摘　　要：提出的一种基于频域阻抗谐振模型的电缆绝缘缺陷识别技术可填补当前破坏性试验的空缺,促进缺陷位置的查找并评估不同缺陷点的严重程度,对开展电缆状态检修有重要意义。基于此,主要从该方法的原理、特点出发,以绝缘老化为例,论证该方法的有效性。This paper proposes a cable insulation defect identification technology based on frequency-domain impedance resonance model,which can fill the gap in current destructive tests,promote the search of defect positions,and evaluate the severity of different defect points.Based on this,mainly from the principle of the method,structural characteristics,the effectiveness of the method is demonstrated by taking insulation aging as an example.
