Me pēhea te whiriwhiri i te RCBO tika: Te kaiwawao ara iahiko turuturu whenua me te tiaki taumaha
Me pēhea te whiriwhiri i te RCBO tika: Te kaiwawao ara iahiko turuturu whenua me te tiaki taumaha
Mō te haumaru hiko, he mea nui te haumi ki ngā taputapu tika. Ko te kaiwawao hiko toenga (RCBO) me te tiaki i te taumaha rawa tētahi o aua taputapu e whai wāhi nui ana ki te tiaki i ngā pūnaha hiko me te ārai i te ru hiko. Ka whakakotahi ngā RCBO i ngā mahi a te taputapu iahiko toenga (RCD) me te kaiwawao hiko iti (MCB) hei whakarato tiaki matatau ki ngā hapa hiko.
He mea nui te whiriwhiri i te RCBO tika mō tō tono kia pai ai te haumaru me te mahi. Anei ētahi āhuatanga hei whakaaroaro māu i te wā e whiriwhiri ana i te RCBO:
1. Iahiko kua whakatauria: Me ōrite te iahiko kua whakatauria o te RCBO ki te kaha iahiko mōrahi o te pūnaha hiko. Ka rerekē pea tēnei uara i runga i te rahi o te ara iahiko me ngā taputapu e whakakahangia ana e ia. He mea nui kia whiriwhiria he RCBO me te iahiko e tika ana mō ō hiahia motuhake kia kore ai e wera rawa, e hē rānei.
2. Te Tairongo: Ka inehia te tairongo o te RCBO i roto i ngā milliampere (mA) ā, ka whakatau i te taumata o te kore taurite o te iahiko e hiahiatia ana hei whakaweto i te taputapu. Ko te iti o te tairongo, ko te tere ake o te urupare a te RCBO ki ngā hapa morearea. Mō ngā tono kāinga, ko te tairongo o te 30mA te tikanga e taunakitia ana. Heoi, i ētahi taiao ahumahi, me teitei ake pea te tairongo.
3. Momo: He maha ngā momo RCBO, pērā i te momo AC, te momo A, te momo F, te momo B, me ētahi atu. He rerekē ngā taumata tiaki o ia momo. He pai te momo AC mō te nuinga o ngā tono kāinga, ā, ka tiaki i te pā ā-korekore me ngā tūponotanga ahi. He tairongo ake te momo A, ka tiaki i te pā ā-korekore me te pā ā-korekore, me te tiaki atu anō hoki i ngā hapa o te au tika (DC). Ka tiaki pai ake te momo F i ngā tūponotanga ahi, ā, he pai mō ngā tono ahumahi motuhake. Hei whakamutunga, ka tiaki te momo B i ngā momo hapa katoa, tae atu ki ngā au DC maeneene.
4. Kaihanga me te Tiwhikete: Kōwhiria te RCBO i hangaia e tētahi kamupene rongonui e mōhiotia ana mō tōna whakapau kaha ki te kounga. Rapua ngā tiwhikete pēnei i ngā paerewa a te International Electrotechnical Commission (IEC) me te whakamanatanga mai i ngā taiwhanga whakamātautau motuhake hei whakarite kia tutuki i te RCBO ngā paerewa haumaru kua whakamanahia.
5. Ngā āhuatanga tāpiri: I runga anō i ō hiahia, whakaarohia ngā āhuatanga tāpiri pēnei i te parenga ara iahiko-poto, te parenga iahiko-nui, me te parenga ngaru hiko. Ka whakaratohia e ēnei āhuatanga tāpiri he haumarutanga me te whai wāhitanga anō hoki.
Hei whakarāpopototanga, he mea nui te whiriwhiri i te RCBO tika mō tō pūnaha hiko kia pono ai te tiaki hiko. Mā te whakaaro ki ngā āhuatanga pēnei i te whakatauranga ampere, te aro, te momo, te ingoa o te kaihanga, ngā tiwhikete, me ngā āhuatanga tāpiri, ka taea e koe te whakatau whai whakaaro e whakamana ana i te haumaru me te mahi tino pai. Whakapau moni ki tō haumaru hiko mā te whiriwhiri i te RCBO tika.
