摘要

通过对安装新型铅减震器的220 kV断路器振动台试验

分析了新型铅减震器的减震效果。试验结果表明:新型铅减震器不仅可以降低断路器顶部的加速度和位移

使底部瓷套管最大应变减少53%以上

而且输入地震动越强其减震效果越明显。此外

这种减震器还可为断路器提供一定的初始刚度。

Abstract

To investigate the damping effect of new type lead dampers

a shaking table test of the breakers with a new type lead damper is carried out.The results of the test show that the lead dampers are well functioning

limiting the relative displacement and absolute acceleration at the top of bushing.There is above reduction of 53% in the maximum strain of bottom porcelain pipe and the stronger the input ground motion

the larger the reduction will be.Moreover

the lead dampers can provide a definite initial stiffness to the breakers.
