Ngā Mea Matua mō te Whakapai Ahumahi: Ngā Otinga Ahumahi-motuhake e 6 a ngā Whakawhiti Ngaohiko Waenga/Teitei a JZP

I tēnei wā o te tere o te whakawhiti hiko ā-umanga me te pūngao, kua noho ngā whakawhiti hiko waenga/teitei (MV/HV) hei pou tuara mō ngā pūnaha hiko ā-umanga. Hei kaiārahi o te ao i roto i ngā otinga hiko, kua hangaia e JZP he huinga whakawhiti hiko MV/HV kua whakaritea kia aro atu ki ngā hiahia ahurei o ngā rāngai ahumahi kanorau. E tūhuratia ana e tēnei tuhinga ngā tono ahumahi matua e ono e tukuna ana e ngā whakawhiti hiko JZP he mahi whakawhiti, e tautokona ana e ngā māramatanga hangarau me ngā rangahau take o te ao tūturu.

 

1. Te Hanga Atamai me te Aunoatanga

 

Wero: Ko ngā wheketere o ēnei rā e whakawhirinaki ana ki ngā mīhini e whakahaerehia ana e te tino tika me ngā pūnaha e whakahohea ana e te IoT, e hiahia ana kia pumau te ngaohiko me te iti o te ngaronga hiko.

 

Otinga JZP:

 

Mā ngā whakawhiti hiko ritenga (hei tauira, 110kV/6.3kV) me te ngaronga kawenga

 

Whakawhiti Momo-MarokeMā te whakamahi i te whakamarumaru kapia epoxy ka whakakore i ngā tūponotanga ahi i roto i ngā taiao tairongo puehu pēnei i te hanga haurua-ira.

 

Ka mau tonu te mahi a ngā pūnaha whakahaere wera matatau i ngā tautuhinga pāmahana teitei (tae atu ki te +40°C).

 

Akoranga Take: I whakaitihia e tētahi wheketere motuka Tiamana ngā utu pūngao mā te 18% whai muri i te whakatinanatanga o ngā whakawhiti hiko momo-maroke 10MVA a JZP, i arotauhia mō te whakahaere i te whakapōturitanga oro.

 

2. Te Whakaurunga Pūngao Whakahou

 

Wero: Me whakamahi ngā whakawhiti hiko pakari mō ngā pāmu hiko pūngao rā me ngā tāhū hau hei whakapiki i te hiko DC/AC iti-ngaohiko ki ngā taumata hototahi ki te whatunga hiko.

 

Otinga JZP:

 

Ka taea e ngā whakawhiti whatunga 110kV/31.5MVA me te whakamarumaru hau SF6 te tu atu ki ngā āhuatanga kino o waho, ā, ka whakarite kia pono i roto i ngā whakaurunga koraha, takutai rānei.

 

Mā ngā hoahoa ārai-waikura (ngā ārai maitai kore waikura 316L) ka roa ake te ora i roto i ngā taiao makuku, tote rānei.

 

Whakaurunga maeneene ki ngā pūwhakawhiti atamai mō te whakahaere ngaohiko hihiri.

 

Akoranga Take: I whakamahia e tētahi pāmu hiko pūngao rā 500MW i Texas ngā whakawhiti hiko 33kV/11kV a JZP, ā, i eke ki te 99.2% te whakatauranga whai huatanga me te MTBF 25-tau.

 

3. Te Tūhuratanga Hinu me te Hau

 

Wero: E hiahia ana ngā papaaho takutai moana me ngā papa keri tawhiti ki ngā pūnaha hiko ātete-pahūtanga, iti hoki te tiaki.

 

Otinga JZP:

 

Ārai pahūtanga Whakawhiti Marokee tutuki ana ngā paerewa ATEX/IECEx mō ngā rohe morearea (Akomanga I, Wāhanga 1).

 

Mā te ātete teitei ki te ara iahiko poto (40kA/1s) me te ātete ki te wiri ka mau te manawanui ki ngā rohe rū whenua.

 

Mā te aroturuki mamao mā roto i ngā pūoko IoT ka taea te tiaki matapae, ka whakaitihia te wā kore mahi mā te 30%.

