Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulating supports are used to hold busbars, then electrical insulation and protection are improved, but accessibility for connections is restricted
Solution Approach 1:
The insulating support is divided into multiple segments or sections along the busbar length. Each segment can be independently accessed or removed if needed, while maintaining continuous insulation coverage. This segmentation allows workers to access connection points without compromising the overall insulation protection.
Solution Approach 2:
Connection accessories or intermediary components are introduced that can interface with the insulating support structure. These intermediaries provide access pathways or connection interfaces through the insulated support, allowing electrical connections to be made while maintaining the insulation barrier.
2Strength
If multiple insulating supports are used to ensure electrodynamic withstand, then structural strength is improved, but device complexity increases
Solution Approach 1:
Multiple insulating supports are merged into a single integrated insulating structure that spans the entire busbar length. This unified structure provides the necessary electrodynamic withstand strength while reducing the number of separate components, simplifying the overall device complexity.
Solution Approach 2:
The insulating support is constructed using composite materials that combine high mechanical strength with excellent electrical insulation properties. This allows a single support structure to provide both the required electrodynamic withstand and insulation, eliminating the need for multiple separate supports.
3Object-affected harmful factors
If insulating supports house busbars over entire length, then protection against electric arcs is improved, but heat dissipation is restricted
Solution Approach 1:
The insulating support structure incorporates localized heat dissipation features at specific points along the busbar, such as thermal vents or heat sinks positioned at connection points. These local features allow heat to escape from critical areas while maintaining continuous insulation coverage for arc protection along the entire busbar length.
Solution Approach 2:
Heat dissipation components are nested within or integrated into the insulating support structure itself. For example, thermal management elements are embedded within the insulation material or positioned in recesses of the support, allowing heat dissipation functionality to be contained within the protective insulation structure without compromising arc protection.
