Abstract

The invention relates to a permanent magnetic transmission coupler of a wind generating set and a generator rotor temperature measuring method. According to the method, wireless temperature collection devices are respectively embedded inside a permanent magnetic transmission mechanism coupler and a generator rotor, a temperature signal is received through a wireless temperature collection device which is arranged on a ground operating platform, and the real temperature of the coupler and the rotor in the transmission working process can be measured in real time.

Description

technical field [0001] The invention relates to a permanent magnet transmission coupling of a wind power generating set and a method for measuring the temperature of a generator rotor. Background technique [0002] At present, most of the coupling mechanisms widely used in the industry are rigid connections. If the two shafts are not strictly aligned, vibration and noise will be generated and the life of the equipment will be shortened. The permanent magnetic coupler realizes the flexible connection between the input shaft and the output shaft through the air gap. Since there is no mechanical connection, the friction loss is very small. There will be a high starting current during the starting process of the motor, especially in the case of a large load. In order to avoid the danger caused by excessive current during the starting process and reduce the impact on the transmission mechanism, soft starting technology is introduced to realize the system. Smooth start. This kin...
