Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a cable construction device for a wind power generator. Background Art

[0002] With the increasing consumption of non-renewable resources such as oil and natural gas, the development and utilization of renewable energy has gradually developed. Among them, wind power generation is a power generation method that uses wind energy to convert into electrical energy. By installing wind turbines, wind energy is converted into mechanical energy, and then the mechanical energy is converted into electrical energy through generators. Wind power generation has the advantages of being environmentally friendly, renewable, and clean, and is widely regarded as a clean energy that can replace traditional thermal power generation.

[0003] The working principle of wind power generation is that the wind drives the wind wheel to rotate. The wind wheel is connected to the generator. The rotor of the generator rotates to generate current. The low-voltage electrical energy output by the generator is converted into high-voltage electrical energy through a transformer and finally input into the power grid for power supply.

[0004] When installing and removing cables for wind power generation, manual operation is generally used. For some large wind power generation equipment, the cables are relatively thick and heavy, and manual installation or removal is quite inconvenient. In addition, the cables are easily damaged during the manual dragging construction process, so a cable construction device needs to be designed. Utility Model Content
