1. Isishwankathelo

I-Voltage ephezulu ye-MV kunye ne-HV Drain Valveyivalvu ekhethekileyo eyenzelwe ngokukodwa iitransformer zamandla aphezulu (ingakumbi kwiimeko ezifana neetransformer zaseMelika kunye nee-substations ezihlanganisiweyo kwangaphambili). Umsebenzi wayo ophambili kukukhulula ngokukhuselekileyo uxinzelelo lweoyile kunye negesi oluveliswa ngaphakathi kwitransformer 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 seetransformer zaseMelika (ezifana neetanki zeoyile ezincinci kunye neenkcukacha ze-flange interface). Licandelo eliphambili lokuqinisekisa ukusebenza ngokukhuselekileyo kweetransformer.

 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).
