Wind Turbine Cabin Structure With Side-Mounted Box Transformer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The placement of the power transformation structure at the rear of the cabin in wind turbine generator sets leads to increased vibration and reduced stability due to the lengthening of the rear bottom frame, which complicates manufacturing and transportation.
Innovation Solution
The cabin structure incorporates a box transformer unit and bracket positioned at the side end of the cabin body, connected to the main frame, reducing the cabin's size in the first direction, offsetting the center of gravity towards the axial direction, and optimizing the wiring path of transmission cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the power transformation structure is placed at the rear of the cabin, then the power transformation function is achieved, but the cabin size in the first direction increases and vibration amplitude increases
Solution Approach 1:
The patent relocates the box transformer structure from the rear end (first direction) to the side end (second direction) of the cabin body, utilizing a different spatial dimension. This dimensional shift reduces the cabin's length in the first direction while accommodating the power transformation function at the side, thereby resolving the contradiction between manufacturing ease and cabin size.
2Ease of manufacture
If the power transformation structure is placed at the rear of the cabin, then the power transformation function is achieved, but the vibration amplitude increases and stability decreases
Solution Approach 1:
By moving the box transformer structure to the side end of the cabin body in the second direction, the patent changes the spatial arrangement from rear-mounted to side-mounted. This dimensional repositioning optimizes the center of gravity distribution and reduces vibration amplitude, thereby improving cabin stability while maintaining the power transformation function.
3Strength
If the rear bottom frame is lengthened to support the power transformation structure, then the power transformation structure is supported, but the vibration of the entire cabin is aggravated
Solution Approach 1:
Instead of lengthening the rear bottom frame in the first direction to support the power transformation structure, the patent positions the box transformer structure at the side end in the second direction. This dimensional shift eliminates the need for frame lengthening while maintaining support capability, and simultaneously reduces cabin vibration by optimizing the mass distribution and center of gravity position.
4Stability of the object's composition
If the box transformer structure is positioned at the side end, then the center of gravity is offset towards the axial direction, but the wiring path optimization is required
Solution Approach 1:
The patent positions the box transformer structure at the side end of the cabin body in the second direction, which offsets the center of gravity toward the axial direction and improves stability. The wiring path is optimized by routing cables along the side configuration, reducing the complexity compared to rear-mounted arrangements by shortening cable lengths and simplifying the routing path.
