| 摘要 |
A hydraulic transmission which finds particular applicability in a wind turbine generator has a pump (4) for connection to a rotor of the turbine for generating pressurised fluid, a motor (8) driven by pressurised fluid for connection to a electricity-generating device, a hydraulic fluid conveyor (6) between pump and motor; and a condition monitoring system comprising a number of sensors (34) disposed in one or both of the pump and motor, connected to a condition processor (36) configured to process the sensor output to provide a processed image or signature from which structural or operational abnormalities can be identified. |
