Embodiment Construction
[0026] Embodiments of the invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.
[0027] like figure 1 As shown, the wind turbine according to the embodiment of the present invention includes a plurality of stator fins 1 , an upper bracket 2 and a lower bracket 3 evenly distributed around the stator of the wind turbine, and each stator fin 1 is detachably mounted on The upper bracket 2 is located between the upper bracket 2 and the lower bracket 3 , and the lower bracket 3 is formed with a through hole 4 .
[0028] Specifically, the stator fins 1 can be connected to the inner side (ie, the side facing the base 5 ) of the upper bracket 2 by bolting or the like. The lower bracket 3 and the upper bracket 2 form a space for disposing the stator fins 1, and have through holes 4 at positions corresponding to the stator fins 1 of the lower bracket 3, such as figure 1 As shown, the through h...

The invention provides a replacement method and a replacement device for a stator heat sink of a wind turbine. The method for replacing the stator heat sink includes: rotating the stator heat sink around the first end of the stator heat sink, so that the stator heat sink is relative to the through hole. The plane where it is located is inclined, and the second end of the stator heat sink opposite to the first end is located at the through hole; the first end of the stator heat sink is translated a predetermined distance, and the second end is kept at the through hole. ; Move the stator heat sink away from the upper bracket, and during the movement, adjust the inclination angle of the stator heat sink relative to the plane where the through hole is located, so that the stator heat sink passes through the through hole. The replacement method and the replacement device for the stator fins of the wind turbine according to the present invention can reduce the work intensity, improve the replacement efficiency, and reduce the maintenance cost.
Description
technical field [0001] The invention relates to a replacement method and a replacement device for a stator heat sink of a wind power generating set. Background technique [0002] As the single unit capacity of wind turbines tends to be larger, the size and weight of large components of the unit are also gradually increasing. For the generator of the wind turbine, it is necessary to increase the corresponding windings, coils and magnetic steel to bring more power generation, but at the same time, the requirements of the generator on the cooling loop control system are becoming more and more stringent , the traditional generator air-cooled environmental control system cannot meet the heat dissipation effect required by large-capacity generators. Therefore, more and more high-power wind turbines have begun to use water-cooled environmental control system solutions to ensure that the generator does not work. The entire generator fails due to damage to internal components due to...
