Ngā Rerekētanga me ngā Whakamahinga o te RCCB me te RCBO

Te māramatangaNgā RCCBmeNgā RCBONgā Wāhanga Matua o te Haumaru Hiko

He mea nui te haumaru i roto i ngā whakaurunga hiko. Ko ngā whati hiko toenga (RCCB) me ngā whati hiko toenga me te tiakitanga au nui (RCBO) he taputapu nui e rua e whai wāhi nui ana ki te tiaki i te tangata me ngā taonga. Ahakoa he rite ā rāua whakamahinga, he mea nui te mārama ki ngā rerekētanga me ngā tono o ngā RCCB me ngā RCBO mō te hunga e mahi ana i roto i te taiao hiko, haumaru rānei.

He aha te RCCB?

He taputapu haumaru te kaiwawao hiko toenga (RCCB) i hangaia hei ārai i te ru hiko me ngā ahi hiko i puta mai i ngā hapa whenua. Mā te aroturuki i te taurite o te iahiko e rere ana i roto i ngā waea wera me ngā waea kūpapa ka mahi. Mena ka kitea he taurite o te iahiko (hei tauira, ki te pā tetahi ki te waea wera, tera pea he tohu kei te turuturu te iahiko), ka motu te RCCB i roto i ngā mirihekona ka momotu i te iahiko. He mea nui tēnei urupare tere hei ārai i te whara kino, i te mate rānei.

Ko ngā whati hiko iahiko toenga (RCCB) he mea whakatau i roto i ngā milliampere (mA) ā, e wātea ana i roto i ngā taumata aro, pērā i te 30mA mō te tiaki whaiaro me te 100mA, 300mA rānei mō te tiaki ahi. He mea whakamahi noa ēnei i roto i ngā pūnaha hiko kāinga me ngā pūnaha arumoni hei whakapai ake i te haumaru, inā koa i ngā wāhi he wai, pērā i ngā kaukau me ngā kīhini.

He aha te RCBO?

Ka whakakotahi te RCBO (Residual Current Circuit Breaker with Overcurrent Protection) i te mahi a te RCCB me te miniature circuit breaker (MCB). Ko te tikanga, ehara i te mea ka tiaki noa te RCBO i ngā hapa whenua, engari ka whakarato hoki i te tiakitanga o te overcurrent mai i ngā taumahatanga me ngā ara iahiko poto.

Nā te mahi takirua o te RCBO, he mea whai hua tēnei mō ngā whakaurunga hiko o ēnei rā. Ka taea te whakamahi hei tiaki i ngā ara iahiko takitahi, kia tika ake ai te whakahaere me te haumaru. Hei tauira, ki te puta he hapa i runga i te ara iahiko, ka whati te RCBO, ka wehea taua ara iahiko me te kore e pā ki ētahi atu ara iahiko. He tino whai hua tēnei āhuatanga i roto i ngā taiao noho he maha ngā ara iahiko.

Ngā rerekētanga matua i waenga i te RCCB me te RCBO

Ahakoa he mea nui ngā RCCB me ngā RCBO mō te haumaru hiko, he rerekē rawa ā rāua whakamahinga:

1. Mahi: Ka whakaratohia e te RCCB te tiakitanga hapa whenua anake, ko te RCBO ia ka whakarato i te tiakitanga hapa whenua me te tiakitanga iahiko nui.

2. Whakamahinga: Ko ngā RCCB e whakamahia tahitia ana me ngā MCB, engari ka taea e ngā RCBO te whakakapi i ngā taputapu e rua, ā, ka māmā ake te pūnaha tiaki ara iahiko.

3. Te Utu me te Wāhi: Nā te mea he rua ngā mahi a ngā RCBO, tera pea he nui ake te utu i ngā RCCB. Heoi, nā te mea ka whakakotahihia e ngā RCBO ngā taputapu e rua ki te kotahi, ka taea e rātou te penapena wāhi i roto i te kāpata tohatoha.

4. Tikanga Hīkoi: Ka hē te RCCB ina kitea he kore taurite o te iahiko, engari ka hē te RCBO ina puta he hapa whenua me te iahiko nui.

I roto i te poto

Hei whakarāpopototanga, he wāhanga nui ngā RCCB me ngā RCBO hei whakarite i te haumaru hiko. Ko te nuinga o ngā RCCB ka tiaki i ngā hapa whenua, ka waiho hei taputapu nui i ngā wāhi morearea. I tetahi atu taha, ka whakakotahi ngā RCBO i te tiaki hapa whenua me te tiaki iahiko nui, ka whakarato i tētahi otinga whānui mō ngā pūnaha hiko hou.

I te wā e hoahoa ana, e whakapai ake ana rānei i ngā taputapu hiko, he mea nui kia whakaarohia ngā hiahia taiao me te taumata tiaki e hiahiatia ana. Mā te mārama ki ngā rerekētanga me ngā whakamahinga o ngā RCCB me ngā RCBO ka āwhina i ngā kaimahi hiko me ngā kaipupuri whare ki te whakatau whai whakaaro hei whakapai ake i te haumaru me te pono o ā rātou pūnaha hiko. Ahakoa he RCCB, he RCBO rānei tāu e whiriwhiri ai, ko te whakarite i te haumaru hiko te mea tika tonu.
