A semi-active pantograph pneumatic control system of the present invention comprises: a first solenoid valve (Sol.1) that controls air pressure through bellows of a pantograph to adjust the air pressure rising and falling operation of the pantograph; a second solenoid valve (Sol.2) for operating a pantograph up-limiting device (ULD); a third solenoid valve (Sol.3) for setting the pressure and operating an emergency control switching valve; and a switching valve (isolation valve) for mode selection. Accordingly, the supply pressure is variable and can be easily controlled variably according to speed, providing the effect of controlling the air pressure supplied to the pantograph according to the setting mode, operation mode, and emergency mode.

    본 발명의 반능동형 팬터그래프 공압 제어 시스템은, 팬터그래프의 벨로우즈로 공기압을 제어하여 팬터그래프의 공압 상승 및 하강 작동을 조정하는 제1솔레노이드밸브(Sol. 1); 팬터그래프 상승제한 장치(ULD) 작동용 제2솔레노이드밸브(Sol. 2); 압상력 설정 및 비상제어 절환 밸브 작동용 제3솔레노이드밸브(Sol. 3); 및 모드 선택용 절환밸브(Isolation valve)를 포함하는 것을 특징으로 한다. 이에 따라, 공급압력이 가변적이며 속도에 따라 가변제어가 용이하여 설정모드, 운행모드 및 비상모드에 따라 팬터그래로 공급되는 공압을 제어하는 효과를 제공한다.
