Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintenance personnel in electrical substations face significant safety risks due to the proximity of high-voltage components, where de-energized components are adjacent to energized ones, posing a danger of accidental contact and injury during repair or replacement.
Innovation Solution
A safety device comprising a safety barrier board made of insulating material, equipped with fastening devices such as inverted-J-hooks and variable length chains, is positioned between adjacent electrical circuit components to create a physical and visual barrier, preventing accidental contact with energized components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If components are placed close together to reduce substation size, then space utilization is improved, but safety risk increases due to proximity of energized and de-energized components
Solution Approach 1:
The patent introduces an intermediary safety barrier device positioned between energized and de-energized components. This barrier acts as a mediator that physically separates the two zones, preventing accidental contact while allowing the components to remain in close proximity for space efficiency.
Solution Approach 2:
The safety barrier extracts the harmful electrical field interaction by creating a physical and electrical separation zone. By removing the direct proximity risk, the system maintains compact layout while eliminating the safety hazard of accidental contact between energized and de-energized components.
2Reliability
If redundant components are provided in parallel for reliability, then system reliability is improved, but safety complexity increases due to multiple energized circuits near maintenance areas
Solution Approach 1:
The safety barrier divides the substation space into distinct segmented zones: energized zones and de-energized maintenance zones. This segmentation creates clear spatial boundaries that simplify safety management, allowing redundant components to operate reliably while maintaining organized, manageable safety zones.
3Ease of operation
If maintenance personnel work on de-energized components, then system maintenance is enabled, but risk of accidental contact with energized components increases
Solution Approach 1:
The safety barrier is deployed in advance before maintenance work begins, creating a pre-established protective zone. This preliminary protective action prevents the harmful effect of accidental contact before it can occur, allowing maintenance personnel to work safely on de-energized components without exposure to energized circuits.
4Object-affected harmful factors
If visual and physical barriers are introduced for safety, then safety protection is improved, but device complexity and space requirements increase
Solution Approach 1:
The safety barrier employs a flexible, thin-film insulating structure that provides effective electrical isolation without requiring bulky or complex rigid enclosures. This thin-film approach delivers comprehensive safety protection while minimizing the barrier's own physical footprint and structural complexity.

AI summary
A safety device is configured to be attached to components in an electrical substation to provide a physical and visual barrier between de-energized components and energized components in the electrical substation. The safety may include a safety barrier board formed from an electrically insulating material and configured to be attached to fastening devices that attach the safety barrier board to components in the substation. Each fastening device may be an inverted-J-hook configured to be attached to a surface of the safety barrier board or a coupling link attached to a variable length fastening component and an attachment hook.
