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 ...

Dianci bileiqi在极端强降雨条件下，输电线路、变电站及换流站中的绝缘子伞裙间距因密集的雨柱而被连接，这一现象会显著改变原有电场分布，造成电场畸变。瓷质绝缘子作为电力系统常见绝缘元件，在长期服役过程中，不仅需承受自身重量，还不断受到风力等外部载荷的作用，这些因素作用下，逐渐导致陶瓷内部绝缘性能的退化，进而形成零值绝缘子。为研究强降雨条件35 kV绝缘子串雷电冲击放电特性，针对输电线路复合绝缘子及U70BP/146D瓷绝缘子串不同零值情况开展雷电冲击放电特性测试。结果表明 ...
