Converter cooling upgrade kit
The 3.6 MW generator converter is fitted with a fan panel assembly to provide essential forced cooling for the power devices in the power cubicle. These assemblies comprise of a row of three fans operating together to maintain a cooling airflow while the drive is in operation.
Upgrade kit
The upgrade kit includes the necessary protection MCB’s, auxiliary contact blocks, cable assemblies and full work instructions for installation by a GE trained service engineer.
The cooling fan protection upgrade requires minimum installation time as well as no special tool requirements.
Benefits
- Fan isolation – During fan failure, the failed fan is isolated, and the remaining fans will operate.
- Activated warning – Sent to the converter controller highlighting a fan has failed and has shut down.
- Warning alarm – Alarm trigger by the cooling upgrade kit.
- Helps turbine to keep running – Reduces unplanned downtime due to single fan failures.
- Perform planned maintenance – Cooling upgrade kit helps to replace the failed fan during scheduled maintenance. The replacement can be planned at a convenient time by the wind farm operator.
Converter replacement fan
In addition to the fan upgrade kit, GE has developed a new enhanced cooling fan with hybrid bearing system, which protects from external influences, avoiding bearing currents.
Benefits
- Low risk fit form and function replacement
- Greater protection from external influences
- Reduced heat build-up
- Helps converter to keep running in case of single fan failures
