针对自动闭塞四线制方向电路比较复杂,故障难以判断和处理的问题。以双线双向自动闭塞方向电路为例,介绍了方向电路的动作流程,具体分析了控制电路及监督电路故障的区分、判断处理,以及在采用正常方式无法改变列车方向的异常情况下,应采取的应急处理方法。以典型方向电路故障为例,说明提高电务维护人员的应急处理能力,对压缩故障延时的重要性。
For the automatic block four-wire direction of the circuit is more complex, difficult to judge and deal with the problem. Taking the bidirectional automatic two-way blocking circuit as an example, the operation flow of the directional circuit is introduced. The distinction and judgment of the control circuit and supervisory circuit are analyzed in detail. In the abnormal situation that the normal way can not change the direction of the train, Emergency treatment methods. Taking a typical directional circuit fault as an example, it shows the importance of improving the emergency handling capability of the maintenance staff and reducing the delay of the compression fault.
