绝缘子发热是运作中较为常见的缺陷,尤其是盘型悬式瓷绝缘子串持续发热,往往会在较短的时间内发生贯通性击穿,进而引起瓷绝缘子爆裂故障。针对该现象,以某220 kV变电站盘型悬式瓷绝缘子发热、爆裂故障展开归一化研究,通过等值盐密、绝缘电阻、耐压试验等技术手段,发现发热的瓷件均为低(零)值绝缘子,并在宏观检查中发现发热和爆裂的绝缘子,钢帽和盘型瓷件连接处(即颈部位置)断面均存在裂纹,且钢帽内水泥胶合剂存在水分子侵入疏松痕迹,考虑内嵌瓷件受内外圈水泥胶合剂的内挤外压力作用 ...

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 ...
