输电线路在线监测力学传感器的设计及应用
Design and Application of Online Monitoring Mechanical Sensor for Power Transmission Line
基于力学传感器精度、强度的要求,设计了输电线路覆冰在线监测力学传感器。通过有限元分析其应变、应力,对传感器进行结构优化,提高其抗弯矩的强度。对传感器进行信号处理,将传感器的物理信号变换为数据采集、控制过程的电信号,从而完成对覆冰导线重力的检测。该传感器已在紫拉线直流400 kV输电线路安装运行。
Based on the precision and strength requirements, mechanical sensor was designed for icing online monitoring. The strain and stress of mechanical sensor were analyzed through the finite elements in order to optimize its structure and improve its anti-bending strength. Then, with the signal processing, the physical signal of sensor was transformed into the electric signal of data acquisition and control process, so as to complete the detection of icing conductor gravity. This mechanical sensor has been installed and has operated on Zila DC 400 kV transmission lines.
