Lobnya depot: Response to the Comprehensive System for EMU Sections Diagnostics COMPACS-EXPRESS-TR3

During 1.5 of a year Comprehensive System for EMU Sections Diagnostics COMPACS^®-EXPRESS-TR3 is used as the prime tool of quality control in production of EMU current repair of large volume (TR-3).

COMPACS^®-EXPRESS-TR3 is designed for quick condition assessment of the most complex and critical EMU equipment: electrical control circuits, power and supplemental circuits, airbrake system, collectors. The system allows carrying out fine-tuning and adjustment of equipment, with minimal labor and energy resources, bringing their parameters to the requirements of safe and trouble-free operation, and also helps to identify hidden defects in the "problem" electrical sections.

42 electrical sections, repaired under the program TR-3, have been diagnosed during the system operation. At first a number of detected defects was significant and reached 11-13 per section, but the systematic repetition of the same defects allowed adjusting the technological cycles of repair and equipment tests in the production areas of these works in such a way that prevents the installation on the train of low-quality units and devices. Today the number of detected malfunctions is significantly reduced and does not exceed 6-7 per electrical section that clearly indicates repair upgrading.

The use of COMPACS^®-EXPRESS-TR3 allowed to improve reliability and safe operation of EMU on the Moscow railway.
