摘　　要：介绍了一种在覆盖集理论框架上集成模糊推理的诊断方法，在此基础上建立了应用于电力变压器故障诊断的实用模型。由于该模型实现了模糊推理与符号推理的结合，能够较好地解决故障诊断过程中遇到的模糊性问题，并有助于实现对故障的综合诊断，所以具有较高的诊断准确性和实用性。A diagnostic method integrated covering theory and fuzzy reasoning is introduced in this paper. Based on it, a practical model applied for the fault diagnosis of power transformer is constructed. With this model, the integration of fuzzy reasoning and symbolic reasoning could be realized. The fuzzy question of fault diagnosis could be solved effectively, and the synthetic diagnosis of fault could be acquired simultaneously.Thus,satisfactory accuracy and well practicality could be achieved.
