摘要
高速铁路 42#道岔接触网采用第三辅助锚段无交分线岔布置方式,由正线锚段悬挂、侧线锚段悬挂及辅助锚段悬挂组成.42#道岔接触网辅助锚段悬挂起着正线锚段悬挂与侧线锚段悬挂的衔接作用,保证了受电弓在正线锚段与侧线锚段的平稳过渡,因此辅助锚段悬挂的线材及张力选择显得尤为重要.通过调研目前42#道岔接触网辅助锚段线材及张力的设置情况,从线材张力配置、波动传播速度、与正线锚段匹配性等方面进行分析;并利用弓网仿真,通过分析不同线材及张力组合,提出适应不同时速的42#道岔接触网辅助锚段线材及张力选择,应用于实际工程中,为今后 42#道岔接触网辅助锚段线材及张力设计提供了方案参考.
Abstract
The No.42 turnout adopts the third auxiliary anchor non-crossing crossover for the Overhead Contact System in No.42 turnout in high-speed railway,which is composed of the main line anchor section,lateral line anchor section and auxiliary anchor section.The auxiliary anchor section plays the connecting role of the main line anchor section and lateral line anchor section in No.42 turnout,and it provides the smooth transition from the main line an-chor section to the lateral line anchor section for the pantograph,so the cable and tension are important for the auxilia-ry anchor section.By investigating the setting of the cable and tension of the auxiliary anchor section in No.42 turn-out,the analysis is carried out from the tension configuration,wave propagation velocity and the matching with the main line anchor section.By analyzing different wire and tension combinations,a selection of wire and tension for the auxiliary anchor section of the 42#turnout contact network that is suitable for different speeds is proposed.The re-sults are applied to practical engineering and provide a reference for the future design of the cable and tension of the auxiliary anchor section in the No.42 turnout.
