AI Technical Summary

Technical Problem

Existing online monitoring systems for wind turbine gear oil fail to effectively monitor the gas components and concentrations in the gear oil, resulting in an inability to provide real-time warnings of gearbox status.

Method used

Design an online monitoring system for wind turbine gear oil. The system uses a combination of an ultrasonic vibration unit and a stirring mechanism to degas the gear oil and then uses a gas analysis unit to detect the gas components and concentrations. The system includes an oil treatment device and a gas analysis unit to monitor the gases in the gear oil.

Benefits of technology

This technology enables effective monitoring of gas in the gear oil within the gearbox of wind turbine units, improving the early warning capability of wind turbine unit operation status and ensuring the quality of gear oil and stable operation of the equipment.
