| Abstract: | Aiming at the acetylene content out of limit problem of convertor transformer during aUHV DC transmissionand transformation project debugging phase, analyzes deeply available detecting technology, puts forward a combined detecting technology based on oil chromatographydetecting method, high frequency partial discharge, ultra high frequency partial discharge andultrasonic partial discharge detecting method. The application result showsthat this combineddetecting technology can effectively and accurately detect the number, types and locations of the faultin convertor transformer. |
