Ngā Mahi me ngā Rerekētanga i waenga i te MCB me te RCCB

Te māramatangaNgā MCBmeNgā RCCBNgā Wāhanga Matua o te Haumaru Hiko

He mea nui te haumaru i roto i 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 tūhuratia e tēnei tuhinga ngā mahi, ngā rerekētanga, me ngā tono o ngā kaiwawao hiko iti (MCB) me ngā kaiwawao hiko toenga (RCCB), me te whakaatu i tō rāua 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 taumahatanga me ngā pototanga hiko. Ina nui ake te iahiko e rere ana i roto i te hiko i tētahi rohe kua whakaritea, ka motu te MCB, ka aukati i te rere o te iahiko. Mā tēnei ka ārai i te kino pea ki ngā taputapu hiko, ka whakaiti hoki i te tūponotanga o ngā ahi e puta mai ana i te wera nui o ngā waea.

Ka arotakehia ngā MCB mō te iahiko i runga i te kaha kawe iahiko, mai i te 6A ki te 63A te nuinga. He mea hanga kia taea te tautuhi anō ā-ringa i muri i te pakaru, he kōwhiringa watea mō ngā pūnaha hiko kāinga me ngā pūnaha arumoni. He mea nui ēnei mō te tiaki i ngā iahiko takitahi, pērā i te rama, te whakamahana, me ngā putanga hiko, kia kore ai e pāngia te pūnaha hiko katoa e te rahunga kotahi o te iahiko.

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 ara iahiko ora me te ara iahiko kūpapa, ka puta pea nā te korenga o te whakamarumaru, te pā tūpono rānei ki ngā wāhanga ora, ka turuturu 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.

He whānuitia ngā whakatauranga au o ngā RCCB, mai i te 30mA hei tiaki i a koe anō ki te 100mA, 300mA rānei hei tiaki i ngā taputapu. Kāore i rite ki ngā MCB, kāore ngā RCCB e whakarato i te tiaki taumaha, i te tiaki ara iahiko poto rānei, nō reira he maha ngā wā ka whakamahia ngātahitia me ngā MCB i roto i ngā whakaurunga hiko.

Ngā rerekētanga matua i waenga i te MCB me te RCCB

Ahakoa he mea nui ngā MCB me ngā RCCB mō te haumaru hiko, he rerekē ā rāua mahi:

1. Momo Parenga: Ka tiaki te MCB i te taumaha rawa me te ara iahiko poto, ko te RCCB ia ka tiaki i te hapa whenua me te ru hiko.
2. Tikanga Whakahaere: Ka mahi ngā Wāhi Whakamutu Ara Iahiko Iti (MCB) i runga i ngā taumata iahiko, ka mutu te hiko ina nui ake te iahiko i te rohe kua whakaritea. Ka mahi ngā Wāhi Whakamutu Ara Iahiko Toenga (RCCB) i runga i te kore taurite o te iahiko, ka mutu te hiko ina rerekē te iahiko ora me te iahiko kūpapa.
3. Tautuhi Anō: Ka taea te tautuhi anō i te MCB ā-ringa i muri i te hinganga, engari me tautuhi anō pea te RCCB ā-ringa i muri i te whakatau i te hapa.

Te Whakamahinga o te MCB me te RCCB

I ngā wāhi noho me ngā wāhi arumoni, ka whakamahia ngātahitia ngā pakaru hiko iti (MCB) me ngā pakaru hiko toenga (RCCB) hei hanga i tētahi pūnaha tiaki hiko pakari. Hei tauira, i roto i tētahi kāinga noa, ka tāutahia pea ngā MCB ki ngā ara hiko rama me te hiko, ko ngā RCCB ia ka whakamahia pea ki ngā wāhi morearea nui pērā i ngā kaukau me ngā kīhini, he nui ake te tūponotanga o te ru hiko.

I roto i ngā mahi ahumahi, he mea nui ngā MCB me ngā RCCB hei tiaki i ngā mīhini me ngā taputapu mai i ngā hapa hiko, hei whakarite i te haumaru o te mahi me te whakaiti i te wā e kore ai e mahi.

Hei whakamutunga

I roto i ngā kupu poto, he wāhanga nui ngā pakaru hiko iti (MCB) me ngā pakaru hiko toenga (RCCB) o ngā pūnaha haumaru hiko. Ka tiaki ngā MCB i ngā taumahatanga me ngā poto o te hiko, ko ngā RCCB ia ka tiaki i ngā hapa whenua me te ru hiko. He mea nui te mārama ki ngā mahi me ngā tono o ēnei taputapu mō te hunga katoa e uru ana ki te tāutanga hiko, ki te tiaki rānei. Mā te whakakotahi i ngā MCB me ngā RCCB, ka taea e tātou te waihanga i tētahi taiao hiko haumaru ake, me te tiaki i te tangata me ngā taonga mai i ngā tūponotanga o ngā hapa hiko.
