南京地铁列车应急牵引允许控制电路的设计

Design of Permissible Control Circuit for Emergency Traction System of Metro Trains in Nanjing

原牵引允许控制系统电器故障对车辆牵引严重影响,极大影响行车效率,为此,在电路原理分析和充分考虑安全因素的基础上,提出了一套应急电路改进措施,改进后既能保障运行安全,又能提高运营效率,减少故障对运营造成的影响。

The malfunction of the electric apparatus of the former traction permissible control system severely affected the train traction system, and in turn, the efficiency of train operation. Therefore, on the basis of the analysis of the circuitry and full consideration of safety, a set of measures was taken to improve emergency circuit. As a result, failure rate is reduced and operation efficiency enhanced, while safety ensured
