普速铁路电气化改造隧道内接触网下锚补偿方案研究

Study on Tensioning Scheme for OCL Anchoring in Tunnel of Electrification Reconstruction of General Speed Railway

介绍了几种可用于隧道内的接触网下锚补偿装置,从工作原理、技术性能等方面进行了分析和比较。以某线路电气化改造为例详细分析了各种下锚补偿装置在既有普速铁路电气化改造工程隧道内的适应性,并重点分析了柱式弹簧补偿装置的应用及安装要求。

The paper introduces several kinds of OCL tensioning devices that can be used in tunnels,and analyzes and compares them from the aspects of working principle,technical performance.Taking the electrification reconstruction of a certain line as an example,the adaptability of various tensioning devices in the tunnel of existing general speed railway electrification reconstruction project is analyzed in details,and emphasis analyzing are given to the application and installation requirements of mast type spring tensioning device.
