Abstract
The invention discloses a two-end driving type wind generator unit. A wind generator unit with a new structure has an obvious appearance feature that the back part of a cabin is additionally provided with a wind wheel, and has a typical structure that a front wind wheel with three blades, a back wind wheel with three blades and a generator are arranged in a coaxial way, wherein the generator adopts a two-end direct driving type alternating current permanent magnetic synchronous generator. By adopting the coaxial arrangement scheme, the two-end driving type wind generator unit has the advantages that the structure is compact, the occupied space is small, the layout is convenient, the mechanical loss is small, the efficiency is high, the reliability is high, and the use cost is low.
Description
Technical field
The invention belongs to wind-driven generator professional domain, be specifically related to wind generating set structure, particularly the arrangement of wind wheel blade and the linkage structure with generator thereof.
Background technique
Wind-powered electricity generation be generally acknowledge in the world closest to one of commercialization, renewable energy technologies that the market competitiveness is the strongest, and Wind turbines is in the application all the wind power generating set that wind wheel blade is arranged in one end.Artificer considers in line with improving wind energy utilization efficiency, releases the wind power generating set that wind wheel blade is arranged at two ends.
Summary of the invention
Two ends drive wind power generating set, and be a kind of wind power generating set of brand new, its remarkable external appearance characteristic is exactly add a wind wheel behind cabin; Its typical structure is front end wind wheel (3 blade), rear end wind wheel (3 blade) and two ends directly driving type alternating-current synchronous generator coaxle.Owing to taking coaxially arranged mode, set structure is compact, takes up space little, arrangement convenience, and mechanical loss is little, and efficiency is high, and reliability is high.
Two ends drive other structure choice of wind power generating set visible " Figure of description ".
The two ends directly driving type alternating-current synchronous generator that unit adopts, its axle two ends are all protruding, are significantly different from other direct-driving type wind power generation machine.
