摘　　要：随着电气化铁路接触网运行年限及运行弓架次的增加,高、普铁线路传统接触网整体载流吊弦断丝、断股、断脱缺陷频发,尤其是高铁运行7年或50万弓架次后吊弦缺陷尤为突出。本文结合无螺栓吊弦在广深铁路Ⅰ/Ⅱ线运行服役、高铁接触网三级修及新线建设中推广应用的效果,针对设计、产品、施工环节存在的问题提出解决建议,以提升设备质量,确保设备本质安全,降低供电设备全生命周期运维成本。Traditional OCS on high-speed and conventional railway lines often suffer from wire breakage,strand breakage,and detachment defects,especially after 7 years of operation or 500,000 times of passing through of catenary.The paper,combining with the effects of promoting the application of bolt-free dropper in the operation and service of line I/II of Guangzhou-Shenzhen railway,the three-level maintenance of OCS high-speed railway,and the construction of new lines.It proposes solutions to the problems in design,product,and construction to improve equipment quality,ensure intrinsic safety of equipment,and reduce the full life cycle operation and maintenance costs of power supply equipment.
