arotakenga o ngā Kaiwawao Ara Iahiko
He taputapu matua te Pūwhakawātea Arahiko i roto i te pūnaha hiko e whakamahia ana hei tiaki me te whakahaere i ngā arahiko. Ka taea e ia te kati, te kawe me te wawahi i te iahiko i raro i ngā āhuatanga noa, i ngā āhuatanga hapa rānei. Ko ōna mahi matua ko te tiaki i te taumaha rawa, te tiaki i te arahiko poto, te tiaki i te ngaohiko iti, me ētahi atu. He rite tonu ki te huinga o ngā fiusi me ngā whakawhiti wera nui/iti iho, engari he nui ake tōna pono me tōna āheinga ki te whakamahi anō.

Ngā tawhā āhuatanga matua
Ngaohiko whakatauranga (Ue): Ko te ngaohiko teitei rawa atu e mahi noa ai te kaiwawao hiko, pērā i te 220V, 380V, me ētahi atu. 37

Iahiko kua whakatauria (In): Ko te iahiko mōrahi ka taea te kawe haumaru i roto i te wā roa, me nui ake i te iahiko whakahaere o te ara iahiko mā te 35%.

Te kaha pakaru (Icu/Ics): Ko te kaha pakaru poto mutunga rawa (Icu) e pā ana ki te kaha ki te pakaru i te iahiko poto mōrahi i te wā kotahi. Ko te kaha pakaru whakahaere (Ics) e pā ana ki te paepae iahiko ka taea tonu te whakamahi i muri i te pakaru. I te nuinga o te wā, me whai Ics ≥50%Icu ngā pakaru hiko anga, ā, me whai Ics ≥25% ICU ngā pakaru hiko kēhi kua whakakikoruatia.

Iahiko ātete-poto (Icw): Ko te kaha o te kaiwawao hiko ki te ātete i te iahiko ara-poto i roto i tētahi wā kua tohua me te kore e pakaru.

II. Te Whakarōpūtanga o ngā Kaiwawao Ara Iahiko
1. Mā te taumata ngaohiko
Ngā whati hiko hiko-teitei: E whakamahia ana i roto i ngā pūnaha 3kV me runga ake. Ko ngā mea e whakamahia whānuitia ana mō te tinei i te pewa ko te whanariki hexafluoride (SF6), te korehau, te hinu, me ētahi atu. 4

E toru ngā momo o ngā whati hiko iti-ngaohiko: te momo anga (ACB), te momo pouaka whakarewa (MCCB), me te momo iti (MCB). 57.

2. Mā te hanganga me te tono
Wāwāhi ara iahiko momo anga (ACB)
Iahiko kua whakatauria: 200A ki te 6300A, he parenga wāhanga-whā (whakaroa roa, whakaroa poto, tere tonu, me te hapa whenua), e whakamahia ana mō te tiaki i ngā pana matua i roto i ngā pūnaha tohatoha, i ngā taputapu kaha nui rānei.

Wāwāhi ara iahiko pouaka whakarewa (MCCB)
Hanganga kiato, he auhiko whakatauranga 10A ki te 1600A, he pai mō te tiaki i te ara iahiko peka. Ka tautoko te MCCB hiko i te tiakitanga whiriwhiri, ā, kei ētahi tauira he mahi raka rohe 57.

Pūwhakapakari Ara Iahiko Iti (MCB)
E whakamahia ana i roto i ngā ara iahiko pito i raro i te 125A (pēnei i ngā mea o te whare me ngā mea arumoni), e wātea ana i roto i ngā whakatakotoranga 1P ki te 4P, ā, e tautoko ana i te tiaki i te taumaha rawa, te ara iahiko poto me te turuturu.

3. Pēhia te hangarau tinei arc
Pakaru hiko korehau: He tere te tinei i te pewa, he roa te ora mahi, he pai mō ngā āhuatanga mahi auau 4.

Pūwhakaweto hiko SF6: He tino pai te mahi ārai wera me te tinei pewa, ā, e whakamahia ana i roto i ngā pūnaha ngaohiko teitei. Me whakamātautau tonu te parakore o te hau.

