Torsion cable protection device, usage method of torsion cable protection device, and wind generating set

Abstract

Embodiments of the invention provide a torsion cable protection device, a usage method of the torsion cable protection device, and a wind generating set. The torsion cable protection device comprises cable clamp blocks and a cable isolation plate. Each cable clamp block comprise a first clamp block and a second clamp block which are connected to form a cylindrical structure with a through hole used for clamping the cable in the middle. The cable isolation plate is formed by splicing more than two splitter plates and grooves are arranged in the connection surfaces of the splitter plates. The cable clamp blocks are fixedly connected on the cable isolation plate, and the cylindrical structure formed by each cable clamp block is vertically aligned to a separation hole in the cable isolation plate. The beneficial effects are that the cables are clamped and fixed by the cable clamp blocks, the cable isolation plate formed by splicing is used to fix the cable clamp blocks, the separation holes in the cable isolation plate separates the cables, so that the heat radiation of the cables is ensured, and the problem that the cables are twisted and coiled when the cabin rotates due to change in the wind direction is solved.

Description

Technical field [0001] The present invention relates to the technical field of wind power generation equipment, in particular to a twisted cable protection device, a method of using the twisted cable protection device, and a wind power generating set. Background technique [0002] The generators of wind turbines are generally placed in the nacelle on the top of the tower (usually located at an altitude of tens of meters or even hundreds of meters). The electricity generated by the generators needs to be transmitted to the ground through cables to facilitate the collection of electrical energy and the transmission to the grid For transportation, the cables are laid vertically downward from the nacelle along the direction of gravity inside the tower. [0003] In the process of generating electricity, the blades of the wind turbine generator need to be set up against the wind. When the wind direction changes, the blades and the nacelle need to rotate with the change of the wind direct...
