大吨位瓷绝缘子瓷件强度的统计性方法

Dianci bileiqi
瓷绝缘子在保障电力系统的可靠性和安全性方面发挥着至关重要的作用。然而，由于瓷件的机械强度存在较大分散性，为确保产品机械强度的一致性，设计时要求瓷件的断裂强度保证值高于钢脚和铁帽的断裂强度，从而确保断裂发生在分散性较小的钢脚部位。目前，国内几大绝缘子生产厂家已大幅提升绝缘子的断裂强度，部分企业的平均强度甚至超过额定值的两倍，但瓷件断裂的情况仍时有发生。因此，钢脚、钢帽与瓷件的强度匹配方式对降低瓷绝缘子破坏强度的分散性至关重要。近年来，电瓷行业内围绕瓷绝缘子破坏强度的统计描述方法展开了广泛讨论 ...

基于模态分析的GIS盆式绝缘子带电检测技术

Gaoya dianqi
GIS盆式绝缘子表面污秽和裂纹等缺陷会使得其表面的闪络电压降低，严重危害电力网络的正常运行，因此盆式绝缘子状况检测研究对于保障电网安全运行具有重要意义。基于模态分析法，文中研制了盆式绝缘子状态带电检测系统，对盆式绝缘子表面污秽、裂纹缺陷开展试验研究。结果表明盆式绝缘子污秽缺陷会使得其模态传递函数幅值发生变化，且盆式绝缘子模态特性对于污秽质量的变化敏感；裂纹缺陷会使得盆式绝缘子模态传递函数极值点发生后移；表面污秽与表面裂纹缺陷共同作用下，模态传递函数的高频段2 000~4 000 Hz内幅值变化更剧烈 ...
