    Abstract: A yaw sensor for a wind turbine is described. The yaw sensor comprises a rotary switch, configured to be coupled to a yaw drive gearbox of a wind turbine nacelle, the rotary switch being operable to activate and deactivate an electrical contact in dependence on an amount of yaw rotation of the nacelle relative to a start position. The electrical contact is active at a plurality of first yaw rotation ranges with respect to the start position, and inactive at a plurality of second yaw rotation ranges with respect to the start position, the first and second yaw rotation ranges being interleaved, at least some of the first yaw rotation ranges having different lengths from each other and/or at least some of the second yaw rotation ranges having different lengths from each other. The electrical contact generates an electrical signal when active.

    Abstract translation: 描述了用于风力涡轮机的偏航传感器。 所述偏航传感器包括旋转开关，所述旋转开关被配置为联接到风力涡轮机机舱的偏航驱动齿轮箱，所述旋转开关可操作以根据所述机舱的偏航旋转量相对于起始点的启动和停用电触点 位置。 电触点在相对于起始位置的多个第一偏航旋转范围处起作用，并且相对于起始位置在多个第二偏航旋转范围处不起作用，第一和第二偏航旋转范围被交错，至少一些 所述第一偏航旋转区域具有彼此不同的长度和/或所述第二偏航旋转区域中的至少一些具有彼此不同的长度。 电触点在激活时产生电信号。
