Okuqukethwe

Ukuqalisa

AI-220 KV SubstationIngabe indawo kagesi ephakeme edlalwa yiqhaza elibalulekile ezinhlelweni zokudlulisela kwamandla kwesifunda.

Njengoba amazwe andisa ingqalasizinda yawo yamandla ukuze ahlangane nokukhula kwezimboni, ukuhlanganiswa kwamandla, kanye nokuhlanganiswa kwamandla okuvuselelekayo, okufakwayo kwamandla angama-220 kuya ngokuya kuthunyelwa kumagridi kazwelonke, amakhompiyutha ezimboni, kanye nokuxhumeka kwezindawo.

220 kV Substation

Kuyini indawo engama-220 KV?

AI-220 kilovolt (kv) yokufakwa esikhundleniIsebenza kuma-voltage angu-300,000 volts futhi ngokujwayelekile ingxenye yegridi yokuhambisa i-voltage voltage.

Lokhu kufakazelwe ngokuvamile kwenzelwe:
