INTEGRATED CONTROL SYSTEM FOR REGULATION AND PREVENTION OF OVERHEATING IN TRACTION ELECTRICAL ENGINES OF MINING LOCOMOTIVES

Abstract

Presented herein is a new optimized system of temperature control for traction engines in mining locomotives, which can be easily integrated into the main automatic control and diagnostics system onboard the locomotive. It is based on the control of the temperature of the excitation winding using the "ammeter-voltmeter" method forming a signal when the maximum permittable operating temperature of the engine is reached.
