Te Mārama i te Sulfur Hexafluoride (SF6): Te Tūrangi o te Wā e Hīkina nei i te Tauira Hiko

Te māngai whakarara, e mohiotia ana i te wā rānei ki te SF6, he āhua matū inaianei i te ao o ngā mahi tūmomo hiko. Ki te pūnaha herekeemi SF6, ka noho tēnei āhuatanga hei hāpai kōwhiri, karekau i te wehi, karekau i te mate, ā, karekau hoki i te whakaawe i te ahi i ngā wāhanga wea me te paongaro. He 146.055 te mana moelēweherehe o te SF6, ko te mana tupeka 6.0886 kg/m3 i te 20°C me te 0.1 MPa, e ai ki reira, he rima retinga rawa tonu te mīria o tēnei i runga i te hā. Ko tēnei whenua tino mīharahara, i tārewa ai i te whakauru o tana rārangi mata-ono me te mīhini nui o tana hononga, e whai take ana ki te tūpato nui o te SF6, ā, i ngā wāhi kei reira ka kore ai e tae te werawera i te 180°C. Ko tana tirohanga ki ngā rara hiko e taea ana ki te tirohanga o te niuterena, ka whakapakari ake i tana whakamahi.

I te tekau ma rima tekau o 1960, i whakamahia ngatahi te sulfurahexafluoride hei uwha hoki i nga mea whakaute mati roa. He tino pai rawa te noho o te wae SF6 i runga i te itinga whenua i pai ai i te whakatupu whatunga mati roa tuatahi. Ko te hanga iti nei e whai ana i te pai me te whakarite haere i nga whiuwhiu whakaute, inarahi i nga taiao me te āhuatanga o ngā rangi e paku whakarerekētanga. Noho anō te mea ko SF6 ka whai wāhi nui ki te whakamahi i te take waewae (UHV) me te take waewae nui atawhai (EHV), heoi anō ka kitea i a ia hoki i waenganui i nga takiwa whakahaere. Ka nui ake te whakamahitanga o nga kauwhata ara me nga ring main units kei raro i te uwha SF6, e whakaatu ana i te mohiotanga o tenei hunga whakangungu.

Kei roto i te ao o te whakamana huringa, e ai ki ngā paihere SF6, he maha ngā painga o ngā raraunga whakamana i tēnei, pērā i ngā huinga iti me te mohiotanga nui o te whakamana. E whai take ana enei tuhinga ki te whakarite i a rātou hei whakamahere mō ngā wāhi e huringa ana i te māmā o te whenua, kia noho tika hei whakamahi mo ngā wharepū wai, kei reira kaore te whakamahi i ngā rauwhiringa kiko rīpeka hei tika. No reira, e ai ki ngā whakapuaki SF6, e āhei ana ia ki te whakaeke i te ahi me te pūngao, kia whakaritea hei whakamahi mo ngā wāhi katoa me ngā whare tu tonu nui, kei reira ko te haumanu kotahi hei whakaaro.

Ki te whakamua me te matataki rangahau, kua whiwhi i ngā whakatūhanga e pā ana ki ngā whakaruru hiko torotoro-ihi nui ā-tau e whakapakari nei i te SF6, e tuhituhi ana ki tētahi āheinga i mua kei reira e āhei ana ngā whakaruru hokohoko katoa i te ara i roto i te whakariterite o ngā whakaruru. Ko te whitiwhiti atu ki te SF6 he tohu i tana mana hei wāhanga matua i roto i te nohonga hiko ā-rōpū, whakamahia ai ngā whakaaetanga e pai ana i te mahi, te haumaru, me te tiakina.

Ko te mutunga, ko te hāpara ono (SF6) he mea pai rawa hei kaiwhakarere i te rāngai i roto i ngā tūnga hiko torotoro-ihi. Ki runga i ōna ahuatanga ā-wāhanga me ōna pūtake whaihua, ka whakatipu tonu te SF6 i te tūrangi o te hanganga hiko, whakatupu i ngā whakataetae e āhei ana ki te whakapai i ngā rāngai hokohoko hiko puta noa i te ao.
