Ngā Pūrongo Ahumahi

He mea nui te whakarōpūtanga o ngā taumata ngaohiko i roto i ngā pūnaha hiko hei whakarite i te tuku hiko, te tohatoha, me te haumaru whai hua. Mā ngā taumata ngaohiko ka whakatau te kawe hiko puta noa i ngā whatunga hiko, ka whakatauritea kia rite ki te whaihua hangarau me te whaihua ōhanga, ā, ka urutau ki ngā tono kanorau. Ka tūhuratia e tēnei tuhinga ngā paearu me ngā paerewa e whakahaere ana i ēnei whakarōpūtanga, me te arotahi ki ​ngaohiko teitei (HV),ngaohiko waenga (MV),ngaohiko iti (LV), mengaohiko tino teitei (UHV)He mea nui te whakarōpūtanga o ngā taumata ngaohiko i roto i ngā pūnaha hiko hei whakarite i te tuku hiko, te tohatoha, me te haumaru whai hua. Mā ngā tohu ngaohiko e whakatau te kawe hiko puta noa i ngā whatunga hiko, e whakatauritea ana mō te whaihua hangarau me te whaihua ōhanga, ā, e urutau ana ki ngā tono kanorau. Ka tūhuratia e tēnei tuhinga ngā paearu me ngā paerewa e whakahaere ana i ēnei whakarōpūtanga, me te arotahi ki ​ngaohiko teitei (HV),ngaohiko waenga (MV),ngaohiko iti (LV), mengaohiko tino teitei (UHV).

Hei kaihanga matua e tohunga ana ki ngā whakawhiti hiko waenga me te teitei, e harikoa ana a JZP Power Transformer ki te whakapuaki i tō mātou whai wāhi ki te ENLIT Europe 2025—te huihuinga matua o te ao mō te auahatanga pūngao. Mai i te 18–20 o Noema, 2025, ka whakaatuhia e mātou ā mātou otinga hou ki te Bilbao Exhibition Centre (48100 Bilbao, Bizkaia, Spain). Tirohia mātou ki te Booth 3.F122 kia kitea ai te āhua o tā mātou hanga i te heke mai o te tuku me te tohatoha hiko.

I roto i te ao hihiri o ngā hanganga pūngao o te ao, ko JZP te tino tohunga ki ngā whakawhiti hiko reo-rahi me te ngaohiko-teitei—te pou tuara o te tuku hiko, te tohatoha, me te whakamahinga whai hua. Me ngā tekau tau o te tohungatanga, te hangarau hou, me te whakapau kaha ki te kounga, ka whakamanahia e mātou ngā ahumahi, ngā ratonga hiko, me ngā kaupapa puta noa i te ao kia tutuki ai ngā otinga pūngao pono, pumau, me te utu-whai hua.

Ko te taputapu whakawhiti te pou tuara o ngā pūnaha hiko ngaohiko waenga me te teitei (MV/HV), e mahi ana i ngā mahi matua e toru mō ngā whakawhiti hiko:

• ;Tohatoha Mana: Ka arahi i te hiko mai i ngā whakawhiti hiko ki ngā kawenga mā roto i ngā whāngai, ngā pae pahi, me ngā taputapu tiaki.
• ;Te Tiakitanga Hapa: Ka whakakore i ngā iahiko hapa i roto i ngā mirihekona (hei tauira, te kaha pakaru ara iahiko poto 31.5kA–40kA) hei ārai i te kino o ngā taputapu.
• ;Wehenga HaumaruKa whakarite kia haumaru te tiaki mā roto i ngā raka ā-mīhini me ngā tikanga whakapūmau whenua.

Hei tauira, me whai i te iti rawa o te tawhiti ā-wāhanga-ki-whenua o te 125mm (haumātao) 40mm rānei (haumātao) mō tētahi pūnaha 12kV hei ārai i te āwhata.

