摘　　要：接触网作为电气化铁路基础设施系统中重要的组成部分,其运行效率和可靠性对整个供电系统的稳定性和经济性产生重要影响。随着运量增加和规模化开行长编组列车以及技术装备的更新迭代,电气化铁路技术装备运营维护压力急剧上升,其中接触网的零部件较为繁杂,现有6C系统可有效监测检测接触网系统的状态,但如何运用监测检测的数据并对其深入挖掘继而指导接触网的维修保养是目前亟待解决的难题。本文根据某线路实际检测数据,运用频谱分析的方法对接触网硬点数据进行研究,并分析硬点产生的原因,为现场克缺提供参考。As an important part of the infrastructure system of electrified railway,the operation efficiency and reliability of traction substation have an important impact on the stability and economic efficiency of the whole power supply system.With the increase of traffic volume,the large-scale operation of long marshalling trains and the renewal and iteration of technical equipment for a long time,the operation and maintenance pressure of technical equipment of electrified railway has risen sharply,and the OCS parts are more complicate,and the existing 6C system is able to effectively monitor and detect the OCS status.However,how to use the monitoring and detection data and dig it in depth to guide the OCS maintenance and servicing is an urgent problem needs to be solved.Based on the actual data of a certain line,the paper uses the method of spectrum analysis to study the data of OCS hard points,and analyzes the causes of generation of the hard points,providing reference for eliminating defects at site.
