1) high-frequency vibration of low amplitude
高频低幅抖振动
1.
it is proved through theoretical calculations that longitudinal stretching deformation of the pipe bus-bar due to thermal expansion-shrinkage make a long-term bending stress on the top of post insulator,especially when strong wind subjected to the tubular bus,causing a high-frequency vibration of low amplitude and applied on the post insulator,is the main reason caused the fault of insulator.
通过理论计算证明因热胀冷缩管母线沿轴线伸缩变形对支柱绝缘子上端产生长期弯曲作用力,特别是在风力较大时,管母线受到了风力和由风力产生的高频低幅抖振动加在支柱绝缘子上,是造成绝缘子折断的主要原因。
2) low frequency and great amplitude vibration
高幅低频振动
3) dither
[英]['dɪðə(r)] [美]['dɪðɚ]
高频振动;抖动器
4) RF instability
