摘要
输电线路的风偏闪络是影响线路安全运行的主要问题之一,由于闪络后重合闸成功率低,一旦发生风偏事故,将严重影响电力系统供电可靠性。基于此,本文介绍架空输电线路风偏放电发生的原因及特点,总结目前常见的各项防风偏技术,并对比分析各项技术的优缺点。
The flashover accident caused by windage yaw on transmission line is one of the main problemsthat influence the safe operation of transmission line. Due to the low success rate of reclosing after flash-over, once the accidents caused by windage yaw occur, the reliability of power supply system will be seri-ously affected. In this paper, causes and characteristics of windage yaw discharge in overhead transmissionline were introduced, and common anti-windage yaw technologies were listed and summarized. The advantag-es and disadvantages of these techniques were also analyzed and compared.
