摘要
因气体绝缘开关(gas insulated switchgear,GIS)设备具有运行可靠性高的优点,在电网基建工程中被广泛应用,但该设备存在扩建停电时间长、停电范围大等缺点。文章以220 kV变电站中220 kV GIS设备作为扩建对象,分别讨论了整间隔扩建和预留间隔扩建情况下的扩建、检修停电方案。通过对比分析,得出对正常供电系统的影响最小的扩建方案,确定为本期工程备用间隔建设方案。
Due to its high reliability,GIS equipment is widely used in power grid infrastructure projects,but the equipment has some disadvantages,such as long time and large area of power outage for expansion.This paper takes 220 kV GIS equipment in 220 kV substation as the expansion object,and discusses the expansion and maintenance power outage plan in the case of whole interval expansion and reserved interval expansion respectively.Through comparative analysis,the expansion scheme with the least impact on the normal power supply system is obtained,which is determined as the construction scheme of the standby interval in this period.
