The evaluation of equipment group status has some reference value for maintenance strategy optimization and distribution network reliability evaluation. In this paper, the fuzzy evaluation method of variable weight is applied to evaluate the equipment group of power distribution network hierarchically. The importance degree of individual equipment in the evaluation of equipment group is determined by the load size and the importance degree of load borne by the equipment, the network equivalent method is applied to calculate the weight of individual equipment, and the conjoint analysis optimization algorithm is applied to realize dynamic weight variation. A set of transformer winding and casing and a partial 10kV line are taken as examples to verify the effectiveness of the proposed method.
