The most common failures of electric generators at dumpers BELAZ 75135

The aim of this paper is to point out the electrical equipment that is subject to frequent break-downs in BELAZ dumpers75135, 75145 and other types of dumper trucks that are represented in our mines especially in open-pit mines. The transmission of power from the diesel engine to the drive wheels is...

description The aim of this paper is to point out the electrical equipment that is subject to frequent break-downs in BELAZ dumpers75135, 75145 and other types of dumper trucks that are represented in our mines especially in open-pit mines. The transmission of power from the diesel engine to the drive wheels is carried out using a synchronous generator (electric generator) which is in an elastic connection with the diesel engine and the drive electric motors, which are located in the reducer wheels. The most common failures are on the electric generator that produces electric energy and the contactors with which it is produced management of power transmission from electric generator to electric engine. In the case of electric generators, failures mostly occur on the rotor: overheating of the poles of the rotor winding, which causes their burning as well as cracking of the so-called dovetail rotor half. The causes of these failures are mainly increased vibrations of the rotor poles themselves and are the result of improper balancing and loosening of the anchor bolts during the time. As the causes of failure are mostly mechanical in nature, we will devote special emphasis to that problem.
