Working Principle Of Various Underground Mining Electric Locomotives

During the working process of the trolley type electric locomotive, after the high-voltage alternating current is depressurized and rectified by the traction substation, the positive pole is connected to the overhead line and the negative pole is connected to the rail.

The pantograph on the electric locomotive contacts with the overhead line, introduces the current into the vehicle, and then enters the traction motor through the air automatic switch, controller and resistance box to drive the motor. The motor drives the wheels through the transmission device, so as to drive the train. The current from the motor flows back to the substation through the track.

During the working process of battery electric locomotive, the direct current provided by the battery enters the motor through the explosion-proof bolt, controller and resistance box, and drives the motor to run. The motor drives the wheels through the transmission device, so as to drive the train.

The main production of underground mining locomotive factory in China coal industry and mine: battery motor frame, line type electric locomotive, electric locomotive accessories, underground mining locomotive
