The panel is composed of a front supporting panel, a back supporting panel and a u type panel three parts, and the panel parts are welded together, the bottom plates include a front bottom plate, a central bottom plate; the lateral plates include a front end board, a front side board, a back end board and a back side board, and all the parts are welded into a whole; the panel, the bottom plate and the lateral board are all provided with mounting holes or fabrication holes.

Description

1. Technical field: [0001] The invention relates to a frame of a 1.5 megawatt (and above) wind power generating set and a preparation method thereof. 2. Background technology: [0002] Wind energy is one of the most commercially potential and most dynamic renewable energy sources. It is clean, low-cost, and inexhaustible. Wind power has the advantages of large growth space for installed capacity, rapid cost reduction, safety, and energy never being exhausted. Wind power can effectively alleviate air pollution, water pollution and global warming while providing a stable power supply for economic growth. [0003] The barriers to entry in the wind power equipment industry are relatively high. Wind power equipment mainly includes complete machine assembly, motors, blades, tower bases, racks, etc., and the technology is very complicated. Wind electrodes are the most important thing about the stability of the unit's operation. Wind turbines need to operate reliably in the field ...
