I te wiki kua taha ake nei, i tae mai he tono āwhina mai i tētahi kiritaki: kua oti noa i tana wheketere tukatuka iti te whakahou i te tohatoha hiko, engari he maha ngā wā ka motu te raina whakaputa i roto i ngā rā e toru noa iho i muri i te tīmatanga. Tae atu ki tētahi motuka i wera ōna wāhanga matua nā te mea kāore i taea te tapahi i te iahiko poto i te wā tika, ā, tata ki te 10,000 yuan te mate tika. I muri i te rangahau, i kitea ko te raruraru kei roto i te kōwhiringa o ngā kaiwawao hiko tino taketake - hei penapena utu, i whakakapia e rātou ngā Kaiwawao Hiko Molded Case (MCCB) katoa i tika kia whakamahia i runga i ngā raina tohatoha hiko matua ki ngā Kaiwawao Hiko Iti (MCB) iti ake, iti ake te utu. I te āhua nei he penapena moni iti, engari i whakatōkia he tūponotanga nui huna.
Ina hoki, he mea noa ēnei āhuatanga i roto i ngā horopaki tohatoha hiko ā-pākihi me ā-iwi. Hei "kaitiaki haumaru" e whakamahia whānuitia ana i roto i ngā pūnaha tohatoha hiko, he rite te āhua me te mahi taupatupatu a MAC me MCCB, engari he rerekētanga nui kei waenganui i a rāua. He maha ngā kaihoko pakihi me ngā tohunga hiko e taka ana ki ngā whakaaro hē mō te whiriwhiri nā te kore mārama ki ō rāua āhuatanga, ā, i te mutunga ka arahi pea tēnei ki te kino o ngā taputapu, ki ngā aituā haumaru, ki te maumau moni rānei.
Mai i tēnei take tūturu, mā mātou koe e āwhina i te tuatahiwhakamāramahia ngā rerekētanga matua i waenga i te MCB me te MCCB, kātahi ka wetewetehia tika ngā whakaaro hē e toru e kitea whānuitia ana i roto i te kōwhiringa, ka whakataurite i aua whakaaro ki ngā tikanga kōwhiringa tika me ngā kaupapa tautoko hinonga hei āwhina i a koe ki te karo i ngā mahanga katoa me te whiriwhiri i te kaiwawao ara iahiko tika mō tō horopaki, he mea utu iti, he mea whakamarie hoki.
I. Tuatahi, Kia Mārama: He aha te Rerekētanga i waenganui i te MCB me te MCCB? (He Kaupapa hei Ārai i ngā Whakaaro Hē)
Hei karo i ngā whakaaro hē mō te kōwhiringa, ko te taahiraa tuatahi ko te whakamārama kāore a MCB me MCCB i roto i te whanaungatanga "whakakapinga rahi", engari he whanaungatanga "whakaurunga horopaki". He māmā noa iho, he rerekē te tūnga matua o ngā mea e rua, ā, he tino rerekē ngā horopaki e tika ana. Ka whakamahia e mātou te reo rongonui me ngā tawhā kua whakangawaritia hei āwhina i a koe ki te wehewehe wawe i a rāua.
Ngā Rerekētanga Tūnga Matua
- MCB"Kaitiaki Mutunga", e arotahi ana ki te whakaitiiti me te tiakitanga taketake, e kawenga ana mō te haumaru o ngā ara iahiko peka i te mutunga o te tohatoha hiko (pērā i te rama, ngā rorohiko, me ngā ara iahiko motuka iti);
- MCCB"Kaitiaki Raina Matua", e arotahi ana ki te kaha nui me te tiaki tino tika, e kawenga ana mō te haumaru o ngā raina tohatoha hiko matua me ngā taputapu mana-nui (pērā i ngā raina whakaputa wheketere, ngā papu nui, me ngā ara iahiko matua o ngā pouaka tohatoha).
