Ngā horopaki tono o te RCCB

He mea nui ngā āhuatanga tono o ngā kaiwawao hiko toenga (RCCB) hei whakarite i te haumaru o te tangata me ngā taonga. I mua i te ruku hohonu ki ngā āhuatanga tono motuhake, he mea nui kia mārama ki ngā mātāpono taketake o te ru hiko me te tūranga o te RCCB ki te aukati i te ru hiko.

He whara kino te ru hiko e puta mai ana i te rerenga o te iahiko hiko i roto i te tinana o te tangata. Ina pā ngā ringa o te tangata ki tētahi waea ora, ka rere te hiko i roto i te tinana, ka pāngia pea. I muri i te pānga o te ru hiko, me motu te iahiko i te wā e taea ai. Ko te rohe wā mō te motu i te iahiko e whakawhirinaki ana ki te nui o te iahiko e rere ana i roto i te tinana. Hei tauira, mēnā he 50mA te iahiko, me noho te wā mutu i roto i te 1 hēkona. Mēnā he 500mA te iahiko, ka whakapotohia te wā mutu ki te 0.1 hēkona.

A Kaiwhatu Ara Iahiko Toenga (RCCB) he taputapu haumaru hiko i hangaia hei momotu aunoa i te pūtake hiko mēnā ka turuturu te iahiko, ka pā mai rānei te ru hiko. Ina tae te iahiko ki te uara iahiko whakahaere i whakatakotoria e te pana tiaki, ka motuhia e te RCCB te pūtake hiko i roto i tētahi wā poto hei whakarite i te haumaru o te tangata me ngā taonga. Nā tēnei ka waiho te RCCB hei wāhanga nui o te haumaru hiko i roto i ngā momo horopaki tono.

He rerekē ngā āhuatanga whakamahinga o te RCCB, ā, he whānui te whānuitanga o ngā āhuatanga. Ko tētahi o ngā āhuatanga matua ko ngā raina tohatoha mō ngā taputapu hiko ringaringa me ngā taputapu pūkoro, tae atu ki ngā taputapu pumau e kore e taea e te tangata te mawhiti atu i te wā tika mēnā ka pāngia e te hiko. Hei tāpiri, me whakauru ngā taputapu hiko i ngā wāhi mahi o waho me ngā ara iahiko taputapu whare, ngā ara iahiko putanga rānei ki ngā RCCB me te uara iahiko mahi toenga kua whakatauria kāore e neke ake i te 30mA. Mā tēnei ka tiakina te tangata mai i ngā tūponotanga ohorere hiko i roto i ēnei taiao.

Ko tētahi atu āhuatanga whakamahinga nui o te RCCB ko te rama o te pou ararewa e whakakahangia ana e te AC 220V. I tēnei wā, ko te ngaohiko hiko tino pai mō te rama o te pou ararewa ko te 36V. Heoi, ina whakamahia te AC 220V, me tāuta he RCCB hei whakarato i te tiakitanga tāpiri. Hei tāpiri, me whai taupoki tiaki te pūtake rama hei whakaiti i te mōrearea o te ru hiko.

Hei whakarāpopototanga, he mea nui ngā āhuatanga tono o ngā kaiwawao hiko toenga (RCCB) hei ārai i te ru hiko me te whakarite i te haumaru o te tangata me ngā taonga. Mai i ngā taputapu hiko ringaringa me ngā taputapu pūkoro ki ngā hiko o ngā taputapu whare me te rama o te pou ararewa, he mahi nui tā ngā RCCB ki te ārai i ngā pānga kino o te ru hiko. Mā te mārama me te whakatinana i ngā āhuatanga tono tika mō te RCCB, ka taea e ngā tāngata takitahi me ngā whakahaere te waihanga i tētahi taiao haumaru ake, me te whakaiti i te mōrearea o ngā aituā hiko.
