1. Isifinyezo

I-High Voltage MV & HV Drain Valveiyivalvu ekhethekile eyenzelwe ngqo ama-transformer anamandla aphezulu (ikakhulukazi ezimweni ezifana nama-transformer aseMelika kanye neziteshi ezincane ezihlanganiswe ngaphambilini). Umsebenzi wayo oyinhloko ukukhulula ngokuphephile ingcindezi kawoyela negesi ekhiqizwa ngaphakathi kwe-transformer ngenxa yokwehluleka kokufakwa kokushisa, ukushisa ngokweqile kwendawo, noma ukukhishwa kwe-arc. Iphinde icabangele ukuthembeka kokuvala, ukumelana nokugqwala, kanye nokulula kokusebenza. Umklamo wayo uhambisana nezindinganiso zemboni yamandla yaseMelika (njenge-IEEE C57 series, ANSI/IEEE 386). Iyahambisana nezici zesakhiwo sama-transformer aseMelika (njengezinqolobane zikawoyela ezincane kanye nemininingwane ye-flange interface). Iyingxenye ebalulekile yokuqinisekisa ukusebenza okuphephile kwama-transformer.

 2. Fukudlas

Ukukhululeka kwengcindezi okunembile, okuvimbela ukuqhuma kwengcindezi ngokweqile

Ukuvikelwa okuvalwe ngokuphelele, akukho ukuvuza

Umklamo olwa nokuguguleka kwamafutha kanye nokuphila isikhathi eside

Iyahambisana nama-transformer esitayela saseMelika.

3.Isicelos

Isetshenziswa kakhulu kuma-transformer ane-voltage ephezulu yesitayela saseMelika (njengeziteshi ezincane ze-box-type zaseMelika, ama-transformer e-modular, iziteshi ezincane ezilungiselelwe kusengaphambili), afaneleka kakhulu ku:

· 1). Izimo ezinezidingo eziphezulu zokuphepha kwemishini kumanethiwekhi okusabalalisa asedolobheni, amapaki ezimboni, njll.;

· 2). Izindawo ezigqwalisayo njengomswakama ophezulu, isifutho sikasawoti noma izindawo zamakhemikhali (kudinga ukukhethwa kwemizimba yamavalvu okumboza okulwa nokugqwala);

· 3). Iziteshi ezincane ezihlakaniphile ezidinga ukuhlolwa njalo noma ezingenabantu (kunconywa ukuthi zibe nomsebenzi wokuphendula isignali).
