Kia mārama ki te tūranga oMCBi roto i ngā pūnaha hiko
He wāhanga nui ngā pūwā hiko iti (MCB) i roto i ngā pūnaha hiko hou, e whakarato ana i te tiakitanga nui mai i ngā taumahatanga me ngā ara iahiko poto. I te mea kei te tipu haere tonu te hiahia mō ngā taputapu hiko pono me te haumaru, kei te piki haere te hiranga o te mārama ki te mahi me te hiranga o ngā MCB mō ngā tohunga me ngā kaipupuri whare.
He aha te MCB?
Ko te MCB, te kaiwawao ara iahiko iti rānei, he taputapu hiko-ā-ringa i hangaia hei tiaki i te ara iahiko hiko mai i ngā kino i puta mai i te nui o te iahiko. He rerekē ki ngā fiusi tuku iho, me whakakapi i muri i te pakaru, ka taea te tautuhi anō i te MCB i muri i te pakaru, ā, he pai ake, he whai hua ake hoki mō te tiaki ara iahiko. He mea noa te whakamahi i ngā MCB i roto i ngā tono kāinga, arumoni, me ngā tono ahumahi hei tiaki i ngā waea hiko me ngā taputapu hono.
Te mahi a te MCB
E rua ngā mātāpono matua o te whakahaere a ngā MCB: te wehenga wera me te wehenga aukume. Ka aro te tikanga wehenga wera ki te taumaha rawa, ina nui ake te iahiko i te kaha kua whakaritea o te ara iahiko mō tētahi wā. Ka tutuki tēnei mā te rīpene bimetallic, ka piko ina werahia, ā, ka mutu ka puta he pana hei whakatuwhera i te ara iahiko.
Ko ngā tikanga aukume ia, ka aro atu ki ngā ara iahiko poto, arā, he pupūtanga ohorere o te iahiko hiko. I tēnei wā, ka whakaputahia e te aukume hiko he papa aukume kaha e kukume ana i te pana kia tuwhera tata tonu, e ārai ana i te kino pea ki te pūnaha hiko.
Ngā momo MCB
He maha ngā momo MCB, he kaupapa motuhake tā ia momo. Ko ngā momo tino noa ko:
1. Momo MCB B: He pai mō ngā mahi kāinga, ā, ka taea te whakahaere i ngā taumahatanga taurite. Ka piko i waenga i te 3 ki te 5 ngā wā o te iahiko whakatauranga.
2. MCB Momo C: He pai ngā MCB Momo C mō ngā taiao arumoni me ngā taiao ahumahi, ā, ka taea e rātou te whakahaere i ngā iahiko whakauru teitei ake, he mea tino pai mō ngā kawenga hiko whakauru pēnei i ngā motuka. Ka whati rātou i waenga i te 5 me te 10 ngā wā o te iahiko kua whakatauria.
3. MCB Momo-D: Kua hangaia ēnei whati hiko mō ngā mahi taumaha pēnei i ngā whakawhiti hiko me ngā motuka nui, ā, ka taea te whakahaere i ngā iahiko tino nui. Ka whati rātou i te 10 ki te 20 ngā wā o te iahiko kua whakatauria.
Ngā painga o te whakamahi i te MCB
He maha ngā painga o ngā MCB i ngā fiusi tuku iho. Tuatahi, ka taea te whakamahi anō i ngā MCB; ina oti te whakakore i tētahi hapa, ka taea te tautuhi anō me te kore e whakakapi. Ehara i te mea ka penapena wā noa iho tēnei, engari ka whakaitihia hoki ngā utu tiaki. Tuarua, ka tukuna e ngā MCB he tiakitanga tika ake, nā te mea ka taea te whiriwhiri i runga i ngā āhuatanga motuhake o te kawenga e tiakina ana. Mā tēnei ka tiakina ngā taputapu tairongo me te kore e whakararuraru.
Hei tāpiritanga, he pono ake ngā MCB, ā, he tere ake te whati i ngā fiusi, he roa ake te wā e tauhohe ai ki ngā taumahatanga nui. Mā tēnei tauhohenga tere ka whakaitihia te kino o ngā taputapu hiko, ka whakaitihia hoki te tūponotanga o te ahi.
Hei whakarāpopototanga
Hei whakarāpopototanga, he mahi nui tā ngā MCB hei whakarite i te haumaru me te pono o ngā pūnaha hiko. Nā te kaha ki te tiaki i ngā taumahatanga me ngā ara iahiko poto, me te ngāwari hoki ki te whakamahi me te whakamahi anō, ka waiho hei wāhanga nui i roto i ngā tono kāinga me ngā tono ahumahi. I te haere tonu o te whanaketanga o te hangarau, ka piki ake te hiranga o ngā MCB ki te tiaki i ngā taputapu hiko, ā, ka nui ake te mārama ki ō rātou mahi me ngā painga mō te hunga e mahi ana me ngā taputapu hiko. Ahakoa he kaipupuri whare koe e hiahia ana ki te whakapai ake i te haumaru hiko, he tohunga hiko ngaio rānei, he mea nui te mārama ki ngā MCB i roto i te ao hiko o ēnei rā.
