摘　　要：京津城际铁路是中国第一条运行时速350 km的电气化铁路,至今已运营10余年,为分析其接触线的磨耗状态及变化规律以指导接触网的维修,本文基于京津城际接触网磨耗测试数据,对比分析了锚段关节、吊弦点和跨中接触线的磨耗数据,分析磨耗规律,给出维修建议,并基于接触线的平均磨耗数据和最大磨耗数据依据标准估算其使用寿命,指出锚段关节过渡跨的接触线是磨耗的重点监测点。Beijing-Tianjin Passenger dedicated line is the first electrified railway line with speed over 350 km in China,and it has been operating for 10 years up to now.In order for analyzing the wear status and variation regularities of its contact wires so as to guide the maintenance of OCS,the paper,on the basis of wear test data of contact wires for Beijing-Tianjin passenger dedicated line,compares and analyzes the data of wear of contact wires at overlap section,dropper point and mid-span,analyzes the wear regularities,and puts forward the maintenance proposals;with the service life of the contact wire estimated in accordance with the relative standard on the basis of data of average wear and maximum wear of contact wires,the paper puts forward that the contact wires at transitional span in overlap section are the key monitoring points for wear of contact wires.
