有限施工面积条件下配电线路杆塔紧凑型接地降阻方法研究

Dianci bileiqi
输配电线路防雷的重点均在于降低杆塔的接地电阻，但配电线路杆塔往往因距离居民生活区较近而缺少一定的接地施工面积，使得常规的杆塔降阻措施的应用受到了一定限制，并存在接地电阻不能达标等问题。首先利用有限元仿真计算软件COMSOL Multiphysics建立了配电线路杆塔桩基自然接地仿真模型，计算分析土壤电阻率、杆塔埋深等因素对桩基冲击散流特性的影响规律；然后针对现有同塔多回配电线路所面临的耐雷性能不佳与接地降阻可供施工面积不足等问题，提出基于柔性接地模块的杆塔紧凑型接地降阻策略 ...

基于改进YOLOv7的多尺度特征提取绝缘子缺陷检测算法

Gaoya dianqi
针对绝缘子图像缺陷尺寸小、背景干扰因素多、难易样本不平衡等问题，提出了一种多尺度融合的YOLOv7（MSF-YOLOv7）算法，并将其应用于输电线路绝缘子的缺陷检测。首先，通过多尺度卷积块注意力模块（multi scale-convolution block attention module，MS-CBAM），深度聚合带有丰富语义信息的特征图，提升网络对不同尺度目标的检测性能；其次，在主干网络利用新开发的全局空间金字塔池化（global spatial pyramid pooling-fast ...
