Dianci bileiqi介绍了极端天气下某变电站多个避雷器底座断裂缺陷的发现和处理过程，检查到断裂痕迹均为新断面且个别内壁有裂纹。根据气象信息和运行记录，初步判断避雷器底座断裂的直接原因是瞬时大风。将避雷器底座送检，进行了性能试验，包括绝缘子孔隙性试验、弯曲负荷耐受试验和弯曲负荷破坏试验等。通过机械性能试验验证了故障原因的初判。文末总结了缺陷处理经验，提出了应对极端天气下突发情况的对策和措施。

Zhendong Ceshi yu Zhenduan针对振动作用下发电机绕组绝缘断裂损伤机理与偏心故障影响机制尚未明确的问题，提出考虑静态偏心故障的绕组绝缘损伤分析方法。首先，建立理论模型，对偏心前后的绕组电磁力与绝缘断裂情况进行解析；其次，构建有限元分析模型并进行电磁场分析，验证偏心前后的电磁力分布、幅值及频率变化；然后，进行结构场仿真，揭示绝缘应力分布与裂纹扩展情况；最后，通过实验来验证理论模型与有限元分析结果。结果表明：在正常情况下，各绕组所受电磁力基本相同；发生偏心故障后，气隙减小（增大）处绕组电磁力增大（减小 ...
