Pantograph and Catenary Arc under Stiff Contact Wires of 120 km/h Metro Vehicles

Aiming at the 120 km/h vehicles pantograph and catenary arc of Guangzhou metro line 3 north-extension section,the arc generation cause was analyzed,and the pantograph and catenary model was built.With the simulation from the pantograph and the catenary,the pantograph and catenary parameters for 120 km/h vehicles operation were provided.The test validated the good effects.
