Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for grounding high-voltage electrodes in electrodynamic fragmentation systems rely on manual intervention, which is prone to human error and lacks visibility, posing safety risks due to potential high-voltage discharges during maintenance or process vessel access.
Innovation Solution
An automatic grounding device is coupled to the high-voltage electrode and process vessel, ensuring the electrode end is grounded when made accessible, using a lever mechanism actuated by gravity or spring force, providing reliable and visible grounding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual grounding methods (earthing rod or grounding switch) are used, then the high-voltage electrode can be grounded, but the grounding reliability depends on human diligence and is not visually verifiable
Solution Approach 1:
The grounding device automatically grounds the high-voltage electrode when the process vessel is opened or removed, without requiring manual intervention. The device self-activates through the mechanical movement of the electrode or vessel, ensuring grounding occurs by default whenever access is required, eliminating reliance on human diligence.
Solution Approach 2:
The grounding device incorporates a visual indicator (such as a color-coded flag or positioned element) that changes position or color to clearly show whether the electrode is grounded or not. This provides immediate visual verification of the grounding status, making it observable without requiring technical inspection.
2Reliability
If the grounding switch of the high-voltage generator is used, then grounding can be achieved, but the operating status is often not visible and the discharge resistor may be defective
Solution Approach 1:
The grounding device automatically grounds the high-voltage electrode when the process vessel is opened or removed, without requiring manual intervention. The device self-activates through the mechanical movement of the electrode or vessel, ensuring grounding occurs by default whenever access is required, eliminating reliance on human diligence.
Solution Approach 2:
The grounding device incorporates a visual indicator (such as a color-coded flag or positioned element) that changes position or color to clearly show whether the electrode is grounded or not. This provides immediate visual verification of the grounding status, making it observable without requiring technical inspection.
3Ease of operation
If manual grounding procedures are followed, then grounding can be performed, but accidents can occur due to carelessness or lack of visibility
Solution Approach 1:
The grounding device is positioned and configured in advance so that it automatically contacts and grounds the high-voltage electrode as soon as the process vessel is opened or removed. This preliminary positioning ensures that grounding occurs before any personnel can approach the electrode, eliminating the risk of accidental discharge during maintenance or reloading operations.
Solution Approach 2:
The grounding device automatically grounds the high-voltage electrode when the process vessel is opened or removed, without requiring manual intervention. The device self-activates through the mechanical movement of the electrode or vessel, ensuring grounding occurs by default whenever access is required, eliminating reliance on human diligence.

AI summary
The invention relates to an arrangement comprising a high voltage electrode (1) and a process vessel (2) that is associated with said high voltage electrode (1). The high voltage electrode (1) and the process vessel (2) can be placed relative to one another in such a way that the operational end (5) of the high voltage electrode (1) is immersed in the process vessel (2) in an operating position while being disposed outside the process vessel (2) in an off position. The arrangement further comprises a grounding device (3) which is embodied so as to automatically enter in contact with the operational end (5) of the electrode in order to ground the high voltage electrode (1) when the same is placed in the off position. The inventive arrangement makes it possible to create electrodynamic fragmentation systems in which the high voltage electrode (1) is automatically and reliably grounded when the operational end (5) thereof becomes accessible while the grounding can actually be seen, thus significantly improving personnel safety.
