He Ruku Hōhonu ki te Pūwhakawhiti Ara Iahiko e Whakahaerehia ana e te Au Toenga (RCBO)

I roto i ngā pūnaha hiko iti-ngaohiko o ēnei rā, he mea nui te haumaru me te pono.Kaiwhatu Ara Iahiko e Whakahaerehia ana e te Au Toenga (RCBO) he taputapu tiaki nui i hangaia hei ārai i ngā tūponotanga hiko pēnei i te ru hiko me ngā ahi i puta mai i ngā hapa hiko. Mā te whakakotahi i te tiaki taumaha, te ara iahiko poto, me te iahiko toenga, ka tukuna e te RCBO he haumaru whānui mō ngā tono maha. I roto i tēnei pou, ka tūhuratia e mātou ngā āhuatanga matua me ngā whakaritenga hangarau o te RCBO me tā rātou mahi ki te tiaki i ngā pūnaha hiko.

Ngā Mahi Matua o te RCBO

Ka whakauruhia e te RCBO ngā tikanga tiaki maha ki roto i te taputapu kotahi. Ko tā rātou mahi matua he kite i ngā taumaha rawa, ngā ara iahiko poto, ngā iahiko toenga rānei (ngā iahiko turuturu) me te momotu tonu i te pūtake hiko hei ārai i ngā kino pea ki te tangata me ngā taonga. Nā tēnei ka tino whai hua ngā RCBO, nā te mea he whānuitia ā rātou whakamahinga, mai i ngā whakaurunga kāinga ki ngā taiao arumoni me ngā taiao ahumahi.

Ngā Whakatakotoranga Hangarau Matua me ngā Āhuatanga

1. Te Awhe o te Iahiko Whakatauranga: He maha ngā momo kōwhiringa iahiko whakatauranga o ngā RCBO hei whakatutuki i ngā tono rerekē. Ko ngā tauira noa pēnei i te CMTB1LE-32 me te CMTB1LE-63 e kapi ana i te awhe iahiko mai i te 3A ki te 63A. Ina koa, kei te wātea te CMTB1LE-32 i roto i ngā whakatauranga o te 3A, 6A, 10A, 16A, 20A, 25A, me te 32A, he mea tino pai mō ngā āhuatanga kawenga māmā ki te waenga. Ko te CMTB1LE-63, i tētahi atu taha, kua hangaia mō ngā kawenga teitei ake, me ngā whakatauranga iahiko o te 40A, 50A, me te 63A, he tino pai mō ngā tono mana teitei ake.

2. Te Kaha Wāwāhi Poto-Ara: Kua hangaia ngā RCBO hei whakakore haumaru i te rere o te iahiko mēnā ka puta he ara poto. Ko te kaha wāwāhi o te tauira CMTB1LE-32 he 6000A, e whakarite ana i te momotu tere ina nui te rere o te iahiko. He rerekē ngā kaha wāwāhi o te CMTB1LE-63 i runga i te whakatauranga o te iahiko: 6000A i te 40A me te 4500A i te 50A me te 63A. Mā ēnei kaha pakari ka pono te RCBO ki te ārai i te kino o ngā taputapu hiko i ngā wā hapa.

3. Ngā Whirihoranga Pou: Ka tukuna e te RCBO te ngāwari ki ngā whirihoranga pou, tae atu ki ngā kōwhiringa 1P+N, 2P, 3P+N, me te 4P, kia taea ai te urutau mō ngā pūnaha hiko kotahi-wāhanga me te toru-wāhanga. Mā tēnei āheinga ka taea te whakamahi i te whānuitanga o ngā tono, me te whakarite kia tiakina ngā ara iahiko mai i te taumaha rawa, ngā ara iahiko poto, me ngā iahiko toenga.

4. Ngā Momo Parenga Au Toenga: E rua ngā momo parenga au toenga e whakaratohia ana e te RCBO—Momo C me te Momo D, i hangaia mō ngā au kua whakatauria i waenga i te 3A me te 63A. He pai te Momo C mō ngā kawenga paerewa, ko te Momo D ia i hangaia mō ngā kawenga hiko-teitei, ngā kawenga kaha-pūmanawa rānei, pērā i ngā motuka, i ngā taputapu ahumahi rānei. Mā tēnei ka taea e te RCBO te whakahaere i ngā momo kawenga maha, ka ārai i te taumaha rawa o te pūnaha, i te kino rānei.

5. Te Tairongo o te Au Toenga: He rerekē ngā taumata tairongo o ngā RCBO ki te au toenga, koinei te āhuatanga matua mō te tiaki i te turuturu. Ko te au mahi toenga whakatauranga (IΔn) he maha ngā kōwhiringa pēnei i te 30mA, 50mA, me te 100mA, kia taea ai e te taputapu te kite i ngā au turuturu me te momotu i te hiko mēnā e tika ana. Hei tāpiri, ko ngā kōwhiringa au kore-mahi toenga whakatauranga (IΔno) o te 15mA, 25mA, me te 50mA ka whakarato i te tika ake hei ārai i te hinganga kāore e hiahiatia me te pupuri tonu i te haumaru.

6. Wā Urupare Tere: Ina kitea he hapa hiko, ka tere tonu te urupare a ngā RCBO, ā, he iti iho i te 0.1 hēkona te wā e kore ai e neke. Mā tēnei urupare tere ka whakaitihia te mōrearea o ngā kino kino, ngā aituā rānei, ka tukuna he tiaki pono puta noa i ngā momo pūnaha hiko rerekē.

Ngā tono RCBO

E whakamahia whānuitia ana ngā RCBO i roto i ngā pūnaha tohatoha ngaohiko iti kāinga, arumoni, me te ahumahi. Nā ngā āhuatanga tiaki whakauru, he mea nui ēnei mō ngā taiao hiko hou, kei reira ngā kawenga kanorau me ngā kawenga uaua.

Mō ngā tono kāinga, ka whakarite te RCBO kia tiakina ngā taputapu hiko o te whare mai i ngā ia turuturu, kia kore ai e tūpono te ru hiko. I ngā wāhi arumoni, ka tiaki te RCBO i ngā taputapu me ngā hanganga nui mai i ngā hapa hiko, kia mau tonu ai te haere tonu o te pakihi. I ngā tono ahumahi, inā koa ka whakamahia ngā taputapu pēnei i ngā motuka me ngā mīhini taumaha, ka whakarato te Momo D RCBO i te tiakitanga pai ake i ngā ia urunga nui ka puta mai me ēnei kawenga hiko.

Whakamutunga

Ko te Pūnaha Whakawātea Ara Iahiko Toenga (RCBO) he wāhanga tiaki matua i roto i ngā pūnaha hiko hou. Mā te whakauru i te tiaki i te taumaha rawa, te ara iahiko poto, me te ara iahiko turuturu, ka tukuna e te RCBO he haumaru pono, whānui hoki. Me ngā āhuatanga pēnei i te kaha pakaru teitei, te kite i te ara iahiko toenga tairongo, me ngā wā urupare tere, ka whakarite ngā RCBO i te pumau me te haumaru o ngā pūnaha hiko i roto i ngā kāinga, ngā pakihi, me ngā taiao ahumahi. Mā te whiriwhiri i te tauira RCBO tika ka whakarite kia mahi pai, kia haumaru hoki ngā pūnaha hiko, kia tiakina ai ngā kaiwhakamahi me ngā taputapu.
