SF6/N2 mixed gas is a widely used insulation medium in the power industry. In traditional GIS (gas insulated switchgear), SF6 gas has always been used as an insulation medium, but due to its high global warming potential, SF6 is gradually receiving attention. In contrast, SF6/N2 gas mixtures have attracted much attention as an environmentally friendly alternative. Below, we will explore the advantages, applications, and analysis methods of SF6/N2 gas mixtures.
Advantages of SF6/N2 mixed gas:
Compared with pure SF6 gas, SF6/N2 mixed gas has lower greenhouse effect and global warming potential. This means that in equipment using SF6/N2 gas mixtures, the impact on global climate change is reduced. In addition, SF6/N2 mixed gas also has low oxygen consumption, which can reduce the risk of equipment failure and improve equipment reliability.
Application areas of SF6/N2 mixed gas:
SF6/N2 gas mixtures are commonly used in power transmission and distribution equipment, such as GIS, substations, and circuit breakers. They can effectively isolate the high-voltage parts of electrical equipment and provide reliable insulation performance. In addition, SF6/N2 mixed gas can also be used for testing and detection of power devices, providing support for equipment operation and maintenance.
Let’s talk about the analysis method of SF6/N2 mixed gas. Common analysis methods include gas composition analysis and electrical performance testing. Gas composition analysis can determine the composition ratio of mixed gas by sampling and analyzing gas samples in the equipment. Electrical performance testing can evaluate the insulation performance, withstand voltage test, and arc extinguishing performance of mixed gases in power equipment.
In summary, SF6/N2 mixed gas is widely used in the power industry as an environmentally friendly insulation medium. It has a lower greenhouse effect and global warming potential, while providing reliable insulation performance. Through gas composition analysis and electrical performance testing, we can better understand and apply SF6/N2 gas mixtures.
