Inspection/maintenance operations on towers

Applicable scenarios: For situations where the generator fault is relatively minor and does not require dismantling of core components, such as:

1. Sensor calibration

2. Repair of loose wiring terminals

3. Troubleshooting of minor faults in the cooling system

4. Local insulation treatment of stator/rotor windings

Service Process

Remote diagnosis: Initially locate the fault type through the wind turbine operation data platform and determine whether conditions for on-tower maintenance are met

On-site service: Engineers arrive at the wind farm with specialized tools, complete safety briefings, and then proceed to the engine room for operations

Test and acceptance: After maintenance is completed, initiate no-load/load tests on the generator to confirm that the fault has been eliminated

Report delivery: Submit a maintenance report, recording the cause of the fault, maintenance measures, and subsequent operation and maintenance suggestions

Core advantages: No need for disassembly and lifting, shortened downtime (usually completed within 24-48 hours), reduced lifting and transportation costs, suitable for handling small batch failures in wind farms
