地铁柔性接触网线岔检调标准的制定与应用

根据以往运行经验,结合西安地铁2号线的实际情况,从支柱定位、线岔交叉点、始触区、接触线高度、线岔定位拉出值等方面,对柔性接触网线岔的检调标准进行深入研究、分析并加以明确。将所定标准实际应用在西安地铁渭河车辆段接触网的建设中,顺利通过了接触网的冷滑、热滑试验及实际运行的考验。同时,将所定部分标准与国铁普速接触网线岔检调标准进行对比,以供有关接触网生产和技术人员参考。

Discussion on the Adjustment Standards of Line Branches for Subway Flexible Overhead Catenary

According to the operation experience and the actual situations of Xi’an subway Line 2,the adjustment standards of subway flexible overhead catenary line branches have been studied and analyzed from the prop localizations,the intersection of line branches,the area of beginning touches,the catenary altitude,the pull out numerical values of line branches and so on.The adjustment standards of line branches have been determined and are used actually in the catenary erection of Xi’an subway Weihe River vehicles depot.Test of the standards has been passed smoothly under no current,sliding hotly and the actual operation.At the same time,partial standards have been contrasted with the standards of the normal speed railway centenary line branches,so that they are advantageous for the production and catenary technicians.
