Oil immersed paper bushing is one of the main parts in the transformers, its insulation condition is related to the safety and stability of the operation of transformer. However, the evaluation methods at present only consider single indicator index of only apply subjective or objective weigh method to evaluate the insulation states of oil immersed paper bushing. Therefore, it is necessary to study the insulation state evaluation method of oil immersed paper bushings with multi-dimensional electrical characteristic parameters based on comprehensive weigh method. This paper studies the insulation state evaluation method of oil immersed paper bushings with multi-dimensional electrical characteristic parameters based on comprehensive weigh method. The conclusions are as follows. First, the hierarchical relationship for oil immersed paper bushing considering 7 indicator indexes is constructed. Second, the insulation states of normal, attention, abnormal and faulted are classified. And the judgement model based on the comprehensive weigh assignment for oil immersed paper bushing is established. At last, five bushings of normal, suspended potential fault, corona discharge fault, damped oil and damped paper fault are scored by this model, verifying the validity of this model.
