摘要
针对陕西电网220kV周洋线玻璃绝缘子串因环境湿度和污秽改变引起的闪络事故,根据目前线路的运行状况,对不同组合方式的玻璃绝缘子串在实验室进行了模拟试验,寻找出了提高线路玻璃绝缘子串工频闪络电压的最佳组合方式。
In view of the flashover of glass insulator strings on 220 kV Zhouyang transmission line in Shaanxi Power Grid caused by changing in condition of humidity and pollution, combining with the operation status of the transmission line, the simulation experiments on glass insulator strings in diversity combination modes have been completed in the lab. Finally, the optimum combination mode to improve the power flashover voltage of glass insulator strings on transmission line is found out.
