Te Mārama ki ngā Wāwāhi Ara iahiko McB: He Aratohu Whānui
I te ao o te hangarau hiko me te haumaru, he mahi nui tā ngā kaiwawao hiko iti (MCB) hei tiaki i ngā hiko mai i ngā taumahatanga me ngā pototanga. He mea nui ēnei taputapu mō ngā pūnaha hiko kāinga me ngā pūnaha arumoni, hei tiaki i ngā taputapu me ngā waea mai i ngā kino ka puta mai i te nui o te hiko.
He aha te mea he pakaru ara iahiko McB?
He pana aunoa te pūtahuri hiko MCB e whakakore ana i te rere o te iahiko i roto i te ara iahiko ina kitea he āhuatanga rerekē, pērā i te taumaha rawa, te ara iahiko poto rānei. He rerekē ki ngā fiusi tuku iho, me whakakapi i muri i te pakaru, ka taea te tautuhi anō i ngā pūtahuri hiko MCB i muri i te pakaru, ā, he kōwhiringa watea ake, he whai hua ake hoki mō te tiaki ara iahiko.
Me pēhea te mahi a te pūwhakawhiti ara iahiko McB?
Ko te mahi a ngā whati ara iahiko Mcb e hangai ana ki ngā tikanga matua e rua: te wera me te aukume.
1. Tikanga wera:Ka aro atu tēnei wāhanga ki ngā āhuatanga taumaha rawa. Ina nui ake te ia e rere ana i roto i te ara iahiko i te kaha kua whakaritea o te kaiwawao ara iahiko, ka piko te rīpene whakarewa-rua i roto i te kaiwawao ara iahiko nā te wera i puta. Kia tae te piko ki tētahi taumata, ka whakaoho te rīpene whakarewa-rua i te tikanga wawahi ara iahiko, ka mutu ai te iahiko.
2. Tikanga AukumeKua hangaia tēnei tikanga hei urupare ki ngā ara iahiko poto. Ina puta he ara iahiko poto, ka tere te piki o te iahiko, ka puta he papa aukume kaha e kukume ana i te rīwhi, ka tere tonu te whati o te kaiwawao ara iahiko. He mea nui tēnei urupare tere hei ārai i te kino o ngā wāhanga hiko me te whakaiti i te mōrearea o te ahi.
Momo pakaru ara iahiko Mcb
He maha ngā momo o ngā whati ara iahiko McB, ia momo i hangaia mō tētahi kaupapa motuhake:
Momo BMō ngā whakamahinga kāinga, ka pakaru tēnei momo whati hiko i te 3 ki te 5 ngā wā o te iahiko kua whakatauria. He tino pai mō ngā hiko me ngā kawenga ātete, pērā i te rama me te whakamahana.
Momo CKua hangaia tēnei momo mō ngā tono arumoni me ngā tono ahumahi, me te ia o te rerenga o te 5 ki te 10 ngā wā o te ia kua whakatauria. He pai mō ngā ara iahiko me ngā kawenga ā-whakauru, pērā i ngā motuka me ngā whakawhiti hiko.
Momo DKa whakamahia tēnei momo i roto i ngā tono he nui te rerenga hiko e tomo mai ana, pērā i ngā motuka nui me ngā whakawhiti hiko. Ka whati i te 10 ki te 20 ngā wā o te iahiko kua whakatauria.
Ngā painga o te whakamahi i ngā whati ara iahiko Mcb
1. HaumaruHe huarahi pono ngā whati hiko McB hei tiaki i ngā hiko mai i ngā taumaha rawa me ngā poto o ngā hiko, ā, ka tino whakaiti i te tūponotanga o ngā ahi hiko me te kino o ngā taputapu.
2. Te WhakangāwariHe rerekē ki ngā fiusi e hiahia ana kia whakakapia i muri i te pupuhitanga, he ngāwari noa te tautuhi anō i ngā whati ara iahiko Mcb, he mea ngāwari ake te whakamahi.
3. Hoahoa KiatoHe iti ake, he whāiti ake hoki ngā whati ara iahiko MCB i ngā taputapu tiaki ara iahiko tuku iho, ā, ka taea te whakamahi pai ake i te wāhi i roto i ngā panera hiko.
4. Whai hua te utuAhakoa he nui ake te haumitanga tuatahi i ngā fiusi, ko ngā penapena roa mai i te iti o te kino o ngā taputapu me te ngāwari o te tautuhi anō ka waiho ngā kaiwawao ara iahiko Mcb hei whiringa utu-pai.
Te Tāutanga me te Tiaki
Me mahi tonu te tāutanga o ngā kaiwawao hiko e te tohunga hiko whai tohu kia tutuki ai ngā ture hiko ā-rohe me ngā paerewa haumaru. E taunakihia ana hoki kia tirohia ngā tiaki auau kia tika ai te mahi a ngā kaiwawao hiko, kia kitea ai hoki ngā raruraru pea i mua i te kino rawa atu.
He aha te rerekētanga i waenga i ngā kaiwawao MCB me ngā kaiwawao MCCB?
Ngā MCB: E whakamahia whānuitia ana i roto i ngā tono arumoni me ngā tono ahumahi iti-ngaohiko, ko te tikanga he 120V, 240V, 480Y VAC rānei, tae atu ki te 1000 VDC. Ngā MCCB: Ka taea te whakamahi mō ngā tono ngaohiko iti me te ngaohiko teitei, me ngā whakatauranga tae atu ki te 600V, 690V rānei, ā, ko ētahi tauira he whakatauranga mō ngā ngaohiko teitei ake.
Hei whakarāpopototanga
He mea nui ngā whati hiko MCB i roto i ngā pūnaha hiko hou, e whakarato ana i te haumaru, te whai huatanga, me te whai huatanga. Mā te mārama ki ō rātou mātāpono mahi, ngā momo, me ngā painga ka āwhina i ngā kaipupuri whare me ngā pakihi ki te whakatau whai whakaaro mō ā rātou hiahia tiaki hiko. I te whanaketanga tonu o te hangarau, ka noho tonu ngā whati hiko MCB hei poutokomanawa mō te haumaru hiko, me te whakarite kia tiakina ō tātou kāinga me ngā wāhi mahi mai i ngā tūponotanga hiko.
