Gaoya dianqi高压输电线路绝缘子串中的劣化件会威胁电网安全。为了研究劣化瓷绝缘子的红外发热特性，设置了一系列实验，研究了劣化绝缘子的电阻、沿串位置和环境相对湿度对红外检测的影响。并对含有两片劣化绝缘子的绝缘子串进行了附加实验，以研究了正常绝缘子和低值绝缘子之间不同的发热现象。利用有限元分析仿真进一步分析了红外图像中钢帽的发热机理。实验和仿真结果表明：劣化绝缘子的温升与阻值呈非线性关系，当电阻为30 MΩ时温升最大；绝缘子串两端的劣化易被检测；相对湿度过高可能会导致误检；正常绝缘子的发热区域是钢帽的下部 ...

Dianci bileiqi氧化锌避雷器对于保障电网主设备安全具有重要意义，然而随着设备规模的不断增大而运维资源增长相对缓慢，及时发现已劣化的避雷器面临挑战。为此文中研究了基于状态量优化的避雷器健康状态评估方法，为应对设备规模大幅增加条件下开展运维检修策略优化提供参考。首先分析了氧化锌避雷器的故障特征，发现通过泄漏电流或红外热成像能有效检出电阻片受潮或劣化缺陷；针对电阻片受潮和劣化等典型缺陷提出以巡视和带电检测为主开展状态评估的优化状态量；接着建立了基于优化状态量的避雷器健康状态评估模型，通过不同状态量分段扣分与单一扣分相结合 ...
