He aha ngā āhua o te pouaka tāwhai e whakamana ai i ngā whakamārama whakamātautau i waho?

Te Whakamātūtū i te Ao me ngā Āhuatanga o te Tau: Te Whakamātūtū i te Pūmau o te Poukai i te Wā Roa

Ngā Mātū HDPE me PP: Te Whakamātūtū i te Ao, te Whakamātūtū i ngā Huringa Tāwhai, me te Pūmau i te Ao

Kua riro ngā rauemi HDPE me PP hei kōwhiringa nui mō te hanga pouaka pourewa i ēnei rā nā te mea he pai ake te pupuri o tō rātou hanganga rāpoi ngota i te wā. Ina tāpiri ngā kaiwhakanao i ngā aukati UV, ka hanga e rātau he whakangungu ki te kino o te rā. I muri i te noho tata ki te 10,000 haora ki te ra, ka mau tonu ēnei rauemi ki te 95% o to rātau kaha taketake, e whakawhiti ana ki te tekau tau te utu o te whakaeke i ngā wāhi ki te rangi mahana. Ko te mea e tino kitea ana ēnei kirihou ko te āhua o te whakahaere i ngā huringa pāmahana i waenganui i te -30 ki te 60 nekehanga Celsius, me te kore e pakaru. Ka taea e ngā mekameka polymer i roto i a rātau te ngaru kia pai ai te whakawhānui i te wā e wera ana, me te whakapeka i te wā e makariri ana. I whakaritea ki ngā kōwhiringa whakarewa, raima rānei, kāore te HDPE me te PP e waikura, e pakaru rānei ina whakaekea ki te wai tote, ki ngā matū rānei e kitea nuitia ana i roto i ngā mahi ahuwhenua. Ko ngā whakamātautau tūturu i ngā pāmu puta noa i ngā rohe rerekē e tohu ana ka mau tonu te kaha o ngā whare HDPE ki te tu atu i te 25 tau, i te mea he āhua kore te maitai paerewa kāore he paninga i muri i te 12 tau i raro i ngā āhuatanga ōrite.

I tāwāhi i te tohu: He aha ngā take kia kāore te whakamātautau ASTM G154 i te UV e whakamārama ai i te whai hua i te pūnaha i te 10 tau i ngā wāhi ā-ao

Ahakoa he whakamātautau pāwhara o te UV ASTM G154 he uta mō te whakamātautau i ngā kōpae, ko ngā whakamātautau ā-ao i ngā taumata o te ao hāngai e whakapāpā ana i ngā āhua o te pakaru kāore i ngā whare whakamātautau.

Ko ngā āhua whakamātautau tūmatua mātua he rite tonu ki te whakamātautau i ngā whāinga o ngā pānga maha i mahi tahi. He tauira, ko te whakaata o te UV e whakamāngai ana i ngā kōpae hāngai kia whakamātautau, ā, ka whakawhitinga i te whakamātautau i te wai i ngā wāhi e hono ana ngā wāhi. Ko ngā ripoata mai i ngā rohe wāhi wai e whakaatu ana i tēnei: he rite ki tēnā i te rima o ngā pouaka e whakamātautau ana i te whakamātautau ASTM G154, ā, ka pakaru i te tau e whitu noa i te whakamātautau i ngā whakamātautau o ngā papa tāwhai, nā te pakaru o ngā whakamātautau i ngā wāhi mātua e kore e kitea i ngā whakamātautau tūmatua. Kia mārama ai ngā kaiwhakamahi i te tāwhai o ēnei hua i te wā, me whakamātautau ake ngā kaiwhakamahi i ngā mea i raro i ngā whakamātautau o ngā whare whakamātautau. Me tirohia ngā pāki, ngā kōwhai, i raro i ngā panonikanga o te hāngai, o ngā pānga mekanikā e kore e whakamātautau i te whare whakamātautau.

Te whakamātautau i te taupua o te taiao: Te tiaki IP i te pūpahi, i te wai, i ngā karawhiti i ngā pouaka tāwhai

Te whakamārama i te rerekētanga o IP66 me IP67: Ngā rerekētanga matua mō te pūmau o te pouaka huinga o ngā vālavi whakamātautau

Ko ngā whakamātautau o te Ingress Protection (IP) e whakamārama ana i te aha te pai o te pouaka tūhono hei whakamāni i ngā wāhanga o roto mai i ngā pānga o te taiao. Mō ngā pouaka huinga o ngā vālavi whakamātautau e whakamātautau ana i te ua, te puehu, i te whakamātautau kē i te wai, ko te whiriwhiri i waenganui i te IP66 me te IP67 he mea matua:

