摘要
在转辙机的控制上,三开道岔由2台单动道岔转辙机牵引,需要互相检查互相锁定。对天津地铁6号线的控制电路进行分析,增加XDJ单元电路,较少修改既有道岔控制电路,可实现三开道岔的正常运用。
Three-way switch is driven by tow single action switch machines and mutual check and mutual locking of the two switches is required.The control circuit of the switches in Tianjin metro No.6 line is analyzed and a XDJ unit circuit is added.Less modifications of the existing control circuit of the switch are made to realize normal operation of three-way switches.
