摘要
针对中心锚结缺失引发二次故障,分析了中心锚结的功能,提出了处理中心锚结故障时应首先恢复其防窜功能,同时应防范曲线区段腕臂偏转与长大坡道上的重力分力对接触网窜动的影响;对既有接触网改造提出及时安装中心锚结建议,防止中心锚结缺失危及接触网运行安全。
For triggering of second time faults due to loss of mid-point anchor, the paper analyzes functions of mid-point anchor, puts forward a principle that the play-resistant function of mid-point anchor shall be restored firstly when mid-point anchor faults are being disposed, at the same time, protection measures shall be taken to prevent the play-resistant function for overhead contact system from being affected by deflection of cantilever at curve section and weight component generated by the long and steep slope track; proposals on timely installation of mid-point anchor for reconstruction of overhead contact system are put forward so as to guarantee that the overhead contact system operation will not be endangered by the loss of mid-point anchor.
