500kV变电站超规模扩建工程设计要点

Design Points for Over-scale Expansion Project in 500kV Substation

500kV上党变电站经多次扩建后,已突破原有规模,需破围墙征地扩建。扩建施工过程中,全站站用变电系统改造、500kV悬挂管母高度不一致及220kV双层出线间隔安全距离校验等问题相继暴露。为此,提出相应解决方案,以满足工程需要。

After several expansions,the 500 kV Shangdang substation had broken through the original plan and needs to break the wall to expand the land.During the construction,the problems of transformation of substation system,inconsistency of 500 kV suspension pipe and busbar height,safety distance check of double outlet spacing and other issues were exposed.Corresponding solutions were proposed to meet the engineering needs.
