However, in the prior art, the anti-wear means of cables all have common shortcomings. First, when laying multiple cables, all cables are wrapped in the same protective material, and the cables cannot be separated. If the cables need to be distinguished, repeated operations are required. , such as laying multiple pipes or winding wear-resistant strips on the cables one by one; the second is that the cables cannot be fixed, easily slipped or wound inside

Embodiment 1
[0028] During installation, the fixed card 9 is put together into a ring structure through the inner ring wedge groove 10 and the inner ring wedge block 11, then the ring 12 is placed through the center cable, and fixed by the fixed plate 13, and then the fixed block 6 is passed through the outer ring. The ring wedge 7 and the outer ring wedge groove 8 are assembled into the outer cable ring 1, and finally the long bolt 5 runs through the outer cable ring 1 and the inner cable bolt 2 in sequence and is fixed by a nut.
[0029] When fixing the cable in the central cable cavity 4, the fixing card 9 can be assembled into a "C" shape structure through the inner ring wedge groove 10 and the inner ring wedge block 11, leaving a gap, and inserting the cable into the center cable cavity 4 from the gap In, install last fixed card 9 again.
[0030] When installing cables to the outer cable cavity 3, the fixed block 6 can be assembled into an arc-shaped structure through the outer ring w...

A cable separation protection device for a megawatt wind generating set torsion cable comprises an outer cable ring and an inner cable ring, wherein an outer cable cavity is formed between the inner ring side of the outer cable ring and the outer ring side of the inner cable ring, and a central cable cavity is formed in the inner ring side of the inner cable ring. A cable is arranged in each of the outer cable cavity and the central cable cavity, and the outer cable ring and the inner cable ring are fixedly connected through long bolts. The cable separation protection device has the beneficialeffects that a cable is fixed and prevented from slipping, so that the cable can be prevented from being worn. Meanwhile, the cable can be isolated and fixed. The cable separation protection device is flexible and convenient to use.
Description
technical field [0001] The invention relates to the field of cable accessory equipment for generator sets, in particular to a cable separation and protection device for twisted cables of megawatt wind power generator sets. Background technique [0002] The structure of the cable is generally a metal core wrapped with an insulating layer. The main function of the insulating layer is to prevent leakage. However, when the cable is used for a long time, due to wear and tear, the outer insulating layer of the cable will be damaged, posing a safety hazard. According to different cable laying environments, the prior art provides a variety of solutions, such as laying pipelines and running cables through the pipelines, wrapping the cables with strip-shaped wear-resistant materials outside the cables, and so on. However, in the prior art, the anti-wear means of cables all have common shortcomings. First, when laying multiple cables, all cables are wrapped in the same protective mater...
