Solution Overview
Problem
Existing grounding resistance reducing materials, such as coke powder, generate significant carbon dioxide emissions during manufacturing and are heavy, making them costly and difficult to transport, especially in mountainous areas where machinery cannot be used.
Innovation Solution
A grounding resistance reducing material composed of carbide granules obtained by incomplete combustion of biomass, mixed with hydraulic powder, is used between the grounding electrode and soil to reduce grounding resistance while minimizing carbon dioxide emissions and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If coke powder from fossil fuel is used as grounding resistance reducing material, then grounding resistance reduction effect is achieved, but carbon dioxide emission increases and weight is heavy
Solution Approach 1:
The patent changes the material composition from fossil fuel-based coke powder to biomass-based carbide granules, altering the chemical origin while maintaining the electrical conductivity parameter. This substitution reduces carbon dioxide emissions by using renewable biomass resources instead of depleting fossil fuels, while preserving the grounding resistance reduction effect through comparable specific resistance values.
Solution Approach 2:
The patent creates a composite material system combining carbide granules with hydraulic cement and water. This composite approach allows the carbide granules to provide electrical conductivity for grounding resistance reduction while the hydraulic cement provides structural binding, achieving both functional requirements without relying on heavy fossil fuel-based materials.
2Quantity of substance
If coke powder is used as grounding resistance reducing material, then grounding resistance reduction effect is achieved, but weight is heavy making transport difficult
Solution Approach 1:
The patent changes the density parameter of the grounding material by substituting dense coke powder with lighter carbide granules derived from biomass. This parameter change reduces the weight of the material while maintaining the volume and distribution characteristics necessary for effective grounding resistance reduction, thereby facilitating manual transport to remote locations.
3Object-generated harmful factors
If biomass-derived carbide granules are used, then carbon dioxide emission is reduced and weight is trimmed, but specific resistance may increase
Solution Approach 1:
The patent optimizes the specific resistance parameter of biomass-derived carbide granules through controlled carbonization processes and material composition adjustments. By adjusting the carbonization conditions and granule size distribution, the specific resistance is reduced to levels comparable with or better than fossil fuel-based coke powder, ensuring effective grounding performance while maintaining the environmental and weight advantages of biomass materials.
