恒张力弹簧补偿器在地铁接触网中的应用

Application of Constant-tension Spring Tensioner in Metro OCS Anchoring

为适应新环境对接触网下锚补偿装置提出的要求,南京地铁在接触网下锚时使用恒张力弹簧补偿装置。阐述恒张力弹簧补偿装置的结构及工作原理,并将其与传统棘轮补偿装置进行对比;逐一分析恒张力弹簧补偿装置在不同条件下的应用,论证其在地铁应用的优越性。

In order to adapt the requirements of the OCS（Overhead Catenary System） anchoring,constant-tension spring tensioners were used in Nanjing metro.This article introduces the structure and working principles of this equipment and makes a contrast of it with the traditional wheel tensioning device.Moreover,it analyses the application of the spring tensioners in various working conditions in Nanjing metro and demonstrates their significant advantages.
