Abstract
The utility model discloses a hydraulic generator rotor coil temperature-detecting device. Each coil assembly of a generator rotor is provided with a temperature sensor. The output signal of the temperature sensor is joined to a data acquisition recording instrument. The data acquisition recording instrument receives data from a wireless data transfer module arranged on the generator rotor through an industrial bus. Another wireless data transfer module arranged on a generator stator is connected with an upper computer. Data transfer between the upper computer and the data acquisition recording instrument is completed through wireless data communication between the two wireless data transfer modules. The upper computer records the temperatures of each coil assembly of the generator rotor at any moment on line, which provides scientific basis for safe operation and preventive maintenance of a set and preventing accidents as well as important reference for structural design of the set.
