本发明涉及一种基于缺陷模式的变电主设备诊断方法和系统。该方法采用基于缺陷模式的设备缺陷诊断方法，通过明确变电主设备的缺陷模式，定义基于检测项目的缺陷判据，定义分析矩阵和缺陷概率综合算法，对缺陷进行定性分析，有效实现变电主设备的缺陷诊断；并通过计算状态量的严重程度，对缺陷进行定量分析，同时也为开展状态评价和风险评估提供数据基础。 The invention relates to a method and a system for diagnosing power transformation main equipment based on a defect mode. According to the method, an equipment defect diagnosis method based on a defect mode is adopted, qualitative analysis is carried out on defects by defining the defect mode of power transformation main equipment, defining defect criteria based on detection items and defining an analysis matrix and a defect probability comprehensive algorithm, and defect diagnosis of the power transformation main equipment is effectively achieved; and by calculating the severity of the state quantity, quantitative analysis is carried out on defects. Meanwhile, a data basis is provided for carrying out state evaluation and risk evaluation.
