He mea nui te whiriwhiri i tētahi kawenga rūpahu mō te huinga whakaputa hiko tīhiera o te pokapū raraunga, nā te mea ka pā tika ki te pono o te pūnaha hiko tārua. Kei raro nei, ka whakaratohia e au he aratohu whānui e kapi ana i ngā mātāpono matua, ngā tawhā matua, ngā momo kawenga, ngā mahi whiriwhiri, me ngā mahi pai.
1. Ngā Mātāpono Kōwhiri Matua
Ko te kaupapa matua o te kawenga teka he whakatauira i te kawenga tūturu hei whakamātautau whānui me te whakamana i te huinga whakaputa hiko tīhiera, kia taea ai e ia te kawe tonu i te kawenga nui katoa mēnā ka pakaru te hiko matua. Ko ngā whāinga motuhake ko:
- Te Tahu i ngā Putunga Waro: Mā te oma i te kawenga iti, i te kore kawenga rānei, ka puta he āhuatanga "pūpū mākū" i roto i ngā miihini tīhiera (ka kohia te wahie kāore i tahuna me te waro ki roto i te pūnaha whakaputanga hau). Ka taea e te kawenga rūpahu te whakanui ake i te pāmahana me te pēhanga o te miihini, ka tahuna katoatia ēnei putunga.
- Manatoko Mahi: Te whakamātautau mēnā kei roto i ngā rohe e whakaaetia ana te mahi hiko o te huinga whakaputa hiko—pērā i te ngaohiko putanga, te pumau auau, te whakapōturitanga o te ngaru (THD), me te whakahaere ngaohiko.
- Whakamātautau Āheinga Utaina: Te manatoko ka taea e te huinga whakaputa hiko te mahi pumau i te mana kua whakatauria, me te aromatawai i tōna kaha ki te aro atu ki te tono me te whakakorenga ohorere o te kawenga.
- Whakamātautau Whakaurunga Pūnaha: Te whakahaere tahi i te whakaurunga me te ATS (Aunoa Whakawhiti Whakawhiti), ngā pūnaha whakarara, me ngā pūnaha whakahaere hei whakarite kia mahi tahi te pūnaha katoa.
2. Ngā Tawhā Matua me ngā Whakaaroaro
I mua i te kōwhiri i tētahi kawenga teka, me whakamārama ngā tawhā e whai ake nei mō te huinga whakaputa me ngā whakaritenga whakamātautau:
- Mana Whakatauria (kW/kVA): Me nui ake, me ōrite rānei te kaha katoa o te kawenga rūpahu ki te kaha katoa kua whakatauria o te huinga whakaputa hiko. E taunakihia ana kia tīpakohia te 110%-125% o te kaha whakatauria o te huinga hei whakamana i te whakamātautau kaha taumaha.
- Ngaohiko me te Wāhanga: Me ōrite te ngaohiko putanga o te pūkaha hiko (hei tauira, 400V/230V) me te wāhanga (waea-toru-wāhanga-whā).
- Auautanga (Hz): 50Hz, 60Hz rānei.
- Tikanga Hononga: Me pēhea te hono atu ki te putanga whakaputa hiko? Ko te tikanga kei raro iho i te ATS, mā roto rānei i tētahi kāpata atanga whakamātautau motuhake.
- Tikanga Whakamatao:
- Whakamatao Hau: He pai mō te mana iti ki te mana waenga (i raro iho i te 1000kW te nuinga), he iti ake te utu, engari he haruru, ā, me tuku tika te hau wera mai i te rūma taputapu.
- Whakamatao Wai: He pai mō te mana waenga ki te mana teitei, he marino ake, he pai ake te pai o te whakamatao, engari me whai pūnaha wai whakamatao tautoko (pou whakamatao, pouaka whakamatao maroke rānei), ka nui ake te haumitanga tuatahi.
- Taumata Whakahaere me te Aunoatanga:
- Mana Taketake: Te uta/te tango ā-ringa i ngā taahiraa.
