This paper focuses on reducing the power frequency magnetic field under the multiple-loop lines in the same tower by optimizing the phase sequence arrangements of the lines.
为了减小同塔多回输电线路的工频电磁场,使其达到最低水平,通过相序优化布置的方法,综合考虑输电线路工频磁场空间最大值极小和平均值极小两个指标,计算与比较两种各回导线均垂直布置的同塔多回输电线路不同相序线路下方工频磁场,给出了各层对称的双回导线均逆相序排列,且相邻两层的下层双回的顶部导线与上层双回底部导线相序相同的最优相序布置规律。
The pylon and beam synchronous construction technology does not rigidly adhere to the past main pylon-before-main beam construction method,uses the pylon and beam synchronous con- struction,which has been verified in many cable-stayed bridges.
塔梁同步施工技术不拘泥过去先主塔后主梁的施工方法,采用塔梁同时施工,在多座斜拉桥中得到了验证。
