I roto i te mara o ngā Waka Pūngao Hou (EV, PHEV, HEV), he mea nui te whiriwhiri i ngā rauemi mō ngā taura ngaohiko teitei ki te haumaru, te roa, me te mahi a te waka. Ko te polyethylene hono-whiti (XLPE) me te rapa silicone e rua o ngā rauemi whakamahana tino noa, engari he rerekētanga nui kei roto i te mahi pāmahana teitei, ngā āhuatanga whakamahana, te kaha miihini, me ētahi atu.
I te nuinga, e ruaXLPEme te rapa silicone e whakamahia whānuitia ana i roto i ngā taura o roto o ngā motuka. Nō reira, ko tēhea rauemi e pai ake ana mō ngā taura ngaohiko teitei i roto i ngā waka hiko hou?
He aha i hiahiatia ai he rauemi ārai wera-teitei mō ngā taura hiko teitei mō ngā waka hiko hou?
Ko ngā taura ngaohiko teitei i roto i ngā waka hiko hou e whakamahia nuitia ana mō te pākahiko, te motuka, te pūnaha whakahaere hiko, me te pūnaha utu, me ngā ngaohiko whakahaere mai i te 600V ki te 1500V, teitei ake rānei.
Ko te tikanga me whai ngā taura i ēnei:
1) He mahi whakamarumaru pai rawa atu hei ārai i te pakaru hiko me te whakarite i te haumaru.
2) He ātete tino pai ki te pāmahana teitei hei tu atu i ngā taiao mahi uaua me te ārai i te pirau o te whakamarumaru.
3) He ātete kaha ki ngā ahotea ā-pūkaha, te piko, te wiri, me te kakahu.
4) He ātete pai ki te waikura matū hei urutau ki ngā taiao uaua me te whakaroa i te roa o te ratonga.
I tēnei wā, ko ngā paparanga whakamarumaru o ngā taura hiko teitei i roto i ngā waka hiko hou e whakamahi ana i te XLPE, i te rapa silicone rānei. Kei raro nei, ka whakatauritehia e mātou ēnei rauemi e rua.
Mai i te ripanga, ka kitea he pai ake te mahi a te XLPE e pā ana ki te ātete ngaohiko, te kaha miihini, te ātete koroheketanga, me te whakahaere utu, ko te rapa silicone ia he painga mō te ātete ki te pāmahana teitei me te ngāwari.
He aha te XLPE te rauemi pai mō ngā taura hiko teitei i roto i ngā waka hiko hou?
1) He Kaha Ake te Mahi Ārai: He nui ake te kaha o te rauemi ārai hiko XLPE (≥30kV/mm), ā, he pai ake te ātete ki ngā mōrearea pakaru hiko i roto i ngā taiao ngaohiko teitei ki te whakataurite ki te rapa silicone. Hei tāpiri, he iti te ngaronga hiko o te rauemi ārai hiko XLPE, e whakarite ana i te pumau o te mahi mō te wā roa, e pai ai mō ngā pūnaha hiko waka pūngao hou.
2) Ngā Āhuatanga Mīhini Pai Ake: I te wā e taraiwa ana, ka taea e ngā wiri o te tinana o te waka te whakararu i ngā taura. He kaha ake te kaha kume o te XLPE, he ātete pai ake ki te kakahu, ā, he pai ake te ātete ki te tapahi, he pai ake mō te whakamahinga roa me te whakaiti i ngā utu tiaki ki te whakataurite ki te rapa silicone.
3) Ātete Pakeketanga Pai Ake: He tino pai te ātete o te rauemi whakamahana XLPE ki te koroheketanga o te rākau wai, kia mau tonu ai te taura i roto i ngā taiao haumākū nui me te papa hiko teitei. He mea nui tēnei mō ngā waka hiko hou, inā koa i roto i ngā tono kawenga nui pēnei i ngā kete pākahiko ngaohiko teitei me ngā pūnaha utu tere.
4) Ngāwari noa iho te whakamahi hei whakatutuki i ngā whakaritenga waea: Ki te whakatauritea ki te rapa silicone, he ngāwari noa iho te whakamahi a te XLPE, e whakataurite ana i te ngāwari o te waea me te kaha ā-ringa. He tino pai tana mahi i roto i ngā tono pēnei i ngā taura hiko-tiketike i roto i te waka, ngā raina whakahaere motuka, me ngā hononga pākahiko.
5) He iti ake te utu: He iti ake te utu o te XLPE i te rapa silicone, e tautoko ana i te hanga papatipu. Kua noho hei rauemi matua mō ngā taura ngaohiko teitei i roto i ngā waka hiko hou.
Tātaritanga o te Horopaki Taupānga: XLPE me te Rapa Silicone
He pai ake te whakataetae o te XLPE i roto i te tono taura ngaohiko-tiketike mō ngā waka hiko hou, me tōna ātete ngaohiko tino pai, tōna kaha miihini, me ōna painga utu.
I te haere tonu o te whanaketanga o ngā hangarau waka hiko hou, kei te whakapai ake hoki ngā rauemi XLPE kia tutuki ai ngā tono teitei ake i roto i ngā horopaki tono:
1) XLPE Ātete-Pāmahana-Teitei (150℃-200℃): He pai mō ngā pūnaha taraiwa hiko tino whai hua o te whakatupuranga e whai ake nei.
2) Polyethylene Honohono Kore-Halogen Iti-Paowa (LSZH): E tutuki ana i ngā paerewa taiao mō ngā waka hiko hou.
3) Paparanga Parepare Arotau: Ka whakarei ake i te ātete ki te pokanoa hikohiko (EMI) me te whakapai ake i te hototahi hikohiko whānui (EMC) o te waka.
I te nuinga o te wā, kei te noho te XLPE hei tūranga matua i roto i te rāngai taura ngaohiko teitei mō ngā waka hiko hou nā te mea he pai rawa te mahi whakamahana, te ātete ngaohiko, te kaha miihini, me ngā painga utu. Ahakoa he pai te rapa silicone mō ngā taiao pāmahana tino tiketike, nā te utu nui ake ka pai mō ngā hiahia motuhake. Mō ngā taura ngaohiko teitei matua i roto i ngā waka hiko hou, ko te XLPE te whiringa pai rawa atu, ā, ka taea te whakamahi whānui i roto i ngā wāhi matua pēnei i ngā taura pākahiko, ngā taura motuka ngaohiko teitei, me ngā taura utu tere.
I roto i te horopaki o te whanaketanga tere o te umanga waka hiko hou, me whai whakaaro ngā kamupene ki ngā āhuatanga pēnei i ngā horopaki tono, ngā whakaritenga ātete pāmahana, me ngā tahua utu i te wā e whiriwhiri ana i ngā rauemi taura ngaohiko teitei hei whakarite i te haumaru me te roa o ngā taura.
