电力变压器的故障诊断专家系统

A Fault Diagnosis Expert System for Power Transformers

介绍了一种实用的电力变压器故障诊断专家系统，此系统用变压器的故障现象、油中色谱分析结果及电气试验结果作为故障信息，采用三比值法、特征气体法、故障现象、电气试验结果单独或综合诊断电力变压器故障，系统采用正向推理技术，用Ｃ语言设计完成，操作简便，专家知识丰富，适合专业人员使用。

This paper introduces a practical failure diagnosis expert system for power transformers. Using the three-proportional and characteristic gas methods, failure spectra and electrical test results, the system diagnosed power transformer's failure independently or synthetically according to failure phenomena, results of color spectra in oil and the results of electrical test of power transformers. With abundant knowledge of expert, forward reasoning technology and C language program, the system has the characteristics of operating easily and suitable for technicians.
