Abstract
The invention discloses a wind power generation low-pressure bus duct system and belongs to the technical field of wind power generation devices. The wind power generation low-pressure bus duct system comprises straight-through bus ducts and a connecting unit. The two adjacent straight-through bus ducts are connected through the connecting unit. The connecting unit comprises an expansion unit and connectors connected with the two sides of the expansion unit respectively. The expansion unit comprises a frame defined by an upper cover plate, a lower cover plate, a left side plate and a right side plate, and a conductor component. The conductor component is fixedly connected with the left side plate and the right side plate, and a space enough for displacement, stretching and retracting is reserved among the conductor component, the upper cover plate and the lower cover plate. The conductor component specifically comprises conductor strips and insulation spacer blocks, wherein each insulation spacer block is used for connecting every two adjacent conductor strips, and conductor blocks formed by the conductor strips and the insulation spacer blocks are clamped with irregularly-shaped clamping plates arranged parallel to the conductor strips. A part of stretching stress is eliminated through the stretching, retracting and expansion effect between the conductor component and the frame. Stretching and distortion force generated by tower cylinder swing, of the conductor strips in the system operation process can be well eliminated due to the fact that the conductor strips are made of metal which is flexible in stretching, retracting and torsion.
