| description | The invention relates to a defect detection method and equipment for gas-insulated metal-enclosed equipment, and the method comprises the following steps: S1, collecting sound signals of the gas-insulated metal-enclosed equipment, and carrying out the de-noising processing of different noises through employing corresponding methods; s2, extracting a feature value from the de-noised sound signal, wherein the feature value is one or a combination of a time domain feature value, a frequency domain feature value, a harmonic feature value and a voice feature value; and S3, comparing the characteristic value obtained in the step S2 with a characteristic value of a pre-established diagnosis model of the gas-insulated metal-enclosed equipment, and judging the defect classification of the gas-insulated metal-enclosed equipment. Compared with the prior art, the method has the advantages of automatic defect detection, accurate detection result, convenience and the like.