Iii. Ngā Mātāpono mō te Kōwhiringa o te Kaiwhatu Ara Iahiko
Whakatauritehia ngā tawhā ara iahiko
Ngaohiko whakatauranga ≥ ngaohiko raina, iahiko whakatauranga ≥ iahiko kawenga mōrahi, kaha pakaru ≥ iahiko ara-poto e tumanakohia ana 57.

Te urutaunga momo kawenga
Me whai whakaaro te tiakitanga o te motuka ki te iahiko tīmatanga (ko te uara tautuhinga o te wehenga inamata he 1.35 ki te 1.7 ngā wā o te iahiko tīmatanga). E ono ngā wā o te iahiko kawenga e tangohia ana e te ara iahiko rama, arā, 78.

Te whakaritenga whiriwhiri
Me tutuki i ngā whati hiko o runga me o raro te rerekētanga wā (pēnei i te rerekētanga mahi whakaroa-poto ≥0.1s) me te rerekētanga iahiko (te iahiko mahi o te taumata o runga ≥ 1.2 ngā wā o te taumata o raro) kia kore ai e hinga rawa te taumata.

Te urutau ki te taiao
Mō ngā taiao teitei, haumākū, pāmahana tiketike rānei, me whiriwhiri he tauira motuhake, ā, me whakarerekē te iahiko whakatauranga (me whakaiti te kaha ina neke atu te pāmahana i te 40℃). 13.

IV. Te Whakamātautau me te Tiaki i ngā Kaiwawao Ara Iahiko
Ngā tūemi whakamātautau matua
Ātete pā pūmau/hihiri: Kitea te ngaronga pā 12.

Te tātari āhuatanga mīhini: Te wā whakatuwheratanga me te wā kati, te tere me te wā kotahi 14.

Mahi ārai: Ātete ki te whakamātautau ngaohiko, te kite i te nekehanga korehau (mō ngā kaiwawao ara iahiko korehau) 14.

Manatoko mahi tiaki: Whakatikatika i ngā uara mahi taumaha me ngā mahi takahi ara iahiko-poto 8.

Ngā kaupapa matua o te tiaki
Tirotiro auau: Te pēhanga hau (kaiwawao ara iahiko SF6), te tango i ngā hononga, te whakahinuhinu i te mīhini 48.

Ngā whakamātautau ārai: I whakahaerehia kia rite ki ngā paerewa pēnei i te GB/T 1984 me te GB 14048, ia tau ki te 3.

Te whakahaere hapa: Mēnā ka kore te hinu, ka wera rawa, ka pahū rānei, me wehe te ahi i roto i te wāhi ohorere, ā, me tirotirohia ngā raruraru o te pūnaha tinei ahi whakapā, o te pūnaha tinei ahi rānei. 4.

V. Tātaritanga o ngā Raru Noa
Te rerekētanga i waenga i te kaiwawao hiko me te momotu
Ko te momotu hiko (QS) ka whakamahia anake hei wehe i te pūtake hiko, ā, kāore he āheinga tinei pewa. Ka taea e te kaiwawao hiko (QF) te tapahi i te iahiko hapa o te 12.

Te Hiranga o te Icu me te Ics
E whakaata ana te Icu i te kaha pakaru mutunga kore, ā, e whakaata ana te Ics i te pono o te mahi tonu. Ka arotahi ngā raina matua ki ngā Ic, ko ngā raina peka ia ka arotahi ki te Icu8.

Te kōwhiringa o ngā whati ara iahiko whakawhāiti-auau
Tātaitia te ahotea wera o te taura mā roto i te pihi whakawhāiti-au, ā, me whakarite kia nui ngā tauira he tere te pakaru (pērā i ngā kaiwawao hiko korehau) 78.

I hē te mahi a te parenga turuturu
Nā te hekenga o te whakamarumaru o te raina, te ngoikore rānei o te whenua, me kimi te ia turuturu me te whakatika i te paepae mahi (mai i te 30mA ki te 300mA te nuinga).
