GIS internal insulation discharge type multispectral feature analysis method and system

The invention provides a GIS internal insulation discharge type multispectral characteristic analysis method and system, and the method comprises the steps: carrying out a sealed gas chamber experiment, filling a gas chamber with SF6 gas, simulating the internal environment of a GIS, carrying out the discharge in different modes, simulating different discharge faults caused by the insulation defect of the GIS, employing a spectrograph, and carrying out the analysis of the multispectral characteristics of the GIS internal insulation discharge type. Collecting and recording the ultraviolet spectrum, the visible spectrum and the infrared spectrum; data mining: carrying out normalization processing on the data, identifying peak value characteristics in the spectral data through a segmentation clustering algorithm, and removing interference on the spectral data caused by discharge duration; and establishing a discharge type identification model by using a convolutional neural network, inputting the collected spect
