Te Mārama ki ngā RCCB Hiko: He Aratohu Whānui
I te ao o te haumaru hiko, he mea nui te mahi a ngā kaiwawao hiko toenga (RCCB) hei tiaki i te tangata me ngā taonga mai i ngā tūponotanga hiko. Ka rukuhia e tēnei tuhinga te tikanga, te mahi, me ngā tono o ngā RCCB hiko, kia mārama ai ki tēnei taputapu nui.
He aha te RCCB?
Ko te RCCB, e mōhiotia ana ko te taputapu iahiko toenga (RCD), he taputapu haumaru e whakamahia ana hei ārai i te ru hiko me ngā ahi hiko e puta mai ana i ngā hapa whenua. Ka mahi mā te aroturuki i te taurite o te iahiko e rere ana i roto i ngā waea wera me ngā waea kūpapa o te ara iahiko. Mena ka kitea he taurite kore o te iahiko (ka puta pea ina turuturu te iahiko ki te whenua), ka momotu wawe te RCCB i te ara iahiko, ka whakaiti i te mōrearea o te ru hiko me te ahi.
Me pēhea te mahi a te RCCB?
Ka mahi ngā RCCB i runga i te ia rerekētanga. I te nuinga o te wā, me rite te ia e rere ana i roto i te kaiārahi ora ki te ia e rere ana i roto i te kaiārahi kūpapa. Heoi, ki te puta he hapa, pērā i te pā o te tangata ki te kaiārahi ora, te pakaru rānei o te taputapu, ka rere pea ētahi o te ia ki te whenua. Ka taea e te RCCB te kite i tēnei rerekētanga (e 30 milliamperes (mA) te nuinga) ka pakaru i roto i ngā milliseconds.
He mea nui tēnei urupare tere hei ārai i ngā whara kino, i te mate rānei i te ru hiko. Kei te wātea ngā RCCB i roto i ngā momo whakatauranga o nāianei, tae atu ki te 30mA mō te tiaki whaiaro me te 100mA, 300mA rānei mō te tiaki ahi, e āhei ai ngā kaiwhakamahi ki te whiriwhiri i te taputapu e tika ana mō ā rātou hiahia.
Ngā momo RCCB
He maha ngā momo RCCB hiko, he rerekē te kaupapa o ia momo:
1. RCCB pou-rua: E whakamahia ana mō ngā ara iahiko kotahi-wāhanga, e rua ōna pito mō ngā hononga ora me te hononga kūpapa.
2. RCCB 4-pou: I hangaia mō ngā ara iahiko toru-wāhanga, e whā ngā pito hei whakauru i ngā wāhanga e toru me tētahi ara iahiko kūpapa.
3. Momo AC RCCB: Ka kitea te iahiko toenga o te au hurihuri (AC).
4. Momo A RCCB: Ka taea te kite i ngā iahiko toenga AC me te DC e pupuhi ana, he pai mō ngā ara iahiko me ngā taputapu hiko.
Te Whakamahinga o te RCCB
He whānuitia te whakamahinga o ngā RCCB i ngā wāhi noho, arumoni, me ngā wāhi ahumahi. I ngā kāinga, ka tāutahia ēnei ki te papa tohatoha matua hei tiaki i ngā ara iahiko e whakakaha ana i ngā taputapu, rama, me ngā putanga hiko. I ngā whare arumoni, ka tiakina ngā taputapu e ngā RCCB, ā, ka noho haumaru hoki ngā kaimahi me ngā kiritaki. I ngā wāhi ahumahi, he mea nui ēnei mō te tiaki i ngā mīhini me te ārai i te wā utu nui o te korenga hiko nā ngā hapa hiko.
Ngā painga o te whakamahi i te RCCB
He maha ngā painga o te tāutanga o tētahi RCCB hiko:
- Haumarutanga Whakapai Ake: Ka whakaitihia e ngā RCCB te mōrearea o te ru hiko me te ahi, ka marino ai te hinengaro o ngā kaiwhakamahi.
- Te Whakatutukitanga i ngā Ture: He maha ngā paerewa haumaru hiko me ngā waehere hanga e hiahia ana kia tāutahia he RCCB i roto i ngā tono motuhake hei whakarite i te tutuki i ngā ture me te haumaru.
- Te Tiakitanga Whai Hua: Ahakoa he haumitanga tuatahi e hiahiatia ana hei hoko me te tāuta i tētahi RCCB, he nui ngā penapena mō te wā roa mai i te ārai i ngā aituā me ngā kino o ngā rawa.
Hei whakarāpopototanga
He whakarāpopototanga noa iho, he wāhanga nui ngā RCCB i roto i ngā pūnaha hiko hou, e whakarato ana i te tiaki nui mai i ngā tūponotanga hiko. Mā te mārama ki ā rātou mahi, momo, me ngā whakamahinga ka āwhina i ngā tāngata takitahi me ngā pakihi ki te whakatau kaupapa haumaru hiko whai whakaaro. Mā te whakauru i ngā RCCB ki roto i ngā whakaurunga hiko, ka taea e ngā kaiwhakamahi te whakarei ake i te haumaru, te whai i ngā ture, ā, hei whakamutunga, te tiaki i te ora me te taonga mai i ngā tūponotanga o ngā hapa hiko. I te haere tonu o te whanaketanga o te hangarau, ka piki haere te hiranga o ngā RCCB ki te whakarite i te haumaru hiko, ka waiho hei wāhanga nui o tētahi pūnaha hiko.
