Te māramatangaRCCBmeRCBONgā 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. Ka mahi mā te aroturuki i te taurite o te ia e rere ana i roto i ngā waea wera me ngā waea kūpapa. Mena ka kitea he taurite o te ia, e tohu ana pea i te ia turuturu (hei tauira, mena ka pā tetahi ki te waea wera), ka whati te RCCB i roto i ngā mirihekona ka momotu i te ia. 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 hē te mahi a tētahi taputapu, ara iahiko rānei, ka tū te RCBO, ka wehea te hapa, engari kāore e pā ki te pūnaha hiko katoa. 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 ā rāua mahi:
1. Te whānuitanga o te tiakitanga: Ka whakaratohia e te RCCB te tiakitanga hapa whenua anake, engari ko te RCBO ka whakarato i te tiakitanga hapa whenua me te au nui (te taumaha me te ara iahiko poto).
2. Whakamahinga: Ko te RCCB e whakamahia tahitia ana me te MCB hei whakarato i te tiakitanga whānui, ko te RCBO ia ka taea te whakamahi motuhake hei tiaki i tētahi ara iahiko kotahi.
3. Tāutanga: Ka nui ake te wāhi e pau ana i te tāutanga o te RCCB me te MCB i roto i te papa tohatoha, ā, ka taea e te RCBO te whakakotahi i ngā mahi e rua ki roto i te taputapu kotahi, ā, ka penapena wāhi.
Te whiriwhiri i waenga i te RCCB me te RCBO
I te wā e whiriwhiri ana koe i waenga i te RCCB me te RCBO, whakaarohia ngā hiahia motuhake o tō pūnaha hiko. Mena kei te hiahia koe ki te tiaki i te whenua, ā, kua tāuta kētia he MCB, he rawaka pea te RCCB. Heoi, mō ngā tāutanga hou, mō te whakapai ake rānei i ngā pūnaha o nāianei, ko te tikanga he RCBO te mea e taunakitia ana nā ō rātou āhuatanga tiaki whānui me te hoahoa penapena wāhi.
I roto i te poto
Hei whakarāpopototanga, he wāhanga nui ngā RCCB me ngā RCBO mō te haumaru hiko. Mā te mārama ki ā rāua mahi, ki ō rāua rerekētanga, me ā rāua whakamahinga ka āwhina i a koe ki te whakatau whai whakaaro i te wā e hoahoa ana, e whakapai ake ana rānei i tō pūnaha hiko. Ahakoa he kaipupuri whare koe, he tohunga hiko, he tohunga haumaru rānei, mā te whakatairanga i te whakamahinga o ēnei taputapu ka taea te whakaiti i te tūponotanga o ngā tūponotanga hiko, kia pai ake ai te taiao mō te katoa.
