Isingeniso ekuhlolweni kwe-220 KV
A220 kvukubusisaisizinda sikagesi esiphakeme esisetshenziselwa i-Ukudluliselwa kanye nokusatshalaliswa kwamandla kagesi ezingeni lamandla kagesi ama-kilovolts angama-220. Ukulethwa okusebenzayo, okuthembekile, nokuphephile kukagesingaphesheya kwezindawo ezinkulu.
Izicelo nokubaluleka
I-220 KV efakiwe ibalulekile ku:
- Amagridi Amandla kazwelonke, ikakhulukazi emazweni anengqalasizinda enkulu.
- Izindawo zezimboniedinga imithwalo yamandla ephezulu.
- Izikhungo zasemadolobheniLapho ukufunwa kukagesi kuphakeme ngokungaguquki.
- Izitshalo zamandla avuselelekayo, ikakhulukazi amapulazi elanga kanye nomoya axhunywe kwigridi ephezulu ye-voltage.
Lezi zinto ziqinisekisaUmthethonqubo we-Voltage, Iphutha Ukuhlukaniswa, kanye nokulethwa kwamandla okuphephile, ukusekela ukuqhubeka kokusebenza kwezimboni nezinsizakalo.
Izitayela Zemakethe Nezimboni
Ngokuya kwe-I-International Energy Agency (IEA)nedatha evelaI-IEEMA (I-Electrical Electrical and Electronics Aclererers 'Association), isidingo sokufakwa kwezimali okuphezulu kwamandla kagesi afana nama-220 kV akhula ngenxa:
- Okwandayo ukuhlanganiswa kwamandla okuvuselelekayo.
- Ukunwetshwa kwama-grids ahlakaniphile.
- Ukuthuthuka kwamadolobha kanye nokukhula kwezimboni ezifundeni ezithuthukayo.
Ngo-2024, ukutshalwa kwezimali emhlabeni jikelele kwingqalasizinda yokudlulisela edlula ama- $ 300 billion, ngezingane ezingama-220 ze-KV zifaka isandla kakhulu ekuqineni kwesifunda kanye nokulinganisa umthwalo.

I-AIS vs GIS ku-220 KV Petrations
Kunezinhlobo ezimbili ezivamile zezingane ezingama-220 KV:
- I-AIS (indawo efakwe umoya):
Isebenzisa umoya njengendlela yokufaka phakathi. - I-GIS (I-PAS-insud insud):
SebenzisaIgesi ye-sf6ukufakwa.
Umehluko kusuka ekutholeni okuphansi kwe-voltage
| Ubuso | I-220 KV Substation | I-132 KV / 66 KV Substation |
|---|---|---|
| Ileveli ye-Voltage | Amandla aphezulu aphezulu | Voltage ephezulu |
| Umthamo we-transformer | -Phakeme | Okuphakathi |
| Isikhundla segridi | Izinga Lokuhambisa | Izinga lokusabalalisa |
| Khokhisa | -Phezulu | Okuphakathi |
| Umaka wonyawo enhlabathini | Okukhulu / Compact (GIS) | -Ncanyana |
Umhlahlandlela wokukhetha kanye neseluleko sokuthenga
Lapho ukhetha indawo engu-220 KV noma izingxenye zawo, cabanga:
- Umthwalo wesidingo: Khetha umthamo osuselwa ku-Peak kanye nokubikezela komthwalo wesikhathi esizayo.
- Ukutholakala kwesikhala: Sebenzisa i-GIS lapho umhlaba ulinganiselwe khona.
- Izimo zezemvelo: Uthuli, umswakama, umsebenzi wokuzamazama komhlaba ungahlehlisa umklamo.
- Ezenzakalelayo nokuqapha: Ukufakwa kwamanani kwanamuhla kufanele kuxhase i-scada kanye nokulawulwa okusekwe e-Iot.
- Ukuthobela: Qinisekisa amazinga afanaIEC 62271,Iee C37, kanti amakhodi wokusebenza endawo ahlangatshezwane nawo.

Ukufakwa esikhundleni sama-220 KV kuxhuma imigqa yokuhambisa i-high
Ukufakwa esikhundleni kwe-GIS Gcina isikhala, kuthembeke kakhulu ezindaweni ezinokhahlo, futhi kudinga ukugcinwa okuncane kunezinhlelo ze-AIS.
I-220 KV isebenza endaweni ephakemeizixazululo ze-voltage, isingatha umthwalo omnyama, futhi imvamisa isetshenziswa engxenyeni yokudlulisela yegridi, kuyilapho i-132 kV isetshenziswa kakhulu ekudluliseleni noma ekusatshalalisweni.
