A pantograph descending control device comprises an air inlet, a safety valve, a two-way throttle valve, a main air path pressure monitoring valve, an air outlet, an exhaust throttle valve I, a protective air path pressure monitoring valve, an exhaust throttle valve II, an upper cover, a base, a valve seat and an air bin; the air inlet is connected with a two-way throttle valve through an air path; the two-way throttle valve is connected with a safety valve, a main gas circuit pressure monitoring valve and a protective gas circuit pressure monitoring valve through gas circuits; the protectivegas circuit pressure monitoring valve is connected with the exhaust throttle valve II and the gas bin through a gas circuit, the gas bin is connected with the main gas circuit pressure monitoring valve through a gas circuit, and the main gas circuit pressure monitoring valve is connected with the exhaust throttle valve I and the gas outlet through a gas circuit to form a pantograph descending control module. The pantograph descending control device can monitor abnormal working conditions, and when the pantograph is in a low-pressure air supply state, protection is started, compressed air in the pantograph is forced to be exhausted, and automatic pantograph descending is achieved.
受电弓降弓控制装置,包括进气口、安全阀、双向节流阀、主气路压力监测阀、出气口、排气节流阀Ⅰ、保护气路压力监测阀、排气节流阀Ⅱ、上罩、底座、阀座和气仓;进气口通过气路与双向节流阀相连,所述双向节流阀通过气路与安全阀、主气路压力监测阀、保护气路压力监测阀相连,保护气路压力监测阀通过气路与排气节流阀Ⅱ、气仓相连,气仓通过气路与主气路压力监测阀相连,所述主气路压力监测阀通过气路与排气节流阀Ⅰ、出气口相连,组合成降弓控制模块。本发明能针对非正常工况进行监测,当受电弓处于低压供风,启动保护,迫使受电弓内的压缩空气排出,实现自动降弓。
