Te māramatangaNgā MCBmeNgā RCCBNgā Wāhanga Matua o te Haumaru Hiko
He mea tino nui te haumaru i roto i te ao o ngā whakaurunga hiko. Ko ngā kaiwawao hiko iti (MCB) me ngā kaiwawao hiko toenga (RCCB) he wāhanga matua e rua hei whakarite i te haumaru hiko. He rerekē ngā whakamahinga o ēnei taputapu e rua engari he maha ngā wā ka whakamahia ngātahi hei whakarato i te tiaki whānui mai i ngā hapa hiko. Ka tirohia e tēnei tuhinga ngā mahi, ngā rerekētanga, me ngā tono o ngā kaiwawao hiko iti (MCB) me ngā kaiwawao hiko toenga (RCCB), ā, ka whakamāramahia tō rātou hiranga i roto i ngā pūnaha hiko hou.
He aha te MCB?
Ko te kaiwawao hiko iti (MCB) he pana aunoa e whakamahia ana hei tiaki i ngā hiko mai i ngā taumaha rawa me ngā poto poto. Ina nui ake te iahiko e rere ana i roto i te hiko i te rohe kua whakaritea, ka motu te MCB ka tapahia te pūtake hiko. Mā tēnei ka ārai i te wera nui me ngā tūponotanga ahi pea e puta mai ana i te iahiko nui rawa. Ko te iahiko whakatauranga o te MCB e whakawhirinaki ana ki tōna kaha kawe iahiko, i waenga i te 6A me te 63A, ā, kua hangaia kia tere te mahi hei whakaiti i te kino ki ngā taputapu me ngā waea.
Ngā whati ara iahiko iti (MCB)He mea nui ēnei i roto i ngā wāhi noho, arumoni, me ngā wāhi ahumahi. He maha ngā wā ka whakamahia i roto i ngā papa whakawhiti hei tiaki i ngā ara iahiko takitahi, kia kore ai e pāngia te pūnaha hiko katoa e te rahunga ara iahiko kotahi. Ka taea te tautuhi anō i ngā whati ara iahiko iti, kia ngāwari ai te whakahoki mai i te hiko i muri i te whakatikatika i te hapa, ā, he kōwhiringa watea mō te tiaki hiko.
He aha te RCCB?
He taputapu ārai hiko toenga (RCCB), e mōhiotia ana ko te taputapu ārai hiko toenga (RCD), kua hangaia hei tiaki i ngā hapa whenua me te ru hiko. Ka kitea he taurite i waenga i ngā waea ora me ngā waea kūpapa, ka puta pea ina pakaru te whakamarumaru, ina pāngia rānei ngā wāhanga ora e te pānga tūpono ki te turuturu o te iahiko ki te whenua. Ina kitea tēnei taurite, ka motuhia e te RCCB te ara iahiko, ka whakaitihia te mōrearea o te ru hiko me te ahi.
Kei te wātea ngā RCCB i roto i ngā taumata aro o te hiko, mai i te 30mA mō te tiaki whaiaro ki te 100mA, 300mA rānei mō te tiaki taputapu. Ko te whiriwhiri i te aro ka whakawhirinaki ki te horopaki tono me te taumata tiaki e hiahiatia ana. Hei tauira, i roto i te taiao noho, ka whakamahia te RCCB 30mA hei tiaki i te tangata mai i te ru hiko, i roto i ngā tono ahumahi, ka taea te whakamahi i te RCCB teitei ake te whakatauranga o te iahiko hei tiaki i ngā taputapu.
MCB me RCCB: Ngā Rerekētanga Matua
Ahakoa he mea nui ngā kaiwawao ara iahiko iti (MCB) me ngā kaiwawao ara iahiko toenga (RCCB) mō te haumaru hiko, he rerekē ā rāua mahi. Ko te rerekētanga matua kei roto i ā rāua tikanga tiaki:
- MCB: Ka ārai i te taumaha rawa me te ara iahiko poto. Kāore e ārai i te hapa whenua, i te ru hiko rānei.
- RCCB: Ka ārai i te hē whenua me te ru hiko. Kāore e ārai i te taumaha rawa, i te ara iahiko poto rānei.
Nā ēnei rerekētanga, he maha ngā wā ka whakamahia ngātahitia ngā kaiwawao hiko iti (MCB) me ngā kaiwawao hiko toenga (RCCB) i roto i ngā whakaurunga hiko. Mā tēnei huinga ka whakaratohia he tiakitanga whānui, ka whakarite i te haumaru o ngā pūnaha hiko me ngā kaiwhakamahi.
Te Whakamahinga o te MCB me te RCCB
I ngā wāhi noho, ka whakamahia ngā kaiwawao hiko iti (MCB) hei tiaki i ngā ara iahiko rama me te hiko, ko ngā kaiwawao hiko toenga iahiko (RCCB) ka tāutahia ki ngā wāhi he nui ake te mōrearea o te ru hiko hei whakapai ake i te haumaru, pērā i ngā wharepaku me ngā kīhini. I ngā wāhi arumoni me ngā wāhi ahumahi, he mea nui ngā taputapu e rua hei tiaki i ngā mīhini me te whakarite i te haumaru o ngā kaimahi.
Hei whakarāpopototanga, he wāhanga nui o tētahi pūnaha haumaru hiko ngā kaiwawao hiko iti (MCB) me ngā kaiwawao hiko toenga (RCCB). He mea nui te mārama ki ā rātou mahi me ā rātou tono mō te hunga katoa e uru ana ki te tāutanga hiko, ki te tiaki rānei. Mā te whakakotahi i ngā kaiwawao hiko iti (MCB) me ngā kaiwawao hiko toenga (RCCB), ka taea te hanga i tētahi kupenga haumaru kaha hei tiaki i ngā momo tūponotanga hiko, kia pai ai te taiao mō te katoa.
