Trolley locomotive

Working Principle

Trolley type electric locomotive working process of the high voltage alternating current (ac) after decompression by traction converter, rectifier, the positive to the overhead lines, the cathode to track. On the locomotive pantograph contact with overhead lines, to the introduction of the current car, automatic switch, controller, then through air resistance box into the traction motor, drive motor running. Motor through the gear drive wheel rotation, thus traction train. From motor electricity flows through the rail flow back to the converter

Parameter

Feature And Introduction

Trolley mining electric locomotive is lost by the traction converter of current through the electrical wiring into the electric circuit of electric locomotive and electric locomotive, repass track back to the converter. Underground lines of power grid in our country the dc voltage of 250 v and 550 v, open-air has two kinds of 550 v and 750 v

Trolley mining electric locomotive has simple structure, low cost, easy maintenance, the locomotive transport capacity is big, high speed, high power efficiency, transportation cost is low, the most widely used.

Application

Locomotive transportation system: the locomotive transportation is now mine main means of transportation in China. Main equipment orbit, harvesters, traction equipment and auxiliary equipment, etc., often with rake mine equipment and mining equipment, belt conveyor, or effective transportation system a trackless transport equipment, etc

In the process of production, transport ore, waste rock, materials, equipment and personnel, etc., it is to organize production, decided to mine production capacity is one of the main factors.
