Work Process Of Electirc Locomotives

Underground mining locomotive are mainly divided into trolley locomotives diesel locomotive and battery locomotives also called electric locomotives.

1. Working process of trolley locomotive

After voltage reduction and rectification by 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 contacts with the overhead line, introduces the current into the locomotive, and then enters the traction motor through the air automatic switch, controller and resistance box to drive the motor to run. The motor drives the wheels to rotate through the transmission device, thus tracting the train. The current from the motor flows back to the converter through the track.

2. Working Process of Battery Electric Locomotive

The DC power supplied by the storage battery enters the motor through flameproof pins, controllers and resistance boxes, and drives the motor to run. The motor drives the wheels to rotate through the transmission device, thus tracting the train.
