二进制图像分析的变压器油气相色谱分析故障诊断方法

Transformer Fault Diagnosis Method of Gas Hromatographic Analysis Using Computer Image Analysis

针对三比值法在变压器油气相色谱分析中的局限性,采用雷达图来直观的表示油中溶解气体的相对含量,建立典型的故障类型雷达图模型。利用MATLAB将待测数据雷达图图像与典型的故障类型雷达图像做二进制图像相似度计算,依此给出某些故障的发生概率,提供潜在故障出现的可能性,避免三比值法的结果单一性。

According to the limitations of Three ratio method in Gas chromatographic analysis of transformer,uses radar chart to show the relative content of gases dissolved in oil intuitively,sets up the typical radar chart modeles of fault type.Calculates the similarity of binary images of the radar chartes prepared to be tested and typical modeles of fault type,to export the probability of some failures,provids the possibility of potential failures,avoids the unicity of results by the three ratio method.
