I whakarewahia e NGI te utaina tere-teitei 2400V tuatahi o te ao mō te whakamātautau hiko

Papamuri Ahumahi: Te Tomo ki te Wā Ngaohiko Teitei o te Kilovolt

Nā te tere o te whanaketanga o ngā hangarau utu tere o ngā waka hiko, kei te whanake haere ngā papaaho ngaohiko waka mai i ngā hoahoa matua 400V me 800V ki ngā taumata ngaohiko teitei ake. E ai ki te paerewa ā-motu GB/T 20234.1-2023 Conductive Charging Connection Set for Electric Vehicles – Wāhanga 1: Ngā Whakaritenga Whānui, kua whakapikihia te ngaohiko utu DC kua whakatauria ki te 1500V. Ko tēnei tohu nui te whakaurunga mana o ngā waeine hiko ngaohiko teitei—pērā i ngā waeine puranga utu, ngā pūhiko hiko o runga, ngā waeine hiko pokapū raraunga, me ngā kaitahuri rokiroki pūngao—ki te wā o te karaehe kilovolt.

Ngā Wero Whakamātautau: Te Whakamātautau Mana Ngaohiko-Teitei i raro i te Pēhanga e Piki Ana

I te ahu whakamua o te umanga ki te ngaohiko teitei ake me te mana teitei ake, ko ngā ngaohiko whakahaere o ngā kōwae mana matua—pērā i ngā kōwae utu tere DC mō ngā teihana utu EV, ngā PCS rua-aronga ngaohiko teitei, me ngā pūhiko HVDC pokapū raraunga—kei te neke haere mai i te 400V / 800V / 1000V ki te 1200V me te 1500V. Ahakoa ka taea e te ngaohiko teitei ake te whakapai ake i te pai me te whakaiti i ngā mate, ka puta mai hoki he wero nui mō te manatoko me te whakamātautau mahi.

Mō te whakamātautau i ngā waeine mana e mahi ana i runga ake i te 1500V, ko ngā otinga whakamātautau kawenga tuku iho—ko ngā kawenga whakaora me ngā kawenga ātete te nuinga—e whakaatu ana i ngā herenga mārama o te tere urupare hihiri, te tere huri o te iahiko, te tika, me te āheinga whakarerekētanga ngaohiko-tiketike tonu.

Ngā kawenga whakaora

Ko ngā kōwae hiko ngaohiko teitei o ēnei rā e hangai ana ki ngā semiconductors o te whakatupuranga tuatoru pērā i te SiC me te GaN e whakatakoto ana i ngā whakaritenga tino teitei mō te tere urupare hihiri kawenga me te tere hurihanga o te au. Nā ngā herenga āhuahanga ā-roto, he uaua ki ngā kawenga whakaora te whakatauira tika i ngā huringa kawenga tere me te tauwhiro, ā, kāore i te eke ki te tere urupare me te tere hurihanga.

Ngā Kawenga Ātete me ngā Kawenga Hiko Tuku Iho

He matotoru ngā pēke kawenga ātete mana-teitei tuku iho, he uaua ki te whakamatao, ā, kāore i te tino tika te whakahaere. Kāore e taea e rātou te whakatauira i ngā āhuatanga mahi uaua e hiahiatia ana e ngā waeine hiko hou, kāore hoki e taea te whakatutuki i ngā whakaritenga whakamātautau pakari mō te urupare hihiri me te tere whakarere o te iahiko.

Hei tāpiri atu ki tēnā, ko ngā kawenga hiko tuku iho e herea ana e te kaha o te taputapu ki te tu atu ki te ngaohiko, ā, i te nuinga o te wā ka taea te tautoko i te 1200V, nā reira kāore i te pai mō te whakamātautau i ngā kawenga ngaohiko tino teitei.

Ka Whakahohe a NGI i te Whakamātautau Mahi mō ngā Kaihanga Pūrere Hiko Taumata-Pito o te Ao

Whakaritenga Kaihoko

He kaihanga waeine hiko ārahi o te ao a Kiritaki A, me āna hua e kapi ana i ngā waeine utu mahi-teitei, ngā pūnaha whakawhiti pākahiko, me ngā pūnaha rokiroki pūngao, e whakarato ana i ngā otinga ngaio mō te utu, te whakawhiti pākahiko, me ngā tono rokiroki pūngao.

I te wāhanga tōmua o te whanaketanga, i hiahiatia e te kiritaki te whakamātautau i ngā āhuatanga putanga hihiri o ngā kōwae hiko DC, me te tumanako ka tutuki i ngā taputapu kawenga ngā whakaritenga mahi tino pakari.

Otinga NGI: Utaina Hiko Mahi-Teitei 2400V

Hei aro tika ki te whanaketanga o te ngaohiko teitei o te umanga, kua whakaurua e NGI te kawenga hiko DC tere-teitei 2400V / 1600V tuatahi o te ao, he mea hanga ki te ngaohiko tino teitei, he 2400V / 1600V, e tutuki katoa ana i ngā whakaritenga whakamātautau o ngā pūhiko hiko e mahi ana i runga ake i te 1200V.

Te Kapinga Ngaohiko Tino-Teitei me te Kiato Mana Teitei

He tino hototahi te raupapa ngaohiko-tiketike 2400V / 1600V ki te whakamātautau waeine mana 1500V, me te whakarato hoki i te whānuitanga e tika ana mō ngā whakapainga hangarau a meake nei, me te whakarite hoki i te wāhi haumaru mō te whakamātautau.

Me te whakatauranga mana kotahi-wāhanga o te 5kW i roto i te anga 3U, ka tautoko te pūnaha i te mahi whakarara maha-wāhanga, ka taea ai te whakawhānui ngāwari ki ngā tekau, ki ngā rau rānei o ngā kirowati.

Ka eke te kaha o te iahiko mōrahi ki te 2500A, e tutuki katoa ana i ngā whakaritenga whakamātautau iahiko kawenga-katoa mō ngā waeine utu mana-tiketike.

Urupare Hihiri Tino Tere

Mā te tere o te tauhohenga me te tere o te urupare taumata-iti-hēkona, ka taea e te pūnaha te aromatawai tika i ngā tohu mahi matua pērā i te urupare hihiri, te pumau o te koropiko whakahaere, me te whanonga parenga ngaohiko/auau nui.

Te Tika Tino-Teitei me te Hoahoa Maha-Awhe

Hanganga awhe-toru U/I/P/R

Te tika o te ine i te ngaohiko: 0.015% + 0.015% FS

Te tika o te ine i te au: 0.04% + 0.04% FS

Ka tutuki pai i tēnei hoahoa ngā whakaritenga whakamātautau whānui, tino tika hoki puta noa i ngā āhuatanga whakahaere rerekē.
