Takling About Working Principle Electric Wired Locomotive And Battery Locomotive

During the working process of the overhead electric locomotive, the high-voltage alternating current is stepped down and rectified by the traction converter, the positive pole is connected to the overhead line, and the negative pole is connected to the rail. The pantograph on the locomotive is in contact with the overhead line, and the current is introduced into the vehicle, and then enters the traction motor through the automatic air switch, the controller and the resistance box to drive the motor to run. The electric motor drives the wheels to rotate through the transmission, thereby pulling the train to travel. The current flowing from the motor flows back to the converter through the orbit.

The working principle of the battery type electric locomotive is similar to that of the overhead electric locomotive. The direct current supplied by the battery is driven by the flameproof plug, the controller, the resistance box and the like to drive the motor to drive the train.
