Saddle structure with cable twisting limiting function

Abstract

The invention discloses a saddle structure with a cable twisting limiting function. The structure comprises a transition saddle, a limiting swing arm and a first cable separation assembly, the transition saddle and the limiting swing arm are hinged to the two ends of the limiting swing arm respectively, so the first cable separation assembly swings only in the vertical direction. The transition saddle comprises a support and a cable bridge used for carrying a cable, the support is installed on a tower drum, the limiting swing arm is hinged to the support, and a plurality of branching holes areformed in the first cable separation assembly. The suspension cable is isolated and clamped by the cable separation assembly, so that the cables are prevented from being wound and collided during yawing, and damage and electric leakage caused by mutual friction of cable sheaths are avoided. When the cable is arranged, a three-phase one-group arrangement mode is adopted, electromagnetic interference is reduced, current transmission quality is ensured, the limiting swing arm ensures that the cable only moves up and down and does not twist or swing, and stress of the cable is effectively reducedwhile abrasion of the cable is further avoided.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a saddle structure with a twist and limit function. Background technique [0002] The structure of the wind turbine is complex, and there are many risk control points. Taking the tower cable as an example, during the wind turbine yaw process, the upper freely hanging cable twists with the wind turbine yaw, and the lower cable is fixed to the inner wall of the tower by a cable clamp. , When the conventional design of the rotating section and the fixed section transition, the cables are messy, the torsion is serious, the cables wear each other, and a fire is caused in severe cases. In addition, due to the entanglement of the cables, the electromagnetic interference is serious, which affects the quality of current transmission. Contents of the invention [0003] In view of this, the problem to be solved by the present invention is to provide a saddle structure with ...
