6A, 10A, 16A, 20A me te 32A. He mea nui kia whiriwhiria he RCBO ka taea te whakahaere i te kawenga e tumanakohia ana me te kore e hinga noa.
Ko tētahi atu mea nui ko te whakatauranga o te iahiko toenga, e whakaatuhia ana i roto i ngā milliampere (mA). Ko ngā whakatauranga paerewa ko te 30mA mō te tiaki whaiaro me te 100mA, 300mA rānei mō te tiaki taputapu. Mō ngā tono kāinga, he 30mA te whakatauranga e taunakitia ana hei ārai i te ru hiko.
He mea nui anō hoki kia whakaarohia te momo RCBO. He maha ngā momo hei whiriwhiri māu, pērā i te AC, A, me te B, ia momo i hangaia mō tētahi tono motuhake. He pai te momo AC mō ngā ara iahiko hurihuri, engari ka taea e te momo A te kite i te DC e pupuhi ana, ā, he mea tino pai mō ngā ara iahiko me ngā taputapu hiko. Ka whakamahia te momo B mō ngā ara iahiko he DC maeneene pea, pērā i ngā mea kei roto i ngā whakaurunga rā.
Hei whakarāpopototanga
Hei whakamutunga, he taputapu tino nui ngā RCBO i roto i ngā pūnaha hiko hou, e whakarato ana i te parenga takirua mai i te hapa whenua me ngā āhuatanga o te iahiko nui. Nā te hoahoa kiato, te ngāwari o te tāutanga, me ngā āhuatanga haumaru kua whakarei ake, he mea pai rawa atu ēnei mō ngā kaihanga hiko me ngā kaipupuri whare. I te whanaketanga tonu o ngā paerewa haumaru hiko, kāore e taea te whakanui rawa i te hiranga o te whakauru i ngā RCBO ki roto i ngā taputapu hiko. Mā te mārama me te whakamahi i tēnei wāhanga nui, ka taea e tātou te whakarite i tētahi taiao haumaru ake mō te katoa.
