一种基于电场分布特性的断路器外瓷套绝缘失效诊断方法

Dianci bileiqi
目前断路器在线监测手段无法对断路器外瓷套绝缘失效进行有效的诊断，定期检修无法及时诊断绝缘故障。变电站检修人员在巡视时通过电场测量发现一种电场分布的通用规律，因此，本研究提出一种基于电场分布特性的断路器外瓷套绝缘失效诊断方法。首先分析了断路器合闸状态的机械结构，基于模拟电荷法研究了断路器空间电场的分布特性，提出了电场强度“M”型曲线通用规律并通过仿真及实测验证，然后利用高压实验室对变电站绝缘失效的断路器外瓷套进行加压模拟试验，结合“M”型曲线的特征参数建立特征数据库并诊断断路器绝缘失效类型。研究结果表明 ...

华中地区500 kV架空线路复合绝缘子批量发热诊断分析研究

Dianci bileiqi
近几年来复合绝缘子缺陷、故障问题频发，其中影响最大的就是复合绝缘子芯棒酥朽断裂问题。为进一步研究串型、温升与绝缘子内部缺陷的关联性，文中以华中地区某两条500 kV架空线路57支发热复合绝缘子为研究对象，开展了实验室红外检测、数字X射线检测（DR检测）、剖检等11项综合性试验。结果表明，该批次复合绝缘子存在严重的护套与芯棒粘接不良家族性缺陷，该缺陷是导致绝缘子异常发热的根本原因。同时紧凑型V串绝缘子受力和高场强影响，缺陷率相对I串较高。此外，通过对比分析多项试验所检出的缺陷情况和缺陷位置 ...
