EDF's Durance Verdon hydroelectricity basin consists of 17 dams and 30 power stations with a total installed capacity of 2200MW and production of 6.5 billion kWh. Most of the power plants have been in use thirty years or more and maintenance operations are vital to ensure optimum production. Verlinde hoists are installed at all plants and have to meet very specific operating conditions.
NORD DRIVESYSTEMS supplies efficient drive units for dynamic speed control and automatic process control in applications that need to be regularly cleaned with high-pressure steam jets. Developed for strict hygiene requirements and featuring IP66/IP69K ingress protection, smooth-surface motors with an integrated frequency inverter are available for the 0.37..1.1 kW performance range. Common applications include conveyors, pumps, mixers, and agitators. Sensor data such as pressure or flow rate values can be directly communicated to the drives, enabling them to automatically adapt to current demand. If partial load operation is frequent, an automatic energy-saving function decreases the running costs by a significant share. In conveyor applications, light barriers can be used for contact-free or gapless accumulation. A soft start function reduces the starting current and results in less stress on the mechanical system and the transported goods.
