四线制改变运行方向电路存在问题及改进措施

Problems and Improvement Measures of Running Direction Changing Circuit with Four Wire

针对自动闭塞区间四线制改变运行方向电路存在的错误翻转问题,建议采用断开方向继电器电路外线的方式进行解决。经过改进,解决了方向继电器电路外线断开和接通的问题,保证了四线制方向电路的安全运用,减少了对运输的影响。

In view of the automatic block section four wire change direction error reverse problems of the circuit, the proposal uses off directional relay circuit outside way, solves the four wire change direction circuit error reverse problem. After improvement, solve the directional relay circuit outside the problem of disconnection and connection, to ensure the safe use direction of the four wire circuits, reduces the impact on transport.
