Embodiment Construction
[0028] The clustering analysis method of the present invention is described in detail below in conjunction with accompanying drawing and specific example:
[0029] figure 2 The analysis flow chart of the grid-based partial discharge cluster analysis method is described in . In the figure, the cluster analysis starts from the data set input, goes through a series of processing, and finally outputs the cluster results. The implementation principle of the algorithm is as follows:
[0030] Dataset input. By extracting the waveform feature quantity of partial discharge signal, it is used as the input of cluster analysis. through as figure 1 The hardware system shown starts from the sensor receiving the coupled magnetic field information, then extracts the useful information through the down-frequency of the envelope circuit, adopts ADC sampling with a sampling rate of 250M, and uses the programmable gate array to extract various waveform features, such as: amplitude, Character...
