Problems solved by technology

These two methods are mainly due to the mechanical friction of the parts, which will cause mechanical friction, low sensitivity, and short life.
[0004] At the same time, the wind turbine rotates for a long time and many times, coupled with the wear of the wind turbine shaft and bearings, it is inevitable that the wind turbine rotor will have a slight inclination angle that deviates from the designed elevation angle, which will not only affect the accuracy of cable untwisting, but also Affect power generation efficiency, resulting in a reduction in power generation

Description

technical field [0001] The invention relates to the field of wind power machinery in the power industry, in particular to an uncable system and an uncable method in a wind power generating set. technical background [0002] At present, energy is the basic element of human existence and the main material basis of national economic development. Due to the depletion of fossil resources and the increasing concern of human beings on the deterioration of the global environment, wind power technology has also developed rapidly. In the natural environment, because the direction of the wind often changes, in order to make full use of the wind energy, the wind turbine is usually designed to automatically adjust the windward direction. When the nacelle yaw of the wind turbine reaches a certain number of turns, this will cause the cable Winding, if there are too many winding circles, exceeding the specified value, that is, the twisted cable will cause damage to the cable. Just need un...
