基于判据融合的异步电动机定子绕组匝间短路诊断OA

To solve the interference problem of other common abnormal operating conditions in the diagnosis of the stator winding inter-turn short-circuit fault,a stator winding inter-turn short-circuit fault diagnosis scheme based on criterion fusion for asynchronous motors is proposed.First,considering the causal relationship between fault features,fusion criteria with current features as the main feature and voltage features as the auxiliary feature are proposed.Next,these fusion criteria are used to diagnose the stator winding inter-turn short-circuit fault and fault phase.Last,the effectiveness of the scheme is verified through simulation experiments.
