摘要
500 kV双回路直线塔主要采用三层横担、导线垂直排列的"鼓型"或"伞型"铁塔,其串型一般采用"6I"或"6V"型的单一串型,采用I、V混合型串的双回路直线塔较少。本文针对典型500 kV双回路直线塔可能采用的各种串型组合方式进行了详尽的对比分析和优化设计,得出了各种串型组合型式的优劣点以及一般情况下的优选串型组合方式,为500 kV双回输电线路杆塔设计提供了参考和借鉴。
The Umbrella-shaped or Drum-shaped Tower is the main type of 500 kV Double-circuit Straight Tower. and its Insulator String Combination is always ＂61＂ or ＂6V＂ , but Double-circuit Straight Tower of I-V-Mixed String is infrequent.Various kinds of Insulator String Combination for typical 500 kV Double-circuit Straight Tower were dicussed in this paper, thus the relative merits of different Insulator String Combination and the commendatory Combination of general condition was proposed,which is aim to provide reference for the design of 500 kV Double- circuit Straight Tower.
