Zusammenfassung:To improve objectivity and accuracy of large power transformer condition assessment and determine weighing of different related technical indexes, this thesis proposes a combined weighing method of connotative weighing and structural weighing, which makes up for deficiency in single weighing method. Membership function-G1 method is adopted to determine weighing to facilitate application and reduce calculation amount. Establishment of multilevel assessment model realizes multi-level assessment of transformer condition, whose assessment results reflect not only comprehensive transformer condition but also index condition at each level. The thesis exemplifies objectivity and comprehensiveness of the method which creates more scientific and accurate assessment result of transformer condition.
