摘要
采用应变式传感器对准高速铁路接触网的动态应变量参数进行测量，分析了传感器的工作原理、温度补偿措施及动态测量误差，介绍了传感器的现场安装方法、测量系统的结构和光纤高低电压隔离信号传输方式，并得到了准高速下接触导线的应变测量曲线。
In this paper, the strain sensor is applied in the strain measurement for the catenary 's dynamic parametres in quasi-high-speed railway, the working principle of the sensor、the temperature compensation means and dynamic detecting errors are analyzed, the sensor's mounting method on-the-pot、the structure of system and the singnal transmission from the high to low voltage side with the optical fiber are also presented, the strain curves of the contact wire for the quasi-high-speed railway are getted pratically at last.