;Tātari Taipitopito o ngā Momo Whakawhiti Hikohiko Mana Ngaohiko M&H, ngā Whirihoranga Hanganga, me ngā Tawhā Matua

Kei te whakaaturia te āhua maha-taumata o te Pūtake Kore-Whakapiri (NPC). Haunga te āhua NPC kua whakapirihia ki te diode, kei roto hoki i ngā āhua NPC te momo pūnga rere me te momo whakapiri ranu, me ētahi atu. Heoi, nā te nui o te rahinga pūnga, kei te whakamahi tonu ngā āhua NPC i ngā taputapu whakawhiti kore mahi, kaha rānei mō te whakapiri. Hei tauira, ko te āhua maha-taumata kua whakapirihia ki te diode, i roto i te āhua wāhanga whakatikatika toru-wāhanga, ko ia waewae wāhanga he transistors whakawhiti me ngā diode whakapiri, e honoa ana i te taha whakarara ki tētahi pahi DC ngaohiko-teitei kotahi. I whakaarohia e ngā tuhinga he āhua PET kotahi-wāhanga me tētahi wāhanga whakatikatika mā te whakamahi i tētahi ara iahiko kua whakapirihia ki te diode taumata-whā. Ka whaihia he pahi DC ngaohiko-teitei kotahi e ngā DAB whakauru-raupapa-putanga-whakarara, e whakaaturia ana. Ka taea te whakawhānui ake i tēnei āhua ki tētahi hanganga toru-wāhanga, ā, ka taea te whakarerekē i te maha o ngā taumata ngaohiko i runga i ngā taumata ngaohiko ātete taputapu me te taumata ngaohiko taha ngaohiko-teitei. Pērā i te āhua MMC, ka taea hoki te whakamahi i te āhua NPC i te wāhanga wehe, mā te hono i te pahi DC ngaohiko-tiketike ki te whakawhiti wehe, e whakaaturia ana. I whakamahia e ngā tuhinga he kaitahuri NPC kua herea-taio-taumata-toru ki te taha ngaohiko-tiketike o te kaitahuri resonant LLC, me te manatoko i runga i te tauira 166kW/2kV~400V. I whakamahia e ngā tuhinga he ara iahiko NPC kua herea-taio-taumata-toru ki te DAB wāhanga-toru, ā, ka tutuki i a rātou ngā āhuatanga ngaohiko me te iahiko DAB tino pai.

He rerekē ngā āhuahanga PET. I runga i te maha o ngā wāhanga hurihanga pūngao, ka taea te whakarōpū i ēnei ki ngā momo wāhanga-kotahi, wāhanga-rua, me ngā momo wāhanga-toru [7]. Ko ngā hanganga wāhanga-rua ko ērā he pahi DC ngaohiko-tiketike me ngā pahi DC ngaohiko-iti, e whakaaturia ana i te Pikitia 1.

I te whakaarotanga o te ariā ipurangi pūngao me te whānui o te whakamahinga o ngā hangarau e pā ana ki te whatunga atamai, ka tino piki ake te ōwehenga o ngā pūtake pūngao whakahou pēnei i te hau me te hiko photovoltaic i roto i te pūnaha pūngao o nāianei. E tohu ana tēnei ka nui ake te atamai me te ngāwari o ngā whatunga hiko o muri mai. I roto i te ipurangi pūngao, i te mea ka piki ake te ōwehenga o ngā kaiwhakamahi tohatoha me ngā rauemi pūngao, me nui ake ngā āheinga whakahaere mō te tuku hiko. I roto i ngā whatunga tohatoha atamai, me pupuri e te whatunga he pūngao tino pumau me te kounga teitei, me te whakauru hototahi i te maha o ngā pūtake pūngao whakahou tohatoha me te aroturuki/whakahaere i ngā āhua mahi whatunga. Ka whakatakotohia e ēnei whakaritenga he tono kaha ki te atamai o ngā taputapu whatunga pūngao, engari ko ngā whakawhiti auau mana tuku iho e pāngia ana e ngā herenga mahi.

Ko te whakawhiti hiko-tiketike he taputapu hiko i hangaia hei huri i te pūngao hiko i waenga i ngā taumata ngaohiko, e mahi ana i roto i te awhe o110 kV ki te 500 kVHe mea nui ēnei whakawhiti hiko i roto i ngā pūnaha tuku hiko, e whakaiti ana i te ngaronga o te hiko i te wā e tuku hiko ana i tawhiti, me te whakarite hoki i te tuku hiko haumaru ki ngā whare, ki ngā pakihi, me ngā ahumahi. Hei tauira, ka whakaputa hiko ngā tipu hiko i ngā ngaohiko teitei, ā, ka whakatikatikahia e ngā whakawhiti hiko tēnei ngaohiko—mā te whakanui ake i te tuku hiko, mā te whakaiti rānei i te ngaohiko mō te kai a te kaiwhakamahi mutunga—kia pai ake ai te whai huatanga me te haumaru.
