Ngā mahi me ngā rerekētanga i waenga i te MCB me te MCCB

Te māramatangaMCCBmeMCBNgā Rerekētanga Matua me ngā Whakamahinga

I roto i ngā mara o te hangarau hiko me te tiaki ara iahiko, e rua ngā kupu e whakamahia pinepinetia ana: MCB (miniature circuit breaker) me MCCB (molded case circuit breaker). E mahi ana ngā taputapu e rua i te mahi nui o te tiaki i ngā ara iahiko mai i ngā taumahatanga me ngā ara iahiko poto, engari he rerekē rawa te hoahoa, te tono, me ngā āheinga whakahaere. Ko te whāinga o tēnei tuhinga he whakamārama i ngā rerekētanga i waenga i ngā MCB me ngā MCCB, hei āwhina i a koe ki te mārama ki te wā me te take e whakamahia ai ia mea.

He aha te MCB?

He taputapu iti te kaiwawao hiko iti (MCB) e whakamahia ana hei tiaki i ngā hiko mai i ngā taumahatanga me ngā poto o te hiko. He mea whakamahi noa ngā MCB i ngā whare noho me ngā whare pakihi me ngā reiti iahiko iti, mai i te 0.5A ki te 125A. Ina nui ake te iahiko i tētahi taumata kua whakaritea, ka motu aunoa te MCB, ka ārai i te kino pea ki te hiko me ngā taputapu hono.

He tere te urupare a ngā MCB, he mea nui tēnei hei whakaiti i ngā kino i puta mai i ngā hapa. Ka taea hoki te tautuhi anō, arā, ina oti te hapa te whakakore, ka taea te tautuhi anō i te MCB me te kore e whakakapi. Nā tēnei āhuatanga ka rongonui ngā MCB hei whiringa mō te tiaki i ngā ara iahiko rama, ngā putanga hiko, me ngā taputapu iti.

He aha te MCCB?

Ko ngā MCCB ia, he pakari ake, ā, he mea hanga mō ngā tono hiko teitei ake, mai i te 100A ki te 2500A. He mea whakamahi noa ngā MCCB i ngā taiao ahumahi me ngā taiao arumoni me ngā kawenga hiko taumaha. Ka whakaratohia e rātou he tiaki taumaha, he tiaki poto, me te tiaki whenua-hapa, kia pai ai mō te whānuitanga o ngā tono.

Kei ngā whati ara iahiko pouaka whakarewa (MCCB) ngā tautuhinga wehenga ka taea te whakarite, e āhei ai ngā kaiwhakamahi ki te whakarite i te taumata tiaki ki ngā whakaritenga motuhake o te pūnaha hiko. He tino whai hua tēnei āhuatanga i roto i ngā taiao ahumahi e rerekē ai ngā tono o nāianei o ngā taputapu. He maha ngā wā ka whakaurua e ngā MCCB ngā āhuatanga matatau pērā i te aroturuki mamao me ngā whakawhitiwhiti kōrero, e whakarei ake ana i ā rātou mahi i roto i ngā pūnaha hiko uaua.

Ngā rerekētanga matua i waenga i te MCB me te MCCB

1. Whakatauranga Au**: Ko te rerekētanga nui i waenga i te MCB me te MCCB ko tō rāua whakatauranga au. He pai te MCB mō ngā tono au iti (tae atu ki te 125A), ko te MCCB ia he pai mō ngā tono au teitei ake (100A ki te 2500A).

2. Te Āheinga ki te Whakarite: He pumau ngā tautuhinga haerenga o ngā MCB, engari he ngāwari ake te tiaki i te ara iahiko mā te MCCB.

3. Whakamahinga: Ko ngā MCB e whakamahia ana i ngā whare noho me ngā mahi arumoni māmā, ko ngā MCCB ia he mea hanga mō ngā mahi ahumahi me ngā mahi arumoni taumaha, e nui ake ai ngā kawenga me ngā pūnaha uaua ake.

4. Rahi me te Hoahoa: Ko ngā whati hiko iti (MCB) he iti ake, he kiato ake i ngā whati hiko pouaka whakarewa (MCCB), ā, he māmā ake te tāuta ki ngā wāhi iti. He nui ake ngā whati hiko pouaka whakarewa (MCCB), he nui ake te wāhi e hiahiatia ana, ā, he maha ngā wā ka tāutahia ki ngā huihuinga taputapu whakawhiti.

5. Utu: Ko ngā pakaru hiko iti (MCB) he iti ake te utu i ngā pakaru hiko tauira (MCCB), ā, he otinga whai hua mō ngā tono iti ake. Heoi, nā te nui haere o ā rātou mahi me ā rātou mahi, he haumitanga pai ki ngā taiao nui ake, uaua ake.

Hei whakarāpopototanga

Hei whakarāpopototanga, he mea nui ngā parenga hiko iti (MCB) me ngā parenga hiko pouaka whakarewa (MCCB) ki te tiaki i te hiko, engari he rerekē rawa ā rāua whakamahinga me ō rāua āheinga. He mea nui te mārama ki ēnei rerekētanga hei whiriwhiri i te taputapu tika mō ō hiahia. Ahakoa kei te tiaki koe i tētahi hiko kāinga iti, i tētahi pūnaha ahumahi nui rānei, mā te whiriwhiri i te parenga hiko tika ka whakarite i te haumaru, te pono, me te whai huatanga o ō taputapu hiko. Me kōrero tonu ki tētahi tohunga hiko, ki tētahi miihini hiko rānei hei whakatau i te otinga pai mō tō āhuatanga.