- Mana Whakahaere Maamaa: Ngā pihi uta aunoa ka taea te whakarite (uta pikinga, uta hikoi), te aroturuki me te tuhi i ngā tawhā pēnei i te ngaohiko, te iahiko, te hiko, te auau, te pēhanga hinu, te pāmahana wai, me te whakaputa pūrongo whakamātautau. He mea nui tēnei mō te tutuki i ngā whakaritenga me te arotake a te pokapū raraunga.
3. Ngā Momo Matua o ngā Utaina Hē
1. Kawenga Ātete (Kawenga Kaha Pūmau P)
- Mātāpono: Ka huri i te pūngao hiko hei wera, ka whakamararatia e ngā pā hau, e te wai rānei hei whakamatao.
- Ngā Painga: He hanganga māmā, he utu iti, he ngāwari te whakahaere, e whakarato ana i te mana hohe parakore.
- Ngā Huakore: Ka taea anake te whakamātautau i te mana hohe (kW), kāore e taea te whakamātautau i te kaha whakahaere mana tauhohe (kvar) o te whakaputa hiko.
- Horopaki Taupānga: E whakamahia ana mō te whakamātautau i te wāhanga miihini (te mura, te pāmahana, te pēhanga), engari kāore anō kia oti te whakamātautau.
2. Kawenga Tauhohe (Kawenga Tauhohe Pūmau Q)
- Mātāpono: Ka whakamahi i ngā inductors hei whakapau i te mana tauhohe.
- Ngā Painga: Ka taea te whakarato kawenga tauhohe.
- Ngā Huakore: Kāore i te whakamahia ko ia anake, engari ka honoa ki ngā kawenga ātete.
3. Kawenga Ātete/Tauhohenga Whakakotahi (Kawenga R+L, e whakarato ana i te P me te Q)
- Mātāpono: Ka whakauru i ngā pēke ātete me ngā pēke tauhohenga, ka taea ai te whakahaere motuhake, te whakahaere ngātahi rānei i te kawenga hohe me te kawenga tauhohe.
- Ngā Painga: Ko te otinga pai mō ngā pokapū raraunga. Ka taea te whakatauira i ngā kawenga whakauru tūturu, me te whakamātautau whānui i te mahi whānui o te huinga whakaputa hiko, tae atu ki te AVR (Aunoa te Pūnaha Whakahaere Ngaohiko) me te pūnaha kawana.
- Ngā Huakore: He nui ake te utu i ngā kawenga ātete parakore.
- Tuhipoka Kōwhiringa: Kia aro ki tōna awhe Mana Tauwehe (PF) ka taea te whakarerekē, me whakarerekē i te nuinga o te wā mai i te 0.8 whakaroa (whakauru) ki te 1.0 hei whakatauira i ngā momo kawenga rerekē.
4. Utaina Hiko
- Mātāpono: Ka whakamahi i te hangarau hikohiko mana hei whakapau i te pūngao, hei whakahoki rānei ki te whatunga hiko.
- Ngā Painga: He tino tika, he ngāwari te whakahaere, he kaha ki te whakaora i te pūngao (te penapena pūngao).
- Ngā Huakore: He tino utu nui, e hiahiatia ana he kaimahi tiaki tino pūkenga, ā, me whai whakaaro ki tōna pono.
- Horopaki Taupānga: He pai ake mō ngā taiwhanga, ngā whare hanga rānei i te whakamātautau tiaki i te papaanga i roto i ngā pokapū raraunga.
Whakamutunga: Mō ngā pokapū raraunga, me whiriwhiri he «Utaina Hē Ātete/Tauhohe (R+L) Whakakotahi» me te mana aunoa atamai.
4. Whakarāpopototanga o ngā Hipanga Kōwhiringa
- Whakatauhia ngā Whakaritenga Whakamātautau: Mō ngā whakamātautau mura anake, me whai tiwhikete mahi kawenga katoa rānei? Me whai pūrongo whakamātautau aunoa?
- Kohikohia ngā Tawhā o te Huinga Hanga Pūnaha: Whakarārangihia te mana katoa, te ngaohiko, te auau, me te tauwāhi atanga mō ngā kaihanga pūnaha katoa.
