摘　　要：通过对不同海拔下500 kV单、双回路线路工频电压、操作和雷电过电压下绝缘子片数的计算,得出在海拔2 000 m以下和2 000～3 000 m悬垂、耐张和跳线串的绝缘子片数,该计算结果已在广西电力工业勘察设计研究院设计的多条西南地区高海拔500 kV线路应用,线路运行情况良好。The article gives numbers of suspension insulators, strain insulators and jumper insulators with altitude of below 2000m and of 2000-3000m based on calculation on insulator number of 500kV single loop and double circuits under power frequency voltage, switching overvoltage and lightning overvohage. The calculation results have been applied for 500kV line in the southwest region at high altitude designed by GXED. Operation conditions of line are excellent.
