Wind generating set and twisted cable protection system thereof

Abstract

The invention discloses a twisted cable protection system, which is used for protecting a cable in a tower drum. The twisted cable protection system comprises a connecting rope, a separation disc, a limiting swing bracket and a swing arm mechanism. The connecting rope is fixed to the cabin and extends into the tower drum, the connecting rope is connected with at least two separation discs in series in the axial direction of the separation discs, and a plurality of containing holes penetrating through the separation discs are formed in the separation discs. The swing limiting support is arranged outside the separation disc in a sleeving mode and used for limiting transverse swing, the swing arm mechanism is connected with the separation disc at the bottom, and the swing arm mechanism can swing under pulling of the connecting rope and limit autorotation of the separation disc connected with the swing arm mechanism. The invention further discloses a wind generating set which comprises the twisted cable protection system. According to the wind generating set and the twisted cable protection system thereof, the positions of the cables can be restrained, the multiple cables are prevented from being twisted together in the yawing process, collision and abrasion between the power cables are reduced, the stress of the cables can be reduced, the transverse movement effect of the cables is limited, and the cables are prevented from being twisted, wound and bundled as much as possible.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a wind power generating set and a twisted cable protection system thereof. Background technique [0002] A wind turbine mainly includes a tower, a wind wheel, a nacelle, a main shaft, a yaw system, a gearbox, a high-speed shaft, a generator, and a control system, among which the yaw system, the gearbox, and the generator are located in the nacelle. The technical principle of the wind turbine is that the wind wheel converts wind energy into rotational mechanical energy, the main shaft transmits the mechanical energy of the wind wheel to the gearbox, and the gearbox converts the low-speed mechanical energy of the main shaft into high-speed mechanical energy suitable for the generator and passes it through the high-speed shaft. Input to the generator, which is used to convert mechanical energy into electrical energy. [0003] At present, the technology of wind turbines is becomi...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to provide a wind turbine and its twisted cable protection system for the problem that the cables are prone to entanglement during the yaw operation of the unit.
