摘要
在特高压直流输电线路工程中,直线塔通常采用导线V型悬垂绝缘子串,由于该金具串形式多样,受力复杂,在选型时往往又存在粗放设计的情况,因此会使工程存在一定的资源浪费情况。文章利用受力平衡原理对直线塔V型悬垂绝缘子串选型的数学模型进行分析,得到V型悬垂绝缘子串选型计算方法,给出计算程序编写流程图,将程序应用于某±800 kV特高压直流输电线路工程中,验证了该方法的正确性和可行性。
In ultra-high voltage(UHV)direct current transmission line projects,conductor V-type suspension insulator strings are typically used on tangent towers.Due to the diverse forms and complex forces on these strings,there is often a situation of extensive design during selection,which results in resource waste.Using the principle of force balance,this paper analyzes the mathematical model of V-type suspension insulator string on tangent towers,obtains the computing method and provides the flow chart for writing the program.The program is used to a±800 kV ultra-high voltage direct current transmission line project,verifying the correctness and feasibility of this method.
