| 摘 要： | 为研究外力撞击高压输电杆塔对电塔振动情况的影响,利用傅里叶变换与小波分析的方法,针对实际情况中的电塔受铁质、木质材料不同程度的撞击产生的振动信号进行特征分析,得出了一种通过振动信号的主要特征频率对应的不同幅值来判断电塔振动类型的方法。将该方法应用于实际高压电塔振动监控系统中,测试表明系统能够有效判断电塔的振动类型。

| Abstract: | In order to research on the vibration type of high-voltage transmission tower struck by external forces,this paper,using the method of Fourier transform and wavelet analysis,according to the real situation the tower struck by the iron or wood materials produce different levels of vibration signals for feature analysis,obtained a method which by the vibration signal’ s main features frequency corresponding to the different amplitude to determine the vibration type of the tower.The method is applied to actual high-voltage tower vibration monitoring system,the tests show that the system effectively determine the vibration type of the tower. |
