Isingeniso
A400kvisiteshi esincaneumhlahlandlelakuyingxenye ebalulekile yenethiwekhi yokudluliswa kwamandla kagesi aphezulu, iqinisekisa ukudluliselwa kahle kukagesi usuka ezimbonini zokuphehla ugesi uye kumanethiwekhi okusabalalisa.
Lesi sihloko sihlola i-izingxenye, imisebenzi, izinhlobo, izinhlelo zokusebenza, namathrendi wesikhathi esizayoyeziteshi ezingaphansi ezingama-400kV.
Yini i-400kV Substation?
AIsiteshi esincane esingu-400kVyakhelwe ukwenyusa noma ukwehlisa amazinga kagesi kagesi, iqaphe ukusebenza kokuhanjiswa, kanye nokuqinisekisa ukuphepha kwamasistimu kagesi.
Kungani 400kV?
- Ukudluliswa kwamandla amabanga amade okusebenzayongokulahleka kwamandla okuncane.
- Iqinisekisa ukuqina kwegridingokuphatha ukusatshalaliswa kwamandla amakhulu.
- Isekela isidingo samandla ezimboni nasemadolobheningamanethiwekhi aphezulu.
Izingxenye Ezibalulekile Zesiteshi Esingaphansi esingu-400kV
Isiteshi esincane ngasinye siqukethe amathuluzi anamandla kagesi aphezulu kanye nezinhlelo zokulawula.
| Isakhi | Umsebenzi |
|---|---|
| I-Power Transformer | I-voltage yezinyathelo phezulu/ephansi ukuze idluliselwe noma isabalalise. |
| I-circuit breaker | Ivikela igridi ngokuphazamisa imisinga yamaphutha. |
| Amabhasi | Famba ugesi ngaphakathi kwesiteshi esincane. |
| Izinqamuli | Hlukanisa amathuluzi ngesikhathi sokulungiswa. |
| Amabhange e-Capacitor | Thuthukisa isici samandla nokuzinza kwe-voltage. |
| Surge Ababoshwa | Vikela ngokumelene nombani nokunyuka kwamandla kagesi. |
| Isistimu ye-SCADA | Inika amandla ukuqapha okukude nokulawula kwesiteshi esincane. |
Izinhlobo zeziteshi ezingaphansi kuka-400kV
Ngokusekelwe ohlotsheni lwe-insulation kanye nendawo, iziteshi ezincane ze-400kV zihlukaniswa ngokuthi:
Isiteshi esincane esifakwe umoya (AIS)
✔ Isebenzisa okokufaka umoya ovulekile ezintweni zikagesi.
✔ Ibiza izindleko kodwa idingaisikhala esengeziwe.
✔ Isetshenziswa kakhulu ezindaweni zasemakhaya nasezindaweni zasemadolobheni.
Isiteshi esincane esifakwe igesi (GIS)
✔ Compact design ngeUkufakwa kwegesi kwe-SF6.
✔ Ifaneleizindawo zasemadolobheninendawo elinganiselwe.
✔ Izindleko zokufaka eziphakeme kodwaukugcinwa okuphansi.
Iziteshi ezingaphansi kweHybrid
✔ Inhlanganisela yobuchwepheshe be-AIS ne-GIS.
✔ Ibhalansiizindleko kanye nokusebenza kahle kwendawo.
Izicelo zeziteshi ezincane ezingama-400kV
Iziteshi ezingaphansi ezingu-400kVisetshenziswa kabanzi ezimbonini nasezindaweni ezahlukene.
| Isicelo | Leírás |
|---|---|
| Izitshalo zamandla | Ixhuma ugesi kusuka eziteshini zokuphehla ugesi kuya kugridi. |
| Izindawo zezimboni | Ihlinzeka ngamandla anamandla kagesi ezimbonini zensimbi, izindawo zokuhluza uwoyela, nezimboni. |
| Umphakeli Kagesi Wasemadolobheni | Iqinisekisa amandla athembekile emadolobheni nasezindaweni zezohwebo. |
| Ugesi Wesitimela | Inikeza amandla kuizitimela ezinesivinini esikhulukanye nezinhlelo ze-metro. |
| Ukuhlanganiswa Kwezamandla Avuselelekayo | Isekelaamapulazi omoya kanye nezitshalo zelangaukudluliswa kwamandla ahlanzekile. |
Ukubaluleka kweziteshi ezingaphansi ezingu-400kV
Iziteshi ezincane ezingu-400kV zibalulekile kwingqalasizinda yesimanje yamandla:
Ukuthuthukisa Ukuzinza Kwegridi
- Igwema ukuphela kukagesi kanye nokuguquguquka.
Ukusekela Amandla Avuselelekayo
- Ihlanganisa amapulazi elanga nawomoya kugridi.
Ukunciphisa Ukulahleka Kwamandla
- Amandla kagesi aphezulu anciphisa ukulahleka kokumelana namabanga amade.
I-Powering Industrial and Commercial Zones
- Ibalulekile ezimbonini, izikhungo zedatha, nezindawo zasemadolobheni.
Okucatshangelwayo Okubalulekile Ku-400kV Substation Design
Uma uhlela aIsiteshi esincane esingu-400kV, onjiniyela bagxile kulokhu:
✔Izinhlelo Zokuphepha Nokuvikela- Ukucindezelwa komlilo, ukutholwa kwamaphutha, nokubeka phansi.
✔Ukuhambisana Kwegridi– Ihlangabezana nemithetho kazwelonke yokudlulisela.
✔Izici Zemvelo- Ukulawulwa komsindo kanye nokufakwa kwe-eco-friendly.
✔Ukwandiswa Kwekusasa- Idizayini ye-modular yescalability.
