Traction Refurbishment Services
In a constant pursuit to provide the perfect solution to the rail industry, Dynex has assembled a highly specialised Traction Refurbishment services team as part of the Power Assemblies Business Unit. This team combines over 15 years of rail maintenance experience with our semiconductor capabilities to improve rolling stock life cycles and maintenance costs.
Dynex Power Assembly Refurbishment
We provide a service where we can strip, and improve the older sub-systems to provide regenerated parts which will ensure future performance is guaranteed.
As an original supplier into the UK traction market for power electronics devices, Dynex is now offering a service whereby we will renovate older systems that have been performing well in the field to prepare them for ongoing future operation.
We work with GTO and IGBT based systems, this work has included semiconductor device replacement as well as modifications which remove known failure mechanisms and improve the rail MTBF statistics significantly.
Where appropriate, Dynex can also provide on-site load testing of refurbished assemblies to ensure full and correct functionality with full traceability to ensure the work is carried out to a high level of quality.
Midlife Electric Rolling Stock Propulsion Upgrade
In the last two decades of the 20th century, power electronics has conquered its place with Gate Turn Off Thyristors for railways traction applications, as per metropolitan light trains, electric multiple units or locomotives. Eurosprinter, TRAXX and Prima electric locomotives from Siemens, Bombardier and Alstom are an example of this success for high power applications. A new generation of power semiconductors is now available for traction upgrade projects, to improve and extend midlife rolling stock maintenance.
Remote Condition Monitoring for Rail Applications
Remote Condition Monitoring (RCM) can be applied to monitor any aspect of the locomotives functions either electrical or mechanical and can be particularly beneficial to operators to prove problem causation.
Traction Power Electronics; Dynex RCM systems can report on critical data from the power electronics systems to enable determination of potential problems before there is a catastrophic failure. Critical temperatures and operational voltages can be constantly reported on the 3G/4G network in relation to torque, speed, and geographic location. This is enabling the operator to make real-time decisions to avoid breakdowns.
