Gaoya dianqi电网设备绝缘材料在生产、运输、施工、现场运行等过程中容易产生缺陷，这严重影响了电网的安全运行。为实现对绝缘材料缺陷的无损检测，文中提出了基于支持向量机（SVM）的太赫兹二维成像方法。制备了聚乙烯（PE）、聚氯乙烯（PVC）和硅橡胶3种带缺陷的典型电力绝缘材料平板样品进行测试，得到缺陷识别准确率的不低于92.3%。在成像方面，与传统的单一特征参数成像方法相比，SVM成像方法对缺陷区域与非缺陷区域具有更好的区分度，边缘过渡区域明显变窄，成像质量较高。

, 2013 自然界的一类生物材料比如骨头、牙齿和贝壳等在长期的演化历史中获得了非常令人瞩目的力学特性,缺陷不敏感就是其中一种。目前弹性结构中的缺陷不敏感现象已经得到了相当多的研究与讨论,但是与时间相关的粘弹性系统的缺陷不敏感特性还鲜有报道,而对于粘弹性性质明显的生物材料,这方面的研究又尤为重要。本文致力于研究一个含有与裂纹的受拉伸粘弹性条带的缺陷不敏感特性,分别基于Griffith模型与Dugdale模型给出了粘弹性条带缺陷不敏感宽度的解析表达 ...

Gaoya dianqi基于无人机航拍的电力巡检成为目前绝缘子缺陷检测方法的主流，但当遇到图像特征不够明显或干扰特征较多等问题时，绝缘子缺陷识别困难，检测精度不高。由此，提出了一种基于改进YOLOv5s的绝缘子缺陷检测方法。首先，重新设计卷积模块，然后将CA注意力机制与其相融合，并且在主干网络加入注意力机制与颈部网络的特征图进行多尺度特征融合，抑制复杂环境下的干扰特征，专注缺陷特征提取；其次，对空间金字塔池化结构（SPPF）进行改进，扩大感受野，减少被模型过滤掉的有用信息；接着，将Transformer与C3模块中的残差结构 ...
