摘要

本文介绍了239台以乙炔为主要气体的高压设备发生故障时的油溶气分析结果。分析揭示了以乙炔为关键气体的13种类型的断层，这些断层通过溶解气体比率、其浓度和断层列线图的值来区分。对于每种类型的断层，绘制的图形域与列线图不同，允许考虑可能的坐标漂移。介绍了一种基于图形域的故障识别技术。简要描述了故障的类型，并给出了不同调查人员识别故障的例子。对设备诊断数据进行基于Duval三角的比较分析。研究表明，通过不同方法进行的诊断可能彼此存在显著差异，也可能与实际诊断存在显著差异。所提供的结果允许通过溶解气体分析数据提高故障识别的准确性。

Analysis of gas composition in oil-filled faulty equipment with acetylene as the key gas

The article presents results of oil-dissolved gas analysis for 239 units of high-voltage equipment with faults under which acetylene is the key gas. The analysis revealed 13 types of fault with acetylene as the key gas that are differentiated by values of the dissolved gas ratios, their concentrations, and fault nomographs. For each type of fault, graphic domains are plotted that, unlike the nomographs, allow taking into account a possible coordinate drift. A graphic domain based fault identification technique is introduced. The types of fault are briefly described, examples of their identification by different investigators given. Duval Triangle based comparative analysis of the equipment diagnosis data is performed. It is revealed that diagnoses made by different methods may differ significantly both from each other and from actual diagnoses. The results presented allow increasing fault identification accuracy via dissolved gas analysis data.
