    • PURPOSE: A normal state and a reverse state indication lamp are provided to prevent the malfunction of a signal by driving a indication lamp by being controlled to a current state of an indication relay. CONSTITUTION: A normal state indication lamp(200) is assembled in a protection case, is installed in a branch point of a railway line, and is driven in the normal state. A reverse state indication lamp(300) is assembled in the protection case, is installed in the branch point, and is driven in the reverse state. A current switch(201,301) opens and closes the driving current of the reverse state indication lamp and the normal state indication lamp. A drive current supplier(150) supplies a driving current to the normal and reverse state indication lamp through the driving current switch. The protection case protects the normal and the reverse state indication lamp from the wind and rain and the thunderstroke.
    • 目的:提供正常状态和反转状态指示灯,以通过将指示灯控制到指示继电器的当前状态来驱动指示灯来防止信号的故障。 构成:正常状态指示灯(200)组装在保护壳中,安装在铁路线的分支点,并在正常状态下被驱动。 反转状态指示灯(300)组装在保护壳中,安装在分支点,并以相反的状态驱动。 电流开关(201,301)打开和关闭反向指示灯和正常状态指示灯的驱动电流。 驱动电流供应器(150)通过驱动电流开关向正常和反向状态指示灯提供驱动电流。 保护套保护正常和反向状态指示灯免受风雨和雷击。