 

Akoranga Take: I te Moana-a-Kiwa, ko te 31.5MVA a JZP Whakawhiti Hinu-Rukuhiangā pēhipereki raro moana e whakakahangia ana e s mō ngā tau e 5, kāore he rahunga.

 

4. Ngā Pokapū Raraunga me te Waea

 

Wero: Ko te wā whakatā tata kore e hiahiatia ana, me te iti rawa hoki o te whakapōturitanga oro mō ngā mahi 24/7.

 

Otinga JZP:

 

Ka whakaitihia e ngā whakawhiti haruru tino iti (

 

Mā ngā hoahoa modular ka taea te whakawhiti wera i ngā wāhanga mō te wā mahi 24-hāora.

 

E tutuki ana te hinu ester taiao i ngā paerewa haumaru ahi UL 1411 mō ngā hanganga nui.

 

Akoranga Take: I whakamahia e tētahi pokapū raraunga tauine nui i Virginia ngā whakawhiti hiko 10kV/400V a JZP, ā, i eke ki te 99.999% te pono.

 

5. Te Keri me te Ahumahi Taumaha

 

Wero: Me whakamahi i ngā whakawhiti hiko pakari, ngāwari hoki hei ārai i te puehu, i ngā hau pahū, me ngā kawenga hurihuri i roto i ngā maina.

 

Otinga JZP:

 

Ko ngā whakawhiti hiko ātete puehu kua whakataurangatia IP55 me ngā takai hiri ka ātete ki ngā poke hau.

 

Mā te whānui o te whakahaere ngaohiko (±10%) ka taea te whakauru i ngā āhuatanga whatunga kore pumau i ngā wāhi maina tawhiti.

 

Ka tautoko te kaha uta nui (150% mō ngā haora e 2) i ngā taputapu mana-nui ā-wā pēnei i ngā kuru.

 

Akoranga Take: I whakaitihia e tētahi maina parahi i Chile te wā kore mahi mā te 40% mā te whakamahi i ngā whakawhiti hiko ātete-pahū 2500kVA a JZP.

 

6. Ngā Hanganga Tāone me ngā Tāone Atamai​

 

Wero: Me whakamahi ngā tāone nui kiato i ngā whakawhiti hiko kiato, penapena-pūngao mō ngā rama tiriti me te utu hiko EV.

 

Otinga JZP:

 

Ka penapenahia e ngā whakawhiti hiko kiato e mau ana ki ngā papa (hei tauira, 100kVA) he 40% te wāhi ki te whakaritea ki ngā waeine tuku iho.

 

Ka tautokohia e te whakahaere ngaohiko hihiri ngā teihana utu tere mō ngā EV (tae atu ki te 150kW).

 

Mā ngā tātaritanga atamai mā ngā tūāpapa kapua ka taea te taurite kawenga wā-tūturu.

 

Akoranga Take: I roto i te kaupapa Smart City o Dubai, i taea e ngā whakawhiti hiko 11kV/400V a JZP te whakakaha i te 500+ ngā pūwāhi utu EV me te 98% te whai huatanga.

 

He aha i tū motuhake ai a JZP

Te Oranga Tonu: Tae atu ki te 98.5% te whai huatanga, ā, ka whakaitihia e ngā rauemi hangarua te tapuwae waro.

 

Whakaritenga: Ngā otinga kua whakaritea mō te ngaohiko (6.3kV–110kV), te whakamatao (ONAN/OFWF), me te aukati (4%–10%).

 

Whakamutunga

 

Kua hangaia ngā whakawhiti hiko MV/HV a JZP hei akiaki i te whakahoutanga ahumahi, me te whakakotahi i te hangarau matatau me te urutau motuhake ki te ahumahi. Mai i ngā wheketere atamai ki ngā pokapū hiko o tāwāhi, ka tautuhia anō e ēnei otinga te whai huatanga me te pono o te mahi. Mō ngā pakihi e whai ana ki te whakarite i ā rātou hanganga hiko mō te heke mai, ehara i te mea he kōwhiringa noa te mahi tahi me JZP—he mea nui rautaki.
