Stacked Spark Gap Support Unit with Integrated Insulating Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier units for spark gaps require additional isolating distances and insulating bodies when stacked in series, increasing production and assembly complexity.
Innovation Solution
A box-shaped insulating body with chamber-like recesses adapted to disc-shaped spark gap electrodes, where the recesses serve as isolating gaps and electrode holders, eliminating the need for separate spacer elements and allowing for easy assembly and integration of spark gaps into a single module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate insulating bodies and spacer elements are used to accommodate and center spark gap electrodes, then the electrodes can be properly isolated and positioned, but the production outlay and assembly complexity increase
Solution Approach 1:
The patent combines multiple separate components (insulating body and spacer element) into a single integrated insulating body with recesses. The insulating body now performs both the function of electrical insulation and the function of spacing/positioning the spark gap electrodes, eliminating the need for separate spacer elements and reducing assembly complexity
Solution Approach 2:
The insulating body is designed to serve multiple functions simultaneously: it provides electrical insulation between electrodes, maintains spacing between consecutive electrodes, centers the electrodes through complementary recesses, and provides structural support for the stack assembly. This multi-functionality reduces the total number of components required
2Reliability
If additional isolating distances and insulating bodies are provided for stacked spark gaps, then proper electrical insulation is achieved, but production and assembly outlay increase
Solution Approach 1:
The insulating body integrates the isolating distance function into its structure by forming recesses with complementary contours to the electrodes. These recesses automatically provide the required spacing and insulation without requiring additional separate insulating disks or spacer elements, thereby reducing production outlay and simplifying assembly
Solution Approach 2:
The insulating body is designed with multiple chamber-like recesses that are spatially segmented to accommodate individual spark gap electrodes. Each recess is isolated from others by partition walls within the insulating body, providing electrical insulation between adjacent electrodes while maintaining a compact single-piece structure

AI summary
The invention relates to a support unit for spark gaps that can be arranged in series and stacked, consisting of an insulating body, which has a recess corresponding to the contour of a disc-shaped spark-gap electrode, and comprising means for contacting the spark-gap electrode. According to the invention, the insulating body has in its recess a collar-shaped offset directed towards the centre, against which the respective spark-gap electrode comes to lie, wherein the dimensions of the collar-shaped offset have the effect of forming a gap and the insulating body is also provided with a radial opening that extends up to the recess for receiving the spark-gap electrode.
