| 摘 要： | 覆冰导线在风力作用下产生的舞动会对输电线路造成很大的破坏,严重威胁着输电线路的安全运行,开展特高压输电线路舞动的防治研究非常必要.通过达朗伯原理,建立安装新型防舞装置后覆冰导线的运动方程,比较全面地考虑了功角的作用,并把间隔棒和防舞装置作为线路的集中载荷,得到比较完全的覆冰导线运动的稳定性条件.结合线路具体情况,依据稳定性条件设计出符合要求的新型防舞器参数.该研究成果为中国特高压输电线路的舞动防治提供了技术支撑和理论指导.

| Abstract: | The necessity of research on prevention of ultra high voltage(UHV) transmission line galloping was discussed because wind induced galloping of iced conductors on the transmission line can cause great damage and become serious threat to the safe operation of lines.Based on D'Alembert's principle an equation of motion of iced conductor with a kind of new anti-galloping devices was established,which takes the angle of attack into account comprehensively.In the model the spacer dampers and anti-galloping device... |
