摘要: 针对输电线路屏蔽环振动频率监测困难的问题,提出一种非接触式振动频率识别方法。以某已建成特高压线路屏蔽环为例,进行振动频率识别,并采用精细化有限元方法对屏蔽环进行模态分析,验证了该方法的可行性。分析表明:屏蔽环振动频率图像识别方法与有限元方法计算频率接近,能使用图像识别方法对输电线路屏蔽环进行振动频率识别。

关键词: 屏蔽环, 振动, 图像识别, 模态分析, 输电线路

Abstract: In order to monitor the vibration frequency of shielding ring of transmission lines, a non-contact vibration frequency identification method is proposed. Taking a shield ring of an ultra-high voltage (UHV) transmission line as an example, the method of image recognition is used to recognize the vibration frequency, and the finite element method is used to verify the feasibility of the proposed method. The analyzing results show that the frequency obtained by two different methods are close, and the image recognition method can be used to identify the vibration frequency of shielding ring of transmission lines.

Key words: shield ring, vibration, image recognition, modal analysis, transmission line
