Integrated On-Load Tap Changer Module for Compact Switching Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
On-load tap changers require a complex and space-consuming structure due to the arrangement of diverter switches, selectors, and motor drives, which are costly and inefficient.
Innovation Solution
The on-load tap changer module integrates the diverter switch, selector, and change-over selector onto a single carrier, activated centrally by a drive module, reducing structural complexity and space requirements while maintaining precise operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the diverter switch, selector, and motor drive are arranged in a conventional distributed structure, then each component can be independently designed and maintained, but the overall structural space and complexity increase significantly
Solution Approach 1:
The patent combines the diverter switch, selector, and motor drive onto a single carrier, creating an integrated on-load tap changer module. This merging of previously distributed components into a unified structure directly reduces the overall structural space while maintaining the functional independence of each component through modular design on the carrier.
Solution Approach 2:
The carrier serves multiple functions simultaneously: it acts as a mounting structure for the diverter switch, supports the selector mechanism, and provides the framework for motor drive integration. This multi-functionality allows a single component (the carrier) to replace what would traditionally require multiple separate structural elements, thereby reducing space.
2Adaptability or versatility
If the diverter switch, selector, and motor drive are arranged in a conventional distributed structure, then component independence is maintained, but the device complexity and cost increase
Solution Approach 1:
The patent segments the on-load tap changer into a modular assembly where the diverter switch, selector, and motor drive are distinct functional units mounted on a common carrier. This segmentation maintains the independence and adaptability of each component while organizing them into a simplified, integrated structure that reduces overall complexity.
Solution Approach 2:
By merging the mounting and support functions into the carrier, the patent eliminates the need for separate structural frameworks that would traditionally connect these components. This reduces the number of parts and interconnections, thereby simplifying the overall device structure while preserving component independence.
3Manufacturing precision
If a conventional distributed arrangement is used, then each component can be optimized independently, but the overall system becomes more expensive and space-consuming
Solution Approach 1:
The carrier provides localized mounting areas and structural support tailored to each component's specific requirements. This allows each component (diverter switch, selector, motor drive) to be optimized independently for its function while being integrated into a compact unified structure, achieving both component optimization and space efficiency.
