Open publisher page 1 citations

Abstract

UHV transformer's structure is different from 500 kV transformer',which adopts neutral point voltage regulating method,and adds the independent voltage regulating transformer.The characteristic of UHV transformer structure and variety instance of second protection configuration are introduced,and the configuration and characteristic on primary protection of main body transformer and voltage regulating transformer and compensating transformer,and back-up protection of main body transformer,and non-electric-parameter protection are analyzed.
