地铁弓网系统受流试验及评估分析

Current collection test and evaluation analysis of metro pantograph and overhead contact wire system OCS

地铁列车通常采用电力驱动,弓网系统是地铁列车获取电能的主要方式,弓网系统的受流性能对地铁列车的安全运营起关键作用。因此,新建地铁线路开通或新车上线运营之前,通常需对弓网系统的受流质量进行线路试验评估。文章首先介绍弓网系统的试验内容、试验方法和评价指标,然后,基于先期积累的弓网线路试验数据,对弓网接触压力、弓网燃弧、受电弓垂向加速度等评价指标提出合理化建议,以期为地铁弓网系统的受流质量评估提供参考。

Metro trains are usually driven by electricity,and pantograph and overhead contact wire system is the main mode for metro trains to obtain electric energy.The current collection performance of pantograph and OCS plays a key role in the safe operation of metro trains.Therefore,the current collection quality of pantograph and OCS should be tested and evaluated before the new metro line is opened to traffic or the new vehicle is put into operation on metro line.This paper fi rst introduces the test details,test method and evaluation index of pantograph and OCS.Secondly,based on the accumulated pantograph and OCS and track test data,the paper puts forward proper suggestions on the evaluation indexes such as pantograph and contact wire contact pressure,pantograph and OCS arcing,pantograph vertical acceleration,etc.,in order to provide reference for current collection quality evaluation of metro pantograph and overhead contact system.
