| Zusammenfassung: | The invention relates to a high-voltage insulation fault diagnosis method based on heterogenous image temperature rise and partial discharge characteristics. The high-voltage insulation fault diagnosis method based on heterogenous image temperature rise and partial discharge characteristics includes the steps: extracting the contour of an infrared image and the contour of an ultraviolet image; performing image registering based on the contour information to obtain the optimal affine transformation parameter; by means of the optimal affine transformation parameter, performing ultraviolet imagetransformation, extracting the ultraviolet spot contour diagram and the ultraviolet gray level image of the ultraviolet image after transformation, and performing fusion of the infrared image and theultraviolet image; and extracting the greatest temperature rise and the partial discharge characteristics from the fused image, and at the same time constructing a fuzzy logical reasoning system to perform external insulation |
