摘　　要：某220 kV变电站因极端天气洪水浸泡,导致110 kV副母管母支架基础不均匀沉降。经与传统处理方式比较,提出可调基础的优化处理方案。工程实施表明,该方案不但比传统处理方式缩短时间,还能减少电气设备的停电次数,理想情况下可以带电纠偏;对可能发生的后续沉降,还能通过调整装置调节处理,毋须再次施工加固。A 220 kV substation was immersed in floods due to extreme weather,resulting in uneven settlement of the foundation of the 110 kV auxiliary main pipe main support.Compared with traditional processing methods,an optimized processing plan with adjustable foundation is proposed.The implementation of the project shows that this plan not only shortens the time compared with traditional treatment methods,but also reduces the number of power outages of electrical equipment.In an ideal condition,it can be corrected with electricity;possible subsequent settlements can also be adjusted and processed through adjustment devices without the need for re-construction reinforcement.
