Description

Technical Field

[0001] The utility model belongs to the field of wind power generation, and in particular relates to a cable fixing frame for nacelle suspension of a wind power generator set. Background Art

[0002] As a vital component of renewable energy generation, wind turbines consist primarily of key components such as a box-type transformer, tower, nacelle, and blades. The wind turbine's generator, housed in the nacelle at the top of the tower, converts wind energy into electricity. This energy is then transmitted to the base of the tower via cables laid inside the tower. The voltage is then boosted by a box-type transformer at the base before being connected to the grid for use.

[0003] During wind turbine operation, the nacelle needs to constantly yaw to maintain its orientation toward the wind, maximizing power generation efficiency. However, because the tower is fixed to the foundation, the nacelle's rotation requires the nacelle cables to rotate with it. To prevent the cables from twisting during rotation, the nacelle cables are typically suspended at the center of the tower's top, then allowed to droop naturally for a distance before being laid along the tower's inner wall to the base. This allows the cable section that naturally droops from the nacelle to rotate with the nacelle, while monitoring the maximum torsion angle to prevent cable damage.

[0004] In current practical applications, wind turbines typically have high output power, requiring numerous and heavy cables for power transmission. To protect these cables from damage during suspension, a cable-pulling suspension mesh is typically used to suspend the cables from suspension points at the bottom of the nacelle. Due to the heavy weight of the cables, prolonged use of the wire mesh can damage them, and some cables can even be damaged by the mesh. This not only shortens the service life of the cables but can also pose a safety hazard to the normal operation of the wind turbine. Furthermore, the mesh installation process is relatively complex, requiring insertion from the cable head. Once damaged, replacement is a complex undertaking and presents numerous defects.
