Ko ngā RMU kua whakamau hau (GIS) nui ana te mahi i ngā tukutuku hiko o ngā tāone iti. Whakamahia e ēnei pūnaha te hau kirihi hauhau rino, e āki ai kia iti ake te wāhi e 40% te rahi ki te tata ki ngā tauira āhua tūmatanui (AIS). Ahakoa rā, ka taea tonu e rātou te pupuri i ngā nama pakaru poto e rite ana ki te 25kA, pea rānei he iti ake. He aha te take kino? Ko te utu tuatahi mō ngā taputapu GIS e 15 ki te 20% te nui ake. Engari ina kāore he wāhi hei whānuitanga i ngā wāhi hiko o ngā tāone, ka hiahia noa te hoahoa iti nei. Mō ngā tūwāhi kaikirihana kei reira kāore te whenua i te raruraru, ko te nuinga o ngā kaiwhakahaere e mau ana ki ngā RMU AIS. Ko ngā utu tiaki tiaki e 10 ki te 15% pea te iti iho i te rua tekau tau e ai ki ētahi rangahau tāpoi hōhonu mai i te tau 2023 mō ngā waka wā ora.
Ko ngā RMU me te whakapuru kōhatu e horoi ana i ngā arawhata epoxy kia wātea tonu mai ngā tukunga SF6 ka taea ai te paerewa atamira IP67, nā reira he nui ake te haumāruratanga ki ngā wāhi e tūpono ana te awanui. E mātara ana ngā tūmomoa mara i te pai ake o te haumāruratanga ki te 35%. Ko te hiahia hoki ki ngā pūnaha paraire e huinga ana i te hangarau whakamarumaru vacuum me ngā matērahi whakapuru kōhatu e tipu haere ana. E whakaatu ana te rangahau mākeke mai i MarketsandMarkets ko ēnei whakatipuranga paraire ka kitea i te tīmataka tauaroto o te 9.2% tata ki te tau 2030. He aha te mea e tino tā te hiahia ki ēnei ara hou? Ka iti noa ngā rere o ngā huakita parakore ki te 92% ina mātara ki ngā kapa GIS tawhito. Ko tēnei momo mahi e āwhina ana i ngā kaihanga kia ū ki ngā tikanga maroke pērā i te Ture F-Gas o te EU 517/2014 kia kaua e iti ake te uara whakahaere.
Ko te whakauru RMU e hiahiatia ana te whanaketanga mō te taiao:
E ai ki tētahi pūrongo ahuwhenua 2024 e ananaritia ana ngā whakaurunga o ngā whatunga hihiri, i te ita 32% te wā kua pau i ngā whatunga RMU i ngā whatunga taone.
Ko te pono kōrero mō te pūkenga o tētahi kaihanga e āwhina ana i te wāhi e taea ai te hanga i ērā rāwekenga RMU tino-tika e ōrite ana ki ngā whakamahinga motuhake. Ka taea e ngā inijeita me ngā mōhiohio hoki te whirihora mō ngā tāpoi rerekē, te whakahaere i ngā take taiao rerekē, me te whai i ngā here here tūhura katoa. E ai ki tētahi pūrongo i te tau ki muri mō ngā whanaketanga hiko, i kitea e ngā kamupene i mahi tahi me ngā kaihanga matatau he toronga 33% nui ake i te wāhi noho o te hiko. Ki te titiro ki ngā mea e wehe ai tētahi kaihanga? He nui te utu ki te rangahau me te whanaketanga. Heoi anō hoki ngā taputapu whakamātau kaha hei whakamātau i ngā hoahoa i mua i te whakaputa. Me kaua hoki te wareware i ngā tīmataka ahumahi pērā i IEC 62271 me IEEE C37.20.3 e tiwhikia ai te haumātauranga me te whakapono puta noa.
Ko ngā kaihanga matua e whakamahi nei i ngā hoahoa RMU takitahi e taea ai ngā whakapai ake itiiti kaore he huringa punaha katoa. Mā tēnei ara ka taea e ngā kamupene hiko:
Ko te rangahau a te ahumāra e whakaatu ana ko ngā whare pūtaha takitahi e 57% te itinga o ngā utu whakatipungia i te roanga atu ki ngā kapa tūmau.
Ko te whakamahi i ngā anga Utu Tino o te Whakahaere (TCO) e āwhina ana i ngā kamupene hiko kia āhua tika i waenganui i ngā utu tuatahi me te uara roanga atu ina tīmata ana ki te kōwhiri i tētahi kaihanga RMU. Ko ngā kaihanga matua e tuku ana i ngā rarangi manawanui 10–15 tau e tautokona ana e ngā tīketanga mahi, e iti ai te exposure moni mai i ngā herenga marino.
Ko ngā kirimana ratonga whānui e whai pūnga ana i te tiaki aukati, te tirohanga tawhito, me te wātea o ngā wāhanga kee e hua ai te noiho tūponotia o te punaha. I te rangahau a Ponemon 2023 ka kitea ko te 72% o ngā kaitiaki ripa e tautoko ana i ngā kaihanga e tuku awhina hangarau 24/7 hei whakaiti i te wā kore-āhua.
Ka roa ake te ora o te RMU 30–40% mā te tiaki aukati, ā, ka iti ake ngā whakatikatika mataara 27% ia tau mā ngā tatauranga matapae. Ko ēnei ratonga hei whakapono i te aronga tonu ki ngā paerewa IEC 62271 e huri haere ana, ā, hei āwhina i te pupuri i ngā ngaro kaha i raro ake i te 1,5% ki ngā whatunga hiko waenga.
Ahakoa e 15–20% ake pea te utu tuatahi mō ngā RMU matua, he 35% iti ake te huinga utu o te ora tonu i te nuinga o ngā kōwhiringa tūtohi ki te pūtea nui ake nā te whakapono pai ake (he iti ake i te 0.1% te tere takahi i te tau) me te mariko mātauranga. Ko ngā umanga e whai ana i ngā tauānga TCO ka ripoata 22% ake te tere o te ROI mō ngā kaupapa whakarerekētanga whatunga i te nuinga o ērā e arataki ana anake ki te utu hoko.
