Multi-source information fusion high-voltage switch cabinet fault diagnosis method

The invention discloses a high-voltage switch cabinet fault diagnosis method based on multi-source information fusion. The high-voltage switch cabinet fault diagnosis method specifically comprises the following steps: step 1, collecting characteristic signals of a high-voltage switch cabinet and classifying fault types; step 2, generating a BPA based on a triangular fuzzy number; step 3, fusing a modified D-S evidence theory; according to the invention, state monitoring and fault diagnosis of the high-voltage switch cabinet can be realized. 本发明公开了一种多源信息融合的高压开关柜故障诊断方法，具体包括如下步骤：步骤1，高压开关柜特征信号收集和故障类型分类：步骤2，步骤2，基于三角模糊数的BPA生成：步骤3，修正D-S证据理论的融合：步骤4，设备故障的决策诊断。本发明能够实现对高压开关柜的状态监测与故障诊断。
