ZD6型双机牵引道岔控制电路存在问题及改进

Problem and Improvement of ZD6 Dual Traction Switch Control Circuit

从坂田站道岔大修施工联锁试验发现的问题入手,分析电路原理,查找问题源头,探求解决方案,理顺双机直流牵引道岔启动电路的动作逻辑,改进电路联锁,提高电路安全。

Starting with the problems encountered in the interlocking test of major overhaul of turnouts in Sakata station, the principle of the circuit is analyzed and the root design problem is sought out. Furthermore, a solution has been explored to streamline the operation logic of the startup circuit of the switch machine with dual DC traction and to further improve circuit interlock for better safety of the circuit.
