Power cable basket structure for large-sized wind generating set

Abstract

In a traditional wind generating set, power cables from a cabin part to a tower part are fixedly arranged on a U-shaped hanging board on a channel steel beam at the bottom part a cabin by mainly adopting cable sleeve net structures, and as the power cables are respectively bound by cable sleeve nets to form prints, and part of power cables are insufficiently centered, the power cables can be rubbed with a center bushing of a tower top platform during a skewing process, cable sheaths can be easily abraded, and great potential safety hazards are brought. The invention provides a power cable basket structure for a large-sized wind generating set. The power cable basket structure for the large-sized wind generating set comprises the U-shaped hanging board, a round basket, three supports and bolts, wherein the U-shaped hanging board is welded on the channel steel beam at the bottom part of the cabin, and the three supports are connected with the basket and the U-shaped hanging board. Through adopting such the power cable basket structure, the power cables are stressed by the inner wall of the round basket without the cable sleeve nets, and meanwhile, the round basket also plays a role of guiding the cables so as to ensure the power cables to be fully centered when reaching a tower from the cabin, and therefore, the power cable sheaths are protected from abrasion during the skewing process, and the safety of the wind generating set is improved.

Description

Technical field: [0001] The invention relates to a power cable hanging basket structure for a large-scale wind power generating set. technical background: [0002] In large-scale wind turbines, there are a large number of power cables between the nacelle and the tower. Since the wind turbine needs to yaw, the cables must enter the center of the tower from the cable racks in the middle and both sides respectively. [0003] In the existing wind power generating set, when the power cable enters the tower from the nacelle, the cable netting structure is mainly used to fix the power cable on the U-shaped hanging plate on the channel steel beam at the bottom of the nacelle, and the cable netting bears the weight of the power cable. Due to the large tension force of the power cable by the cable netting, the outer skin of the cable will produce deep scratches under long-term force, and the power cables on both sides are not aligned. During the yaw process, the center of the power ca...
