Abstract

The embodiment of the invention provides a cable protection device and a wind generating set. The cable protection device comprises a fixing ring and a clamping part, wherein the fixing ring is provided with a through hole extending in the first direction, the fixing ring comprises an inner side face and an outer side face which are oppositely arranged in the radial direction, the outer side facecomprises two or more mounting faces, and the mounting faces comprise vertical axes; the clamping parts are arranged on the mounting faces, can at least deflect around the vertical axes, and are provided with at least one through hole penetrating in the first direction so that cables can be clamped in the through holes and deflect within the preset range around the vertical axes relative to the fixing ring. According to the cable protection device in the embodiment, the cables are fixed at intervals, the cables can deflect around the vertical axes on the mounting faces through the clamping parts and can also at least deflect within the preset range around the vertical axes, the problem that the cables are intertwined due to twisting can be effectively prevented, and meanwhile the heat dissipation effect of the power cables can be ensured.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a cable protection device and a wind power generating set. Background technique [0002] The generating power of wind turbines with horizontal axis is generally between 0.1MW and 10MW. The generator, rotating blades and nacelle of a wind turbine are placed on top of a tower and rotate as the wind changes direction. [0003] The power cable of the generator is arranged downward along the tower so that the electric energy of the wind turbine can be output along the cable to the ground equipment. When the nacelle rotates with the wind direction, the corner of the nacelle can reach 2-3 circles, so that the power cable will also be twisted accordingly. During the twisting process of the power cables, because the twist angle is too large, the power cables are entangled with each other, resulting in a decrease in the heat dissipation effect of the power cables.
