Prefabricated Busbar Transposition Device with Folded Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transposition methods for prefabricated electrical busbars, particularly for power supplies at the end of the line, result in high lead times and production costs due to the need for custom solutions for each case, leading to large volumes and inefficiencies.
Innovation Solution
A transposition device for prefabricated electrical busbars that incorporates conductive bridges with a U-shaped cross-section, allowing for the inversion of bar portions within a compact design, facilitating easy integration into power lines and providing improved resistance to short circuits by using plated bar portions with insulating material and screws/nuts for secure connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transposition is carried out on power supplies located at the end of the line using conventional methods, then transposition can be achieved, but large volumes and high lead times are generated
Solution Approach 1:
The transposition device is divided into multiple bar portions (first bar portion, second bar portion, third bar portion) that can be independently positioned and connected. This segmentation allows the device to achieve transposition functionality while maintaining a compact structure that reduces overall volume compared to conventional end-of-line transposition solutions.
2Adaptability or versatility
If custom transposition solutions are designed for each case, then specific transposition requirements are met, but production costs and lead times increase
Solution Approach 1:
The transposition device uses standardized bar portions with identical structural features (connection ends, positioning features) that can be universally applied to different transposition configurations. The same basic component design can accommodate various phase transposition requirements by simply changing the arrangement and connection configuration, eliminating the need for custom-designed solutions for each case and reducing production costs.
3Ease of operation
If bar portions are interrupted and bent to form end portions shifted outward, then space between end portions increases for electrical connection, but device complexity increases
Solution Approach 1:
The bar portions are bent to form curved or angled configurations with end portions shifted outward from the main busbar path. This curvature allows electrical connection points to be positioned externally where they are more accessible for connection while maintaining a relatively simple overall device structure. The bending creates natural spacing between adjacent bar portions without requiring complex mechanical assemblies.

AI summary
The present invention relates to a transposition device for a prefabricated electrical conduit. According to the invention, the transposition is carried out on the portion of bar located at one end of this set of bar portions, and the other bar portions further comprise a fold (20) such that each of the bar portions has two parts extending along parallel planes separated by a certain distance g from each other, this distance g being about half of that f separating the parts of bar portions before folding and the parts of bar portions after folding from the portion of bar located at the aforementioned end.
