Te Mārama ki te RCCB: Te Kaiwawao Ara Iahiko Toenga
I te ao o te haumaru hiko, he mahi nui tā ngā pūwā hiko toenga (RCCB) hei tiaki i te tangata me ngā taonga mai i ngā tūponotanga hiko. Kua hangaia ēnei taputapu hei ārai i te ru hiko me te whakaiti i te tūponotanga o ngā ahi hiko i puta mai i ngā hapa whenua. Ka tirohia e tēnei tuhinga te mahi, te hiranga, me ngā tono o ngā RCCB.
He aha te RCCB?
Ko te RCCB (Residual Current Circuit Breaker) he taputapu hiko e momotu ana i te ara iahiko ina kitea he taurite kore i waenga i ngā waea ora (wāhanga) me ngā waea kūpapa. Ko tēnei taurite kore e tohu ana kei te turuturu te iahiko ki te whenua, ka puta pea tēnei i te waea hē, te pakaru o te whakamarumaru, te pā tūpono rānei ki ngā wāhanga ora. Ka aroturuki tonu te RCCB i te iahiko e rere ana i roto i te ara iahiko, ā, ka taea e ia te urupare ki ngā āhuatanga rerekē i roto i ngā mirihekona hei whakarite i te haumaru.
Me pēhea te mahi a te RCCB?
Mā te RCCB e ine te ia e rere ana i roto i ngā waea wera me ngā waea kūpapa. I te nuinga o te wā, me ōrite te ia e rere ana ki roto i te ara iahiko mā te waea wera ki te ia e hoki mai ana mā te waea kūpapa. Mena he rerekētanga, ka kitea e te RCCB tēnei taurite kore.
Ina rongo te RCCB i te ia turuturu, ka whakaoho i tētahi tikanga hei whakatuwhera i te ara iahiko, ā, ka ārai i te ru hiko pea, i te ahi rānei. He rerekē te aro o ngā RCCB, ko ngā whakatauranga iahiko noa ko te 30mA (mō te tiaki whaiaro) me te 100mA, 300mA rānei (mō te tiaki ahi).
Te Hiranga o te RCCB
Kāore e taea te whakanui rawa i te hiranga o ngā RCCB. He arai tino nui rātou mō ngā aituā hiko. Anei ētahi o ngā take matua he mea nui ngā RCCB:
1. Te parenga i te ru hiko: Kua hangaia ngā RCCB hei tiaki i ngā kaimahi mā te momotu i te ara iahiko ina kitea he hapa. He mea nui tēnei i ngā taiao ka pā pea ngā kaimahi ki ngā wāhanga ora.
2. Te Ārai Ahi: Ka taea e ngā hapa hiko te whakawerawera me te ahi. Ka āwhina ngā RCCB ki te ārai i ngā ahi hiko me te tiaki i ngā taonga me te ora mā te kite i ngā ia turuturu ka whakawerawera.
3. Whakatutuki i ngā paerewa hiko: He maha ngā whenua e hiahia ana kia tāutahia ngā pūwhakawhiti hiko toenga (RCCB) ki ngā whare noho me ngā whare arumoni. Mā te whakatutukitanga i ēnei paerewa, ehara i te mea ka whakapai ake i te haumaru anake, engari ka whakarite hoki kia tutuki ngā whakaritenga ture i ngā whakaurunga hiko.
4. Te Rangimarie o te Hinengaro: Mā te tāuta i tētahi kaiwawao hiko toenga (RCCB) ka marino te hinengaro o ngā kaipupuri whare me ngā kaipupuri pakihi. Ka taea e rātou te whakamahi i ā rātou taputapu hiko me te kore e manukanuka ki ngā tūponotanga kino.
Te Whakamahinga o te RCCB
He maha ngā whakamahinga o ngā RCCB, tae atu ki:
- Ngā Whare Noho: I roto i ngā kāinga, ka tāutahia ngā RCCB ki te papa tohatoha matua hei tiaki i ngā ara iahiko e tuku hiko ana ki ngā putanga hiko, rama me ngā taputapu hiko.
- Ngā Wāhi Arumoni: He maha ngā wā ka whakamahia e ngā pakihi ngā RCCB hei tiaki i ngā taputapu me te whakarite i te haumaru o ngā kaimahi me ngā kiritaki.
- Ngā Wāhi Ahumahi: I ngā wāhi ahumahi, he mea nui ngā RCCB hei tiaki i ngā mīhini me ngā kaimahi mai i ngā hapa hiko.
- Tāutanga o waho: Ka whakamahia hoki ngā RCCB i roto i ngā tāutanga hiko o waho pērā i te rama māra me ngā puna kaukau, he nui ake te mōrearea o te ru hiko.
I roto i te poto
He wāhanga nui ngā pūwā hiko toenga (RCCB) o ngā pūnaha hiko hou. He kaha ki te kite me te urupare ki ngā taurite kore hiko, ā, he taputapu haumaru nui ēnei hei tiaki i te ora me ngā taonga mai i ngā tūponotanga o te ru hiko me te ahi. I te whanaketanga o te hangarau me te uaua haere o ngā pūnaha hiko, ka whai wāhi tonu ngā RCCB ki te whakarite i te haumaru hiko i roto i ngā kāinga, i ngā wāhi mahi, me ngā wāhi tūmatanui. Ko te haumi ki ngā RCCB kounga teitei me te whakarite kia tika te tāutanga me te tiaki i a rātou he taahiraa nui ki te taiao hiko haumaru ake.
