Abstract：The shift principle and locking logic of MR tap switch in ultra high voltage (UHV) converter transformer is introduced in this paper. In view of a converter transformer tap switch inconsistent fault, this paper deeply analyzes the causes of the fault, analyzes and discusses the exposed problems, and puts forward the scheme of uploading the tap switch oil chamber temperature to the monitoring background and adding early warning and historical data query. It provides a reference for the follow-up design and operation maintenance of converter transformer tap switch.
Key words： tap switch    inconsistent    temperature    early warning
