Cable twist-preventing structure for cables of wind generating set, and wind driven generator

Abstract

The invention provides a cable twist-preventing structure for cables of a wind generating set, and a wind driven generator. The cable twist-preventing structure comprises a circular-ring-shaped current collecting guide rail and a current collecting slider; the circular-ring-shaped current collecting guide rail is arranged horizontally, and the current collecting slider is connected to the current collecting guide rail and capable of sliding along the current collecting guide rail; the cables in the wind generating set include a cabin cable arranged in a cabin and a tower barrel cable arranged in a tower barrel; the current collecting guide rail is connected with the cabin cable, while the current collecting slider is connected with the tower barrel cable. Alternatively, the current collecting guide rail is connected with the tower barrel cable, while the current collecting slider is connected with the cabin cable. By using the cable twist-preventing structure for the cables of the wind generating set, unlimited rotation of the cabin can be realized, and the adaptability to wind directions can be enhanced; meanwhile, a yaw angle detector and a yaw protector are not required, and therefore, not only is the manufacturing cost reduced, but also the reliability of the set during operation is enhanced.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to an anti-twist cable structure of a wind power generator cable and a wind power generator. Background technique [0002] The yaw system of the wind turbine, also known as the wind-facing device, is a part of the nacelle of the wind turbine. Its function is to quickly and smoothly align the wind direction when the direction of the wind speed vector changes, so that the impeller can obtain the maximum wind energy. [0003] Due to the limitation of the generator cable, the nacelle of the wind turbine can only yaw and face the wind within a certain angle range. Moreover, a yaw angle detection device and a yaw protection device need to be provided to limit the rotation of the nacelle, so as to prevent damage to the cables caused by excessive rotation of the nacelle. The adaptability of the wind turbine to the wind direction is greatly limited, and the cost is relatively ...
