Automatic diagnostics of motor driven rolling stock electric circuits


Revolutionary increase the repair quality of motor driven rolling stock (MDRS) and simultaneously reduce duration and laboriousness of obligatory after-repair control is possible by means of automatic systems for comprehensive diagnostics with automatic expert system of malfunctions detection, excluding subjective diagnose errors and providing reliable assessment of the most complex and critical systems of an EMU-train.

The article describes the system for comprehensive diagnostics of EMU-train sections COMPACS®-EXPRESS-TR3, which includes 7 sub-systems for the diagnosing of the most complex and damageable assemblies and units – wheel-motor units, isolation of high-voltage electric circuits, pantographs, compressed-air braking system control circuits, power and auxiliary electric circuits.

Due to the usage of the sub-system for electric circuits diagnostics, which is the part of the COMPACS®-EXPRESS-TR3 system, for the first time a possibility to detect details and devices, which condition leads to the decrease of a train productiveness and deterioration of operation conditions of electric machinery and a switchgear, to make the personnel’s work to be aimed at the liquidation of the particular defects, and not all the probable malfunctions, increase of the particular elements’ repair quality, reduction of the train after-repair control and checkout operations in more than 6 times.

The developed methodology of electric circuits diagnostics on the basis of the COMPACS®-EXPRESS-TR3 system allows to make EMU-train electrics checkout faster and easy during the commissioning with the help of prompt, timely and qualitative assessment of control, power and auxiliary electric circuits’ condition.
