摘要
介绍了安哥拉Lomaum水电站~Biopio220 kV开关站220 kV双回路送电线路和Biopio^Benguela Sul变电站220 kV单回路送电线路的工程概况。论述了为满足IEC60826标准计算荷载、并适应高海拔山区36.1 m/s超大风速等多种不利因素的联合作用所开展的超限铁塔设计研究过程,并在确保220 kV输变电工程安全可靠的前提下,采取优化措施尽可能地节省工程造价。
An introduction was made on the 220kV double-loop transmission line between Lomaum Hydropower Project and Biopio Substation, and on the 220kV single-loop transmission line between Biopio Substation and Ben- guela Sul Substation. This project has unfavorable conditions such as locating in high-altitude mountain area with extra-high wind velocity up to 36.1m/s. In order to satisfy the specifications of IEC60826 for calculating loads, ex- tra-limit steel tower was studied and designed. Optimization was also conducted to minimize the construction cost under the premise of safety and reliability of proiect.
