城市轨道交通架空刚性接触网汇流排载流能力

摘要

分析了列车在城市轨道交通系统中的取流以及架空刚性接触网汇流排相应的载流。提出采用间歇性负荷循环电流的特性波形确定汇流排的载流能力,对通用架空刚性接触网既有汇流排进行了连续性负荷和间歇性负荷循环电流发热试验,对试验结果进行了对比分析。%After an analysis on the current collection by train operated in urban rail transition system and the relevant current carrying capcity demand on conductor rail in overhead contact system, it is recommended that a periodical cyclic loaded current wave form for rating and test verification of the current carrying capacity of conductor rail be adopted. Heat run tests both under continuous loaded and periodical cyclic loaded current for conductor rail popularly used in existing overhead contact line system are conducted and the results are compared and analysed .
