秦沈客运专线接触网总体设计

Overall Design of Catenary for Qinhuangdao-Shenyang Dedicated Passenger Railway

从明确弓网系统及接触悬挂评价标准入手 ,通过对秦沈客运专线接触网设计的分析和总结 ,确立高速接触网的设计理论和方法。接触网是通过与其接触线相互摩擦运动的受电弓向电动车组或电力机车受流 ,弓网间稳定、良好的功率传输是实现高速行车的关键。为了衡量弓网间的受流质量 ,首先应确定对弓网关系进行评价的标准 ,而接触悬挂的评价标准则用于悬挂参数的确定。所选悬挂参数能否满足弓网间受流标准的要求并是否为最佳 ,需要通过计算机仿真或试验进行验证和优化。高速接触网的设计要体现安全、可靠和免维护性。因此 。

Starting with identifying evaluation criterion for pantograph\|contact line system and catenary, the design theory and method for catenary of high\|speed railway were determined based on experience from Qinhuangdao\|Shenyang Dedicated Passenger Railway. In a catenary system, power is led from contact line to electric motor train unit or electric locomotive through pantograph. A dependable and sound power transmission between pantograph and contact line is the key for high\|speed running of train. However, a criterion for evaluating pantograph\|contact line relation should be identified first to measure the quality of current collection, and this criterion shall be used for determining catenary parameters. To check if the parameters are up to criterion or optimum option, a computer simulation or test are needed for verification and optimization. Design of catenary for high\|speed railway should be safe, dependable, and maintenance\|free. Therefore, a concept of accurate design should be carried out throughout the design.
