A Survey on Oil Chromatogram Analysis for Fault Diagnosis of Transformers

对变压器故障诊断的油色谱分析方法进行了综述,首先分析了电力变压器的常见故障,给出了变压器运行状态的主要测试与监测手段,然后着重介绍了一种变压器故障的综合监测判断方法—油色谱分析法。其中重点讨论了基于专家系统的故障诊断方法和基于神经网络的故障诊断方法。最后,进一步探讨了基于油色谱分析进行变压器故障诊断的前景,以及需要解决的问题。

A survey on oil chromatogram analysis for fault diagnosis of transformers is presented.First, the frequently encountered transformer faults are analyzed, and the usually adopted testing and monitoring methods for the running status of transformers are given.Then, emphasis is put on the oil chromatogram analysis for fault diagnosis methods of transformers, in which the expert system and neural network based methods are particularly discussed. Finally,the development trend of the oil chromatogram analysis based fault diagnosis of transformers and some open problems are pointed out.
