Integrated Switching Spark Gap with Damping Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-voltage impulse testing systems require significant space and incur high capacitive loads due to the physical size and separate arrangement of auxiliary components like cut-off gaps and overshoot compensation, making them inefficient and costly to operate and reconfigure for different tests.
Innovation Solution
A controlled switching spark gap is integrated with an additional damping unit comprising a series-connected damping resistor, inductor, and spark gap, which reduces oscillations and capacitive loads, allowing for a single auxiliary component to combine switching spark gap and overshoot compensation functions, and can be easily moved and reassembled with a voltage divider on a common base frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate auxiliary components (cut-off gaps and overshoot compensation) are used in high-voltage impulse testing systems, then the system can perform required testing functions, but the physical size and capacitive loads increase significantly
Solution Approach 1:
The patent combines the cut-off gap and overshoot compensation components into a single integrated switching spark gap device. The damping unit with parallel-connected spark gap is integrated directly into the switching spark gap structure, eliminating the need for separate auxiliary components while maintaining both cut-off and overshoot compensation functions.
Solution Approach 2:
The switching spark gap is designed to perform multiple functions simultaneously: it acts as both the cut-off gap for voltage interruption and the overshoot compensation element through its integrated damping unit. This multi-functional design reduces the number of separate components needed in the high-voltage impulse testing system.
2Adaptability or versatility
If separate auxiliary components are used, then the system can be configured for different tests, but the operational complexity and reconfiguration effort increase
Solution Approach 1:
By merging the cut-off gap and overshoot compensation into a single integrated switching spark gap, the patent reduces the number of separate components that need to be arranged and reconfigured. The integrated design simplifies the overall system structure while maintaining the ability to perform different test configurations.
3Reliability
If separate auxiliary components are used, then the required testing functions are achieved, but the space requirements and production costs increase
Solution Approach 1:
The integration of the damping unit into the switching spark gap structure eliminates the need for separate auxiliary components, thereby reducing the overall space requirement in the test shop. The combined structure occupies less area while providing the same testing functionality.
