500kV输电线路新型防舞金具试验

 减振防舞阻尼弹簧相间间隔棒作为一种新型防舞金具,通过弹簧、橡胶和重球系统吸收导线振动时的能量达到防舞的目的。运用导线疲劳振动试验系统,对安装普通和减振防舞阻尼弹簧相间间隔棒的两相六分裂导线进行模拟舞动试验。稳定时对比子导线垂直和水平方向的位移。结果表明,相同条件下安装减振防舞阻尼弹簧相间间隔棒时导线垂直和水平方向的位移都小。由此验证,减振防舞阻尼弹簧相间间隔棒具有较好的防舞效果,是一种非常实用的防舞金具。

Experimental Study of the New Anti-dance Fittings for 500kV Transmission Line

A new kind of anti-dance fittings is composed of vibration-reducing and anti-dance damping spring interphase spacers to absorb the vibration energy of the wire through a spring, rubber and heavy ball system. The wire fatigue vibration test system platform is used to conduct the galloping tests of two phase six bundled wires installed with the ordinary interphase spacer and the vibration-reducing and anti-dance damping spring interphase spacer. The wire's vertical and horizontal displacements are measured against time after the movement becomes stable. It is concluded that the displacement of the wire is smaller when it is installed with the vibration-reducing and anti-dance damping spring interphase spacer under the same conditions and that the vibration-reducing and anti-dance damping spring interphase spacer has a better anti-dance performance and is a very practical anti-dance hardware, which can be applied in the transmission line.
