摘要
柔性光伏支架是一种大跨度多连跨结构,该结构为在两端固定点之间张拉预应力钢丝绳,固定点采用刚性结构及外侧斜拉钢绞线提供支撑反力。云南省寻甸县1.97 MW光伏农业扶贫项目部分采用了柔性支架,经5年使用证明该支架系统具有跨度大且跨度范围灵活可调的优势。
The flexible photovoltaic support is a large-span multi-span structure,the prestressed steel wire rope between the two ends of the fixed point is stretched,and the fixed point adopts the rigid structure and the lateral oblique tension steel strand to provide support reaction.The flexible support was used in the 1.97 MW photovoltaic agricultural poverty alleviation project in Xundian County,Yunnan Province.After 5 years of use,it was proved that the support system had the advantages of large-span and flexible adjustable span range.