Whakataurite Tawhā Matua
| Tūemi Whakataurite | Pūwhakapakari Arahiko Iti (MCB) | Kaiwhakamutu Arahiko Kua Whakarewahia (MCCB) |
| Iahiko Whakatauranga | 6A-63A (Utaina Iti) | 10A-800A (Utaina Nui) |
| Te kaha pakaru | 6kA-10kA (Iti, mō ngā Ara Poto Iti) | 15kA-100kA (Teitei, mō ngā Ara Poto Nui) |
| Mahi Tiaki | Te parenga taketake mō te taumaha me te ara iahiko poto (māmā, whai hua hoki) | Ka taea te tāpiri i ngā mahi maha pēnei i te whakaroa roa o te taumaha, te whakaroa poto-ara iahiko, me te tiaki i te ngaohiko iti (tika me te whānui) |
| Ngā horopaki e tika ana | Ngā ara iahiko peka mutunga ā-iwi/ā-umanga (rama, motuka iti) | Ngā ara iahiko matua ahumahi, ngā taputapu mana-teitei (ngā raina whakaputa, ngā papu nui) |
II. Te Wetewete Matua: 3 Ngā Whakaaro Hē Noa i te Kōwhiringa, 90% o te Tangata Kua Takahia e rātou
Ahakoa ngā rau o ngā kēhi kua tūtaki mātou, ko ngā hē i te whiriwhiri i te MCB me te MCCB e aro nui ana ki ēnei āhuatanga e toru. Ina koa mō ngā tīmatanga, he mea nui kia aro nui ki ēnei āhuatanga kia kore ai e whakahokia ngā hē a te kiritaki i te tīmatanga.
Whakaaro Hē 1Arotahi ki te Utu/Rahi anake, me te Whakakapi Matapōkere (Ko te mea tino noa, ko te mea tino mōrearea hoki)
✅Mahi HēPērā i te kiritaki i te tīmatanga, e whakaaro ana he iti, he iti hoki ngā MCB, nō reira ka whakakapia te MCCB ki te MCB; ka whai rānei i te "pūmautanga" ka whakamahi i te MCCB mō ngā āhuatanga katoa ahakoa te rahi, ka hua ake he "rahi rawa".
Hei tauira: I te ara iahiko matua o tētahi wheketere (kei runga ake i te 100A te auhiko whakatauranga), mā te whakakapi i te MCCB ki te MCB ka kore e ranea te kaha pakaru. Ina puta he ara iahiko poto, kāore e taea te motu i te auhiko hapa i te wā tika, ka tino tūpono ka pau ngā taputapu me te ahi; i te ara iahiko rama mutunga (kei raro iho i te 10A te auhiko whakatauranga), he nui ake te utu o te whakamahi i te MCCB, engari kāore hoki e taea te uru ki roto i te pouaka tohatoha mutunga nā te rahi, he maumau noa iho.
✅Huarahi TikaKo te uho o te kōwhiringa ko te taurite i te kawenga, ehara i te utu/rahi. Tuatahi tatauhia te iahiko whakatauranga me te iahiko ara-poto o te ara iahiko, kātahi ka tīpakohia e rite ana:
- Ngā ara iahiko peka mutunga (iahiko ≤ 63A, iahiko ara iahiko poto ≤ 10kA): Whakaritea te MCB (he utu whai hua, he rawaka hoki);
- Ngā ara iahiko matua me ngā taputapu mana-teitei (auau ＞ 63A, au ara iahiko poto ＞ 10kA): Me tīpako te MCCB (haumaru tuatahi, kāore e taea te tiaki).
Whakaaro Hē 2: Whakapoauau i ngā Mahi Tiaki, ka Whakaaro "I te mea ka taea e ia te tiaki, he nui noa iho"
✅Mahi HēHe tokomaha te hunga e whakaaro ana he ārai-taikaha, he ārai-poto hoki te MCB me te MCCB, nō reira ka taea e rātou te whiriwhiri noa i tētahi, me te kore e aro ki ngā rerekētanga o te tika me ngā mahi tiaki, ā, ka mutu, ka kore e ranea te tiaki.
Hei tauira: Ko te ara iahiko motuka mana-teitei o te raina whakaputa me "tiakitanga whakaroa roa" (ka tere te uta o te motuka ina tīmata, ā, me whakaroa te whakaroa hei karo i te whakaweto teka), engari ka tīpakohia he MCB me te "tiakitanga tere" anake. Nō reira, ka whakaweto te MCB i te tīmatanga o te motuka, ka maha ngā whakaweto o te raina whakaputa, ā, ka pā ki te whakaputa; i te ritenga kē, ko te ara iahiko rama kāinga me tiaki taketake anake, engari ka tīpakohia he MCCB me ngā mahi tāpiri maha, ehara i te mea he utu nui engari he ngāwari hoki ki te whakaweto teka, ka pā ki te whakamahinga hiko noa.
