摘要/Abstract

摘要：

传统架空导线的风阻系数及电阻损耗较大,在沿海台风区应用该类型导线,不利于线路工程造价的降低及线路可靠性的提高。以国内首条应用节能型低风压导线的输电线路——福建莆田忠田~湄洲110 kV线路工程为依托,通过风洞试验研究节能型中强度全铝合金低风压导线风阻系数的变化规律并确定工程风阻系数取值,结合沿海强风区输电线路的特点,从输送容量、电阻损耗、电气性能、力学及荷载特性、工程投资、经济性评价等方面对节能型低风压导线与铝包钢芯铝绞线、全铝合金导线、铝合金型铝绞线等传统导线进行了系统分析及比较。研究表明,中强度全铝合金低风压导线在节能降阻、减小导线及杆塔风荷载、降低工程投资等方面具有明显优势,在沿海台风区具有良好的应用前景。此外,根据低风压导线特殊的结构型式,研制出配套的接续金具。

Abstract:

The wind drag coefficient and resistance loss of conventional overhead conductor is large, the application of this type of conductor in coastal typhoon area is not conducive to reduce the investment and improve the reliability of transmission line. Based on Zhongtian-Meizhou 110 kV transmission line project in Fujian province which is the first time to apply the drag reduced conductor in domestic transmission line, the change rule of wind resistance coefficient is obtained through wind tunnel test. At the same time, according to the characteristics of the transmission line in coastal strong wind area, comparing with the conventional conductors such as Aluminum conductor aluminum-cald steel reinforced, all aluminum alloy conductor and aluminum conductor alloy reinforced, the energy-saving drag reduced conductor is systematically analyzed from the aspects of transmission capacity, resistance loss, electrical performance, mechanical and load characteristics, project investment, economic evaluation, etc. The research shows that the drag reduced conductor has obvious advantages in energy saving, reduction of wind load on conductor and tower, reduction of investment, it has a good application prospect in the coastal typhoon area. Besides, the matching fittings which are suitable to the special structure of the drag reduced conductor are developed.

Key words: Transmission line, drag reduced conductor, energy-saving conductor, typhoon area, drag coefficient
