The Comprehensive System for EMU Sections Diagnostics COMPACS®-EXPRESS-TR3, designed to assess repair quality of assemblies and electrical multiple units of ER9T and ED9 series (m, m, n) after the maintenance TR3, was put into operation in depot Anisovka in September 2008.
During the operation period, 36 electrical sections, passed a large amount of repairs in the depot, were completely debugged with the help of the system. All malfunctions, detected by the system, were confirmed by the results of further breaching and inspections, required by the system. A lot of malfunctions could not be found during traditional breaking-in tests and debug under the contact wire. The result of pass of such malfunctions in operation could be defects and failures of itinerary with significant delays in time-schedule.
The positive properties of the system COMPACS®-EXPRESS-TR3 are as follows:
High reliability of diagnostic results.
Efficiency of diagnosis receipt and a high degree of automation.
High coverage of diagnosed assemblies and units, including: wheel reduction gear units, isolation of high-voltage circuits, pantograph, equipment of compressed-air braking system, air brake systems, electrical control circuits, power and supplemental electrical circuits.
Way of presenting information of the electrical section state on diagnostic results, saving the results in memory, printing test reports for each subsystem and whole electrical section.
Gained experience during the system operation allows us to conclude that the system COMPACS®-EXPRESS-TR3 is a modern, powerful and convenient tool, irreplaceable during repair and debugging, as well as fine-tuning and adjustment of the basic and most critical assemblies electric multiple unit.
Using the system provides a reliable and well operation of EMU equipment for a long period of time ensuring a high level of safety and regularity of the railway transport operation.
