Study On Transformer Condition-based Maintenance Information Management System

The dissertation points out that efficiently and scientifically applying transformer condition information is the basis for the transformer maintenance in case online detecting devices are not prevalent. Then, the dissertation systematically analyzes the information acquired in transformer precaution tests and reaches its classification and characteristics needed for evaluating the transformer conditions. In order to avoid the negative influences by the "true or false" rule, the Five Grades Condition Evaluation Method is proposed to make maintenance periods. Furthermore, the information fusion method is used to carry out condition evaluation. With Delphi and SQL Server 2000 database, the transformer information management system has been set up and with Microsoft IIS, the system can be published on internet. Supported by its operation, the system can completely take on the condition information management and provides substantial boosts for transformer condition maintenance under the real conditions.
