Tohungatanga ki ngā Taura Ārai Wai

1. He aha te taura ārai-wai?
Ko ngā taura ka taea te whakamahi i roto i te wai, ka kiia ko ngā taura hiko ātete-wai (ātete-wai). Ina whakatakotoria te taura ki raro i te wai, ka rumakina ki te wai, ki ngā wāhi mākū rānei, me whai mahi ārai-wai te taura, arā, me whai mahi ātete-wai katoa, kia kore ai e rumakina te wai ki roto i te taura, kia kino ai te taura, kia mau ai te mahi a te taura i raro i te wai mō te wā roa. Ko te tauira taura ātete-wai e whakamahia whānuitia ana ko JHS, nō te taura ātete-wai ringaringa rapa, ka wehea hoki te taura ātete-wai ki te taura hiko ātete-wai me te taura rorohiko ātete-wai, me ētahi atu, ā, ko ngā tauira ko FS-YJY, FS-DJYP3VP3.

2. Momo hanganga taura ātete wai
(1). Mō ngā taura matua-kotahi, takaihia terīpene aukati wai haurua-arahiki runga i te parepare whakamarumaru, takaihia te mea noarīpene aukati waiki waho, kātahi ka pēhi i te uhi o waho, kia pai ai te pa atu o te parepare whakarewa, takaihia noa te rīpene aukati wai haurua-arahi ki waho o te parepare whakamahana, kāore te parepare whakarewa e takai i te rīpene aukati wai, i runga i te taumata o ngā whakaritenga mahi ātete wai, ka taea te whakakī i te whakakī ki te whakakī noa, ki te whakakī poraka wai rānei. Ko ngā rauemi o te arai o roto me te uhi o waho he rite tonu ki ērā kua whakaahuatia i roto i te taura matua kotahi.

(2). Ka takaihia te rīpene konumohe kua pania ki te kirihou ki roto i te paparanga o waho, o te paparanga arai o roto rānei, kia kore ai e pāngia e te wai.

(3). Tukua te uhi o waho HDPE ki runga i te taura. Ko te taura XLPE kua whakamahanatia ki runga ake i te 110kV he uhi whakarewa hei whakatutuki i ngā whakaritenga ā-wai. He ātete katoa te pare whakarewa, ā, he ātete wai pai hoki. Ko ngā momo uhi whakarewa matua ko: te ringaringa konumohe pēhi wera, te ringaringa mata pēhi wera, te ringaringa konumohe kōpikopiko kua whakarewahia, te ringaringa maitai kōpikopiko kua whakarewahia, te ringaringa whakarewa tōia makariri me ētahi atu.

3. Taura ārai wai
Ko te ātete wai poutū me te ātete wai radial e rua. Ko te ātete wai poutū e whakamahia whānuitia ana heimiro ārai wai, paura wai me te rīpene ārai wai, kei roto i ēnei rauemi te tikanga ātete wai ka taea te whakawhanui i te rauemi, ina pakaru te wai mai i te pito taura, mai i te takotoranga rānei ki roto, ka tere te whakawhanui o te wai o tēnei rauemi hei ārai i te horapa atu i te taura roa, kia tutuki ai te kaupapa o te ārai wai roa o te taura. Ko te ātete wai radial ka tutukihia mā te whakaputa i te takotoranga kore-whakarewa HDPE, te pēhi wera rānei, te whakarewa me te kukume makariri i te takotoranga whakarewa.

4. Te whakarōpūtanga o ngā taura ārai wai
E toru ngā momo taura ārai wai e whakamahia ana i Haina:
(1). Ko te taura pepa-hinu te taura ātete wai tino noa. Kua whakakīia tōna whakamarumaru me ōna kaiārahi ki te hinu taura, ā, kei waho o te whakamarumaru he koti whakarewa (he koti mata, he koti konumohe rānei), koinei te taura ātete wai pai rawa atu. I mua, he maha ngā taura ruku wai (raro wai rānei) i whakamahi i ngā taura pepa-hinu, engari he iti noa iho ngā taura pepa-hinu nā te hekenga, he raruraru ki te turuturu hinu, ā, he uaua te tiaki, ā, i nāianei kua iti haere te whakamahinga.

