Unconventional Installation and On-Site Partial Discharge Test of Ultra-High Voltage Convertor Transformer

doi:10.11930/j.issn.1004-9649.2013.11.22.3

Abstract

Abstract: Due to the very limited period for installation of low-end convertor transformer in Jinping converter station, which is delayed by difficult transportation condition, unconventional installation techniques had to be adopted. Based on the successful commissioning experience of Jinping converter station, the paper introduces the method of on-site partial discharge test under the unconventional installation condition, and the analyzing and handling methods of abnormal discharge in the test. This partial discharge testing method not only well solves the possible discharge problems caused by unconventional installation techniques, but also significantly improves the testing efficiency and shortens the testing period, which will provide a useful reference for partial discharge testing of UHV converter transformers.

Key words: UHV convertor transformer, partial discharge, on-site test, unconventional installation
