±500kV直流输电线路悬垂绝缘子串组装方式研究

Assemble Mode Research of Suspension Insulator String in ±500kV DC Transmission Line

V串直线塔的塔重,走廊宽度,风偏开方量,房屋拆迁量,树木砍伐量都小于I串直线塔,且相同串长条件下绝缘优于I型串,房屋拆迁量肯定会有较明显的下降,且部分路径的选择和优化也相对灵活。综上因素,500kV直流输电线路推荐悬垂绝缘子串采用V型串布置。

Technical and economic guidelines of V strings better than I strings, ± 500kV DC transmission line overhanging insulator strings recommended by V strings arrangement.