✅Huarahi TikaKōwhiria ngā hua kia rite ki ngā "hiahia tiaki", ā, he mea whai hua te taurite tika:
- Ko te tiakitanga taketake anake e hiahiatia ana (ngā taputapu iti: rama, rorohiko, motuka iti): Tīpakohia te MCB (e ranea ana hei whakatutuki i ngā hiahia);
- E hiahiatia ana te tiakitanga tino tika me te maha-ahu (ngā motuka mana-nui, ngā raina matua): Tīpakohia te MCCB (ka taea te tāpiri i te taumaha rawa, te whakaroa roa me te tiakitanga ngaohiko iti hei karo i te rahunga tiaki/tiakitanga rūpahu).
Whakaaro hē 3Kaua e aro ki te taiao tirohanga, engari whakamahia te kōwhiringa "Kotahi te rahi mō te katoa".
✅Mahi HēI te wā e whiriwhiri ana, kāore e whakaarohia te taiao o te wāhi (te pāmahana, te haumākū, te puehu) me ngā āhuatanga o te kawenga (AC/DC, te tīmatanga auau), ā, ka whiriwhiria te momo whati hiko kotahi mō ngā hiko katoa, ka hua ake he poto te ora mahi me te maha o ngā pakaru o te whati hiko.
Hei tauira: I roto i tētahi awheawhe matū pāmahana teitei, haumākū, me te puehu, ka whakamahia ngā MCB noa hei utu mō te MCCB me ngā taumata tiaki teitei. Nō reira, ka maha ngā wā ka pakaru te MCB nā te haumākū me te pāmahana o te taiao; i roto i te ara iahiko pito DC o tētahi teihana hiko photovoltaic, ka whakamahia ngā MCB AC noa, ka kore e taea te tineia ngā pewa DC, ka kore e pai te whakapā atu, ka pakaru hoki ngā taputapu.
✅Huarahi TikaKōwhiria i runga i te "tirohanga + kawenga" mō te roa:
- Ngā āhuatanga kino (pāmahana teitei, haumākū, puehu): Whakaritea te MCCB me ngā taumata tiaki teitei (IP54 me runga ake);
- Ngā whakaaturanga DC (photovoltaics, rokiroki pūngao): Tīpakohia te MCB/MCCB motuhake ki te DC (kāore e taea te whakamahi i ngā tauira AC);
- Ngā ara iahiko tīmatanga pinepine o te motuka: Tīpakohia te MCCB me te tiakitanga mō te whakaroa roa mō te taumaha rawa;
- Ngā wāhi ma (ngā tari, ngā taiwhanga, ngā mahi ā-ture): Kōwhiria he MCB noa (he utu iti, he pai hoki te urutau).
III. Aratohu Whaihua: 4 Ngā Hipanga hei Whakaoti i te Kōwhiringa me te Kore e Hē (Ka Taea e te Tīmatanga te Ako)
I te taha o ngā whakaaro hē o runga ake nei, ka whakarāpopotohia e mātou ētahi mahi whiriwhiri māmā e whā, e taea ana hoki. Ahakoa he wāhi ahumahi, he wāhi ā-iwi rānei, mā te whai i ēnei mahi ka taea e koe te whiriwhiri i te kaiwawao hiko tika me te kore e tono āwhina i ētahi atu.
1. Tātaihia ngā Tawhā: Tuatahi, tātaihia mārama te iahiko whakatauranga me te tihi iahiko poto o te ara iahiko, whakatauhia te paerewa iti rawa o te whakatakotoranga pakaru ara iahiko e hiahiatia ana, ā, tuatahi whakatauhia mēnā me whakamahi te MCB, te MCCB rānei;
2. Whakamāramahia ngā Whakaritenga: Kimihia ngā mahi tiaki e hiahiatia ana e te ara iahiko — mēnā ko te tiakitanga taketake anake e hiahiatia ana, ko ngā mahi tino tika me ngā mahi tāpiri maha rānei e hiahiatia ana;
3. Whakarerekē ki te Wāhi: Whakatauhia te momo hua me te taumata tiaki e ai ki te taiao wāhi (pāmahana, haumākū) me ngā āhuatanga kawenga (AC/DC, tīmatanga auau);
4. Whakatauritehia te Utu me te Mahi: Kōwhiria te MCB mō ngā ara iahiko mutunga (he penapena utu), me te MCCB mō ngā raina matua/ara iahiko mana-nui (haumaru tuatahi). Kaua e whaia noatia te "utu nui" kaua hoki e hiahia ki te "iti".
