C4F7N, a brand-new environmentally friendly gas manufactured this year
The fluorine-contained gases exemplified by the sulfur hexafluoride and their mixtures are widely used in electrical appliances of power switcher. However, the greenhouse effect of the gas is 23500 times as much as that of carbon dioxide. The total amount of leaked SF6, in the year of 2017, gave rise to the equal effect of 1.3 million automobiles running on the roads within EU, and therefore the gas is listed as a restricted gas in discharge by the United Nations Framework Organization on Climate Change. The researchers constantly put out other fluorine-contained gases with lower effects of greenhouse but cannot resolve the problem of higher coefficient of greenhouses or higher temperature of gases’ liquefication, with the result of not achieving the fundamental “green” switchers. In summary , it is of great importance to achieve the target of reduction of emission in an effort to develop a fluoride-free electricity equipment while the fluorien-contained gases is strictly limited.
The last test was done and verified by the China High Voltage Testing Centre of Electrical Appliances in 2020, marking the initiating stage of C4F7N’s application in the ultra-high voltage electrical switcher system of 1000 kilovolts with the newest environmental friendly gas in the the world
