超特高压环氧绝缘件超声检测技术及典型缺陷声学回波特征分析

Dianci bileiqi
超特高压环氧绝缘件内部缺陷的可靠检测对于保障电力设备安全可靠运行具有重要意义。文中提出基于超声脉冲反射法实现超高压环氧绝缘件内部气孔、气隙、密度不均等缺陷的有效检出。论文基于声场仿真技术分析多时空尺度下超声波在环氧复合材料内的传播规律，探寻影响环氧复合材料内部缺陷检测灵敏度的关键因素，掌握不同缺陷直径、尺寸、深度下超声回波信号的特征。为验证理论分析有效性，搭建了超声检测试验平台并对特高压盆式绝缘子典型缺陷试样进行了相关的检测试验 ...

一起GIS避雷器异响分析及处理

Dianci bileiqi
介绍了一起220kV GIS避雷器放电缺陷，该避雷器运行时存在异响，经带电检测判断该缺陷为危急缺陷， 立即停电处理，避免了事故发生。经解体检查发现该避雷器安装时动触头严重偏心，动静触头接触不良，逐渐发展为放电缺陷。该案例为GIS设备的安装、巡视、带电检测等具有重要指导意义。

基于模型压缩与知识蒸馏的绝缘子自爆缺陷轻量化实时检测网络

Gaoya dianqi
针对目前绝缘子缺陷检测网络架构复杂、推理计算量大导致占用大量的储存空间、检测效率低下的问题，设计出一种绝缘子自爆缺陷轻量化实时检测网络（insulator defects net，IDNet）。首先，通过空间尺度变换的方法将YOLOv4-tiny基础网络中用于小目标检测任务的26像素×26像素的YOLOhead进行删除，降低网络复杂程度，提升检测速度；然后，根据预设的剪枝比例阈值进行卷积层通道剪枝来实现模型压缩，以减小网络权重，进一步提升网络检测速度；最后 ...
