摘要
对500 kV输电线路直线塔采用中相V串或采用中相Ⅰ串的情况,通过在空气间隙、塔头结构、塔重、投资等方面进行比较,得出采用中相V串的优点,进而可使直线塔采用中相V串在实际工程中推广运用。
Middle-phase ＂V＂ insulator string and middle-phase ＂I＂ insulator string in intermediate Tower for 500kV transmission line are compared based on air gap, tower head structure, tower weight, investment and other aspects. Finally, the ＂V＂ insulator string is recommended, which is superior to the other method in economic efficiency and practicability.
