Overtemperature prevention device for brake of wind generating set

The invention discloses a wind generating set brake overtemperature prevention device which comprises a fixing assembly comprising a fixing plate and a fixing support, a driving assembly which is connected with the center of the fixing plate in a penetrating mode and comprises a first shaft and a second shaft, and a temperature measuring assembly which is arranged on one side of the driving assembly and comprises a third shaft and a temperature sensor. Through cooperation of the fixing assembly, the driving assembly and the temperature measuring assembly, the temperature of the brake of the wind generating set can be monitored more accurately, early warning is provided before the temperature of the brake is too high due to too long braking time, meanwhile, abrasion in the initial stage of braking is avoided, and the service time of the device is prolonged. 本发明公开了一种风力发电机组制动器防超温装置，其中有固定组件，包括固定板和固定支架，驱动组件，贯穿连接所述固定板中心，包括一号轴和二号轴，测温组件，设置于所述驱动组件一侧，包括三号轴和温度传感器。本发明通过固定组件、驱动组件、测温组件之间的配合，能够更准确的监测风力发电机组制动器的温度，并在刹车时间过长导致制
