简述LKJ通常工作状态下LKJ常用固定模式限速值和紧急固定模式限速值。

答案

参考答案:

根据《LKJ运用维护规则》的规定,常用固定模式限速值为:列车在恒速区运行,LKJ达到输出常用制动指令的速度值;紧急固定模式限速值为:列车在恒速区运行,LKJ达到输出紧急制动指令的速度值。在通常工作状态下,LKJ模式限速值按以下要求确定:

(1)按线路允许速度、接触网限制速度、机车最高运行速度、车辆最高运行速度、动车组最高运行速度、特定限速等各项最高允许速度和限制速度的最低值确定固定模式限速值;对于线路曲线半径为400m及以下的地段,按线路允许速度值下浮2km/h确定固定模式限速值。

(2)机车牵引的列车按固定模式限速值+5km/h确定常用固定模式限速值,按固定模式限速值+8km/h确定紧急固定模式限速值;对于侧向道岔和临时施工慢行引起的列车限速,特殊规定为:按固定模式限速值+3km/h确定常用固定模式限速值,按固定模式限速值+5km/h确定紧急固定模式限速值。

(3)动车组按固定模式限速值+5km/h确定常用固定模式限速值,按固定模式限速值+10km/h确定紧急固定模式限速值;对于侧向道岔和临时施工慢行引起的列车限速,特殊规定为固定模式限速值+3km/h确定常用固定模式限速值,按固定模式限速值+5km/h确定紧急固定模式限速值。
