Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a cable installation structure for a wind turbine set. Background Art

[0002] Converting the kinetic energy of wind into mechanical kinetic energy, and then converting mechanical energy into electrical kinetic energy, this is wind power generation. When a wind turbine is generating electricity, the output frequency must be kept constant, which is very necessary for both wind turbine grid-connected power generation and wind-solar complementary power generation. To ensure the constant frequency of wind power, one way is to ensure the constant speed of the generator, that is, constant speed and constant frequency operation. Because the generator is driven by the wind turbine through a transmission device, this method undoubtedly requires a constant speed of the wind turbine, which will affect the conversion efficiency of wind energy; another way is to change the generator speed with the wind speed, and use other means to ensure the constant frequency of the output electricity, that is, variable speed constant frequency operation. Wind turbines need to use cables to transmit current, and the cables must provide fixed support for multiple cables when transmitting current.

[0003] After searching, the published patent number CN210859072U mentioned a cable fixing device for a wind turbine generator set, including a wind turbine generator set, a sliding plate is arranged above the wind turbine generator set, a plurality of wire trays are arranged in the sliding groove of the sliding plate, a chuck is arranged above the wire tray, two symmetrically arranged sub-cable slots are opened below the chuck, two symmetrically arranged mother-cable slots are opened on the upper surface of the wire tray and located directly below the sub-cable slots, and the arc surface positions of the sub-cable slots and the mother-cable slots are fixedly connected with rubber pads, a first threaded hole is opened at the middle position of both sides of the upper surface of the wire tray, a butterfly bolt is rotatably connected through the upper surface of the chuck, and the butterfly bolt is threadedly connected with the first threaded hole. This product can effectively classify and fix the cables on the side of the wind turbine generator, making the wiring more stable and firm, making the wiring more tidy, and convenient for maintenance, and also reducing the occurrence of short circuit accidents.

[0004] Although the above solution solves the problem raised in the background art, it still has the following shortcomings: when the user rotates the butterfly bolt to fix the cable, the fixing effect is poor, resulting in poor practicality. Utility Model Content
