SF6
Green Global Gas (G3)
Composition: HeptaFluoro-iso-Butyronitrile + CO2 (CF3) 2CFCN + CO2
Performance: Insulation strength close to SF6, excellent arc extinction capability, and a global warming potential (GWP) below 98% of SF6, meeting Kyoto Protocol requirements.
Composition: A mixture of air and low-GWP gases in a specific ratio.
Performance: GWP reduced by nearly 100%, suitable for GIS equipment, balancing insulation and environmental requirements.
Chemical Bond-Based Molecular Design
Method: A multi-dimensional model (8 dimensions including insulation strength, GWP, and toxicity) was constructed using chemical bonds as descriptors through high-throughput virtual screening and machine learning algorithms.
Results: Candidate gases such as C4F7N and HFOs were screened, with some molecules showing similar performance to /ltz-40-5-indoor-high-voltage-sf6-circuit in key properties such as insulation strength and liquefaction temperature.
CF3OCF=CF2: High-throughput screening revealed excellent overall performance, but specific GWP data were not explicitly provided.
Recyclable Processing Solutions: Some alternative gases (such as AirPlus™) support recycling and reuse after decommissioning, reducing emissions.
Current mainstream alternative gases are represented by G3 and AirPlus™, and the combination of molecular design technology further expands the performance optimization space. Selection requires comprehensive consideration of equipment requirements, economic costs, and environmental standards.
