CONTROL SYSTEM FOR A TRACTION ALTERNATING-CURRENT ELECTRIC DRIVE FOR A MINE ELECTRIC LOCOMOTIVE

摘要

The proposed control system for a traction alternating-current electric drive with two asynchronous motors designed for a mine electric locomotive contains a control console, a protection and testing unit, a frequency converter with a voltage inverter, and an independent power-supply unit. The inverter contains to bridge circuits with power thyristors connected reversely in parallel. Each motor is connected to the output of the corresponding bridge circuit.
