However, further studies have shown that although the above-mentioned existing methods can improve the strength of the machine base to a certain extent and prevent it from seriously deforming, it will also significantly increase the volume and weight of the whole machine at the same time, resulting in increased manufacturing costs and inconvenient use. and other issues; in particular, they did not take into account the adverse effects of electromagnetic force on the frame and stator during the power generation process, so the improvement of the tensile strength of the frame in practical applications is limited

The invention discloses a stator-deformation-resistant horizontal-axis large-sized wind turbine. The fixed part of a generating set of the wind turbine comprises an enclosure, a stator frame, a stator iron core, a stator winding, an end cover and the like. Flange faces are arranged at the upper end of the enclosure, the lower end of the enclosure, the upper end of the stator frame and the lower end of the stator frame and the upper end of the enclosure and the lower end of the enclosure are connected with the upper end of the stator frame and the lower end of the stator frame respectively through a plurality of connecting bolts which penetrate through the flange faces. In addition, a plurality of double-end studs are further evenly arranged between the enclosure and the stator frame in the circumferential direction of the enclosure, one end of each double-end stud penetrates through the enclosure in the radial direction of the enclosure and is screwed on the stator frame through a threaded structure, and the other end of each double-end stud is locked on the enclosure through a nut and a gasket. By means of the stator-deformation-resistant horizontal-axis large-sized wind turbine, the problems that in an existing wind turbine, the size of a stator frame is large and the structure is heavy can be solved, the tensile strength of the stator frame is obviously enhanced and the stator frame is effectively prevented from deforming on various power generation occasions.
Description
technical field [0001] The invention belongs to the technical field of wind power generator equipment, and more specifically relates to a large horizontal axis wind power generator resistant to stator deformation. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy, and is mainly composed of blades, generator sets, mechanical components and electrical components. According to the different rotation axes, wind turbines can be divided into horizontal axis wind turbines and vertical axis wind turbines. At present, horizontal axis wind turbines occupy the mainstream position in the market. For example, for large horizontal axis wind turbines that can be connected to the grid, such as figure 2 As exemplarily shown in , it includes a left and right opposite hub 11 and a nacelle 12. A plurality of blades (not shown in the figure) whose rotating shafts are perpendicular to the blades are arranged on the circumference of the hub ...
