Repair of a drive for the Grand Tunnelier in the Paris region

576 1024 Flipo Richir

Flipo Richir’s teams worked in the Paris region for the Grand tunnelier. We carried out the troubleshooting of a 400kW drive. This operation was an opportunity to make the following changes:

  • of power cards
  • thyristors
  • of measurement cards
  • Track control boards
  • IGBT: The bipolar isolated grid transistor

In short, a big new move and it starts again!
