What is the overhead electric locomotive? Today, the electric locomotive editor will talk about the performance and structural characteristics of the overhead electric locomotive! The overhead electric locomotive is operated by obtaining electric energy from the wire circuit by means of the "pantograph". When the overhead electric locomotive is turned on, the "pantograph" slides along the overhead wire in the air. It has great traction, strong anti-blocking ability, and strong braking ability. It is an indispensable tool for mining land.
1. The underground mining locomotive is drawn by the high-voltage cable from the central transformer substation, which supplies the traction converter and transforms it into AC power, which is reduced by the transformer, and then transported to the converter equipment through the low-voltage cable to convert the AC power It is direct current. The positive pole of the DC power supply is connected to the lead wire of the displacement wire, and the adjacent connection point becomes the power supply point of the electric locomotive. This is the power supply mode of the overhead electric locomotive.
When underground mining locomotive running, it runs along the track. The top end of the overhead electric locomotive relies on the "pantograph" to connect and squeeze the cable to obtain electric energy. The lower end uses the wheel to contact the track to form a loop to pull the line motor. The electric idea of the car, so that the overhead electric locomotive mobilizes the mine car to move.
2. The overhead electric locomotive is composed of two major departments: electrical equipment and mechanical structure
Mechanical structure: frame, wheel set, bearing and axle box, spring bracket, brake installation, Gaza installation, transmission installation, adjoining buffer installation, etc.
Electrical equipment: traction electric idea, controller, pantograph, automatic switch, starting resistor, lighting installation, etc.
