Novel cable protection system for twisted cable for wind electricity

Abstract

The invention discloses a novel cable protection system for a twisted cable for wind electricity. The novel cable protection system comprises a twisted cable hoop support, a twisted cable hoop support hole and a twisted cable jacket used for fixing the twisted cable for wind electricity, wherein the twisted cable hoop support hole is formed in the twisted cable hoop support; an inserted anti-collision ring is embedded into the twisted cable hoop support hole; a rubber layer is stuck in the anti-collision ring; the outer diameter of the twisted cable jacket is smaller than the inner diameter of the twisted cable hoop support hole; the twisted cable jacket is located in the twisted cable hoop support hole; the outer wall of the twisted cable jacket is in contact with the rubber layer; the height of the twisted cable jacket is greater than that of the twisted cable hoop support hole; the anti-collision ring and the rubber layer are both of split structures. The invention provides the novel cable protection system for the twisted cable for wind electricity, which has the advantages of good wear resistance, convenience for installation, maintenance and operation, and good safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of wind power generating sets, and relates to a twisted cable protection system for wind power. Background technique [0002] When the wind turbine yaws, the cables will be twisted. Regardless of whether the converter is located in the nacelle or under the tower, there must be power cables, part of the unit power supply cables and control cables connected to the upper and lower towers. The number of cables required increases and the specifications become larger. Generally, the connection cables between the upper tower and the lower tower are vertically suspended from the end of the bridge frame in the engine room to the saddle twisted cable platform, and the length is about 9-12m. When the wind direction changes or the wind speed is high, the unit yaws or the unit shakes greatly, twisting the cable will cause the cable to shake and the length of the cable to change. Over time, it will cause cable wear, affec...