IV. Tautoko Pakihi: Kōwhiria te Kaiwhatu Ara Tika me te kore he Mātauranga Ngaio
He tokomaha pea ngā hoa e kī ana: "Kāore au i te mārama ki ngā tawhā, he uaua rawa te tirohanga, ā, kei te mataku tonu ahau kei whiriwhiria e au te mea hē. Me aha ahau?" Kaua e manukanuka. Hei kaiwhakarato ratonga ngaio i roto i te mara taputapu tohatoha hiko, ka whakaratohia e mātou he ratonga tautoko katoa hei āwhina i a koe ki te karo i ngā mahanga katoa o te kōwhiringa, me te penapena i te wā me te kaha.
1. Kōrerorero Ngaio Takitahi: Ka tohua ngā miihini hangarau matua ki te hono atu ki a koe, ki te mārama hohonu ki tō tirohanga, ki ngā tawhā kawenga me te tahua, hei āwhina i a koe ki te whakatau i ngā whakaaro kōwhiringa, ā, kāore koe e hiahia ki te tirotiro i ngā tawhā me te wehewehe i ngā rerekētanga e koe anake;
2. Tātaitanga Tawhā Koreutu: Āwhina i a koe ki te tātai tika i te iahiko porowhita me te iahiko porowhita-poto, tūtohu i ngā tauira MCB/MCCB e tika ana, whakamārama i ngā tawhā whakatauranga me ngā mahi tiaki, me te whakarite kia kore he peka i roto i te kōwhiringa;
3. Taunakitanga Whakaritenga mō te Horopaki: Mō ngā āhuatanga motuhake pēnei i te ahumahi matū, te photovoltaics, me te tīmatanga o te motuka, tūtohu hua motuhake, āwhina ki te whakaoti i te urutau o te taumata tiaki me ngā mahi tāpiri, me te whakataurite i te haumaru me te pakari;
4. Tautoko Whai muri i te Hoko: Whakarato aratohu tāutanga me ngā ratonga whakatūnga tawhā i muri i te kōwhiringa. Mena he raruraru e pā ana ki te kōwhiringa i muri mai, whakaratohia he otinga i te wā tika hei whakarite i te mahi pumau o te pūnaha tohatoha hiko.
Whakatau: Ko te whiriwhiri i te Pūwhakawhiti Ara Tika he penapena utu, he whakarite hoki i te haumaru
Ina hoki, ehara i te mea uaua te whiriwhiri i te MCB me te MCCB. Ko te kaupapa matua ko "kāore he whakakapinga matapo, kāore he kore aro ki ngā rerekētanga, ā, kāore he wehenga mai i ngā tirohanga". Ko te take o te kiritaki i te tīmatanga te akoranga tino pono - te penapena rau yuan i roto i ngā utu whiriwhiri, engari te ngaro tata ki te 10,000 yuan i roto i ngā utu taputapu, kāore e tika ana te hua.
Ahakoa he wheketere tukatuka iti koe, he umanga nui rānei, he mahi whakahou tohatoha hiko ā-iwi rānei, ki te mea kei te raru koe i te whiriwhiri i te MCB me te MCCB, whakapā mai ki a mātou.NGĀ TANGATAKa whakamahia e mātou ngā hangarau ngaio me ngā wheako whai rawa hei āwhina i a koe ki te whiriwhiri i te kaiwawao ara iahiko tika, e kore e ārai noa i ngā whakaaro hē o te kōwhiringa me te whakaiti i ngā utu, engari ka hanga hoki i tētahi raina haumaru pakari mō te tohatoha hiko, e āhei ai te pūnaha tohatoha hiko ki te mahi pūmau me te iti ake o ngā raruraru me ngā painga maha atu.
