某变电站220kV双层出线构架设计优化

为解决变电站占地面积逐渐减小和出线规模不断增加之间的矛盾,不少变电站开始采用双层出线门型构架。文章依托某500kV变电站内的220kV双层出线构架设计实例,分析比较了不同结构形式的双层出线构架的特点,为今后其他类似工程提供参考。

In order to solve the contradiction between the reduction in the area of substations and the increasing scale of outlets,many substations have begun to adopt double outlet framework.Based on a design example of a 220kV double outlet framework in a 500kV substation,this paper analyzes and compares the characteristics of the double outlet framework with different structures,whichprovides a reference for other similar projects in the future.
