Transformer Winding Assembly with Adjustable Lifting Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling high-voltage or extra-high-voltage transformers face challenges in creating a space-saving, mechanically safe, and electrical connection between windings, particularly in HVDC transformers, due to the need for valve line routing past the windings rather than directly between them.
Innovation Solution
A device with a lifting platform featuring adjustable elements allows for the arrangement and repositioning of windings around transformer cores, enabling direct connection of valve lines between windings by creating an intermediate space, which reduces the overall size requirements and facilitates safe and efficient electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If valve outlet lines are guided past the windings at the side using conventional production technology, then the windings can be placed on transformer cores and fixed immediately, but this requires a large space on or inside the transformer and creates complex routing
Solution Approach 1:
The patent applies preliminary action by equipping the lifting platform with adjusting elements that enable preliminary positioning of windings around transformer cores before final fixation. This allows valve outlet lines to be routed directly between windings from the beginning, eliminating the need for complex lateral routing and reducing transformer size.
2Productivity
If windings are fixed immediately after placement on transformer cores, then assembly is simplified, but this prevents direct connection of valve lines between windings and requires lateral routing
Solution Approach 1:
The patent applies dynamics by making the lifting platform adjustable with displaceable adjusting elements. This allows the platform to adapt its position dynamically during assembly - enabling windings to be positioned for direct valve line connection, then adjusted for optimal placement before final fixation, thereby simplifying both assembly and routing.
3Device complexity
If a lifting platform without adjusting elements is used, then the structure is simpler, but this prevents repositioning of windings for direct valve line connection between windings
Solution Approach 1:
The patent applies universality by designing the lifting platform with multi-functional adjusting elements that can perform multiple operations: lifting windings, positioning them around transformer cores, enabling direct valve line connection, and facilitating final fixation. This single device replaces what would otherwise require multiple separate tools or operations.
