受电弓作为接触网受电地铁车辆获取电能的关键设备,其质量好坏对地铁安全运营至关重要,因此其各项参数实时检测显得非常必要。本文介绍了地铁受电弓状态动态检测系统的组成,重点介绍了检测系统应用的关键检测技术和在国铁系统中发挥的检测作用,并研究了检测系统在地铁受电弓检测中的应用方案。 The pantograph is the key equipment for getting electricity from subway vehicles by catenary. The quality of the pantograph is very important to the safe operation of the subway. Therefore, it is very necessary to detect all the parameters in real time. This paper introduces the composition of the dynamic monitoring system of the pantograph state of the subway, especially introduces the key detection techniques used in the detection system and the detection functions in the national railway system. The application scheme of the detection system in the pantograph detection of the subway is also studied .