Ko te whakamātautau IP66 e mahi pūmau ana i ngā wāhi e maha ana ngā huinga wai kaha, ā, ina he uaua te ua i ngā tāwhirimārea. Ka tātai anō mātou ki te IP67, e whakapānui ana i te whakamātautau ake i ngā mea pērā i ngā taiwhenua, i ngā hāinga i te wā o te whakamātautau. Ko ngā pākenga e whai ana i ngā pārāwaha maha i rere mai i te whakamātautau i ngā taputapu, ka whakaatu mai i te roa o ngā taputapu i te 40% ake i te wā i rere mai i te whakamātautau IP67, nā te whakamātautau pai ake i ngā pārāwaha iti kia kore ai e uru mai. He mea whakaahua anō he mea tāwhai tonu, ahakoa he pai te whakamātautau IP o tēnei mea, kāore he uara mātua mēnā kāore ngā kōpae e hanga pūmau ana, i te wā hoki kāore ngā kōpae e whai ana i ngā rereketanga o te hāuru i te rere kē. Ko te whakamātautau kōpae iti he whakamāngungu i te whāinga katoa, ahakoa he aha te rārangi o te whakamātautau.

Te Whakamāngungu o ngā Hāri: Te Whakamātautau o ngā Pūhanga me te Whakauru i ngā Tārua Kīmata i ngā Pākenga Tāwhai

He tino hiranga te whakamārama pai i ngā kōpae kia whakakorea ngā raru pūhanga i te mahi i waho. I tēnei wā, ka taea ngā tapa o te pou (tower box) te whakamārama i ngā rahi rerehua o ngā kōpae, ā, kāore he pakaru i te kaha o te pou, nā ngā whakauru kia māmā te whakamahi, kia māmā te whakauru i ngā kōpae, kia kore ai ngā whakauru e whakamāhi i ngā pātai o ngā pātai. I muri i te whakauru i ngā kōpae, ka hanga ngā kōpae kua whakakīa (sealed cable glands) i ngā whakakīnga tata kia kore ai te wai e uru mai. I roto, he ngāwari hoki ngā kōpae kia whakamāhi i ngā whakauru kia kore ai ngā whakauru e whakamāhi i ngā whakauru i te wā e hiahia ana ngā kaimahi kia whakamāhi i ngā mahi whakamātautau i te rārangi.

Ko ngā pūnaha whakairi ātete ki te wiri e pupuri ana i ngā aho kia mau tonu ahakoa te taumahatanga o te whakawhānui wera, e āwhina ana ki te ārai i ngā take kōaro me ngā wehenga kāore e hiahiatia ana. I te wā e pā ana ki ngā hapa ā-rohe, ko ngā hapa tāutanga tonu te mea nui rawa. E whakaatu ana ngā pūrongo haumaru hiko hou mō te tau 2023 e toru o ngā raruraru makuku e whā i kitea i roto i ngā pouaka whakahaere whakainu, he mea tika ki te iti o te hiri i te wāhi e uru ai ngā aho ki te whare. He nui te take o te whiwhi i te nui tika o te torque ki aua nuts gland, me te whakarite kia pai te whakauru o ngā wāhanga katoa. Mā tēnei aro ki ngā taipitopito e pupuri te tohu tiaki IP o te whare i tōna wā katoa o te ora mahi, he mea e tika ana kia tino whakaūhia e ngā kaihanga i ngā hui whakangungu mō ngā kaiwhakawā.

Wāhanga FAQ

He aha ngā rauemi matua e whakamahia ana mō ngā pouaka pourewa, he aha hoki?

Ko nga rauemi HDPE me te PP e whakamahia nuitia ana mo nga pouaka pourewa na te kaha o to raatau kaha me te kaha ki te tu atu ki te hihi UV, nga rereketanga o te pāmahana, me te whakaeke matū.

He aha te whakamātautau ASTM G154?

Ko te whakamātautau ASTM G154 he huarahi whakauru kia whakamātautau i te whakaoranganga o ngā kōpae ki te UV. Heoi anō, e kore pea tēnei e whakaatu i te whaihua i te ao pūnaha, nā te mea kāore he whakaaro i ngā āhuatanga taiao katoa.

He aha te rerekētanga i waenganui i ngā whakamātautau IP66 me IP67?

Ko te IP66 he kōpae kua whakakaha kia kore ai te hūtoto, ā, e tiaki ana i ngā wai hauhau, i te wā hoki ko te IP67 he kōpae kua whakakaha kia kore ai te hūtoto, ā, e taea ana te whakamātautau i te wai moe paku wā.

He aha te take o te whakakaha tika o ngā pouaka tāwhai?

Ko te whakakaha tika he whakarere i te wai, ā, he take o ngā raru hāngā, ā, e whakamana ana i te mahinga o ngā pouaka tāwhai i ngā āhuatanga taiao.
