Working Principle Of Electric Locomotive

Trolley Electric Locomotive

The working process of the overhead line type electric locomotive is reduced and rectified by the traction converter. The positive pole is connected to the overhead line and the negative pole is connected to the rails. The pantograph on the locomotive comes into contact with the overhead line, draws current into the car, and then enters the traction motor through the air automatic switch, controller, and resistance box to drive the motor. The electric motor drives the wheels through the transmission device, thereby traction the train. The current from the motor flows back to the substation via the track.

Battery electric locomotive

The working principle of a battery electric locomotive is similar to that of a wire-type electric locomotive. The direct current provided by the battery drives the motor through components such as flameproof plugs, controllers, and resistance boxes, thereby traction trains.
