Mechanism Design and Analysis of Suspension Insulator Detection Robot

, 2014
随着社会的发展，激增的工农业和居民用电需求和技术的进步促使电力系统的容量不断增大、额定电压等级也不断提高。与此同时，架空输电线路中的污闪事故也不断增多。尤其是最近美国、加拿大发生的大面积电网停电事故，更给电力系统以深刻的警示，对高压输电线路绝缘子的预防检测愈来愈重视，对绝缘子检测仪器的要求也愈来愈高。电网中由于不良绝缘子造成的线路闪络事故时常发生，已给国民经济造成了巨大的损失。因此，检测高压输电线路的不良绝缘子已成为国内外电力部门十分关注的一个问题。 传统上，绝缘子检测主要是依靠人工登塔进行检测 ...

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 ...
