摘　　要：输电线路绝缘子长期工作在高电磁场强度的野外环境中,加之大气污染、小动物攀爬、雷害、低温覆冰等客观因素,很容易发生闪络,又由于其分布范围广,致使工作人员很难及时确定闪络绝缘子的位置从而消除事故隐患。针对这一问题,对基于导线取能的绝缘子闪络远程定位系统进行了设计研制,研究结果表明能够迅速、精确地确定闪络绝缘子的位置,且具有供电电源稳定、超低功耗等优点。Flashovers often occur in the isolators of transmission lines working in the field environment of high electromagnet field intensity for a long time due to air pollution, climbing of small animals, thunder damage, low temperature, icing and other objective factors. As they are widely distributed, operators find it difficult to timely locate flashover insulators to eliminate hidden faults. In view of the above situation, this paper presents a design of a remote insulator flashover positioning system based on power supply from the transmission line. The result shows that the system can accurately determine the location of flashover insulators and has such advantages as steady power supply and ultra-low power consumption. , with a steady power supply and low power consumption, successfully achieves a fast and accurate flashover insulator positioning.
