500 kV同塔双回紧凑型塔

文章叙述了SCZ和SCJ 系列500 kV 同塔双回并架紧凑型塔的结构、特点。通过比较可知:SCZ 系列500kV 紧凑型直线塔比常规鼓型塔塔高降低了29 % ,塔重减轻了27 % ,塔占地面积减少了一半;SCJ 系列500 kV 紧凑型转角塔比常规鼓型转角塔塔高降低了21 % ,塔重减轻了23 % ,铁塔占地面积也减少了30 %;总之,减少了投资,降低了钢耗,提高了耐雷水平。并在真型试验、对比分析的基础上提出了今后新的工作设想。

500 kV Identical Double Circuit Compact Type Tower

The paper illustrates the structures and features of 500 kV double circuit towers of compact type of SCZ and SCJ series.It is known through the comparison that 500 kV compact type suspension towers of SCZ series are 29% lower in height,27% lighter in weight and one half in land occupation than those of the conventional drum type towers;while 500 kV compact type suspension towers of SCJ series are 21% lower in height,23% lighter in weight and 30% less in the land occupation than those of the conventional drum type towers.In general speaking,their investment is reduced with reduction of steel consumption and increase of the lightning resistance level.Also a new assumption for the future work has been put forward based on the test of real model towers with comparison and analysis.
