输电塔台风振动响应在线监测的新型传感器设计

摘要

输电线路塔线体系具有杆塔高、跨距大、柔性强等特点,对极端天气环境激励比较敏感.设计开发了用于输电塔实时在线振动监测的新型加速度传感器节点,使用该传感器对受2016年4号台风“妮妲”影响下的特高压输电塔进行了实时在线监测,获取了台风环境下输电塔的振动响应测试数据.实测结果不仅表明了这种新型传感器性能稳定、数据可靠,同时还验证了传感器的准确性.%Because transmission line tower-line system has high tower,large span,strong flexibility and so on,so it is sensitive to extreme weather conditions.A new type of acceleration sensor node for real-time on-line vibration monitoring of transmission tower is designed and developed.This sensor was used to monitor the UHV transmission tower in the typhoon" Nida" in 2016,and the vibration response test data of the transmission tower in the typhoon environment was obtained.The results of test not only show that this new type of sensor is stable and reliable,but also verifies the accuracy of the sensor.
