    220kV ULAWULO LOKULAWULWA KWAVOTI LWEZIGABA EZINTATHU

    I-TRANSFORMER

    Isifinyezo

    220kV uwoyela wezigaba ezintathu ocwiliswe ku-voltage olawula ukulayisha uletha uchungechunge lwezinguquko ezinkulu mayelana nempahla, indlela, kanye nokwakhiwa.Kuwuphawu lokwakhiwa okuhlangene,
    isisindo esiphansi, ukusebenza kahle okuphezulu, ukulahlekelwa okuncane, umsindo ophansi, nokuthembeka kokusebenza.Umkhiqizo unganciphisa ukulahlekelwa okukhulu kugridi nezindleko zokusebenza futhi wandise ukusebenza kahle kwezomnotho okuhlukile.
    Umkhiqizo uhlangabezana namazinga kazwelonke alandelayo: GB1094.1-2013 Iziguquli zamandla Ingxenye 1: Okujwayelekile;I-GB1094.2-2013
    Iziguquli zamandla Ingxenye 2: Ukunyuka kwezinga lokushisa;I-GB1094.3-2003 Iziguquli zamandla Ingxenye 3: Amazinga okushisa, ukuhlolwa kwe-dielectric kanye nokuvunyelwa kwangaphandle emoyeni;GB1094.5-2003 Iziguquli zamandla Ingxenye 5: Amandla okumelana ne-short-circuit;
    I-GB/T6451-2015 Ukucaciswa kanye nezidingo zobuchwepheshe zezigaba ezintathu zokucwilisa amandla kawoyela.
