【摘要】 针对邯郸供电段辖内连续三次出现的牵出线承力索断线故障,通过实地测量分析了牵出线机车取流时各支路间的电流分配关系,讨论了特殊情况下的接触网线索间的电位差,并针对设备现状提出了既有线通过增加门型电连接和增大交叉线索间接触电阻预防承力索断线的改进方案。更多还原

【Abstract】 With regard to the three typical examples of messenger wire broken in traction line occurred consecutively in section of Handan Power Supply Depot, the paper analyzes the current distribution relations among every branch circuit during the current collection by the train in traction line on basis of field measurement, discusses the potential difference between contact wires under specific cases, and proposes the improving plan on prevention of messenger wire from broken by means of increasing the gate type electrical connection and the resistance between crossing wires with regard to conditions of the existing equipment.更多还原
