Abstract
The utility model discloses a special bus duct for wind power. The special bus duct comprises a multi-phase bus tube conductor (3), an insulation supporter (5), a fixing piece (6), a conductor flexible connector (7) and a shell flexible connector (8), wherein the multi-phase bus tube conductor (3) is hollow; the end part of the multi-phase bus tube conductor is pressed into a string nose shape. The special bus duct for wind power uses the characteristics of small alternating current skin effect coefficient and better electrical conductivity of the hollow tube conductor to minimize the appearance of a heavy current bus duct conductor; meanwhile, a tube conductor structure has higher structure strength and rigidity than that of a rectangle conductor structure; therefore, the stability of the bus duct conductor and an insulation structure of the bus duct conductor under an irregular pneumatic environment can be guaranteed. As a common rigid connecting structure at the connection part of the bus duct is changed into a flexible connecting structure, the capacity of the bus duct structure for adapting to a wind turbine tower structure and bearing irregular pneumatic power is improved. The special bus duct for wind power can be applied to the power energy output loops of various high capacity grid-connected wind power generators.
Description
Technical field
The utility model belongs to MW class grid type technical field of wind power generation, is specifically related to a kind of wind-powered electricity generation special mother wire casing.
Background technology
The application and the development prospect of present domestic new forms of energy wind turbine generator are wide, wherein MW class grid type wind-driven generator pool-size also tends to maximize, by bigger 2.0～3.5MW even the 5MW of single-machine capacity 1.2～1.5MW trend, the output current that has brought separate unit unit (output voltage of most blower fans is low pressure 690V) thus by 1000A～1600A to higher 2000A～3000A, it is more unfavorable to bring for thus the laying installation of original wind-powered electricity generation outlet cable, and the drawback on electric property also manifests gradually.Under this background, insulation power transmission busbar by conventional busbar assembling progressively is applied to wind-force wind-powered electricity generation field, because the fickle randomness of environment particularity, wind-force of large-scale wind electricity unit installation site, make the application of power transmission busbar in the wind-powered electricity generation field of conventional busbar assembling produce many drawbacks, be in particular in following several respects:
