The invention discloses a method for diagnosing mechanical states of a distribution switch on the basis of empirical mode decomposition (EMD) sample entropy and fuzzy c-means clustering (FCM). The method comprises the following steps that a piezoelectric accelerometer is mounted near to a main shaft...
