The invention discloses a device for relieving emergency braking of a motor train unit and the motor train unit, and relates to the technical field of motor train units. The device comprises a loop bypass switch, a loop relay and an emergency braking loop; the emergency braking loop controls emergency braking of the motor train unit after detecting that a coil of the loop relay loses power; after a mechanician determines that a passenger mistakenly triggers the emergency braking handle, a normally open contact of the loop bypass switch is closed by triggering the loop bypass switch, so that a coil of the loop relay is electrified, and when the emergency braking loop detects that the coil of the loop relay is electrified, braking of the motor train unit is relieved. Therefore, when a passenger mistakenly triggers the emergency braking handle, a mechanician does not need to manually restore the emergency braking handle to a non-triggered state in a compartment where the emergency braking handle is triggered, time and labor are saved, and normal operation of the motor train unit is not affected for a long time.
本发明公开了一种缓解动车组紧急制动的装置及动车组,涉及动车组技术领域,包括环路旁路开关、环路继电器和紧急制动环路,当乘客误触发紧急制动手柄时环路继电器的线圈失电,紧急制动环路检测到环路继电器的线圈失电后控制动车组紧急制动;机械师确定是乘客误触发紧急制动手柄后通过触发环路旁路开关使得环路旁路开关的常开触点闭合进而使得环路继电器的线圈得电,当紧急制动环路检测到环路继电器的线圈得电时缓解动车组的制动。因此,在乘客误触发紧急制动手柄时机械师无需去紧急制动手柄被触发的车厢内手动将紧急制动手柄恢复到未被触发时的状态,省时省力,不会长时间影响动车组的正常运行。
