Description
Technical Field
The utility model relates to the technical field of double-fed wind driven generators, in particular to a device for monitoring the temperature of an inner cover of a bearing of a double-fed wind driven generator of a wind turbine generator.
Background
In the prior art, safety, reliability and intellectualization are more and more important for modern wind turbines, and for early turbines, due to the fact that the technology is immature, certain defects exist, operation risks exist, and for the defects, technical improvement is needed to solve. The doubly-fed wind generator generally only monitors the temperature of components such as a bearing, a stator winding, an internal cavity of the generator and the like, and the temperature of the components can be directly fed back out of the running state of the unit. However, in actual operation, after the generator bearing is damaged, the bearing inner cover and the rotating shaft directly rub against each other, and the current bearing temperature monitoring device cannot feed back in time, so that the generator is seriously failed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a safe, reliable and timely temperature monitoring device for the inner cover of the double-fed wind turbine bearing of a wind turbine generator, which can technically improve the early generator on a tower, monitor the temperature of the inner cover of the generator bearing in real time and avoid serious faults caused by friction between the inner cover and a rotating shaft.
In order to achieve the purpose, the technical scheme provided by the utility model is as follows: the utility model provides a double-fed aerogenerator bearing inner cup temperature monitoring devices of wind turbine generator system, includes temperature probe and temperature element, wherein, the front end of temperature probe passes double-fed aerogenerator's frame curb plate and extends toward the bearing inner cup direction, and its rear end is fixed on this frame curb plate, temperature element installs the front end at the temperature probe to contact the hole department of bearing inner cup, on the cabin cabinet control module of wind turbine generator system was received to temperature element's lead wire, cooperation wind turbine generator system's control system realized the real-time supervision and the protection of highest temperature of generator bearing inner cup temperature.
Compared with the prior art, the utility model has the following advantages and beneficial effects:
the utility model designs a safe, reliable and timely-feedback bearing inner cover temperature monitoring device, technically improves an early unit on a tower, monitors the temperature of the bearing inner cover of a generator in real time, and is matched with a control system of an upper unit to stop the unit in time when the temperature of the bearing inner cover exceeds a certain value so as to avoid serious faults caused by friction between the bearing inner cover and a rotating shaft.