- Whakatauhia te Momo Kawenga Hē: Tīpakohia he kawenga hē R+L, atamai, whakamatao-wai (ki te kore e tino iti te mana, ā, he iti hoki te tahua).
- Tātaihia te Pūngao Mana: Te Pūngao Utaina Hē Katoa = Te mana kotahi waeine nui rawa × 1.1 (1.25 rānei). Ki te whakamātautau i tētahi pūnaha whakarara, me ≥ te kaha katoa o te mana whakarara.
- Kōwhiria te Tikanga Whakamatao:
- Te mana nui (>800kW), te iti o te wāhi rūma taputapu, te aro ki te haruru: Kōwhiria te whakamatao wai.
- He iti te mana, he iti te tahua, he rawaka te wāhi hauhautanga: Ka taea te whakaaro ki te whakamatao hau.
- Arotakehia te Pūnaha Whakahaere:
- Me tautoko i te utaina aunoa o ngā taahiraa hei whakatauira i te whakauru kawenga tūturu.
- Me kaha ki te tuhi me te whakaputa i ngā pūrongo whakamātautau paerewa, tae atu ki ngā ānau o ngā tawhā matua katoa.
- E tautoko ana te atanga i te whakaurunga ki ngā pūnaha Whakahaere Whare, ki ngā pūnaha Whakahaere Hanganga Pokapū Raraunga rānei (DCIM)?
- Whakaarohia te Tāutanga Waea Pūkoro me te Tāutanga Pūmau:
- Tāutanga Pūmau: Ka tāutahia ki roto i tētahi rūma motuhake, ki tētahi ipu rānei, hei wāhanga o te hanganga. He pūmau te waea, he ngāwari te whakamātautau, he ātaahua te āhua. Ko te kōwhiringa pai mō ngā pokapū raraunga nui.
- Whakamau ki te Waka Pūkoro: Mēnā ka whakamaua ki runga i te wakatō, ka taea te whakamahi mō ngā pokapū raraunga maha, mō ngā waeine maha rānei. He iti ake te utu tīmatanga, engari he uaua te whakatinanatanga, ā, me whai wāhi rokiroki me ngā mahi hononga.
5. Ngā Tikanga Pai me ngā Taunakitanga
- Mahere mō ngā Atanga Whakamātautau: Hoahoa i mua i ngā kāpata atanga whakamātautau kawenga rūpahu i roto i te pūnaha tohatoha hiko kia haumaru, kia māmā, kia paerewa hoki ngā hononga whakamātautau.
- Otinga Whakamatao: Mena he wai te whakamatao, kia pono te pūnaha wai whakamatao; mena he hau te whakamatao, me hoahoa he paipa whakaputa hau tika hei ārai i te hau wera kia hoki anō ki roto i te rūma taputapu, kia kore ai hoki e pā ki te taiao.
- Haumaru Tuatahi: Ka puta he pāmahana tino teitei i ngā kawenga rūpahu. Me whai taputapu haumaru pērā i te ārai i te pāmahana nui me ngā pātene aukati ohorere. Me whai whakangungu ngaio ngā kaiwhakahaere.
- Whakamātautau Auau: E ai ki te Uptime Institute, ko ngā paerewa Tier, ko ngā taunakitanga rānei a te kaihanga, ka whakahaerehia i ia marama me te kawenga whakatauranga kāore i raro iho i te 30%, ā, ka whakahaerehia he whakamātautau kawenga katoa i ia tau. Ko te kawenga teka he taputapu matua hei whakatutuki i tēnei whakaritenga.
Taunakitanga Whakamutunga:
Mō ngā pokapū raraunga e whai ana i te wātea nui, kaua e penapenahia te utu mō te kawenga rūpahu. Ko te haumi ki tētahi pūnaha kawenga rūpahu kua pumau, he rahi tika, he R+L, he atamai, he whakamatao-wai he haumitanga e tika ana hei whakarite i te pono o te pūnaha hiko nui. Ka āwhina i te tautuhi i ngā raruraru, te ārai i ngā hapa, me te whakatutuki i ngā whakaritenga whakahaere, tiaki, me te arotake mā roto i ngā pūrongo whakamātautau whānui.
