Abstract

The invention provides a device for monitoring the axis temperature of a wind turbine generator. The device is composed of a main bearing shaft, a collecting device and a PC portable machine that areconnected successively. A temperature sensor is arranged at the main bearing shaft. An A/D converter, a data processing module and a wifi interface are arranged in the collecting device. A wireless network card, an analysis program, a display device, and a data storage unit are arranged in the PC portable machine. The device is used simply and is carried conveniently; and defects of complicated mounting and poor portability of the original monitoring testing device are overcome. Data collection is performed by means of WIFI communication, so that entrance of the operator in a fan tower is avoided. The NI-9213 measuring set collection device is employed and is provided with 16 thermocouple channels, 250-Vrm ground-grounded safety isolation channel, and a 24-bit ADC; and the sensitivity is measured at the highest temperature of 0.02 DEG C.

Description

technical field [0001] The invention relates to a device and method for monitoring the temperature of a shaft system of a wind turbine, and belongs to the design field of temperature devices for the shaft system of a motor group. Background technique [0002] The wind turbine is a large flexible structure that is subjected to transient aerodynamic excitation. The shafting of the wind turbine mainly transmits the energy of the fan to the generator. Under the action of complex dynamic loads, its transmission torsion performance directly affects the size of the transmitted power, working life and Overload protection performance, etc. The wind turbine main shaft temperature monitoring device can detect the failure point of the shaft system in time, which is convenient for the on-site maintenance personnel to take emergency measures to avoid and reduce the spread of faults; after monitoring the temperature of the wind turbine main shaft, it can prompt the abnormal state of each b...
