A wind turbine (1) having a power generation assembly (5) and a control device (9) for controlling the power generation assembly (5), the power generation assembly (5) comprising a generator (6), at least one converter (7) connected to the generator (6) and an overheat detection device (10), characterized in that the converter (7) is connected to the generator (6) and the overheat detection device (10) is connected to the control device (9). The overheat detection device (10) comprises:-at least two temperature sensing elements (12) at different locations of the power generation component (5), where the temperature sensing elements (12) are connected in series along a signal line (14) to provide a common sensor signal and each adapted to indicate in the common sensor signal that a respective critical temperature is exceeded at their location, and-a detection unit (15) for evaluating said common sensor signal, said detection unit (15) being connected to said signal line (14). 一种风力涡轮机（1），具有发电组件（5）和用于控制所述发电组件（5）
