乌鲁木齐西站驼峰场调车信号错开故障分析

Fault Analysis of Wrongly Opening Shunting Signal on Hump Yard of Urumchi West Station

乌鲁木齐西站II场在办理开放峰尾编3线的调车信号时,若编3线与编2线交汇处449#道岔因设备故障造成道岔定位无表示,将错误开放编2线的调车信号。为了解决因道岔无表示错误开放编2线信号的故障,在编2线调车信号机励磁电路中增加449#道岔的FBJ励磁接通条件,解决调车信号错误开放的故障。

When setting the shunting signal on classification track 3 at the hump end in the yard II of Urumchi west station, it may cause wrongly opening the shunting signal on classifi cation track 2 if switch 449 located at the cross point of classifi cation track 3 and 2 fails to give switch normal indication. For solving the problem above mentioned, FBJ energized condition in the circuit of the shunting signal on classifi cation track 2 is added for switch 449.
