Te māramatangaMCCBmeMCBNgā Wāhanga Taketake o ngā Pūnaha Hiko
I roto i te ao hangarau hiko me te tohatoha hiko, he maha ngā wā ka tūtaki tātou ki ngā kupu "molded case circuit breaker (MCCB)" me te "miniature circuit breaker (MCB)". He mea nui te mahi a ngā taputapu e rua ki te tiaki i ngā ara iahiko mai i ngā taumahatanga me ngā ara iahiko poto, engari he rerekē ngā whakamahinga me ngā hoahoa. Ka ruku hohonu tēnei tuhinga ki ngā āhuatanga, ngā mahi, me ngā tono o ngā molded case circuit breaker (MCCB) me ngā miniature circuit breaker (MCB), ā, ka whakamāramahia tō rātou hiranga ki te whakarite i te haumaru me te whai huatanga o te hiko.
He aha te MCB?
He taputapu iti te kaiwawao hiko iti (MCB) i hangaia hei tiaki i ngā hiko mai i ngā taumahatanga me ngā poto o te hiko. He mea whakamahi ngā MCB mō ngā whare noho me ngā mahi arumoni me ngā reiti iahiko iti, mai i te 0.5A ki te 125A. Ina kitea he hapa, ka momotu aunoa i te hiko, ā, ka ārai i te kino o ngā taputapu me te whakaiti i te tūponotanga o te ahi.
Ka mahi ngā MCB i runga i ngā mātāpono whakapōrearea wera me te aukume. Ka whakamahia te tikanga whakapōrearea wera hei whakautu ki ngā āhuatanga taumaha rawa, ko te tikanga whakapōrearea aukume hei whakautu ki ngā āhuatanga ara iahiko poto. Mā tēnei mahi takirua ka taea e ngā whakapōrearea hiko iti te whakarato i te tiaki pono mō te whānuitanga o ngā pūnaha hiko. Hei tāpiri, he ngāwari te tautuhi anō i ngā whakapōrearea hiko iti i muri i te whakapōrearea, he mea ngāwari ki te whakamahi, ā, ka taea te whakahaere pai i roto i te whakamahinga o ia rā.
He aha te MCCB?
He taputapu pakari ake ngā Pouaka Ara Iahiko Whakapoke (MCCB) e whakatauria ana mai i te 100A ki te 2500A. He maha ngā whakamahinga o ngā MCCB i ngā wāhi ahumahi me ngā wāhi arumoni kei reira ngā kawenga hiko nui. He rite ki ngā MCB, ka tiaki ngā MCCB i ngā taumahatanga me ngā ara iahiko poto, engari he āhuatanga matatau ake, tae atu ki ngā tautuhinga pakaru ka taea te whakarite me te kaha ki te whakahaere i ngā iahiko hapa teitei ake.
Ko ngā whati hiko whakapūkara (MCCB) he hanganga pouaka whakapūkara e pupuri ana i ngā wāhanga o roto, e whakarato ana i te pakari me te tiaki mai i ngā āhuatanga taiao. Kei roto hoki i ēnei he āhuatanga tāpiri pēnei i te tiaki i te hapa whenua me ngā āheinga whakawhitiwhiti kōrero, e āhei ai te whakauru atu ki roto i ngā pūnaha hiko uaua ake. Nā tēnei ka pai ngā MCCB mō ngā tono i roto i ngā whare hanga, ngā pokapū raraunga, me ngā whare arumoni nui.
Ngā Rerekētanga Matua i waenga i te MCB me te MCCB
1. Iahiko whakatauranga: Ko te rerekētanga nui i waenga i te Miniature Circuit Breaker (MCB) me te Molded Case Circuit Breaker (MCCB) ko tōna iahiko whakatauranga. He pai ngā MCB mō ngā tono iahiko iti (tae atu ki te 125A), ko ngā MCCB ia he pai mō ngā tono iahiko teitei (100A ki te 2500A).
2. Whakamahinga: Ko te nuinga o ngā MCB e whakamahia ana i roto 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.
3. Tikanga Whakatō: He pumau ngā tautuhinga tō o ngā MCB, engari he taea te whakarite i ngā tautuhinga tō o ngā MCCB, kia taea ai te whakarite kia rite ki ngā whakaritenga kawenga motuhake.
4. Rahi me te Hoahoa: He iti ake, he whāiti ake hoki ngā whati hiko iti (MCB), he mea tino pai mō ngā taiao he iti te wāhi. He rerekē, he nui ake, he pakari ake, ā, he mea hanga ngā whati hiko kua whakakikoruatia (MCCB) hei whakahaere i ngā kawenga hiko teitei ake.
5. Utu: I te nuinga o te wā, he iti ake te utu o ngā MCB mō ngā tono iti-mana, engari he nui ake te utu o ngā MCCB nā ō rātou āhuatanga matatau me ngā whakatauranga teitei ake.
Hei whakamutunga
Hei whakarāpopototanga, he wāhanga nui ngā MCCB me ngā MCB i roto i ngā pūnaha hiko, ā, he rerekē ngā mahi a ia taputapu i runga i ngā whakaritenga o te tono. He mea nui te mārama ki ngā rerekētanga i waenga i ēnei taputapu e rua hei whiriwhiri i te otinga tiaki ara iahiko e tika ana. Ahakoa mō te whakamahinga kāinga, mō te whakamahinga ahumahi rānei, he mea nui te whakarite kia whakamahia tika ngā MCCB me ngā MCB hei pupuri i te haumaru hiko, te whai huatanga, me te pono. I te whanaketanga tonu o te hangarau, ka noho tonu te mahi a ēnei kaiwawao ara iahiko hei wāhanga nui o te whakahaere haumaru o ngā pūnaha hiko huri noa i te ao.
