Altayskaya Depot: Response to the operation of the COMPACS-EXPRESS-TR3 system for comprehensive diagnostics of units of EMU-trains

The system for diagnostics of units of EMU-trains COMPACS^®-EXPRESS-TR3 has been successfully operating in the Altayskaya depot since 2008. More than 3100 technical readiness reports were created when diagnosing wheel-motor units (WMU), isolations, pantographs, pneumatic braking system, electric control circuits, power and auxiliary circuits of electric trains.

Today, the Altayskaya depot uses three different systems for WMU vibration analysis. Although, the traction motor control unit causing rotation of the wheel pair in a set mode is included in the COMPACS^®-EXPRESS-TR3 only. Besides, to test WMU with the COMPACS^®-EXPRESS-TR3 requires much less labour force and time (more than 10 times in comparison to other systems used) due to application of 6 vibration sensors and fully automatic diagnostics with prompting on maintenance and repair of WMU assemblies.

Considering the positive experience of the system’s operation, the Altayskaya depot is looking forward to further cooperation with the COMPACS^®-EXPRESS-TR3 and recommends to all reaserch&development personnel of DYNAMICS SPC to consider the variant of the COMPACS^® system for application at all technological positions, which would allow to have a common regulatory base of diagnostic parameters, and, consequently, to increase the observability of maintenance and repair of EMU-trains.
