摘　　要：弓网动态耦合为列车提供直流牵引电源,连续且可靠的供电是地铁运营安全性和可靠性的重要保证。受电弓和接触网作为车辆与供电两个系统的主要接口,随着轨道交通维修管理要求的不断提升,弓网关系成为制约牵引电能传输可靠性的关键因素之一。本文根据实际运行工况,对弓网异常的典型案例进行分析探究,并结合运维经验提出改善建议及对策。The dynamic coupling of pantograph and catenary provides DC traction power for trains,and continuous and reliable power supply is an important guarantee for the safety and reliability of subway operation.As the main interfaces between the vehicle and power supply system,the pantograph-catenary relation has been becoming one of the key factors restricting the reliability of traction power transmission with the continuous improvement of maintenance and management requirements in urban rail transit lines.The paper analyzes and studies the typical cases of pantograph-catenary abnormalities based on actual operating conditions,and proposes improvement suggestions and countermeasures with reference of operation and maintenance experience.
