Ukufakwa kwe-400kv kudlala indima ebaluleke kakhulu ekudluliseleni ugesi ophakeme wamandla aphesheya kwamabanga amakhulu.
Ukuqonda umqondo oyisisekelo
AUkufakwa kwe-400kvIsebenza kuma-voltage ama-volt ama-volts angama-400,000 futhi isebenza njengesixhumi phakathi kwemithombo yesizukulwane - enjenge-thermal, izitshalo zamandla enuzi, noma amanethiwekhi aphansi aphansi.
- Isinyathelo seVoltage noma Step-Down sisebenzisa ama-Transformers amakhulu
- Ukuhlukaniswa nokuvikelwa ngokusebenzisa ama-Breaker Breakers and Drowsnector
- Ukuqapha kanye nokulawula ngohlelo oluphambili lweScada nezinhlelo zokuvikela
- Ukuqinisekisa ukutholwa kwephutha futhi kunciphise isikhathi sokuphumula
Ngokwehla phansi kusuka ekukhiqizeni ama-voltages noma wehla ukuze udluliselwe ukudlulisela, ukunxusa kusiza ukunciphisa ukulahleka kokuhambisa futhi kusekela ukuqina kwegridi.
Izicelo ze-400kv
Lezi zinto eziphakeme eziphakeme zithunyelwa ezinhlotsheni ezahlukahlukene zamasu, kufaka phakathi:
- Amanethiwekhi Okuhambisa Amandla Kazwelonke Nawesifunda
- Amaphoyinti we-Grid Interconnectionphakathi kwezinsiza ezahlukahlukene noma amazwe
- Ama-Hub Amandla Avuselelekayonjengamapulazi amancane noma amapulazi omoya amakhulu
- Amaqoqo ezimboniedinga izinto ezinkulu zamandla
- Ukufakwa kwamadolobhaNgamadolobha ama-mega noma izikhungo zabantu abaningi
Izitayela Zemakethe Nezimboni
Ngokusetshenziswa kwamandla komhlaba wonke kuvezwe ukukhulisa ngokuqinile, isidingo sengqalasizinda yokudlulisela okuqinile njengokufakwa kwezinombolo ezingama-400kv. I-International Energy Agency (IEA), Ukutshalwa kwezimali ezinhlelweni zokudlulisela kulindeleke ukuthi kudlule ama- $ 300 billion ngonyaka ngo-2030. Okwamanje, ezomnotho ezifufusa ngokushesha zithuthukisa amakhono azo wegridi ukuhlanganisa amandla avuselelekayo futhi anciphise ukuncika kumafutha e-fossil.
Wikipediana-Iee xploreIzindatshana zigqamisa isidingo esikhulayo sezinto ezi-smart, ezenzakalelayo kanye namawele edijithali ezindaweni eziphakeme zamandla aphezulu. Abisa,Nokia Energy, futhiSchneider Electricbatshala imali kakhulu emisebenzini emihle ehlobene nokuvikelwa kwedijithali, i-GIS (igesi ebekiwe yegesi), kanye nokuqapha isimo.
Ukucaciswa kobuchwepheshe (okujwayelekile)
| Ipharameter | Thanda |
|---|---|
| Amandla kagesi | 400 kv |
| Imvamisa ekalwe | 50/60 Hz |
| Ukucushwa kwesistimu | Double Busbar / Busbar Single Busbar |
| Umthamo we-transformer | Kufika ku-1000 MVA |
| Uhlobo lweBusbar | I-AIS (AIS ETHUNYELWE) noma GIS |
| Izinga lokufakwa | I-1050 KV BIL (Ileveli eyisisekelo yokususa) |
| Uhlelo lokulawula | Ukudluliselwa kwe-Scada + Ukuvikelwa |
| Izinhlobo ze-switchchear | Abaphula umjikelezo, ama-isolators |
Ihluke kanjani kusuka ezingeni eliphansi le-voltage
Qhathanisa ne-132kV noma i-220KV, ukufakwa okungu-400kV:
- Kudinga okuningiUkufakwa okuqinilena-Ukukhishwa OkukhuluNgenxa yama-voltages aphezulu
- Sebenzisaabakhulu abababiza kakhulu futhi ababizayokanye ne-switchgear
- -NanaIzivumelwano zokuphepha eziqinilefuthi kube yinkimbinkimbiUkuvikelwa Kokuvikelwa
- Ngokuvamile ingxenye yeUkuhanjiswa Kwamandla Bulk, hhayi ukusatshalaliswa
- Kudinga ukuthuthukaAmasistimu wokuqapha nokulawulaNgenxa yesilinganiso samandla aphathwa ngesandla
Umhlahlandlela Wokuthenga: Yini okufanele uyicabangele
Lapho uhlela noma ukuthola indawo engu-400kv, cabanga ngokulandelayo:
- Isikali sephrojekthi: Ingabe ukuxhumeka, ukuhambisa, noma ukusatshalaliswa ngobuningi?
- Ukutholakala kwesikhala: Khetha phakathi kwe-AIS (ngokufuna ukufunwa) noma i-GIS (compact kodwa ebizayo)
- Izimo zezemvelo: Umswakama, ukuphakama, kanye nomsebenzi wokuzamazama komhlaba kungathonya ukwakheka
- Ukulayisha ukubikezela: Umthamo we-transform kufanele uvumele ukukhula okuzayo
- Ukwesekwa komthengisi: Qinisekisa ukuthi i-OEMS ihlinzeka ngezinsizakalo zesikhathi eside nezingxenye ezisele
Uthiphu: Hlala ukhetha imishini ethobelaneIEC 60076,Iee C37, nezinye izindinganiso zomhlaba wonke.

Imibuzo ebuzwa njalo (i-FAQ)
Usayizi uncike ekwakhekeni (ais vs. gis).
Kusuka kunjiniyela ukuyothola, kungathatha izinyanga eziyi-18 kuye kwezingama-36 kuye ngezilinganiso, ukuvunyelwa okulawulwayo, kanye nobuchwepheshe obusetshenzisiwe.
Yebo, ilungele amandla ahlanganisayo emoyeni omkhulu noma amapulazi elanga futhi ayijoyine kuUmhlahlandlela weGridingempumelelo.
Ekuphetheni, indawo engu-400kV ihlala iyitshe legumbi lohlelo lwanamuhla lokuhambisa ugesi. Umhlahlandlela WokusabalalisaKwenze kubaluleke kakhulu kuma-grids alungele ukukusiza.
