铁路信号多方向进路表示器显示方式及控制电路探讨

以《铁路技术管理规程》中6方向和7方向发车进路表示器的排列显示规定为基础,分析提出8方向、9方向发车进路表示器的排列显示方式,并在呼和浩特南站得到具体应用。同时提出"按表示器数量设置表示继电器"的进路表示器控制电路方案,该方案比传统的"按方向数量设置发车方向继电器"控制电路方案更加优化控制电路,节约工程投资,降低维护成本。

Approach to Display Mode of Multi-direction Route Indicator and its Control Circuit in Railway Signaling

Based on the provisions in current Railway Technology Management Regulations for sixdirection and seven-direction departure route indicators,the paper analyzes and puts forward the display arrangement and mode for eight-direction and nine-direction departure route indicators,which are applied in Hohhot South Station. Meanwhile,a control circuit program for route indicator is proposed based on the dependence of the relay setting on the number of indicator. The program is more advantageous in control circuit optimization,less engineering investment and low maintenance cost than the traditional program which is based on the dependence of the setting of the departure direction relay on the number of directions.
