Kōwhiringa Pai mō te Parenga DC Ngaohiko-Teitei — Ngā Paunga Rua i roto i te Mahi me te Pono o te Pana Wehewehe DC

I te tere o te whanaketanga o te pūngao hou, e whakamahia whānuitia ana ngā pūnaha hiko DC ngaohiko teitei (HVDC) i roto i te photovoltaic (PV), te rokiroki pūngao me te kawe tereina. He mea nui te haumaru o tā rātou mahi, nā te mea he uaua te wehenga me te tiaki hapa nā te ahunga o te iahiko pumau o te HVDC me te kore o te whakawhiti kore taiao. Nō reira, he mea nui te whakamahi i ngā taputapu wehenga whai hua, pono hoki.

Hei taputapu tiaki HVDC matua,Pātene Wehewehe DC(Pātene momotu hiko DC) ka wehea ā-tinana ngā ara iahiko, ka tapahia ngā hapa, ā, ka whakarite i te haumaru. He rerekē ki ngā pātene AC, he mea hanga motuhake mō ngā pewa DC uaua ki te tineia, ā, ko tana mahi i raro i te ngaohiko teitei ka whakatau tika i ngā taumata tiaki pūnaha.

E whakamārama ana tēnei tuhinga i ngāPātene Wehewehe DCngā putanga hou o te mahi me te pono, me te tātari i tōna uara matua i roto i te tiakitanga HVDC hei ārahi i te kōwhiringa tono.

Ko ngā āhuatanga HVDC e hiahia ana kia teitei te mahi a te pana wehe, tae atu ki te manawanui ngaohiko teitei me te pehi pewa whai hua. Ka tutuki i te Pana Wehewehe DC ngā putanga rua hei whakatutuki i ēnei hiahia.

I roto i te manawanui ngaohiko teitei, kei roto i te whakatupuranga hou ngā whakahoutanga hanganga me ngā rauemi, e urutau ana ki te 1500VDC me raro iho (me te teitei ake mō ngā kaupapa motuhake). Ko te whakamarumaru kaha teitei me ngā hononga kua arotauhia ka ārai i te pakaru. E ai ki "Ngā Paerewa Motuhake me ngā Whakaritenga Tiwhikete mō ngā Pana Wehewehe DC mō ngā Tono Photovoltaic", ka mahi pūmau ngā pana e tutuki ana i te IEC 60947-3 i te ngaohiko kua whakatauria, me te pikinga pāmahana o te ara iahiko parahi ≤60K.

Mō te mahi pakaru, ka tere te pehi arc-blow peak matatau me te pakaru maha-ira i ngā arc DC (kāore nei he whiti-kore taiao). Hei tauira, ka tutuki i ngā pana raupapa ABB Emax te pakaru haumaru 1500V DC / 100kA, ka karohia ngā hapa.

Ka pakaruhia e ēnei whakahoutanga ngā herenga pana tuku iho, kia pai ai te whakahaere o ngā kaupapa HVDC.

Haunga te mahi, ka whakapai ake te Pātene Wehewehe DC hou i te pono, ka whakatau i te roa o te ora ratonga me ngā take tiaki nui i roto i ngā āhuatanga uaua.

Ka roa ake te ora o ngā hononga pūngao-rahi me te tuku kua arotauhia mō ngā mahi neke atu i te 10,000, ka whakaiti i te tiaki me ngā utu—he mea tino pai mō ngā kaupapa rokiroki pūngao me te hiko nui.

Mā te tiakitanga IP66, ka ātete ki ngā pāmahana tino kino (-40℃ ki te 85℃), te haumākū me te rehu tote, kia mau ai te mahi o waho/ahumahi.

E tutuki ana hoki i ngā paerewa IEC 60947-3 me GB/T 14048.3, e whakapūmau ana i te haumaru me te tutuki i ngā whakaritenga.

Me ngā whanaketanga rua, e whakamahia whānuitia ana te Pātene Wehewehe DC i roto i ngā mara matua o te HVDC: ngā taha DC o te tipu PV (te wehe i te wā tiaki), ngā pūnaha rokiroki pūngao (te wehe i te pūhiko-hurihuri), me ngā pūtake hiko DC o te waka tereina/ahumahi (te tapahi hapa).

3. Pukapuka Ā-ringa Hua mō te Pana Wehewehe DC ABB Emax Series

P1: He aha te rerekētanga matua i waenga i ngā pana wehe DC me AC? A1: Ka whakamahia e ngā pana DC he taputapu tinei pewa motuhake (hei tauira, he pupuhi aukume) mō ngā pewa DC uaua ki te tinei; ka whakawhirinaki ngā pana AC ki te whakawhiti kore pewa AC.

P2: He aha ngā taumata ngaohiko ka taea te urutau ki roto? A2: 1500VDC me raro iho; ko ētahi hua e tautoko ana i ngā taumata teitei ake mō ngā kaupapa motuhake.

P3: Me pēhea te whakarite i te pono i roto i ngā taiao uaua? A3: Ko te tiaki IP66, ko ngā rauemi ātete-waikura me te hanganga kua whakapaitia ka ātete ki ngā āhuatanga tino kino.
