Overhead Line Mining Electric Locomotive

Wired industrial and mining electric locomotive

The overhead electric locomotive is a small mining locomotive designed by the Equipment Industry Department of the Ministry of Geology and Mineral Resources and passed the ministerial appraisal. The overhead electric locomotive has the characteristics of large traction power, flexible machinery, low cost, simple operation and comfortable conditions. It is suitable for all kinds of mine cars, shuttle cars and mining equipment to pull and transport ore, tools, equipment and staff in tunnels and various working places.

1. Brief introduction and features

The 1.5 ton overhead electric locomotive is an old 1.5 ton overhead electric locomotive, and is now called CJY 1.5 ton overhead mining electric locomotive. The 1.5 ton overhead electric locomotive is an old 1.5 ton overhead electric locomotive, and is now called CJY 1.5 ton overhead mining electric locomotive.

The traction voltage of the 1.5-ton linear electric locomotive is divided into 100V and 250V, and adopts resistance speed regulation or IGBT speed regulation. Its structure has two types: inner frame and outer frame. Its characteristics: stable and flexible operation, simple operation, low maintenance and easy maintenance. Using expansion brake or electric brake, the braking effect is good.

2. Working process of 1.5T overhead electric 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 to drive the motor to run. The electric 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.

3. The use environment of 1.5T narrow-gauge overhead electric locomotive

1. The ambient air temperature is 40℃, 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 more than 25℃.

Note: The traction of the locomotive is determined under the condition that the wheel and rail adhesion coefficient μ=0.25. The traction can only be used during short-term startup
