[0039] Example: for a medium voltage circuit breaker in the common type of fault categories, with reference to Figure 3-6 As shown in a medium voltage circuit breaker intelligent diagnostic method based on CNN-QPSO-SVM, comprising the steps of:
[0040] S1: an acceleration sensor vibration acceleration parameter recording circuit breaker / off process, the sampling frequency is 10kHz. An acceleration sensor mounted on the circuit breaker housing, for collecting the vertical vibration signals, a total of 7 sets of vibration signals collected data, comprising: a normal state; tripping the closing electromagnet blocked; spindle plug; 4 principal axle blockage fault types . Fault Type and number as shown in Table 1.
