定制传感器监测输电塔整体倾斜的试验分析

Test Analysis of the Sensor Made-to-Order for Monitoring the Whole Incline of Electric Transmission Towers

为了验证一种定制的应变式传感器能用来监测铁塔主材的受力状态,开展了杆件拉力试验和压力试验。试验数据的分析结果显示:传感器输出值和加载值是正相关的,因此这些输出值是可靠的。在输电铁塔的主材处安装这种传感器,一旦传感器的输出值超过主材正常应力范围,并有增大的趋势,则应对该铁塔进行详细检查,以确保其安全运行。

Bar tension tests and pressure tests have been carried out on a special strain gauge sensor,which is made for monitoring the stress state of tower’s main material.Analysis of the test data shows that the output-loaded correlation of the sensor is positive,and thus the sensor output is reliable.Once the output value of the sensor,installed at the location of tower’s main material,is over the normal range of the material’s stress,and even becoming more,the tower should be checked carefully to ensure its operation safety.
