The utility model discloses an electric energy quality disturbance classification detection device which comprises a sampling unit, a signal conversion unit, a signal synchronization unit, a data processing unit, a display interaction unit and a storage unit. The signal conversion unit is used for converting low voltage and small current into direct current digital signals; the signal synchronization unit is used for providing a starting signal for the sampling unit and performing hysteresis compensation processing on the direct-current digital signal; and the data processing unit is used for performing feature extraction on the direct current digital signal, classifying the power quality disturbance by using a directed acyclic graph support vector machine, outputting a power quality disturbance classification detection result to the display interaction unit for display, and storing the result in the storage unit. The device can improve the accuracy, timeliness and anti-interference capability of power qualit
