Pivoting Impulse Voltage Generator for Compact On-Site Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing impulse voltage generators for testing high-voltage components are cumbersome and costly to transport and assemble on-site due to their large size and complex setup, making it impractical to perform impulse voltage tests on heavy power transformers without disrupting power distribution networks.
Innovation Solution
A test arrangement with a movable impulse voltage generator that can pivot between horizontal and vertical positions within a cuboid container, allowing for compact transportation and assembly, along with integrated surge arresters and voltage dividers that can also pivot, reducing on-site assembly time and increasing operational efficiency.

Engineering Contradiction Analysis
1Loss of energy
If impulse voltage generator and test components are assembled on-site in original location, then transportation costs are avoided, but assembly time and operational complexity increase significantly
Solution Approach 1:
The test arrangement is divided into modular components (impulse voltage generator, voltage divider, measurement apparatus) that can be independently packaged and transported. Each module is designed as a self-contained unit that can be quickly assembled on-site, reducing both transportation complexity and assembly time.
Solution Approach 2:
The impulse voltage generator is placed horizontally within the cuboid container during transportation, with other test components nested around it. The generator then pivots to a vertical operating position, allowing compact storage while maintaining full functionality. This nesting approach maximizes space utilization and reduces transportation footprint.
2Reliability
If impulse voltage generator is designed with fixed vertical position for operation, then electrical isolation is maintained, but transportation and positioning become cumbersome
Solution Approach 1:
The impulse voltage generator is designed with a pivoting mechanism that allows it to dynamically change between horizontal (transport) and vertical (operation) positions. This dynamic capability enables the system to adapt to different operational states, maintaining electrical isolation during operation while facilitating easy transportation when horizontal.
Solution Approach 2:
The generator's orientation is changed from a fixed vertical dimension to include a horizontal dimension during transport. By utilizing both vertical and horizontal orientations, the system maintains electrical isolation properties in the vertical operating position while gaining transportation flexibility through horizontal positioning within the container.

AI summary
The embodiments relate to a test configuration for an impulse voltage test of electric high-voltage components with a lightning generator. The lightning generator can be moved between a first horizontal position within a cuboid container, and a vertical position relative to the container. A movement between the two positions includes a pivoting movement about a rotational axis. The proofing movement is transverse to the longitudinal direction of the lightning generator. The container can be closed at the top by at least one moveable cover.
