1. Isishwankathelo

I-Voltage ephezulu ye-MV kunye ne-HV Drain Valveyivalvu ekhethekileyo eyenzelwe ngokukodwa ii-transformers zamandla aphezulu (ingakumbi kwiimeko ezifana nee-transformers zaseMelika kunye nee-substations ezihlanganisiweyo kwangaphambili). Umsebenzi wayo ophambili kukukhulula ngokukhuselekileyo uxinzelelo lweoyile kunye negesi oluveliswa ngaphakathi kwi-transformer ngenxa yokusilela kokufakelwa, ubushushu obuphezulu bendawo, okanye ukukhutshwa kwe-arc. Ikwajonga ukuthembeka kokutywina, ukumelana nokugqwala, kunye nokulula kokusebenza. Uyilo lwayo luhambelana nemigangatho yoshishino lwamandla aseMelika (njenge-IEEE C57 series, ANSI/IEEE 386). Iyahambelana neempawu zesakhiwo see-transformers zaseMelika (ezifana neetanki zeoyile ezincinci kunye neenkcukacha ze-flange interface). Licandelo eliphambili lokuqinisekisa ukusebenza ngokukhuselekileyo kwee-transformers.

 2. Fukutyas

Ukunciphisa uxinzelelo ngokuchanekileyo, ukuthintela ukuqhuma koxinzelelo olugqithisileyo

Ukhuseleko oluvaliweyo ngokupheleleyo, akukho kuvuza

Uyilo oluchasene nokukhukuliseka kweoyile kunye noluhlala ixesha elide

Iyahambelana neetransformer zesitayile saseMelika.

3.Isicelos

Isetyenziswa kakhulu kwiitransformer ze-high-voltage zesitayile saseMelika (ezifana nee-substations ze-box-type zaseMelika, ii-modular transformers, ii-substations ezenziwe kwangaphambili), ezifanelekileyo kakhulu kwi:

· 1). Iimeko ezineemfuno eziphezulu zokhuseleko lwezixhobo kwiindawo zokusasazwa kwezixhobo ezidolophini, kwiindawo zoshishino, njl.njl.;

· 2). Iindawo ezingcolisayo ezifana nokufuma okuphezulu, isitshizi setyuwa okanye iipaki zeekhemikhali (zifuna ukukhethwa kwemizimba yeevalvu zokugquma ezichasene nokugqwala);

· 3). Izitishi ezikrelekrele ezifuna ukuhlolwa rhoqo okanye ezingenabantu (kucetyiswa ukuba zibe nomsebenzi wokuphendula ngemiqondiso).
