刚性接触网折返线电气分段形式探究

Research on Electrical Sectional Form of Rigid Catenary Turn Back Line

本文介绍了城市轨道交通线路折返线位置刚性接触网电分段的形式和运行现状,结合分段绝缘器每天的弓架频次、通过时弓网关系、施工建设成本、运营维护等多方面研究。提出将折返线分段绝缘器改造成绝缘锚段关节式的形式,从而降低建设成本,减少运营维护工作量,杜绝因分段绝缘器引发的弓网故障,确保接触网设备运行安全可靠和地铁的平安运营。

This paper introduces the position of turn back line of urban rail transit line,the form and operation status of rigid catenary electrical section.Combined with the daily pantograph frequency of section insulator,the relationship between pantograph and catenary,construction cost,operation and maintenance,etc.The construction and maintenance of segmental insulation device of metro will be improved to ensure the safe and reliable operation of overhead contact line due to the transformation of segmental insulation device,so as to reduce the workload of segmental insulation device of Metro and reduce the operation cost of overhead contact line.
