Comprehensive assessment of power transformer condition based on the fault tree and the Analytic Hierarchy Process

摘要

Transformers state comprehensive assessment to provide the basis for the repair and maintenance of power transformers. Based on the fault tree analysis (FTA) to find out the impact of the failure of the power transformer factors, and the establishment of the index system to assess the state of the power transformer, application scale analytic hierarchy process assessment model for the establishment of the state of the transformer, and thus the transformer state is divided into five levels. Through the classification of the more conducive to the staff to understand the transformer condition, reasonable arrangements for the maintenance plan. Case analysis to prove, based on the comprehensive assessment of the fault tree and power transformer condition of the Analytic Hierarchy Process method is reasonable and effective.
