The working process of 1.5T narrow gauge locomotive

The working process of 1.5T narrow gauge locomotive
The traction voltage of the 1.5-ton narrow gauge locomotive is 100V and 250V. The structure of the narrow gauge locomotive has two types: inner frame and outer frame, both of which are resistance deceleration vehicles. The narrow gauge locomotive has the characteristics of stable operation, flexibility, easy operation, and easy maintenance and repair. The narrow gauge locomotive adopts the brake expansion brake, and the braking effect is good.
The working process of the 1.5T narrow gauge locomotive:

After 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 car, and then enters the traction motor through the air automatic switch, controller, and resistance box, and drives the motor to run. The motor drives the wheels to rotate through the transmission device, thereby pulling the train to travel. The current from the motor flows back to the converter through the track.
