Description
Technical field
The utility model relates to technical field of wind power generation, relates in particular to a kind of wind turbine generator cable protective device.
Background technology
Along with human environmental consciousness with to the raising of clean energy resource demand, wind energy has received extensive attention as a kind of regenerative resource.In recent years, various countries constantly strengthen the development and utilization of wind energy, and wind power technology is flourish.Because wind direction and wind speed are always in continuous variation; Therefore, in order to improve utilization ratio of wind energy, just need guarantee that engine rooms of wind power generators is down with the wind positive all the time; People have set up yaw system in wind-driven generator for this reason; It can constantly adjust the engine rooms of wind power generators direction according to the variation of wind direction, and is down with the wind positive all the time to guarantee it, thereby farthest utilizes wind energy.
In the driftage process, the cabin so just makes and reverses from the cabin through the vertical power cable generation when going off course to ground of pylon along with the variation of wind direction is constantly rotated.In order to make cable the time can reverse and can not turn round cable or sustain damage because of reversing to produce along with the rotation in cabin in driftage, require bunch of cables freely to rotate, therefore need one to grow a section cable and be in overhang.Present way is, cable get into from the cabin behind the pylon with pylon with several meters of axle sag or tens meters, then carry out the transition to Ta Bishang through transition apparatus, extend to ground along the fixture on the tower wall more always.
Yet pylon and cabin swing back and forth under wind, and the height of general pylon is all more than 50 meters, thereby make the section of dangling cable because of acutely swing in pylon, even collide pylon and damage cable.For fear of the significantly swing of the cable that dangles, the corresponding position of the cable that in pylon, dangles usually is provided with the swing displacement that a series of cable back-up rings limit cable.Though this method has limited the swing displacement of the cable that dangles, between bunch of cables and cable back-up ring, still there are collision and friction, this still causes wearing and tearing to cable easily.
Common a solution is at present; Near each cable back-up ring; Two semicircle shape thin-walled materials with a bit of rubber or plastic type material matter are coated on the bunch of cables; Contact with the direct of cable back-up ring with isolated cable, however the landing and lose effectiveness after a period of time of working easily of this structure.
Another kind of common solution is; Two semicircle shape thin-walled materials of very long one section rubber or plastic type material matter are coated on the bunch of cables; And make this thin-walled material pass set a series of cable back-up rings; Thereby in the upper end of this thin-walled material it is fixed and to limit it in axial moving, to prevent its downslide.In practical application, though this method can effectively reduce the collision between cable back-up ring and the bunch of cables and rub to the infringement of cable, it need use more material, thereby causes waste.
