A brief introduction of 1.5T Overhead Line Electric Locomotive products
The traction voltage of 1.5 ton locomotive is 100V and 250V. Its structure has two kinds of inner frame, outer frame, are resistance deceleration car. It has the characteristics of stable operation, flexible, simple operation, easy maintenance and overhaul. The braking effect is good. The working process of 1.5T Overhead Line Electric LocomotiveAfter the high voltage alternating current is reduced and rectified by the traction transformer, 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, and the current is introduced into the car, and then enters the traction motor through the air automatic switch, controller and resistance box to drive the motor to run. The electric motor drives the wheels through the transmission device to pull the train. The electricity flowing from the motor flows through the track and back to the converter. The operating environment of 1.5T narrow gauge cabling electric locomotive 1, the highest temperature of the surrounding air is 40℃ and the lowest is -25℃. 2, the relative humidity of the air is not more than 90%, and the average minimum temperature of the month is not higher than 25℃. Note: The maximum traction force of the locomotive is determined according to the adhesion coefficient μ=0.25 between the wheel and the rail, and the maximum traction force can only be used for short-term start-up.
