瓷盘型悬式绝缘子串劣化状态自动检测装置研究

Dianci bileiqi
为提高高压输电线路瓷质绝缘子串劣化或低/零值带电检测的准确性，研制了可用于无人机搭载的自动可变间隙火花放电检测装置。首先结合声-光-电检测实现了绝缘子分布电压的自动和准确测量。其次在实验室搭建了间隙放电试验平台，试验确定了球形间隙放电电压与间隙距离的对应关系，据此整定了可变火花间隙测量装置的间隙距离。最后建立了绝缘子串及检测装置等效模型，利用场路结合法研究了检测装置介入对检测结果的影响。研究结果表明，可变间隙距离的火花放电检测装置对绝缘子串原始电场影响小，高精度检测有助于准确地判断绝缘子片劣化程度 ...

基于联合老化试验的GIS隔离开关绝缘子气隙缺陷劣化过程研究

Gaoya dianqi
气体绝缘金属封闭开关设备（GIS）绝缘件内部缺陷引起的放电击穿故障会造成设备非计划停运，且GIS设备故障检修周期长、影响范围大，严重威胁设备和电网的运行安全。目前，对于GIS设备绝缘件应力集中、弱电场区域微小气隙等部分潜伏缺陷，现有试验方法检测有效性受限，其长期运行中的缺陷劣化规律尚不清晰，制约了GIS绝缘件质量提升。文中基于一起GIS隔离开关绝缘子局放缺陷，提出了GIS设备绝缘件的温度、机械—电场同步老化、强电场老化试验方法，探索内部缺陷发展规律。首先将绝缘子装入GIS隔离开关样机 ...
