220kV配电装置悬吊式铝管母线的设计探讨

220kV配电装置母线选用悬吊式铝管母线,具有母线穿越功率大,抗震性能好,母线弧垂小等优点,逐步在宁夏地区工程中采用。本文结合小坝220kV变电站220kV配电装置的设计,从管母线电动力、挠度、应力、悬吊式绝缘子串选择等多方面,论述220kV配电装置悬吊式铝管母线选择方法和结果,为今后悬吊式铝管母线的选择提供参考。

Discussion on the design for hanging pipe type bus-bar of 220kV distribution equipment

220kV distribution equipment adopts hanging pipe type bus-bar,which has the following merits: larger through power flow of bus-bar,better shockresistant function and less bus-bar drooping arc. According to the design of 220kV distribution equipment in 220kV Xiaoba Substation,from the electric driving force,flexibility,stress and hanging insulator strings,discusses the selective methods and results of hanging pipe type bus-bar on 220kV distribution equipment,provides the selecting reference for the hanging pipe type bus-bar.
