摘要(Abstract)：
结合500 kV瓯海变技改工程,针对跨三档管母高层导线更换时停电时间短、作业范围窄等难点,在理论计算的基础上,提出了更换导线的技术方案,详细介绍了高层导线的拆除与安装过程,通过实践验证了技术方案的可行性,保证了更换导线施工的安全和质量。
Based on the 500 kV technical renovation project of Ouhai Substation,this paper presents a technical scheme for high line replacement based on theoretical calculation to deal with the difficulties of short-time outage,narrow operating range etc.for replacement of high line crossing three tubular busbar groups.It describes the processes of the removal and installation of the high line.The scheme proves to be feasible after practice and ensures replacement safety and quality.
