摘要
对2008年冰灾后新编制的GB50545—2010《110～750 kV架空输电线路设计规范》需要深入学习理解。介绍了该规范的编制背景,通过与原有相关规范的比较,研究了其主要修改的内容。根据该规范的规定以及差异化设计的精神,对上海地区设计气象条件进行了具体确定。以200 kV两种典型铁塔为例,分析了该规范对线路设计的影响。
The newly compiled GB50545-2010 ＂110～750 kV Overhead Transmission Line Design Code＂ after ice disaster of 2008 needs a thorough and comprehensive study.Its compiling background is introduced,the main modifications of its content are studied through comparison with former codes.According to regulation of the code and the difference-oriented design principle,the code specifies the designing meteorological condition of Shanghai area.Given two 200 kV classic towers as an example,the influence of the new code to line design is analyzed.
