Research on health monitoring of high-voltage power transmission tower based on PVDE piezoelectric sensor

针对高压输电塔的健康监测问题,该文设计了一种聚偏氟乙烯薄膜(PVDF)压电传感器,可检测高压输电塔的固有频率,将测得的固有频率与健康时的固有频率对比,分辨出高压输电塔是否受到了损伤。测试结果显示,该PVDF压电传感器表现优良,可以用于实际的信息采集。

In order to solve the problem of health monitoring of high-voltage transmission tower,a PVDE piezoelectric sensor is designed.The sensor can detect the natural frequency of high-voltage transmission tower.By comparing the measured natural frequency with the natural frequency in health,the high-voltage transmission tower damaged or not can be distinguished.Test results show that the PVDF piezoelectric sensor works well,so it can be used for the actual information collection.
