Research on Braking Mode of Urban Rail Transit Accumulator Locomotive
Xiamen Metro Line 1～3 adopt ZER3 battery engineering cars produced by CRRC Zhuzhou Electric Locomotive Co.,Ltd.,and the braking system adopts DK-2.The braking system of the battery engineering vehicle of Line 1 and Line 2 adopts the air-electric hybrid braking mode.In this mode,when a separate brake controller is used(also known as small brake brake),the air-electric hybrid brake function automatically intervenes,but when the automatic brake controller is used(referred to as gate brake),there is no electric brake integrated intervention function.The braking system of Line 3 battery engineering vehicle belongs to the air-electric combined braking mode,which has the electric braking intervention function whether it is the main brake or the small brake.
