Te mārama ki ngā kaupapa matua o te DC MCCB (Moulded Case Circuit Breaker)
Mō ngā pūnaha hiko, he mea nui te haumaru. Koia te take me whakarato he parenga pono mō te taumaha me te ara iahiko poto. I roto i ngā pūnaha iahiko tika (DC), ko te wāhanga matua hei whakarite i te haumaru ko te DC Molded Case Circuit Breaker (MCCB). I roto i tēnei tuhinga, ka rukuhia e mātou ngā kaupapa matua o ngā DC MCCB me te take he mea nui rātou i roto i ngā tatūnga hiko.
Tuatahi, me mārama tātou he aha te mea he whati hiko whakapokepoke. Ko te MCCB he taputapu tiaki hiko e momotu aunoa ana i te hiko ina puta he taumaha rawa, he poto rānei te hiko. I roto i ngā pūnaha DC, he mea nui te mahi a ngā MCCB ki te ārai i ngā ahi hiko me ngā kino o ngā taputapu mā te whakakore tere i te rere o te hiko.
He rerekētanga matua ētahi i waenga i ngā kaiwawao hiko hiko DC me ngā kaiwawao hiko AC. Me whai MCCB motuhake ngā pūnaha DC hei whakahaere i ngā āhuatanga ahurei o ngā pūhiko hiko DC, tae atu ki ngā taumata ngaohiko teitei ake me ngā whakaritenga aukati iahiko tino kaha ake. Nō reira, kua hangaia ngā kaiwawao hiko DC me ngā mahi motuhake hei whakarite kia taea ai e rātou te tiaki pai i ngā pūnaha hiko DC.
Ko tētahi āhuatanga nui o tētahi kaiwawao hiko hiko DC i hangaia ki te tauira ko tōna ngaohiko whakatauranga. Kāore i rite ki ngā MCCB AC e whakataurangahia ana i ngā ngaohiko iti iho, kua hangaia ngā MCCB DC hei whakahaere i ngā taumata ngaohiko teitei ake. He mea nui tēnei kia taea ai e ngā kaiwawao hiko te whakakore haumaru i te rere o te hiko i roto i ngā pūnaha DC ngaohiko teitei me te kore e pupuhi, e kino rānei i ngā taputapu.
Ko tētahi atu āhuatanga nui o ngā kaiwawao hiko hiko DC kua whakakikoruatia ko tōna kaha ki te pakaru. I roto i ngā pūnaha DC, he mea nui te kaha o te kaiwawao hiko ki te whakakore haumaru i te rere o te hiko i te wā e puta ai he hapa. He nui te kaha ki te pakaru o ngā kaiwawao hiko DC kua whakakikoruatia, ā, ka taea te whakahaere pai i ngā āhuatanga morearea ka puta pea i roto i ngā hiko DC.
Hei tāpiritanga, he maha ngā wā ka hangaia ngā whati hiko DC kua whakakikoruatia me ngā āhuatanga tāpiri pēnei i te aro ki te polarity me te tiaki hononga whakamuri. Mā ēnei āhuatanga ka taea e ngā whati hiko te kite tika me te urupare ki ngā hapa i roto i ngā pūnaha DC, ka whakapai ake i te haumaru me te pono.
I te wā e whiriwhiri ana i tētahi whati ara iahiko DC i hangaia mō tētahi tono motuhake, he mea nui kia whakaarohia ngā āhuatanga pēnei i te whakatauranga ngaohiko, te whakatauranga iahiko, me ngā whakaritenga motuhake o te pūnaha hiko. Mā te mahi tahi me tētahi kaiwhakarato mātau, me tētahi miihini rānei, ka āwhina i te whakarite kia tika te mahi.DC MCCBkua tīpakohia mō te tono, e whakarato ana i te tiakitanga pono me te rangimarie o te hinengaro.
Hei whakarāpopototanga,Ngā whati ara iahiko pouaka whakarewa DCHe mea nui ngā MCCB DC hei whakarite i te haumaru me te pono o ngā pūnaha hiko DC. Nā tōna hoahoa me te mahi motuhake, he mea nui ngā MCCB DC mō te tiaki i te taumaha me te ara iahiko poto i roto i ngā tono hiko DC ngaohiko teitei. Mā te mārama ki ngā kaupapa matua o ngā kaiwawao hiko kua whakakikoruatia ki te pouaka DC, ka taea e ngā tohunga hiko te whakatau whai whakaaro i te wā e whiriwhiri ana me te tāuta i ēnei wāhanga nui. I te nuinga, ko te haumi ki tētahi kaiwawao hiko kounga teitei he taahiraa nui hei whakarite i te haumaru o tō pūnaha hiko DC.
E hiahia ana tō pūnaha hiko ki ngā pūwhakaweto hiko DC kounga teitei, pono hoki? Tena koa whakapā mai ki a mātou i tēnei rā ki te ako atu mō ā mātou hua. Kia haumaru, kia harikoa hoki ō waea!
