摘要
基于近年来500 kV山区紧凑型线路不断出现的风偏、脱冰跳跃、覆冰舞动、V串球头脱出及相间间隔棒安装支架断裂等故障,提出在山区微地形、微气象地段采用差异化设计,通过对500 kV线路紧凑型转换为常规型、常规型转换为紧凑型的研究,实现了同一条线路针对不同地形、不同气象条件的差异化设计,从技术和经济性方面对500 kV线路设计提供了多方案选择的条件,填补500 kV线路设计"相互转换"的空白,通过工程实际应用,消除了朔云线、云吕线等山西省重要输电通道的故障隐患。
In recent years, windage yaw, ice shedding, galloping of iced conductor, V series ball head out and interphase interval rod mounting bracket fracture and other issues occurred in 500 kV mountain type compact transmission lines. This paper uses differential design in microtopography and mierometeorology site of mountain area, through the research of interconversion between 500 kV compact type and 500 kV conventional type transmission line, differential design for different terrain and different meteorological conditions of the same line and a variety of options for the design of 500 kV transmission line in aspects of technology and economics are provided, which fill the gaps in the design of interconversion in 500 kV transmission line. Through the practical application, the design has eliminated the hidden trouble of some important transmission lines, such as shuozhou-yundingshan and yundingshan-lvliang transmission line in Shanxi.
