Study on Scheme of Catenary Operation Car with 160 km/h Instead of Hot Standby Locomotive

为提升高速铁路的应急救援能力,进一步优化热备动车组、热备机车的配置和布局,本文研究利用时速160 km接触网作业车代替热备机车救援动车组的方案可行性。在搜集BR711C型时速160 km接触网作业车技术参数及牵引特性数据的基础上,本文计算了该型作业车单机、双机救援CR400BF型动车组在不同坡道下的起动加速度、平衡速度、液力制动调速能力、空气制动停车能力等。计算结果表明:时速160 km接触网作业车代替热备机车在一定坡道条件的限制下可行。

In order to improve the emergency rescue capability of high-speed railway and further optimize the allocation and layout of hot standby EMU and hot standby locomotive,this paper studies the scheme that is to use catenary operation car with 160 km/h instead of hot standby locomotive for rescue of EMU.The result shows that the scheme is feasible.On the basis of technical parameters and traction characteristics data of BR711C catenary operation car with 160 km/h,this paper calculates the starting acceleration,balance speed,hydraulic braking speed regulation capacity,air braking parking capability under the different ramps of the single operation locomotive and double operation locomotives for rescue of CR400BF EMU.The calculation result show that it is feasible to replace hot standby locomotive with catenary operation car with 160 km/h under the constraint of certain ramp conditions.
