Abstract
A method for evaluating a degassing effect of a cross-linked polyethylene cable, includes: acquiring a cable sample to be detected; heating the cable sample to be detected; under a darkroom condition, acquiring at least one light spot image of said transparent cable sample under irradiation of a monochromatic laser light source; extracting light intensity data of the at least one light spot image in a preset light spot image range; normalizing the light intensity data, and obtaining the maximum value and an average value of normalized light intensity coefficients of said transparent cable sample in a preset thickness range of the insulating layer; calculating a degassing uniformity coefficient according to the maximum value and the average value; and obtaining an evaluation result of the degassing effect of the cross-linked polyethylene cable according to the maximum value, the average value, and the degassing uniformity coefficient.