(2). Ko te taura rapa ethylene propylene e whakamahia whānuitia ana i roto i ngā raina tuku hiko raro i te wai ngaohiko iti me te reo, nā tōna mahi whakamarumaru pai rawa atu, me te kore e manukanuka ki te "rākau wai". Ka taea e te taura hipoki rapa waikore (Momo JHS) te mahi haumaru i roto i te wai pāpaku mō te wā roa.

(3). Nā te mea he pai rawa ngā āhuatanga hiko, ā-mīhini me te ā-tinana o te taura hiko polyethylene whakawhiti-hono (XLPE), ā, he māmā noa te tukanga whakaputa, he māmā te hanganga, he nui te kaha tuku, he watea te tāutanga me te tiaki, kāore e herea e te maturuturunga me ētahi atu painga, ka noho hei rauemi whakamarumaru e whakamahia whānuitia ana, engari he tino tairongo ki te makuku, i roto i te tukanga hanga me te whakahaere mena ka whakakīia te whakamarumaru ki te wai, ka ngawari ki te pakaru "rākau wai", ka whakapoto i te roa o te mahi o te taura. Nō reira, me whai "hanganga ārai wai" te taura polyethylene whakawhiti-hono, inā koa te taura ngaohiko reo me te teitei i raro i te mahi a te ngaohiko AC, ina whakamahia i roto i te taiao wai, i te taiao mākū rānei.

5. Te rerekētanga i waenga i te taura ā-wai me te taura noa
Ko te rerekētanga i waenga i ngā taura ārai wai me ngā taura noa, kāore e taea te whakamahi i ngā taura noa ki te wai. Ko te taura ārai wai JHS he momo taura ngāwari hoki, he rapa te ārai, ā, ko te taura rapa noa te ārai, he maha ngā wā ka whakamahia te taura ārai wai JHS, engari kei roto i te wai, ka rere rānei ētahi mā te wai. Ko ngā taura ārai wai he 3 matua te nuinga, ko te nuinga o ēnei ka whakamahia ina hono ana i te papu, ka nui ake te utu o ngā taura ārai wai i ngā taura rapa noa, he uaua ki te wehewehe mēnā he ārai wai mai i te āhua, me kōrero koe ki te kaihoko kia mōhio ai koe ki te paparanga ārai wai.

6. Ngā rerekētanga i waenga i te taura ātete wai me te taura ātete wai
Taura ā-wai: ārai i te wai kei uru ki roto i te hanganga taura, mā te whakamahi i tētahi hanganga me ngā rauemi ā-wai.

Taura ārai wai: Mā te whakamātautau ka taea e te wai te tomo ki roto i te taura, ā, kāore e taea te uru ki te roa kua tohua i raro i ngā tikanga kua tohua. Kua wehea te taura ārai wai ki te aukati wai o te ara iahiko me te aukati wai o te matua taura.

Hanganga ārai-wai o te arataki: te tāpiri i te paura ārai-wai me te miro ārai-wai i te tukanga o te taura waea kotahi, ina uru te arataki ki te wai, ka whakawhanui te paura ārai-wai, te miro ārai-wai rānei ki te wai hei ārai i te urunga o te wai, he pono, he pai ake te mahi ārai-wai o te arataki totoka.

Hanganga ārai wai o te matua taura: ina pakaru te uhi o waho, ā, ka tomo te wai, ka whānui te rīpene ārai wai. Ina whānui te rīpene ārai wai, ka tere te hanga i tētahi wāhanga ārai wai hei ārai i te urunga atu o te wai. Mō te taura matua-toru, he tino uaua ki te whakatutuki i te ātete wai whānui o te matua taura, nā te mea he nui, he koretake hoki te āputa waenga o te matua taura matua-toru, ahakoa kua whakakīia te poraka wai, kāore i te pai te pānga ātete wai, e taunakihia ana kia hangaia ia matua kia rite ki te hanganga ātete wai matua-kotahi, kātahi ka hangaia te taura.
