| 摘 要： | 为解决电力输电线路雷电绕击与反击事故难以辨别的问题,提出在架空输电线路的绝缘子串悬挂金具处和杆塔横担下方竖杆处安装Rogowski型电流传感器,并根据2个传感器输出电流的极性关系判别绝缘闪络类型。以单片机为核心开发了输电线路雷击监测系统,线路监测终端通过无线接力传输模式与变电站监控主站传输数据;在输电线路遭受雷击时,发送雷击类型、杆塔位置等信息,自动形成雷击数据库。系统软件分为终端部分软件和变电站主控制室系统软件,终端软件采用C语言编程。该监测系统已在110kV线投入运行。

| Abstract: | To detect the lightning strike of overhead transmission lines,it is proposed to install the Rogowski coil sensors at the grounded metal terminal of insulator string and below the cross arm of the vertical tower.The polarity relation between their output currents is measured to identify the shielding failure from the back flashover.A singlechip-based lightning strike monitoring system of overhead transmission lines is developed.When the transmission lines suffer lightning strikes,its monitoring terminals the... |
