摘要
钢管塔在特高压工程中的推广应用对钢管塔的可靠性与经济性提出了新的要求。通过分析比较钢管塔与角钢塔的塔材组成,并结合钢管塔的结构特点,提出了通过降低联接件比重实现进一步提高特高压钢管塔经济性的方法。详细分析了目前特高压钢管塔锻造法兰的应用情况,提出锻造法兰精细化设计的新方法,并结合超/特高压同塔4回钢管塔的设计进行了各种方法的可行性和经济性分析。研究表明:在特高压钢管塔设计中,通过应用强度级差与布置优化、结合锻造法兰进行钢管选材等综合措施,最大程度的降低锻造法兰的比重,能够进一步提高特高压钢管塔的经济性。
The popularization of the steel tubular tower in UHV projects has raised new requirements for the tower reliability and economics.By comparing the materials for steel tubular towers and those for angle steel towers and considering the structural characteristics of the steel tube tower,a method for improving the economics of the UHV steel tube tower by reducing the joints is advanced.The application of the forging flange in UHV steel tubular towers is analyzed in detail and a new method for forging flange fine designing is developed.In addition,combined with the design of the EHV/UHV quadruple-circuit steel tubular tower,the feasibility and economics of the related methods are studied.The research shows that in UHV steel tubular tower designing,the proportion of forging flanges can be minimized through several ways,such as strength classification,distribution optimization and material selection.All these can further improve the economics of the UHV steel tubular towers.
